Abstract

The utility model belongs to a plate heat exchanger part, in particular to a sealing gasket of a plate heat exchanger. The sealing gasket is in a closed ring shape integrally and comprises a main sealing surface which can be contacted with the surface of an adjacent plate and realize sealing, and two sealing surfaces which are matched with the outer sides of corner holes on the plate and can realize sealing with the corner holes, wherein the two sealing surfaces and the main sealing surface are integrally formed; the two sealing surfaces are matched with a diagonal hole arranged on the plate. The utility model solves the problem of low heat exchange efficiency caused by that the medium can only complete heat exchange in a short stroke of the same-side flow passage in the prior art, and has the advantages of long stroke of medium flowing in the plate, sufficient and good heat exchange, obvious temperature rise or temperature drop effect in unit time and the like.

Description

Sealing gasket for plate heat exchanger

Technical Field

The utility model belongs to a plate heat exchanger part, in particular to a sealing gasket of a plate heat exchanger.

Background

The plate heat exchanger is divided into three structures of a brazing type, a full welding type and a detachable type. The major structure of present removable plate heat exchanger is including a plurality of slabs that open and be equipped with the trompil, the angular hole of slab is used for two kinds of working medium to flow, the board laminating pressure equipment that the structure is the same, adjacent board is 180 reverse installations, one side trompil switches on about the runner of angular hole on the face, the opposite side does not switch on from top to bottom, the runner that forms on the adjacent face is the flow and the heat exchange that cross distribution is used for different working medium, be equipped with seal gasket between the adjacent board, seal gasket's effect prevents that working medium from leaking firstly, secondly, the runner that forms two kinds of working medium makes two kinds of media accomplish the heat exchange in the runner. The problem that the seal gasket of above-mentioned current product exists is because two are sealed designs in homonymy corner hole periphery, leads to the medium runner to switch on only between the homonymy trompil, forms the medium and can only accomplish the heat exchange in the short stroke of homonymy runner, and heat exchange efficiency is low, and the heat transfer effect is poor, and temperature rise or temperature drop effect in the unit interval are not good.

The product structure, performance requirements, manufacturing process, detection method and the like of the plate heat exchanger are clearly specified in the national people's republic of China industry standard (NB/T47004-.

The applicant does not find the same or similar literature reports after searching.

SUMMERY OF THE UTILITY MODEL

The utility model provides a sealing gasket of a plate heat exchanger, which achieves the purposes of increasing the heat exchange stroke of a medium between two adjacent plates and improving the heat exchange efficiency by improving the structure of the existing sealing gasket of the plate heat exchanger.

The overall technical concept of the utility model is as follows:

the plate heat exchanger sealing gasket is integrally in a closed ring shape and comprises a main sealing surface which can be contacted with the surface of an adjacent plate and realize sealing, and two sealing surfaces which are matched with the outer sides of corner holes on the plate and can realize sealing with the plate, wherein the two sealing surfaces and the main sealing surface are integrally formed; the two sealing surfaces are matched with a diagonal hole arranged on the plate.

The specific technical structure of the utility model is as follows:

in order to ensure the sealing effect of the two sealing surfaces and reduce the mechanical damage of the two sealing surfaces caused by pulling, the preferable technical implementation means is that a sealing strip is arranged between the outer side of the two sealing surfaces and the main sealing surface.

In order to facilitate assembly and avoid damage to the sealing surface, a preferred technical implementation means is that a gripping part extends from the outer side of the main sealing surface.

The utility model can be conveniently vulcanized and molded by adopting rubber materials.

The technical progress achieved by the utility model is as follows:

the two sealing surfaces in the utility model adopt a structural design matched with a pair of diagonally distributed corner holes, so that the sealing effect is effectively ensured, and meanwhile, compared with the sealing gasket with the existing structure, the sealing gasket can ensure that two media have long stroke flowing through the plate, the heat exchange is sufficient and good, and the temperature rise or temperature drop effect in unit time is obvious.
