Definitions

  • the present invention relates to a valve state display device.
  • the state of the valve state of the prior art is mostly specified by means of a wrench, a driving device, a user specification or various valve standards, and the state of the valve can still be accurately displayed after the wrench or the driving device is removed (in the position of the valve) Or off). Therefore, some are displayed on the top of the valve stem, but the position judgment error is large. Some of the shell marks on the valve stem and the packing gland are marked, but once the packing is replaced, the original valve position will be changed.

Description

一种阀门状态显示装置
技术领域
[0001] 本发明涉及一种阀门状态显示装置。
背景技术
[0002] 现有技术的阀门状态显示， 大都借助于扳手、 驱动装置， 用户规格书或各类阀 门标准都明确规定， 在拆除扳手或驱动装置后， 仍能精确显示阀门的状态 （在 幵位或关位） 。 于是， 有的是在阀杆顶端刻痕显示， 但位置判断误差大， 有的 在阀杆及填料压盖上壳痕加标识， 但一旦更换填料， 原阀位会被变动。
技术问题
[0003] 本发明的目的在于提供一种结构合理， 工作性能好的阀门状态显示装置。
问题的解决方案
技术解决方案
[0004] 本发明的技术解决方案是：
[0005] 一种阀门状态显示装置， 其特征是： 包括阀杆， 阀杆的头部设置与驱动装置连 接的连接结构， 阀杆的尾部銑成扁榫形式， 扁榫上套装挡圈， 且挡圈的底面与 阀杆尾部的大端面接触； 阀杆尾部大端面上加工有螺纹孔或销孔； 扁榫上设有 与挡圈卡合定位的阀杆槽；
[0006] 装配吋， 先将阀杆插入阀体及阀板， 将挡圈孔对准套入阀杆的扁榫头部， 挡圈 抵接阀杆尾部的大端面后， 旋转 90度， 挡圈就卡在阀杆槽内， 然后在螺纹孔或 销孔中装上螺钉或销钉， 螺钉或销钉与与挡圈外平面接触， 阻止挡圈的转动。
[0007] 所述连接结构为键、 方榫、 扁榫或多边形结构。
