Abstract
The utility model relates to a ball valve structure, including the valve body the valve body on be equipped with water inlet and delivery port the inside fill water cavity that is equipped with of valve body communicate with water inlet and delivery port, fill water cavity in be equipped with the valve ball, the valve ball on be equipped with logical water course valve ball top be equipped with the valve rod the valve rod on be equipped with rotatory handle, valve ball and valve body between be equipped with the sealing member, the sealing member be inside hollow rubber layer rubber in situ chamber be full of compressed air. After having adopted above -mentioned structure, through letting in compressed air at the rubber in situ, after wearing and tearing take place for the rubber layer, compressed air make the rubber layer still with valve ball in close contact with, reach sealed effect, increased the life of product, simple structure, the convenient manufacturing.
Description
Technical field
The utility model relates to a kind of valve mechanism in mechanical design field, especially relates to a kind of ball-valve structure of favorable sealing property.
Background technique
Ball valve is widely used in various pipes, and ball valve is mainly used to do in pipeline
cut off, distribute and change
mediumflow direction, it is tight that it only needs to use the operation of 90-degree rotation and very little moment of rotation just can close, ball valve forms primarily of valve body, valve ball, valve rod and handle, metal is adopted to reach sealing effect with hard contact of metal, but the easy stuck foreign matter of this sealing means valve ball, long-time use can cause ball surface to produce mechanical wear, and occurs that leakage phenomenon occurs, and adopt the sealing means adding sealing layer also to there will be wearing and tearing, reduce the working life of ball valve.
Summary of the invention
Technical problem to be solved in the utility model is to provide and a kind ofly can completes sealing effect and the ball-valve structure increased the service life.
The technical scheme in the invention for solving the technical problem is: a kind of ball-valve structure, comprise valve body, described valve body is provided with water intake and water outlet, be provided with water flowing chamber at described valve inner to be communicated with water outlet with water intake, valve ball is provided with in described water flowing chamber, described valve ball is provided with waterway, valve rod is provided with above described valve ball, described valve rod is provided with rotating handles, Sealing is provided with between described valve ball and valve body, described Sealing is the rubber layer of inner hollow, pressurized air is full of at described rubber layer inner chamber.
Concrete further, described rubber layer is provided with suction port.
Concrete further, described Sealing is fixed on valve body.
Concrete further, the internal layer of described rubber layer is divided into some Seal cages spaced apart from each other.
The beneficial effects of the utility model are: after have employed said structure, by passing into pressurized air in rubber layer, after rubber layer weares and teares, pressurized air make rubber layer still with valve ball close contact, reach sealing effect, add the working life of product, structure is simple, convenient manufacture.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the structural representation of the utility model Sealing.
In figure: 1, valve body; 2, valve rod; 3, rotating handles; 4, water intake; 5, water outlet; 6, valve ball; 7, water flowing chamber; 8, waterway; 9, Sealing; 91, rubber layer; 92, pressurized air.
Embodiment
Below in conjunction with accompanying drawing, the utility model is explained in detail.
A kind of ball-valve structure as depicted in figs. 1 and 2, comprise valve body 1, described valve body 1 is provided with water intake 4 and water outlet 5, be provided with water flowing chamber 7 in described valve body 1 inside to be communicated with water outlet 5 with water intake 4, valve ball 6 is provided with in described water flowing chamber 7, described valve ball 6 is provided with waterway 8, valve rod 2 is provided with above described valve ball 6, described valve rod 2 is provided with rotating handles 3, Sealing 9 is provided with between described valve ball 6 and valve body 1, described Sealing 9 is the rubber layer 91 of inner hollow, is full of pressurized air 92 at described rubber layer 91 inner chamber; Described rubber layer 91 is provided with suction port; Described Sealing 9 is fixed on valve body 1.
When using, by suction port, rubber layer 91 is inflated, be full of, after rubber layer 91 weares and teares, gas makes rubber layer 91 still contact with valve ball 6, and sealing effect is good, working life extends, and can bear and repeatedly wear and tear, and can also continue to use after wearing and tearing.
Further, the internal layer of described rubber layer 91 is divided into some Seal cages spaced apart from each other, when one of them Seal cage wearing and tearing break after other can also continue use, can not sealing effect be affected.
It is emphasized that: be only preferred embodiment of the present utility model above, not any pro forma restriction is done to the utility model, every above embodiment is done according to technical spirit of the present utility model any simple modification, equivalent variations and modification, all still belong in the scope of technical solutions of the utility model.
