    • A novel gas control module switch mechanism includes a diaphragm means, a valve body, a piston means and a fastening means. The diaphragm means has a plurality of diaphragms and a seal plate sandwiched between a first and a second diaphragm. The first diaphragm has a center opening to prevent the first diaphragm from making direct sealing contact. Sealing is done through the seal plate. The seal plate is made of a soft material for obtaining improved sealing effect and longer durability. The valve body has a bulged ring around an opening plane and a bulged body ring for enhancing sealing effect when the seal plate making contact with the bulged ring.
    • 一种新型的气体控制模块开关机构包括隔膜装置,阀体,活塞装置和紧固装置。 隔膜装置具有多个隔膜和夹在第一和第二隔膜之间的密封板。 第一隔膜具有中心开口,以防止第一隔膜直接密封接触。 通过密封板进行密封。 密封板由软质材料制成,用于获得改进的密封效果和更长的耐久性。 阀体具有围绕开口平面的凸出环和凸起的主体环,用于当密封板与凸起环接触时增强密封效果。
