GASKET FOR A PLATE-TYPE GASKETED HEAT EXCHANGER

Abstract

A gasket for a plate-type gasketed heat exchanger has on its surface at least one protrusion (1A) and at least one catch (1B), which enable the assembly of the gasket (1) to the heating plate (2) along the axis of heating plate manufacturing/pressing, with a press-in method, wherein each protrusion 1A is pressed into the corresponding cutout 2A in the heating plate, and perpendicular to the axis of heating plate manufacturing/pressing, with a catch-on method, wherein each catch 1B catches on the corresponding fragment of the profiled edge 2B of the heating plate.

Claims

1. A gasket for a plate-type gasketed heat exchanger, wherein the gasket comprises on its surface at least: one protrusion (1A) and at least one catch (1B), which enable the assembly of the gasket (1) to the heating plate (2) along the axis of heating plate manufacturing/pressing, with a press-in method, wherein each protrusion 1A is pressed into the corresponding cutout 2A in the heating plate, and perpendicular to the axis of heating plate manufacturing/pressing, with a catch-on method, wherein each catch 1B catches on the corresponding fragment of the profiled edge 2B of the heating plate.

DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS

[0015] The hybrid gasket is made of NBR material with a maximum operating temperature 110° C., its overall width is 155 mm, and the overall length is 350 mm. The gasket has on its surface 4 protrusions (1A) and 3 catches (1B) that allow hybrid (using press-in protrusions and catch-on catches) installation of the gasket in the heating plate (2) of a plate-type gasketed heat exchanger. The heating plate (2) has 4 cutouts (2A) for protrusions (1A) and 3 fragments of the profiled edge (2B) for catches (1B). The protrusions (1A) and the catches (1B) are located longitudinally the sides of the heating plate (2) of the gasketed heat exchanger and/or along port holes (6) in the heating plate (2) of the gasketed plate heat exchanger at a distance of not less than 15 mm from each other. Mounting the gasket (1) to the heating plate (2) is non-invasive, impermanent. Plate heat exchanger (FIG. 5) has heating plates (2) with port holes (6) and gaskets (1) forming a heating plate package (3), which is mounted on the leading beam of the heat exchanger frame (7) and screwed with screws (5) and cover plates (4). Components of heat exchanger, in particular heating plates (2), are made of stainless steel, but they can also be made of titanium, its alloys or various metals and/or alloys of metals and/or non-metals and/or plastics and/or composite materials. The gaskets (1) are made of NBR, but they can also be made of its varieties or different types of EPDM, FKM and/or various plastics and/or composite materials. Connecting the heat exchanger components is made by screwing. It provides a wide range of applications of gasketed heat exchangers in industry, among others: energy, pharmaceutical, food, petrochemical, chemical, mining, at pool installations, HVAC, HVACR and in sewage treatment plants.
