The utility model also provides a kind of ball valve sealing structure, comprising the seal receptacle being arranged between sphere and valve body,
It is located at inlet channel and outlet flow respectively；
The seal receptacle has at least one rounded structure, which contacts with sphere, and it is close to form linear contact
Line is sealed, the side of rounded structure forms the seal receptacle conical surface.
There are two rounded structure, each rounded structure contacts the seal receptacle tool with sphere, forms two lines altogether
Property contact seal line.
The installation position of two rounded structures is interlaced, and circumference is nontangential mutually.
The radius size of the rounded structure is 2mm ~ 3mm, and the circle center distance of two rounded structures is 3 ~ 5mm.
The angular range that two seal receptacle conical surfaces are formed is 100 ° ~ 105 °.
The utility model uses convex sealing structure so that the seal form of seal receptacle and sphere is changed into line by face sealing
Sealing, reduces mutual contact area, is conducive to improve the leakproofness of ball valve.The reduction of sealing area can also reduce close
Seal the friction between seat and sphere so that switching torque is reduced, and makes ball valve lighter when being opened and closed.When ball valve is opened, can keep away
Exempt to cause sphere displacement during media impingement sphere, a downward pressure can be applied to sphere, be conducive to sphere stabilization.While two
Road sealing surface also makes the sealing performance of ball valve relatively reliable.
Description of the drawings
Fig. 1 is the structure diagram of ball valve provided by the utility model.
Fig. 2 is the partial schematic diagram of sealing structure provided by the utility model.
Specific embodiment
Below according to Fig. 1 and Fig. 2, the preferred embodiment of the utility model is illustrated.
As shown in Figure 1, the utility model provides a kind of ball valve, comprising：
Valve body 7；
The sphere 6 being arranged in valve body 7；
The seal receptacle 5 being arranged between sphere 6 and valve body 7 is located at inlet channel and outlet flow respectively.
The seal receptacle 5 is convex shape, and the protrusion part on seal receptacle 5 contacts, and seal receptacle 5 and ball with sphere 6
Body 6 forms linear contact seal line, and there are at least one linear contact seal lines between the protrusion part of seal receptacle 5 and sphere 6.
As shown in Fig. 2, the seal receptacle 5 has at least one rounded structure 3, which contacts with sphere 6,
Linear contact seal line is formed, the side of rounded structure 3 forms the seal receptacle conical surface 1.
In a preferred embodiment of the utility model, there are two rounded structure 3, each rounded structures 3 for the tool of seal receptacle 5
It is all contacted with sphere 6, forms two lines contact seal line altogether.The installation position of two rounded structures 3 is interlaced, circumference
Nontangential mutually, the radius size of rounded structure 3 is 2mm ~ 3mm, and the circle center distance of two rounded structures 3 is 3 ~ 5mm.Two close
It is 100 ° ~ 105 ° to seal the angular range that the seat conical surface 1 is formed.The angle of two conical surfaces is different, the conical surface close to sphere runner side
Taper be less than another conical surface taper, preferably, difference be 5 °.
The ball-valve structure uses convex sealing structure so that the seal form of seal receptacle and sphere is changed into line by face sealing
Sealing, reduces mutual contact area, is conducive to improve the leakproofness of ball valve.The reduction of sealing area can also reduce close
Seal the friction between seat and sphere so that switching torque is reduced, and makes ball valve lighter when being opened and closed.When ball valve is opened, can keep away
Exempt to cause sphere displacement during media impingement sphere, a downward pressure can be applied to sphere, be conducive to sphere stabilization.While two
Road sealing surface also makes the sealing performance of ball valve relatively reliable.
The utility model also provides a kind of ball valve sealing structure, comprising the seal receptacle 5 being arranged between sphere 6 and valve body 7,
