Problems solved by technology

[0002] The damper is a regulating valve with a relatively simple structure, which is usually used to cut off or throttle the air flow in the pipeline; the existing damper generally includes a valve body, a valve plate, a driving rod, and a sealing ring; the sealing ring is installed on the valve body Inside, the valve plate is sealed or separately connected to the sealing ring inside the valve body, and then the driving rod extends downward from the upper end of the valve body to the upper end of the valve plate inside the valve body, by rotating the driving rod, the driving rod drives the valve plate to rotate, thereby It can complete the opening and closing or separation process around the outer side of the valve plate and the inner wall of the inner sealing ring of the valve body; but the above air valve structure has only one valve plate as the sealing part, and there is no multiple sealing protection structure, so that the sealing effect has hidden dangers

Abstract

The invention discloses a linkage sealing air valve, which comprises a valve body, a driving rod, and a linkage sealing mechanism; Rod, guide column, guide cylinder, connecting rod; the invention realizes the rotary separation of the inner end closure plate or abuts against the inner sealing convex ring through the rotation of the drive rod, and simultaneously realizes the translational separation or abutment of the outer end closure plate Connected to the tapered sealing ring surface, thus realizing the simultaneous double separation or sealing connection effect.
