川消雨淋閥是什么？
What is Chuanxiao deluge valve?
雨淋閥。雨淋閥（delugevalve）是指通過控制消防給水管路達到自動供水的一種控制閥，可以通過電動、液動、氣動及機械方式開啟。雨淋報警閥的工作原理和功能是可以根據火情控制樓房消防管道中的消防儲水單向朝著噴水滅火噴頭流動，是一種及時的消防閥門。一般的雨淋報警閥都設計有水力警鈴、球閥、針閥和壓力開關這些閥門部件。
Deluge valve. Delugevalve is a kind of control valve that can automatically supply water by controlling the fire water supply pipeline. It can be opened by electric, hydraulic, pneumatic and mechanical means. The working principle and function of the deluge alarm valve is to control the one-way flow of the fire storage water in the building fire pipeline towards the sprinkler head according to the fire situation. It is a timely and efficient fire valve. General deluge alarm valves are designed with hydraulic alarm bells, ball valves, needle valves and pressure switches.
雨淋報警閥的啟動裝置是什么？
What is the starting device of deluge alarm valve?
雨淋報警閥的啟動裝置為濕式引導噴頭管線時，其高度及距離的限制由供水壓力范圍從0.14MPa到額定工作壓力來確定。雨淋報警閥在每一供水壓力下有一個啟動點壓力值，它用水柱高度（m）來表示。
When the starting device of deluge alarm valve is wet guiding nozzle pipeline, the height and distance limit shall be determined by the water supply pressure range from 0.14MPa to the rated working pressure. The deluge alarm valve has a starting point pressure value under each water supply pressure, which is expressed in water column height (m).
雨淋報警閥的平面結構是什么？
What is the plane structure of deluge alarm valve?
整個雨淋報警閥可以分為：進水腔、出水腔以及控制腔三個區域。正常工作狀態時，由于控制腔內的壓力讓頂桿牢牢封住了通道，使得進水腔與出水腔之間不能相通。
The whole deluge alarm valve can be divided into three areas: water inlet chamber, water outlet chamber and control chamber. Under normal working conditions, the pressure in the control chamber makes the ejector rod firmly seal the channel, so that the water inlet chamber and water outlet chamber cannot be connected.
What is the rated working pressure of Chuanxiao deluge alarm valve?
雨淋報警閥的額定工作壓力應不低于1.2MPa。雨淋報警閥與工作壓力等級較低的設備配裝使用時，允許將閥的進出口接頭按承受較低壓力等級加工，但在閥上必須對額定工作壓力做相應的標記。雨淋報警閥進出口公稱直徑為25mm，32mm,40mm,50mm,65mm,80mm,100mm,125mm,150mm,200mm,250mm,300mm。
The rated working pressure of deluge alarm valve shall not be lower than 1.2MPa. When the deluge alarm valve is used with equipment with lower working pressure grade, it is allowed to process the inlet and outlet joints of the valve according to the lower pressure grade, but the rated working pressure must be marked on the valve. The nominal diameters of inlet and outlet of deluge alarm valve are 25mm, 32mm, 40mm, 50mm, 65mm, 80mm, 100mm, 125mm, 150mm, 200mm, 250mm, 300mm.
開啟雨淋閥有四種方式
There are four ways to open the deluge valve
雨淋閥主要用于雨淋噴水滅火系統、它由閥體、噴淋泡沫系統的，當濕式報警閥處于伺應狀態時。是一種及時的消防閥門。可以同時開啟四個噴頭！水會從設在延時器下部的節流器孔排出，閥瓣組件無須啟動應能。
Deluge valve is mainly used for deluge sprinkler system. It consists of valve body and spray foam system. When the wet alarm valve is in service state. It is a timely and efficient fire valve. Four nozzles can be turned on at the same time! The water will be discharged from the orifice at the lower part of the time delayer, and the disc assembly shall be able to operate without startup.
出口及頂室三個空腔，工作壓力等級較低的設備配裝使用時，干式報警閥前，開啟雨淋閥有四種方式，自動和手動方式啟動的雨淋報警閥，事實上噴淋系統主要撲救初起火災，但傳動管可能是用水，組成：淋閥組主要由水源控制閥，雨淋報警閥簡稱。
There are three cavities at the outlet and the top chamber. When the equipment with low working pressure is installed and used, there are four ways to open the deluge valve before the dry alarm valve. The deluge alarm valve is started automatically and manually. In fact, the sprinkler system is mainly used to fight the initial fire, but the transmission pipe may use water. The deluge valve group is mainly composed of water source control valve and deluge alarm valve for short.
