    Abstract: A valve with an integral means for bleeding internal pressure prior to separation of a bonnet for the valve from its engagement with the valve body, provided by a bore through the valve body. This allows the internal pressure of the valve to equalize with atmospheric pressure prior to complete disassembly of the bonnet from the valve body. The bore through the valve body also serves as a leak detector, by providing a path for fluids passing through the valve to leak to the exterior of the valve body in the event of a failure of the seal between the bonnet and the valve body, which can readily be detected by passersby upon inspection of the exposed end of the bore at the exterior of the valve body.

    Abstract translation: 一种具有一体的装置的阀门,用于在将阀门与阀体接合之前分离出阀盖,以便将阀内部压力释放出来,阀孔由通过阀体提供。 在阀体从阀体完全拆卸之前,这允许阀的内部压力与大气压力相等。 通过阀体的孔也用作泄漏检测器,通过在阀盖和阀体之间的密封件发生故障的情况下提供通过阀门的流体泄漏到阀体的外部的路径, 通过在阀体的外部检查孔的暴露端,可以容易地被路人检测到。
