Abstract
The utility model discloses the metal gasket of a kind of plate type heat exchanger, described metal gasket is one-body molded, metal gasket includes cylindrical portion, cylindrical turn-up portion and inner circle turn-up portion, described cylindrical turn-up portion and inner circle turn-up portion lay respectively at cylindrical portion two ends, and it being perpendicular to cylindrical portion, described cylindrical turn-up portion is identical with the internal diameter of inner circle turn-up portion.This utility model advantage compared with existing correlation technique is: metal gasket structural integrity molding of the present utility model, solderless contact, does not the most exist and is completely embedded between weldering leak, and heat exchanger fixed pressure plate, good sealing effect.
Description
Technical field
This utility model relates to tube-like interface gasket construction, particularly relates to a kind of plate-type heat-exchange
The metal gasket of device.
Background technology
Existing plate type heat exchanger metal gasket is that split welds fabricated structure, by cylindrical
Ring plate, interior circular ring plate are welded mutually with middle part cylinder, this gasket construction each composition portion
There is the solder joint of projection between part, and necessarily deposit between the fixed pressure plate of plate type heat exchanger
At gap and weldering leak, have a strong impact on the sealing of heat exchanger.
Utility model content
This utility model is to solve above-mentioned deficiency, it is provided that a kind of plate type heat exchanger is used
Metal gasket.
Above-mentioned purpose of the present utility model is realized by following technical scheme: a kind of plate
The metal gasket of formula heat exchanger, it is characterised in that: described metal gasket is one-body molded,
Metal gasket includes cylindrical portion, cylindrical turn-up portion and inner circle turn-up portion, described cylindrical flange
Portion and inner circle turn-up portion lay respectively at cylindrical portion two ends, and are perpendicular to cylindrical portion, described outside
Circle turn-up portion is identical with the internal diameter of inner circle turn-up portion.
The thickness of described cylindrical turn-up portion and inner circle turn-up portion is 1.5-2mm.
The internal diameter of described cylindrical turn-up portion and inner circle turn-up portion is 32mm-500mm.
Described cylindrical turn-up portion external diameter turns over more than inner circle turn-up portion external diameter 5-80mm or cylindrical
Edge external diameter is equal to inner circle turn-up portion external diameter.
It is provided with sealing gasket, it is ensured that the sealing being connected with ring flange outside described cylindrical turn-up portion
Property.
This utility model advantage compared with existing correlation technique is: gold of the present utility model
Belong to gasket construction one-body molded, solderless contact, the most there is not weldering leak, solid with heat exchanger
Determine to be completely embedded between pressure strip, good sealing effect.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the structural representation that this utility model is arranged on heat exchanger fixed pressure plate
Figure.
Fig. 3 is making of the present utility model and flow of installation schematic diagram.
Detailed description of the invention
Below in conjunction with the accompanying drawings this utility model is described in further detail.
As it is shown in figure 1, the metal gasket of a kind of plate type heat exchanger, described metal gasket
One-body molded, metal gasket includes cylindrical portion 1, cylindrical turn-up portion 2 and inner circle turn-up portion
3, described cylindrical turn-up portion 2 and inner circle turn-up portion 3 lay respectively at cylindrical portion 1 two ends,
And it is perpendicular to cylindrical portion 1, described cylindrical turn-up portion 2 and the internal diameter phase of inner circle turn-up portion 3
With.
The thickness of described cylindrical turn-up portion 2 and inner circle turn-up portion 3 is 1.5-2mm.
The internal diameter of described cylindrical turn-up portion 2 and inner circle turn-up portion 3 is 32mm-500mm.
Described cylindrical turn-up portion external diameter turns over more than inner circle turn-up portion external diameter 5-80mm or cylindrical
Edge external diameter is equal to inner circle turn-up portion external diameter.
It is provided with sealing gasket 4, it is ensured that be connected with ring flange outside described cylindrical turn-up portion 2
Sealing.
It is fixed and clamped as in figure 2 it is shown, metal gasket of the present utility model is arranged on heat exchanger
In four holes 6 of plate 5, metal gasket is completely embedded with heat exchanger fixed pressure plate, close
Envelope property is good.
As it is shown on figure 3, making of the present utility model and mounting process:
First, take one piece of sheet metal, and strike out "T"-shaped cylinder, then, by " T "
Shape wound packages enters in the hole of heat exchanger fixed pressure plate, at another of heat exchanger fixed pressure plate
Side carries out punching press again, after going out valgus, continues punching press, makes "T"-shaped cylinder final
Form " work " shape cylinder, i.e. molding.
The foregoing is only embodiment of the present utility model, not thereby limit this practicality new
The scope of the claims of type, every utilizes what this utility model description and accompanying drawing content were made etc.
Efficient construction or equivalence flow process conversion, or directly or indirectly it is used in other relevant technology necks
Territory, is the most in like manner included in scope of patent protection of the present utility model.
