水流指示器做为观察管道的必要附件，随时监控液体的流动速度。信号阀和水流指示器对消防救援关重要，是消防管道的必要部件，不可或缺。下面川消小编为您讲解下相关的作用。

As a necessary accessory for observing the pipeline, the water flow indicator can monitor the liquid flow speed at any time. The signal valve and water flow indicator are essential to fire rescue and are necessary components of fire pipeline. Now let's talk about the role of Chuanxiao.

水流指示器能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。其连接方式包括螺纹式、法兰式、焊接式。

The water flow indicator can observe the turbidity of liquid, gas, steam and other media at any time through the window and measure the reaction of the media flow rate. It is one of the indispensable pipe accessories to ensure normal production and product quality. The connection modes include threaded type, flange type and welding type.

水流指示器也可用于自动喷水灭火系统，它可以安装在主供水管或横杆水管上，给出某一分区域小区域水流动的电信号，此电信号可送到电控箱，但通常不用作启动消防水泵的控制开关。

The water flow indicator can also be used in the automatic sprinkler system. It can be installed on the main water supply pipe or cross bar water pipe to give the electrical signal of water flow in a small area of a certain subregion. This electrical signal can be sent to the electric cabinet, but it is usually not used as the control switch to start the fire pump.

信号阀连线消防控制中心，信号阀反馈该阀门开或闭状态，水流指示器作用是反馈该管段水流动静止或状态消防中心一般用红绿2色对应指示灯表现。

The signal valve is connected to the fire control center. The signal valve feeds back the open or closed state of the valve. The water flow indicator is used to feed back the static or dynamic state of the water flow in the pipe section. The fire control center generally uses red and green corresponding indicator lights.

信号阀结构特点及工作原理：该蝶阀的电信号装置设计蜗杆、蜗轮驱动装置的顶部，并与阀杆直联传动，在全封闭的机电装置内，设有阀门开启度机械指示和进口电气元件及防锈机件。输出信号长期稳定可靠。

Structural characteristics and working principle of the signal valve: the electric signal device of the butterfly valve is designed on the top of the worm and worm gear drive device, and is directly connected with the valve stem for transmission. In the fully enclosed electromechanical device, there is a mechanical indication of valve opening, imported electrical components and anti rust parts. The output signal is stable and reliable for a long time.

阀门有个电节点，用信号线引出消控中心，信号线电压12v。其实就是阀门开启、关闭，有信号传到消控中心，便于监控，阀门除了有电节点外，跟普通阀门没有多少区别，也有信号蝶阀。

The valve has an electrical node, which is led out to the fire control center with a signal line voltage of 12v. In fact, when the valve is opened and closed, a signal is sent to the fire control center to facilitate monitoring. Except for the electric node, the valve is not much different from the ordinary valve, and there is also a signal butterfly valve.

信号阀缺失或者被误动作关闭时，一旦发生火灾，现场无法达到灭火要求；而水流指示器作为监控水流的部件，在日常保养中及时查看管道内部水流量来确保发生火灾时能够有足够的水达到灭火要求。更多相关事项就来我们网站http://www.cx-fire.com咨询！

When the signal valve is missing or closed by mistake, once a fire occurs, the site cannot meet the fire extinguishing requirements; As a component for monitoring water flow, the water flow indicator shall check the water flow in the pipeline in time during daily maintenance to ensure that there is enough water to meet the fire extinguishing requirements in case of fire.
