GIQ-A 气动真空阀门
产品简介
详细信息
GIQ-A型气动真空蝶阀启闭件是一个圆盘形的蝶板,在阀体内绕其自身的轴线旋转,从而达到启闭或调节的阀门叫蝶阀。气动真空蝶阀全开到全关通常是小于900,高真空蝶阀和蝶杆本身没有自锁有力,为了蝶板的定位,要在阀杆上加装蜗轮减速器。采用蜗轮减速器,不仅可以使蝶板具有自锁能力,使蝶板停止在任意位置上,还能改善阀门的操作性能。工业真空蝶阀的特点能耐高温,适用压力范围也较高,阀门公称通径大,阀体采用碳钢制造,阀板的密封圈采用金属环代替橡胶环。大型高温蝶阀采用钢板焊接制造,
气动真空阀门用途:
主要用于高温介质的烟风道和煤气管道。真空蝶阀、化工、建材、电站、玻璃等行业中的通风、环保工程的含尘冷风或热风气体管道中,作为气体介质调节流量或切断装置。
气动真空阀门的优点
GIQ-A型气动真空蝶阀启闭方便迅速、省力、流体阻力小,可以经常操作。永嘉县科本真空阀门厂生产的GIQ型气动真空蝶阀结构简单,体积小,重量轻。可以运送泥浆,在管道口积存液体zui少。低压下,可以实现良好的密封。调节性能好。
0 IntroductionIt is known that every solid material can dissolve andabsorb some gases in the atmosphere.When these materialsare put into a vacuum chamber(as an environment),they willgive off the adsorbed or dissolved gases and vapors,which iscalled outgassing[1].Outgassing in the ultra-high vacuumsystem includes outgassing of ultra-high vacuum valve facility andoutgassing of testing products,and the latter of which isanalyzed in this paper.Many testing products of spacecraft,such as drivingframework
