川消干式报警阀定义自动喷水灭火系统中的一种控制阀门。它是在其出口侧充以压缩气体，当气压低于某一定值时能使水自动流入喷水系统并进行报警的单向阀。下面认识下该设备吧。

Dry alarm valve defines a control valve in automatic sprinkler system. It is a one-way valve filled with compressed gas at its outlet. When the air pressure is lower than a certain value, it can make water automatically flow into the sprinkler system and give an alarm. Now let's meet the equipment.

干式报警阀的额定工作压力应不低于1.2MPa。干式报警阀与工作压力等级较低的设备配装使用时，允许将阀的进出口接头按承受较低压力等级加工，但在阀上须对额定工作压力做相应的标记.

The rated working pressure of dry alarm valve shall not be less than 1.2MPa. When the dry-type alarm valve is used with equipment with lower working pressure level, it is allowed to process the inlet and outlet joints of the valve according to the lower pressure level, but the rated working pressure must be marked on the valve

阀在关闭位置，阀瓣组件与阀座内缘之间少有3mm的半径间隙。阀座的环形空间深度不应小于3mm,轴与轴套之间的径向间隙不应小于0.125mm。阀瓣轴销与阀体支承端面之间的轴向间隙不应小于0.25mm。

When the valve is in the closed position, there is at least a 3mm radius gap between the disc assembly and the inner edge of the valve seat. The depth of the annular space of the valve seat shall not be less than 3mm, and the radial clearance between the shaft and the shaft sleeve shall not be less than 0.125mm. The axial clearance between the disc shaft pin and the supporting end face of the valve body shall not be less than 0.25mm.

阀体中对阀的开启起主导作用的任何往复运动的导向零件，在活动件进入固定处的小径向间隙不应小于0.7mm,阀处于伺应状态时，活动件与固定件的小径向间隙不应小于0.125mm。耐腐蚀的阀瓣导套、轴销、轴承与其他黑色金属零件之间的间距不应小于3mm。

For any reciprocating guide part in the valve body that plays a leading role in the opening of the valve, the radial clearance between the movable part and the fixed part shall not be less than 0.7mm when the movable part enters the fixed part. When the valve is in the waiting state, the radial clearance between the movable part and the fixed part shall not be less than 0.125mm. The distance between the corrosion-resistant disc guide sleeve, shaft pin, bearing and other ferrous metal parts shall not be less than 3mm.

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、干式报警阀应设置在无冰冻危险的环境中，要求安装场所采光充足，采暖良好，有足够的安装空间。

2. The dry-type alarm valve should be set in an environment without freezing danger. The installation site is required to have sufficient lighting, good heating and enough installation space.

3、干式报警阀宜设置在及易于操作的地点，阀座法兰距地面高度宜为1.2m左右。

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

4、将干式报警阀安装于管网系统之前，应清洗供水管网，保证供水管网干净、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、阀盖密封垫，检查阀瓣动作是否灵活。确认动作灵活后，装好阀盖密封垫和阀盖。

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

6、将干式报警阀安装在系统中，下端与供水管道相连，上端与系统喷淋管网相连。

6. Install the dry alarm valve in the system, with the lower end connected to the water supply pipeline and the upper end connected to the system spray pipe network.

注意：干式报警阀须直立安装。建议干式报警阀两侧距墙不小于0.5m，正面距墙不小于1.5m，所有排水口均采取排水措施。更多注意事项额蓼的了解您可以随时来网站http://www.cx-fire.com咨询。

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 is not less than 0.5m, and the distance from the front side to the wall is not less than 1.5m. Drainage measures should be taken for all drains. For more information, you can come to the website at any time http://www.cx-fire.com consulting service
