    • A gate valve comprises a valve body having an internal working fluid passage with a longitudinal axis and an internal gate chamber extending transverse to the working fluid passage. In addition, the gate valve comprises a gate disposed in the internal gate chamber and movable within the gate chamber between a closed position obstructing fluid flow through the working fluid passage and an open position allowing fluid flow through the working fluid passage. Further, the gate valve comprises an internal sealing arrangement coaxially disposed in the working fluid passage and extending between the valve body and the gate to form a barrier between the internal working fluid passage and internal gate chamber. Still further, the gate valve comprises an internal venting passage extending from the internal gate chamber to the internal working fluid passage for selective venting of fluid pressure from the internal gate chamber to the internal working fluid passage.
    • 闸阀包括具有纵向轴线的内部工作流体通道和横向于工作流体通道延伸的内部门室的阀体。 此外,闸阀包括设置在内部门室中的门,并且可在门室内在阻塞流过工作流体通道的流体的关闭位置和允许流体流过工作流体通道的打开位置之间移动。 此外,闸阀包括同轴地设置在工作流体通道中并且在阀体和门之间延伸的内部密封装置,以在内部工作流体通道和内部门室之间形成屏障。 此外,闸阀包括从内部门室延伸到内部工作流体通道的内部通气通道,用于将流体压力从内部门室选择性地排放到内部工作流体通道。
