    A valve actuator, for example a mechanism for imparting motion to a blast furnace evacuation valve, includes a force generator which is coupled to the valve member by a displacement mechanism including a pivotal lever and a pivot arm. The pivotal lever has a pair of angularly related arms with the free end of one arm being coupled to the force generator and the free end of the second arm being coupled to a point on the pivot arm intermediate the ends thereof by a connecting rod or rods. The pivot arm is connected to the valve member and the connecting rod or rods are articulated to both the pivot arm and to the second lever arm which may be telescoping.

    A tank outlet valve is known, having a shut-off valve provided with a sealing surface. a lever interacting with a saddle located at the outlet of the tank and a lever hinged on the tank, a drive member H a control mechanism connecting the drive member with a movable lever and a lever from the rocker arm and rotating around the fixed axis of the rotary lever t-0
    In this drive, however, it makes a big move to fully open the faucet hole. Jq
    The aim of the invention is to reduce the stroke of the actuator to fully detach the 1 outlet .I
    The delivered chain is reached 25 in that the control mechanism is equipped with a spring device acting on a movable lever and made of two telescopically connected parts with spaced between
    They are an elastic element, and not a movable lever is an emphasis, which translates the movement of the arm to the closing.
    In addition, in the valve, one telescopic part of the spring device is hinged on the reservoir, and the other part is hingedly connected on the side of the drive body to the end of the rotary ellchag.
    The swing arm on the rocker side is made of two parts interconnected by the telescopic portions of the spring device.

    FIG. 1 shows an exhaust valve without a spring device in the closed position J in FIG. 2 is the same, in the open position in FIG. 3, a side view in FIG. 1; in fig. 4 - kinematics of cdpana discovery; in fig. 5 seat knot; in fig. 6 - the first installation option spring device} in Fig, 7 - the same, the second option; in fig. 8 - the same, the third variant with valve kinematics; in fig. 9 is a constructive version of the spring device according to FIG. 8; on Aig „10 - another constructive version of the spring device in FIG. 9. The exhaust clan 1 contains a shut-off valve. 2 with an annular seal ™ to the surface 3, which interacts with a saddle 5 located at the outlet of the reservoir 4, and a movable lever 6, LuapHHpHo fixed with the help of axis 7 and support 8 on the reservoir 4, power cylinder 9 with driving element 10 and mechanism control / coupling of the drive unit 10 with a movable lever b - and consisting of the rocker arm 11 and rotating around the fixed axis 12 of the rotary lever 13 o. The valve can also be made with two levers b and rocker arms 11 located symmetrically with respect to the pivot arm 13 (FIG. 3 or with two arms 13 arranged symmetrically with respect to the lever b. Valve 2 is provided with an eye 14 for connection with the lever b using axis 15. The valve 2 with respect to the lever b can make a slight swinging movement. The magnitude of the swing is limited by set screws 16. The axles 7 and 12, as well as the shaft axle 17 of the power cylinder 9 are mounted on brackets 18 "In the tank 4 in front of the saddle 5 for p glancing can be installed by throttle valve 19. Sealing surface 3 valve 2 can be performed directly around the perimeter of its inner surface and on a special metal gasket ring 20 (Fig. The most appropriate surface to perform conical, and matching the surface of the saddle 5 is spherical and convex, then their contact is made around a closed circle. An additional elastic seal 21 can be installed in the valve. In addition, a cooling ve can be brought through channel 2 estvo.v cavity between uplotneny51mi in order to improve the sealing effect and provide a yuschego- possible to prevent premature cooling unloaded elastic sealing and thermal deformation of the metal ring. The control mechanism is provided with a spring device acting through the pivoting lever 13 and the box 11 on the movable lever b. It is made of two telescopic connections of parts 23 and 24 with an elastic element located between them. In the embodiment of the spring device shown in FIG. 6. The elastic element is a compression spring 25. Here, the telescopic part 24 is fixed pivotally by means of an axis 26 on the reservoir, and part 23 is pivotally connected on the side of the driving member 10 to the end of the pivot arm 13. In the embodiment of the spring arrangement shown in FIG. 7, the elastic element is a tension spring 27 which acts on the lengthening of the lever arm 13o. Fig. 8 shows a valve in which the pivoting lever 13 is made of two parts interconnected by the telescopic parts of the spring device. On the movable lever b is the stop 28, which limits the movement of the rocker arm 11 when closing. In the spring device shown in FIG. 9, the elastic element is made. in the form of a package of disk springs 29 arranged around the yaring of the OZO In the spring arrangement shown in FIG. 10, the resilient element is designed as a hydraulic spring including a piston 31, which is affected by oil pressure coming through pipe 32 from the hydroaccumula torus 33. To open the valve, the actuating cylinder 9 is actuated. The retractable actuator 10 acts on the rotary lever 13, which, turning counterclockwise around the axis 12, through the yoke 11 and the movable lever, b moves the check valve 2, in the open position (fig 2) the valve 2 is completely removed from the medium outlet zone from the tank 4, to lock the valve 2 the power cylinder is driven in the opposite direction. Fig. 4 shows the angles o6 and oCg for the open and closed positions of the valve, and it can be seen that the C is significantly greater than Consequently, with the same force on the actuator 10, the force acting on valve 2 has the maximum value in the closed position, and open position - minimal. In this case, the shut-off valve 2t moves along a relatively larger trajectory A, and the drive unit along a small trajectory B, the spring device creates an additional force on the locked valve 2 in the closed position. Its action can replace the action of the power cylinder, if for one reason or another it has failed, In a constructive version of the valve shown in FIG. 8, the lever arm 13 can be lengthened against the action of the elastic element. If, based on what is shown in FIG. 9 bar lines with open lines (ny power cylinder 9 is actuated to close (drive unit 10 is drawn into the cylinder), then the rocker arm 11 and lever 13 rotate C in the form of an arc of a circle to the closed position of the valve
    [2]
    2. When the valve-2 is seated on the saddle, the indicated cons are in the position indicated by the point o. Prior to this phase, the atce element did not come into action. When the valve 2 and lever 6 are stationary, lever 13 and the rocker arm 11 continue to move. Their pivotally connected ends move to the trajectory D in the form of an arc of a circle, the radar arm of which is radar 11. Since starting point Q, the trajectory D is removed from curve C, then the movement of these ends is possible only if there is an elastic ep & tape that does not prevent lengthening of the lever. This movement continues to the dead point when the beam 11 and the lever arm 13 associated with it are aligned. After this point, the resilient element promotes movement. The displacement is interrupted at the time of contact of the rocker arm 11 with the stop 28 - point b. In this case, the presence of the elastic element allows an emergency boost. the pressure in the tank to the valve opens without the fate of the valve. The valve has a short stroke for the actuator, which reduces oil consumption for controlling it. Claims 1. Inlet valve for tanks with crude gas from mine
