Description

Technical Field

[0001] The utility model relates to the technical field of sealing pads, in particular to a sealing pad structure. Background Art

[0002] Plate heat exchangers have the advantages of high heat transfer efficiency, low fouling coefficient, compact structure, small footprint, light weight, easy maintenance and cleaning, small terminal temperature difference, and easy change of heat exchange area and process combination. Plate heat exchangers require sealing gaskets to be set between the heat exchanger plates;

[0003] The utility model with the publication number CN216815160U discloses a plate heat exchanger sealing gasket, including a main body, a "mountain"-shaped hanging buckle arranged on the main body, an expansion snap, a positioning protrusion, and a sealing structure; the "mountain"-shaped hanging buckle is arranged inside a sealing gasket, and a plurality of expansion snaps are evenly arranged outside the main body, and the expansion snaps are used to fix the main body on the heat exchanger plate; the expansion snaps include a "one"-shaped main body, a first boss, and a second boss, the first boss and the second boss are arranged on the pressing surface of the main body, the first boss is arranged on the inner side of the pressing surface, and the second boss is arranged on the outer side of the pressing surface, and the second boss includes a concentrically arranged convex column and a convex ring, when the second boss is pressed by an external force and installed on the heat exchanger plate, the convex ring is expanded and clamped and installed on the heat exchanger plate; a plurality of positioning protrusions are evenly arranged on the inner side of the main body, and the positioning protrusions are used for positioning inside the main body, and the fixing effect of the expansion snaps is higher and the fixing method is simpler;

[0004] In the above technical solution, when the convex ring passes through the mounting hole of the plate, the convex ring is not subject to external force, expands and is stuck on the mounting hole, making the installation more stable. The expansion snaps are not only simple to install but also have a better fixing effect. When the expansion snaps are combined with the "mountain" shaped hooks to install a sealing gasket on the plate, one is installed at a fixed point and the other is fixed by a hook. Since a sealing gasket is round, it can support the installation of the entire sealing gasket, and a sealing gasket is less likely to deform. However, the sealing gasket is not corrosion-resistant and is easily damaged after long-term use, and the damaged sealing gasket affects the overall combined installation and use. The sealing gasket is not convenient for quick and stable installation or replacement. The buckle combination connection is used for a long time and the overall shaking is easily caused by external squeezing and collision, which affects the continuous combined connection.
