Water control valve is a water pressure control valve. Water control valve is composed of a main valve and conduit, ball valve, pressure gauge, etc. so how to install water control valve? What is the principle structure? Then follow the Xiaobian of Shanghai Valve agent to have a look!

一、水利控制阀安装

1、 Installation of hydraulic control valve

水平安装时,阀盖宜向上.消防给水系统的减压阀阀后应有排水设施.自动喷水灭火系统的需减压时,减压阀应设置在警声阀前(沿水流方向),与单个警声阀配套设置的减压阀,可不设备用减压阀;与多个警声阀配套设置的减压阀,应设备厂用减压阀.用于热水供应工程的减压阀,应采用热水型减压阀.

When installed horizontally, the valve cover should be upward. There should be drainage facilities behind the pressure reducing valve of the fire water supply system. When the pressure of the automatic sprinkler system needs to be reduced, the pressure reducing valve should be set in front of the alarm valve (along the water flow direction). The pressure reducing valve matched with a single alarm valve may not be used for the equipment; The pressure reducing valve matched with multiple alarm valves shall be the plant pressure reducing valve of the equipment. The pressure reducing valve used for hot water supply project shall be the hot water type pressure reducing valve

二、水利控制阀原理构造

2、 Principle and structure of hydraulic control valve

遥控浮球阀应设置在水池或水箱的进水管道上,宜水平安装,阀盖朝上.其控制导管与浮球设置应符合以下要求:

The remote control float valve shall be set on the water inlet pipe of the pool or water tank, which shall be installed horizontally with the valve cover facing upward. The setting of its control conduit and float ball shall meet the following requirements:

水利控制阀是以管道介质压力为动力,进行启闭、调节的阀门.它由一个主阀和附设的导管、针阀、球阀和压力表等组成、根据使用的目的、功能场所的不同,可演变成遥控浮球阀、减压阀、缓闭止回阀、流量控制器、泄压阀、水力电动控制阀、紧急关闭阀等.导阀随介质的液位和压力的变化而动作。

Hydraulic control valve is a valve for opening, closing and regulating with pipeline medium pressure as power. It is composed of a main valve and attached conduit, needle valve, ball valve and pressure gauge. According to the purpose of use and different functional places, it can be evolved into remote control float valve, pressure reducing valve, slow closing check valve, flow controller, pressure relief valve, hydraulic electric control valve Emergency shut-off valve, etc. the pilot valve acts with the change of medium liquid level and pressure.

由于导阀种类很多,可以单独使用或几个组合使用,就可以使主阀获得对水位和水压及流量等进行单独和复合调节的功能.但主阀阀体类似截止阀,阀门全开时,其压力损失比其他阀门要大得多,且各个开度损失系数越是与全闭状态接近,越是剧增,阀门口径越大就越显著.

Due to many types of pilot valves, they can be used alone or in combination, so that the main valve can obtain the function of independent and composite regulation of water level, water pressure and flow. However, the main valve body is similar to a stop valve. When the valve is fully open, its pressure loss is much greater than that of other valves, and the closer the loss coefficient of each opening is to the fully closed state, the more sharp the increase is, and the larger the valve diameter is, the more significant it is
