Abstract

本实用新型公开了一种带定位槽的阀杆,所述的阀杆(1)的中部设置有定位槽(2)。本实用新型阀杆中部的定位槽与卡环配合使阀杆在工作时定位准确不发生偏摆和错位。

Description

一种带定位槽的阀杆
技术领域
本实用新型涉及阀门阀杆,特别涉及带定位槽的阀杆。
背景技术
    阀杆是阀门配件之一,阀门的阀板连接在阀杆上,阀杆转动带动阀板转动实现开闭。常见的阀杆是圆柱形的,通过焊接或加工定位槽与定位环连接,工艺复杂,浪费材料。
实用新型内容
本实用新型的目的就是解决阀杆与定位环连接工艺复杂,浪费材料的问题。
本实用新型采用的技术方案是:一种带定位槽的阀杆,阀杆的中部设置有定位槽。
所述的定位槽的的横截面截面为U形。
本实用新型取得的有益效果是:阀杆中部的定位槽与卡环配合使阀杆在工作时定位准确不发生偏摆和错位。
附图说明
图1为本实用新型的结构示意图。
具体实施方式
    如图1所示,一种带定位槽的阀杆,阀杆1的中部设置有定位槽2。工作时定位槽中设置卡环工作时防止阀杆发生偏摆。定位槽2在车制加工时制作,可也铸造时直接铸出,再进行车制,这样减少了加工量。

Claims (2)

1.一种带定位槽的阀杆,其特征在于它是在阀杆(1)的中部设置有环形定位槽(2)。
2.根据权利要求1所述的带定位槽的阀杆,其特征在于所述的定位槽(2)的的横截面截面为U形。
