摘要： A check valve comprises a housing defining a valve seat thereon and a valve member reciprocally mounted in the housing to normally engage the seat for blocking fluid flow therepast. Two pairs of split retaining members are mounted in axially spaced relationship on a stem of the valve member and are expanded axially thereon by a compression coil spring for biasing the valve member to its closed position. A stop member is secured on an end of the stem of the valve member to prevent movement of one pair of the retaining members therepast. A slot is formed axially through the stop member and extends partially in the stem of the valve member to expose an end of the spring.

摘要： A cross-connection valve, with upstream and downstream valving, which prevents backflow from contaminating the source of liquid is provided with field serviceability features by arranging the upstream valving and backflow discharge passageway means on an access door that normally serves as part of the valve body. A tool is arranged to enter through the discharge passage to hold the upstream valving in assembled condition on the access door, to permit field servicing for repair or replacement of the upstream valving, when the access door is open, and the downstream valving is also accessible for field servicing through the opening for the access door.
摘要翻译：具有上游阀门和下游阀门的交叉连接阀门通过在通常用作阀体的一部分的检修门上布置上游阀门和回流排放通道装置来提供现场可维护性特征，其具有防止回流污染液体源的交叉连接阀。工具被布置成通过排放通道进入以将组装状态的上游阀保持在检修门上，以便当检修门打开时允许现场维修维修或更换上游阀门，并且下游阀门也可接近通过门的开口进行现场维修。
