丹佛斯静态平衡阀
丹佛斯静态平衡阀Company Document number：WTUT-WT88Y-W8BBGB-BWYTT-19998一、丹佛斯(Danfoss)静态平衡阀的应用:丹佛斯(Danfoss)静态平衡阀广泛应用于空调、供热及生活热水系统，作为平衡各末端及环路流量之用。
丹佛斯(Danfoss)静态平衡阀宜用于定流量系统，即末端无控制阀或末端采三通调节阀的系统，解决静态水力平衡问题。
对于末端采用两通调节阀的变量系统，丹佛斯推荐采用动态压差平衡阀或动态压差平衡型电动调节阀，相关信息详见丹佛斯相关技术文件。
二、静态水力平衡分析：静态水力平衡问题是指在定流量系统或变量系统的满负荷及调式工况下，系统及各末端的流量与设计流量不一致，所造成的水力平衡问题。
静态水力失衡发生的原因是系统固有的，主要有以下几点：1.各环路由于管道长度不同，造成的阻力损失不同2.各末端需用资用压力不同3.实际施工与设计的差异其主要表现有：1.各末端冷热不均，近热远冷（供热）或近冷远热（制冷）。
2.系统水量比设计流量大，系统大流量小温差运行。
3.水泵效率低下，功耗较额定值大根据图1所示，在系统中远离水泵的末端资用压差不足，流量无法达到设计要求；而靠近水泵的末端资用压差过余，流量超过设计要求，造成系统水量分布不匀。
而整个系统总水量也大于泵额定值。
、在图2中，可以看到在理想状况下，水泵应工作于设计管道曲线与水泵扬程-流量曲线的交点（Q1,H1），此时水泵效率为η1，功率为P1；而实际运行中由于整个系统的过流，导致水泵工作于实际管道曲线与水泵扬程-流量的交点（Q2,H2），此时水泵效率由η1下降至η2，而功率由P1升高到P2。
静态水力失衡虽然是系统固有的，但是可以通过加装平衡阀，进行解决。
其中对于定流量系统，应采用静态平衡阀加以解决。
三、丹佛斯(Danfoss)静态平衡阀的工作原理及特点1、丹佛斯(Danfoss)静态平衡阀的工作原理静态平衡阀亦称：手动平衡阀、数字锁定平衡阀等，它的工作原理是通过改变阀芯与阀座的间隙（开度），改变阀门内部流通面积，通过调节阀门流通能力，达到调节流量的目的，简而言之，静态平衡阀是一个局部阻力可以改变的节流元件。

丹佛斯压差控制阀说明书
丹佛斯压差控制阀说明书丹佛斯压力开关KP系列的安装及使用众所周知，在一般的制冷系统中，都会用到高低压力开关，用来控制压缩机的启停、风机启停，从而确保制冷系统的正常运行。
今天和大家简单的交流一下压力开关KP的安装和使用。
KP的安装在托架上或者在纯平表面上安装KP压力控制器。
也可以在压缩机上安装压力控制器。
在不利条件下，角铁托架可能会增强安装平面的振动。
因此在出现强烈振动的地方应始终使用墙装托架。
如果有出现水滴或水雾的风险，则必须使用附带的顶板。
顶板可将外壳的防护等级增加到IPIP 44并且适用于所有的KP压力控制器。
要达到IP 44的防护等级，必须将控制器安装在角铁托架(060-105666)或墙板托架(060-105566)上来盖住其背板上的孔。
包含自动复位功能的所有装置均配有顶板。
带有手动复位的装置也可以使用顶板，但在这种情况下，必须单独购买（单压，代码为060-109766；双压，代码为060-109866）。
如果装置要用在污浊的条件下或者暴露在浓重的水雾中—从顶部或从侧面—则必须安装防护帽。
防护帽可与角铁托架或墙装托架一起使用。
如果装置存在暴露在多水环境中的风险，则当产品安装在特殊IP55外壳中后可达到更高的防IP 55护等级。
IP 55外壳有单压(060-033066)和双压(060-035066)可供选择。
控制器的压力管连接必须始终以正确的方式安装到管路上，即使液体不会聚积在波纹管底部。
尤其是在以下情况下，很可能会出现该风险：装置位于很低的周围环境中时，例如在气流中在管路的底部进行连接时。
这样的液体可能会损坏高压控制器。
因此，压缩机的振动得不到抑制并可能引发触点颤动。
放置多余的毛细管如果发生振动，多余的毛细管可能会破裂并导致失去所有的系统充注物。
因此遵守以下原则便显得非常重要：当直接安装在压缩机上时：固定毛细管，使压缩机/控制器装置作为一个整体一起振动。
必须盘起并扎紧多余的毛细管。
注意：根据EN规则，禁止使用毛细管来连接安全压力控制器。

KP Pressure SwitchesDanfoss KP switches are used for regulating, monitoring and alarm systems in the industry. They provide automatic limit protection or manual reset limit protection for pressure systems. Can be used with steam, air, gaseous and liquid media. The pressure switches are fitted with single-pole changeover switch (SPDT). The position of the switch depends on the setting of the pressure switch and the pressure in the connector.KP ThermostatsKP thermostats are temperature-operated electric circuit breakers. The thermostats are fitted with single-pole changeover switch (SPDT).The position of the switch depends on the thermostat setting and sensor temperature. A KP thermostat can be connected and switch to single-phase alternating current motors of up to 2 kW.Features Approvals • Wide regulating range• Small dimensionsSpace-saving, easy to install in panels• Shock and impact resistant• Ultra-short bounce time.Limits wear to an absolute minimum andincreases reliability• Snap action electrical contacts minimize chatter,bounce, and wear, and ensure long termelectrical and mechanical reliability• Electrical connection from front of the unit.Makes rack mounting easier and also saves space• Suitable for alternating current and direct current• Screwed wiring, makes rewiring easy• Manual trip allows electrical function test withouttools• Versions with automatic and manual resetavailableUL listed for USA and Canada according to UL 353and UL 873CE marked in accordance to EN 60947-4/05PRESSURE SWITCHESOrdering Technical dataContact system and applicationSetting Cut-in and cut-out pressures of the systemshould always be checked with an accuratepressure gauge.Pressure setting for switches with automaticreset.Set the cut-out pressure on RANGE scale anddifferential on DIFF scale.Note:Restart pressure is equal to cut-out pressure minusdifferential value.Pressure switches with manual resetSet the cut-out pressure on the RANGE scale.

The time over which contact force reaches zero is a few milliseconds; therefore, contact bounce cannot occur as a result, for example, of slight vibrations before cut-out. The snap-action contact system will continue to function even when micro-welds arecreated between the contacts during cut-in. The force created to separate the contacts is strong, and instantly shears off all contact surface welds that have been created as the result of cut-in ac-tion.

丹佛斯压力开关用途功能原理
丹佛斯压力开关用途功能原理
丹佛斯压力开关是一种常用的压力控制装置，广泛应用于各种工业和家用系统中。
其主要作用是监控系统中的压力变化，并根据设定的压力范围进行控制。
以下是丹佛斯压力开关的用途、功能和工作原理的简要描述：
用途：
1. 压力控制：丹佛斯压力开关可用于控制液体或气体系统中的压力，确保系统在安全范围内稳定运行。
2. 过压保护：当系统中的压力超过设定的上限值时，丹佛斯压力开关可以发出警报信号或自动切断系统以防止损坏或意外事故。
3. 欠压保护：当系统中的压力低于设定的下限值时，丹佛斯压力开关可以触发警报或切断系统以避免工作异常或损坏。
功能：
1. 压力检测：丹佛斯压力开关通过内置的传感器或测量元件，监测系统中的压力变化，并将其转化为电信号。
2. 压力调节：丹佛斯压力开关可根据用户的要求，通过调整内部设定值来控制系统的工作压力范围。
3. 信号输出：当系统中的压力超过或低于设定的阈值时，丹佛斯压力开关会产生相应的开关信号，以触发系统的操作或报警。
工作原理：
丹佛斯压力开关的工作原理基于压力的力学效应。
当系统中的压力作用于丹佛斯压力开关的感应元件（例如弹簧或膜片）时，感应元件会发生弯曲或变形。
这种变形通过机械机构传递给内部的开关装置，从而触发开关状态的改变。
当压力低于设定阈值时，开关处于断开状态，而当压力达到或超过阈值时，开关闭合。
请注意，以上描述仅为一般的原理解释，实际的丹佛斯压力开关结构和工作原理可能会因不同型号和应用领域而有所不同。

Set the cut-in pressure on the “CUT-IN” scale (range scale).2. Set the differential on the “DIFF” scale.The cut-out pressure must be above absolute vacuum (p e = -1 bar).For high pressure switches the restart pressure is equal to cut-out pressure minus differential.Pressure switches with manual resetSet the cut-out presure on the “CUT-OUT” scale (range scale).High pressure limiters can be manually reset when the pressure is equal to the stop pressure minus the differential.Note:For low pressure switches the restart pressure is equalto cut-out pressure plus differential value.Design / Function 1.

This means that the bellows is active only when the cut-in or cut out value is reached.The bellows is connected to the pressure of the controlled plant via the connector (7).Danfoss KPI pressure switches are designed so that the bellows moves in the sameproportion as the pressure switches change. To ensure a snap function on contact change over, an omega spring is located between bellows and contact system.Key sketch of KP pressure switchKey sketch of KPI pressure switchKey sketch of KP pressure switch, boiler versionDimensions [mm] and weights [kg]Pressure switch, types KP 35, KP 36, KPI 35, KPI 36 and KPI 38Dimensions [mm] and weights [kg] (Boiler version)IP55 enclosureWall bracket Angle bracketPressure switch, types KP 35 and KP 36Pressure switch, type KP 34Accessories for KP pressure switchesTechnical dataDual pressure switchPressure switch, type KP 44Dimensions [mm],weights [kg]and orderingWater supply from reservoir or wellThe contact system in the KP 44 has a snap-action function and allows the bellows moves only when the cut-in or cut-out value is reached.If water is running short in the well or reservoir, the pump will no longer be able to increase the pressure to the cut-out value. Consequently the pump will keep running - perhaps without water. However, the KP 44 pressure switch will stop the pump as soon as the righthand bellows pressure drops below the safety cut-out setting.The pump can be started again by lifting the impulse lever. The pump will continue to operate when the impulse lever is released, provided that the righthand bellows pressure is higher than the safety cut-out setting plus a fixed differential of 1 bar. If this is not the case, the pump will cut-out again indicating insufficient water supply.Pressurized water supply direct to pump When water supply fails on the inlet side, the pump will no longer be able to boost the pressure to the cut-out value. Consequently the pump will keep running - perhaps without water. However, the KP 44 pressure switch will stop the pump as soon as the pressure in the pump suction line drops below the safety cut-out setting. The pump will automatically start again when the pump suction pressure has reached the level of 1 bar above the safety cut-out setting.Automatic start-up will only take place if the righthand bellows is connected to the pump suction line. Air pockets should be avoided to prevent the pump from starting up on air pressure rise, without the presence of water.In a hydrophore system where water is pumped from a well or an open tank, both bellows are connected to a pressure outlet on the air side in the pump pressure line, if possible.In a booster system receiving pressurized water the righthand bellows is connected • to the low pressure side of the pump forautomatic start-up• to the high pressure side of the pump for manual start-upThe lefthand bellows is always connected to the high pressure side of the pump.1.

Manual cut-in is made by lifting the impulse lever and releasing it again when the pressure has increased by min. 1 bar.The safety cut-out setpoint is normallydetermined by the static pressure (the water column). However, in order to avoid disturbing signal interaction, care should be taken to ensure that the safety cut-out setting is at least 1.5 bar lower than the control pressure cut-in setting.

DC 13Snap functionA specific contact force is maintained until snap is initiated. The time over which contact force reaches zero is a few milliseconds; therefore, contact bounce cannot occur as a result, for example, of slight vibrations before cut-out. The snap-action contact system will continue to function even when micro-welds are created between the contacts during cut-in.The force created to separate the contactsis strong, and instantly shears off all contact surface welds that have been created as the result of cut-in action.These design features ensure that the cut-out point of the KP control remains very accurate and completely independent of the magnitude of the current load.Current ratings:AC – 1The alternating current rating, in amperes, of the non-inductive, slightly inductive loads or resistive furnacesAC – 3The alternating current rating, in amperes, of the squirrel-cage motors: starting, plugging, inchingAC – 15The alternating current rating, in amperes, of electromagnetic loads (>72VA)DC – 13The direct current rating, in amperes,of electromagnetsRange setting / Set pointThe pressure range within which the unit will give a signal (contact changeover).DifferentialThe difference between contact changeover on rising and falling pressure.The differential is a condition for stable automatic plant operation.Manual resetA unit with manual reset can onlybe restored to operational mode by activation of the external reset button.Min. reset units will restart after the pressure has risen by a value greater than that of the fixed differential.Max. reset units will restart after the pressure has fallen by a value greater than that of the fixed differential.Automatic resetUnits with automatic reset restart automatically after stop.Permissible operating pressureThe highest permissible constant pressureor pressure variation the unit can be exposed to.

2.假如丹佛斯压力开关需要频繁使用，那么每次使用完毕后，操作人员都要适时进行清理，将残留的被测介质排出，擦拭干净后才可投入下一次使用；假如长期不使用丹佛斯压力开关时，操作人员也需要定期打扫丹佛斯压力开关，防止灰尘堵塞在孔洞里，影响丹佛斯压力开关日后的正常工作。
3.针对不同的情况，适时对丹佛斯压力开关实行相应措施，如低温时，需要适时将丹佛斯压力开关的电缆等易冻部位进行包装，起到保温作用；反之，高温时，则要实行降温措施；丹佛斯压力开关的应用注意事项：丹佛斯压力开关的压力管连接必需始终以正确的方式安装到管路上，确保液体不会再波纹管底部聚集，特别是在以下两种情况简单显现该风险。
装置位于很低的四周环境中。
连接管安装与管路底部位置。
波纹管积液可导致①波纹管分裂②误动作机械式压力开关有着怎样的工作原理呢？压力开关是一种简单的压力掌控装置。
当被测压力达到额定值时，压力开关可发出警报或掌控信号。
机械式压力开关通常是用于低成本应用或加强牢靠性，这取决于开关信号的传输频率。
将开关设计为低需求模式（切换周期很少，如安全应用中）或高需求模式（切换周期频繁，如过程掌控中）。
回差通常是不可调的，因此无法配置切换的重置动作点，而需通过出厂设置进行预设。
机械式压力开关通常用于开断高强度电流，如泵和驱动装置。
然而，机械接点常常面临着PLC和现代电子中切换超低压的问题，除非使用价格更高的镀金接点。
机械式压力开关工作原理机械式压力开关为纯机械形变导致微动开关，当压力加添时，作用在不同的传感压力元器件（膜片、波纹管、活塞）产生形变，将向上移动，通过栏杆弹簧等机械结构，最后启动最上端的微动开关，使电信号输出。

The differential is fixed at 0.1 bar, i.e.the alarm will not cut out before the pressure rises to 0.9 bar. The lamp must be connected to terminals 1 and 2 in the pressure control.Example 2An alarm must be given by a bell when the pressure in a boiler rises to 10 bar. The normal operating pressure is 9 bar.Choose a KPS 36 (range from 6 to 18 bar).The range value of the pressure control must be set at 10 bar, the differential at 1 bar.The bell must be connected to terminals 1and 4.Example 3The pressure in a start air reservoir must be regulated with a compressor controlled by a KPS pressure switch so that it lies between 30 and 36 bar.Choose a KPS 45 (range 4 to 40 bar).The range value must be set at 36 bar.The differential of 6 bar must be set in accordance with the nomogram, fig. 10, at approx. 2 on the differential scale.The required start function is obtained by connection to terminals 1 and 2 in the pressure control.Mechanical differential Mechanical differentialFig. 8Fig. 98DKACT.PD.P10.E2.02Danfoss A/S 10-2003Pressure switches and thermostats, type KPSEN 60 947-4-1EN 60 947-5-1–10- 30 3-10 80 65 75 110 160 2060L3112 060L3113 KPS 7620- 603-14130-75---060L3118KPS 7720- 603-14130--110--060L3100KPS 7720- 603-14130--160-060L3136KPS 7720- 603-1413065751101602-060L3101060L3102KPS 7720- 603-14130--1101605060L3119060L3120KPS 7750-1004-16200 -75---060L3121KPS 7950-1004-16200--110-060L3103KPS 7950-1004-16200160060L3137KPS 7950-1004-1620065751101602060L3104060L3105KPS 7950-1004-16200--1101605060L3122060L3123KPS 7950-1004-16200--1101608060L3124060L3125KPS 7950-1004-16200-751101603060L3143KPS 7950-1009200-75---060L31411)KPS 7970-120 4.5-18220-75---060L3126KPS 8070-120 4.5-18220--110--060L3127KPS 8070-120 4.5-18220---160-060L3138KPS 8070-120 4.5-18220---200-060L3157KPS 8070-120 4.5-1822065751101602060L3128060L3129KPS 8070-120 4.5-18220-751101603060L3156KPS 8070-120 4.5-18220--1101605060L3130060L3131KPS 8070-120 4.5-18220--1101608060L3132060L3133KPS 8060-1505-2525065751101602060L3106060L3107KPS 8160-1505-25250--1101605060L3134060L3135KPS 8160-1505-252501101608060L3111KPS 8160-1505-25250200060L3110KPS 81100-2006.5-3030065751101602060L3108060L3109KPS 83100-2001830065751101602060L31391)060L31401)KPS 83Thermostats, introductionKPS thermostats are temperature-controlled switches. The position of the contacts depends on the temperature of the sensor and the set scale value. In this series, special attention has been given to meeting demands for : a high level of enclosure,robust and compact construction, resistance to shock and vibration.The KPS series covers most outdoor as well as indoor application requirements.KPS thermostats are suitable for use inmonitoring, alarm and regulation systems in factories, diesel plant, compressors, power stations and on board ship.KPS with rigid sensorKPS with remote sensorKPS with remote sensor and armoured capillary tube Approvals 1) Thermostat with max. reset.When ordering, please state type and code numberTechnical data and ordering Ship approvalsDet norske Veritas, Norway American Bureau of Shipping Lloyds Register of Shipping, UK F Germanischer Lloyd, Federal Republicof Germany (FRG)Bureau Veritas, FranceIncludes thermostats with fixed sensor and pressure controls with armoured capillary tube.U Underwriters Laboratories Inc., USA Registro Italiano Navale, Italy PPolski Rejestr Statków, PolandMRS, Maritime Register of Shipping,RussiaNippon Kaiji Kyokai, J apanCode nos.Mech.Max.Suitable Cap.Setting diff.sensor sensor length Tube Typerangeadjustable/temp.(see also lengthfixed“Accessories”)°C °C °C m m m9DKACT.PD.P10.E2.02Danfoss A/S 10-2003Pressure switches and thermostats, type KPSKPS 76:±3 °C KPS 80:±3 °C KPS 77:±3 °C KPS 81:±6 °C KPS 79:±3 °CKPS 83:±6 °CFig. 1Curve A gives the maximum load.Hatched area B: Acceptable load for the gold plating of the contact.Contact load (Alternating current):Ohmic:10 A, 440 V, AC-1Inductive: 6 A, 440 V, AC-34 A, 440 V, AC-15Starting current max. 50 A (locked rotor)Ambient temperature –40 to +70 °C Vibration resistanceVibration-stable in the range 2-30 Hz,amplitude 1.1 mm og 30-300 Hz, 4 G.EnclosureIP 67 to IEC 529 and DIN 40050.The thermostat housing is enamelled pres-sure die cast aluminium (GID-AlSi 12).

Therefore function is not affected whether the sensor is placed warmer or colder than the remaining part of thethermostatic element (bellows and capillary tube). However, such a charge is to some extent sensitive to changes in thetemperature and bellows and capillary tube.Under normal conditions this is of noimportance, but if the thermostat is to be used in extreme ambient temperatures there will be a scale deviation. The deviation can be compensated for as follows:Scale correction = Z × aZ can be found from fig. 4, while a is the correction factor from the table below.Correction factor a Regulation for thermostats Typerangewith with with rigid 2 and 5 m 8 m °Csensor cap.tube cap.tubeRelative scale setting in %Electrical connectionKPS thermostats are fitted with a Pg 13.5screwed cable entry suitable for cables from 5 to 14 mm.
