摘要： The present invention discloses an active intelligent wellbore pressure control system, which includes a ground multi-parameter online monitoring system (86), a rotary blowout preventer (1), a wellhead back pressure compensation manifold, an automatic plugging material filling device (62), a drilling device, an MPD intelligent control system (87), a remote monitoring and control system (88), and a high-precision hydraulic calculation system (105). The present invention provides a wellbore pressure control thought of “plugging and control integration”, improves the pressure resistance of a formation by circularly plugging while drilling, realizes active control of a wellbore pressure, effectively broadens a “drilling safety density window” of the formation, reduces the requirements on the pressure control precision of a wellbore pressure control device, solves the problem that a conventional MPD technology cannot deal with the situation that the “drilling safety density window” of the formation is extremely narrow or even zero, and expands the application range of the MPD technology.

摘要： A pressure regulating module for regulating the pressure of a first fluid using a reference pressure of a second fluid. A pressure transfer assembly including a piston slidably disposed within a cylinder bore between a control fluid chamber and a reference fluid chamber is dimensioned to provide a predefined radial clearance between at least a portion of the outer side wall and the inner circumferential surface of the housing along a predefined axial length of the main body. The predefined radial clearance and predefined axial length are dimensioned to control the flow rate and amount of fluid along one or more fluid communication passages formed between at least a portion of the piston and the housing inner circumferential surface from one or more high pressure fluid zones to a lower pressure fluid zone which can include a leak and/or weep orifice directing fluid to a drain and/or vent circuit.

摘要： Adjustment of loop-powered pneumatic process control device interfaces is disclosed. A disclosed example interface for use with a pneumatic process control device includes a power input to scavenge power from a loop power control signal associated with the process control system, a movement controller to cause movement of an actuator powered by the loop power, where the actuator is operatively coupled to a movable control input associated with the process control device, and a calibrator to read position feedback of the actuator during the movement to calculate a positional error, where the calibrator is to adjust a set point of the loop power control signal based on the positional error to control the actuator.

摘要： A valve controls the discharge of fluid stored under pressure in cylinders (4) and includes a body (2) with a fluid inlet hole (3), a fluid outlet hole (5), and a sealing shaft (6) whose movement, determined by release means (7), opens or closes the fluid passage The release means (7) includes at least one pneumatic actuation hole (11) with non-return valve (12) and a hermetic chamber (10) associated with said sealing shaft (6), a pressure cartridge (8) of compressed gas associated with an electric and manual actuator (9) external to the body (2) and the hermetic chamber (10), which, transmits the motion to a rod (15) linked to said sealing shaft (6). A spring (16) tends to keep the sealing shaft (6) closed, when the pressure is zero or when the cylinder (4) is empty.

摘要： A system includes a first valve fluidly connected to a first vessel and a second valve fluidly connected to a second vessel. The first valve includes a body and a piston. The body includes first and second ports and a bore having a longitudinal axis. The first port is in communication with the bore and an interior of the first vessel. The second port is in communication with the bore, the second valve, and an atmosphere exterior to the first vessel. The piston is movable along the longitudinal axis of the bore. A first position of the piston blocks the first port; a second position of the piston allows fluid communication between the first and second ports. The first valve is configured so that fluid pressure from the second valve, communicating through the second port, urges the piston to the second position.

摘要： A vacuum valve is provided with opening pressure setting means that sets a set value of a fluid pressure in a primary side passage beyond which communication is opened and forcible opening means that forcibly opens communication regardless of the fluid pressure in the primary side passage. The opening pressure setting means includes a spring receiver fixed to a stem, a compression coil spring having a lower end supported by the spring receiver, and an adjustment screw, movable in the axial direction, that presses the upper end of the compression coil spring. The forcible opening means includes a piston inserted onto the stem 5 under the spring receiver so as to be movable upward and downward and piston driving means that moves the piston and the spring receiver upward integrally by moving the piston upward using compressed air.

摘要： A pressure regulator for liquid media includes a through-flow path which extends between two connections for a medium-conducting line. The through-flow path is equipped with a valve seat which can be released or closed by a closing element that is mounted in a movable manner between a closing position and a release position. A wear of the closing element and/or the valve seat can be monitored during ongoing operations using a wear sensor device.

A housing cover defines an upper cavity and comprises a cover fluid inlet and a cover fluid outlet. The cover fluid inlet is in fluidic communication with the base fluid outlet between the upper cavity and the lower cavity, and the cover fluid outlet provides external access from the upper cavity. A diaphragm is disposed between the housing base and the housing cover. A pinch plate is disposed in the lower cavity and comprises a pinch point disposed opposite the pinch structure. A pinch tube is in fluidic communication between the base fluid inlet and the base fluid outlet in the lower cavity.
