Alarm Check Valve Price Philippines

The wet alarm valve is mainly composed of a valve body, a valve seat, a valve disc, a sealing gasket, a connecting rod, an annular groove bypass connecting pipe, and a pressure gauge connection pipe.

The wet alarm valve should be installed on the main standpipe of the sprinkler system, and the installation height should be in accordance with the design and standard network collection requirements, and the drain pipe should not be connected to the drainage system only. The drain funnel should be connected to the nearby drain point.

The matters needing attention during installation and operation of the wet alarm valve are as follows.

1. When installing the wet alarm valve, pay attention to the direction of the valve body. And carry out pipeline flushing before installation to avoid sedimentation of mud, sand and dirt, and to prevent blockage of the annular groove.

2. During installation, if it is found that even if the wet alarm valve is closed, there is still water flowing out of the drain port of the delayer, indicating that the valve flap is not tightly sealed and should be checked, repaired or updated.

3. The working status of the alarm system should be checked regularly. Generally, water can be discharged through the end test device of the automatic sprinkler system to confirm whether the pressure switch, hydraulic alarm bell and wet alarm valve are normally watered.

4. Frequently check whether the pipeline system is blocked. The inspection method is: close the valve on the pipeline to the delayer and hydraulic alarm bell, and open the ball valve of the main drain pipe. If a large amount of water flows out, the pipeline is unobstructed.
