Abstract
Provided is a plug valve. The plug valve, in one example, includes a valve body having inlet and outlet seal inserts disposed within a central chamber thereof, a plug member disposed, in the central chamber, and a bonnet disposed at least partially within the central chamber and removably coupled to the valve body. The plug valve, in this example, further includes one or more substantially axial compression members positioned between the bonnet and the inlet and outlet seal inserts.
Claims20
A plug valve, comprising:
- a valve body having an inlet port, an outlet port and a central chamber extending between the inlet port and the outlet port;
- an inlet seal insert disposed within the central chamber and having an inlet bore extending there through and substantially aligned with the inlet port;
- an outlet seal insert disposed within the central chamber having an outlet bore extending there through and aligned with the outlet port;
- a plug member disposed in the central chamber the plug member moveable between an open position to facilitate fluid flow through the plug valve and a closed position to block fluid flow through the plug valve;
- a bonnet disposed at least partially within the central chamber and removably coupled to the valve body;
- and
- one or more substantially axial compression members positioned between the bonnet and the inlet and outlet seal inserts.

A well system, comprising:
- a wellbore penetrating a subterranean formation;
- an oil/gas service tool assembly positioned within the wellbore;
- and
- a plug valve in fluid communication with the oil/gas service tool assembly, the plug valve including;
- a valve body having an inlet port, an outlet port and a central chamber extending between the inlet port and the outlet port;
- an inlet seal insert disposed within the central chamber and having an inlet bore extending there through and substantially aligned with the inlet port;
- an outlet seal insert disposed within the central chamber having an outlet bore extending there through and aligned with the outlet port;
- a plug member disposed in the central chamber, the plug member moveable between an open position to facilitate fluid flow through the plug valve and a closed position to block fluid flow through the plug valve;
- a bonnet disposed at least partially within the central chamber and removably coupled to the valve body;
- and
- one or more substantially axial compression members positioned between the bonnet and the inlet and outlet seal inserts.

A method of assembling a plug valve, comprising:
- providing a valve body having an inlet port, an outlet port and a central chamber extending between the inlet port and the outlet port;
- disposing an inlet seal insert within the central chamber and having an inlet bore extending there through and substantially aligned with the inlet port;
- disposing an outlet seal insert within the central chamber having an outlet bore extending there through and aligned with the outlet port;
- inserting a plug member in the central chamber, the plug member moveable between an open position to facilitate fluid flow through the plug valve and a dosed position to block fluid flow through the plug valve;
- removably coupling a bonnet to the valve body and at least partially within the central chamber, wherein one or more substantially axial compression members are positioned between the bonnet and the inlet and outlet seal inserts prior to removably coupling the bonnet.
