一种加油机用截止阀
本专利技术涉及泵阀机械
,具体为一种加油机用截止阀。
技术介绍
截止阀属于强制密封式阀门,所以在阀门关闭时,必须向阀瓣施加压力,以强制密封面不泄漏,当介质由阀瓣下方进入阀门时,操作力所需要克服的阻力,是阀杆和填料的摩擦力与由介质的压力所产生的推力,关阀门的力比开阀门的力大,所以阀杆的直径要大,否则会发生阀杆顶弯的故障,按连接方式分为三种:法兰连接、丝扣连接、焊接连接,从自密封的阀门出现后,截止阀的介质流向就改由阀瓣上方进入阀腔,这时在介质压力作用下,关阀门的力小,而开阀门的力大,阀杆的直径可以相应地减少,同时,在介质作用下,这种形式的阀门也较严密。1.现有的加油机用截止阀在使用工程中转丝阀杆带动阀瓣向下移动,从而将阀门关闭,但是阀瓣会随着转丝阀杆转动,这样阀瓣就会有阀门内壁产生摩擦,这样就会造成阀瓣磨损,导致阀门截止不严密。2.现有的加油机用截止阀使用时,阀瓣与连接口之间的密封性能较低,容易出现泄漏情况,开启不是很方便,而且当阀瓣因流体介质的侵蚀而发生磨损时,就会导致阀瓣无法将流通口进行封堵,导致漏液的发生,这就需要工人频繁更换新的阀瓣, ...
