Title: Fluid control valve
IPC: F16K31/12
Filed: 1957-03-18
Abstract: 839,692. Valves; fluid-pressure servomotorcontrol systems. OTIS ENGINEERING CORPORATION. March 18, 1957 [Sept. 13, 1956], No. 8844/57. Class 135. A valve comprises a pair of spaced oppositely facing valve seats surrounding an intermediate portion of the through passageway and therebetween a rotatable valve member with an opening therethrough, a fluidpressure operable control frame with a piston movable within a variable capacity pressure chamber provided within a space within the valve body outwardly of the passageway, and means for moving the control frame in opposite longitudinal directions for rotating the valve via cam lugs and cam slots provided on each side of the valve member. The valve, e.g. for oil-well equipment, has a rotary spherical valve 26, which may be conical or cylindrical, seating between two tubular seat members 28, 29, sealingly slidable as at 31 in members 23 connecting the ends of the tubular housing 22 to the flow line. An annular piston 36 actuated by hydraulic pressure at 45, slides sealingly in space 30 between the seats and housing and has a T-connection 54 with an intermediate valve-operating member 53 sliding between the housing and a flat on the valve member and having a slotted connection 58 with a ring 49 loaded by a spring 48 abutting a shoulder 47 on the seat member 29, the shoulder also being loaded by a spring 46 abutting the end of the housing. Seats 28, 29 are urged on to the valve member respectively by pressure at 45 acting on the seat shoulder 51 and by the springs. Valve 26 has on opposite sides a cam groove 59 coating with a pin 60 on member 53 and with a pin 61 on the housing projecting through a slot in member 53, pin 60 being at a greater distance from the rotational axis of the valve and pin 61 so that spring 48 tends to raise members 49, 53, 36 to close the valve. Pressure for moving piston 36 and operating the valve is admitted or exhausted at 45 by e.g. remote manual means or automatic means responsive to a predetermined condition. Should the pipe become severed from its well head support, the weight of tube shears a pin connecting housing 22 to the lower pipe connector whereby the housing and pin 61 move downward to close the valve. In another embodiment, pressure enters the sealed space above piston 36 through a check valve 45 and the pressure is released by breaking a frangible nipple. In a further embodiment, the springs are dispensed with and the valve operated by opposed pistons, pressure in the piston spaces being controlled by a rotary four-way valve and the pins 60, 61 are equally spaced from the valve axis. In another embodiment, one seat is fixed by abutment with the housing shoulder and the other spring loaded on the valve member, the member being operated by telescoping pistons with the controlled pressure acting therebetween. In a further embodiment, both seats are fixed, and the telescoping pistons move within a housing perpendicular to the pipe line. Specification 838,972 is referred to.
