阀门

SPECIFY: Valve mounted pilot is required, and valve discharge horizontal or vertical.

指定： 如果需要，可以在阀门上安装引导装置，阀门也可水平或垂直排放。

As a downstream piping system when the valve opens, reflux valve, when closed, the main medium used to prevent backflow to prevent the pump and drive motor reversal, as well as a container medium discharge; currently the most commonly used is the valve flap around the body Swing Pin rotation flap valve and the valve body along the vertical axis to move lift check valve, but the above two kinds of structures exist in the valve closed, medium speed back quickly from the largest drop to zero, inlet side of the pipe resulted in the rapid pressure rise, resulting Proportional Pressure Reducing Valves in damaging effects on the piping system of water hammer phenomenon, it is generally a diameter of valve production of 50 ~ 500 mm.

止回阀作为管道系统顺流时开启，逆流时关闭的阀门，主要用于防止介质倒流，防止泵及驱动电机反转以及容器内介质泄放；目前使用最普遍的是阀瓣围绕阀体销轴旋转的旋启式止回阀和阀瓣沿着阀体垂直中心线移动的升降式止回阀，但以上2种结构的阀门均存在关闭时介质倒流速度从最大迅速降为零，致使管道进水管一侧内压迅速升高，从而产生对管路系统有破坏作用的水锤现象，所以一般止回阀生产口径为50～500 mm。

In doing so, I learned that by opening a small panel door just above the pump panel, you could gain access to the control valve and that removing a small pin from the point where the valve handle connected to the motor, you would then be able to operate the valve by hand.

这样做，我知道了打开水泵正上方面板的小面板门，你可以进入控制阀，并剔除了点小针在阀门手柄连接到汽车，你便可以为手工操作阀门。

I is the production of various kinds of high pressure valve in one of the professional manufacturers, with many years of operating history and production of valves.

我公司是生产各类高、中压阀门的专业厂家之一，具有多年的阀门生产和经营历史。

The strength of the valve is the valve under media pressure capacity.

阀门的强度性能是指阀门承受介质压力的能力。

Valves open and close speeds generally no strict requirements, but some conditions the speed of the hoist he special requirements, if any, the prompt to open or PRESSURE-REDUCING VALVE EN200X closed, to prevent an accident, and some require slow and shut down to prevent the resulting water hammer, etc.

一般对阀门的启闭速度无严格要求，但有些工况对启闭速度有特殊要求，如有的要求迅速开启或关闭，以防发生事故，有的要求缓慢关闭，以防产生水击等，这在选用阀门类型时应加以考虑。
