A vulcanized rubber sealing structure

Abstract

This utility model discloses a vulcanized rubber sealing structure, including a metal skeleton and a rubber body. One end of the metal skeleton is tapered, and the diameter of the tapered structure gradually decreases outward along the axis. The apex angle of the axial section of the tapered structure is 1. The tapered surface of the metal skeleton is provided with an annular groove perpendicular to the center along the radial direction. The rubber body is placed in the annular groove and vulcanized with the metal skeleton. The outer surface of the rubber body is a tapered structure, and the apex angle of the axial section is 2. By controlling the angle between the vulcanized rubber and the sealing surface, the vulcanized rubber sealing structure is optimized to prevent the rubber from cracking due to pressure during sealing, resulting in high reliability.

Description

Technical Field

[0001] This utility model belongs to the field of high-pressure fluid and sealing technology, specifically relating to a vulcanized rubber sealing structure. Background Technology

[0002] Common soft sealing methods in the field of high-pressure fluid and sealing technology include sealing ring seals, non-metallic flat gasket seals, lip seals, diaphragm seals, and expanded graphite seals. The commonly used vulcanized rubber seal structure is a flat conical surface seal, which is prone to leakage due to the rubber material rupturing under pressure during sealing. This utility model is an optimization and improvement of vulcanized rubber seals. Utility Model Content

[0003] This utility model provides a vulcanized rubber sealing structure, including a metal skeleton and a rubber body. One end of the metal skeleton is tapered, and the diameter of the tapered structure gradually decreases outward along the axis. The apex angle of the axial section of the tapered structure is one. The tapered surface of the metal skeleton is provided with an annular groove perpendicular to the center along the radial direction. The rubber body is placed in the annular groove and vulcanized with the metal skeleton as one piece. The outer surface of the rubber body is a tapered structure, and the apex angle of the axial section is two.

[0004] The first vertex angle is 90°±30′, and the second vertex angle is 110°±1°.

[0011] Please see Figure 1 The figure shows a schematic diagram of the vulcanized rubber sealing structure provided by this utility model, including a metal skeleton 1 and a rubber body 2. One end of the metal skeleton 1 is tapered, and the diameter of the tapered structure gradually decreases outward along the axis. The apex angle α of the axial section of the tapered structure is 90°±30′. The tapered surface of the metal skeleton 1 is provided with an annular groove 11 perpendicularly from the radial direction to the center. The rubber body 2 is placed in the annular groove 11 and vulcanized integrally with the metal skeleton 1. The outer surface of the rubber body 2 is a tapered structure, and the apex angle β of the axial section is 110°±1°.

[0012] Figure 2 The diagram shows the vulcanized rubber sealing structure provided by this invention applied to a quick-release self-sealing joint. It consists of a connector nozzle, outer shell, sealing ring, spring, valve assembly, and nut. The connector nozzle and outer shell are connected by threads, the sealing structure uses a bore-shaft seal, and the sealing structure between the valve assembly and the outer shell uses a conical rubber seal.

[0013] The above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Any modifications or equivalent substitutions made by those skilled in the art to the technical solution of this utility model, as long as they do not depart from the spirit and scope of the technical solution of this utility model, are all covered within the scope of the claims of this utility model.
