ZSFZ type wet alarm valve

Abstract

The invention provides a ZSFZ type wet alarm valve, relates to the technical field of alarm valves, and solves the problems that when an existing wet alarm valve is used, impurities in a pipeline cannot be cleaned, so that the pipeline is easy to block, the alarm function is influenced, the existing wet alarm valve does not have an inspection function, and whether a product runs normally or not is difficult to detect. One end of the water supply pipeline is connected with a butterfly valve, the top end of the butterfly valve is connected with an alarm valve, the top end of the alarm valve is connected with a flange, one side of the alarm valve is connected with a first ball valve, one side of the first ball valve is connected with a second ball valve, one side of the second ball valve is connected with a filter, and one side of the filter is connected with a first three-way pipe. One end of the first three-way pipe is connected with a delayer, the top end of the delayer is connected with a second three-way pipe, and one end of the second three-way pipe is connected with a hydraulic alarm bell. Impurities in the pipeline can be effectively cleaned, pipeline blockage is avoided, the inspection function is achieved, and the practical value is high.

Description

technical field [0001] The invention belongs to the technical field of alarm valves, and more particularly, particularly relates to a ZSFZ type wet alarm valve. Background technique [0002] The wet alarm valve is a one-way valve that only allows water to flow into the sprinkler system in one direction, and drives the supporting parts to alarm under the specified pressure and flow. The wet automatic sprinkler fire extinguishing system composed of water flow indicator, pressure switch, sprinkler head, etc. is a fixed fire extinguishing system that is widely used. The pipe network of the system is filled with clean water under a certain pressure all the year round, and it is in a standby working state for a long time. When a fire occurs somewhere in the protection area, the ambient temperature in the area rises, and the organic solution in the heat sensitive element (glass ball) of the sprinkler head The thermal expansion generates a large internal pressure until the glass ba...
