The one of sealing valve insertion in face in the connector loop where two sealing rings, another sealing valve face.
In specific embodiment of the utility model, the connector loop, sealing ring, ball sealing ring are integrally formed
Structure.
In specific embodiment of the utility model, the ball sealing ring includes the ball valve face for being close to the sphere of ball valve,
It is close to the obtuse angle face of connector loop, two transition faces between ball valve face and obtuse angle face.
In specific embodiment of the utility model, the angular range at obtuse angle is 92-98 degree in the obtuse angle face.
In specific embodiment of the utility model, the surface in the ball valve face is ball arcuation.
In specific embodiment of the utility model, the connector loop is metalwork.
The positive effect of the utility model is：How sealed segmentation structure provided by the utility model is enhanced
Ball valve sealing structure realizes ball seal (valve seat insert) that valve chamber sealing is (O-shaped using the connector loop of a metal respectively
Circle), end face seal (O-ring) is of less demanding to sealing ring material, and due to using metalwork in structure, intensity increases.This is practical
Novel sealing element uses versatile material, and interchangeability is good, and maintenance cost is low.The utility model is easy to maintenance, and ball-valve structure is simple,
Sealing ring is activity installation, and dismounting and change is all more convenient, simple, small in size using the ball-valve structure of the utility model, again
Amount is light, close reliable.
