Abstract
The utility model provides a Wet-type alarm valve for fire fighting, which is composed of a valve body (1), a valve plate (2), a sealing gasket (3) and a valve seat (4). The main technical feature of the utility model is that the sealing gasket (3) is fixed on the valve seat (4), and thus the disadvantage that sealing property is difficult to guarantee because of the misplacement of the sealing gasket in the prior art is further overcome. The utility model has the advantages of good sealing property, easy machining, etc. The utility model can be widely used in various automatic sprinkling fire extinguishing systems.
Description
The utility model relates to a kind of valve, the fire-fighting wet alarm valve that particularly a kind of automatic sprinkler system is used.
At present, the fire-fighting wet alarm valve of widespread usage is a kind of valve plate formula check valve structure both at home and abroad, and elastic sealing gasket is installed on the valve plate, is distributed with several apertures on the valve seat, and straight-through valve is external, and valve plate can rotation outside the valve seat periphery.The shortcoming of this structure is that the dislocation because of sealing gasket makes sealing be difficult to guarantee.
The purpose of this utility model, the above-mentioned shortcoming that exists at prior art and a kind of fire-fighting wet alarm valve of designing exactly.Be characterized in sealing gasket has been installed on valve seat, and then overcome prior art and misplace the shortcoming that the sealing that causes is difficult to guarantee because of sealing gasket.
The utility model is made up of valve body, valve seat, valve plate, sealing gasket.Valve seat snugly fits in the valve body, and sealing gasket is fixed on the valve seat, and valve plate is installed in simultaneously can rotation outside the valve seat periphery on the valve body.It is external to be distributed with the straight-through valve of several apertures on valve seat and the sealing gasket, can adopt bonding between sealing gasket and the valve seat or alternate manner connects.
Accompanying drawing is a structural principle schematic diagram of the present utility model.
(1) in the accompanying drawing is valve body; (2) be valve plate; (3) be sealing gasket; (4) be valve seat
When using fire-fighting wet alarm valve shown in the drawings, this valve is installed in whole automatic sprinkler system is responsible for.Under normal circumstances (promptly there is not the fire alarm situation), system's stable water pressure, valve plate (2) fits tightly on sealing gasket (3), and water can not be flow to outside the valve body (1) along the water hole on valve seat (4) and the sealing gasket (3).When having under the fire alarm situation, system acting makes hydraulic pressure produce fluctuation, valve plate (2) spin-up, make water along the orifice flow on valve seat (4) and the sealing gasket (3) outside valve body (1).When having under the fire alarm situation, system acting makes hydraulic pressure produce fluctuation, valve plate (2) spin-up, make water along the orifice flow on valve seat (4) and the sealing gasket (3) outside valve body (1) and play the warning effect.
The utlity model has good airproof performance, be easy to the advantages such as processing. Can be widely used in Various automatic sprinkler systems.
Claims (2)
1, the fire-fighting wet alarm valve is by valve body (1), valve plate (2), and sealing gasket (3), valve seat (4) is formed, and it is characterized in that being fixed with on the valve seat (4) sealing gasket (3).
2, the fire-fighting wet alarm valve described in the claim 1 is characterized in that between valve seat (4) and the sealing gasket (3), can adopt bonding or the alternate manner connection.
