Abstract

一种安装在常压热水采暖锅炉回水管道上的液控启闭阀,由于阀体内部摩擦运动部位装有铜套,采用锥形弹簧辅助复位,因而较长时间停用后不易锈死。锥形弹簧压缩后高度小,使液控启闭阀体积减小,可节约材料及加工费。确保管网经济安全运行。本实用新型由液控口、阀盖、阀体、定位挡圈、铜套、锥形弹簧、阀杆、活塞、阀瓣、水流进口、水流出口组成。其特征在于阀体内锥形弹簧上端与活塞连接,下端与定位挡圈连接,阀杆与铜套滑动配合。经使用效果良好,开启可靠,运行平稳。

Description

液控启闭阀
本实用新型涉及常压热水采暖锅炉回水管道上的一种液控启闭阀门。
据笔者所知,现有技术中,一般的液控启闭阀,依靠活塞下端水流的压力作用关闭阀孔。运行中往往出现关闭不严或“水击”现象,春季停炉后,冬季再使用出现阀杆锈死。从而影响该阀门的正常安全运行。
本实用新型的目的就是要提供一种阀体内阀杆摩擦部位采用铜套,设有锥形弹簧辅助复位,从而达到关闭快速、严密、并能缓释“水击”的液控启闭阀。
回水液控启闭阀由液控口、阀盖、阀体、定位挡圈、铜套、活塞、阀瓣、阀杆、锥形弹簧、水流进口、阀孔、水流出口组成,其特征在于定位挡圈和活塞之间装有锥型弹簧,阀杆与铜套滑动配合。
本实用新型的目的是这样实现的,如附图所示,当泵压水由液控口(16)输入活塞上腔(17)后,活塞(4)在液力的作用下,压缩锥型弹簧(10),通过阀杆(12)使阀瓣(11)开启,此时水流进口(14)与水流出口(15)之间导通。当水泵停止工作,液控口(16)及上腔(17)内的压力液体消失时,由于活塞(4)的面积大于阀瓣(11)的面积,管道中的回水压力作用在活塞(4)下面所产生的推力和锥形弹簧的弹力共同使活塞(4)向上运动,并通过阀杆(12)带动阀瓣(11)同步上移,最终关闭阀孔(18),从而使水流进口(14)和水流出口(15)之间截止。由于使用了锥形弹簧(10),压缩后高度小,使活塞腔高度降底,液控启闭阀体积减小,节约了材料及加工费,同时设置了铜套(13),从而避免了与阀杆(12)之间锈蚀。
下面结合附图对本实用新型作进一步说明。
附图为“液控启闭阀”的结构剖面示意图。
如图所示,阀盖(2)通过螺栓(8)与阀体(1)连接;连接处有O型密封(9),定位挡圈(7)被锁定在阀盖(2)与阀体(1)之间;活塞杆(2)上端通过螺母(5)与活塞连接;下端与阀瓣(11)连接;铜套(13)装在定位挡圈(7)内,锥形弹簧(10)装在活塞(4)与定位挡圈(7)之间。
试用表明,本实用新型“液控启闭阀”由于阀体内采用了锥形弹簧和铜套,可使液控启闭阀关闭更加灵活,严密,运行安全可靠。
