Description
Technical field
The present invention relates to heat-exchangers of the plate type to fabricate field, is to be related between plate heat exchanger plate to seal the gasket seal used specifically.
Background technology
Heat-exchangers of the plate type is a kind of efficient, energy-conservation, compact heat transmission equipment, has heat transfer efficiency high, compact-sized, floor space is small, has a wide range of application, and installs the advantages that easy to clean.Its core parts are plate and gasket seal, and gasket seal is the key element of dismountable board type heat exchanger, and the quality of its quality has a direct impact with temperature resistant capability, service behaviour and accommodation etc. to pressure-resistant.Its material of the gasket seal used in heat-exchangers of the plate type is mostly nitrile rubber, ethylene propylene diene rubber or fluorubber etc. for a long time, their popular feature is that elasticity is good, compression ratio is big, good sealing effect, but with market demand more and more higher, the limitation that several material gasket seals use also gradually highlights.Especially temperature in use is restricted with pressure, and 110 DEG C of the fine seal gasket maximum operation (service) temperature of fourth, 150 DEG C of EPDM seal gasket maximum operation (service) temperature, fluorine seal gasket maximum operation (service) temperature also just reaches 180 DEG C.And it is usually no more than 1.0Mpa using pressure.This will undoubtedly expose the defects of conventional gasket seal exists under high temperature, hyperbaric environment state.So that the application of heat-exchangers of the plate type is restricted, and directly affects and govern the survival and development of enterprise.Therefore, the selection of sealing gasket for plate-type heat exchanger is become as field technical barrier anxious to be resolved.
The content of the invention
It is an object of the invention to provide a kind of gasket seal for heat-exchangers of the plate type, it can effectively improve the heatproof of gasket seal or even heat-exchangers of the plate type, pressure-resistant ability to bear and reliably seal, the problem of substantially widening the application of heat-exchangers of the plate type, prior art being present is resolved.
A kind of gasket seal for heat-exchangers of the plate type of the present invention, the gasket seal are to be prepared using oil resistant without asbestos rubber material, and described oil resistant is NY4250 without asbestos rubber.
The thickness of the gasket seal is 3.5-4.0 mm.
The gasket seal bears 250 DEG C of maximum temperature, maximum pressure 1.6Mpa.
The gasket seal compression ratio is 7-12%.
Present invention advantages below had compared with prior art and good effect：
1. overcome technology prejudice；The oil resistant generally believes that its hardness is of a relatively high, elasticity is small without asbestos rubber in those skilled in the art, can not possibly be as the gasket seal of heat-exchangers of the plate type, but, the present invention has broken routine and traditional concept, overcome the technology prejudice in industry, oil resistant is organically combined without asbestos rubber gasket seal and heat-exchangers of the plate type, started oil resistant without asbestos rubber plate heat exchanger applications the beginning, through field experiment, unexpected technique effect is received, makes the present invention that there are substantive distinguishing features.
2nd, heat resistance is superior；Temperature in use of the present invention reaches as high as 250 DEG C, 70-140 DEG C is improved than existing heat-exchangers of the plate type tolerable temperature, and because oil resistant is without the unique institutional framework of asbestos rubber, aging or embrittlement will not be also produced at high operating temperatures, therefore higher sealing property and stable mechanical performance can be kept, and good sealing property can be also played during fluid oscillation.
3. bearing capacity is stronger；Oil resistant is small without asbestos rubber gasket seal compression ratio（Compression ratio is 7-12%）, rebound degree is limited, is unlikely to deform, and the present invention is exactly that make use of this feature, to bear board-like internal heat exchanger Fluid pressure, while increases clamping force.Through the oil resistant to thickness 3.6mm without asbestos seal gasket in V series heat-exchangerss of the plate type once installation suppress experiment 1.6MPa do not reveal.And repeated disassembled and assembled plate does not produce deformation（Plate is had no adverse effects）.Turn into undeniable reality in the application of heat-exchangers of the plate type so as to further demonstrate hard sealing structure pad.
4. oil resistant is free of asbestos, nontoxic non-stimulated smell, also without combustible, to human body and environment non-hazardous, safety and environmental protection without asbestos rubber gasket seal.
5. preparation technology is simple, dismounting is easy to clean；The present invention is by being laser-cut into gasket seal shape not of uniform size by oil resistant without asbestos packing sheet, surfacing, one plate can cut out a piece of cloth in a way with the minimum material to make two or more articles of clothing model of different sizes, due to sheet metal thickness tolerance very little, clamping force is uniform, the problem of outward appearance for substantially overcoming conventional plate easily to occur in installation is uneven, and plate seal groove deformation etc. influences product appearance quality.In the past because conventional hermetic pad temperature in use is limited, pipe heat exchanger or full-welding plate-type heat exchanger must be used by running into worst hot case, and this adds equipment manufacturing costs with regard to invisible, and equipment once blocks, and can not dismount.The present invention can bear high temperature and high pressure condition, also using the anti-sticking layer above and below pad, make dismounting more convenient with cleaning.
6. application is more extensive；The present invention is together with material intrinsic advantage is organically combined with heat-exchangers of the plate type monopolizing characteristic, plate heat exchanger applications field is set further to widen, oil resistant is exactly good heatproof with more than without asbestos rubber gasket seal, it is pressure-resistant, oil resistant, media-resistant and air-tightness, so there is wide applicability, it is widely used in generating electricity, it is metallurgical, ship, the all trades and professions such as petrochemical industry, be particularly suitable for use in industrial water, steam, oil, the stronger acid of industrial corrosion, alkali, the raw material of food, the cold and hot exchange of the media such as vitamin, and this gasket seal is resistant to various chemical mediators, it is sufficiently used for synthesizing oil/grease, alcohol, gasoline, solvent, cooling agent, antifreezing agent, the various operating modes such as salt use, with vast potential for future development.
Embodiment
A kind of gasket seal for heat-exchangers of the plate type of the present invention, it is to use high level aramid fiber and artificial rock wool（Sepiolite）For reinforcing material（That is filler）, using natural rubber, butylbenzene or NBR as adhesive, organic and inorganic fiber is free of asbestos, combination property is superior through the special sheet material formed of rolling depression method i.e. NY4250 oil resistants as framework without asbestos packing sheet, the plate 100%.By NY4250 oil resistants that the thickness of preparation is 3.6mm without asbestos packing sheet, through being laser-cut into the gasket seal that the shape corresponding with plate seal groove is the present invention.Its main technical characteristics see the table below 1：
The oil resistant of table 1 is without asbestos rubber gasket seal main technical characteristics
Its heat resistance of the gasket seal of the present invention is superior, bearing capacity is relatively strong, non-toxic and safe is environmentally friendly, preparation technology is simple, dismounting is easy to clean, heat-exchangers of the plate type can be made further to widen application field on the original basis, it is more widely used.
