Problems solved by technology

[0002] Well known C0 2 The temperature of the air-conditioning system can reach 140°C-150°C during normal operation, and the test temperature can reach above 180°C. Considering the extreme cold in winter in northern my country, C0 2 The air conditioning system should be able to work normally in the temperature range of -40°C to +200°C. The sealing problem is particularly prominent under this working condition. The existing sealing structure cannot guarantee the normal operation in the extreme environment mentioned above.

Abstract

The invention relates to a structure of a hard sealing gasket and belongs to the technical field of sealing of high pressure gas in operation. The sealing gasket is composed of a rubber layer and a metal layer. A combination structure of the rubber layer and the metal layer can be suitable for extremely wide temperature ranges according to the hard sealing state of a metal. On the other hand, theapplication temperature range of the rubber layer is within 50 DEG C below zero to 200 DEG C by means of volume incompressibility of rubber and excellent elasticity recovery performance of the rubberin a very wide temperature range, so that the structure has the effects of working normally and being oil-resistant and ageing-resistant.

Description

technical field [0001] The invention belongs to the technical field of sealing in high-pressure gas operation, and in particular relates to the solution of CO 2 A hard gasket structure for the sealing problem of air conditioning system pipelines. Background technique [0002] Well known C0 2 The temperature of the air-conditioning system can reach 140°C-150°C during normal operation, and the test temperature can reach above 180°C. Considering the extreme cold in winter in northern my country, C0 2 The air conditioning system should be able to work normally in the temperature range of -40°C to +200°C. The sealing problem is particularly prominent under this working condition. The existing sealing structure cannot guarantee the normal operation in the above extreme environment. Contents of the invention [0003] The present invention mainly solves the technical problems existing in the above-mentioned prior art, and provides a structure of a hard sealing gasket. [0004] ...
