水利控制閥如何安裝?原理構造是什么?

水利控制閥就是水壓控制的閥門,水利控制閥是由一個主閥和導管、球閥、壓力表等組成的那么水利控制閥該如何安裝呢?原理構造又是什么呢?那就跟著上海閥門代理的小編一起來看看吧!
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、水利控制閥安裝
1、 Installation of hydraulic control valve
水平安裝時,閥蓋宜向上.消防給水系統(tǒng)的減壓閥閥后應有排水設施.自動噴水滅火系統(tǒng)的需減壓時,減壓閥應設置在警聲閥前(沿水流方向),與單個警聲閥配套設置的減壓閥,可不設備用減壓閥;與多個警聲閥配套設置的減壓閥,應設備廠用減壓閥.用于熱水供應工程的減壓閥,應采用熱水型減壓閥.
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、水利控制閥原理構造
2、 Principle and structure of hydraulic control valve
遙控浮球閥應設置在水池或水箱的進水管道上,宜水平安裝,閥蓋朝上.其控制導管與浮球設置應符合以下要求:
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:
水利控制閥是以管道介質壓力為動力,進行啟閉、調節(jié)的閥門.它由一個主閥和附設的導管、針閥、球閥和壓力表等組成、根據使用的目的、功能場所的不同,可演變成遙控浮球閥、減壓閥、緩閉止回閥、流量控制器、泄壓閥、水力電動控制閥、緊急關閉閥等.導閥隨介質的液位和壓力的變化而動作。
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.
由于導閥種類很多,可以單獨使用或幾個組合使用,就可以使主閥獲得對水位和水壓及流量等進行單獨和復合調節(jié)的功能.但主閥閥體類似截止閥,閥門全開時,其壓力損失比其他閥門要大得多,且各個開度損失系數越是與全閉狀態(tài)接近,越是劇增,閥門口徑越大就越顯著.
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
