Abstract
Abstract An improved valve assembly for use between flanges basically comprising a valve unit and a housing unit. The valve unit is sized to slidingly fit lengthwise into the housing unit, and includes a slot in a portion of the outer periphery thereof to accommodate the inner end of a valve stem mounted in the housing unit, such that the housing unit valve stem need not be moved lengthwise when the valve unit is being replaced. The housing unit is adapted to cooperate with the flanges to provide a circumferential, secondary metal-to-metal seal therebetween.

Claims Analysis
Total Claims: 18
Claim 1
Independent Claim
286 words
A valve assembly for controlling the flow of fluid between a pair of aligned pipe flanges interconnected by a plurality of circumferentially spaced bolts, comprising: a housing unit, comprising: a housing having opposite end faces, a bore extending therethrough and being adapted to be supported between said flanges by said bolts, said housing being adapted such that each of the end faces thereof circumferentially contacts the end face one of the flanges, thereby providing a metal-tometal seal therebetween; and a first valve stem having an upper and a lower end portion supported in the housing, the lower end portion extending a distance into the bore of the housing; and a valve unit supported in the housing unit, comprising: a valve body having opposite ends and an outer periphery, the outer periphery being sized for the body to be slid lengthwise into the bore of the housing, a portion of the valve body being relieved to accommodate the lower end portion of the first valve stem as the valve unit is slid lengthwise into the housing unit; a valve member supported in a portion of the bore in the valve body for opening and closing the valve assembly; a second valve stem supported in the valve body, having an upper and a lower end portion, the lower end portion being connected to the valve member and the upper end portion being adapted to interconnectingly fit the lower end portion of the first valve stem for transmitting the movement of the first valve stem to the valve member; and seat means in the valve body providing sealing and seating engagement between the valve body and the valve member when the valve member is moved to a closed position.
Claim 2
Dependent Claim
286 words
A valve assembly for controlling the flow of fluid between a pair of aligned pipe flanges interconnected by a plurality of circumferentially spaced bolts, comprising: a housing unit, comprising: a housing having opposite end faces, a bore extending therethrough and being adapted to be supported between said flanges by said bolts, said housing being adapted such that each of the end faces thereof circumferentially contacts the end face one of the flanges, thereby providing a metal-tometal seal therebetween; and a first valve stem having an upper and a lower end portion supported in the housing, the lower end portion extending a distance into the bore of the housing; and a valve unit supported in the housing unit, comprising: a valve body having opposite ends and an outer periphery, the outer periphery being sized for the body to be slid lengthwise into the bore of the housing, a portion of the valve body being relieved to accommodate the lower end portion of the first valve stem as the valve unit is slid lengthwise into the housing unit; a valve member supported in a portion of the bore in the valve body for opening and closing the valve assembly; a second valve stem supported in the valve body, having an upper and a lower end portion, the lower end portion being connected to the valve member and the upper end portion being adapted to interconnectingly fit the lower end portion of the first valve stem for transmitting the movement of the first valve stem to the valve member; and seat means in the valve body providing sealing and seating engagement between the valve body and the valve member when the valve member is moved to a closed position.
Claim 3
Dependent Claim
52 words
The valve assembly of claim 1 wherein the valve body is shaped to include an elongated recess therein intersecting one end thereof and a portion of the Outer periphery thereof to accommodate the lower end portion of the first valve stem as the valve unit is slid lengthwise into the housing unit.
Claim 4
Dependent Claim
36 words
The valve assembly of claim 2 wherein the elongated recess is sized and disposed such that the upper end portion of the second valve stem, including the uppermost end thereof, is positioned in the elongated recess.
Claim 5
Dependent Claim
27 words
The valve assembly of claim 3 wherein a portion of the elongated recess is sized and disposed to journally engage a portion of the second valve stem.
Claim 6
Dependent Claim
79 words
The valve assembly of claim 2 wherein the elongated recess includes a key portion generally adjacent one end of the valve body, said key portion being sized to slidingly receive a portion of the first valve stem in one position of the first valve stem, said key portion thereby cooperating with the first valve stem to assure a proper orientation of the valve unit and the first valve stem upon insertion of the valve unit into the housing unit.
Claim 7
Dependent Claim
62 words
The valve assembly of claim 5 wherein the lowermost end portion of the first valve stem is rectangularly shaped; and wherein the uppermost end portion of the second valve stem includes a recess therein, said recess being shaped to interconnectingly receive the rectangularly shaped end portion of the first valve stem as the valve unit is slid lengthwise into the housing unit.
Claim 8
Dependent Claim
54 words
The valve assembly of claim 1 wherein the first valve stem is defined further to include a flange portion around an intermediate portion thereof, said flange portion forming an upwardly facing surface encircling the fist valve stem, sized and disposed to engage an adjacent portion of the housing, thereby providing a metal-to-metal seal therebetween.
Claim 9
Dependent Claim
37 words
The valve assembly of claim 1 defined further to include a third valve stem journaled in the valve body having an upper and a lower end portion, the upper end portion being connected to the valve member.
Claim 10
Dependent Claim
51 words
The valve assembly of claim 8 wherein the second valve stem is formed integrally with the valve member and extends radially therefrom; and wherein the third valve stem is formed integrally with the valve member and extends radially therefrom, said third valve stem being radially aligned with said second valve stem.
Claim 11
Dependent Claim
24 words
The valve assembly of claim 9 wherein the valve body is split in a horizontal plane extending through the centerline of the valve body.
Claim 12
Dependent Claim
17 words
The valve assembly of claim 1 wherein the valve member is further defined as being spherically shaped.
Claim 13
Dependent Claim
17 words
The valve assembly of claim 1 wherein the valve member is further defined as being disc shaped.
Claim 14
Dependent Claim
48 words
The valve assembly of claim 1 further defined to include an elastomeric liner bonded to a portion of the valve body defined by the bore through the valve body, said liner having a portion thereof sized and disposed to sealingly engage a portion of the second valve stem.
Claim 15
Dependent Claim
42 words
The valve assembly of claim 13 wherein the liner includes a portion sized and disposed to sealingly engage the end face of one of the flanges, and another portion sized and disposed to sealingly engage the end face of the opposite flange.
Claim 16
Dependent Claim
21 words
The valve assembly of claim 13 wherein the liner includes a portion sized and disposed to sealingly engage the valve member.
Claim 17
Dependent Claim
84 words
The valve assembly of claim 11 wherein the valve member is further defined to include a recess in a portion of the exterior surface thereof; and wherein the lower end portion of the second valve stem is defined further as being shaped to interconnecting fit in said recess, the lower end portion being sized smaller than said recess in one direction, so that the valve member will be free to float in an axial direction when the valve member is rotated to one position.
Claim 18
Dependent Claim
91 words
The valve assembly of claim 12 wherein the housing is further defined to include a rim formed adjacent one end thereof, said rim extending a distance radially into the bore of housing, thereby forming a wall encircling the bore in the housing; and wherein the valve body is defined further to inclUde a recess formed in one end thereof adjacent the outer periphery thereof, the recess being sized and disposed to cooperate with said rim in the housing to positively locate the valve body in the housing in an axial direction.
