    A group valve for selectively connecting two liquid supply lines separately to a container. The valve comprises a housing with three chambers, one of which is separately connected to the others communicating with a respective liquid line. In each chamber there is a rotary slide, said slides cooperating to at each particular time open one line and close the other. In order to prevent leakage from one line to the other said two chambers communicating with the liquid lines, respectively, are provided with an outlet to the atmosphere, said outlet of each chamber being closed by the rotary slide when the liquid line is open and open when the line is closed.

    The invention relates to rebar construction.
    Known group valve containing a housing with connecting pipes with valve chambers, interconnected by connecting channels, in each of which is placed a locking element, and all locking elements are connected to the actuator with the possibility of their synchronous rotation tiL · · / '.
    A disadvantage of the known valve is that when switching, one liquid remains in the chambers and can, during operation, contaminate another, bypassed on another line;
    Nel inventions - improving the reliability.
    This goal is achieved in that the housing contains three valve chambers, one of which is connected to two other chambers through connecting channels, in each of these two chambers there is a drainage hole that is constantly in communication with the atmosphere,. whose axis is transverse to the flow direction through the respective chambers, the locking elements are installed with the possibility of opening one wooden hole while closing another.
    In FIG. 1 schematically shows a valve in one position, in a section; in FIG. 2 - the same in a different position; 10 of FIG. 3 is an example of a hydraulic circuit for the use of Vectiles.
    The valve comprises a housing 1 with connecting pipes 2, 3 and 4 and three valve chambers 5,6 and 7, 18 of which have locking elements
    8, 9 and 10. The chamber 5 is connected to the chambers 6 and 7 by connecting channels 11 and 12, respectively. In chamber 6 and 7, drainage holes 13 and 20 14 are made, which are constantly in communication with the atmosphere, their axes being transverse to the direction of flow through the respective chambers. All locking elements are associated with a drive (not shown) of their synchronized 25 rotation and are arranged with the possibility.
    ensuring the opening of one drainage 'hole while closing another.
    As an example in FIG. 3 shows the hydraulic circuit for collecting milk. The circuit contains three reservoirs 15 for collecting milk, pipelines 16 for filling the reservoir with milk, pipelines 17 for draining milk, which are connected through shut-off valves 18 to group valves 19, 20 and 21 and then pipelines 22 to the corresponding reservoir and pipelines 23 for flushing fluid supply.
    In the case of FIG. 3, the tank on the left is filled, the middle one is flushed, and the one on the left is empty.
    This design of the valve eliminates the ingress of flushing fluid into the line with milk.

    ensuring one drainage hole is open while sheltering the other. As an example in FIG. 3 shows a hydraulic milk circuit. The scheme contains three peaepEtyapa 15 for collecting milk, pipelines 16-for filling the tank with milk, pipelines 17 for draining the milk, which are connected through shut-off valves 18 to the group valves 19, 20 and 21 and even pipelines 22 to the corresponding tank, and pipelines 23 for supplying flushing water, In the case represented by. FIG. 3, the inflatable reservoir is 1 out of 1 st, the middle one is empty and the one on the left is emptied. Such a constructive implementation of the valve eliminates the ingress of irrigating fluid into the trunk with the milk. Claims of the Invention Group valve for connecting two liquid supply lines separately to a reservoir, a recessed case i with connecting pipes and valve chambers interconnected by connecting channels, each of which has a stop element, all of which stop elements are connected with a drive ensuring their simultaneous rotation, distinguished by the fact that, in order to improve its reliability, the housing contains Tpi valve chambers, one of which is connected to two other chambers through connecting channels, in each of the two chambers, there is a drainage hole, constantly connected with the atmosphere, the axis of which {is located transverse to the flow direction through the respective chambers, the shut-off elements are installed so that one drain hole can be opened while the other is closed.
