Description

Technical Field

[0001] The utility model relates to the technical field related to sealing elements, in particular to a novel rubber gasket structure. Background Art

[0002] Traditional plate heat exchangers use rubber sealing strips to seal between all heat exchanger plates. Semi-welded plate heat exchangers use two plates to be laser welded along the sealing groove to form a plate pair, forming a sealed channel. The special medium flows in the welding channel, and the plate pair is sealed with a sealing gasket, and is clamped between the fixed clamping plate and the movable clamping plate in a superimposed form. The semi-welded plate heat exchanger still maintains the original advantages of the plate heat exchanger, and is suitable for places with more demanding working environments, such as strong acids, strong acid mixtures, ammonia and other occasions. However, the sealing rings used for the inlet and outlet of the medium need to be paid more attention. Here, the sealing ring needs to be in contact with the special medium, and the conventional sealing strips used in actual installation must also be considered. The gasket must not only be located on the same sealing surface as the conventional sealing strips and be subjected to the same preload, but also withstand the temperature, pressure and medium performance of the heat exchange medium.

[0003] Half of the PTFE-coated rubber products used in the market simply wrap the sealing ring with a PTFE shell. The two are not combined together, or are simply bonded with glue. There is a risk of the PTFE shell detaching during use, which directly affects the sealing effect of the sealing ring.
