Abstract
The utility model discloses an exempt from to maintain pneumatic ball valve contains a valve body, with be equipped with a first pipeline interface valve body integrated into one piece, with the continuous ground connection of valve body also has a second pipeline interface, still be equipped with a supporting seat on the valve body integrated into one piece, rotationally be equipped with a valve rod on the supporting seat, valve rod control flap's switching, be equipped with a box body on the supporting seat, the box body is sealed with the top surface of supporting seat, the valve rod runs through the inner chamber of box body the top surface of box body still is equipped with a plurality of emollient fillers, first pipeline interface and the surface of second pipeline interface be equipped with one deck sealing rubber, the utility model discloses an exempt from to maintain pneumatic ball valve has set up a box body on the valve body, the valve rod runs through the inside cavity of this box body, fill in the box body like this behind the lubricating oil can be in the box body long -term storage, it is regional that lubricating oil can slowly permeate the activity of the internal portion's machinery of admission valve along the valve rod, plays better lubrication action, so once filling back in the whole life need not maintain again, it is more convenient to use.
Description
Technical field
This utility model relates to a kind of valve, more precisely, be that one is exempted to maintain pneumatic ball valve.
Background technology
Ball valve is that opening and closing element (spheroid) is driven by valve rod, and the valve rotated around ball valve axis.Also can be used for regulation and the control of fluid, the most firmly seal, between V-type ball valve its V-type core and metal seat valve of pile-up welding hard alloy, there is the strongest shearing force, be particularly well-suited to the medium of fibre-bearing, small solid material etc..And multi-pass ball valve not only can control the interflow of medium, shunting and the switching flowed on pipeline flexibly, also can close arbitrary passage simultaneously and make two other passage be connected.This class valve the most typically should be horizontally mounted.Ball valve is divided into according to type of drive: pneumatic ball valve, electrical ball valve, manual ball valve.
Ball valve is in use in order to ensure that switching performance needs toward charging-up lubricant oil raising lubricity in valve lever clearance, but for some startup valves being positioned at small space, charging-up lubricant oil seems extremely difficult.
Utility model content
This utility model mainly solves the technical problem existing for prior art, thus provides a kind of once filling to use lifelong exempting to maintain pneumatic ball valve.
Above-mentioned technical problem of the present utility model is mainly addressed by following technical proposals:
One is exempted to maintain pneumatic ball valve, comprise a valve body, with described valve body molding be provided with one first pipe joint, the ground connection that is connected with described valve body also has a second pipe interface, it is provided with a support seat on described valve body the most one-body moldedly, a valve rod it is provided with rotationally on described support seat, described valve rod controls the opening and closing of valve, described support seat is provided with a box body, the end face supporting seat is sealed by described box body, described valve rod runs through the inner chamber of box body, if the end face at described box body is additionally provided with dry lubricant filler.
As this utility model preferred embodiment, described box body is made up of transparent plastic.
As this utility model preferred embodiment, described valve rod is hollow structure.
As this utility model preferred embodiment, the first described pipe joint and the surface of second pipe interface are provided with one layer of caulking gum.
As this utility model preferred embodiment, described lubricant filler is centrosymmetric distribution centered by valve rod.
Maintenance pneumatic ball valve of exempting from of the present utility model is provided with a box body on valve body, valve rod runs through the internal cavity of this box body, can preserve for a long time in box body after so filling lubricating oil in box body, lubricating oil can slowly penetrate into valve inner mechanical activity region along valve rod, play preferable lubrication, the most once need not maintain again throughout one's life after filling, more convenient to use.
Accompanying drawing explanation
In order to be illustrated more clearly that this utility model embodiment 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 embodiments more of the present utility model, 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 exempting to maintain pneumatic ball valve of the present utility model；
Fig. 2 is the perspective view that exempting from Fig. 1 maintains pneumatic ball valve, 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 and feature can be easier to be readily appreciated by one skilled in the art, thus protection domain of the present utility model is made apparent clear and definite defining.
Such as Fig. 1, shown in Fig. 2, one is exempted to maintain pneumatic ball valve 1, comprise a valve body 2, it is provided with one first pipe joint 31 one-body moldedly with described valve body 2, the ground connection that is connected with described valve body 2 also has a second pipe interface 32, it is provided with a support seat 41 on described valve body 2 the most one-body moldedly, a valve rod 42 it is provided with rotationally on described support seat 41, described valve rod 42 controls the opening and closing of valve, described support seat 41 is provided with a box body 5, the end face supporting seat 41 is sealed by described box body 5, described valve rod 42 runs through the inner chamber of box body 5, if the end face at described box body 5 is additionally provided with dry lubricant filler 6.
Further improving as to this utility model, described box body 5 is made up of transparent plastic.
Further improving as to this utility model, described valve rod 42 is hollow structure.
Further improving as to this utility model, the first described pipe joint 31 and the surface of second pipe interface 32 are provided with one layer of caulking gum.
Further improving as to this utility model, described lubricant filler 6 is centrosymmetric distribution centered by valve rod 42.
The maintenance pneumatic ball valve of exempting from of this utility model is provided with a box body on valve body, valve rod runs through the internal cavity of this box body, can preserve for a long time in box body after so filling lubricating oil in box body, lubricating oil can slowly penetrate into valve inner mechanical activity region along valve rod, play preferable lubrication, the most once need not maintain again throughout one's life after filling, more convenient to use.
Mentality of designing of the present utility model is below described the most in one embodiment, and 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 is not limited thereto, 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.
