摘要： A fluid operated pinch valve comprises a flexible sleeve fixed at its ends within a valve casing that has a laterally facing opening through which the sleeve may be inserted and replaced without removing the valve casing from the flow line. A casing cover section has a planar sealing face that bridges the opening for sealing engagement with the main casing section, and which also seals against linear sealing flanges on ends of the flexible sleeve.
摘要翻译：流体操作的夹管阀包括在其端部固定在阀壳体内的柔性套管，所述阀壳体具有侧向朝向的开口，套筒可以通过该开口插入和更换，而不从流动管线移除阀门壳体。壳体盖部分具有平面密封面，该平面密封面桥接用于与主壳体部分密封接合的开口，并且还密封柔性套筒端部上的线性密封凸缘。

摘要： A self-aligning valve assembly and a valve plug therefor includes an elastomeric valve plug having an annular outer sealing portion with an annular sealing surface for sealing a drain hole valve seating of a receptacle. A central mounting portion is secured to a pair of telescoped tubes. A flexible diaphragm with a circular convoluted fold integrally connects the mounting portion and the outer sealing portion, and is capable of yielding to permit radial and/or tilting displacement of the outer sealing portion relative to the central mounting portion of the plug to accommodate limited misalignment between the valve tubes and the drain hole.
