Gate has two sealing surfaces, the most commonly used wedge gate valve sealing surface to form two wedge-shaped, wedge Angle parameters vary with the valve.
闸板有两个密封面,最常用的楔式闸板阀的两个密封面形成楔形,楔形角随阀门参数而异。
And because the wedge block and the role of the dovetail groove of the stem, the valve increases the forced sealing force, increases the sealing pressure ratio, the two-way sealing.
而且由于阀杆的楔形块与燕尾槽的作用,对阀门增加了强制密封力,增大了密封比压,实现双向密封。
The bottom of the disc is made of knife-shaped gate with a cut off function of the medium. When gate is closed, oblique plane of gate valve encounters wedge block of gate to achieve sealing effect.
闸板底部做成刀形斜面具有切断介质功能,而且闸板关闭时通过阀体上的锲块紧靠闸板斜切面使得闸板紧紧贴靠阀座密封面,从而起到了密封效果。
