Description
Technical field
This utility model relates to a kind of valve actuator, more precisely, be a kind of bidirectional hydraulic butterfly valve driving means.
Background technology
Bidirectional hydraulic butterfly valve is a kind of to use commonplace industrial equipment in commercial production, have the most wide should
Use prospect.But, the driving means charging-up lubricant oil of the bidirectional hydraulic butterfly valve commonly used at present more bothers.
Utility model content
This utility model mainly solves the technical problem existing for prior art, thus provides one once to fill use
Bidirectional hydraulic butterfly valve driving means for a long time.
Above-mentioned technical problem of the present utility model is mainly addressed by following technical proposals:
A kind of bidirectional hydraulic butterfly valve driving means, comprises a valve rod connecting portion, described valve rod connecting portion and a drive division
Being connected, be provided with a drive shaft in described drive division, described drive shaft is shaken wheel control by one, and described drive shaft controls the work of valve rod
Dynamic, described drive division is additionally provided with an elastic oil sac, described drive division and a trapped fuel chamber are connected, and described trapped fuel chamber sets
A lid, described trapped fuel chamber, drive division is had to connect with elastic oil sac inside.
As this utility model preferred embodiment, connect for tooth bar between described drive shaft and valve rod.
As this utility model preferred embodiment, described elastic oil sac is made up of nitrile rubber.
Bidirectional hydraulic butterfly valve driving means of the present utility model is provided with a trapped fuel chamber and an elasticity on drive division
Oil sac, trapped fuel chamber, drive division and elastic oil sac are internal to be connected, and after a charging-up lubricant oil, oil plant flows through entrance inside drive division
Elastic oil sac, as long as follow-up periodically extruding elastic oil sac then lubricating oil just backflow, the lubricating oil of backflow enters through drive division and deposits
Again flow into elastic oil sac after oil pocket, complete the lubrication once to mechanical part, very easy to use.
Accompanying drawing explanation
In order to be illustrated more clearly that this utility model embodiment or technical scheme of the prior art, below will be to embodiment
Or the required accompanying drawing used is briefly described in description of the prior art, it should be apparent that, the accompanying drawing in describing below is only
It is embodiments more of the present utility model, for those of ordinary skill in the art, in the premise not paying creative work
Under, it is also possible to other accompanying drawing is obtained according to these accompanying drawings.
Fig. 1 is the perspective view of bidirectional hydraulic butterfly valve driving means of the present utility model；
Fig. 2 is the perspective view of the bidirectional hydraulic butterfly valve driving means in Fig. 1, is now another visual angle.
Detailed description of the invention
Below in conjunction with the accompanying drawings preferred embodiment of the present utility model is described in detail, so that advantage of the present utility model
Can be easier to be readily appreciated by one skilled in the art with feature, thus protection domain of the present utility model is made apparent clearly
Define.
As shown in Figure 1 and Figure 2, a kind of bidirectional hydraulic butterfly valve driving means 1, comprise a valve rod connecting portion 21, described valve rod
Connecting portion 21 is connected with a drive division 22, is provided with a drive shaft 31 in described drive division 22, and described drive shaft 31 is shaken wheel by one
32 control, and described drive shaft 31 controls the activity of valve rod, are additionally provided with an elastic oil sac 4, described driving on described drive division 22
Portion 22 is connected with a trapped fuel chamber 51, and described trapped fuel chamber 51 is provided with a lid 52, described trapped fuel chamber 51, drive division 22 and bullet
Property the internal connection of oil sac 4.
Further improve as to this utility model, connect for tooth bar between described drive shaft 31 and valve rod.
Further improving as to this utility model, described elastic oil sac 4 is made up of nitrile rubber.
The bidirectional hydraulic butterfly valve driving means of this utility model is provided with a trapped fuel chamber and an elasticity on drive division
Oil sac, trapped fuel chamber, drive division and elastic oil sac are internal to be connected, and after a charging-up lubricant oil, oil plant flows through entrance inside drive division
Elastic oil sac, as long as follow-up periodically extruding elastic oil sac then lubricating oil just backflow, the lubricating oil of backflow enters through drive division and deposits
Again flow into elastic oil sac after oil pocket, complete the lubrication once to mechanical part, very easy to use.
Mentality of designing of the present utility model is below described the most in one embodiment, in the case of system allows,
This utility model can expand to the most external more functional module, thus extends its function to greatest extent.
The above, detailed description of the invention the most of the present utility model, but protection domain of the present utility model does not limit to
In this, any change expected without creative work or replacement, all should contain within protection domain of the present utility model.
Therefore, protection domain of the present utility model should be as the criterion with the protection domain that claims are limited.
