Abstract

输液管路泄压阀,属于阀门类:是以由阀体、密封 圈、活塞、弹簧、联接管体组成的单向弹簧阀为基础; 在活塞外缘上的轴向槽中加工有径向的孔;将其并联 在输液管路中的电磁阀上,采用该泄压阀,有简便、价 格便宜、泄压迅速可靠的效果。

Description

本实用新型属于阀门类。
在输送液体的管路中,如输油管路中,一般均装有电磁阀,进行定量的计量销售。但是,在计量到量瞬时关闭电磁阀时,输液管道中的压力急逐上升,经常出现破坏管路的问题,为了克服这个问题,目前一般是在管路中装有几个电磁阀,进行分段关闭的方式;这种控制压力的方式有复杂、价格昂贵的问题。
本实用新型的目的是:提供一种简便的、价格便宜的、泄压迅速可靠的输液管路泄压阀。
本实用新型的技术措施是:以由阀体、密封圈、活塞、弹簧、联接管体组成的单向弹簧阀为基础;在活塞外缘上的轴向槽中有经向的孔。
本实用新型的泄压阀,是将现有的单向弹簧阀进行改动,在活塞外缘上的轴向槽中有经向的孔,增加泄压流速和流量,有简便、经济便宜、泄压迅速可靠的积极效果。
附图是本实用新型的结构事意图。
附图是与现有的单向弹簧阀基本相同,图中2是阀体,阀体中装密封圈1、活塞3、弹簧6、联接管体7;当压力液体达到一定压力时,将活塞3推开,液体经活塞3外缘上的轴向槽4流过。本实用新型是在这种阀的基础上加以改动,以适用瞬间减压所用。改变的部位是:在活塞3外缘上的轴向槽4中加工有径向孔5,根据管径的大小不同和瞬间减压的需要选择不同弹力的弹簧,这样就可以增加瞬间泄压流速和流量。将这种泄压阀并联在电磁阀的管路中,即可达到简便、价格便益、泄压迅速可靠的效果。
