Abstract

压差活塞阀属于阀门类,在阀体的控制孔中装有 一个凹形活塞;阀盖底面有一个凸通孔,通孔上端是 螺孔,通孔的中下部的外壁上套有弹簧;该阀依靠油 泵微弱的压力即可开启,有无水击,计量精度高、造价 低、安全性好的特点。

Description

本实用新型属于阀门类。
在油库中,采用泵付油工艺流程中,为了自动计量付油,在泵的后面的管路中需加置一个控制阀门,以控制付油量的多少;目前在管路中所加置的有电动阀、电磁阀;存在的问题是:有水击现象,计量精度不够、造价高、电动阀门在燃料油的条件下工作安全性也较差。
本实用新型的目的是:提供一种无水击现象的、计量精度高的、造价低的、安全性好 的压差塞活阀。
本实用新型的技术措施是:采用一个阀体,阀体控制孔中装有一个凹形活塞;阀盖底面有一个凸通孔,通孔上端是螺孔,通孔的中下部的外壁上套有弹簧。
附图是本实用新型的结构示意图。
图中7是阀体,阀体的进出孔端采用法兰盘与管路相联接,在阀体7的控制孔中装有一个凹形活塞6,阀盖1通过螺栓3与阀体7相联接,由密封圈4进行密封;在阀盖1底面有一个凸通孔,通孔上端是螺孔,通孔的中下部的外壁上套有一个弹簧5;为了调节弹簧对活塞6的压力,在阀盖凸通孔外壁上套有一个调节垫2。为了维修活塞6取出的方便,在凹形活塞6的底部有一个盲螺孔。为了排污在阀体7的底部有一个排污螺孔及螺钉8。
