Abstract

A valve body with an integral bypass includes a primary valve body portion defining a primary bore extending through the primary valve body portion from a primary upstream end to a primary downstream end, the primary bore defining an axis, the primary bore including a primary upstream bore extending through the primary upstream end and a primary downstream bore extending through the primary downstream end, the primary valve body portion configured to house a valve member between the primary upstream bore and the primary downstream bore; and the bypass seamlessly integrated with the primary valve body portion, the bypass defining a bypass bore, the bypass bore including a bypass upstream bore and a bypass downstream bore, the bypass including a bypass valve body disposed between the bypass upstream bore and the bypass downstream bore.

First claim

That which is claimed is:

1. A valve body with an integral bypass comprising:
a primary valve comprising a primary valve body portion defining a primary bore extending through the primary valve body portion from a primary upstream end to a primary downstream end, the primary bore defining an axis, the primary bore comprising a primary upstream bore extending through the primary upstream end and a primary downstream bore extending through the primary downstream end, the primary valve body portion configured to house a valve member between the primary upstream bore and the primary downstream bore; and
a bypass valve comprising a bypass valve seat seamlessly integrated with the primary valve, an internal surface of the bypass valve defining a bypass bore comprising the bypass valve seat and seamlessly extending between a bypass upstream bore to a bypass downstream bore, the bypass valve seat comprising a bypass valve body disposed between the bypass upstream bore and the bypass downstream bore, the bypass upstream bore extending through the primary upstream end and seamlessly intersecting the primary upstream bore, the bypass upstream bore extending radially outward and axially inward from the primary upstream bore to the bypass valve body relative to the axis, the bypass downstream bore extending through the primary downstream end and seamlessly intersecting the primary downstream bore.

2. The valve body of claim 1 , wherein the bypass downstream bore extends radially outward and axially inward from the primary downstream bore to the bypass valve body relative to the axis.

3. The valve body of claim 1 , wherein:
the primary valve body portion defines a primary valve cavity extending inwards from a bonnet-mounting portion of the primary valve body portion;
the primary valve cavity intersects the primary bore;
the primary valve body portion defines a primary valve seat within the primary valve cavity; and
the primary valve seat is disposed within the primary valve cavity.

4. The valve body of claim 1 , wherein the bypass valve is disposed between an upstream flange disposed at the primary upstream end and a downstream flange disposed at the primary downstream end.

5. The valve body of claim 1 , wherein:
the primary valve body portion comprises a flange disposed at a one of the primary upstream end and the primary downstream end;
the flange is substantially annular to the primary bore;
the flange defines an inner circumferential surface and an outer circumferential surface; and
an identification tab is disposed on the outer circumferential surface and extends radially outwards from the flange.

6. The valve body of claim 5 , wherein the identification tab defines indicia.

7. The valve body of claim 1 , wherein the valve body is a gate valve body.

8. The valve body of claim 1 , wherein:
the bypass bore extends through the bypass valve body; and
the bypass valve defines an integral bypass valve seat disposed within the bypass valve body.

9. A valve assembly comprising:
a primary valve comprising a primary stem and a primary valve member configured to seal against a primary valve seat, the primary valve assembled on a primary valve body portion of a valve body, the primary valve body portion defining a primary bore extending through the primary valve body portion from a primary upstream end to a primary downstream end, the primary bore comprising a primary upstream bore extending through the primary upstream end and a primary downstream bore extending through the primary downstream end; and
a bypass valve comprising a bypass valve seat seamlessly integrated with the primary valve, the bypass valve comprising a bypass stem and a bypass valve member configured to seal against the bypass valve seat, the bypass valve assembled on a bypass valve body, the bypass valve body defined by a bypass of the valve body, the bypass comprising a bypass upstream end and a bypass downstream end, the bypass valve body positioned between the bypass upstream end and the bypass downstream end, the bypass upstream end seamlessly integrated with the primary upstream end and the bypass valve seat, the bypass downstream end seamlessly integrated with the primary downstream end and the bypass valve seat, an integral reinforcement web integrally attached to the bypass valve body and at least one of the bypass downstream end and the bypass upstream end, an internal surface of the bypass valve defining a bypass bore comprising the bypass valve seat and extending between a bypass upstream bore and a bypass downstream bore, the bypass upstream bore extending through the primary upstream end and seamlessly intersecting the primary upstream bore, the bypass downstream bore extending through the primary downstream end and seamlessly intersecting the primary downstream bore.

10. The valve assembly of claim 9 , wherein the primary valve is a gate valve, and the primary valve member is a primary gate.

11. The valve assembly of claim 9 , wherein the valve body is comprised of a monolithic casting formed from a single material.

12. The valve assembly of claim 9 , the bypass is disposed external to the primary valve body portion.

13. The valve assembly of claim 9 , wherein:
the primary bore defines an axis;
the bypass downstream bore extends radially outward and axially inward from the primary downstream bore to the bypass valve body relative to the axis; and
the bypass upstream bore extends radially outward and axially inward from the primary downstream bore to the bypass valve body relative to the axis.

14. A valve body with an integral bypass comprising:
a primary valve comprising a primary valve body portion defining a primary bore extending through the primary valve body portion from a primary upstream end to a primary downstream end, the primary bore comprising a primary upstream bore extending through the primary upstream end and a primary downstream bore extending through the primary downstream end, the primary valve body portion configured to house a valve member between the primary upstream bore and the primary downstream bore; and
