Detailed Description
It should be noted that the embodiments and features of the embodiments of the present invention may be combined with each other without conflict.
The following detailed description of the embodiments of the invention is provided.
A high-sealing ball valve seal is disclosed, as shown in figures 1 to 3, and comprises a main body with a V-shaped cross section, wherein an opening of the main body is along the axial direction, an inner sealing body 1 is formed at the inner side of the radial direction of the sealing body, and an outer sealing body 2 is formed at the outer side of the radial direction of the sealing body; the outer sealing body protrudes out of the inner sealing body towards one side of the opening of the main body along the axial direction;
an inner radial sealing surface 3 is arranged on the inner sealing body; an outer radial sealing surface 4 is arranged on the outer sealing body, and an outer axial sealing surface 5 is arranged on the outer wall surface of the outer sealing body;
a buffer ring cavity 6 is arranged in the inner sealing body, a main sealing surface 7 is arranged on one side of the inner sealing body, which is different from the opening of the main body, and an inner sealing convex ring 8 with an arc-shaped outer edge is arranged on the main sealing surface. The inner sealing convex ring is an annular bulge surrounding the main body (inner wall), and at least two inner sealing convex rings are generally arranged to ensure better and reliable sealing.
The buffering ring cavity surrounds the sealing body in the circumferential direction for a circle, and the cross section of the buffering ring cavity is circular or elliptical. The buffering ring cavity is provided with at least one, and can be when forming sealedly, produce deformation under the case pressure effort (and the pressure that main part open-ended internal pressure change produced), the buffering ring cavity provides the space of deformation, forms more stable encapsulated situation.
In an alternative embodiment, as shown in figures 2 and 3, a reinforcing strut 9 is provided inside the body, which extends through the inner and outer sealing bodies. Usually, the reinforcing support is made of spring steel or carbon fiber, and the outer sealing body can be vulcanized. Strengthen support piece and have elasticity and the resilience of deformation, can provide deformation recovery effort for the main part when the case is opened and closed at every turn, strengthen support piece and provide reaction force when the case is closed for the laminating of main seal face and case forms stable sealed. After the valve core is opened, the sealing main body structure can be restored to the original state, so that when the valve core is closed again, good sealing is formed.
