一、闸阀靠阀板的上下移动，控制阀门开度。
阀板象是一道闸门。
闸阀关闭时，密封面可以只依靠介质压力来密封，即只依靠介质压力将闸板的密封面压向另一侧的阀座来保证密封面的密封，这就是自密封。
大部分闸阀是采用强制密封的，即阀门关闭时，要依靠外力强行将闸板压向阀座，以保证密封面的密封性。
闸阀的种类,按密封面配置可分为楔式闸板式闸阀和平行闸板式闸阀, 楔式闸板式闸阀又可分为: 单闸板式、双闸板式和弹性闸板式；平行闸板式闸阀可分为单闸板式和双闸板式。
按阀杆的螺纹位置划分，可分为明杆闸阀和暗杆闸阀两种。
国内生产闸阀的厂家比较多，连接尺寸也大多不统一。
性能特点：优点：1、流动阻力小。
阀体内部介质通道是直通的，介质成直线流动，流动阻力小。
2、启闭时较省力。
是与截止阀相比而言，因为无论是开或闭，闸板运动方向均与介质流动方向相垂直。
3、高度大，启闭时间长。
闸板的启闭行程较大，降是通过螺杆进行的。
4、水锤现象不易产生。
原因是关闭时间长。
5、介质可向两侧任意方向流动，易于安装。
闸阀通道两侧是对称的。
6、结构长度(系壳体两连接端面之间的距离)较小。
7、形体简单, 结构长度短，制造工艺性好，适用范围广。
8、结构紧凑，阀门刚性好，通道流畅，流阻数小，密封面采用不锈钢和硬质合金，使用寿命长，采用PTFE 填料．密封可靠．操作轻便灵活．缺点：密封面之间易引起冲蚀和擦伤，维修比较困难。
外形尺寸较大，开启需要一定的空间，开闭时间长。
结构较复杂。

As a result, the diaphragm is pushed back by the spring and the valve opens, allowing more gas in from the supply until equilibrium is reached between the outlet pressure and the spring.The outlet pressure is a function of the spring force which may be modified by the adjustment knob. The outlet pressure and the inlet pressure hold the quad ring poppet assembly in the closed position against the force of the spring.56 threads/in.

GP系列电子压力调节器说明书
GP1/GP2 INSTALLATION & MAINTENANCE INSTRUCTIONSDESCRIPTION / IDENTIFICATIONThe GP series control valve is an electronic pressure regu-lator designed to precisely control the pressure of gaseous media proportional to an electronic signal.The GP1 operates using two normally closed solenoid valves, a pressure sensor, and a control circuit. One valve is actuated to allow unregulated supply media into the sys-tem. The second valve is actuated to allow working media to vent to atmosphere. The pressure sensor provides feed-back to the control circuit. The control circuit comparesthe pressure sensor feedback to the user supplied electronic command signal and actuates the appropriate valve until the two signals match.The GP series can be teamed with a variety of one-to-one ratio high pressure volume boosters for even greater flow. When using a volume booster, the GP2 can be used toachieve accuracy similar to the GP1 alone with higher flow capacity.GP series product comes with a monitor output signal. This output is an electrical signal originating from the inter-nal sensor used in the control circuit of the GP1 valve. On GP2 units this signal originates from the external trans-ducer. This allows the system parameters to be monitored and provides a signal for data acquisition needs.The output of this signal can be configured to either 0-10Vdc or 4-20mA.The GP2 is similar to the GP1 but uses a double loop con-trol scheme. In addition to the internal pressure transducer, the GP2 also receives a 0-10Vdc feedback signal from an external sensing device. The external signal functions as the primary feedback and is compared to the command sig-nal. A difference between the two comparisons causes one of the two solenoid valves to open allowing flow in or out of the system.A Proportion-Air DSY or DSTY will work as a second loop feedback to the GP2 (See ordering information).The GP series has several other beneficial features. An on board split power supply allows true zero for command and monitor even though the GP is powered by a conventional single ended power supply. The GP utilizes advanced on board power management hardware to minimize current draw and heat build up. The GP also features status indi-cating LEDs for power and TTL. The TTL signal is a con-ditional on/off signal to use for diagnostic purposes. This signal is LOW when the pressure is within 1% of final set-ting.• Description & identification • General specifications • Connection procedure • Re-calibration procedure • Repair procedure•Dimensions, ordering and accessoriesBefore you get started, please read these warnings:♦ Examine the product.

38张阀门动图-工作状态和原理一目了然!
38张阀门动图-工作状态和原理一目了然!38张阀门动图工作状态和原理一目了然！2016-05-25 11:08小七导读：液压阀是一种用压力油操作的自动化元件，它受配压阀压力油的控制，通常与电磁配压阀组合使用，可用于远距离控制水电站油、气、水管路系统的通断。
今天，小七为大家配上动图来介绍各种液压阀的原理和功能！按控制方法分类：手动，电控，液控按功能分类：流量阀（节流阀、调速阀，分流集流阀）、压力阀（溢流阀，减压阀，顺序阀，卸荷阀）、方向阀（电磁换向阀、手动换向阀、单向阀、液控单向阀）◆◆◆单向阀单向阀是流体只能沿进水口流动，出水口介质却无法回流，俗称单向阀。
单向阀又称止回阀或逆止阀。
用于液压系统中防止油流反向流动,或者用于气动系统中防止压缩空气逆向流动。
安装止回阀时，应特别注意介质流动方向，应使介质正常流动方向与阀体上指示的箭头方向相一致，否则就会截断介质的正常流动。
底阀应安装在水泵吸水管路的底端。
止回阀关闭时，会在管路中产生水锤压力，严重时会导致阀门、管路或设备的损坏，尤其对于大口管路或高压管路，故应引起止回阀选用者的高度注意。
单向阀有控制油时+换向阀换向阀是具有两种以上流动形式和两个以上油口的方向控制阀。
是实现液压油流的沟通、切断和换向，以及压力卸载和顺序动作控制的阀门。
这种变换阀在石油、化工生产中有着广泛的应用，在合成氨造气系统中最为常用。
此外，换向阀还可作成阀瓣式的结构，多用于较小流量的场合。
工作时只需转动手轮通过阀瓣来变换工作流体的流向。
◆◆◆换向阀-二位二通二位即表示阀芯工作在两种状态下，线圈不通电时阀芯在一个位置，通电时运动到另一个位置，通过位置的变换来切换阀的导通状态；二通的意思是阀有两个接口（一进一出）。
二位二通阀实际上就是一个截止阀，起关断/打开管路的目的，没有换向的功能。
+◆◆◆换向阀-二位四通二位四通换向阀适用干油或稀油集中润滑系统,以转换供油方向或开闭供油管道。
此换向阀采用大扭矩直流减速电机驱动换向，因此即使在恶劣的工况下（如低温或粘度很高的润滑脂），换向动作也十分可靠。

C．主膜片的拆卸
1．拆下固定膜片上 / 下盖（4）/（5）的全部螺栓（41）。 2．分开上下盖后，取下主膜片（12）、固定环（11）和主阀杆（9）。
组装
1．检查并确保主阀瓣、阀座或先导阀瓣上无划痕。如果发现划痕，则用研磨剂重新研磨阀瓣和阀座。 2．确保活动部件（先导阀阀杆和主阀阀杆）能够活动自如。 3．应在主膜片上和先导膜片的底部使用垫片抗咬合剂。 4．按照与拆卸减压阀相反的顺序进行减压阀的组装。 5．用匀力拧紧螺栓（十字形）。 6．检查新旧铜管保证正确的安装。 7．确保接头（30A）/（30B）/（30C）和三通（33）安装在正确的位置上，没有被过度拧紧。参考图3-1。 8．确定先导阀铜垫片（22）和主阀座垫片（8）就位后，拧紧先导阀组件和主阀座。

调速阀
调速阀实际上是一种进行了压力补偿的节流阀。它由定差 减压阀和节流阀串联而成，由减压阀的自动平衡作用来进行压 力补偿，使节流口前后压差△p基本保持恒定，从而稳定所通过 的流量。
