水流指示器的葉片與水流方向垂直，噴頭開啟后引起管道中的水流動，當槳片或膜片感知水流的作用力時帶動微動開關動作，接通延時線路，延時器開始計時。到達設定的延時時間后，葉片仍向水流方向偏轉無法回位，電觸點閉合，輸出信號。當水流停止時，槳片和動作桿復位，觸點斷開，信號。下面來講講水流指示器設置和安裝要求。
The blade of the water flow indicator is perpendicular to the direction of water flow. After the nozzle is opened, the water in the pipe flows. When the paddle or diaphragm senses the force of water flow, it drives the microswitch to act, connects the delay line, and the time delayer starts timing. After reaching the set delay time, the blade still deflects in the direction of water flow and cannot return to its position. The electric contact is closed and the signal is output. When the water flow stops, the paddle and actuating rod are reset, the contact is disconnected, and the signal is eliminated. Now let's talk about the setting and installation requirements of water flow indicator.
1.水流指示器的功能，是及時報告發生火災的部位。
1. The function of the water flow indicator is to report the fire site in time.
2.信號閥安裝在水流指示器前的管道上，與水流指示器間的距離不宜小于300mm。
2. The signal valve shall be installed on the pipeline in front of the water flow indicator, and the distance between the signal valve and the water flow indicator shall not be less than 300mm.
3.水流指示器的大工作壓力為1.2MPa。
3. The large working pressure of the water flow indicator is 1.2MPa.
4.具有延遲功能的水流指示器延遲時間為2~90s。
4. The delay time of the water flow indicator with delay function is 2~90s.
5.水流指示器一般適用于濕式、干式、預作用、循環啟閉式、自動噴水—泡沫聯用系統中。
5. The water flow indicator is generally applicable to wet, dry, pre acting, circulating open close, automatic water spray foam combined system.
6.可不設置情況：
6. Optional:
當一個濕式報警閥組僅控制一個防火分區或一個層面的噴頭時。由于報警閥組的水力警鈴和壓力開關已能發揮報告火災部位的作用，故此種情況允許不設水流指示器。
When a wet alarm valve group only controls the sprinkler of one fire compartment or one layer. Since the hydraulic alarm bell and pressure switch of the alarm valve group can play the role of reporting the fire position, it is allowed not to set a water flow indicator in this case.
僅用于保護鋼屋架、桁架而獨立設置的報警閥，水流指示器所起到的報警作用有限，可考慮不安裝水流指示器。
The independent alarm valve is only used to protect the steel roof truss and truss, and the water flow indicator has limited alarm effect, so it can be considered not to install the water flow indicator.
That's all for the setting and installation requirements of Chuanxiao water flow indicator. If you don't want to be prone to faults, you should be prepared in advance. Whether it's usage precautions or fault problems, more matters can be found on the website http://m.xintli.net Consult.
