    Abstract: The gate valve has a body portion with coaxial inlet and outlet openings in the side walls and valve body chamber with opposed converging valve seats. A wedge member has a body portion with a depending wedge shaped gate portion that is movable vertically into a valve chamber within the body portion to control the flow of fluid through the valve body portion. A cover member is secured to the upper face of the valve body and has an elongated chamber communicating with the valve chamber in which the wedge member moves vertically. A guide pin and valve stem are positioned within a cover chamber in spaced parallel relation to each other and on opposite sides of the longitudinal axis of the gate portion of the wedge member. The wedge member body portion has a longitudinal passageway on one side of the gate portion through which the guide pin extends. The wedge member body portion has a second vertical threaded passageway on the other side of the wedge member gate portion through which the threaded valve stem extends. Rotation of the valve stem moves the wedge member vertically within the chamber of the cover in a manner that the gate portion of the wedge control the flow of fluid through the valve body chamber. The valve body, because of the offset stem configuration, is relatively short in length and may be positioned between closely adjacent pipe flanges.

    Abstract translation: 闸阀具有在侧壁中具有同轴入口和出口的主体部分和具有相对的会聚阀座的阀体腔。 楔形构件具有主体部分，其具有垂直楔形门部分，其可垂直移动到主体部分内的阀室中，以控制通过阀体部分的流体流动。 盖构件固定到阀体的上表面，并且具有与阀室连通的细长室，楔形构件垂直移动。 引导销和阀杆定位在盖室内，彼此间隔开并且在楔形构件的门部分的纵向轴线的相对侧上。 楔形件主体部分具有在浇口部分的一侧上的纵向通道，导向销延伸穿过该纵向通道。 楔形件主体部分在楔形件门部分的另一侧上具有第二垂直螺纹通道，螺纹阀杆通过该通道延伸。 阀杆的旋转使得楔形构件在盖的腔室内垂直地移动，楔形件的门部分控制流体通过阀体腔室的流动。 由于偏置阀杆构造，阀体的长度相对较短，并且可以位于相邻的管凸缘之间。

    Abstract: A riser assembly for the connection of an underground gas line to a meter or other device includes a tubular polyethylene adapter having its lower end connected to the upper end of a polyethylene tubular member, which is connected at its lower end to the underground pipeline. A connecting sleeve of corrosion resistant, electrically nonconductive material, such as a combination of fiber glass and epoxy resin, maintains the upper end of the adapter in spaced relationship to the lower end of a metallic tubular member, which is connected at its upper end to the meter or other device. A polyethylene support sleeve surrounds the outer surface of the mutually connected end portions of the adapter and the lower tubular member. The adjacent ends of the lower portion connecting sleeve and upper portion of the adapter are maintained in fluid-tight engagement by the combination adapter support sleeve and resilient O-ring secured in the upper portion of the adapter. The riser assembly can also include a metallic outer support conduit surrounding the riser assembly and extending from the connection between the lower end of the metallic upper tubular member and the upper end of the connecting sleeve to a point at the lower end of the lower polyethylene tubular member near the connection to the underground pipeline. The outer support conduit may be closed for storage or transport at its upper end by an epoxy seal and at its lower end by a resilient end plug.

    Abstract translation: 用于将地下气体管线连接到仪表或其它装置的提升管组件包括管状聚乙烯适配器，其下端连接到聚乙烯管状构件的上端，该聚乙烯管接头的下端连接到地下管道。 耐腐蚀，不导电的材料（例如玻璃纤维和环氧树脂的组合）的连接套管将适配器的上端保持与金属管状构件的下端成间隔开的关系，该金属管状构件的上端连接到 仪表或其他设备。 聚乙烯支撑套筒围绕适配器和下管状构件的相互连接的端部的外表面。 下部连接套筒和适配器的上部的相邻端部通过组合适配器支撑套筒和固定在适配器的上部中的弹性O形环保持流体密封的接合。 提升管组件还可以包括金属外支撑导管，其围绕提升管组件并且从金属上管状构件的下端与连接套筒的上端之间的连接部延伸到下聚乙烯管的下端 会员靠近地下管道连接。 外部支撑导管可以被封闭以在其上端由环氧树脂密封件存储或运输，并且在其下端由弹性端塞输送。
