性能与用途
该阀主要用于给排水系统、石油、化工等工业部门的管道泵出口处，防止介质逆流。由于本产品的封圈采用倾斜设计，关闭时间短，可减小水锤压力。阀瓣采用于睛耐油橡胶与钢板经高温压制而成，耐冲刷，密封性能好，产品结构简单、保养、维修、运输均很方便。
Performance and use
The valve is mainly used in the outlet of the pipeline pump of the water supply and drainage system, petroleum, chemical and other industrial sectors to prevent the medium from countercurrent. Because the sealing ring of this product adopts the inclined design, the closing time is short, and the water hammer pressure can be reduced. The valve disc is made of oil resistant rubber and steel plate pressed by high temperature, which is resistant to erosion, good sealing performance, simple product structure, convenient maintenance, repair and transportation.
