A mounting adaptor for coupling a gas pressure regulator outlet to a gas meter inlet includes a plate having through-bores alignable with internally threaded blind holes which surround the meter inlet in the meter wall. The plate has a planar surface surrounding the outlet opening of the regulator and is adapted for contact engagement with a planar surface on the meter exterior wall surrounding the inlet opening. A groove in the planar surface of the plate holds a sealing ring to effect a seal. In an alternate construction, a tube extends from the plate into the meter inlet opening and an annular groove on the tube exterior holds a sealing ring for engagement with a cylindrical wall extending into the meter from the inlet opening.

Gas pressure regulator coupling arrangement

A diaphragm-type gas pressure regulator wherein the valve subassembly is constructed as a drop-in unit. The valve subassembly includes a diaphragm lever and a plunger valve. A seat disk is inserted in a cavity at a first end of the plunger valve and the rounded pivot end of the lever is inserted in a groove at the other end of the plunger valve. The plunger valve is then inserted into a valve guide and a lever pin is installed through the guide and the lever, thereby capturing the subassembly. This subassembly is then placed into the regulator body and a mounting plate of the valve guide is screwed down into the regulator body. The lever is lifted up and its actuator end is inserted through an opening at the bottom of the valve stem of the regulator's diaphragm assembly. An orifice member is then threadedly installed into the regulator body inlet, the end of the orifice member having a valve seat which becomes seated in the end of the plunger valve guide. In an alternate embodiment, the orifice is formed as part of the plunger valve guide.
