Description

Technical Field

[0001] The utility model relates to the field of gaskets, in particular to a high-strength metal-clad ceramic gasket. Background Art

[0002] In industrial production, gaskets are used as sealing elements between connectors, and their performance directly affects the sealing effect and operating stability of the equipment. Traditional gasket materials, such as metal gaskets or rubber gaskets, have certain advantages, but also have obvious limitations. For example, metal gaskets have high strength and high temperature resistance, but relatively poor sealing performance; while rubber gaskets have good sealing performance, but limited high temperature resistance and pressure bearing capacity.

[0003] In order to meet the requirements for higher performance of gaskets, people began to try to combine metal with high-performance materials such as ceramics to form composite gaskets. Among them, metal-coated ceramic gaskets combine the advantages of high strength of metal and high hardness and high wear resistance of ceramics, becoming an ideal gasket material. However, existing metal-coated ceramic gaskets still have some structural deficiencies, such as unsatisfactory sealing performance and inconvenient installation. Utility Model Content

[0004] The utility model aims to provide a high-strength metal-clad ceramic gasket to solve the problems raised in the above-mentioned background technology.

[0005] To achieve the above purpose, the utility model provides the following technical solution: a high-strength metal-coated ceramic gasket, comprising a ceramic substrate, the outer side of the ceramic substrate is sleeved with a high-strength stainless steel ring, and the outer side of the high-strength stainless steel ring is wrapped with a rubber cover.

[0006] Preferably, the ceramic substrate is in a circular plate structure, and the high-strength stainless steel sleeve ring has a cross section of "C"

[0007] The circular ring plate structure is in the shape of a letter "U", and an annular gap is reserved between the two end plates of the high-strength stainless steel ring and the ceramic substrate for installing the sealing plate.

[0008] Preferably, the sealing plate includes a high-strength stainless steel sealing plate, which has a circular plate-like structure. The high-strength stainless steel sealing plate is clamped in the annular gap between the two end plates of the high-strength stainless steel ring and the ceramic substrate, and the distance between the inner annular surface of the high-strength stainless steel sealing plate and the outer annular surface of the high-strength stainless steel sealing plate is greater than the distance between the two end plates of the high-strength stainless steel ring.

[0009] Preferably, a pressing groove is integrally formed on the outer ring surface of the high-strength stainless steel sleeve, and the pressing groove is a "匚"-shaped annular groove, and one end of the pressing groove extends to the bottom surface of the high-strength stainless steel sleeve.

[0010] Preferably, the rubber cover is sleeved in the pressing groove.

[0011] Preferably, the rubber cover includes a rubber plug ring. The rubber plug ring has a circular plate-like structure. The rubber plug ring is inserted into the groove between the two end plates of the high-strength stainless steel sleeve ring. An integrally formed rubber connecting ring is provided on the outer ring surface of the rubber plug ring. The rubber connecting ring has a circular plate-like structure. The outer diameter of the rubber connecting ring is equal to the outer diameter of the high-strength stainless steel sleeve ring. An integrally formed rubber sleeve ring is provided on the outer ring surface of the rubber connecting ring. The rubber sleeve ring has a circular ring plate structure with a cross-section in the shape of "L". The rubber sleeve ring is sleeved in the grooves on the outer ring surface and the bottom surface of the high-strength stainless steel sleeve ring where the pressing groove is located.

[0012] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0013] For the high-strength metal-coated ceramic gasket proposed by the present utility model, by wrapping a rubber cover outside the high-strength stainless steel sleeve ring, the sealing performance of the gasket is effectively enhanced. The rubber plug ring part of the rubber cover is inserted between the two bent side plate notches of the high-strength stainless steel sleeve ring, and the rubber sleeve ring part is sleeved in the pressing groove on the bottom surface of the high-strength stainless steel sleeve ring, forming a tight sealing structure. This design not only improves the sealing performance of the gasket after installation but also effectively prevents medium leakage. The cooperation between the "C"-shaped structure of the high-strength stainless steel sleeve ring and the high-strength stainless steel sealing plate enables the gasket to maintain a stable structure under pressure and is not easily deformed. At the same time, the rubber connecting ring part of the rubber cover, as the connecting part between the rubber plug ring and the rubber sleeve ring, also enhances the structural stability of the entire gasket.
