1、干式报警阀应在系统管网试压、冲洗合格后进行。

1. The dry-type alarm valve shall be carried out after the pressure test and flushing of the system pipe network are qualified.

2、干式报警阀应安装在无冰冻危险的环境中，要求安装场所采光充足、采暖好、安装空间充足。

2. The dry-type alarm valve should be installed in an environment without freezing danger. It is required that the installation site has sufficient lighting, heating and installation space.

3、干式报警阀应设置在、便于操作的位置，阀座法兰距地面的高度应在1.2m左右。

3. The dry alarm valve should be set in a safe and easy to operate position, and the height of the valve seat flange from the ground should be about 1.2m.

4、管网系统安装干式报警阀前，应对供水管网进行清洗，确保供水管网清洁无异物。

4. Before installing the dry alarm valve in the pipe network system, the water supply pipe network should be cleaned to ensure that the water supply pipe network is clean and free of foreign matters.

5、拆下阀盖和阀盖垫片，检查阀瓣是否灵活。确认动作灵活后，安装阀盖垫片和阀盖。

5. Remove the bonnet and bonnet gasket and check whether the disc is flexible. After confirming that the action is flexible, install the bonnet gasket and bonnet.

6、系统内安装干式报警阀，下端接供水管路，上端接系统喷淋管网。注意：干式报警阀必须直立安装。建议干式报警阀两侧距离墙面不小于0.5m，正面到墙面距离不小于1.5m。

6. A dry alarm valve is installed in the system, with the lower end connected to the water supply pipeline and the upper end connected to the system spray pipe network. Note: the dry alarm valve must be installed vertically. It is recommended that the distance from both sides of the dry alarm valve to the wall should not be less than 0.5m, and the distance from the front to the wall should not be less than 1.5m.

川消小编提醒，通常，报警阀后面的管网充满压力气体，从水源到报警阀前端的管段充满压力水。干式自动喷水灭火系统发生火灾时，火源处温度升高，使火源上方的喷水器打开，管网内的压缩空气排出，因此管网压力经过报警阀下降，干式报警阀阀前压力大于阀后压力，干式报警阀打开，水流配水管网，通过打开的洒水器洒水灭火。

Chuanxiao Xiaobian reminded that usually, the pipe network behind the alarm valve is full of pressure gas, and the pipe section from the water source to the front end of the alarm valve is full of pressure water. When a fire occurs in the dry-type automatic sprinkler system, the temperature at the fire source rises, so that the sprinkler above the fire source is opened, and the compressed air in the pipe network is discharged. Therefore, the pipe network pressure drops through the alarm valve. The pressure in front of the dry-type alarm valve is greater than the pressure behind the valve. The dry-type alarm valve is opened, and the water flows to the water distribution pipe network, and the water is sprinkled through the open sprinkler.

在干式系统中，报警阀上下阀板的压力保持平衡。当系统管网有轻微漏气时，使用空压机补充空气。安装在供气管道上的压力开关监测系统管网的气压变化。

In the dry system, the pressure of the upper and lower valve plates of the alarm valve remains balanced. When there is slight air leakage in the system pipe network, use the air compressor to make up air. The pressure switch installed on the gas supply pipeline monitors the pressure change of the system pipe network.
