摘要： A two stage gas pressure regulator with a body housing having a gas inlet and a gas outlet, and a common interior wall dividing the body housing into two chambers forming two pressure reducing stages. Respective intersecting fluid passageways through the common interior wall communicate the first stage to the second stage and provide a gauge pressure tap on the body housing, the intersecting passageways meeting at an intersection point within the common interior wall. Respective diaphragms are provided for each stage, and a cover has a vent venting the volume defined between the cover and the second stage diaphragm. A small passageway is provided in a common cover wall between the two stages, the small passageway being sized to suitably vent both cover portions above the respective diaphragms through the vent while eliminating overpressurization of the second stage in the event of pressure regulating failure of the first stage. A diaphragm actuated lever arm includes a slotted end with the slot matching a stepped gas flow controlling disc. The disc is stepped to match the lever end slot so as to trap the disc within the lever slotted end. The inlet orifice in one or both of the regulator stages can be formed by casting and without further machining or additional orifice components.
摘要翻译：具有主体壳体的两级气体压力调节器，其具有气体入口和气体出口，以及将主体壳体分成形成两个减压阶段的两个室的公共内壁。通过公共内壁的相交的相交流体通道将第一阶段连接到第二阶段，并且在主体外壳上提供表压压力分接头，相交的通道在公共内壁内的交叉点处相交。为每个级提供相应的隔膜，并且盖具有排出盖和第二级隔膜之间限定的体积的通风口。小通道设置在两级之间的公共盖壁上，小通道的尺寸适于通过排气孔适当地排出相应隔膜上方的两个盖部分，同时在第一段压力调节失效的情况下消除第二级的过压阶段。隔膜致动杠杆臂包括开槽端，其中狭槽与阶梯式气体流量控制盘匹配。盘被阶梯以匹配杆端槽，以将盘捕获在杠杆开槽端内。一个或两个调节器级中的入口孔可以通过铸造形成，而不需要进一步加工或附加的孔组件。
