Embodiment Construction

[0011] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0012] Such as figure 1 As shown, a bionic sealing ring for reciprocating dynamic sealing is composed of a sealing ring body 1; the sealing ring body 1 has four contact surfaces 2, and the two ends of the contact surfaces 2 are circular contacts 3, and the contact surfaces 2 are distributed in the middle There are one or two or three circular protrusions 4, the circular protrusion 4 and the circular contact 3 are smoothly connected through the groove 5, and the multiple circular protrusions 4 can also be smoothly connected through the groove 5; The groove 5 is a V-shaped or U-shaped structure, and the bottom of the groove 5 is a circular arc transition.

[0013] Such as figure 2 As shown, installing the sealing ring body 1 in the sealing groove 6 can realize static sealing and reciprocating dynamic sealing; the material of the sealing ring b...

Abstract

The invention relates to a bionic sealing ring for reciprocating dynamic sealing. The bionic sealing ring can be used for a static sealing structure and a reciprocating dynamic sealing structure, and has excellent static sealing performance, dynamic sealing performance, wear resistance, heat resistance and fatigue resistance. According to the bionic sealing ring, the problem that sealing rings in dynamic sealing often have the problems of twisting, reversing, abrasion and fatigue failure is avoided. According to the technical scheme, a bionic sealing ring body is of a rectangular structure and has four contact surfaces, the two ends of each contact surface are circular contacts, one or two or three circular protrusions are distributed in the middle of each contact surface, the circular protrusions are in smooth connection with the circular contacts through grooves, every two adjacent circular protrusions are in smooth connection through the grooves, the grooves are of V-shaped structures or U-shaped structures, and the bottoms of the grooves are in arc transitions; and the bionic sealing ring can be made of non-metal sealing materials such as rubber and polyurethane.

Description

technical field [0001] The invention relates to the field of sealing, in particular to a bionic sealing ring for reciprocating dynamic sealing. Background technique [0002] The sealing performance of the sealing ring is directly related to the reliability and safety of the entire system structure. Common rubber sealing rings such as O-rings, rectangular rings, D-rings, X-rings, etc., are widely used in mechanical engineering, instrumentation, petrochemical, transportation engineering, aerospace, etc. due to their good self-sealing performance , nuclear industry, marine engineering and other fields. Among them, the O-ring has the widest application range, but the O-ring is prone to rolling and twisting in the reciprocating dynamic seal, especially when the friction force along the circumferential direction of the sealing ring is uneven and the coaxiality of the groove is relatively small. When it is poor, this distortion phenomenon is more obvious, which will greatly reduc...
