Abstract
A combination steam trap and flow valve assembly including a compact housing having a steam trap chamber, valve chambers, a cover, and a body. The steam trap and valve chambers are integrally formed within the body to create a compact integral assembly. Valve assemblies are received in the valve chambers to control the flow of steam and/or condensate into and out of the assembly. A steam trap mechanism is positioned within the steam trap chamber and the valve unit of the steam trap mechanism being positioned in the cover. The cover is removably attached to the uppermost surface of the body. Passages are provided in the body and cover thereby allowing the flow of steam and/or condensate to the steam trap chamber.
Claims33
A compact combination steam trap and flow valve assembly comprising:
- a hollow housing including a compact body having inlet and outlet ports, and first and second valve chambers, and a trap chamber between and flanked by said valve chambers, said first valve chamber and trap chamber sharing a first common wall of said body, said second valve chamber and trap chamber sharing a second common wall of said body, said common walls being on opposite sides of said trap chamber;
- first and second valve assemblies in said first and second valve chambers respectively for controlling flow therethrough;
- a steam trap mechanism operatively associated with said trap chamber for controlling flow therethrough;
- passages in said body communicating said trap chamber and valve chambers and ports.
A combination steam trap and flow valve apparatus comprising:
- a compact hollow body containing a trap chamber close flanked on opposite sides by first and second valve chambers, said body having a continuous peripheral wall surrounding said first valve chamber and trap chamber and a bight wall chordally connecting opposed parts of said peripheral wall and separating said chambers, said body having an inlet port and an outlet port, said body having passages connecting said trap chamber and first valve chamber and communicating with said inlet and outlet ports;
- a first valve member in said first valve chamber actuable for controlling flow thereto;
- and
- a steam trap mechanism operatively associated with said trap chamber for controlling flow therethrough.
A combination steam trap and flow valve apparatus comprising:
- a peripheral wall substantially coaxially surrounding a trap chamber;
- a peripheral wall substantially coaxially surrounding a valve chamber, said trap chamber and valve chamber peripheral walls having shared longitudinally extending portions;
- a first valve member in said valve chamber actuable for controlling flow therethrough;
- a steam trap mechanism operatively associated with said trap chamber for controlling flow therethrough;
- and
- a flow path through said peripheral walls and connecting said trap chamber and valve chamber.
A combination steam trap and flow valve apparatus comprising:
- a housing comprising a trap chamber, a first valve chamber communicating with said trap chamber, a first port communicating with said first valve chamber, said trap chamber and first valve chamber having length axes in a first plane, said trap chamber and port having length axes in a second plane distinct from said first plane;
- a first valve member in said first valve chamber;
- and
- a steam trap mechanism in said trap chamber.
A combination steam trap and flow valve assembly, comprising a housing including a trap chamber extending longitudinally in said housing, a steam trap mechanism in said trap chamber, an inlet port and outlet port opening sidewardly in said housing, and inlet and outlet valve chambers in said housing and containing respective inlet and outlet valve members, said ports and valve chambers being spaced circumferentially with respect to each other around said trap chamber in alternating fashion.
A combination steam trap and flow valve apparatus, comprising:
- a housing comprising a trap chamber and first and second valve chambers, first and second ports communicating respectively with said first and second valve chambers, said valve chambers having length axes in a common first plane, at least one said port having a length axis acutely angled to said common first plane;
- respective first and second valve members in said first and second valve chambers;
- a steam trap mechanism in said trap chamber, in which said ports have a common length axis acutely angled to said common plane.
