    • A free floating disc check valve is provided by the present application. The check valve includes a seal disc having an integral truncated torroidal shaped portion. The torroidal shaped portion provides structural rigidity to the seal disc to minimize deflection of the disc under higher differential fluid pressures. The torroidal shaped portion of the disc cooperates with finger-shaped projections inside the valve body to limit lateral displacement of the disc relative to the axial flow of the fluid. The torroidal shaped portion and the flat portion of the disc form a cup shape that creates a hydrodynamic force that assists in moving the disc to an opened or closed position. The seal disc is made of an elastomeric material that is coated with a dry film lubricant.
    • 本申请提供了一种自由浮盘式止回阀。 止回阀包括具有整体的截顶状环形部分的密封盘。 环形部分为密封盘提供结构刚性,以使盘在较高差动流体压力下的偏转最小化。 盘的环形部分与阀体内的指状突起配合以限制盘相对于流体轴向流动的横向位移。 环形部分和盘的平坦部分形成杯形,其形成有助于将盘移动到打开或关闭位置的流体动力。 密封盘由涂有干膜润滑剂的弹性体材料制成。

    • A valve that has at least one internal port on a valve core and at least one an internal slot in a valve body. The valve core is biased into a position wherein the port of the valve core is aligned with a sealing surface of the valve body thereby prohibiting fluid flow through the valve. The valve core is slidable such that the port of the valve core becomes aligned with the internal slot of the valve body thereby allowing fluid flow through the valve. Another valve includes a self-aligning valve seat carrier which is pivotably engaged with a valve core member. The self-aligning valve seat carrier engages a sealing surface in a valve body to prohibit fluid flow through the valve, but the valve core is slidable such that the self-aligning valve seat carrier disengages from the sealing surface in order to allow fluid flow through the valve.
    • 阀在阀芯上至少有一个内部端口和阀体中的至少一个内部槽口。 阀芯被偏压到阀芯的端口与阀体的密封表面对准的位置,从而阻止流体流过阀门。 阀芯是可滑动的,使得阀芯的端口与阀体的内部槽对准,从而允许流体流过阀。 另一个阀包括与阀芯构件可枢转地接合的自调心阀座架。 自调心阀座支架接合阀体中的密封表面以阻止流体流过阀,但是阀芯可滑动,使得自对准阀座承载件从密封表面脱离,以允许流体流过 阀门。
