    摘要: A valve apparatus that has a longitudinal axis therethrough comprises a valve seat member, a valve closure member, a fluid flow path, and a screening member. The valve seat member comprises a hollow bore and a first frustoconical contact surface. The valve closure member comprises a body and a second frustoconical contact surface that is adapted to seal against the first frustoconical contact surface. The valve closure member is movable along the longitudinal axis of the valve apparatus. The fluid flow path extends through the bore of the valve seat member and between the valve seat member and the valve closure member. This fluid flow path is closed when the second frustoconical contact surface is sealed against the first frustoconical contact surface. The screening member is attached to at least one of the valve closure member or the valve seat member, and screens particles from fluid passing through the fluid flow path when the valve closure member approaches the valve seat member.

    摘要翻译: 具有穿过其纵向轴线的阀装置包括阀座构件,阀关闭构件,流体流动路径和筛选构件。 阀座构件包括中空孔和第一截头圆锥形接触表面。 阀关闭构件包括主体和适于密封第一截头圆锥形接触表面的第二截头圆锥形接触表面。 阀关闭构件可沿着阀装置的纵向轴线移动。 流体流路延伸穿过阀座构件的孔并且在阀座构件和阀闭合构件之间延伸。 当第二截头圆锥形接触表面被密封抵靠第一截头圆锥形接触表面时,该流体流动路径是闭合的。 遮蔽构件附接到阀关闭构件或阀座构件中的至少一个,并且当阀关闭构件接近阀座构件时,筛选通过流体流动路径的流体的颗粒。
