摘要： A pipe tool positioning system for efficiently inserting, positioning, and orienting a tool for use within a pipe. The pipe tool positioning system generally includes a sleeve with a receiver opening adapted to receive and removably retain a tool such as a grinder or the like. The sleeve includes radially-offset bladders extending outwardly from its outer surface. Each of the bladders may be individually inflated and/or deflated to aid in positioning of the tool within a pipe. A control unit may be provided with controllers for individually controlling each of the bladders. A camera may also be included adjacent to the sleeve to feed a display included with the control unit. By utilizing the present invention, various tools may efficiently be inserted and positioned for use within a pipe.

摘要： A control system for a fluid actuated control member is disclosed which uizes a pair of electrically controlled servo valves to control the supply of servo pressure fluid to a control valve piston. The pair of servo valves are electrically controlled such that, under normal conditions, one of the servo valves is operative to supply the servo pressure signal, while the other servo valve remains in an inert, open position. Upon the detection of a malfunction in the operative servo valve, electrical switches render the malfunctioning valve inert and transfer the operative capabilities to the second servo valve. The hydraulic control system does retain 100% of its performance capabilities following a malfunction of the initial servo valve.

摘要： A system for limiting the torque of a multiple hydraulic system power drive unit wherein plural hydraulic motors are connected to a common torque-summing output device. The system has at least two separate hydraulic circuits, with there being a pressure-limiting valve in each circuit which controls the porting of motor pressure to a low pressure return line and which sums the motor pressure existing in the fluid circuit in which the valve is positioned and the pressure in the other hydraulic circuit whereby the maximum pressure of the fluid delivered to the motor cannot exceed one-half the maximum pressure when both circuits are active to limit the torque applied to the torque-summing output device. In a system having two separate hydraulic circuits, the pressure-limiting valve has a first pressure-responsive area exposed to motor pressure in one circuit and a second pressure-responsive area exposed to pressure in the other circuit, with the latter pressure-responsive area being one-half the first pressure-responsive area.

摘要： A redundant, dual-fail/operate fly-by-wire control system actuates a redundant tandem piston actuator (10) to provide a single composite output evidenced by movement of a piston rod (12). The basic fault-tolerate actuation system consists of dual hydraulic primary actuators, quadruplex electrical control loops (14-17), and control servo valves (22-25). A failure management system connects to the actuation system by means of lines (18-21) to control the servo valves (22-25). The four control loops (14-17) connect to a pilot controller that provides pilot individual input signals to amplifiers (26-29) for each of the control loops.

摘要： Method and apparatus for hydraulically controlling subsea well equipment, such as valve operators, connectors, and other hydraulically actuated devices, with a significantly reduced number of hydraulic pressure source lines from the surface to the subsea location of said well equipment. The apparatus includes a multi-mode subsea switching valve having a plurality of module-like sections, each section having an inlet port, a vent port and a plurality of outlet ports. When installed, this valve preferably is located near the subsea well, and a source of hydraulic pressure and a plurality of hydraulic switches, all located on a surface vessel or other surface facility, are connected to the valve's inlet ports by means of a relatively small number of hydraulic pressure source lines. A relatively large number of hydraulic outlet lines interconnect the valve's outlet ports and the subsea well equipment so that in each of its functional modes the valve directs fluid pressure to a different set of subsea devices. The valve is switched from one mode to another by a pulse of hydraulic pressure exerted on an operator apparatus that is connected to the valve's flow control element, and these modes are changed in a manner such that the position of the valve's flow control element is always known.
