U41S-16P stainless steel plunger valve
Product Name:
U41S-16P stainless steel plunger valve
Description:

U41S不锈钢柱塞阀的详细资料:

产品简介:
     不锈钢柱塞阀的结构(如图所示)特点是由一个一锈钢柱塞,和下下两个富有弹性的密封环,以及能保持上下密封环固定距离的金属框架组成,柱塞尤如瓶塞一般地插入两密封环中形成圆柱形接触密封,其密封面积之大是传统截止阀无法可比的,密封效果特佳,上密封环防止外泄漏,下密封环起内密封作用,若久用之后出现渗漏时,可通过调节阀盖上固定螺栓的压力(先将阀口处于关闭状态)使密封环端面上的密封比压增加,导致经向分力增加,使之泄漏的密封环重机关报恢复密封,我厂经过多次过盈密批配合的密封试验,确定了合理的过盈密封值,经往复运动百万次,仍能完全可靠地提供良好的密封效果。
