    专利说明:

    The invention relates to an arlaturostroy and can be used on large-diameter pipelines for the transport of toxic corrosive media that require reliable compaction.
    A valve is known that contains a locking disc, which is pressed against the saddle by a driving device comprising two lever mechanisms Tj.
    The drawbacks of the device - the complexity of the design and lack of reliability of the overlap of the pipeline.
    Closest to the technical, the essence and the achieved result to the invention is a valve containing a spherical body and size. It has a hollow plug installed on two diametrically opposed axes, one of which is associated with a rotational drive and equipped with a locking disc mounted on a yoke connected to the semi-axle connecting rods with the ability to move in the direction towards the saddle, the locking disk is fixed on the yoke by means of the central sleeve, passed through the response hole of the rocker and spring-loaded. Regarding it 2.
    A disadvantage of the known device is its lack of reliability due to the impossibility of providing hermetic sealing of the saddle.
    The aim of the invention is to increase the reliability of the valve.
    This goal is achieved by the fact that the ball valve for large diameter pipelines contains a spherical body and a hollow tube placed on it installed on two diametrically opposite semi-axes, one of which is connected (G with a turn actuator and fitted with a locking disk mounted on the beam, connected to the axle shaft and, connected with connecting rods with the possibility of moving in the direction towards the seat, the locking disk being fixed on the yoke by means of the central bushing passed through the connecting hole of the rocker arm and dinner in relation to it, the ends of the yoke are equipped with levers, and in the semi axes there are free hollows with grooves through which the guide levers are passed, besides, the sockets are made in the bald box, and the cork is provided with a cantilever plate with mounted on it the ability to interact with the rocker sockets with two conical locking pins, on the guide arms and in the body there are lock protrusions, and on the cork mounted on the swivel
    axis x with the ability to interact with the protrusions of the guide levers two spring-loaded hook, provided with rollers that interact with the locking protrusions of the housing.
    5 Figure 1 shows the ball
    valve with locking disc in open position, front view in cross section; figure 2 - ball valve, side view in cross section; fig.Z - the same, with zapornym disk in the position before closing, turned 90; 4, Td in the position of pressing the locking disc to the seat.
    5 The ball valve contains a spherical body .1 and a hollow plug 2 placed in it, mounted on two diametrically opposite semi-axes x 3 and 4, one of which is 3
    associated with the rotational drive 5. Paul
    the plug 2 is provided with a locking disc 6 mounted on the rocker arm 7 connected to the axles 3 and 4 with connecting rods 8 and 9. The locking disc 6 is fixed on the rocker arm 7 by means of a spring-loaded central sleeve 10. The floor of the stopper 2 is integral with part of the pipe 11, which in the open position of the valve is part of the pipeline inside the valve.
    The ends of the rocker arms 7 are provided with guide levers 12 and 13, and in the semi-axes x 3 and 4, fingers 14 and 15 are freely located with grooves 16, through which guide arms 12 and 13 are passed.
    In the yoke 7, the sockets 17 are made, and the stopper 2 is provided with a cantilever plate 18 with mounted on it
    Q interoperability with the sockets 17 with two conical pin holders 19. On the guide levers 12 and 13 and in the housing 1, locking projections and 21 are made, and
     On the plug 2, two spring-loaded hooks 24 and 25 are mounted on the rotary axes x22 and 23, which cooperate with the stop lugs 20 of the guide levers 12 and 13. The spring-loaded hooks 24 and 25 are equipped with rollers 26, which interact with the stop lugs 21 of the housing 1. Ball valve operation performed as follows.
    Drive 5 turns carried out
    5 opening or closing the ball valve. At the same time, in the open position of the valve, a part of the pipe 11 is a part of the pipeline along which the remeasurement of the medium 0 Dy occurs.
    In order to close the valve, turn the plug 5 with the locking disc 6 by 90 using the actuator & (Ho of the actuator 5). At the same time, the kinematic chain moving the disc 6 and formed by the rocker 7 connected to the rods 8 and 9 of the guides the levers 12 and 13 are rigidly connected to the hollow concave 2 using tapered locking pins 19 and spring-loaded hooks 24 and 25. Consequently, the locking disk 6 rotates rigidly together with the stopper 2, which eliminates the displacement of the disk b relative to the axis of rotation under the action of the cut-off working environment, and therefore The pore disk 6 is installed with a strictly opposite sealing surface of the seat. For the water of the locking disk 6, it is guided to the sealing surface of the saddle rigid with an ст stima formed by the rocker 7 and the direction of the arms 12 and 13, which can only slide along the locking protrusions 20 and 21 and then only move along the axis of the seat. This prevents any possible rotation of the disk 6 around the fingers 14 and 15. When the valve closes, the connecting rods 8 and 9 are located along the axis of the saddle in a position of stable equilibrium Tate which seal is created without affecting the actuator 5 Cremet of the locking disc would not rigidly associated with a yoke 7 and the voltage L yuschimi levers 12 and 13, and elastically coupled to the yoke 7, which avoids the misalignment during assembly. Thus, when rotated 90 hollow tube 2, the guiding levers 12 and 13 come into contact with the corresponding locking tabs 20 and 21 and cannot be further rotated; further rotation of the hollow plug 2 for closing the valve causes the automatic release of the conical locking pins 19. To improve the adhesion of the locking disc b and the rocker arm 7 with the stopper 2 when the valve is in position or when closing, there are two spring-loaded hooks 24 and 25, which engage with the projections 20 of the guide levers 12 and 13. The hooks 24 and 25 are equipped with rollers 26, up and acting with the locking of the protrusions and 21 when they are released. The technical and economic efficiency of the invention consists in increasing the reliability of the valve by precisely fitting the locking disk onto the seat due to the fact that the locking disk is placed at the end of its rotation exactly opposite the sealing surface of the seat and with further rotation moves strictly radially to the saddle due to rotation of the connecting g those. during locking the locking disc is located all the time coaxially with the valve seat.
