Specific embodiment
Specific embodiments of the present invention are described in detail below in conjunction with attached drawing.It should be understood that described herein
Specific embodiment be merely to illustrate and explain the present invention, be not intended to restrict the invention.
Below with reference to the accompanying drawings pipeline jointing construction for refrigerating plant and refrigerating plant according to the present invention are described
The connection method of compressor circuit.
Referring to Figure 2 to Figure 4, the exemplary embodiment of the present invention provides a kind of connections of the compressor circuit of refrigerating plant
Method, this method comprises:
Coupling ring 1 is set on device pipeline 2 to be connected；
The interpolation pipe of the front of device pipeline 2 outer tube of the inserting of section 21 to the front of compressor circuit 3 of plugging into is plugged into
In the lumen of section 31；And
Coupling ring 1 is moved along pipeline and is tightly placed in outer tube and is plugged into section 31, section 31 and interpolation so that outer tube is plugged into
Pipe, which is plugged into, forms circumferential crimping sealing between section 21；
Wherein, coupling ring 1 includes the coupling ring sets of holes of truncated cone-shaped and wealthy 11 He of mouth end of coupling ring positioned at axial ends
Coupling ring slot end 12, the sets of holes aperture at the wealthy mouth end 11 of coupling ring are greater than outer tube and plug into the outer tube diameter of section 31, coupling ring slot
The sets of holes aperture at end 12 be greater than interpolation pipe plug into section 21 outer tube diameter and be less than outer tube and plug into the outer tube diameter of section 31.
It should be noted that being forward along the direction that the pipeline connection close to compressor circuit 3 and device pipeline 2 moves
Moving direction, and be front close to the part of the pipeline connection.It is connect along the pipeline far from compressor circuit 3 and device pipeline 2
The direction of the place's of refuting movement is to move backward direction, and the part far from the pipeline connection is rear portion.In addition, compressor circuit 3
It may include compressor exhaust pipe 34, compressor return air pipe 35 and Compressor Process pipe 36 etc., device pipeline 2 can be electrical part
Extended conduit is also possible to the transitional connection pipe road etc. connected for transition.For example, when refrigerating plant is refrigerator, device pipe
Road 2 may include refrigerator evaporation tube road, refrigerator return-air transition pipe and refrigerator process duct etc..In addition, the refrigerating plant can also be
Refrigerator or air-conditioning etc., will not enumerate herein.
Due to usually first each component in refrigerating plant to be installed, then to different components before pipeline of plugging into
Between pipeline plug into, therefore the rear end of compressor circuit 3 has been pre-attached to compressor, and the rear end of device pipeline 2
It has been pre-attached to corresponding component.In other words, when coupling ring 1 to be set in the device pipeline 2 wait connect, usually from dress
Set what the front end of pipeline 2 penetrated.And since the sets of holes pore size to the wealthy mouth end 11 of coupling ring and coupling ring slot end 12 carries out
It limits, therefore more specifically, the front end of device pipeline 2 is penetrated from coupling ring slot end 12.Otherwise, if it is wealthy from coupling ring
Mouthful end 11 penetrates, and wants small compared with the plug into outer tube diameter of section 31 of outer tube in view of the sets of holes aperture at coupling ring slot end 12, it may be difficult to
It coupling ring 1 is moved to outer tube along pipeline plugs into section 31 after inner and outer pipes inserting, to can not plug into section 31 in outer tube
It plugs into be formed between section 21 with interpolation pipe and circumferential crimps sealing.
In the prior art, if directlying adopt coupling ring with sleeve joint device pipeline and compressor circuit respectively, there can be pipe
Road tolerance, surface accuracy, fit dimension and syndeton length etc. with the mutual unmatched technical difficulty of coupling ring.In this structure
Under, the leak rate of pipeline connection is taller compared with gas brazing, it is clear that does not meet actual operation requirements.And in example of the invention
Property embodiment method in, by the way that device pipeline 2 and compressor circuit 3 are mutually inserted, and utilize coupling ring 1 carry out hoop pressure
Tightly, device pipeline 2 and compressor circuit 3 can be made to be formed as being interference fitted from clearance fit, effectively overcome pipeline tolerance etc.
Technical difficulty advantageously reduces leak rate to form the stronger pipeline jointing construction of leakproofness, to improve the stabilization of refrigerating plant
Property and reliability.In addition, requirement of this method to operating space size is low compared with gas brazing, assembling process is quick and smooth, grasps
Make simple and inflammable toxic gas is not present, coupling ring is easily obtained in addition, therefore security reliability is higher, to operator's
Skills and experience is of less demanding, is substantially shorter the training time on duty, can be relieved manufacturing business to a certain extent due to personnel
Government pressure caused by turnover rate is high, and difficulty of processing and processing cost can be significantly reduced.
It should be strongly noted that requirement of the method for exemplary embodiment of the present invention for operating space is extremely low.Example
Such as, it is conventionally formed with that outer tube plugs into section 31 and the plug into pipeline of section 21 of interpolation pipe is plugged into receiving for accommodating in refrigerating plant
Chamber, when using the present method, pipeline plug into accommodating chamber volume no more than 150cm2In the case where, it is able to achieve quick and smooth
Assembly, therefore ultrahigh in efficiency.If but this pipeline plug into accommodating chamber volume under carry out gas brazing, difficulty of processing pole
Greatly, it and is easy to burn out periphery electrical part, reliability and efficiency are extremely low.
In some embodiments, coupling ring 1 is moved along pipeline and is tightly placed in outer tube and plugged into section 31 further include: so that
Coupling ring slot end 12 be moved to outer tube plug into section 31 periphery wall on.It plugs into when coupling ring slot end 12 is moved to outer tube
Section 31 periphery wall on when, that is, show coupling ring 1 be only set in outer tube plug into section 31 periphery wall on, and no longer with interpolation pipe
There are any contacts for section of plugging into 21, it is ensured that the tightening force of coupling ring 1 all acts on outer tube and plugs into section 31, to guarantee outer
The plug into peripheral wall of section 31 of casing can generate expected deformation, and being plugged into interpolation pipe is formed suitable interference between section 21 and match
It closes.
In the pipeline jointing construction assembled by the above method, the plug into front of section 31 of outer tube is formed as outer tube diameter
The crimping reducing diameter part 32 of diminution, crimping reducing diameter part 32, which includes that outer diameter is identical with the sets of holes aperture at coupling ring slot end 12, crimps contracting
Diameter front and the crimping reduced diameter back section being bonded with the sets of holes internal perisporium of coupling ring sets of holes.In other words, crimping reduced diameter back section is connection
Connect ring 1 and outer tube plug into and generates the critical part of contact between section 31, crimping undergauge front with crimp between reduced diameter back section
It plugs into a section part, the plug into outer tube diameter of section 31 of outer tube is greater than the sets of holes aperture of coupling ring 1, therefore the banding by coupling ring 1
Effect, so that outer tube is plugged into, section 31 and interpolation pipe section 21 of plugging into are formed and are interference fitted.The outer tube diameter of section 31 and outer tube is plugged into
Less than the part in the sets of holes aperture of coupling ring 1, then not formed effective contact.
To improve leakproofness, preferably restriction outer tube plugs into the crimping reducing diameter part 32 of section 31 and interpolation pipe is plugged into section 21
Magnitude of interference is 0.03mm~0.08mm.When magnitude of interference is less than 0.03mm, leakproofness is insufficient, and leak rate cannot be effectively reduced.It has served as
When the amount of being full of is greater than 0.08mm, the elastic deformation limit of pipeline can be exceeded, and be formed as not recoverable plastic deformation, be unfavorable for protecting
Demonstrate,prove the strength character etc. of pipeline.
In addition, to further increase the leakproofness between inner and outer pipes, in some embodiments, the above method further include: will
Sealing fluid 4 filling to outer tube plug into section 31 internal perisporium and interpolation pipe plug into section 21 periphery wall between.For example, can be used close
To realize the method step, which both may be configured as being manually operated sealing liquid material injecting device 7, may be alternatively provided as
Full automatic working.For example the mode automatic ration of cylinder and controller, fixation can be used to carry out accurately dripping glue, thus preferably
Solve sealing fluid it is excessive, it is very few or there are caused by position deviation etc. pollution or leakage problem.
Specifically, sealing fluid 4 is filled to outer tube and plugs into the internal perisporium of section 31 and interpolation pipe is plugged into the periphery wall of section 21
Between include:
Put interpolation pipe section 21 of plugging into diagonally downward；
It is connect by the interpolation pipe of the front of device pipeline 2 outer tube of the inserting of section 21 to the front of compressor circuit 3 of plugging into
Before refuting in the lumen of section 31, by the drop of sealing fluid 4 interpolation pipe plug into section 21 rear portion periphery wall on so that close after inserting
Sealing liquid 4 can flow that outer tube plugs into the internal perisporium of section 31 and interpolation pipe is plugged into the periphery of section 21 to be filled in along pipeline periphery wall
Between wall.
Preferably to control the flowing velocity of sealing fluid and in view of factors such as the curing times of sealing fluid, need to limit
Interpolation pipe is plugged into the angle that section 21 is put diagonally downward.In practice, compressor circuit 3 can be preset with respect to the horizontal plane
Upward slanted angle, at this time either machine operation either manual operation, only interpolation pipe need to be plugged into section 21 adaptively
Inserting can be obtained required inclination and put angle into the compressor circuit 3.Preferably, compressor circuit 3 is relative to level
The upward slanted angle in face is 15 °~45 °.It is highly preferred that may also be configured to 15 °~30 °.Under optimized angle, work as sealing fluid
Uniformly filling to outer tube plug into section 31 internal perisporium and interpolation pipe plug into section 21 periphery wall between when, i.e., just it is substantially all
Solidify and no longer flows.In other words, setting preferred angle is conducive to shorten the waiting curing time of sealing fluid, and can protect
The uniformity and compactness for demonstrate,proving its filling, to guarantee the lower leak rate of pipeline connection.
Alternatively, by sealing fluid 4 filling to outer tube plug into section 31 internal perisporium and interpolation pipe plug into section 21 periphery wall it
Between include:
Coupling ring 1 is being moved along pipeline and is being tightly placed in front of outer tube plugs into section 31, sealing fluid 4 is being directly injected into outer
Casing plug into section 31 internal perisporium and interpolation pipe plug into section 21 periphery wall between fit clearance in.In other words, can also including
After outer tube is mutually inserted, sealing fluid is directly injected into its fit clearance, and in the present embodiment can also be to compressor circuit 3
Inclination upwards is carried out to put.
Under normal conditions, compressor circuit 3 is copper pipeline, and preferably using Y2 rank and the durometer level of HV >=110
Other copper pipe, device pipeline 2 are the steel pipeline equipped with external coating (usually Aluminum-zinc coating).And sealing fluid generally comprises methyl
Acrylate ingredient, be one pack system anaerobic adhesive liquid, can remove pipeline surface greasy dirt and shallower gully, pipeline can be solved
The situation for the magnitude of interference deficiency that finished surface may cause due to shadow scratch can be formed under oxygen-free environment with metal surface
Dimerization solid can reach splendid sealing and shockproof effect by being used cooperatively with coupling ring 1.However depositing due to external coating
So that the bonding effect between steel pipeline and sealing fluid is poor, therefore to solve this technical problem, assembly method can also be wrapped
It includes:
Before injecting sealing fluid 4, removal interpolation pipe plug into the external coating in section 21 and to removal external coating after interpolation
Pipe plug into section 21 carry out pre-add heat treatment.In this way, can solve due to sealing fluid curing time is too long and what is be easy to cause lets out
Leakage problem, and thoroughly solve the problems, such as that the copper pipeline of compressor and the steel pipeline in device pipeline 2 can not seal, thus greatly
The big leak rate for reducing pipeline connection.
Hydraulic tongs 5 can be used to elapse coupling ring 1 in the above method to simplify operation referring to Fig. 2.Specifically, will join
Ring 1 is connect to be set on device pipeline 2 to be connected, and by the interpolation pipe of the front of device pipeline 2 plug into section 21 inserting to compress
The outer tube of the front of machine pipeline 3 plug into section 31 lumen in after, so that the left end pawl arm of hydraulic tongs 5 is clamped compressor circuit
