Abstract

PURPOSE: To keep obstacles from staying in passages at valve opeing and thus to allow slurries to flow smoothly without clogging by providing a ball valve or a cylinder valve working on automatic control at inlet port and discharge port instead of a check valve for reciprocating pump.
CONSTITUTION: Ball valves 4, 5 are connected to an inlet port and a discharge port for a reciprocating pump 1, and an automatic controller 6 is installed so as to operate the ball valves 4, 5 accordingly in accordance with forward and backward movements of a plunger 2 for the reciprocating pump 1 by a prime mover 7. For operation of the ball valves 4, 5 according to the controller 6, there is employed such a cam as is adjusted to make one revolution while the plunger 2 for the pump 1 reciprocates one time. Then, a limit switch is operated intermittently with a projection arranged at two spots opposite to the cam on its peripheral edge, and an arrangement is such that an air pressure to operate the ball valves is adjusted according to output signals of the switch, thereby opening or closing the ball valves 4, 5 alternately.
