PADDLE TYPE ALARM VALVE ASSEMBLY USING A BUTTERFLY VALVE CAPABLE OF REDUCING WATER LEAK

摘要

PURPOSE: A paddle type alarm valve assembly using a butterfly valve is provided to inspect the operation of a flow sensing alarm of the alarm valve assembly without operating a sprinkler.;CONSTITUTION: A paddle type alarm valve assembly using a butterfly valve comprises a housing(100), a check valve(20), a butterfly valve(200), a flow sensing alarm(30), a drain valve(400), a first pressure gauge, and a second pressure gauge. The check valve is installed between one end(110) and the other end(120) of a flow path(102) and allows fluid to flow from one end to the other end of the flow path. The butterfly valve opens or closes a gap between one end of the flow path and the check valve. The flow sensing alarm closes the inlet(130) of the housing and has a paddle(32) rotated depending on the flow of the fluid.;COPYRIGHT KIPO 2011
