Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are in the premise not made the creative labor
Under every other embodiment obtained, fall within the protection scope of the utility model.
It is of the existing technology to solve the purpose of the utility model is to provide a kind of double contact ball face sealing circles of valve
Problem makes valve opening and closing process, and sphere reduces with sealing surface contact area and torque, and the setting of relief hole makes in ball valve lumen
Pressure medium reduces.
To keep the above objects, features, and advantages of the utility model more obvious and easy to understand, with reference to the accompanying drawing and have
Body embodiment is described in further detail the utility model.
It is as Figure 1-Figure 4: to present embodiments provide a kind of valve double contact ball face sealing circles, including sealing ring sheet
Body, gas pressure relief slot 9 and relief hole 10, sealing ring body are circular ring shape, and the material of sealing ring body is soft and flexible, wear-resisting
Material, preferably rubber or polytetrafluoroethylene (PTFE).
Gas pressure relief slot 9 is arranged in the outer rim of sealing ring body, and relief hole 10 is at the maximum gauge of sealing ring body, sealing
The inner edge of circle ontology includes sequentially connected primary sealing area 3, curved surface, secondary sealing area 4, inner ring surface 2 and tapered slope 6, cone
Shape inclined-plane 6 can make sealing ring body under the effect of external force, and deformation occurs, and make relief hole 10 be connected to valve input end and
Lumen.
Specifically, primary sealing area 3 and secondary sealing area 4 are the spherical surface equal with the curvature of ball body of valve, convenient for close
Seal ontology is bonded with ball body of valve, and the more traditional ball face sealing circle of Double-layer Sphere fitting area is much smaller, torsion when opening/shutting valve
Square reduces and double-layer seal, sealing effect are more preferable.
10 bottom of relief hole is provided with a groove 11, center line symmetrical setting of the groove 11 about relief hole 10, groove 11
Width be greater than relief hole 10 aperture.Wherein, groove 11 is cylindrical, prismatic, truncated cone-shaped, prismatic table shape or hemispheric
It is a kind of.
