Abstract

本发明提供了一种上装式深冷球阀，包括阀体、阀体内腔中设置球体，球体在阀体的轴向两侧设置有阀座，阀座上设有两个阶梯面，阶梯面Ⅰ与阀体之间安装有预紧弹簧，阶梯面Ⅱ与阀体之间安装有密封件，在阀座的轴向两侧的阀体内部安装有调节棒，调节棒的棒体设置在阀体内，其端部的六角凸台设置在阀体外，调节棒的棒体上设有凸轮曲面，所述阀座安装在轴向对称的调节棒之间，并镶嵌于楔形槽内。本发明的有益效果是利用调节棒的凸轮曲面来实现阀座的退位，结构简单，有效的解决了上装式固定球阀在线维修困难的问题。

Description

一种上装式深冷球阀
所属技术领域
本发明涉及一种球阀，特别涉及一种上装式深冷球阀。
背景技术
目前，上装式深冷固定球阀，在拆卸球体时需要克服阀座的预紧力将阀座移动，由于预紧力太大，一般方式无法实现阀座的退位，这样就给在线修理或更换带来诸多不便。
发明内容
为克服现有上装式深冷球阀的上述缺陷，本发明提供一种便于在线维修的上装式深冷球阀。
本发明解决其技术问题采用的技术方案是一种上装式深冷球阀，包括阀体、阀体内腔中设置球体，球体在阀体的轴向两侧设置有阀座，阀座上设有两个阶梯面，阶梯面Ⅰ与阀体之间安装有预紧弹簧，阶梯面Ⅱ与阀体之间安装有密封件，在阀座的轴向两侧的阀体内部安装有调节棒，调节棒的棒体设置在阀体内，其端部的六角凸台设置在阀体外，调节棒的棒体上设有凸轮曲面，所述阀座安装在轴向对称的调节棒之间，并镶嵌于凸轮曲面内。
本发明的有益效果是利用调节棒的凸轮曲面来实现阀座的退位，结构简单，有效的解决了上装式固定球阀在线维修困难的问题。
附图说明
下面结合附图和实施例对本发明进一步说明。
图1是实施例的结构示意图；
图2为图1中A-A剖视图；
图3为图1中部件8的结构示意图。
图中：1.阀体；2.球体；3.阀座；4.阶梯面Ⅰ；5.阶梯面Ⅱ；6.密封件；7.预紧弹簧；8.调节棒；9.棒体；10.六角凸台；11.凸轮曲面。
具体实施方式
如图1、2、3所示，一种上装式深冷球阀，包括阀体1、阀体内腔中设置球体2，球体2在阀体1的轴向两侧设置有阀座3，阀座3上设有两个阶梯面，阶梯面Ⅰ4与阀体1之间安装有预紧弹簧7，阶梯面Ⅱ5与阀体1之间安装有密封件6，如图2、3所示，在阀座3的轴向两侧的阀体1内部安装有调节棒8，调节棒8的棒体9设置在阀体1内，其端部的六角凸台10设置在阀体1外，调节棒8的棒体9上设有凸轮曲面11，所述阀座3安装在轴向对称的调节棒8之间，并镶嵌于凸轮曲面11内。
维修和更换球体时，只需拧动调节棒8上的六角凸台10，通过凸轮曲面11挤压阀座3，实现阀座3的退位，可以方便的进行在线维修。
