Embodiment Construction

[0013] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0014] Such as figure 1 As shown, a compensating sealing ring includes a ring body 1, and the inner ring surface of the ring body 1 is provided with a gap 2 extending in the circumferential direction. The distance is greater than the distance inside the slit, and a sealing strip 3 corresponding to the shape of the slit is provided in the slit 2 . The inner ring surface of the sealing strip is located outside the gap, and the inner ring surface of the sealing strip is 1mm away from the inner ring surface of the ring. The cross section of the gap is triangular.

[0015] Although the specific implementation of the present invention has been described above in conjunction with the accompanying drawings, it does not limit the protection scope of the present invention. On the basis of the technical solution of the present invention, those skilled in the art...

Abstract

The invention discloses a compensation type sealing ring which comprises a ring body, wherein a clearance extending along the circumferential direction is arranged an annular surface of the ring body; bevel edges are arranged on two sides of the clearance section; the distances of the bevel edges at a clearance opening are greater than the distances of the bevel edges inside the clearance; and a sealing strip corresponding to the clearance in shape is arranged in the clearance. According to the sealing ring with the structure, the sealing ring is extruded by two sides during mounting and a force of the ring body towards an inner axial direction is converted into a thrust for the sealing strip in the axial direction and further a better sealing action is achieved.

Description

[0001] technical field [0002] The invention relates to a sealing ring, in particular to a compensation type sealing ring. Background technique [0003] The O-ring is a ring-shaped sealing ring. Because of its simple structure and easy installation, it is widely used in the sealing connection of various equipment. After repeated use, the O-ring is easily crushed and loses its elasticity, and the sealing performance of the joint is reduced. At present, there are many compensation type sealing rings, although they have a good sealing effect, but their structures are relatively complicated and the production cost is high. Contents of the invention [0004] In order to solve the deficiencies in the prior art, the invention provides a compensating sealing ring. [0005] To achieve the above object, the present invention adopts the following technical solutions: [0006] A compensating sealing ring, comprising a ring body, the annular surface of the ring body is provided wit...
