    The housing of a distributor valve has a first inlet for admission of a liquid which is maintained at a first pressure, a second inlet for admission of a liquid which is maintained at a higher second pressure, and at least two outlets. The cylindrical valving element has a first passage, one end of which is in permanent communication with the first inlet and the other end of which can be moved into register with a selected outlet in response to rotation of the valving element. The latter has a second passage, one end of which is in permanent communication with the second inlet and the other end of which registers with an outlet other than that which is in register with the other end of the first passage. The second passage and/or the second inlet admits highly pressurized flusing liquid into the clearances between the housing and the valving element to prevent penetration of liquid which is admitted via first inlet. The liquid which flows through the first passage contains solid particles, such as fragments of ore. The first passage resembles an elbow and extends along an arc of less than 46 degrees. The cross-sectional area of the first passage is constant and matches that of the first inlet as well as that of each outlet.

    The invention relates to hydrotransport, in particular to a valve for cyclically switching flows in the hydraulic supply of solids.
    A valve is known for cyclically switching flows during the hydraulic transport of solids in pipelines, containing a coopus with at least four branches and a rotary switching element installed inside it with deflection and flow channels, the latter of which is bent and with equal input and output openings fij,
    When the switching element is rotated, all four taps are completely locked, as a result of which the liquid columns in motion stop and after a new position of turning on the dreams, are jerked accelerated. This implies a pulsating movement. If solids with a higher specific gravity are contained in these liquid columns, they sink down and cause the mixture to separate. The consequence of this is clogging of the pipeline.
    In addition, with such a design, the injected medium changes its direction by 90 °, which. leads to higher friction within the piping system.
    The purpose of the invention is to increase the reliability of operation by ensuring an even supply of the transported material.
    The goal is achieved by the fact that in a valve for cyclically switching flows during the hydraulic transportation of solids, in pipelines, a housing with at least four taps and a rotatable switching element installed inside the Negro with deflection and flow channels, the last of which | - naked and with equal in area inlet and outlet openings, the flow channel is made curved no more than 5 ° to the feed direction the inner surface of the body and the side surface of the The key element has a cylindrical shape, while in the middle part of the housing wall an annular recess is made, forming together with
    the walls of the casing of the switching element distribution pipe connected with the inlet of the deflecting channel, the outlet of which and the outlet of the flow channel are located at one end of the switching element and in cross section. They have the form of equal semicircles with a common center.
    In addition, the outlet connected to the distribution pipeline, communicated with a pressure source of clean water.
    In this case, the cavity formed by the walls of the housing, lying above and below the annular recess, and the switching element are autonomously communicated with a pressurized source of clean water.
    FIG. 1 shows a crane, general view, in section; in fig. 2 - view A on fi g. one.
    The crane includes a housing 1 with taps 2-5. Inside the housing 1, a rotary switching element 6 is mounted, having a flow-through 7 and deflecting 8 channels. Between the walls of the annular expansion in the housing 1 and between the element 6 there is a distribution. pipe 9, connected to the outlet 5, which communicates with a pressure source of clean water. Element 6 is coupled to drive shaft 10.
    The cavity between the wall of the housing and the element 6 is communicated autonomously with the pipeline 9 through an auxiliary pipeline (not shown),
    The outlet 11 of the channel 7 and the outlet 1.2 of the channel 8 are located on one end of the element 6 and have the shape of semicircles. The inlet 13 of the channel 8 is in communication with the pipeline 9.
    The switching process is as follows.
    The inlet 14 of the flow channel 7 is permanently connected to the outlet 2, while the outlet 11 is always alternately connected to one of the outlets 3 or C, the deflecting channel 8 by its inlet 13 is permanently connected to the distribution supply water conduit 9, while outlet 12 is connected alternately with one of the taps. In the position shown, the tap 3 is connected
      ten
    with withdrawal 2 for a mixture of solids and water, and withdrawal of 4 chambers. Through the deflecting channel 8 with pure water, and the mixture of solids with water in it is given out; High pressure in the conveying pipeline.
    To reliably eliminate interference in the flow of a mixture of solids and water, the dimensions of the njadadi 1 cross section of the outlet 2, the flow channel 7, as well as the outlets 3 and i are the same and thereby provide a constant flow rate. Dead spaces, etc. there are no places with a slow flow that leads to deposits of solids.
    The semicircular holes 11 and 12 are separated from each other by a jumper 15, which is present both in the housing J and
    994
    on the taps 3 and, the jumpers are made so that when switching they do not lead to a noticeable change, i.e. Reducing the cross sections. When taking into account the shock load from solid substances in the liquid, as well as taking into account the greater pressure difference between the channels 7 "8, the bridges 15 are made of a highly durable material. A valve with more than four connections may have three holes in the shape of a third instead of two semi-circular openings.
    circle or four quarters of a circle.
    The use of the invention will make it possible to knock a blow and the resulting flow disturbances when switching flow directions, which increases reliability of operation.
