Abstract
The utility model discloses a kind of rectangle snap-fastener gasket seal on heat-exchangers of the plate type, the gasket seal includes gasket body, it is characterized in that：Multiple snap-fasteners are provided with the outside of the gasket body top edge, and the snap-fastener is made up of symmetrically arranged two dowels and the rectangle snap-fastener main body being connected between two dowels, and the dowel is vertical with gasket body to be connected.This utility model is due to carrying two dowels, strengthen the bonding strength of rectangle snap-fastener and gasket body, improve the positioning precision of pad, performance so as to ensure sealing gasket for plate-type heat exchanger is normally played, the multiple utilization of pad in heat-exchangers of the plate type maintenance work is met, the maintenance cost of heat-exchangers of the plate type is reduced.
Description
Technical field
This utility model is related to the seal member on a kind of heat-exchangers of the plate type, and in particular to a kind of for board-like heat exchange
Rectangle snap-fastener gasket seal on device.
Background technology
Heat-exchangers of the plate type is made up of one group of corrugated thin metal plate, has hole on plate, and two kinds of liquid for exchanging heat lead to
Cross, wavy metal plate is in a framework for having fixed pressure plate and movable pressure plate in front and back, and is pressed from both sides with fishbolt
Tightly, fluid passage is sealed equipped with rubber sheet gasketing on plate, and it is respective logical to guide cold and hot fluid alternately to flow to
In road, the flow of fluid, physical property, pressure differential and temperature difference determine that the quantity and size of plate, corrugated plating are not only aggravated
Turbulent extent, and form many strong points, it is sufficient to bear the pressure differential between medium, between each plate, form rectangular channel,
Heat exchange is carried out by plate, so as to complete the conversion of the energy in the heat-exchangers of the plate type.
Heat-exchangers of the plate type of the plate using rubber sheet gasket sealing, general work pressure are less than 2.5MPa, operating temperature
It is less than 160 DEG C.The gasket seal of heat-exchangers of the plate type is fixed on plate two ways, and one kind will be sealed with bonding agent
Pad is affixed directly in the seal groove of plate, and another kind is fixed on plate by the snap-fastener on gasket seal, this pad
Piece is also referred to as free bonding pad, using free bonding pad, the repair and maintenance of heat-exchangers of the plate type can be made rapider, changes
Pad is convenient and swift, reduces maintenance cost.
Existing free bonding gasket construction is that multiple cylinder snap-fasteners by arranging thereon are connected with sheet edges at present, makes
Rubber cushion groove of the gasket seal on plate is neatly positioned, but this structure has certain shortcoming and defect, concrete manifestation：①
When gasket seal is connected with plate, snap-fastener is connected shakiness with sheet edges, and pad is easily channeled bit, deviates seal groove；2. on plate
Connecting hole position is thin, neighbouring seal groove, affects the intensity of seal groove；3. gasket seal and heat-exchangers of the plate type production and
In maintenance process snap-fastener be connected unstable phenomenon by button hole on plate and happen occasionally.The appearance of above-mentioned situation can make pad
The sealing function of piece declines causes leakage even to be failed, and affects the performance of heat-exchangers of the plate type, and when serious pad can lose
Lose free sticky function.
Content of the invention
The purpose of this utility model is to provide a kind of rectangle snap-fastener gasket seal on heat-exchangers of the plate type, the offer
A kind of rational in infrastructure, accurate positioning, the performance for being able to ensure that sealing gasket for plate-type heat exchanger, realize many of gasket seal
Secondary utilization, it is possible to decrease the maintenance cost of heat-exchangers of the plate type.
This utility model is achieved in that a kind of rectangle snap-fastener gasket seal on heat-exchangers of the plate type, and this is close
Gasket includes：Gasket body, is characterized in that：Multiple snap-fasteners, the snap-fastener are provided with the outside of the gasket body top edge
It is made up of symmetrically arranged two dowels and the rectangle snap-fastener main body being connected between two dowels, the dowel and pad
Piece body normal connects, during use, relevant position that gasket body is arranged on heat exchange plate, be machined with heat exchange plate with
The hole clipping that rectangle snap-fastener body shape matches, each rectangle snap-fastener main body pressing described is fixed in hole clipping to be realized fixing.
The beneficial effects of the utility model：
1st, this utility model is applied in dismountable board type heat exchanger and the board-like heat of half welding type due to adopting said structure
On exchanger, gasket seal is enable securely and precisely to be embedded in the seal groove of plate.
2nd, this utility model is due to two dowels, strengthening the bonding strength of rectangle snap-fastener and gasket body, carrying
The high positioning precision of pad, the performance so as to ensure sealing gasket for plate-type heat exchanger are normally played, are met
In heat-exchangers of the plate type maintenance work, the multiple utilization of pad, reduces the maintenance cost of heat-exchangers of the plate type.
3rd, the conventional material of pad described in the utility model has ethylene propylene diene rubber, nitrile rubber, fluorubber and neoprene rubber
Glue gasket.

Specific embodiment
Refer to Fig. 1,2,3,4,5, a kind of rectangle snap-fastener gasket seal on heat-exchangers of the plate type, the gasket seal bag
Include：Gasket body 1, is characterized in that：Multiple snap-fasteners 2 are provided with the outside of 1 top edge of the gasket body, the snap-fastener 2 is by right
Two dowels 3 for arranging and the rectangle snap-fastener main body 4 being connected between two dowels 3 is claimed to constitute, the dowel 3 and pad
The 1 vertical connection of piece main body, during use, gasket body 1 is arranged on heat exchange plate relevant position is machined with heat exchange plate
The hole clipping 5 matched with 4 shape of rectangle snap-fastener main body, each pressing of rectangle snap-fastener main body 4 described is fixed in hole clipping 5 to be realized admittedly
