Abstract
A hydraulic connector (14) attaches a valve chamber (16) to a flow pipe (P) using a hydraulic clamp (20) to grab the pipe (P) or a flange (F). The valve chamber (16) contains a primary hydraulic ram (26) to telescopically extend a primary seal (28) on the ram (26) to close or open the outlet ports (22) by moving the primary seal (28) to permit flow through valve up flow tubes (34) to a riser (R). Outlet ports (22) in the cap valve (12), or an intermittent pipe (18), permit unrestricted flow while the connector (14) is being installed.
Claims20
A cap valve (12) to shut off a runaway high pressure flow pipe (P), comprising:
- a hydraulic controlled connector (14)
- to attach a cylindrical valve chamber (16), or
- to attach to an intermittent pipe (18) connectable to a cylindrical valve chamber (16),
- to the flow pipe (P) in which the connector (14) has a hydraulic clamp (20) to grab the pipe (P), or to grab a flange (F) on the pipe (P), to hold the cap valve (12) in position;
- and
- outlet ports (22) disposed in the cap valve (12), or in the intermittent pipe (18), above the hydraulic clamp (20) to permit high pressure flow to continue while the connector (14) is being installed on the pipe (P).
A cap valve (12) to shut off a runaway high pressure flow pipe (P), comprising:
- a hydraulic controlled connector (14) to attach a cylindrical valve chamber (16), or
- to attach to an intermittent pipe (18) connectable to a cylindrical valve chamber (16),
- to the flow pipe (P) in which the connector (14) has a hydraulic clamp (20) to grab the pipe (P), or to grab a flange (F) on the pipe (P), to hold the cap valve (12) in position;
- and
- a valve hydraulic cylinder (24) encompassing a primary hydraulic ram (26) which has an adjustable flow primary seal (28) thereon disposed within the cylindrical valve chamber (16) to telescopically close or open access to the outlet ports (22) by moving the primary seal (28) into position to open or block fluid communication through the outlet ports (22).
