The device contains placed on the central (executive post) generator 1 (2) pulses, the output of which is connected to the inputs of the distributor, divided into blocks 3, 4 and 5 (6, 7 and 8) of the distributor, blocks 9 (10) of the transmission of synchronization signals, blocks 11 (12) reception of synchronization signals, blocks 13, 14 and 15 (16, 17 and 18) of control of the in-phase operation of valves, to the outputs of which windings of control relays 19, 20, 21 (22, 23, 24) are connected, to the first inputs - the output of the block 11 (12) receiving synchronization signals. The device also comprises an order transfer unit 25 (26) and an order reception unit 27 (28), blocks 28-39 (40-51) matching. The first outputs of blocks 3, 4 and 5 (6, 7 and 8) are connected to the first inputs of blocks 28-33 (40-45), the second inputs of which are connected to the output of block 27 (28) receiving orders, and the outputs to the first inputs of blocks 34-39 (46--51), the outputs connected to the signal blocks 52-57 (58-63). The second outputs of blocks 14 and 15 (16 and 17) are connected respectively to the second inputs of blocks 13 and 14 (17 and 18). The third outputs of these blocks are connected to the second inputs of blocks 52-57 (58-63), the third inputs of blocks 13, 14 and 15 (16, 17 and 18) are connected respectively to the second inputs of blocks 3, 4 and 5 (6, 7 and 8 ), the third outputs of which through the contacts 64-66 (67-69) of the control relays are connected to the input of the block 9 (10), and the fourth are connected to the input of the block 25 (27) through the series-connected contacts 70-73 (74-77) of the control relay.

The circuits of block 3 (4-8) (Fig. 3) contain O-triggers 78-81, the C inputs of which are combined and are the first inputs of block 3 (4-8), the direct output of each D-trigger is connected to D-input D of each next D-flip-flop, and the D-input of the first D-flip-flop is connected to the forward output of the 5-flip-flop 82, controlled by signals "O S-input of the flip-flop 82, connected to the output of the And 83 element, one of the inputs of which combined with the / -input of the / 5-flip-flop 82, is used to connect to the output of the last D-flip-flop of another similar block when building the distributor. Direct outputs of D-flip-flops 78-81 are also connected.

to inverters 84-87, the outputs of which are the first outputs of the block, and through resistors and optocouplers to inverters 88-91, outputs connected to the anodes of the diodes

5 92-95, the cathodes of which form the fourth outputs of block 3 (4-8). The outputs of the inverters 84-87 are connected to the inputs of the element AND 96, the output of which is connected to one of the inputs of the element AND 97 and the input of the inverter 98, the outputs of which are respectively

° the second and third outputs of the block 3 (4-8), and the second input of the element And 97 - the second input of the specified block.

The device works as follows. Under the action of pulses generated by generator 1 (2), the central (executive) station distributors switch synchronously and in phase. At the end of each cycle, the number of clock cycles in which is equal to the number of distributor positions, the third output of block 5 (8) shows the signal “1,

0, which, upon receipt of the next pulse, is recorded in the first D-flip-flop of block 3 (6). At the same time, synchronization signals are transmitted by blocks 9 (10). Synchronization signals are sensed in blocks 11.

5 (12) and arrive at the inputs of blocks 13-15 (16-18). At the same time, the third inputs receive signals from the second outputs of blocks 3, 4 and 5 (6, 7 and 8). Blocks 13–15 (16–18) compare the actual position of the distributors of the central and executive posts. In case of their mismatch or the absence of a synchronization signal, the control relays 19-21 (22-24) open the order transmission circuit with their contacts 70-73 (74-77).

During non-phase operation, the distributors, regular failures, damages of any of blocks 13-15 (16-18), the associated control relay releases measles and, with its contacts, disconnects the corresponding distributor block from the inputs of blocks 9 (10) and 25 (26). With this device

0 continues to work, but with a shorter cycle.
