水流指示器属视镜类仪表阀门其适用于石油、化工、化纤、医药、食品、电厂、泵等工业生产管路中，通过视窗能随时观察液体、气体、蒸汽等介质的浑浊度且计量介质流动速度反应情况，是保障正常生产保证产品质量不可缺少的管道附件之一。那么他的作用和安装是怎样的呢？下面川消小编为您讲解：

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

水流指示器的主要应用就是应用在消防的自动灭水的系统之中，在自动灭水系统中水流指示器发挥着重要的作用。

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.

它有的是安装在主供水管上，有的是安装在横杆水管上，它可以在灭水系统工作的时候给出某一个分区的球的水流动的电信号，这个电信号可以经过一定的作用到达电控箱，那么到达电控箱之后相应的系统就会给出反应，这样就可以实现启动消防水泵的控制开关，另外也可以实现检测和指示警报的作用。

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.

水流指示器安装使用注意事项

Precautions for installation and use of water flow indicators

1、水流指示器应水平安装于系统管路上，不应侧装或是倒装，以防影响水流指示器灵敏度。

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、连接水流指示器的管路必需保证其前后直管长度不小于管路直径的5倍，选用水流指示器时应根据管路公称直径按技术参数表对应选择。

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、安装是应注意水流方向，切开不可方向安装。

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、水流指示器出厂时延迟时间可调整，调整范围为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.
