水流指示器做為觀察管道的必要附件，隨時監控液體的流動速度。信號閥和水流指示器對消防救援關重要，是消防管道的必要部件，不可或缺。下面
川消小編為您講解下相關的作用。
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。其連接方式包括螺紋式、法蘭式、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動噴水滅火系統，它可以安裝在主供水管或橫桿水管上，給出某一分區域小區域水流動的電信號，此電信號可送到電控箱，但通常不用作啟動消防水泵的控制開關。
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.
水流指示器也可用于自動噴水滅火系統，它可以安裝在主供水管或橫干管上，給出某一分區域小區域水流動的電信號，此電信號可送到電控箱，但通常不用作啟動消防水泵的控制開關。
The water flow indicator can also be used in the automatic sprinkler system. It can be installed on the main water supply pipe or the horizontal main 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.
信號閥連線消防控制中心，信號閥反饋該閥門開或閉狀態，水流指示器作用是反饋該管段水流動靜止或狀態消防中心一般用紅綠2色對應指示燈表現。
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.
信號閥結構特點及工作原理：該蝶閥的電信號裝置設計蝸桿、蝸輪驅動裝置的頂部，并與閥桿直聯傳動，在全封閉的機電裝置內，設有閥門開啟度機械指示和進口電氣元件及防銹機件。輸出信號長期穩定可靠。
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.
閥門有個電節點，用信號線引出消控中心，信號線電壓12v。其實就是閥門開啟、關閉，有信號傳到消控中心，便于監控，閥門除了有電節點外，跟普通閥門沒有多少區別，也有信號蝶閥。
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.
信號閥缺失或者被誤動作關閉時，一旦發生火災，現場無法達到滅火要求；而水流指示器作為監控水流的部件，在日常保養中及時查看管道內部水流量來確保發生火災時能夠有足夠的水達到滅火要求。更多相關事項就來我們網站

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.
