PNEUMATIC DRIVE, JET MOTOR (VERSIONS) AND ELECTROPNEUMATIC CONTROL UNIT Russian patent published in 2002 - IPC

Abstract RU 2178842 C1

FIELD: oil and gas producing and processing industries. SUBSTANCE: pneumatic drive has successively connected electropneumatic control device including electromagnets, air distributors connected with working medium source under pressure, reversible jet motor whose shaft is connected through mechanical reduction gear with link-screw turning gear and drive output shaft, manual doubler, limit switches. Turning mechanism body is made in the form of central body with two covers. Turning mechanism body has through guide rectangular recess accommodating carrier with sliding nut threaded with lead screw connected with device absorbing kinetic energy of drive movable components. Drive has a stopper. Jet motor is made with changeable nozzle units, or according to the other version, in the form of central bushing with two arms whose nozzles are directed to the same side. Electropneumatic control device including electromagnets, limit switches, air distributors is made in one unit. Device input shaft runs through body and cover of explosion-proof chamber, and movable permanent magnets are connected with inlet shaft through setup gearing and located outside of explosion-proof chamber. Electropneumatic control device has gas flow rate regulator whose inlets are respectively connected with air distributors outlets, and their outlets are connected with inlet pipes of jet motor. Air distributor has separate channel whose inlet is connected with compressed gas source, and outlet, with inlet of servo valve of air distributor. Said drive is designed for remote and local control of valve of gas-and-oil product pipelines. EFFECT: higher operating reliability. 8 cl, 14 dwg
