    摘要： A pneumatic pinch valve having a main body, a piston supporting a plunger, and a detachable headpiece for receiving a portion of compressible tubing between the plunger and a contoured surface of the headpiece is disclosed. A first safety cap which may restrict access to the plunger when the valve is operated and a manual override handle which may open the plunger are also provided. The pneumatic pinch valve is opened by the injection of gas through an air inlet port to a pneumatic chamber. The headpiece and plunger are configured to compress a portion of flexible tubing in a manner which reduces or eliminates damage to the tubing even after repeated open/close cycles. Further, the pinch valve may be installed onto an existing process system without disruption of fluid flow. Also disclosed is a manual version of the pinch valve.

    摘要翻译： 公开了一种气动夹管阀，其具有主体，支撑柱塞的活塞和用于接收柱塞与头架的轮廓表面之间的可压缩管道的一部分的可拆卸头盔。 还提供了第一安全帽，其可以在操作阀时限制对柱塞的进入，并且还提供可以打开柱塞的手动超控手柄。 气动夹管阀通过气体通过进气口喷射到气动室来打开。 头盔和柱塞构造成以减少或消除对管道的损坏的方式来压缩柔性管道的一部分，即使在重复的打开/关闭循环之后。 此外，夹管阀可以安装在现有的工艺系统上而不破坏流体流动。 还公开了夹送阀的手动版本。

    摘要： A check valve includes a valve body defining an internal chamber and a valve seat disposed within the internal chamber adjacent to one of the first and second ends of the valve body. A poppet is mounted for linear movement along a poppet axis within the internal chamber between the first and second ends of the valve body and has a predetermined cross-sectional shape in a direction transverse to the poppet axis, a peripheral rim defining a movement guiding surface, a frustoconical surface provided in one axial end of the poppet and oriented in a direction toward the one end of the valve body, a sealing bead disposed on the frustoconical surface, and a predetermined plurality of passages formed in a predetermined pattern through at least one of the peripheral rim and the frustoconical surface in open communication with an opposed axial end of the poppet.
