Description

Technical Field

[0001] The utility model relates to the technical field of sealing rings, in particular to an embedded valve seat sealing ring. Background Art

[0002] The valve seat is a removable surface part in the valve, which is used to support the fully closed position of the valve core and form a sealing pair. Generally, the valve seat diameter is the maximum flow diameter of the valve. For example, the valve seat material of the butterfly valve is very wide, and various types of rubber, plastic, and metal materials can be used as valve seat materials. Among them, when installing the embedded valve seat, the seal must be carefully fixed to prevent rupture and leakage due to the pressure difference, which requires the use of a sealing ring for sealing.

[0003] After searching, the patent document (authorization announcement number is CN216618510U) discloses a valve seat sealing ring, which includes a sealing body and a supporting frame; wherein, the supporting frame is embedded in the sealing body to support the sealing body; the sealing body includes an inner ring portion, an outer ring portion and a connecting portion; the inner ring portion is located on the inner side of the outer ring portion; the inner ring portion is connected to the connecting portion, and the connecting portion is connected to the outer ring portion; a sealing abutment surface is provided at one end of the inner ring portion, and a sealing protrusion extending along the circumference of the sealing body is provided on the sealing abutment surface.

[0004] The sealing ring can effectively support the sealing body by providing the supporting frame, thereby strengthening the supporting strength of the sealing body, thereby improving the sealing performance of the sealing body, reducing the risk of leakage, and will not have the problem of flanging after long-term use, thereby extending the service life. In addition, the valve seat sealing ring is applied to a ball valve, the ball valve includes a valve core, the mounting seat is slidably connected in the mounting hole, the sealing protrusion is suitable for abutting against the valve core, and the elastic member is suitable for pressing against the mounting seat and thereby driving the sealing protrusion to press against the valve core, thereby obtaining good sealing performance.

[0005] However, the support frame is embedded in the sealing body, and the exterior of the support frame is relatively smooth. During long-term use, the support frame is easily separated from the sealing body. The support frame cannot provide good support for the sealing body during use, which makes the subsequent sealing effect worse.

[0006] To this end, we propose an embedded valve seat sealing ring to solve the problem in the prior art that the supporting frame of the sealing ring is easily separated from the sealing body during long-term use, and the supporting frame cannot provide good support for the sealing body during use, resulting in poor subsequent sealing effect.
