摘要： A choke valve with a power system operated via a single hydraulic line. The sleeve of the choke valve is operated by a carrier mounted through an eccentric pin and guide track arrangement to open and close the valve with the rotation of a valve drive shaft. A power shaft is driven by a clutch plate, ratchet connected to a drive clutch plate, in turn, operated by the shaft of an hydraulic actuator. The valve actuator creates an incremental step sensing of its full sixteenth turn movement by closing a fluid exhaust port and causing back pressure in the hydraulic line to occur. The actuator is reset by a pre-loaded torsion bar. Reset of the actuator also ratchet resets the drive clutch plate.

摘要： The invention is an improved self-centering, floating metal seal to be used in combination with a ball valve which controls the flow of fluid in a conduit. The ball valve includes a valve body which has a bore extending therethrough and which also has an inlet and an outlet which are axially aligned and adapted to be mechanically coupled to the conduit. The valve body also has an aperture therein. The ball valve also includes a spherical valve member having a port the axis of which is alignable with the axis of the bore of the valve body and a stem having an inner end mechanically coupled to the spherical valve member and an axially outer end which extends through the aperture of the valve body. The ball valve further includes a device for forming a seal between the aperture of the valve body and the stem. The improved self-centering, floating metal seal includes a metal ring which has a planar surface and a contoured surface which is adapted to contact the spherical surface of the valve member and which is axially aligned with the bore of the valve body and is disposed adjacent to the spherical valve member. The seal also includes a metal piston which has a first planar surface which is disposed adjacent to the planar surface of the metal ring and a second planar surface. There is a difference in the dynamic sealing areas of the piston and metal ring so that the upstream pressure mechanically seals the ball valve.

摘要： A new and improved valve apparatus having an operating mechanism sealed in such a manner that the fluid pressure urging thereon produces offsetting or balancing forces to enhance ease of valve operation. To accomplish the force balancing, the flow closure means is continuously sealed to the valve housing and seat to produce the desired pressure responsive surfaces. By balancing the pressure forces, movement of the valve closure element between the open and closed positions with a minimum of operating force is accomplished. In addition the operating mechanism tubular flow closure element and valve seat having a plurality of opposed radially disposed flow opening are arranged so that the controlled flow through the openings into the seat impinges on itself to prevent flow cutting or erosion of the valve seat. When the flow closure element moves to the closed position, it activates a protected second seal on the seat to block flow throuh the flow openings.

摘要： A fluid flow control valve especially adapted for use during well drilling operations as a drilling choke is disclosed. A replaceable ported seat and movable tubular flow control element cooperate to control flow through the angled body valve housing. The flow closure mechanism is operating fluid pressure balanced for ease of valve operation during extreme pressure working conditions. Internal flow control working parts of the valve are rugged in construction and assemblage. The portions of the valve subject to wear or flow erosion are also easily replaced when required. An indicator is arranged to signal incipient failure of the replaceable parts of the valve in order that they may be replaced prior to the occurrence of a major failure.

摘要： A shut-off valve in a fluid line closes by spring pressure and incorporates a control chamber wherein pressurized control fluid acting on a piston opens the valve in opposition to the spring pressure. A control system for the shut-off valve comprises a 3-way actuator pilot of the present invention in cooperation with a monitor pilot. The actuator pilot has a valve spool and four ports, namely, a supply port connected to a source of pressurized control fluid, a pilot port connected to the monitor pilot, a control port connected to the control cylinder of the shut-off valve, and an exhaust port for venting the control chamber of the shut-off valve. When the control system is in service and the monitor pilot senses an undue change in the pressure in the fluid line, the monitor pilot vents the actuator pilot to shift the valve spool therein to cut off the control fluid from the control port and simultaneously to place the control port in communication with the exhaust port to cause the shut-off valve to close.

摘要： Similar transfer units are disclosed for launching pig balls into a pipeline and for receiving the pig balls from a downstream portion of the pipeline, each of the transfer units including a hollow housing providing an axially aligned manually or hydraulically operable valve member and valve seat for closing off a magazine which is inclined from horizontal to permit gravity transfer of the pig balls, the hollow housing being otherwise shaped to facilitate transfer of the pig balls. With a pair of the transfer units being connected with a pipeline, the launching unit includes controlled plungers for regulating passage of individual pig balls into the pipeline while the receiving unit at the downstream portion of the pipeline is arranged for directing the pig balls into the receiving unit. A magazine housing for each unit is separable from the hollow housing to facilitate replacement of the valve seat.

摘要： A shut-off valve in a fluid line closes by spring pressure and/or line pressure and incorporates a control chamber wherein pressurized control fluid acting on a piston opens the valve in opposition to the spring pressure and/or line pressure. A 3-way actuator pilot normally places the control fluid in communication with the control cylinder but when vented cuts off the control supply fluid and releases the pressurized control fluid from the control chamber to cause the shut-off valve to close by spring pressure and/or line pressure. A monitor pilot responsive to pressure changes in the fluid line incorporates a relief valve and opens the relief valve by cam action to vent the actuator pilot whenever the pressure in the fluid line makes a predetermined departure from a normal pressure range.

摘要： Reset means to advance a valve spool from a first valve seat to a second valve seat in opposition to exceedingly high biasing fluid pressure comprises a manually rotatable actuating means in screw threaded engagement with the body of the pilot valve. With the manually operable actuator at its retracted position, means is manually operated to operatively connect the manual actuator to the valve spool to permit advance of the manual actuator to drive the valve spool from the first valve seat to the second valve seat against the resistance of the biasing fluid pressure. In consequence of the advance of the valve spool to the second valve seat, an opposite fluid pressure progressively rises to a normal operating range at which it dominates the biasing fluid pressure to hold the spool against the second valve seat independently of the manual actuator and this rise of the opposite fluid pressure to the normal operating range automatically releases the connecting means to give the valve spool freedom for subsequent retraction by the biasing fluid pressure in the event that the dominating fluid pressure falls below its normal operating range.
