Abstract
This invention is directed to improvements in valve control housings, specifically those used in the consumer, commercial, and industrial markets to house gas control valves. The present invention includes a plastic body, the body being molded to accept valve components, an integral sealant being over-molded to the plastic body, and a case, the plastic body being sealingly surrounded by an outer case.
Claims19
A gas control valve housing comprising:
- a body formed with a gas inlet port, a gas outlet port, and at least one cavity gas transmissibly connected therebetween, the at least one cavity configured to accept at least one valve component for controlling gas transmission;
- a casing having an inlet opening and an outlet opening, wherein the casing surrounds the body and wherein the inlet opening is substantially gas transmissibly aligned with the gas inlet port and the outlet opening is substantially gas transmissibly aligned with the gas outlet port;
- and
- a sealant, the sealant being over-molded and positioned between the body and the casing including between the inlet port and the inlet opening and between the outlet port and the outlet opening.

A gas control valve housing comprising:
- a plastic body formed with a gas inlet port, a gas outlet port, and at least one cavity gas transmissibly connected therebetween, the at least one cavity configured to accept at least one valve component for controlling gas transmission;
- a metal casing, the casing being formed from an extruded metal tube, a metal top plate and a metal bottom plate, the extruded tube having an inlet opening and an outlet opening, wherein the casing surrounds the body and wherein the inlet opening is substantially gas transmissibly and axially aligned with the gas inlet port and the outlet opening is substantially gas transmissibly and axially aligned with the gas outlet port;
- and
- a sealant, the sealant being over-molded to the plastic body and positioned between the body and the casing including between the inlet port and the inlet opening and between the outlet port and the outlet opening.

A gas control valve housing comprising:
- a plastic body formed with a gas inlet port, a gas outlet port, and at least one cavity gas transmissibly connected therebetween, the at least one cavity configured to accept at least one valve component for controlling gas transmission, and a valve seat to accept a face of the valve component;
- a metal casing, the casing being formed from an extruded metal tube, a metal top plate and a metal bottom plate, the extruded tube having an inlet opening and an outlet opening, wherein the casing surrounds the body and wherein the inlet opening is substantially gas transmissibly and axially aligned with the gas inlet port and the outlet opening is substantially gas transmissibly and axially aligned with the gas outlet port;
- and
- a sealant, the sealant being over-molded to the plastic body and positioned between the body and the casing including between the inlet port and the inlet opening and between the outlet port and the outlet opening.
