Abstract
The utility model provides a kind of sealing structure for heat exchanger, including：, there is the crawler type bulge of positioning in crawler type positioning bulge, double-round sealing, leakage signal hole in the circumferential distribution of the gasket seal, are distributed on heat transferring plate and are provided with locating slot；In the locating slot of the accurate insert plate on piece of bulge in the sealing structure, accurate positioning does not shift, simple installation, bearing capacity higher.Leakage signal hole is designed in sealing structure, when medium has leakage, can expose at the first time from telltale hole, the mutually mixed of media of both sides will not be caused, securely and reliably.The utility model positioning is not required any glue kind to bond, and is more convenient, and cost is lower, and operation is more reliable.And it is possible to the later stage is avoided to cause to corrode to plate due to the use of glue kind is improper.
Description
Technical field
The utility model belongs to heat exchanger technical field of sealing technology more particularly to a kind of sealing structure for heat exchanger.
Background technology
Heat exchanger as a kind of high-efficiency heat exchanger equipment, be widely used in Heating,Ventilating and Air Conditioning, electric power, petrochemical industry, food pharmaceutical,
The industry-by-industries such as ship, Ferrous Metallurgy.And the critical component in heat exchanger is heat transfer element and gasket seal.The knot of gasket seal
Structure directly influences property easy to use, cost, recycling rate of waterused and the service life of product.
At present, in plate heat exchanger field, the structure of sealing ring is traditional flat type, and cross sectional shape is different, more
Commonly pentagonal configuration.Such sealing structure can change in actual process application because of the pulsed of system pressure, and
It generates sealing structure to shift and then heat exchanger is caused to be revealed, generates production hidden danger.The utility model is exactly a kind of brand-new
Seal style can solve sealing ring and the reliability and accuracy of plate positioning, particularly when system boot, easily generate
System pressure jump or pulsed variation, this structure can resist the mutation of such pressure.Bulge in sealing structure is accurate
In the locating slot of insert plate on piece, accurate positioning does not shift, simple installation, bearing capacity higher, and system run all right is stronger.
Therefore, the prior art is defective, it is necessary to improve.
The content of the invention
Technical problem to be solved in the utility model is in view of the deficiencies of the prior art, to provide a kind of heat exchanger sealing
Structure.
The technical solution of the utility model is as follows：
A kind of sealing structure for heat exchanger, including：There is the crawler type bulge of positioning in the circumferential distribution of gasket seal,
Crawler type bulge is accurately embedded in the locating slot being distributed on heat exchange core plate on gasket seal；It is additionally provided with and lets out on gasket seal
Reveal telltale hole；Double-round sealing is made of inner seal item and outside seal strip, and formation two is arc-shaped.
Wherein, certain series arrangement is pressed in the crawler type bulge.Gasket seal and crawler type bulge, double-round sealing and leakage
Telltale hole is ethylene propylene diene rubber, nitrile rubber or fluorubber using material of the same race.Leakage signal hole is arranged at gasket seal
Long side on, positioned at double-round sealing twice edge between.
The beneficial effects of the utility model are：The utility model positioning relies on what is carried in sealing structure to be arranged by certain sequence
The positioning bulge of row is not required any glue kind to bond, and is more convenient, cost is lower, and accurate positioning does not shift, simple installation, pressure-bearing
Ability higher, and plate can be caused to corrode due to the use of glue kind is improper to avoid the later stage.
Description of the drawings
Fig. 1 is the structure diagram of the utility model.
Specific embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in detail.
Embodiment 1
As shown in Figure 1, the utility model provides a kind of sealing structure for heat exchanger, there have in the circumferential distribution of gasket seal to be fixed
The crawler type bulge 1 of position, crawler type bulge 1 is accurate on gasket seal is embedded in the locating slot being distributed on heat exchange core plate；
Leakage signal hole 3 is additionally provided on gasket seal, when medium has leakage, can be exposed at the first time from leakage signal hole 3；It is double
Circle sealing 2 is two arc-shaped positions in figure, is made of inner seal item and outside seal strip, therefore referred to as double-round seals,
Effect is when wherein one sealing destroys, and fluid can be flowed out by leakage signal hole in time, can be sent out at the first time
Existing failure, and second sealing at this time can still serve close, and two media is avoided mutually to mix.Wherein, the effect of Inner arc is by one
Kind Fluid Sealing makes it not enter the region at center, and the effect of external arc is second sealing, when being revealed at Inner arc, stream
Body exposes at leakage signal hole, can be found in time.
Crawler type bulge 1, double-round sealing 2 and leakage signal hole 3 on gasket seal and gasket seal use material of the same race
Matter, can be ethylene propylene diene rubber, nitrile rubber, fluorubber etc..
Furthermore, including：There is the crawler type bulge 1 of positioning in the circumferential distribution of gasket seal, in gasket seal
In the locating slot being distributed on the accurate embedded heat exchange core plate of upper crawler type bulge 1, accurate positioning does not shift, simple installation, pressure-bearing
Ability higher.Leakage signal hole 3 is designed in sealing structure, is arranged in the long side of gasket seal, positioned at the two of double-round sealing
Between road edge, it when medium has leakage, can expose at the first time from leakage signal hole 3, the mutually mixed of media of both sides will not be caused,
Securely and reliably.The utility model positioning is not required any glue kind to bond, and is more convenient, and cost is lower, and operation is more reliable.It also, can
Plate is caused to corrode due to the use of glue kind is improper to avoid the later stage；
In above-mentioned, including：Crawler type positioning bulge 1, double-round sealing 2, leakage signal hole 3, in the week of the gasket seal
While the crawler type bulge 1 of positioning is distributed with, it is distributed on heat transferring plate and is provided with locating slot.
The utility model has the advantages that：The utility model positioning is by carrying in sealing structure by certain series arrangement
Bulge is positioned, any glue kind is not required to bond, is more convenient, cost is lower, and accurate positioning does not shift, simple installation, bearing capacity
Higher, and plate can be caused to corrode due to the use of glue kind is improper to avoid the later stage.
The beneficial effects of the utility model are：The utility model positioning relies on what is carried in sealing structure to be arranged by certain sequence
The positioning bulge of row is not required any glue kind to bond, and is more convenient, cost is lower, and accurate positioning does not shift, simple installation, pressure-bearing
Ability higher, and plate can be caused to corrode due to the use of glue kind is improper to avoid the later stage.
It should be appreciated that for those of ordinary skills, can be improved or converted according to the above description,
And all these modifications and variations should all belong to the protection domain of the appended claims for the utility model.
