When the medium flows in the specified direction,the valve disc is pushed open by the force of the medium to realize the opening;
When the medium flows in the specified direction,the valve disc is pushed open by the force of the medium to realize the opening;
When the medium countercurrent,due to the spring force on the back of the valve disc and the effect of the medium reverse force,the valve disc and the sealing surface of the seat are closely fitted and closed,because the sealing surface of the valve disc is sealed by rubber,so as to achieve the purpose of noise reduction and prevent the medium countercurrent.
