Abstract
The utility model discloses an wrap seal gasket paper for the plate heat exchanger, which has two layers of compound structure button stem and a superficial layer, the button stem is the rubber based material, the button stem surface is enclosed by a superficial layer, which is a thermoplastic polymer resin. The utility model has the advantages of good seal, good elasticity, easy processing, resistance to the chemical corrosion, and is applicable to the heating exchanging workings status with the medium of organic solvent and tough corrosive medium.
Description
Technical field the utility model relates to a kind of parts of plate type heat exchanger, a kind of specifically plate type heat exchanger clad type gasket seal.
The background technology plate type heat exchanger is as a kind of efficient, energy-conservation heat transmission equipment, just be widely used in industrial many links, and the effect of the gasket seal of one of plate type heat exchanger critical component is exactly the function that realizes its sealing, and the gasket seal of extensive use at present mainly is that synthetic rubber, blended rubber or asbestos material are made.The gasket seal excellent spring that synthetic rubber, blended rubber are made though a large amount of the use retrains because of being subjected to factors such as heatproof, corrosion-resistant, chemically-resistant swelling, influences the normal use of plate type heat exchanger; Especially medium is in the heat exchange operating mode of Korrosionsmedium of organic solvent and comparison harshness; The gasket seal that the asbestos material is made because of processing difficulties, contain poisonous, harmful substance, and sealing effectiveness is poor, thereby use amount seldom, thereby has been limited the scope of application of plate type heat exchanger.
Utility model content the purpose of this utility model is to provide a kind of plate type heat exchanger clad type gasket seal, and its good sealing effect, excellent spring, easy to process, resistance to chemical attack are applicable in the Korrosionsmedium heat exchange operating mode of harshness and use.
To achieve these goals, the utility model adopts following technical scheme: plate type heat exchanger clad type gasket seal, and it has two layers of composite construction stem stem and top layer, and stem stem is a rubber substrate, the stem stem surface is coated with the top layer, and the top layer is the thermoplasticity macromolecule resin material.
Because the thermoplasticity macromolecule resin material, as polytetrafluoroethylene (PTFE), stable, corrosion-resistant, the anti-swelling of chemical property is good, but lack flexibility, the hardness height; The plate of plate type heat exchanger is very thin, as direct employing polytetrafluoroethylene (PTFE) or other thermoplasticity macromolecular material as gasket seal, though can solve problem corrosion-resistant, anti-swelling owing to lack flexibility and the hardness height, cause plate distortion easily, and be difficult to guarantee the reliability that seals.Adopt the gasket seal of said structure, it is composited by clad material and two kinds of materials with different properties of rubber substrate; Stem stem is the rubber substrate of excellent spring, and the top layer is the good polytetrafluoroethylene (PTFE) of corrosion-resistant, anti-swelling or other thermoplasticity macromolecule resin material; The excellent properties of two kinds of materials is integrated, make plate type heat exchanger clad type gasket seal have excellent elasticity and corrosion resistant performance simultaneously, so, good sealing effect, excellent spring, chemical mediator does not directly contact with rubber substrate, but directly contact with good polytetrafluoroethylene (PTFE) or other thermoplasticity macromolecule resin material of stable, corrosion-resistant, the anti-swelling of chemical property on top layer, make rubber substrate be in best etch-proof sealing state all the time; So, be applicable in the Korrosionsmedium heat exchange operating mode of harshness and use.
This use is novel mainly to have solved rubber substrate and polytetrafluoroethylene (PTFE) or the compound problem of other thermoplasticity macromolecular material in the plate type heat exchanger gasket seal, simultaneously the two is combined closely, the adhesive strength height, surfacing, meet the designing requirement of plate type heat exchanger gasket seal, and chemical mediator is not directly contacted with rubber substrate, thus improve the corrosion resistance of plate type heat exchanger gasket seal, guarantee that plate type heat exchanger can normally use in the operating mode of seriously corroded.Plate type heat exchanger of the present utility model can coat and sulfidization molding various difform gasket seals on request with gasket seal, satisfies the designing requirement of all size gasket seal.

The specific embodiment is explained in detail the utility model below in conjunction with accompanying drawing;
Embodiment 1 half clad type plate type heat exchanger gasket seals
As shown in Figure 1: seal with gasket seal 2 with plate type heat exchanger between adjacent two plates 1 of plate type heat exchanger.Fig. 2 illustrates a kind of contour structures of the utility model plate type heat exchanger with gasket seal 2, referring to Fig. 3 and Fig. 4, plate type heat exchanger has two layers of composite construction stem stem 201 and top layer 202 with gasket seal 2, stem stem 201 is rubber substrates, the side surface that stem stem 201 contacts with corrosive medium is coated with top layer 202, and top layer 202 is polytetrafluoroethylene (PTFE).This half clad type plate type heat exchanger is very good with gasket seal elasticity.
Referring to Fig. 5 and Fig. 6, plate type heat exchanger has two layers of composite construction stem stem 201 and top layer 202 with gasket seal 2, and stem stem 201 is rubber substrates, and stem stem 201 surfaces are coated with top layer 202 entirely, and top layer 202 is perfluoroethylene-propylenes.
Making of the present utility model needs through the specially-shaped sulfuration process, and the joint is through high temperature pressing abutting edge reason, does not have obviously unevenly, does not influence sealing property.
More than having provided the specific embodiment of the present utility model, and do not meant that restriction of the present utility model, can be perfluoroethylene-propylene as half clad type plate type heat exchanger with the top layer of gasket seal; Full clad type plate type heat exchanger can be a polytetrafluoroethylene (PTFE) with the top layer of gasket seal; No matter be half clad type plate type heat exchanger with the top layer of gasket seal, complete still the clad type plate type heat exchanger can be other thermoplasticity macromolecular material with the top layer of gasket seal.And the size of clad material and rubber substrate faying face and the shape of plate type heat exchanger gasket seal can be made into and can satisfy different all size and the shapes that require.Two layers of composite construction of every employing, stem stem is a rubber substrate, the top layer is the plate type heat exchanger gasket seal of thermoplasticity macromolecule resin material.All should belong to protection category of the present utility model.
