压力释放阀PRESSURE RELEASE VALVE使用说明书OPERATION INSTRUCTION明远电器设备SHENYANG MINGYUAN ELECTRIC EQUIPMENT CO., Ltd.本说明书适用于我公司生产的系列变压器用压力释放阀，阐述其用途、性能、规格、技术参数、使用及安装，供用户参考。

The Operation Instruction is applicable to pressure release valve of a series of transformers manufactured by our company, indicating its application, performances, specifications, technical parameters, usage and installation for uses’ reference.1. 压力释放阀用途和性能压力释放阀适用于油浸式电力变压器、电力电容器及有载分接开关等，用来保护油箱。

当油浸式变压器在运行中出现故障时，由于线圈过热，使一部分变压器油汽化，变压器油箱中压力迅速增加，这时压力释放阀在2ms迅速动作，释放压力，保护油箱不致变形或爆裂。

油箱的压力再升高而达到开启压力时，压力释放阀应再次动作，直到油箱的压力降到正常值。

由于压力释放阀动作后能可靠关闭，油箱外的水和空气不能进入油箱，变压器部不会受大气污染。

1.Application and performancePressure release valves play a vital role in the protection of oil-immersed electrical equipments, such as transformers, high voltage switch gears, capacitor and on load tap-changers, etc. This device can prevent the oil-immersed electrical equipment from deformation or rupture. Should a fault occur in such electrical equipment, from deformation of rupture? Should a fault occurring in such electrical equipment, they are instantaneously vaporize the oil causing extremely rapid build-up of gaseous pressure? If mounting this type pressure release device on the oil-tank, when the pressure reaches to its opening pressure, it opens automatically within 2ms and relieves the pressure.2．型号、规格及基本参数Type, specification and technical parameters2.1 型号的含义 Meaning of typeY S F□—□ / □□□特殊环境代号（Special environment）带机械信号标“J”（“J”：mechanical signal）带信号开关标“K”（“K”：electrical signal）两者都带标“KJ”（“KJ”：Both with signal）喷油有效口径（Caliber of oil-gushing tube）mm开启压力（Opening pressure）kPa设计序号（Design serial number）阀（valve）释放（release）压力（pressure）注：特殊环境代号 note: special environment:TA: 干热带地区 dry tropicTH: 湿热带地区 humid tropicT: 干、湿热带地区 dry、humid tropic例：YSF16-55/130KKJT开启压力为55kPa，喷油口径为φ130mm，带电信号、机械信号。

For prolonged exposure to concentrated brines, or strong mineral acids, consider the severe service coating.Severe Service CoatingFor situations demanding the highest corrosion resis-tance, consider the severe service coating.the body of the marsh hawk is coated with a red Fusion Bond epoxy (FBe) for resistance to mineral acids,(including sulphuric and hydrochloric acids up to 15%) high-chloride ion solutions (including alumi-num chloride, potassium chloride and brine) as well as many other petrochemicals.the marsh hawk internals are coated in a proprietary black PFa (teFLOn) providing the same excellent fluo-ropolymer chemical resistance as the FBe above.series 4000 marsh hawk trv with manual relief Optionseries 4000 marsh hawk trv with hard anodizationseries 4000 marsh hawk trv with severe service coatingO P T I O N S A N D AC C E S S O R I E S (C O N T I N U E D )S E A L C O N F I G U R AT I O N A N D M AT E R I A L S the series 4000 marsh hawk combines the pressure and vacuum valve in an innovative design that requires only one shared gasket.to improve valve sealing performance, gaskets are factory coated with a pliable silane-based sealant. an optional oil-based sealant for use in sour gas applica-tions is also available. Both sealants are available in small packages for maintenance and reapplication.hawkeye offers three material options for the pressure / vacuum seal, beyond the standard Fkm (viton®) seal.• For applications where sealing is the first priority and the vent is not expected to operate often and has low set pressures (under 4 ozsi), eFkm (sponge viton®) can be supplied.• For higher temperature, minimally freezing conditions and acid service FePm (aflas®) is available.• For extreme applications FFkm (kalrez®) is also available.the use of ePDm seals in any hawkeye vent is contra-indicated due to its unsuitability in common petrochem-ical applications.hawkeye does not offer or recommend using solid fluoropolymer (PtFe, PFa, FeP, etc.), nor expanded flu-ropolymer (gOre-tex®) as a gasket material and any venting device. although the material may be chemi-cally suitable, the harder crystalline polymer structure of these materials impedes sealing at the typically low interfacial pressures found in the marsh hawk, as well as other low-pressure (i.e. <15 psi) vents.GENE R A L FLU OROEL A STOM E R CHEM ICA L C OM PATI BI LI T Y¹FKM / VI TON N.B.¹ THIS CHART I S F OR R EFE REN CE ONLY.

Before piping is connected, it should be thoroughly blown out with air (flushing) or washed to remove chips, cutting oil and other debris from inside. Should they remain, they could cause malfunction.2. When screwing piping or fittings into ports, ensure that chips from the pipe threads or sealing material do not enter the piping. Also, if sealant tape is used, leave 1.5 to 2 thread ridges exposed at the end of threads.3. When screwing piping into a component, hold female threaded side and apply the recommended tightening torque. Insufficient tightening torque may cause loosening or sealing failure and excess tightening torque may cause damage to threads. Tightening without holding female threaded side, excess force is applied to the bracket directly, and may cause breakage.4. Do not apply torsion or bending moment other than the product's own weight. Support external piping separately as it may cause breakage. Non-flexible piping, such as steel tube piping, are prone to be affected by excess moment load or vibration. Use flexible piping in between to avoid such affects.5. For piping into the exhaust port, it is recommended to use a resin silencers (AN series). After tightening the silencer by hand, use a suitable wrench on the hexagonal flats to tighten an additional 1/4 turn. When installing one-touch fittings (KQ2 series) or the piping, add 1/2 turn after tightening by hand. Excess tightening torque may cause damage to threads.Warning1. Use clean air. Do not use compressed air which contains chemicals, organic solvent, synthetic oil or corrosive gas, etc., as it may cause breakage or malfunction.2. Install an air dryer or after cooler on upstream side. Air containing excess drainage may cause malfunction.Caution3. Install an air filter of 5 µm filtration on upstream side.4. Install a mist separator on upstream side to remove carbon powder from the compressor or other equipment. Excess carbon dust may cause malfunction.Refer to SMC’s “Air Cleaning Equipment” catalog for further details on compressed air quality.Recommended tightening torque Unit: N-m Thread size 1/8 1/4 3/8 1/2Torque 7 to 912 to 1422 to 2428 to 30Warning1.

Do not use in locations subject to vibration or impact.4. Do not expose to direct sunlight for an extended period of time. Protective cover should beused to shield.5. Do not mound in locations where is nearby heat source. Radiated heat should be alsoprevented.6. Implement suitable protective measures in locations where there is contact withwater droplets, oil, or welding spatter.7. Install a silencer into exhaust port to prevent the dust ingress if there is a lot of dust inatmosphere, as dust may cause air leakage.Warning1. When equipment is to be removed, first confirm that measures are in place to preventworkpieces from dropping, run-away of equipment, etc.. Then cut off the supply air pressure and electric power, and exhaust all compressed air from the system using its residual pressure release function.When the equipment is to be restarted after remounting or replacement, first confirm that measures are in place to prevent lurching of actuators and then confirm that equipment operates normally.2.

After taking off the cover of the electronic housing, the serial interface to adjust the settings is accessible. The menu controlled Windows program «PASO» allows easy adjustment of all variable settings. Data are stored in a non-volatile memory. Even after an electric power failure settings can easily be reproduced and transmitted.APPLICATIONProportional pressure relief valves with inte-grated electronics are well suited for demanding applications, in which the pres-sure frequently has to be changed. They are implemented in systems calling for good valve-to-valve reproducibility, easy installati-on, comfortable operation and high precision in industrial hydraulics as well as in mobile hydraulics. The proportional pressure relief catridge is very suitable for mounting in control blocks, flange bodies and sandwich plates size NG4-Mini and NG6.

The minimum pressure drop is obtained when the pilot valve is also de-energized . The total pressure drop through the venting 2-way valve and pipework is additive to the pressure at P . While the valve is vented the system pressure cannot be controlled via the proportional solenoid . This control feature is frequently used during off-load periods in machine cycle times . If lower off-load system pressures are required then additional full flow unloading valves are recommended, e .g . Vickers™ CV series cartridge valves .

For effective protection the user electrical cabinet, the valve subplate or manifold and the cable screens should be connected to efficient ground points. The metal 7 pin connector part no. 934939 should be used for the integral amplifier. In all cases both valve and cable should be kept as far away as possible from any sources of electromagnetic radiation such as cables carrying heavy current, relays and certain kinds of portable radio transmitters, etc. Difficult environ-ments could mean that extra screening may be necessary to avoid the interfer-ence. It is important to connect the 0V lines as shown above. The multi-core cable should have at least two screens to separate the demand signal and monitor output from the power lines. The enable line to pin C should be outside the screen which contains the demand signal cables.User Panel shellKB..

呼吸机中英文介绍

（如有重复，纯属我懒）平时在使用呼吸机的时候，存在很多英语单词、缩写和短语，如果不了解它的意义，容易给操作和治疗带来困扰，而且由于呼吸机品牌繁多，命名又不统一，更是容易造成混淆和误解。

在这里，把常见的机械通气相关的英语专用名词做一个汇总，并进行简单的注释，希望能够给大家日常的应用带来一些方便。

Install the O-ring in the groove on either the Pressure Relief Valve casting or the integrated galvanic isolator.2. Place the PRV in the desired orientation. Be sure that the PRV is aligned with the opening Tightening the bolts with the PRVtilted to one side may damage the galvanic isolator.3. Apply a drop of thread locking compound on the threads of the bolts to prevent them from coming loose.4. Loosely install the bolts through the ﬂ ange of the PRV.5. Uniformly tighten the bolts 3 time each in an alternating pattern to a ﬁ nal torque of 140in/lb.1234Tighten bolts in an alternating pattern as shown at left.Complete the pattern for each bolt ﬁ rst to 40 in/lb,then to 80 in/lb, and ﬁ nally to 140 in/lb.3.3 USE WITH SALT WATERUse with salt water is permissible provided the equipment is thoroughly cleaned with fresh water after each use. The service life ofthe equipment may be shortened due to the e ﬀ ects of corrosion, and is not covered under warranty.4.0 RELIEF VALVE PRESSURE SETTINGTo set the relief valve pressure, turn the adjusting screw on the relief valve housing until the surface of the screw is even with the step marked with the desired pressure.Do not cap or plug discharge opening.To turn o ﬀ the Pressure Relief Valve, align the adjusting screw with the OFF position. Placing the Pressure Relief Valve in the OFF position prevents the valve from venting water. Do not use the OFF position for normal operations. System damage may occur if the Pressure Relief Valve is in the OFF position and the system exceeds its operating limits.The Pressure Relief Valve meets the requirements of NFPA 1901.90 PSI200 PSIOFFUse a 1/4” (7mm) hex key or 9/16” (14mm) socket/wrench when setting the height of the adjusting screw to the desired relief pressure.The Pressure Relief Valve is disabled in the OFF position and oﬀ ers no system protection against over-pressurization. Avoid water hammer or other pressure spikes during pump tests. Ensure PRV is returned to its normal pressure setting following pump testing.Severe water hammer may cause pressure spikes exceeding the Pressure Relief Valve’s capacity. Large spikes can result in injury from ruptured hose or system components. Review ﬂ ow capacity of the Pressure Relief Valve. Add more PRVs if additional ﬂ ow capacity is needed. Always operate valves slowly to avoid the risk of water hammer.5.0 RELIEF VALVE FLOW vs. PRESSURE CURVE6©Copyright Task Force Tips LLC 2004-2019 LIA-202 November 12, 2019 Rev056.0 WARRANTYTask Force Tips LLC, 3701 Innovation Way, Valparaiso, IN 46383-9327 USA (“TFT”) warrants to the original purchaser of its Pressure Relief Valve (“equipment”), and to anyone to whom it is transferred, that the equipment shall be free from defects in material and workmanship during the ﬁ ve (5) year period from the date of purchase.TFT’s obligation under this warranty is speciﬁ cally limited to replacing or repairing the equipment (or its parts) which are shown by TFT’s examination to be in a defective condition attributable to TFT.

Since the Pressure Relief Valve may not need to open in normal use, it is important that it be inspected at least quarterly for proper function per NFPA 1962 or annually per NFPA 1911, depending on the application. In particular, assure that:• There is no damage such as cracks or dents• There is no corrosion• Setting indications are readable• The waterway is clear of obstructions• The valve opens at the set pressureIf any problems are found, the Pressure Relief Valve should be removed from service until the problem is corrected. Any repaired Pressure Relief Valve must be tested before being placed in service.8.0 TESTINGIt is important that your Pressure Relief Valve (PRV) is functioning properly at all times while in service. A properly functioning PRV prevents dangerous situations and reduces possible injury. In order to ensure the PRV is functioning properly, it should be tested regularly. NFPA standards set forth the minimum requirements and procedures for inspecting and testing these valves. It is strongly recommended that you read and follow the procedures.For PRVs mounted to piping of in-service emergency vehicles:NFPA 1911: Inspection, Maintenance, Testing, and Retirement of In-Service Emergency VehiclesFor PRVs mounted to a ﬁ re hose appliance:NFPA 1962: Standard for the Care, Use, Inspection, Service Testing, and Replacement of Fire Hose, Couplings, Nozzles, and Fire Hose AppliancesAny valves taken out of service due to failure should be returned to the factory for repair or replacement.

1.压力释放阀用途和性能
压力释放阀适用于油浸式电力变压器、电力电容器及有载分接开关等，用来保护油箱。
当油浸式变压器在运行中出现故障时，由于线圈过热，使一部分变压器油汽化，变压器油箱中压力迅速增加，这时压力释放阀在2ms内迅速动作，释放压力，保护油箱不致变形或爆裂。油箱内的压力再升高而达到开启压力时，压力释放阀应再次动作，直到油箱内的压力降到正常值。由于压力释放阀动作后能可靠关闭，油箱外的水和空气不能进入油箱，变压器内部不会受大气污染。
The Operation Instruction is applicable to pressure release valve of a series of transformers manufactured by our company, indicating its application, performances, specifications, technical parameters, usage and installation for uses’ reference.

1.Application andperformance
Pressure release valves play avital role in the protection of oil-immersed electrical equipments, such as transformers, high voltage switch gears, capacitor and on load tap-changers, etc. This device can prevent the oil-immersed electrical equipment from deformation or rupture. Should a fault occur in such electrical equipment, from deformation of rupture?Should a fault occurring in such electrical equipment, they are instantaneously vaporize the oil causing extremelyrapid build-up of gaseous pressure?If mounting this type pressure release device on the oil-tank, when the pressure reaches to its opening pressure, it opens automatically within 2ms and relieves the pressure.
Example: YSF16-55/130KKJTin which, opening pressure is 55kPa,caliber of oil-gushing tube isφ130mmand flange erection, with electrical and mechanical signal and waterproof, use in dry、humid tropic。
