Rubber sealing gasket for plate heat exchanger

The utility model relates to a rubber sealing gasket with good sealing performance for a plate heat exchanger. The rubber sealing gasket comprises a rubber sealing gasket body, a plurality of fixing sleeves integrated with the rubber sealing gasket body are arranged on the edge of the inner side of the rubber sealing gasket body, longitudinal through holes are formed in the fixing sleeves, and thecross sections of the through holes are oval. After the rubber sealing gasket is applied, when the pressure of a medium in the plate heat exchanger rises and the rubber sealing gasket is pushed outwards, the protrusions on the plates can pull the frame of the rubber sealing gasket body through the fixing sleeves, it is guaranteed that the rubber sealing gasket is not dislocated, does not roll over and does not jump out, and the sealing quality is guaranteed. The rubber sealing gasket with the fixing sleeve solves the problem of leakage of a plate heat exchanger, and the sealing performance isimproved. 本实用新型涉及一种密封性好的板
