    An actuator for actuating valves and the like which comprises a pair of opposed cylinders, the axes of which are generally perpendicular to a valve stem. Pistons in the cylinders are connected to the valve stem by toggle links, the pistons being resiliently urged toward the center of the assembly which corresponds to a closed valve position. To open the valve, a fluid, such as air, is introduced between the pistons, so as to move them away from their rest (valve closed) positions. A handwheel is provided to manually open the valve by moving the pistons from their rest positions. A solenoid controlled pneumatic valve may be used to control the supply of air to the actuator. Either a failure in air pressure or an electrical failure will result in the pistons being urged to the rest positions and also result in closing the connected valve, i.e., the failure mode.

    2. The mechanism according to claim 1, characterized in that it is provided with a manual backup drive consisting of a hollow rod passed through one of the cylinders and a piston located in it, at one end of which a flywheel is mounted and the other is thickened, and a telescopic the ski is located in the hollow stem of the inner stem, at the free end of which a slot is cut that encloses the stem of the locking member, and the inner stem is made cooperating with the piston of another cylinder.
    The invention can be used in valve industry. The known locking device drive mechanism, which includes two spring-loaded pistons connected to the pressure source of the medium and located opposite, and two levers, one ends of which are pivotally connected to the stem of the locking member, and the other end of each of the levers is hingedly connected to each of the pistons. . her . The known device is characterized by the complexity of the design and due to this lack of reliability in operation, since two independent cylinders cannot be combined in one package and therefore require several connections with the pressure source, as well as the absence of a manual drive doubler. The purpose of the invention is to simplify 1 construction and increase reliability in operation. . The goal is achieved by the fact that the spring-loaded pistons are placed in the housing with the formation of a chamber between their ends, we take the chamber connected to the source of pressure of the medium and the valve stem is located in it. In addition, the drive mechanism is equipped with a manual backup drive consisting of a hollow rod, passed through one of the cylinders and a piston located in it, at one end of which a flywheel is mounted, and the other is thickened, and is telescopically located in the hollow rod of the internal rod. the end of which has a slot encompassing the stem of the locking member, with the inner stem interacting with the piston of another cylinder. The drawing shows the proposed device. The drive device includes a housing 1 with end caps 2,; made in the form of two cylinders 3 and j, in which, respectively, pistons 5 and 6 are fitted with springs 7 and 8, respectively. Between the ends of the pistons in the housing chamber A is formed, through which the rod 9 of the closure member passes. The levers 10 and P. are hinged to the rod 9. The opposite ends of the levers are connected to the pistons. Control medium is introduced into chamber A or of pressure source 12 through switching device 13 intended to control the flow of medium into chamber A and out of it. On the rod 9 is fixed switch 14 position. The device works as follows. The control fluid from the source 12 through the switch 13 is introduced into the chamber A, the pressure of the medium acts on the pistons 5 and 6 and spreads them from the center against the action of the springs 7 and 8. Under the action of the levers 10 and P the rod 9 rises and the locking member 15 opens. Diverting the control medium from chamber A changes the action of the drive mechanism to the opposite. In the event of a malfunction of the medium source or switching its device 13, the pistons are moved towards each other, and the locking member 15 is closed. A handwheel actuator is provided in the device, consisting of a hollow stem 16 with an internal thread passing through the cover 2. A flywheel 17, 3 is attached to one end of this stem and the other end of the stem is thickened.
    A rod 18 with an external thread is inserted into the hollow rod 16, on the outer end of which a slot 19 is made for the rod 9 to prevent the rod 18 from rotating. The output end of the bar 18 rests on the piston 6. By rotating the flywheel 17, the rod 18 moves to the piston 6 against the force of the spring 8. The reverse (counterbalancing) force moves the thickened end of the stem t6, raises the stem 9 by means of levers 10 and 11, and opens the locking member 15.
    The technical and economic effect of the invention is to simplify the structures and increase the reliability of the device.
