细水雾灭火系统分区控制阀设置要求
来源：http://www.cx-fire.com/ 日期：2023-05-20
分区控制阀是能接收控制信号并自动开启，使细水雾喷头向对应的防护对象喷放实施灭火的控制阀。细水雾灭火系统分区控制阀分为开式、闭式两种。开式系统的分区控制阀平时保持关闭，火灾时能够接收控制信号自动开启，使细水雾向对应的防护区.或保护对象喷放。闭式系统的分区控制阀平时保持开启，主要用于切断管网的供水水源，以便系统排空、检修管网及更换喷头等。下面
川消小编来讲讲其中的设置要求：
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. 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. Below, the editor of Chuanxiao will explain the setting requirements:
1、开式系统应按防护区设置分区控制阀。每个分区控制阀上或阀后邻近位置，宜设置泄放试验阀。
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、闭式系统应按楼层或防火分区设置分区控制阀。分区控制阀应为带开关锁定或开关指示的阀组。
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、分区控制阀宜靠近防护区设置，并应设置在防护区外便于操作、检查和维护的位置。
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.
分区控制阀上宜设置系统动作信号反馈装置。当分区控制阀上无系统动作信号反馈装置时，应在分区控制阀后的配水干管上设置系统动作信号反馈装置。
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、闭式系统的高点处宜设置手动排气阀，每个分区控制阀后的管网应设置试水阀，并应符合下列规定：
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:
试水阀前应设置压力表；
A pressure gauge should be installed in front of the water testing valve;
试水阀出口的流量系数应与一只喷头的流量系数等效；
The flow coefficient at the outlet of the water testing valve should be equivalent to the flow coefficient of one nozzle;
试水阀的接口大小应与管网末端的管道一致，测试水的排放不应对人员和设备等造成危害。
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.
5、分区控制阀的安装高度宜为1.2m～1.6m，操作面与墙或其他设备的距离不应小于0.8m，并应满足操作要求。
5. 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 requirements for setting the partition control valve of the fine water mist fire extinguishing system. We hope it can help you. If you have any doubts or needs, feel free to consult us at any time http://www.cx-fire.com ！
