Etc. industries be widely used.
In the prior art, the seal assembly of ball valve is there are many structure, existing defects in traditional structure, seal it is insecure,
It needs often to repair.
Utility model content
In view of the above-mentioned problems, that the main purpose of the utility model is to provide a kind of sealing effects is good, firm in structure, maintenance
Convenient, the convenient end face structure of dismounting and change enhances segmented ball valve sealing structure.
The utility model is to solve above-mentioned technical problem by following technical proposals：A kind of end face structure enhancing segmentation
Formula ball valve sealing structure, end face structure enhancing segmented ball valve sealing structure include a ball sealing ring, two sealing rings,
Two sealing rings seal valve face and sealing valve insertion respectively；Ball sealing ring includes sequentially connected first face, the second face, third
Face, fourth face, the 5th face；Ball sealing ring further includes the right-angle surface for being close to valve body；Second face, fourth face, the 5th face are ball arc
Face；First face, third face are cylindrical surface；Fourth face, the 5th face are close to the sphere of ball valve.
In specific embodiment of the utility model, the ball sealing ring, two sealing rings are integrally formed knot
Structure.
In specific embodiment of the utility model, the ball sealing ring is the ball sealing ring that plastics are made into.
In specific embodiment of the utility model, two sealing rings are rubber seal.
In specific embodiment of the utility model, the section of the sealing ring of the sealing valve face is rectangle.
In specific embodiment of the utility model, the section of the sealing ring of the sealing valve insertion is circle.
The positive effect of the utility model is：End face structure enhancing segmented ball valve provided by the utility model is close
Seal structure is able to achieve ball seal, and valve chamber sealing, end face seal is of less demanding to sealing ring material, unique convex-concave structure enhancing
End face seal.High-voltage performance is good, firm in structure, and high temperature is not easy to reveal.Easy to maintenance, ball-valve structure is simple, and sealing ring is activity
Installation, dismounting and change is all more convenient, and it is simple, small in size, light-weight using the ball-valve structure of the utility model, closely may be used
It leans on.
