在現代消防工程中，在濕式報警閥和水流指示器供水側應采用信號蝶閥。因此，消防信號蝶閥的用途越來越顯得廣泛。
川消消防信號蝶閥沒有信號或信號長報是怎么回事？
In modern fire protection engineering, it is recommended to use signal butterfly valve at the water supply side of wet alarm valve and water flow indicator. Therefore, the fire signal butterfly valve is more and more widely used. What's wrong with Chuanxiao fire signal butterfly valve without signal or long signal alarm?
1消防信號蝶閥的信號是靠微動開關觸點的通斷原理來實現的。由微動開關本身質量問題而引起的信號蝶閥故障可能發生，但不合格產品的概率很低，要判斷是不是微動開關的質量問題，簡單的方法就是用萬用表測量，看微動開關電阻值的變化。
1 the signal of fire signal butterfly valve is realized by the on-off principle of microswitch contact. The signal butterfly valve fault caused by the quality problem of the microswitch itself may occur, but the probability of unqualified products is very low. To judge whether it is the quality problem of the microswitch, the simple method is to use a multimeter to measure and see the change of the resistance value of the microswitch.
測量人員可以先用電表測量微動開關有焊接聯線的一對觸點，記下電阻值，然后用手指壓迫微動開關的觸點簧片后，再測量這一對觸點，如果電阻值發生變化，即可判斷該微動開關功能正常，質量沒有問題。如果有必要，可反復多測幾次來驗證。
The measuring personnel can first measure a pair of contacts of the microswitch with welded wires with an electric meter and record the resistance value, then press the contact reed of the microswitch with a finger, and then measure the pair of contacts. If the resistance value changes, it can be judged that the microswitch functions normally and there is no problem in quality. If necessary, repeat the test several times to verify.
假如能夠驗證出微動開關功能正常后，閥門啟閉信號仍然沒有輸出，可考慮信號蝶閥的啟閉是否到位。無論是手柄移動啟閉閥瓣的信號閥，還是通過渦輪渦桿傳動啟閉閥瓣的信號閥，它們都是通過改變凹凸輪距離，來使微動開關觸點的通斷實現信號輸出的。
If it can be verified that the valve opening and closing signal is still not output after the microswitch function is normal, it can be considered whether the opening and closing of the signal butterfly valve is in place. Whether it is the signal valve for opening and closing the valve flap by moving the handle or the signal valve for opening and closing the valve flap by driving the turbine scroll, the signal output is realized by changing the distance between the concave and convex wheels to make the micro switch contacts on and off.
因此遇到這種現象后，施工調試人員可以在全部關閉或全部開啟信號閥的狀況下，再用萬用表測試。如電阻表仍無變化，可打開信號蝶閥傳動部位的防塵罩蓋，觀察凹凸輪轉動時和微動開關的簧片接觸距離狀況。
Therefore, after encountering this phenomenon, the construction and commissioning personnel can test with a multimeter under the condition that all the signal valves are closed or opened. If the resistance meter still has no change, open the dust cover of the transmission part of the signal butterfly valve and observe the contact distance between the concave cam and the reed of the microswitch when the concave cam rotates.
可能由于因搬動，運輸、安裝作業諸多過程的不當，受外力作用，如碰撞、震動等原因，使微動開關的距離發生移位變化，導致接觸不良。如果確認微動開關的距離移位變化，可調松固定微動開關的兩個小螺絲，把微動開關的距離進行適當調整。使凹凸輪體隨著凹凸面的移動，使微動開關的觸點能隨凹凸面的變化呈現受壓（通）或釋放（斷）的狀態。
Due to improper handling, transportation and installation, the distance of the microswitch may be shifted and changed due to external forces, such as collision and vibration, resulting in poor contact. If the distance displacement of the microswitch is confirmed to change, the two small screws that fix the microswitch can be adjusted to adjust the distance of the microswitch properly. Make the concave convex wheel body move with the concave convex surface, so that the contact of the micro switch can be pressed (on) or released (off) with the change of the concave convex surface.
除了微動開關本身的問題或因微動開關及凹凸輪接觸距離造成的原因。更應該重視信號輸出或顯示系統是否有質量的問題，因為信號輸出顯示系統的故障率一般很高。如這部分出現問題，就應對癥處理，不用再去考慮信號蝶閥的問題了。關注我們

In addition to the problems of the micro switch itself or the contact distance between the micro switch and the concave convex wheel. More attention should be paid to the quality of the signal output or display system, because the fault rate of the signal output and display system is generally high. If there is a problem in this part, deal with the symptom instead of considering the signal butterfly valve. Follow us http://m.xintli.net Yes, learn more!
