雨淋報警閥和濕式報警閥的主要區(qū)別
來源：http://www.xintli.net/ 日期：2022-05-09
雨淋報警閥的工作原理是通過水和系統(tǒng)的壓力作用到主控制閥使閥門打開或關(guān)閉，達到滅火的功能。雨淋報警閥是在發(fā)生火災(zāi)時閥門才打開，平時管道內(nèi)沒有水，可以防止生銹或者凍裂。一旦發(fā)生情況可以快速進行供水，在消防管道系統(tǒng)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(tǒng)保護區(qū)內(nèi)就近的感煙、感溫探測器組成與門，當二者均動作后，通控制電路開啟雨淋報警閥，并返回動作信號。
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(tǒng)保護的防火分區(qū)內(nèi)任意火災(zāi)探測器報警，確認火災(zāi)后，由火災(zāi)自動報警控制器發(fā)出控制信號輸人輸出模塊，開啟雨淋報警閥，并返回動作信號，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.
濕式報警閥壓力開關(guān)的接點和消防控制室手動按鈕應(yīng)直接延時起泵，在無消防控制室的工程中，應(yīng)把濕式報警閥壓力開關(guān)的接點線路直接引濕式噴水滅火系統(tǒng)噴淋泵的控制箱內(nèi)。
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.
實現(xiàn)直接延時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(nèi)應(yīng)設(shè)手動聯(lián)動控制臺，將壓力開關(guān)的接點線路引控制臺，經(jīng)轉(zhuǎn)換后實現(xiàn)自動和手動直接控制噴淋泵，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(qū)別就是系統(tǒng)處于準工作狀態(tài)時的情況，閉式的報警閥是常開的，噴頭噴水后不需要再打開報警閥。
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(zāi)自動報警系統(tǒng)聯(lián)動，火警信號確認后，打開雨淋報警閥，然后用穩(wěn)壓裝置提供壓力，然后將電磁閥打開后，壓力開關(guān)動作，啟動消防水泵，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.
