摘要： High localized loading, galling, and high torque forces have been generally eliminated or greatly reduced in a two ferrule tube fitting assembly through suitable modification of the rear ferrule so as to redirect the reaction forces acting between the front ferrule and the drive nut. The rear ferrule has a cylindrical interior wall that closely surrounds the tube end and is provided on the interior cylindrical wall with a circumferentially continuous radial recess that is located between the nose and rear wall of the rear ferrule. The rear ferrule also has a radially external wall that is substantially conical and additionally shaped to extend radially outward toward the enlarged diameter portion or flange of the rear ferrule. The rear ferrule further includes a contoured face on the rear driven surface of the ferrule that engages the drive surface of the drive nut.
摘要翻译：通过对后套圈的适当改进，两个套圈管接头组件通常消除或大大降低了高局部负载，磨损和高扭矩力，以便重定向作用在前套圈和驱动螺母之间的反作用力。后套圈具有紧密围绕管端的圆柱形内壁，并且在内圆柱形壁上设置有周向连续的径向凹部，其位于后套圈的前后壁之间。后套圈还具有径向外壁，其基本上为圆锥形并且另外成形为朝向后套圈的扩大直径部分或凸缘径向向外延伸。后套圈还包括在套圈的后驱动表面上的与驱动螺母的驱动表面接合的轮廓面。

摘要： A thermally and chemically inert valve seat is provided. The valve seat includes a sharp edge located on the periphery of the valve seat body, wherein the edge digs into a surface within the valve body to secure the valve seat. The valve seat may be case hardened to provide additional strength and sealing ability. The inner diameter of the valve seat may be flush against the valve fluid passageway, thereby decreasing the contact area between the diaphragm and the valve seat.
摘要翻译：提供了一种热和化学惰性的阀座。阀座包括位于阀座主体周边上的锋利边缘，其中边缘挖入阀体内的表面以固定阀座。阀座可以表壳硬化以提供额外的强度和密封能力。阀座的内径可以与阀流体通道齐平，从而减小隔膜和阀座之间的接触面积。
