Description
Technical field
The utility model relates to heat transmission equipment, especially a kind of teflon heat exchanger.
Background technology
Fluoroplastics have the performances such as excellent dielectric properties and resistance to chemical attack, high-low temperature resistant, waterproof, sticky, low-friction coefficient, good self lubricity.It is the ideal material of making the heat exchanger of being able to bear strong corrosion.But because the thermal conductivity factor of this material is little, therefore all kinds of teflon heat exchanger heat exchanger tubes have all been selected minor diameter (being generally less than φ 6mm) light-wall pipe (thickness of pipe wall 0.3～0.5mm), therefore heat exchanger tube quantity is very big, owing to all having adopted fluoroplastics heat exchanger tube and being connected of tube sheet the fusion of heat expansion method; Fusion face between heat exchanger tube and the tube sheet of the fusion of heat expansion method is very narrow, and it is unreliable therefore to connect.Because heat exchanger tube quantity is very big, tube pitch is minimum simultaneously, and a large amount of fluoroplastics heat exchanger tubes and tube sheet fusion have increased again the difficulty of fusion, make to fuse into power and greatly reduce, and heat exchanger tube and tube sheet are very easily thrown off, and finally have influence on the quality and performance of heat exchanger.
Summary of the invention
For the deficiencies in the prior art, the utility model provides the syndeton of a kind of fluoroplastics tubular type heat exchanger heat-exchanging tube and tube sheet, and connected mode is simple, reliable, and good sealing effect.The technical solution adopted in the utility model is:
A syndeton for fluoroplastics tubular type heat exchanger heat-exchanging tube and tube sheet, comprises tube sheet, in described tube sheet, has pore, and pore has the extra heavy pipe hole that holds clamping sleeve and the tubule hole that holds fluoroplastics heat exchanger tube, is provided with chamfering in the junction in extra heavy pipe hole and tubule hole;
Fluoroplastics heat exchanger tube inserts in the tubule hole in tube sheet, the expansion mouth that one end of fluoroplastics heat exchanger tube coordinates with chamfering with the junction enlarging formation in tubule hole in extra heavy pipe hole;
One end of the clamping sleeve of hollow has the termination coordinating with the expansion mouth of fluoroplastics heat exchanger tube, clamping sleeve is inserted in the extra heavy pipe hole in tube sheet, clamping sleeve is connected with the inwall in extra heavy pipe hole, insert in the expansion mouth of fluoroplastics heat exchanger tube one end of clamping sleeve, by one end of clamping sleeve, fluoroplastics heat exchanger tube is pressed on tube sheet.
Further, described clamping sleeve is threaded connection, expanded joint or bonding way be connected with the inwall in extra heavy pipe hole.
Particularly, the material of described clamping sleeve and tube sheet is metal or nonmetal.
Further, the material of described clamping sleeve is iron, aluminium, copper, fluoroplastics, PP plastics or PVC plastics.
Further, the material of described tube sheet is iron, aluminium, copper, fluoroplastics, PP plastics or PVC plastics.
Advantage of the present utility model: because the mode that has adopted clamping sleeve to compress fluoroplastics heat exchanger tube has replaced original heat expansion method fusion process, make fluoroplastics heat exchanger tube and being connected of tube sheet become simple and convenient, connection reliability improves, can not reveal, fluoroplastics heat exchanger tube is free to disassembling, assembling and replacing simultaneously, heat exchanger tube for independent damage can be changed separately, has so greatly improved the service life of teflon heat exchanger.
Avoid the problem that the material of heat exchanger tube sheet in heat expansion method fusion process must be identical with heat exchanger tube material, because the mode that has adopted clamping sleeve compresses heat exchanger tube and tube sheet, therefore can need to select each metalloid or nonmetallic tube sheet and clamping sleeve material according to equipment and process, thereby reach instructions for use, increase substantially voltage endurance capability and the scope of application of heat exchange equipment.
Accompanying drawing explanation
Fig. 1 is structure composition schematic diagram of the present utility model.
The specific embodiment
Below in conjunction with concrete drawings and Examples, the utility model is described in further detail.
As shown in Figure 1: the syndeton of a kind of fluoroplastics tubular type heat exchanger heat-exchanging tube and tube sheet, comprises tube sheet 1, clamping sleeve 2 and fluoroplastics heat exchanger tube 3.
In tube sheet 1, have pore 4, pore 4 has the extra heavy pipe hole 41 and the tubule hole 42 that holds fluoroplastics heat exchanger tube 3 that hold clamping sleeve 2, is provided with chamfering 5 in extra heavy pipe hole 41 and the junction in tubule hole 42.Fluoroplastics heat exchanger tube 3 inserts in the tubule hole 42 in tube sheet 1, the expansion mouth 31 that one end of fluoroplastics heat exchanger tube 3 coordinates with chamfering 5 with the junction enlarging formation in tubule hole 42 in extra heavy pipe hole 41.
One end of the clamping sleeve 2 of hollow has the termination coordinating with the expansion mouth 31 of fluoroplastics heat exchanger tube 3, the external diameter of this termination is less than the external diameter of clamping sleeve 2 other parts, but be greater than the internal diameter of fluoroplastics heat exchanger tube 3, clamping sleeve 2 is inserted in the extra heavy pipe hole 41 in tube sheet 1, clamping sleeve 2 is connected with the inwall in extra heavy pipe hole 41, insert in the expansion mouth 31 of fluoroplastics heat exchanger tube 3 one end of clamping sleeve 2, one end by clamping sleeve 2 is pressed on fluoroplastics heat exchanger tube 3 on tube sheet 1, thereby reach the tight laminating of heat exchanger tube and tube sheet, heat transferring medium can enter heat exchanger tube 3 by the clamping sleeve of hollow 2, thereby reach the object of heat exchange.
The material of clamping sleeve 2 and tube sheet 1 can adopt metal or nonmetallic materials according to design conditions and environment, thus the safe operation of the equipment of assurance.Particularly, the material of clamping sleeve 2 can be selected iron, aluminium, copper, fluoroplastics, PP(polypropylene) plastics or PVC(polyvinyl chloride) plastics.The material of tube sheet 1 also can be selected iron, aluminium, copper, fluoroplastics, PP(polypropylene) plastics or PVC(polyvinyl chloride) plastics.
In clamping sleeve 2 and tube sheet 1, the connected mode of extra heavy pipe hole 41 inwalls, is guaranteeing that the situation that clamping sleeve can compress is little, can adopt be threaded, expanded joint, the various ways such as bonding.
The utility model has adopted clamping sleeve to compress the technical scheme of fluoroplastics heat exchanger tube, good sealing effect, connected mode is simple, comparatively flexible to the requirement of the materials such as tube sheet, be convenient to disassembling, assembling and replacing, solve the problem existing in existing teflon heat exchanger manufacturing technology, increased substantially the scope of application of teflon heat exchanger, reduced the risk in manufacture and use.Therefore fundamentally solving manufacture craft defect and performance deficiency that various countries exist for many years on teflon heat exchanger is manufactured always, range of application is wider.
