Before the boost, tighten the holding bolt, the floating valve cover rises, so that between the valve cover and the elastic wedge pad, elastic wedge pad and valve body between the spin tight sealing force. When the dielectric pressure action, the valve cover is moved upward by the dielectric pressure, the containment bolts begin to unload, the valve cover and wedge-shaped gasket, as well as the valve body and wedge-shaped gasket between the sealing ratio pressure, with the increase of pressure and gradually increase, to ensure a good seal, dense cover on the work seal ratio pressure by two parts synthesis Second, the specific pressure formed by the dielectric pressure, the higher the dielectric pressure, the larger the working seal than the pressure, the better the sealing performance.
