    The invention relates to metallurgy, in particular, to valves for discharging molten metal from a vessel, such as a ladle, and integral parts for it.
    The purpose of the invention is to simplify repair and maintenance, increase the service life of the shutter.
    Fig. 1 shows a shutter, a cut, a drain channel perpendicular to the axis of rotation of the rotor; figure 2 is a view of And figure 1; FIG. 3 shows a closure at the junction of the bottom and the wall of the container; figure 4 - the shutter in the wall of the vessel; figure 5 is the same, the drain channel with a bend; on fig.b - the same. cylinder shaped rotor; 7 - the same. the end of the rotor is straight; on Fig - shutter on the bottom of the tank in the melt; figure 9 is a section bB in Fig.8; in fig. 10 - shutter, cross section; in fig. 11 - stator, axonometrics; on Fig rotor, axonometric; in fig. 13 - capacity with a stator and a rotor moved along the axis, a longitudinal section.
    The rotary shutter 1 is located in the corner zone between the lining 2 of the tank bottom and the refractory lining 3 of the tank wall as part of the refractory lining of the metallurgical tank in the zone of the melt (figure 1). Lining 2 of the bottom protects the metal bottom of the tank, and lining 3 - the wall 4 of the tank. The bottom has an opening 5 for discharging the melt downwards, and a metal side wall 4 opening 6 for accessing the rotary valve 1 from the side and driving it. Thus, the lining 2 and 3 of the bottom and walls of the reservoir are replaced at the location of the butterfly valve 1 by its parts. The rotor is made with a cone XI GJ Yu 00 O Yu

    a separate section serving as a locking body, and this section is pressed against the corresponding cone-shaped seat 7 of the stator 8. The stator 8 consists of two parts, one of which has a vertical outlet channel 9; its elongation downward passes through the metal bottom of the tank in the form of a pouring pipe 10 and is made together with this part. Thus, the stator 8 simultaneously forms a circulating discharge. The other part 11 of the stator is made in the form of a hollow cone to accommodate the end of the rotor 12 facing the drive. The rotor 12 has a through channel 13 which communicates with the outlet channel 9 of the stator 8. The inlet 14 and the outlet 15 of the through channel 13 of the rotor 12 are located on its forming surface. The outlet 16 and the inlet 17 of the stator 8 are arranged approximately vertically one above the other, so that in the open position of the rotor 12 there is provided a vertical and direct melt flow for vertical casting. On the drive side, a drive head 18 is connected to the rotor 12 to rotate around a horizontal axis 0-0, entering protrusion 19 in the form of a bar into the recess of the locking body, made in the form of a transverse slot 20. Due to this, torque can be transmitted. On the outer edge, the drive head 18 surrounds the drive end of the rotor 12 with an annular flange 21. The drive head 18 is connected to the outside through the universal joint 22 of the drive shaft 23 of the drive 24. Using a spring package 25 and through an axial bearing fixed to the drive shaft 23, the drive head 18 is pressed in the direction of the stator to abut the conical section of the rotor 12 to the corresponding conical seat 7 of the stator 8. An elastic coupling 26 is placed between the axial bearing and the drive 24. The drive shaft 23, spring package 25, is placed on the drive shaft 23 The actuator 18, universal joint 22, elastic coupling 26 and actuator 24 are supported by a support 27, which has the ability to pivot down on a hinge 28 mounted outside the tank, for which you need to open the quick-release lock 29. Due to this, the rotor 12 is easily available for replacement. The stator 8 can be made of a block completely inserted through the wall 4 with a recess for mounting the drive end of the rotor 12, the drive head 18, the universal hinge 22 and the first part of the drive shaft (FIG. 3). Draft pipe 10, which may be composed of two parts, a and b, is fitted
    from the bottom through the recess 5 in the metal bottom of the tank and is held on it by means of the clamping device 30. Seal the gap between the stator 12 and
    the discharge pipe 10 is carried out by pressing the sealing mass through the sealing pipe 31 into the cavity surrounding the gap 6 in which the conical head of the discharge pipe is located.
    0 The through channel of the 13-rotor 4 runs not along a straight, but at an angle (Fig. 4), so that the inlet 14 of the rotor 12 is located on its end surface facing the melt, and the outlet 15 is located on the generatrix of the surface. As a consequence, the outlet channel 9 of the stator 8 is formed by practically only one segment entering the outlet port 16. In addition, between the conical seat 7
    0 stator 8 and a conical section of the rotor 12 is inserted sleeve 32 slip. Stat.or 8 has an outer flange 33 adjacent to the outer side of the metal wall 4 of the tank, on which the support plate 27 exerts an influence on the outside.
    The rotor 12 may be spherical at the end (FIG. 5), and the stator seat 7 may have a similar shape. The inlet 14 and the outlet 15 of the rotor 12 are located on its forming surface. Through channel 13 of the rotor 12 in this case is somewhat curved.
    Butterfly valve 1 can be placed in the corner between the refractory lining
    5 2 the bottom of the tank and the refractory lining 3 walls as part of the total lining of the tank, in the zone of the melt (Fig.6). The bottom has an aperture of 5 to release down the metal melt, and
    0, the side wall 4 has a recess 6 for access to the side of the butterfly valve 1 and its drive.
    The recess 6 in the wall 4 is abutted against the stator 8 of the cylindrical floor
    5 insert 34, which may also be made of refractory material. It serves to accommodate the drive elements of the rotor 12 with a cylindrical forming surface mounted in
    0 cylindrical seat 7 of the stator 8. In this case, the rotor 12 has a through channel 13 that is perpendicular to the axis 0-0 of rotation of the rotor.
    The through channel 13 of the rotor 12 may pass not along a straight, but at an angle, so that the inlet 14 of the rotor 12 is located on its end surface, and the outlet 15 is located on its forming surface. In this case, the insert 34 has an outer flange adjacent to the outer side of the metal wall 4 of the tank, which is externally exposed to the support plate 27 in the closed position in order to fix the stator 8 in place due to the fact that it is made conical.
    The rotary shutter 1 shown in FIGS. 8 and 9 also contains a refractory rotor 12, rotated around a horizontal axis 0-0 and movable along this axis in a recess b with a cylindrical inner surface 35 of a tubular refractory stator 8, for example, having a square external cross-section. The rotor 12 fits snugly with the cylindrical surface 36 to the cylindrical inner surface 35 of the stator 8. The outlet channel 9 and the through channel 13 can also be located in the middle of the bottom. The rotary valve 1 is placed on the lining of 2 bottoms in the cavity 37 of the tank and is completely surrounded by melt during operation. It can also be partially or fully located in the lining 2 of the bottom 3. The stator 8 of the holder ends out through the side walls of the tank (Fig. 13) located on opposite sides of the tank. Thus, the rotor 12 can be driven out of rotation by means of a drive device 38. For this purpose, the rotor 12 can also protrude from the stator 8 by a desired amount. At the end of the stator, opposite the drive device 38, a locking device 39 is provided, for example, formed in the form of a flip cover.
    The stator 8 is located in the transition zone between the bottom lining 2 and the wall 3 lining (FIG. 10). Stator exhaust port 9
    8 and the through channel 13 of the rotor 12 are positioned at such an angle to each other that the melt is retracted first at an angle of slope and then vertically downwards. Exhaust channel
    9 has a conical expansion on the inlet side of the melt.
    In FIGS. 11 and 12, a dotted line indicates that the rotor 12 and the stator 8 may be composed of separate parts.
    Each part of the rotor 12 has a through channel 13, and of all the parts of the stator 8, only one has an outlet channel 9.
    The shutter works as follows.
    After the bucket cavity 37 is filled with melt and transported to the melt discharge position, the rotor 12 of the gate 1 is rotated in the stator 8 by means of the drive 24. If it is necessary to control the flow of the melt, the rotor 12 is rotated so that its drain channel 14 does not fully coincide with the drain channel 15 of the stator 8.
    To replace the rotor 12, the lock 29 is opened, the support 27 is folded down and the worn out rotor is removed, and a new one is inserted instead.
    Replacement of a rotor 12 with the stator 8 in a set is possible.
    After replacing poYopa 12 (or a rotor with a stator), the support 27 is lifted upwards and secured with a lock 29 from falling out of the rotor.
    Replacing the worn part of the rotor 12 is possible by pushing its parts along the arrow in FIG. ten.
    In this case, the worn part of the rotor is replaced even when the bucket is full and is pushed out when opening the cover 39.
    The rotor 12 is made of a soft, rapidly wearing material, such as graphite, and the stator 8 is made of hard, such as refractory concrete.
    This ensures that the surfaces 36 and 35 of the rotor 12 and the stator 8 fit snugly.
    Using the present invention will simplify the repair and maintenance of the valve, as well as increase its service life.
