Valve arrangement for a pressurizable vessel
First Claim
1. A valve arrangement for a pressurizable vessel, comprising a valve member mountable on a vessel for movement relative thereto, said valve member having passage means which extends in part along said valve member and which is movable together with the latter, said valve member having an exterior portion;
- and a valve-actuating assembly removably mountable on the vessel, including a fitting having a passage and surrounding said valve member with clearance at the exterior of the vessel, further including a housing in said passage of said fitting and provided with an interior passageway in which said exterior portion of said valve member is movably received, and means provided within said interior passageway of said housing for displacing said valve member between an open position in which said passage means communicates the vessel interior with the clearance so as to permit fluid flow between the interior and exterior of the vessel, and a closed position in which said fluid flow is prevented.

Abstract
A valve arrangement for a pressurizable vessel includes a valve member mountable on a vessel for movement relative thereto. The valve member is formed with a passage which extends over part of the length of the valve member. A valve-actuating assembly is removably mountable on the vessel. The assembly includes a fitting surrounding the valve member with clearance at the exterior of the vessel, a housing movably mounted within the fitting, and force-transmitting elements partially received within the housing and operative for displacing the valve member between an open position in which the passage communicates the vessel interior with the clearance so as to permit fluid flow between the interior and exterior of the vessel, and a closed position in which such fluid flow is prevented.

12. A valve arrangement for a pressurizable vessel, comprising a valve member mountable on a vessel for movement relative thereto, said valve member having passage means which extends in part along said valve member and which is movable together with the latter;
- a valve-actuating assembly removably mountable on the vessel, including a fitting having a passage and surrounding said valve member with clearance at the exterior of the vessel, means for displacing said valve member between an open position in which said passage means communicates the vessel interior with the clearance so as to permit fluid flow between the interior and exterior of the vessel, and a closed position in which such fluid flow is prevented, and further including a housing in said passage of said fitting and having an interior passageway therein, said housing being removably mountable on said valve member so that the latter is partially received into said interior passage-way and having a portion surrounded by said fitting in sealing relationship, said housing having a flange portion in overlying relationship with said fitting; and
spring means intermediate said housing and said fitting for urging the latter towards the vessel so as to sealingly contact the same, said urging means having opposite ends in respective abutment with said flange portion and said fitting.
- a valve-actuating assembly removably mountable on the vessel, including a fitting having a passage and surrounding said valve member with clearance at the exterior of the vessel, means for displacing said valve member between an open position in which said passage means communicates the vessel interior with the clearance so as to permit fluid flow between the interior and exterior of the vessel, and a closed position in which such fluid flow is prevented, and further including a housing in said passage of said fitting and having an interior passageway therein, said housing being removably mountable on said valve member so that the latter is partially received into said interior passage-way and having a portion surrounded by said fitting in sealing relationship, said housing having a flange portion in overlying relationship with said fitting; and

13. A valve arrangement for a pressurized vessel, comprising a valve member having an interior threaded portion mounted in a wall of the vessel for turning and axial movement relative to the latter, said interior threaded portion of said valve member being provided with a groove which cuts through and extends along an outer surface of said interior threaded portion, said groove being open into the interior of the vessel, said valve member having an exterior threaded portion;
- and a valve actuating assembly removably mountable on the vessel and including a fitting surrounding said valve member with clearance at the exterior of the vessel provided within said housing for engaging said exterior threaded portion of said valve member and operative for displacing the latter between an open position in which said interior threaded portion is so located that said groove of said interior threaded portion also communicates with said clearance so as to permit fluid flow between the exterior and interior of the vessel, and a closed position in which said interior threaded portion is so located that the wall of the vessel prevents said communication of said groove of said interior threaded portion with said clearance whereby said fluid flow between the exterior and interior of the vessel is prevented.
