摘要： A pressure relief valve includes a valve body having an axial inlet port and a lateral outlet port, with an enlarged bore extending between such ports. A valve bonnet attached to the valve body slidably guides a poppet for movement between closed and open positions for closing and opening the inlet port. A seal ring positioned in the bore adjacent the inlet port sealingly surrounds the poppet in its closed position. The seal ring is axially compressed between a retainer ring and a backup surface, and a ring nut threaded in the bore compressively engages the retainer ring. The ring nut is located entirely on the inlet port side of the outlet port so it does not inhibit flow to the outlet port when the poppet is open. A poppet guide bore in the bonnet extends inwardly from a bonnet end surface, and a pair of concentric recesses of different diameters also extend into the bonnet from the end surface. One recess receives a seal ring positioned in surrounding sealing relationship with the poppet, and the other recess receives a push-in retainer for retaining the seal ring in its recess. A small diameter stem on the poppet extends into a bonnet spring receiving bore and has a rounded end received by a conical recess in a guide disc. Close fitting cylindrical locating surfaces are used for providing accurate concentricity between the bonnet and body, and between the retainer ring and the bore.

摘要： An inverted bellows valve has a two-piece stem interconnecting the valve and actuator for reciprocating axial movement of the stem tip. Tapered surfaces are advantageously utilized between cooperating elements for self-centering the valve assembly. An annular gland disposed along the exterior of the valve stem has concentric inner and outer O-rings which permit the stem to float and compensate for misalignment. A wobble collar is also disposed in abutting engagement with the stem to compensate for uneven spring forces which could otherwise cock the stem. The bellows subassembly is removable in one piece to facilitate maintenance and replacement.

摘要： A bellows valve has inlet and outlet passages in fluid communication with a valve chamber on opposite sides of a valve seat. An elongated valve stem has a first end adapted for selective sealing engagement with the valve seat, and a second end of the stem is operatively connected with an actuator assembly. An expansible bellows has a first end secured to the valve stem and a second end sealingly connected to a closing member so that a portion of the valve stem is surrounded thereby. The closing member engages an open end of the valve body and includes an arcuate or rounded sealing protrusion or bead adapted for mating, sealing contact with a generally planar surface on the valve body. The sealing bead facilitates a reduction in or complete elimination of the use of lubricant between the valve body and a bonnet nut, and this, in turn, promotes clean valve operation by removing a potential contaminant. A tapered surface on the closing member faciitates alignment with the valve body, and clearances between the closing member, valve bonnet, and bonnet nut also facilitate alignment of the assembled valve components.
摘要翻译：波纹管阀具有与阀座的相对侧上的阀室流体连通的入口和出口通道。细长的阀杆具有适于与阀座选择性密封接合的第一端，并且杆的第二端与致动器组件可操作地连接。可膨胀的波纹管具有固定到阀杆的第一端和密封地连接到闭合构件的第二端，使得阀杆的一部分被围绕。封闭构件接合阀体的开口端并且包括弧形或圆形的密封突起或凸珠，其适于配合，与阀体上的大致平坦的表面密封接触。密封珠有助于减少或完全消除在阀体和阀帽螺母之间的润滑剂的使用，这又通过去除潜在的污染物来促进清洁阀的操作。关闭构件上的锥形表面便于与阀体对准，并且关闭构件，阀帽和阀盖螺母之间的间隙也有助于组装的阀构件的对准。
