水流指示器屬視鏡類儀表閥門其適用于石油、化工、化纖、醫藥、食品、電廠、泵等工業生產管路中，通過視窗能隨時觀察液體、氣體、蒸汽等介質的渾濁度且計量介質流動速度反應情況，是保障正常生產保證產品質量不可缺少的管道附件之一。那么他的作用和安裝是怎樣的呢？下面川消小編為您講解：

The water flow indicator belongs to the mirror type instrument valve, which is suitable for industrial production pipelines such as petroleum, chemical industry, chemical fiber, medicine, food, power plants, pumps, etc. Through the window, the turbidity of liquid, gas, steam, and other media can be observed at any time, and the flow rate reaction of the measuring medium can be measured. It is one of the indispensable pipeline accessories to ensure normal production and product quality. So what is its role and installation? Below, the editor of Chuanxiao will explain to you:

水流指示器的作用

The function of the water flow indicator

水流指示器的主要應用就是應用在消防的自動滅水的系統之中，在自動滅水系統中水流指示器發揮著重要的作用。

The main application of water flow indicators is in the automatic water extinguishing system of fire protection, where water flow indicators play an important role.

它有的是安裝在主供水管上，有的是安裝在橫桿水管上，它可以在滅水系統工作的時候給出某一個分區的球的水流動的電信號，這個電信號可以經過一定的作用到達電控箱，那么到達電控箱之后相應的系統就會給出反應，這樣就可以實現啟動消防水泵的控制開關，另外也可以實現檢測和指示警報的作用。

Some of them are installed on the main water supply pipe, while others are installed on the crossbar water pipe. It can provide an electrical signal of the water flow of a certain zone's ball when the water extinguishing system is working. This electrical signal can be used to reach the electric control box, and after reaching the electric control box, the corresponding system will respond, which can achieve the control switch of starting the fire water pump, In addition, it can also achieve the function of detecting and indicating alarms.

水流指示器安裝使用注意事項

Precautions for installation and use of water flow indicators

1、水流指示器應水平安裝于系統管路上，不應側裝或是倒裝，以防影響水流指示器靈敏度。

1. The water flow indicator should be installed horizontally on the system pipeline and should not be installed sideways or upside down to prevent affecting the sensitivity of the water flow indicator.

2、連接水流指示器的管路必需保證其前后直管長度不小于管路直徑的5倍，選用水流指示器時應根據管路公稱直徑按技術參數表對應選擇。

2. The pipeline connecting the water flow indicator must ensure that the length of the front and rear straight pipes is not less than 5 times the diameter of the pipeline. When selecting the water flow indicator, it should be selected according to the nominal diameter of the pipeline and the technical parameter table.

3、安裝是應注意水流方向，切開不可方向安裝。

3. Attention should be paid to the direction of water flow during installation, and installation should not be carried out in the direction of cutting.

4、水流指示器出廠時延遲時間可調整，調整范圍為2-90s。

4. The delay time of the water flow indicator can be adjusted at the factory, with an adjustment range of 2-90 seconds.
