細水霧滅火系統分區控制閥的設置要求

分區控制閥是能接收控制信號并自動開啟，使細水霧噴頭向對應的防護對象噴放實施滅火的控制閥。細水霧滅火系統分區控制閥分為開式、閉式兩種。
The zone control valve is a control valve that can receive control signals and automatically open, causing the fine water mist nozzle to spray towards the corresponding protective object to implement fire extinguishing. The partition control valves of the fine water mist fire extinguishing system are divided into two types: open and closed.
開式系統的分區控制閥平時保持關閉，火災時能夠接收控制信號自動開啟，使細水霧向對應的防護區.或保護對象噴放。閉式系統的分區控制閥平時保持開啟，主要用于切斷管網的供水水源，以便系統排空、檢修管網及更換噴頭等。
The partition control valve of the open system is usually kept closed, and can receive control signals to automatically open in case of a fire, causing fine water mist to spray towards the corresponding protective zone or object. The partition control valve of the closed system is usually kept open, mainly used to cut off the water supply source of the pipeline network, so as to facilitate system emptying, maintenance of the pipeline network, and replacement of nozzles.

川消小編來講講細水霧滅火系統分區控制閥設置要求：
Below, the editor of Sichuan Xiaoxiao will explain the requirements for setting the partition control valves of the fine water mist fire extinguishing system:
1、開式系統應按防護區設置分區控制閥。每個分區控制閥上或閥后鄰近位置，宜設置泄放試驗閥。
1. The open system should be equipped with partition control valves according to the protection zone. A discharge test valve should be installed on or adjacent to the control valve in each zone.
2、閉式系統應按樓層或防火分區設置分區控制閥。分區控制閥應為帶開關鎖定或開關指示的閥組。
2. Closed systems should be equipped with partition control valves based on floors or fire compartments. The zone control valve should be a valve group with switch locking or switch indication.
3、分區控制閥宜靠近防護區設置，并應設置在防護區外便于操作、檢查和維護的位置。
3. The partition control valve should be set up close to the protective zone and should be located outside the protective zone for easy operation, inspection, and maintenance.
分區控制閥上宜設置系統動作信號反饋裝置。當分區控制閥上無系統動作信號反饋裝置時，應在分區控制閥后的配水干管上設置系統動作信號反饋裝置。
A system action signal feedback device should be installed on the partition control valve. When there is no system action signal feedback device on the partition control valve, a system action signal feedback device should be installed on the water distribution main pipe behind the partition control valve.
4、閉式系統的高點處宜設置手動排氣閥，每個分區控制閥后的管網應設置試水閥，并應符合下列規定：
4. Manual exhaust valves should be installed at the high points of the closed system, and water testing valves should be installed in the pipeline network after each zone control valve, which should comply with the following regulations:
試水閥前應設置壓力表；
A pressure gauge should be installed in front of the water testing valve;
試水閥出口的流量系數應與一只噴頭的流量系數等效；
The flow coefficient at the outlet of the water testing valve should be equivalent to the flow coefficient of one nozzle;
試水閥的接口大小應與管網末端的管道一致，測試水的排放不應對人員和設備等造成危害。
The interface size of the water testing valve should be consistent with the pipeline at the end of the pipeline network, and the discharge of testing water should not cause harm to personnel and equipment.
分區控制閥的安裝高度宜為1.2m～1.6m，操作面與墻或其他設備的距離不應小于0.8m，并應滿足操作要求。
The installation height of the partition control valve should be 1.2m-1.6m, and the distance between the operating surface and the wall or other equipment should not be less than 0.8m, and it should meet the safety operation requirements.
That's all for the setting requirements of the partition control valve for the fine water mist fire extinguishing system. We hope it can be helpful to you. For more information, please come to our website http://m.xintli.net Consult!
