Description
Technical field
The utility model is a kind of anti-deflagration wave gate valve, particularly a kind of anti-deflagration wave gate valve that is installed in shielding engineering feedwater piping origin or beginning.
Background technique
Ripple gate valve poor stability of the prior art only plays buffer function to the shock wave of water, does not have the sense of security truly.
Summary of the invention
The utility model mainly is to solve the deficiencies in the prior art, and a kind of anti-deflagration wave gate valve that Safeguard is installed in valve body is provided.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals:
A kind of anti-deflagration wave gate valve comprises valve body, and two ends of valve body are respectively equipped with water-in flange and water-output flange, be provided with Safeguard in the described valve body, described Safeguard comprises valve seat, is provided with valve opening in the valve seat, and two ends and the valve body of valve seat fix, one side of valve seat is provided with dunnage, be plugged with safety bar on the dunnage, the head of safety bar is provided with valve plate, and the valve opening in valve plate and the valve seat is complementary, be socketed with elastic member on the safety bar, elastic member is located between dunnage and valve plate.In the pressure range of proper functioning, valve plate is supported by spring pressure, can circulate normally, and when the pressure of shock wave entered, valve plate was closed, and before shock wave was blocked in valve plate, the shock wave that has entered into valve body was eliminated by wave damping chamber, played the effect of wave absorption.
As preferably, the rear portion of described valve body is provided with wave damping chamber, and wave damping chamber is connected with valve body.
As preferably, the described elastic member that is socketed on the safety bar is a spring; Be provided with two layers of dunnage in the described valve body, the safety bar two layers of dunnage of pegging graft respectively, spring is arranged between first layer dunnage and valve plate.
As preferably, the water intake of taper is established in the inboard of described water-in flange.
Therefore, the utility model provides a kind of anti-deflagration wave gate valve, and simple in structure, protective is strong, guarantees personal safety.
