Description

Technical Field

[0001] The utility model relates to the technical field of wet alarm valves, in particular to a fire-fighting wet alarm valve with an anti-leakage function. Background Art

[0002] A wet alarm valve is a one-way valve that only allows water to flow into the sprinkler system in one direction and alarms at a specified flow rate. The wet alarm valve usually has equal water pressure before and after the valve disc (water passes through the water pressure balance hole in the guide pipe to maintain the water pressure balance before and after the valve disc). It also plays a certain role in the field of fire protection. The main function of the fire protection wet alarm valve is to prevent the spread of fire. When a fire occurs, the alarm valve will detect the change in water pressure in time and send out an alarm signal. At the same time, it will automatically start the fire extinguishing system and spray fire extinguishing agent to the fire source, thereby extinguishing the fire and preventing the fire from spreading. The fire protection wet alarm valve can also automatically alarm. The wet alarm valve is usually installed and sealed with a flange, so that the wet alarm valve can be leak-proof and installed.

[0003] When installing a wet alarm valve through a flange, multiple sets of bolts are usually used for installation. This installation method requires manual installation of the bolts using tools, which takes a long time and is cumbersome. At the same time, during the installation of the bolts, a large amount of force is required to make the two pipes fit tightly together, which can easily lead to exhaustion of the installer in the long run. At the same time, when disassembling the flange, the bolts need to be removed one by one, which wastes time, is not conducive to the rapid disassembly of the flange, is not conducive to the rapid installation and disassembly of the wet alarm valve, and is not conducive to the use of the wet alarm valve.
