　　进口球形止回阀产品详情Product details

　　球形式止回阀采用全水流通道，流量大，阻力小。橡胶包皮滚动球为阀瓣，在介质的作用下，可在阀体的整体式滑道上作上下滚动，从而打开或关闭阀门，密封性能好，消声式关闭，不产生水锤，广泛应用于冷水、热水、工业及生活污水管网、潜水排污泵出水口处，防止倒流及水锤对泵损害

　　The ball type check valve adopts a full water flow channel, with high flow rate and low resistance. The rubber wrapped rolling ball is a valve disc that can roll up and down on the integral slide of the valve body under the action of the medium, thereby opening or closing the valve. It has good sealing performance, soundproof closure, and does not produce water hammer. It is widely used in cold water, hot water, industrial and domestic sewage pipelines, and at the outlet of submersible sewage pumps to prevent backflow and water hammer damage to the pump
