目录1.概述 (2)2.主要技术规范 (2)3.结构特点 (4)4.操作使用说明 (5)5.维护保养 (5)6.安装说明 (6)7.易损件明细 (7)1 概述PFF系列法兰式平行闸阀是按石油天然气行业标准和API Spec 6A-2004第19版规范要求进行设计、制造的，选用抗轻度腐蚀材料，作为含硫石油、天然气的油气井井口装置和各种管汇的组成部件。
2 主要技术规范注：用于API Spec 16C的阀门仅限于EE级材料。
3 结构特点3.1 法兰式平行闸阀是明杆带(或不带)尾杆结构，其密封机理是依靠阀板与阀座间的贴合实现金属刚性密封。
3.2 阀盖和阀体采用螺栓连接，阀盖和阀体间采用双面密封特殊垫环，以确保密封性能的安全可靠。
3.3 闸阀为明杆结构，带有平衡尾杆的明杆阀开关具有明显标志，且减轻了阀的开关力矩，不带平衡尾杆的明杆阀具有结构紧凑的特点。
3.4 阀板和阀座表面堆焊特殊合金，使之具有良好的耐磨性和抗腐蚀能力。
阀杆采用特殊材料，承压件采用特殊热处理工艺，DD、EE级阀具备抗轻度H2S腐蚀。
3.5 轴承座上设有润滑轴承的油嘴，便于现场加注润滑脂。
它的对方有润滑脂排出孔，可以观察润滑脂的加注情况。
3.6 阀杆升降螺纹采用梯形螺纹，顺时针方向为“关”，逆时针方向为“开”。
3.7 PFF法兰式平行闸阀结构见图1、图2、图3。
4 操作使用说明4.1 逆时针旋转手轮打开闸阀，可见阀杆上升，直到阀杆到达上死点，闸阀全部打开，然后手轮倒退1/4～1/2圈。
4.2 顺时针旋转手轮关闭闸阀，可见阀杆下降，直到阀杆到达下死点，闸阀处于全关，然后手轮倒退1/4～1/2圈。
4.3 由于该阀只起截流作用，不起节流作用，所以只有两个工作状态：全开或全关，不允许以部分开启方式作节流用，否则会影响阀的密封性能和寿命。
4.4 在运输过程中，应避免在手轮上拴起重绳索。
4.5 操作过程中，旋转手轮快到行程终点时，不可以太快。
5 维护保养5.1 盘根注脂若阀杆或尾杆密封处泄漏，可以通过单流注脂阀加注二次密封脂.注脂时应将阀(尾)杆旋至上(下)死点,利用阀(尾)杆的倒密封，将密封脂EM08（或7903）注入盘根。
阀门操作维护保养手册
1、手动阀门的正确操作手动阀门是设备和装置上使用很普遍的一种阀门，它是通过手柄、手轮来操作的。
一般情况下手柄、手轮顺时针旋转规定为关闭方向，逆时针旋转规定为开启方向。
但有的阀门启闭方向与上述相反，故操作前应注意检查启闭标志后再操作手动阀门，其手柄、手轮的大小是按正常人力设计的。
因此，在阀门使用上规定：不允许操作者借助杠杆和长扳手启、闭阀门。
同时，手柄长度、手轮直径小于320mm的，只允许一个人操作；直径等于或超过320mm的手轮，允许两人共同操作，或者允许一人借助适当的杠杆(一般长度不超过0．5m)操作。
但隔膜阀、非金属阀门是严禁使用杠杆或长扳手操作的，也不允许用过大、过猛的力关闭阀门有的操作者习惯使用杠杆和长扳手操作手动阀门，认为关闭力越大越好，其实不然。
这样会造成阀门过早损坏，甚至酿成事故。
实践证明：除撞击式手轮外，过大过猛地操作阀门容易损坏手轮、手柄，擦伤阀杆和密封面，甚至压坏密封面。
其次，手轮、手柄损坏或丢失后，应及时配齐，不允许用活扳手代用。
闸阀和截止阀之类的阀门，关闭或开启到头(即下死点或上死点)时要回转1/4～1/2圈，使螺纹更好密合，以有利操作时检查，以免拧得过紧损坏阀门。
较大口径的蝶阀、闸阀和截止阀，有的设有旁通阀。
旁通阀的作用是平衡进出口压差，减少开启力矩。
开启时，应先打开旁通阀，然后再开启大阀门。
开启蒸汽阀门前必须先将管道预热，排出凝结水。
开启时要缓慢，以免产生水锤现象，损坏阀门和设备。
开闭球阀、蝶阀、旋塞阀时，当阀杆顶面的沟槽与通道平行时，表明阀门在全开启位置；当阀杆向左或向右旋转90。
时，沟槽与通道垂直时，表明阀门在全关闭位置。
有的球阀、蝶阀、旋塞阀以扳手与通道平行为开启，垂直为关闭。
三通、四通阀门的操作应按开启、关闭、换向的标记进行，操作完毕后应取下活动手柄。
对有标尺的闸阀和节流阀，应检查调整好全开或全闭的指示位置。
明杆闸阀、截止阀也应记住它们全开和全闭的位置，这样可以避免全开时顶撞死点。

CCI阀门操作手册
阀门尺寸图中显示了允许的管段模具指标。
若因某种原因，管道的管段模具指标比阀门喷嘴高，必须通知我们出现的外力和力矩。 我们将根据这些指标检查阀体。若结果不可接受，应将重新调整管道系统。
5
对于阀门，我们建议在阀门上面和四周留有足够的空间以便于
拆卸
两个管绝不能连接成T-接头，防止对流（例如180°角）
阀门出口和接点之间的管长度必须不同。可避免导致回声。
4
温度测量点应尽量远离阀门，最小距离为4米。测量点不能离出口管接头和冷再加热器管太近，必须保证，当阀门关闭时，测量点的温度应比冷再热管的温度低（设置值）。
必须小心布置温度测量点，不要接触到水（阀门下游肘处的凝结水或水积聚，或未蒸发、离心的个别水）。
高旁阀紧紧固定在座上，因此上游不再需要隔离阀。若仍然装配了一个隔离阀（例如为了维护）必须保证高旁阀适当预热，并为运转做好准备（为运转做准备，隔离阀必须全开）。对具备安全功能的高旁阀（例如，所有TRD421）不允许有上游隔离阀。
入口管必须确保凝结水能流回流通蒸汽管，从而避免由于凝结水的形成导致的热震动。必须避免能出现水袋的管段。若做不到，管段必须装备具备充分能力和压差的恒动作排水设施。

四川东方300MW汽轮机高旁、低旁阀门操作手册
高旁、低旁操作高、低旁最小开度当锅炉点火启动后，蒸汽开始产生，随着“自启动”指令发出，此时操作员要把高旁和低旁打到预先设定的最小开度5%。
这么做的主要目的是为了充分冷却再热器和过热器。
随着信号DCS“自启动开始”并且高旁开到最小开度5%，此时如果高旁控制站的自动/手动处在自动位，则应切换为手动。
高旁升压随着着火越来越好并且锅炉产生的蒸汽越来越多，新蒸汽压力要按照确定的锅炉升负荷速率增加到最终高旁启动压力，在这个时候，低旁压力控制器在定压控制模式下。
当新蒸汽压力达到2MPa时，运行方式转换为升压模式，高旁压力控制器设定点切换为计算出的设定点。
自动/手动切换到自动高旁压力控制器的压力设定点按照汽机（冷态、温态、热态、极热态）的启动升压速率（冷态0.04MPa/min；温态0.08MPa/min；热态0.14MPa/min；极热态0.18MPa/min）变化到最终目标压力（冷态5.9MPa；温态8.52 MPa；热态8.52 MPa；极热态12.8MPa）。
当控制器输出值达到最小开度5%时，升压速率设为0，设定点压力保持，这意味着升压过程中断（此过程在锅炉产汽量小于设定点或产生着火问题时通常发生）。
在压力保持过程中，操作员只可以在压力控制器手动模式下调整值。
当中断消除并且高旁压力控制器输出超过10%时，升压过程继续进行，直到最终高旁目标压力（冷态5.9MPa；温态8.52 MPa；热态8.52 MPa；极热态12.8MPa）。
高旁定压控制当蒸汽压力由高旁压力控制阀控制时，汽机冲转（升速至1500rpm最后直至定速3000rpm），同期并网带负荷。
汽机的正常启动方式是中压缸启动在中压缸切换到高压缸的过程中，高压缸入口阀开，高旁阀关。
当蒸汽压力达到目标压力时，操作模式切换为定压控制方式自动/手动处在自动位高旁阀采用最终高旁目标压力控制方式下随着汽轮发电机同期并网信号发出，高旁最小开度功能切除当汽轮机进汽，旁路相应关闭当高旁阀关，并且汽轮机同期并网信号和切缸完成信号激活，高旁将进入跟随模式高旁跟随模式（相应低旁跟随模式）压力随锅炉负荷变化，压力的增长受高旁跟随最大压力梯度限制（0.6MPa）旁路应该保持关闭，除非压力突升高旁自动/手动控制站应在自动位高旁压力控制器的目标设定值应该是实际新蒸汽压力加上一个高旁压力偏移量（0.4MPa），所以高旁压力控制阀处于关闭位。

阀门操作、维护和使用手册说明(阀门投标专用)
阀门储存、操作、维护和使用说明概述阀门是用来关闭和开启管道中介质。
切断阀没有节流的功能。
该类阀门顺时针旋转手轮，直到完全将通道切断，阀门关闭。
逆时针旋转手轮，直到碰到阻挡，阀门打开。
对于电动装置阀门，在断电等紧急情况下，可以使用备用手轮打开和关闭阀门。
注意!截止阀在不超过10%开启状态连续节流会对阀瓣和阀座引起剧烈振动、噪音、磨损和损坏。
止回阀作为控制管道介质单向流动的元件，当介质顺流时由管线自身压力的作用开启阀门，当介质倒流时依靠阀瓣自身重量、弹簧力和介质回流的压力作用在阀瓣背部，使阀瓣与阀座形成密封，达到止回截流的目的。
警告！禁止用夹泵的方式对阀门进行泵验。
1.阀门的储存1.1发运准备阀门的包装应能防止阀门在运输过程和储存时不发生任何损坏。
并应注意以下几点：①闸阀：包装时，闸板应处于关闭状态。
②截止阀：包装时，阀瓣应处于关闭状态。
②止回阀：包装时，升降式止回阀、蝶形止回阀和对夹立式止回阀应将阀瓣有利于关闭状态摆放；旋启式止回阀和斜瓣式止回阀的阀瓣用丁字形木条顶住，丁字形木条一端撑紧在出口端孔内，以使阀瓣在运输过程中不会碰撞。
对于外接附件如阻尼缸、气缸等，应将附件可靠小心地完全固定。
1.11阀门法兰密封面/焊接坡口/螺纹端应涂合适的防护油脂（不锈钢材质除外），阀门两端应可靠地固接木质、木纤维或塑料端以防护连接端面和阀门内部。
对于闸阀和截止阀：齿轮箱或电动装置阀门包装时须小心地安全固定，以确保齿轮箱或电动装置不会损坏并不至于穿破木箱/板条箱。
1.12包装型式应在订单中明确规定，以便安全地运输至目的地和确保安装前的保存。
1.2吊运要求1.21包装完好的阀门板条箱：用叉车进行装卸。
木箱：在木箱的重心位置处设置装吊点进行装卸。
1.22已开箱的阀门①这些阀门的吊运要采取合适的手段和措施如应用货盘进行装卸，注意应避免加工面受到损坏。
②对大尺寸阀门，在吊运阀门时可用皮带或链条绕过阀体的颈部吊起，并应保持平衡以防止意外坠落或在吊运过程中松动。
阀门手册
《阀门手册》阀门手册本书全面、系统地介绍了阀门的基础知识、阀门种类和阀门应用等方面的内容。
具体内容包括：阀门介绍、阀门选用准则、手动阀门、控制阀、手动控制器和执行机构、灵活阀门及定位器、确定阀门尺寸、确定执行机构尺寸和常见阀门问题等。
阀门手册本书可以作为阀门使用和维修人员以及设备管理和工程技术人员的工具书。
也可作为阀门设计人员和从事压力容器、管道设计人员的参考书。
阀门的定义按定义，阀门是专门设计成的机械器件用以直流、启动、停止、混合或调节工艺流体的流量、压力或温度。
阀门能设计成处理液体或气体的运行。
按阀门的设计、功能和应用的特征，它的类型、尺寸和压力等级有很多种类。
最小的工业阀门重量可小到 1 lb(0.45kg)，可舒适地放于人的手中。
而最大的可重到10t （9070kg）以上，高度达到24ft(601m)以上。
工业过程阀门能用于管线尺寸由0.5m[公称直径（DN15）]到超过48in(DN1200)。
不过超过90%以上的阀门用于工艺系统上是安装在4in(DN100)或较小尺寸的管线上。
阀门压力能够用于由负压到超过1300psi(897bar).工艺阀门尺寸的如何变化实例如图1.1所示。
今天现有阀门的淋浴已由简单的水龙头发展到备有信息处理机的控制阀，该信息处理机提供工艺过程的单环路控制。
今天最常用的类型是闸阀、旋塞阀、球阀、蝶阀、止回阀、泄压阀和截止阀。
阀门能由许多种材料制造，大多数阀门是由钢、铁、塑料、黄铜、青铜或大量的特殊合金制造的。
第二节根据功能的阀门分类1、按介质的功能设计的特征；2、双位式阀门（开－关阀门）；3、止回阀；4、节流阀；5、控制环路中的末控制元件等；按介质的功能和设计的特征阀门可分为三类：双位式（开-关式）阀门，它具有控制物流闭合和允许其通过的功能；止回阀，它只允许物流向一个方向穿流；节流阀，它可在全开到全馆的任一点上调节物流。
按功能给阀门定义的一个混乱情况是特殊的阀门设计，注入截止阀、闸阀、旋塞阀、球阀、蝶阀和胶管形阀门可符合一个、二个或所有三类分类。
CCI阀门操作手册
预热
为了避免不期望的高旁阀热震动，阀门应持久预热到流通蒸汽温度下100ºC。为保证充分预热，在主蒸汽管上安装高旁阀，到主蒸汽管的距离为DI的5-7倍（入口管内径）。若此布置不能实现，必须单独安装一段连接到阀门入口喷嘴的预热管。
图2-1：预热
若设计中包括几段源自普通管的阀门歧管，必须进行测量，以消除不期望的回声导致的入
口管中的压力震荡。
布置不良的例子：（LS =流通蒸汽管）

The material of the body and bonnet is A6063, and other metal components of the vacuumpart are made of SUS304. The sealing material of the vacuum part is FKM as standard, but this can be changed to other materials (refer to “How to Order”). Confirm whether the fluid to be used is compatible with the materials before use.Grease for vacuum is applied to the sliding part of the vacuum (Fluorine grease: Y-VAC2). 2. Select materials for the pilot pressure piping and fittings whose heat resistance is suitable forthe applicable operating temperature.●Models with auto switch1.Keep the temperature of the switch below 60oC.●With heater (thermistor)1.When using a model with a heater, a mechanism to prevent overheating should beinstalled.SelectionCaution●All models1. When controlling valve responsiveness, take note of the size and length of piping, as wellas the flow rate characteristics of the actuating solenoid valve.2. Actuating press should be kept within the specified range.0.4 MPa to 0.5 MPa isrecommended.3. Keep within the specified range of the pilot pressure.●High temperature type1. If using gases that cause a large amount of deposits, heat the valve body to prevent depositsin the valve.Mounting● All models1. In high humidity environments, keep the valve packed until the time of installation.2. For models with switches, secure the lead wires so that they have sufficient slack, withoutany unreasonable force applied to them.3. Perform piping so that excessive force is not applied to the flange sections. When there isvibration from heavy objects or attachments, etc., fix piping so that vibration will not apply torque directly to the flange section.4. Vibration resistance allows for normal operation of up to 30 m/s2 (45 to 250Hz), butcontinuous vibration may cause a decline in durability.Arrange piping to avoid excessive vibration or impacts.●High temperature type (temperature specification / H0 H4 H5)1. In models with a heater (thermistor), take care not to damage the insulation components of thelead wires and connector section.2. The set temperature for models with a heater should be established without any drafts or heat insulation. It will change depending on conditions such as heat insulation measures and the heating of other piping. Fine adjustment is not possible.3. When installing heater accessories or mounting a heater, check insulation resistance at the actual operating temperature. A current leakage breaker or fuse should be installed.4. If the valve is to be insulated, only the body should be insulated, excluding the bonnet part.5. In models with a heater, when the heater is in operation, the entire valve becomes hot. Be careful not to touch it with bare hands, as burns will result.1.Before mounting, clean the surface of the flange seal and the O-ring with ethanol, etc. 2. There is an indentation of 0.1 to 0.2mm in order to protect the flange seal surface, and it should be handled so that the seal surface is not damaged in any way.If the fluid or reaction product (deposit) may cause the valve to become unsafe, the valve should be disassembled, cleaned and re-assembled by an operator who has sufficient knowledge and experience (e.g. a specialist).1. When removing deposits from the valve, take care not to damage any part of it.2. Replace the bonnet assembly when the valve is approaching the end of its service life. * For details regarding endurance cycles, please reference Section 5 of this Operation manual titled Period and scope of warranty. (pages 10)3. If damage is suspected prior to the end of the service life, perform early maintenance.4. SMC specified parts should be used for service. Refer to the Construction / Maintenance parts table.5. When removing the valve seal and external seal, take care not to damage the sealing surfaces. When installing the valve seal and external seal, be sure that the O-ring is not twisted. (Refer to Section 6 Parts Replacement Procedure (pages 11 to 14) for details.)WarningSMC specified parts should be used for service. Refer to the construction drawing.1. Replace the bonnet assembly when changing the sealant material. Due to the differentmaterials used, changing only the seal may prove inadequate.Bonnet assembly/construction part number:1Temperature specifications IndicatorValve size16 25 40 50General use without XLF16-30-1 XLF25-30-1 XLF40-30-1 XLF50-30-1 with XLF16A-30-1 XLF25A-30-1 XLF40A-30-1 XLF50A-30-1High temperature without XLF16-30-1H XLF25-30-1H XLF40-30-1H XLF50-30-1H with XLF16A-30-1H XLF25A-30-1H XLF40A-30-1H XLF50A-30-1HTemperature specifications IndicatorValve size63 80 100 160General use without XLF63-30-1 XLF80-30-1 XLF100-30-1 XLF160-30-1 with XLF63A-30-1 XLF80A-30-1 XLF100A-30-1 XLF160A-30-1High temperature without XLF63-30-1H XLF80-30-1H XLF100-30-1H XLF160-30-1H with XLF63A-30-1H XLF80A-30-1H XLF100A-30-1H XLF160A-30-1H Note1) The magnet for auto switch is not provided.

Thesethermistors self regulate their temperature by switchingthe resistance at certain critical temperatures, so aseparate temperature controller is unnecessary.If the temperature of the PTC heaters fitted exceeds200o C, then it may fail. The maximum operatingtemperature for the valve is 150o C. If the heatertemperature is over 200o C or valve temperature is over150o C, please use thermostat to control the heaters toprevent overheating.With PTC type heaters, there is an initial surge ofcurrent (inrush current) after the power is supplied. These inrush current will reduce overtime. If multiple heater assemblies are used, the inrush current to the heaters will be magnified and care should be taken. When multiple heater assemblies or valves are used, do not apply power to the heater assemblies simultaneously. Keep approximately 30 seconds between applications of power to each heater assembly. This will allow for incremental spacing to prevent harmful large initial surge.4.hardened andnickelAAHφGBAuto switch(option)Model A B C D E Fn Fd G H XLF-16 40 103 38 1 - 30 - 17 40 XLF-25 50 113 48 1 12 40 - 26 39 XLF-40 65 158 66 2 11 55 - 41 63 XLF-50 70 170 79 2 11 75 - 52 68 XLF-63 88 196 100 3 11 87 95 70 69 XLF-80 90 235 117 3 11 114 110 83 96 XLF-100 108 300 154 3 11 134 130 102 131 XLF-160 138 315 200 3 11 190 180 153 112Unit: mmThe warranty period is 3 million cycles (for size 16, 25 and 40), 2 million cycles (for size 50, 63 and 80) or 1 million cycles (for size 100 and 160) (under SMC endurance test conditions), 18 months after delivery or 12 months in service, whichever comes first.Note ) The endurance will depend on the operating conditions (such as if the flow rate is large).

工业专用阀门手册
工业专用阀门手册一、引言概述嗨，小伙伴们！今天咱们来唠唠工业专用阀门。
你知道吗，在工业的大舞台上，阀门就像是一个个小卫士，默默地控制着各种流体的流动呢。
它们可是工业领域不可或缺的重要组成部分，没有它们，很多工业流程就没法顺利进行啦。
二、使用范围说明工业专用阀门的使用范围那可广了去了。
在石油化工行业，那些管道里流淌着原油、各种化工原料的时候，阀门就负责控制这些原料的流量，该关就关，该开就开。
在水处理厂也少不了它们，不管是净化水的流入流出，还是污水的处理过程，阀门都在精确地把控着水流的节奏。
还有发电厂，蒸汽啊、冷却水啊之类的流体在管道里穿梭，阀门就是确保这些流体按照正确的路径和量来运行的关键。
三、操作步骤指南1. 手动阀门操作首先呢，你得找到阀门的操作手柄或者手轮。
一般来说，顺时针旋转手轮是关闭阀门，就像拧紧螺丝一样，而逆时针旋转呢就是打开阀门啦。
在操作的时候，要平稳用力，可不能猛转，不然可能会损坏阀门内部的结构哦。
对于一些比较大的手动阀门，可能需要两个人配合操作，一个人负责固定住阀门的主体，防止在操作过程中晃动，另一个人来转动手轮。
2. 电动阀门操作在操作电动阀门之前，要先检查电气连接是否正常。
看看电线有没有破损，插头有没有插好。
然后呢，找到电动阀门的控制箱。
控制箱上一般有开、关、停这几个按钮。
按“开”按钮的时候，阀门就会慢慢打开，你可以通过观察阀门上的开度指示器，或者连接的监控设备来查看阀门的开启程度。
要关闭阀门就按“关”按钮，同样要注意观察。
如果在操作过程中出现异常情况，赶紧按“停”按钮，让阀门停止动作。
3. 气动阀门操作气动阀门是靠气体压力来驱动的。
首先要确保气源的压力是正常的，一般在操作面板上会有气源压力的显示。
然后找到气动阀门的控制旋钮或者按钮，按照标识来操作。
比如有的是向上推是开，向下拉是关。
在操作的时候，要注意听阀门动作的声音，如果有异常的嘶嘶声或者咔咔声，可能是阀门内部有问题了。
四、功能特点介绍1. 密封性好工业专用阀门的密封性可是它的一大亮点。
