手压阀说明书

手动阀门使用说明
手动阀门是常用的阀门之一，包括有手动蝶阀、手动闸阀、手动球阀、手动截止阀等等，本文为您介绍一下手动阀门使用说明。

1、手动阀门的操作需要操纵阀门的人员握住手柄或手轮进行操作，不能够借助杠杆和长扳手来开关阀门，避免用力过猛对手柄或手轮造成损坏，更不能暴力操作，避免事故发生。

通常情况下，手柄的长度或手轮的直径小于320mm，只允许单人进行操作；手轮的直径等于或大于320mm时，允许两个人共同操作完成，也可以单人适当借助工具，杠杆或扳手进行操作，但要注意杠杆长度不可超过0.5m。

2、手动闸阀和手动截止阀都是借助手轮进行操作，在阀门完全开启或关闭之后，要回转1/4~1/2圈，让螺纹之间更好的密合，同时也能避免阀门拧得过紧出现损坏。

3、操作手动蒸汽阀门，在开启前要先对管道进行预热，排出管道中的凝聚水；开启阀门的速度要慢，以防水锤现象的发生，对阀门和管道设备造成损坏。

4、常开的手动阀门密封面上，很容易粘上杂质和脏物，在关闭闭合之前，微微开启一条缝，可以让高速流动的介质冲走这些异物，然后再轻轻关闭，提高密封效果。

5、在一些过高温介质的管道中，当手动阀门关闭之后，阀体内温度下降，因为热胀冷缩导致阀件收缩，密封面会出现一些细小的缝隙，阀门会出现泄漏。

在这种情况下，要在关闭手动阀门之后，过一会儿再关闭一次。

“MP-4”MANUAL RELAYMODEL 1901OPERATION MANUAL OMP # 1901 08/02 Revision 0I. PRINCIPLE OF OPERATIONThe Ruelco “MP-4” relay is a pilot operated manual relay. It is a three (3) way, normally closed valve with a palm knob for relay position indication and manual operation. In the closed position, pneumatic or hydraulic pressure coming into the “Inlet” port is locked from the “Outlet” port by the upper shaft o-ring. The spring keeps the spool in the down or closed position. The valve is opened by manually pulling the palm knob outward, thus moving the shaft assembly upward. The detent pin is then pushed “In” to lock the relay open until a pneumatic signal is applied to the pilot cap of the relay. This pneumatic pressure acting on the piston causes the detent pin to drop “Out” of the locked position. When the relay is in the open position, it causes the middle o-ring to engage the body seal bore and the upper o-ring to disengage from the body seal bore respectively. Supply pressure at the “Inlet” port may then flow through the body to the “Outlet” port.When the pneumatic signal is removed from the pilot supply “PS”, the spring moves the shaft assembly downward. This causes the upper O-ring to disengage the body seal bore. This also allows the middle O-ring to engage the body seal bore and prevent flow into the “IN” port. With the supply pressure blocked, pressure will flow from the “OUT” port and exit through the “VENT” port. The relay may also be closed manually by pushing the palm knob inward.II. INSTALLATIONThe “MP-4” can be mounted either vertically, horizontally, panel mounted (with optional panel mount nut), or supported by piping from any of its ports. If it is supported by piping, care should be taken that the strength of the pipe fittings used is adequate to prevent the fitting from breaking off in the relay body should the relay be inadvertently struck.Proper pipe thread sealant should be used on any pipe fittings threaded into the relay ports. If stainless steel fittings are used, a sealant that will prevent galling is required. Supply gas or hydraulic fluid flowing through the relay should be free of large dirt particles. If compressed air is used, it does not have to be lubricated. If natural gas is used, it should contain as little condensate as possible. This will extend the life of the seals.If the relay is going to be installed in a location where the stem will be exposed to excessive paint, sand, drilling fluids, etc., the use of the optional stem protector is recommended. The stem protector does not affect the operation of the relay and will prevent the relay from jamming should the exposed portion of the shaft accumulate excessive trash or debris.III. DISASSEMBLY (REFER TO SPEC.SHEET 1901)Tools required are as follows:• 7/16” open end wrench or suitable adjustable wrench•1” open end wrench or suitable adjustable wrench•7/8” open end wrench or suitableadjustable wrench and flat bladescrew driver (for removal ofoptional stem protector)A.

手压阀设计
一、工作原理
手压阀是开启或关闭液路的一种手动阀门。

手柄向下压紧阀杆时，弹簧受压，阀杆向下移动，使入口和出口相通，阀门打开；松开手柄，因弹簧力作用，阀杆向上压紧阀体，入口与出口不通，阀门关闭。

二、机构功能
手压阀用来控制流体的方向、压力、流量的装置。

阀门是使配管和设备内的介质液体、流动或停止、并能控制其流量的装置。

主要用于手动改变压力大小，从而达到手动变速的目的。
