Abstract
The utility model discloses a kind of connection of heat exchanger to collect effective plug, and it is related to technical field of heat exchangers；One end of the bourdon's tube is provided with hemispherical plug body, the other end of the bourdon's tube is provided with branch pipe two, several mounting holes are provided with the side wall of the bourdon's tube, branch pipe one is installed in the mounting hole, it is minimum wall thickness (MINI W.) at the plug of the hemispherical plug body, and the wall thickness at plug to edge progressively thickens；The utility model is reasonably assigned with the wall thickness of hemispherical plug, alleviates plug weight, reduces cost；Next reduces the labor content of hemispherical plug, shortens the production cycle, improves production efficiency；Finally reduce the stress concentration at plug and Tube-sheet Welding, reasonably control the stress distribution of plug and tube sheet, extend the service life of heat exchanger, improve the security of heat exchanger.
Description
Technical field：
It the utility model is related to a kind of heat exchanger connection and collect effective plug, belong to technical field of heat exchangers.
Background technology：
The connection of existing heat exchanger collects effective end sealing and uses welded seal after spinning, wall thickness skewness after spinning
It is even, leakage is easily broken when in use, and process is lost time.
Utility model content：
In view of the above-mentioned problems, the technical problems to be solved in the utility model is to provide, a kind of heat exchanger connection collection is effective to be blocked up
Head.
A kind of heat exchanger connection of the present utility model collects effective plug, and it includes hemispherical plug body, bourdon's tube, branch pipe
First, branch pipe two；One end of the bourdon's tube is provided with hemispherical plug body, and the other end of the bourdon's tube is provided with branch pipe two,
Several mounting holes are provided with the side wall of the bourdon's tube, branch pipe one, the hemispherical plug body are installed in the mounting hole
Plug at be minimum wall thickness (MINI W.), and the wall thickness at plug to edge progressively thickens.
Preferably, the branch pipe one is arc.
Compared with prior art, the beneficial effects of the utility model are：The wall thickness of hemispherical plug is reasonably assigned with, is subtracted
Light plug weight, reduces cost；Next reduces the labor content of hemispherical plug, shortens the production cycle, improves
Production efficiency；Finally reduce the stress concentration at plug and Tube-sheet Welding, reasonably control the stress of plug and tube sheet
Distribution, the service life of heat exchanger is extended, improve the security of heat exchanger.
Brief description of the drawings：
For ease of explanation, the utility model is described in detail by following specific implementations and accompanying drawing.
Fig. 1 is structural representation of the present utility model；
Fig. 2 is the structural representation of branch pipe one in the utility model.
In figure：1- hemispherical plug bodies；2- bourdon's tubes；3- branch pipes one；4- branch pipes two.
Embodiment：
To make the purpose of this utility model, technical scheme and advantage of greater clarity, below by what is shown in accompanying drawing
Specific embodiment describes the utility model.However, it should be understood that these descriptions are merely illustrative, and it is not intended to limit this reality
With new scope.In addition, in the following description, the description to known features and technology is eliminated, to avoid unnecessarily mixing
Confuse concept of the present utility model.
As shown in Figure 1-2, present embodiment uses following technical scheme：It includes hemispherical plug body 1, bourdon's tube
2nd, branch pipe 1, branch pipe 24；One end of the bourdon's tube 2 is provided with hemispherical plug body 1, the other end peace of the bourdon's tube 2
Equipped with branch pipe 24, several mounting holes are provided with the side wall of the bourdon's tube 2, branch pipe 1, institute are installed in the mounting hole
It is minimum wall thickness (MINI W.) to state at the plug of hemispherical plug body 1, and the wall thickness at plug to edge progressively thickens.
Further, the branch pipe 1 is arc.
The operation principle of present embodiment is：By the quick sealing of pipe end, make from air inlet pipe inflow heat exchanger
Fluid carries out seepage flow, fluid is evenly distributed on laterally and longitudinally in heat exchanger by isocon one, two, realizes heat exchange
Fluid tissue in device is uniformly distributed, and improves heat exchange efficiency, increases heat exchange amount, reduces heat exchange area.Reasonably it is assigned with first
The wall thickness of hemispherical plug, plug weight is alleviated, reduces cost；Next reduces the labor content of hemispherical plug,
The production cycle is shortened, improves production efficiency；Finally reduce the stress concentration at plug and Tube-sheet Welding, reasonably control
The stress distribution of plug and tube sheet, the service life of heat exchanger is extended, improve the security of heat exchanger.
The advantages of general principle and principal character of the present utility model and the utility model has been shown and described above.One's own profession
The technical staff of industry is it should be appreciated that the utility model is not restricted to the described embodiments, described in above-described embodiment and specification
Simply illustrate principle of the present utility model, on the premise of the spirit and scope of the utility model is not departed from, the utility model is also
Various changes and modifications are had, these changes and improvements are both fallen within claimed the scope of the utility model.The utility model
Claimed scope is by appended claims and its equivalent thereof.
