雨淋報警閥和濕式報警閥的主要區別

雨淋報警閥的工作原理是通過(guò)水和系統的壓力作用到主控制閥使閥門(mén)打開(kāi)或關(guān)閉，達到滅火的功能。雨淋報警閥是在發(fā)生火災時(shí)閥門(mén)才打開(kāi)，平時(shí)管道內沒(méi)有水，可以防止生銹或者凍裂。一旦發(fā)生情況可以快速進(jìn)行供水，在消防管道系統中使用效果非常好。
The working principle of the rain alarm valve is to open or close the main control valve through water and system pressure, so as to achieve the function of extinguishing the fire. Rain alarm valve is only opened in case of fire, usually there is no water in the pipeline, can prevent rust or freeze crack. In case of emergency, water supply can be carried out quickly, which is very good for use in fire protection piping system.
雨淋報警閥由滅火系統保護區內就近的感煙、感溫探測器組成與門(mén)，當二者均動(dòng)作后，通控制電路開(kāi)啟雨淋報警閥，并返回動(dòng)作信號。
The rain alarm valve is composed of the nearest smoke detector and temperature detector in the fire extinguishing system protection area. When both of them operate, the control circuit will open the rain alarm valve and return the action signal.
由噴水滅火系統保護的防火分區內任意火災探測器報警，確認火災后，由火災自動(dòng)報警控制器發(fā)出控制信號輸人輸出模塊，開(kāi)啟雨淋報警閥，并返回動(dòng)作信號，從報警可靠性考慮宜采用第二種控制方式。
Any fire detector in the fire protection zone protected by sprinkler system alarms, and after confirming the fire, the automatic fire alarm controller sends control signal to the input and output module, opens the rain alarm valve, and returns the action signal. Considering the reliability of alarm, the second control mode should be adopted.
濕式報警閥壓力開(kāi)關(guān)的接點(diǎn)和消防控制室手動(dòng)按鈕應直接延時(shí)起泵，在無(wú)消防控制室的工程中，應把濕式報警閥壓力開(kāi)關(guān)的接點(diǎn)線(xiàn)路直接引濕式噴水滅火系統噴淋泵的控制箱內。
The contact of the pressure switch of the wet alarm valve and the manual button of the fire control room should delay the pump directly. In the project without the fire control room, the contact line of the pressure switch of the wet alarm valve should be directly led to the control box of the spray pump of the wet sprinkler system.
實(shí)現直接延時(shí)起泵和顯示信號的功能，在有消防控制室的工程中，消防控制室內應設手動(dòng)聯(lián)動(dòng)控制臺，將壓力開(kāi)關(guān)的接點(diǎn)線(xiàn)路引控制臺，經(jīng)轉換后實(shí)現自動(dòng)和手動(dòng)直接控制噴淋泵，并顯示信號。
In the project with fire control room, manual linkage console should be set in the fire control room to lead the contact line of the pressure switch to the console. After conversion, automatic and manual direct control of the spray pump is realized, and the signal is displayed.
川消雨淋報警閥和濕式報警閥的主要區別就是系統處于準工作狀態(tài)時(shí)的情況，閉式的報警閥是常開(kāi)的，噴頭噴水后不需要再打開(kāi)報警閥。
The main difference between the water sprinkler alarm valve and the wet alarm valve is the situation when the system is in the quasi-working state. The closed alarm valve is normally open, and the alarm valve does not need to be opened after the sprinkler sprays.
而雨淋報警閥是常閉的，需要與火災自動(dòng)報警系統聯(lián)動(dòng)，火警信號確認后，打開(kāi)雨淋報警閥，然后用穩壓裝置提供壓力，然后將電磁閥打開(kāi)后，壓力開(kāi)關(guān)動(dòng)作，啟動(dòng)消防水泵，噴頭噴水滅火。
The drench alarm valve is normally closed, and it needs to be linked with the automatic fire alarm system. After the fire alarm signal is confirmed, the drench alarm valve is opened, and then the pressure regulator is used to provide pressure. After the solenoid valve is opened, the pressure switch acts to start the fire pump and spray water to extinguish the fire.
