摘要： A butterfly valve having a composite, reinforced seat, the valve having a one piece body defining a radially inwardly extending annular rib, the valve seat being a U-shaped annular member of a generally resilient material and having a radially outwardly opening channel which engages the rib of the valve body to provide an interlocking engagement between the valve seat and the valve body, the seat including a series of generally U-shaped structural members made of a material more rigid than the resilient material of the seat, the U-shaped member being bonded to the seat, the U-shaped members being spaced sufficiently to permit distortion of the seat so that it can be inserted in the valve body.

摘要： An apparatus for inserting a resilient valve seat (100) into a valve body (20). the valve body being of a type having a radially inwardly projecting annular rib (22) which defines a bore (24) through the valve body, the valve seat being generally annular and having an annular web portion (102), a first annular flange portion (104) projecting radially outwardly from a first end of the web portion and a second annular flange portion (106) projecting radially outwardly from a second end of the web portion to define an annular, radially outwardly opening channel (108) for receiving the rib, the apparatus including a frame (10) which has an opening and having a plate (14) for positioning a valve body adjacent the opening such that the bore in the valve body and the opening in the frame are in register, a plunger assembly slidably mounted in the frame, the plunger assembly having a mounting head (66) and a plurality of circumferentially spaced grabbing elements secured to the mounting head, the grabbing elements including projections (88,90) to engage one of the annular flange portions of the valve seat such that as the mounting head is moved in a given direction in the frame, the grab elements engage the rib in the valve body resulting in a distortion or folding of the valve seat such that the engaged annular flange portion can pass through the bore defined by the rib.
摘要翻译：一种用于将弹性阀座（100）插入阀体（20）中的装置。所述阀体是具有径向向内突出的环形肋（22）的类型，所述环形肋（22）通过所述阀体限定孔（24），所述阀座大致环形，并具有环形腹板部分（102），第一环形凸缘部分（104），其从所述腹板部分的第一端部径向向外突出;以及第二环形凸缘部分（106），其从所述腹板部分的第二端部径向向外突出，以限定用于接纳所述肋条的环形径向向外的开口通道（108）该装置包括具有开口的框架（10），该框架具有用于将阀体邻近开口定位的板（14），使得阀体中的孔和框架中的开口对准，柱塞组件可滑动地所述柱塞组件具有安装头（66）和固定到所述安装头的多个周向间隔开的抓握元件，所述抓取元件包括突出部（88,90），以接合所述环形阀座的凸缘部分使得当安装头沿框架中的给定方向移动时，抓斗元件与阀体中的肋接合，导致阀座的变形或折叠，使得接合的环形凸缘部分可以通过由肋限定的孔。
