<p>PCT No. PCT/SU80/00076 Sec. 371 Date Dec. 24, 1981 Sec. 102(e) Date Dec. 24, 1981 PCT Filed May 5, 1980 PCT Pub. No. WO81/03130 PCT Pub. Date Nov. 12, 1981.A method of controlling inlet valves of a compression reactor consists in that in the process of operation of the reactor 1 pressure in its working spaces 4, 5 and supply lines 7, 6 is continuously measured, the sign of a pressure differential ( DELTA P) between said working spaces 4, 5 and the respective supply lines 7, 6 is determined, at the instant the sign of the pressure differential ( DELTA P) changes from "minus" to "plus" a command to relieve the inlet valves 8, 9 of all control actions, except the pressure differential, is produced, and at the instant the sign of the pressure differential ( DELTA P) changes from "plus" to "minus" a command to read a preset time interval ( tau ) is supplied, at the expiration of which interval a command to close the inlet valves 8, 9 of the reactor 1 is produced. A device for controlling inlet valves of a compression reactor comprises drives 10, 11 actuating the inlet valves 8, 9 of the reactor 1, pressure pickups 14, 15, 16, 17 arranged in the working spaces 4, 5 and in the supply lines 6, 7, comparators 18, 19 connected to the outputs of the pickups 14, 15, 16, 17, units 12, 13 to control the drives 10, 11, the inputs of which are connected through time relays 20, 21 to the outputs of the comparators 18, 19 and the outputs of which are connected to the drives 10, 11, and a chronometer 22 connected with one of the comparators 18, 19.</p> |
