    • A dump valve for a high pressure fluid line includes a base, a fitting secured to the base and adapted to be interposed along the high pressure fluid line. The fitting defined an internal manifold having a dump port in communication with the manifold. A hydraulic or pneumatic cylinder is mounted on the base at a position for forcing a valve member into a valve closed position in engagement with a valve seat within the dump port. The fluid cylinder exerts a continuous force to maintain the valve member in the valve closed position against the urging of fluid pressure within the manifold. In an emergency condition, the fluid cylinder allows the valve member to withdraw from the valve seat, thereby ejecting pressurized fluid from the dump port.
    • 用于高压流体管线的排放阀包括底座,固定到基座上并适于沿着高压流体管路插入的配件。 配件限定了具有与歧管连通的倾卸端口的内部歧管。 液压或气动缸安装在基座上的位置,用于迫使阀构件进入阀关闭位置,与转储端口内的阀座接合。 流体缸施加连续的力以将阀构件保持在阀关闭位置,以抵抗歧管内的流体压力的推动。 在紧急情况下,流体缸允许阀构件从阀座排出,从而从加压口排出加压流体。
