Abstract
The invention discloses a driving device for a two-way hydraulic butterfly valve. The driving device comprises a valve rod connecting part, wherein the valve rod connecting part is connected with a driving part; a driving shaft is arranged inside the driving part; the driving shaft is controlled by a rocking wheel; the driving shaft controls the motion of a valve rod; an elastic oil sac is further arranged on the driving part; the driving part communicates with an oil storage cavity; a cover body is arranged on the oil storage cavity; interiors of the oil storage cavity, the driving part and the elastic oil sac communicate with each other; the driving shaft and the valve rod are in rack connection; and the elastic oil sac is made of nitrile rubber. According to the driving device for the two-way hydraulic butterfly valve, the oil storage cavity and the elastic oil sac are arranged on the driving part, the interiors of the oil storage cavity, the driving part and the elastic oil sac communicate with each other, after lubricating oil is added at a time, the oil material flows through the interior of the driving part to enter the elastic oil sac, in the follow-up process, the lubricating oil backflows only through regularly squeezing the elastic oil sac, after entering the oil storage cavity through the driving part, the backflow lubricating oil enters the elastic oil sac again, mechanical parts are lubricated at a time, and the utilization is quite convenient.
Description
Technical field
The present invention 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, has the most wide application prospect.But, the driving means charging-up lubricant oil of the bidirectional hydraulic butterfly valve commonly used at present more bothers.
Summary of the invention
The present invention mainly solves the technical problem existing for prior art, thus provides a kind of once filling to use bidirectional hydraulic butterfly valve driving means for a long time.
The above-mentioned technical problem of the present invention is mainly addressed by following technical proposals:
A kind of bidirectional hydraulic butterfly valve driving means, comprise a valve rod connecting portion, described valve rod connecting portion and a drive division are connected, being provided with a drive shaft in described drive division, described drive shaft is shaken wheel control by one, and described drive shaft controls the activity of valve rod, 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 is provided with a lid, and described trapped fuel chamber, drive division connect with elastic oil sac inside.
As preferred embodiment of the present invention, connect for tooth bar between described drive shaft and valve rod.
As preferred embodiment of the present invention, described elastic oil sac is made up of nitrile rubber.
The bidirectional hydraulic butterfly valve driving means of the present invention is provided with a trapped fuel chamber and an elastic oil sac on drive division, trapped fuel chamber, drive division connect with elastic oil sac inside, after charging-up lubricant oil, oil plant flows through the elastic oil sac of entrance inside drive division, if follow-up periodically extruding elastic oil sac then lubricating oil just backflow, the lubricating oil of backflow again flows into elastic oil sac after drive division enters trapped fuel chamber, complete the lubrication once to mechanical part, very easy to use.
Accompanying drawing explanation
In order to be illustrated more clearly that the embodiment of the present invention or technical scheme of the prior art, the accompanying drawing used required in embodiment or description of the prior art will be briefly described below, apparently, accompanying drawing in describing below is only some embodiments of the present invention, for those of ordinary skill in the art, on the premise of not paying creative work, it is also possible to obtain other accompanying drawing according to these accompanying drawings.
Fig. 1 is the perspective view of the bidirectional hydraulic butterfly valve driving means of the present invention；
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 the preferred embodiments of the present invention are described in detail, so that advantages and features of the invention can be easier to be readily appreciated by one skilled in the art, thus protection scope of the present invention are made apparent clear and definite defining.
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, a drive shaft 31 it is provided with in described drive division 22, described drive shaft 31 is shaken wheel 32 control by one, described drive shaft 31 controls the activity of valve rod, described drive division 22 is additionally provided with an elastic oil sac 4, described drive division 22 is connected with a trapped fuel chamber 51, described trapped fuel chamber 51 is provided with a lid 52, and described trapped fuel chamber 51, drive division 22 connect with elastic oil sac 4 inside.
As to further improvement of the present invention, connect for tooth bar between described drive shaft 31 and valve rod.
As to further improvement of the present invention, described elastic oil sac 4 is made up of nitrile rubber.
The bidirectional hydraulic butterfly valve driving means of this invention is provided with a trapped fuel chamber and an elastic oil sac on drive division, trapped fuel chamber, drive division connect with elastic oil sac inside, after charging-up lubricant oil, oil plant flows through the elastic oil sac of entrance inside drive division, if follow-up periodically extruding elastic oil sac then lubricating oil just backflow, the lubricating oil of backflow again flows into elastic oil sac after drive division enters trapped fuel chamber, complete the lubrication once to mechanical part, very easy to use.
The mentality of designing of the present invention is below described the most in one embodiment, and in the case of system allows, the present invention can expand to the most external more functional module, thus extends its function to greatest extent.
The above, the only detailed description of the invention of the present invention, but protection scope of the present invention is not limited thereto, any change expected without creative work or replacement, all should contain within protection scope of the present invention.Therefore, protection scope of the present invention should be as the criterion with the protection domain that claims are limited.
