【文章內(nèi)容簡(jiǎn)介】 t lever to resist, pressed air through the shaft sleeve cavity is slow. Main principle is one of the main air flow set up above a punching device (soft gasket) blocked air flow, similar to ram anti reflux device, push in the process of air door closed cavity pressed air to shim block air flow, and a small inlet hole slowly to get out from the other. Through this way can avoid because of the negative pressure effect of air quickly shut down, forming a slowly closed. Structure diagram as shown in figure: 2, throttle pneumatic pressurerelief devices function: through the throttle slowly closing process, to avoid impact damper, rapidly because of the large negative pressure caused by air door deformation, crack, air door wall, wall crack, slag, affecting the service life of air door, affect the quality and appearance. Using the throttle pressure relief device can effectively avoid air inlet negative pressure big crowded in
