Description

Technical Field

[0001] This utility model relates to the field of valve technology, and in particular to an anti-clogging wet alarm valve. Background Technology

[0002] A wet alarm valve is a type of valve that ensures that the valve can act quickly and accurately and output an alarm signal when a fire occurs. Traditional wet alarm valves are prone to filter clogging due to impurities in the water, resulting in poor water flow, delayed alarm, or even failure, which increases fire risk. In addition, manual cleaning is frequent and maintenance costs are high.

[0003] A wet alarm valve disclosed in CN202128844U includes a valve body, valve seat, valve disc assembly, compensating check valve, water supply pressure gauge, system-side pressure gauge, test valve, drain valve, delay device, pressure switch, and hydraulic alarm bell. It also includes an automatic pressure and flow regulator installed on a flow compensation pipeline. The advantage of this invention compared to existing technologies is that the automatic pressure and flow regulator eliminates the height restriction on the network pipe side of the wet alarm and fire extinguishing system.

[0004] However, this wet alarm valve has the following disadvantages: it is not effective at filtering impurities, is prone to clogging, and will reduce the efficiency of the equipment. Utility Model Content

The buffer assembly includes a fixed shaft fixedly connected to one side of the sealing gasket, and a connecting rod rotatably connected to one side of the fixed shaft. The connecting rod, when the sealing gasket is opened, rotates with the sealing gasket and compresses the telescopic spring.

[0009] As a further embodiment of this utility model, a protective shell is fixedly connected to one side of the filter box, and a motor is fixedly connected to one side of the protective shell. The motor drives the pulley to rotate.

[0010] As a further embodiment of this utility model, a pulley is fixedly connected to one side of the motor, a belt is slidably connected to one side of the pulley, and a pulley is slidably connected to one side of the belt. The pulley is used to drive the rotating rod to rotate.

[0011] As a further embodiment of this utility model, a coarse filter screen is fixedly connected to one side of the filter box, and a sealing ring is fixedly connected to one side of the rotating rod. The sealing ring serves to seal the filter box.

[0012] As a further embodiment of this utility model, a collection shell is slidably connected to the bottom of the filter box, a telescopic spring is fixedly connected to one side of the first connecting rod, and a second connecting rod is fixedly connected to one side of the telescopic spring. The second connecting rod is used to compress the rubber block.

[0015] (III) Beneficial Effects

[0016] This utility model provides an anti-clogging wet alarm valve, which has the following beneficial effects:

[0017] 1. This anti-clogging wet alarm valve, through the setting of the filter assembly, when in use, the motor is started, causing pulley one to rotate. The rotation of pulley one causes pulley one and the belt to rotate pulley two. The two pulleys drive two rotating rods to rotate, which in turn drive two brushes to rotate. This achieves the function of the brushes cleaning the coarse and fine filter screens, reducing clogging accidents, improving equipment working efficiency, and enhancing the filtration effect through two-stage filtration.

[0018] 2. This anti-clogging wet alarm valve, through the setting of the buffer component, opens through the sealing gasket during use, causing the sealing gasket to drive the fixed shaft one and the connecting rod one to rotate upward. The upward rotation of the connecting rod one compresses the telescopic spring, which in turn causes the connecting rod two to rotate upward under the pressure. The pressure on the connecting rod two causes the fixed shaft two to squeeze the rubber block, thereby achieving a buffering effect, reducing the interference of vibration during operation, extending the service life of the sealing gasket, and reducing the probability of false alarms.
