Valve

Claim 2

A valve comprising, a housing, a first conduit and a second conduit extending into the housing and being axially aligned with each other and each having one end positioned in the housing and longitudinally spaced from each other forming an opening therebetween, a sleeve within said housing slidably telescoping with said one end of the first and second conduits in a sealing relationship whereby when the sleeve covers the opening, flow is permitted through the conduit but is prevented from entering the housing, means for longitudinally moving the sleeve, flow control means pivotally supported for rotation into and out of said opening and including a tubular member contoured for engagement with the sleeve, means for rotating said flow control means into said opening, and seal means for providing a seal between the tubular member and the sleeve when the tubular member is rotated into the opening and engaged by the sleeve said tubular member being in telescoping engagement with said sleeve.

Claim 3

The apparatus of claim 1 wherein the control means is pivotally supported about an axis that is perpendicular to the longitudinal axis of said conduits.

Claim 4

The apparatus of claim 1 wherein at least one of said ends of the first and second conduit in the housing is removable thereby increasing the width of the opening for allowing internal removal of the sleeve for changing seals in the valve.

Claim 5

The apparatus of claim 1 wherein the flow control means comprises a sector of a hollow ball.

Claim 6

The apparatus of claim 1 wherein the flow control means is a flow barrier whereby when the control means is positioned in the opening, the end of the first conduit is closed.

Claim 7

The apparatus of claim 1 wherein the flow control means is a regulating valve comprising, longitudinally extending opening meanS in the tubular member, and said seal being on the sleeve whereby the amount of the opening means covered by the seal means may be varied by longitudinal movement of said sleeve.

Claim 8

The apparatus of claim 1 wherein the flow control means includes two flow control elements, either one of which may be rotated into said opening.

Claim 9

The apparatus of claim 7 wherein one of the control elements is a check valve in one direction and the second is a check valve in the second direction of the fluid flow.

Claim 10

The apparatus of claim 7 including means for rotating the two flow control elements separately.

Claim 11

The apparatus of claim 7 wherein the two flow control elements are connected together.

Claim 12

The apparatus of claim 9 wherein said rotating means includes, first and second trunnions extending into the housing and axially aligned, each of said trunnions supporting each of the flow control elements, the first of said trunnions connected to one of the flow control elements for rotating said one element, and the second of the trunnions connected to the other flow control element for rotating said other element.

Claim 13

The apparatus of claim 7 wherein one of the flow control means includes a removable orifice plate.

Claim 14

The apparatus of claim 7 wherein one of the flow control means includes a check valve.

Claim 15

A valve comprising, a housing, an inlet conduit and an outlet conduit extending into the housing and being axially aligned with each other and each having one end positioned in the housing and longitudinally spaced from each other forming an opening therebetween, a sleeve within said housing slidably telescoping with said one end of the inlet and outlet conduits in a sealing relationship whereby when the sleeve covers the opening, flow is permitted through the conduits but is prevented from entering the housing, means extending through the housing engaging the sleeve for longitudinally moving the sleeve relative to the said ends, flow control means pivotally supported for rotation into and out of said opening, said means including an arcuate portion carrying a tubular member, said tubular member sized and contoured for telescopic engagement with the sleeve when the flow control means is rotated into the opening, means for rotating said tubular member into said opening for engagement with the sleeve, and seal means for providing a seal between the tubular member and the sleeve.

Claim 16

A valve comprising, a housing, an inlet conduit and an outlet conduit extending into the housing and being axially aligned with each other and each having one end positioned in the housing and longitudinally spaced from each other forming an opening therebetween, a sleeve within said housing slidably telescoping with said one end of the inlet and outlet conduits in a sealing relationship whereby when the sleeve covers the opening, flow is permitted through the conduits but is prevented from entering the housing, means extending through the housing engaging the sleeve for longitudinally moving the sleeve relative to the said ends, flow control means pivotally supported for rotation into and out of said opening, said means including an arcuate portion carrying a tubular member, said tubular member sized and contoured for telescopic engagement with the sleeve when the flow control means is rotated into the opening, means for rotating said tubular member into said opening for engagement with the sleeve, and seal means for providing a seal between the tubular member and the sleeve.

Claim 17

The apparatus of claim 14 wherein the seal means is on the tubular member and including, an access opening in the housing for changing the tubular member.

Claim 18

The apparatus of claim 15 wherein one of the ends of the conduits in the housing is removable thereby increasing the width of the opening for allowing internal removal of the sleeve for changing seals in the valve.

Claim 19

The apparatus of claim 14 wherein the flow control means is a regulating valve comprising, longitudinally extending opening means in the tubular member, and said seal means being on the sleeve whereby the area of the opening means covered by the seal means may be varied by longitudinal movement of said sleeve.
