    The invention relates to ferrous metallurgy, in particular, to devices for loading bulk materials, mainly shaft furnaces. The aim of the invention is to increase the degree of uniformity of loading by ensuring the symmetry of the material flow relative to the axis of rotation of the flaps. The metering valve consists of two turning valves in the form of a spherical segment, each of the valves is provided with a cutout symmetrical with respect to the axis of the central hole resulting from the movement of the valves. The mechanism for actuating the dampers synchronously and in opposite directions consists of levers and leads acting on the axis of the suspension and the rotation of the dampers under the action of hydraulic cylinders. In order to avoid displacement from the axis of the output stream due to the difference in the radii of curvature of the spherical segments, the whole mechanism can be completely rotated around the axis of rotation of the flaps. 9 il.

    3. There are triangular cutouts in the shutters I and 2, and a mechanism is also provided for actuating these shutters. When the flaps are turned in opposite directions, an outlet opening 4 is formed, which is close to the square in shape and symmetrical with respect to the central axis O, i.e. The distances from the horizontal a and d from the base of each cutout in the valve to the central axis O are equal to each other, regardless of the angular position of the valves,: At a symmetrical outlet, an asymmetrical flow 5 occurs, mixed from the central axis O to the distance c. The reason for this shift is the different radii of curvature of the flaps. In the example presented, the larger radius of curvature is of flap 2, which can be seen from the protrusion 6 at the seam edge of nozzle 3, therefore the curvature of flap 2 is not as large as that of flap 1. From FIG. that the output flow is shifted in the direction opposite to the flap with the greatest radius of curvature. From here, it can be concluded that a smaller radius damper creates greater braking or, conversely, a damper with a larger radius of curvature facilitates easier flow movement. To eliminate this phenomenon, the dampers are turning at an angle d relative to the O axis (see, Fig, 3 and 4) As a result, the outlet 4 (cm, g. 4) is asymmetric with respect to the central axis O, however, the output flow is symmetrical with respect to the indicated axis (see, FIG. 3), the upper flap of small radius 1 is connected to the drive shaft 7 located coaxially inside the second drive shaft 8 connected to the lower flap 2, the shafts pass through the loading nozzle 3 and can be rotated relative to each other around a common axis and relative to the nozzle 3 due to the use of sleeves or rolling-type sub-types, crossbars 9 are connected to the shafts and 10, pivotally associated with drivers 11 and 12, respectively. The opposite ends of the leads are hinged respectively to the tipping arms 13 and 14, mounted on a common axis 15 parallel to the axis of rotation of both drive shaft 7 and 8. Both the tilting arm are connected together with pin 16, as a result of which they are jointly forced rotate around axis 15. To increase strength, it is desirable to weld the arms together with each other using spacers. The tilting levers 13 and 14 are rotated by a hydraulic cylinder 17, which is mounted rotatably on an axis 18 located on the support plate 19. A pin 16 connecting the levers passes through the end of the rod 20 of the cylinder 17. Both dampers 1 and 2 and their assemblies, suspensions and drive mechanisms are installed in the socket 3 for joint rotation about the longitudinal axis of the shafts 7 and 8 relative to the socket 3. For this purpose, the outer shaft 8 is placed and installed in the cylindrical sleeve 21 and can be rotated relative to it fitting the corresponding sleeves or bearings 22, In turn, the sleeve 21 can rotate inside the bearing 23 by installing sleeves or rolling bearings 24. In addition, the sleeve 21 is connected to the base plate 19 with one or more spacers 25. At 4, 6-8, it is shown that the sleeve 21 is connected to the end of the piston rod 26 or cylinder 27, the opposite end of which is pivotally connected to the stationary bearing 23, B, hydraulic. cylinder 27 has a built-in sensor 23 of known construction that provides signals that cylinder 1 is positioned as cylinder 27, t, e, the degree of extension of the brush 26, As can be seen from FIG. 7, extending the rod 26 of the hydraulic cylinder 27 causes the o / bushing 21 to rotate around the axis rotation barrier 1 and 2 and, due to the scraping of the sleeve 21 with the supporting rod 19, causes a corresponding rotation of both shafts 7 and 8 and flaps 1 and 2 around the same axis. FIG. 9 shows a diagram of controlling the rotation of the sleeve 21 as a function of the angular opening of the shutters 1, 2. An angular position sensor 29 is connected to the shaft 7, which continuously provides a signal about the angular position p of the shutter 1 relative to the specific reference position, for example, closed. The obtained information is transmitted to the memory 30, where data on the installation of the optimal angular position with the / sleeve 2 1 is stored as a function of the angular position of the opening of the shutter 1 for different flow rates and different types of materials. All these data are obtained from preliminary tests and are related to the dpina of the extensions of the rod 26 of the hydraulic cylinder 27. Thus, the storage device 30 provides the set value x amplitude of the rod 26 as a function of the angular positions ft measured by the sensor 29. Information is fed to the comparator 31. The comparator also comes from a sensor 28 embedded in the hydraulic cylinder 27, which is informative about the actual amplitude and extension of the rod 26. The comparator 31 controls the hydraulic valve 32, which regulates The flow rate and the direction of circulation of the hydraulic medium between the pump 33 and the cylinder 27. The comparator 31 shows the difference x between the set position X and the actual position x, then the hydraulic valve 32 is commanded to create a circulation of the hydraulic medium in the appropriate direction for decrease the difference of 4x so that the actual position x corresponds to the given position X. For example, if the angular position with / is too small, then minus x. In this case, the valve 32 directs the hydraulic fluid into the cylinder to exit the rod 26 and increase the amplitude x until it is equal to the predetermined value x. The device presented on 4ng. 9, can work in two different modes. Thus, with the aid of a cylinder 27, the sleeve 21 can be rotated with the shutters 1, 2 closed to a predetermined position stored in the memory 30 without taking into account the function of the opening angle d. Upon reaching the predetermined angular position 0, the action of the hydraulic cylinder 27 is stopped and the hydraulic cylinder 17 enters into effect for the simultaneous movement of both flaps in opposite directions. In the second mode of operation, the hydraulic cylinder 17 is activated from the very beginning to simultaneously open the flaps 1 and 2. The hydraulic cylinder 27 operates gradually and as a function of the opening angle a / 5 of the flaps 1 and 2, depending on the value set in the storage device 30. When approaching the position of the maximum opening of the valve 2, which is shown at 4 mg. 3, it is possible to fully actuate the hydraulic cylinder 27 in the opposite direction in order to completely open the flap 1 so as to avoid the stop of the flap 2 in the nozzle 3. One of the advantages of the proposed mechanism is its adaptability to the properties of the different chargeable materials. In addition, it is possible for the operator to intervene in the centering of the outlet stream during the operation of the blast furnace, i.e. The operator can determine the degree of uniformity of the charged charge and the intervention at the level of the metering valve using appropriate measuring instruments.
