Description
Technical field
The present invention relates to a kind of valve switch instruction device and valve, especially a kind of valve switch for inside screw nonrising stem type gate valve
Instruction device and valve.
Background technique
In inside screw nonrising stem type gate valve, valve rod is only axially rotated around itself, is driven by the effect of the screw thread and valve stem nut of valve rod
Flashboard goes up and down and makes valve opening and closing.Since valve rod is not as flashboard is gone up and down, so being difficult to discover valve when operation valve
The aperture situation of door.Then, it needs that valve switch instruction device is installed for the ease of observing and operating, on inside screw nonrising stem type gate valve.
In the prior art, hidden rod sluice valve switch instruction device is usually all directly to be set on valve rod, passes through turning for valve rod
It is dynamic that gear assembly and indicate indicator is driven to show valve opening.Such as disclosed in Chinese utility model patent CN202646899U
Inside screw nonrising stem type gate valve with indicator of opening.But there are some problems in installing and using for existing indicator of opening, such as:
(1) it requires valve rod at least partially to expose except valve body when installing, otherwise can not just install；(2) corresponding on indicator of opening
The diameter of the mounting hole of valve rod and the diameter of valve rod match, and when stem diameter is there are many when specification, indicator of opening can not lead to
With.
Therefore, it needs to develop a kind of valve switch instruction device for being mounted on inside screw nonrising stem type gate valve at present, in order to pacify
Do not expose on the valve outside valve body mounted in valve rod (for example by the valve of gearbox operation), and makes this valve switch
Instruction device can be general on the valve using the valve rod of different-diameter size, enhances versatility, reduces cost.
Summary of the invention
In view of this, in order to overcome the drawbacks of the prior art, the object of the present invention is to provide one kind to be easily installed, versatility
Strong valve switch instruction device.
In order to achieve the above object, the present invention provides a kind of valve switch instruction device, including firm banking and is covered on
Lid on the firm banking, which is characterized in that further include:
Gear is driven, is rotationally worn on the fixed base by shaft, the shaft activity passes through described
Firm banking simultaneously extends downwardly；
