Description

楔形调节蝶阀阀杆
技术领域
本实用新型涉及蝶阀领域,具体属于楔形调节蝶阀阀杆。
背景技术
轨道无摩擦蝶阀在结构上改变了传统蝶阀启闭阀板的运动轨迹:开启时,碟版和阀体密封面先正面离开,然后转动碟版全开;关闭时,先转动碟版和阀体密封面对正后正向压紧。密封面在整个开关过程中完全无磨损。但是目前的阀的阀杆与压盖安装结构设计不合理,组装和工作不方便。
实用新型内容
本实用新型的目的是提供一种楔形调节蝶阀阀杆,阀杆与压杆连接设计合理,保证了阀瓣上升开启的可靠性,提高了蝶阀的整体使用性能。
本实用新型的技术方案如下:
楔形调节蝶阀阀杆,阀杆、阀座,阀座具有矩形的空腔,阀杆上具有上楔块,阀座的空腔内具有与上楔块相匹配的下楔块,下楔块滑动安装于阀座内。
    所述的阀杆具有与下楔块相匹配的楔腔。
本实用新型的阀杆可沿螺纹销上下导向移动,阀杆与压杆连接设计合理,保证了阀瓣上升开启的可靠性,提高了蝶阀的整体使用性能。
附图说明
图1为本实用新型的结构示意图。
具体实施方式
参见附图,楔形调节蝶阀阀杆,阀杆1、阀座2,阀座2具有矩形的空腔3,阀杆上具有上楔块4,阀座的空腔内具有与上楔块相匹配的下楔块5,下楔块滑动安装于阀座2内,阀杆具有与下楔块相匹配的楔腔6。

Claims (2)

1.楔形调节蝶阀阀杆,其特征在于:阀杆、阀座,阀座具有矩形的空腔,阀杆上具有上楔块,阀座的空腔内具有与上楔块相匹配的下楔块,下楔块滑动安装于阀座内。
2.根据权利要求1所述的楔形调节蝶阀阀杆,其特征在于:所述的阀杆具有与下楔块相匹配的楔腔。
