水流指示器安裝在保護區內的噴淋管上，監測水流動作。一旦發生火災，噴頭會因溫度過高而爆裂。此時，管道內的水會流向爆裂的噴頭，流動的水力力量會推動水流指示器的作用(管道內也放置橡膠葉片)。水流指示器起水流監測的作用，不與其他設備連接。
The water flow indicator is installed on the spray pipe in the protection area to monitor the action of water flow. In case of fire, the nozzle will burst due to excessive temperature. At this time, the water in the pipe will flow to the burst nozzle, and the flowing hydraulic force will promote the function of the water flow indicator (rubber blades are also placed in the pipe). The water flow indicator plays the role of water flow monitoring and is not connected with other equipment.
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。
The blade of the water flow indicator is perpendicular to the water flow direction. After the nozzle is opened, the water in the pipeline flows. When the blade or diaphragm senses the force of the water flow, it drives the microswitch to act, connects the delay line, and the delay device 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 electrical 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.
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。水流指示器的功能，是及時報告發生火災的部位。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。水流指示器的大工作壓力為1.2MPa。具有延遲功能的水流指示器延遲時間為2~90s。水
The water flow indicator is generally applicable to wet, dry, pre action, circulating open close, automatic water spray foam combined system. The function of the water flow indicator is to report the location of the fire in time. 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. The large working pressure of the water flow indicator is 1.2MPa. The delay time of the water flow indicator with delay function is 2 ~ 90s. water
水流指示器的檢查要求要求了解，比如銘牌清晰、有操作指示標識和產品說明書。有水流方向的性標識。各組件不得有機構松動、明顯的加工缺陷，表面不得有明顯銹蝕、圖層剝落、起泡、毛刺等缺陷；水流指示器槳片完好。等等。
The inspection requirements of water flow indicator shall be understood, such as clear nameplate, safe operation indication mark and product manual. There is a permanent sign of the direction of water flow. All components shall be free from loose mechanism, obvious processing defects, and the surface shall be free from obvious corrosion, layer peeling, blistering, burr and other defects; The paddles of the water flow indicator are intact. wait.
為使系統維修時關停的范圍不致過大而在水流指示器入口前設置閥門時，要求該閥門采用信號閥，以便顯示閥門的狀態，其目的是為了防止因誤操作而造成配水管道斷水的故障。當1只噴頭啟動或從末端試水裝置處放水時，水流指示器應有信號返回消防控制中心。
In order to prevent the shutdown range during system maintenance from being too large, when a valve is set in front of the inlet of the water flow indicator, the valve is required to adopt a signal valve to display the status of the valve. Its purpose is to prevent the failure of water cut-off of the water distribution pipeline due to misoperation. When one sprinkler starts or discharges water from the end water test device, the water flow indicator shall have a signal to return to the fire control center.
川消水流指示器不動作或信號不正常，可能是由于槳片被管腔內雜物堵塞，調整螺母與觸頭未調整到位或電路接線脫落造成的，應采取相應的合理措施排除故障，如水流指示器管腔內的雜物，將調整螺母與觸頭調整到位，檢查并重新將脫落電路接通等。
The failure or abnormal signal of Chuanxiao water flow indicator may be caused by the blockage of the paddle by the sundries in the lumen, the failure to adjust the adjusting nut and contact in place or the falling off of the circuit wiring. Corresponding reasonable measures shall be taken to eliminate the fault, such as removing the sundries in the lumen of the water flow indicator, adjusting the adjusting nut and contact in place, checking and reconnecting the falling off circuit, etc.
不同場所，不同防火等級以及不同樓層數的建筑單位，對于水流指示器安裝的數量要求各有不同，所以使用時要具體情況具體選擇。那么如果您想了解更多內容就來川消網站
