Abstract

A valve assembly for a fluid system is disclosed. The valve assembly includes a housing having a base portion and a stem portion. A valve core is disposed in a cavity formed in the stem portion. The valve core is in fluid communication with a port formed in a component of the fluid system through passageways and the cavity of the base portion. The valve assembly further includes a valve disposed in a cavity formed in the base portion. The valve is configured to selectively permit a flow of fluid through at least one of the passageways, and thereby the valve assembly. The valve is configured to provide hermetic sealing to selectively isolate the valve core from the component of the fluid system.

First claim

What is claimed is:

1 . A valve assembly for a fluid system, comprising:
a housing having a base portion and a stem portion, the base portion including an aperture extending longitudinally therethrough and configured to receive a component of the fluid system having a fluid flowing therethrough, wherein the housing includes at least one passageway in fluid communication with a port provided in the component of the fluid system; a valve core disposed in the stem portion to selectively permit a flow of the fluid of the fluid system therethrough; and a valve disposed in the base portion to selectively permit the flow of the fluid of the fluid system through the at least one passageway, wherein, when the valve militates against the flow of the fluid from the fluid system through the valve assembly, the valve core is in a closed position to provide a double seal, wherein, when the valve permits the flow of the fluid from the fluid system into the valve assembly, the valve core is in an open position, and wherein the valve is accessible from outside the housing regardless of the position of the valve core.

2 . The valve assembly of claim 1 , wherein the base portion is generally perpendicular to the stem portion.

3 . The valve assembly of claim 1 , wherein the base portion is positioned relative to the stem portion at an angle greater than or less than 90 degrees.

4 . The valve assembly of claim 1 , wherein the base portion is axially aligned with the stem portion.

5 . The valve assembly of claim 1 , wherein the valve is in threaded engagement with the housing.

6 . The valve assembly of claim 1 , further comprising a sealing element disposed between the valve and the housing to form a substantially fluid-tight seal therebetween.

7 . The valve assembly of claim 1 , further comprising a retaining element to militate against removal of the valve from the housing during pressurization.

8 . The valve assembly of claim 1 , wherein the housing includes a sealing surface adjacent said passageway.

9 . The valve assembly of claim 8 , wherein the sealing surface of the housing is one of linear conical shaped and curved conical shaped.

10 . The valve assembly of claim 8 , wherein the sealing surface of the housing has a sealing radius in a range of about 0.0 to about 3.0.

11 . The valve assembly of claim 8 , wherein the valve includes a seat extending axially from a first end thereof to selectively engage the sealing surface of the housing.

12 . The valve assembly of claim 11 , wherein the seat has an included angle in a range of about 30 degrees to about 90 degrees.

13 . The valve assembly of claim 11 , wherein a sealing surface of the seat of the valve has one of a conical, frustoconical, and hemispherical shape.

14 . The valve assembly of claim 11 , wherein a sealing surface of the seat has a coating treatment deposited thereon.

15 . The valve assembly of claim 14 , wherein the coating treatment is a tin plating.

16 . The valve assembly of claim 11 , wherein at least one of an end of the valve opposite the seat and the housing are deformable after installation of the valve into the valve assembly to militate against removal of the valve from the housing during pressurization.

17 . The valve assembly of claim 11 , wherein an angle of a sealing surface of the seat of the valve is substantially the same as an angle of the sealing surface of the housing.

18 . The valve assembly of claim 11 , wherein an angle of a sealing surface of the seat of the valve is different from an angle of the sealing surface of the housing.

19 . The valve assembly of claim 11 , wherein a difference between the angle of the sealing surface of the seat of the valve and the angle of the sealing surface of the housing is in a range of about 0.5 degrees to about 30 degrees.

20 . A valve assembly for a fluid system, comprising:
a housing having a base portion and a stem portion, the base portion including an aperture extending longitudinally therethrough and configured to receive a component of the fluid system having a fluid flowing therethrough, wherein the housing includes at least one passageway in fluid communication with a port provided in the component of the fluid system; a valve core disposed in the stem portion to selectively permit a flow of the fluid of the fluid system therethrough; and a valve disposed in the base portion, wherein the valve is configured to provide hermetic sealing to selectively isolate the valve core from the component of the fluid system, wherein, when the valve militates against the flow of the fluid from the fluid system through the valve assembly, the valve core is in a closed position to provide a double seal, wherein, when the valve permits the flow of the fluid from the fluid system into the valve assembly, the valve core is in an open position, and wherein the valve is accessible from outside the housing regardless of the position of the valve core.
