Description

顶装式球阀
技术领域
 本实用新型专利涉及流体控制技术领域,特别是一种顶装式球阀。
背景技术
顶装式球阀因其具有在线维修功能而深受用户喜爱,其设计制作难点在退阀座机构,目前的顶装式球阀基本采用楔块机构退阀座,该机构比较复杂,加工精度要求高,同时在使用中可能会出现因楔块脱落现象而无法退阀座,不能在线维修。
发明内容
本实用新型旨在解决现有项装式球阀存在退阀座机构复杂、难于实现在线维修等技术问题,以提供一种具有简单可靠的退阀座机构、可真正实现阀门在线维修功能的顶装式球阀。
本实用新型的目的是通过以下技术方案实现的。
本实用新型的顶装式球阀,包括带外螺纹弹簧座4套设于阀座3的外周;弹簧座螺母5套设于带外螺纹弹簧座4的外周,两者通过螺纹相连接;带外螺纹弹簧座4靠近球体2的端面上沿圆周方向均布有数个水平盲孔,盲孔内装置弹簧,弹簧的一端与阀座3相接。
本实用新型的顶装式球阀,其中所述的阀体1上设有防退机构,其位于弹簧座螺母5朝向阀杆6的一侧,防退机构由销9和套接在销9上的O形圈10组成,销9的中心线与阀体1的水平中心线相交,弹簧座螺母5的外周距离阀体1水平中心线的长度大于销9的端部距离阀体1水平中心线的长度。
本实用新型顶装式球阀的有益效果:
1.提高阀门退阀座机构的可靠性;
2.完全实现了在线维修功能;
3.有效降低制造成本。

具体实施方式
本实用新型详细结构、应用原理、作用与功效,参照附图1-3,通过如下实施方式予以说明。
如附图1-3,本实用新型的顶装式球阀,包括带外螺纹弹簧座4套设于阀座3的外周;弹簧座螺母5套设于带外螺纹弹簧座4的外周,两者通过螺纹相连接;带外螺纹弹簧座4靠近球体2的端面上沿圆周方向均布有数个水平盲孔,盲孔内装置弹簧,弹簧的一端与阀座3相接。阀体1上设有防退机构,其位于弹簧座螺母5朝向阀杆6的一侧,防退机构由销9和套接在销9上的O形圈10组成,销9的中心线与阀体1的水平中心线相交,弹簧座螺母5的外周距离阀体1水平中心线的长度大于销9的端部距离阀体1水平中心线的长度。
本实用新型的顶装式球阀,包括阀体、安在阀体中的球体、阀座、带外螺纹弹簧座、弹簧座螺母、防退机构以及球体、与球体连接的阀杆,采用螺纹阀座结构,依靠旋转弹簧座螺母5来带动带外螺纹弹簧座4,带外螺纹弹簧座4带动阀座3向球体2方向移动实现密封,向球体2反向移动退出阀座3拿出球体2实现在线维修,同时在弹簧座螺母5前端设有防退机构,防止弹簧座螺母5在旋转时直接退出,阀座和弹簧座不动。采用以上结构后,有效的降低了制造成本,提高了阀门退阀座机构的可靠性能,完全实现了在线维修功能。
