Abstract
The invention discloses an impact wave resisting valve. A cut-off valve blade is arranged in a ventilation opening and can move. A rotating shaft is embedded into a valve body. The cut-off valve blade is connected with the rotating shaft through a balance rod. A spring is installed on the balance rod and the cut-off valve blade. During normal ventilation, the cut-off valve blade is located in the middle position of an inner cavity of the valve body under the effect of the rotating shaft, the balance rod and the spring. When positive pressure impact waves are produced and act on the cut-off valve blade, the cut-off valve blade overcomes resistance to move to one side of the valve body so as to be closed with the valve body, and inner and outer channels are cut off. When negative pressure impact waves or negative pressures are generated and act on the cut-off valve blade, the cut-off valve blade overcomes resistance to move to the other side of the valve body so as to be closed with the valve body, and the inner and outer channels are cut off. When the positive pressure and negative pressure acting force disappears, the valve blade recovers to the middle position. According to the impact wave resisting valve, the valve blade can be closed at both the positive pressure effect and the negative pressure effect, and the valve blade can be automatically opened after the positive pressure or negative pressure effect disappears during normal ventilation. The two-way protection effect is achieved, and the advanced function that the single-face spring achieves two-way protection is achieved.
