The sealing gasket of the plate heat exchanger is fixed on the plate in two ways, one is that the sealing gasket is directly adhered in the sealing groove of the plate by using an adhesive, the other is that the sealing gasket is fixed on the plate by using snap fasteners on the sealing gasket, the gasket is also called as an adhesion-free gasket, and the adhesion-free gasket is used, so that the plate heat exchanger can be more quickly overhauled and maintained, the gasket is convenient and quick to replace, and the maintenance cost is reduced.

However, the existing sealing gasket has the following problems:

1. the existing sealing gasket has poor oil resistance, corrosion resistance and wear resistance, cracks and damages are easily caused to the sealing gasket in the use process of the sealing gasket, the sealing performance of the sealing gasket is reduced, the sealing effect of a heat exchanger is poor, the heat exchange effect is not ideal, the service life is short, frequent replacement is realized, the cost is improved, and the requirements of users are difficult to meet;

2. and the rubber seal ring on the heat exchanger plate sheet on the existing market and the heat exchanger plate sheet need to use some auxiliary tools (such as glue guns) in the installation process, so that the installation process is complex, and the disassembly is relatively troublesome in the later period.
