Abstract

根据阀芯作直线运动的特点。本阀的大阀芯和小阀芯用金属材料制成凸圆锥形与凸球形。阀座为凹圆锥形,使阀门长期使用不内漏,该阀又克服单向流入介质的缺点,将活塞套改为全封闭式并在套上对称开孔,使介质双向对流而入,阀芯动作时不受阻,从而动作灵敏又增加了阀门的使用寿命。该阀适用于对管道中有酸碱性的介质进行自动调节和远程控制,当通电时,阀门开启,介质流通,断电后,阀门关闭,介质中断。

Description

本发明与管道介质流通控制的电磁阀有关,更具体的讲是与阀门的阀芯和活塞套有关。该装置是阀芯与阀座在启闭动作后,始终保持不内漏,阀门启闭动作灵敏可靠。
电磁阀阀芯接触面的原技术方法是用非金属材料制成为平面型来达到封闭作用,管道介质以单向流入活塞套,阀芯以平面接触,要求阀门的安装精度高,否则,就会产生内漏。用非金属制作,由于在压力的作用下,阀芯经常与阀座发生撞击而寿命短,管道介质单向流通使阀芯受到一个很大的横向力,从而使阀芯产生位移而内漏,阀芯启闭时因横向力而受阻影响阀的灵敏度及可靠性,又缩短了阀的使用寿命。
本实用新型阀,要解决的问题是阀座安装方便,不内漏,启闭灵敏可靠,延长阀的使用寿命。
本实用新型阀克服上述原有技术中的缺点,阀芯用金属材料制作增加使用寿命,小阀芯设计为凸球型(见附图1中部件3),大阀芯设计为凸圆锥型(见附图1中部件4),阀座与之补偿为凹圆锥型接合面(见附图1或附图2中部件1),这样当阀门关闭时,在压力的作用下阀芯和阀座由于是锥面而紧密配合,当压力越大密封越紧,由于阀芯为球面有万向能力,这样便于安装,本实用新型阀又将活塞套设计成封闭式,并在其套上对称开孔(见附图1或附图2中部件2),促使介质双向对流而入,克服了横向力,使阀芯不受阻而启闭灵敏可靠,又增加了使用寿命。
本发明的重要特点在于用金属材料制作的圆锥型与球型的阀芯具有万向特点而又安装方便,在压力的作用下确保不内漏,另一特点,活塞套上的对称孔使介质双向对流而入,阀芯在无横向力的情况下上下动作而使启闭灵敏可靠,由于上述优点的结合,使阀的使用寿命率增长了几倍。
