摘要： In the stem set configuration for a double block and bleed plug valve, the improvement provides an operator which can be significantly shorter and more compact than conventional operators for such valves. The invention makes use of a novel nesting of the threading section whereby a conventional female thread is replaced by a nested male thread surrounded by the translation section. The translation section, in turn, houses the indication section inboard of the nested male threads thereby compacting three functions into one location. This design lends itself nicely to investment casting technology obviating conventional machine shop practices. The invention also combines by use of a long plug stem pin, the plug connection and L slot functions into one location. The input function still remains separate, however, combining ultimately all functions in only three discrete locations and what appears at this time to be the ultimate compacted or nested arrangement.

摘要： An improved bleed system for a double block and bleed plug-type valve which employ a safety check valve which automatically shuts off bleed system flow upon ruptures or upon an inadvertently open manual bleed valve during normal plug valve operation. An integral component combines the safety check valve and other bleed system components in a unitary device which is especially resistant to plumbing damage incidents.
摘要翻译：一种用于双块和泄放塞式阀的改进的排气系统，其采用安全止回阀，其在断裂时自动关闭泄放系统流量，或者在正常的旋塞阀操作期间无意中打开手动放气阀。一体式组件将安全止回阀和其他排气系统组件组合在一体的设备中，特别适用于管道损坏事故。

摘要： A unified block integral bleed system for use with valves such as plug-type valves wherein pressure release flow occurs through a manifold port mounting arrangement which accesses upstream, downstream and body cavity portions of the valve and provides atmosphere taps as well without external piping. Such a manifold integral body bleed system provides internal flow channels and is preferrably configured as a separate external unit which can be retrofitted to existing valve installations in the field. The manifold bleed system may be attached to the valve, such as by welding, or may be located at a position remote from the valve.
摘要翻译：一种统一的块式积分排放系统，用于阀门，例如插塞式阀门，其中通过歧管端口安装装置发生压力释放流，该歧管端口安装装置接触阀门的上游，下游和体腔部分，并且在没有外部管道的情况下也提供气氛抽头。这种歧管整体式泄放系统提供内部流动通道，并且优选地被配置为可以在现场的现有阀门装置中改装的单独的外部单元。歧管泄放系统可以例如通过焊接附接到阀，或者可以位于远离阀的位置。
