    • A valve assembly has an outer body with an internal passageway for gas containing a valve seat and a valve member which can be lifted from the valve seat by rearward pressure. An inner body is threaded in the passageway, and itself includes an internal passage and a plunger within the passage. The plunger has a forward hollow sleeve portion and two arms extending rearwardly at diametrally opposite positions, the arms being linked at their rearward ends by a bridge from which extends an activating member adapted to hold the valve member away from the valve seat. The plunger has a sealing member forwardly of the activating member for closing the internal passage when the plunger is in a forward position. The inner body has two opposed grooves to receiving the arms, thus interlocking the plunger and the inner body so that rotation of the one requires rotation of the other. The bridge portion can be engaged by a forked tool for rotating it.
    • 阀组件具有外部主体,其具有用于气体的内部通道,所述内部通道包含阀座和阀构件,该阀构件可以通过向后的压力从阀座提升。 内部主体在通道中螺纹连接,并且其本身在通道内部包括内部通道和柱塞。 柱塞具有前空心套筒部分和两个沿直径相对的位置向后延伸的臂,臂在其后端处通过桥连接,桥接器延伸有适于将阀构件保持远离阀座的致动构件。 柱塞在活塞构件的前方具有密封构件,用于当柱塞处于向前位置时关闭内部通道。 内体具有两个相对的凹槽以接收臂,从而使柱塞和内体互锁,使得旋转需要另一个旋转。 桥接部分可以被叉形工具接合以使其旋转。
