砼泵输送分配阀是泵送过程的关键部件,其性能的优劣直接影响着砼泵对砼的吸入性能、压力损失,以及泵送砼产生堵塞的可能性。世界上泵送砼的堵塞故障多达百分之九十发生在分配阀处。平置式S型管阀(简称“S阀”)是一种应用在砼泵上的工作可靠的新型分配阀。这种阀的S管置于料斗中,其一端与出料口相接;另一端往复摆动,交替地与两个混凝土泵缸接通,从而使料斗中砼被吸入泵缸,再
The pump delivery distribution valve is a key component of the pumping process. The performance of the pump directly affects the suction performance, pressure loss, and the possibility of blockage of the pump. As many as ninety percent of the pumping defects in pumping defects in the world occur at the distribution valve. The flat S-type pipe valve (referred to as “S-valve” for short) is a new type of reliable distribution valve applied to a helium pump. The S-pipe of this valve is placed in the hopper, one end of which is connected to the discharge port; the other end oscillates back and forth, alternating with two concrete pump cylinders, so that the hopper in the hopper is sucked into the pump cylinder, and then
