复合密封式平板闸阀

The multiple and sealed plain valve

复合密封式平板闸阀具有开启力小 ,密封可靠 ,使用寿命长等优点。该阀阀座的摩擦系数为 0 0 2～ 0 0 4,而且耐磨性好。复合密封式结构保证了阀座不因闸板往复运动产生的磨损 。

The multiple and sealed plain valve has many merits,such as least openning power,longer using age.and the collision factor of the valve's seat is 0.02 to 0.04,also better grind vesist.The organization has assured that the valve's seat would not damaged because of the continue motion of valve,and reduce messure of pressing and dowturn the effect of pressurizing.
