Abstract
The utility model provides an internally-connected pipeline of a reservoir. The internally-connected pipeline of the reservoir reduces the overall cost and is good in use effect, not prone to breakage, safe, and reliable. The internally-connected pipeline of the reservoir comprises a pipeline body. The pipeline body comprises an outlet copper pipe and an inner delivery iron pipe, wherein the outlet copper pipe and the inner delivery iron pipe are welded together. The edge of a bottom pipe opening of the outlet copper pipe is of a wave shape. The edge of a top pipe opening of the inner delivery iron pipe is of a wave shape matched with the wave shape of the edge of the bottom pipe opening of the outlet copper pipe. A widened horn opening is arranged outside the bottom of the outlet copper pipe. The inner delivery iron pipe is sleeved with the horn opening, and the horn opening is fixed through brazing. According to the structure, an independent copper pipe of the prior art is replaced by the connecting pipes arranged at the two ends; the edge of each pipe is of the wave shape, so that the area of the welding portion of a connection joint is increased, and the welding strength is improved; due to the arrangement of the horn opening, on one hand, one welding position is added, and on the other hand, matching between the curved faces of the two pipes is facilitated.
Description
Technical field
The utility model relates to a kind of pipeline configuration, specially refers to a kind of reservoir inner connecting tube road.
Background technology
Reservoir is to be fitted in A/C evaporator and compressor suction duct position, is to prevent that liquid refrigerant from flowing into compressor and producing the guard block of liquid hammer.In air-conditioning system running, cannot guarantee that cold-producing medium can all vaporize completely; Namely from evaporimeter cold-producing medium out, having liquid cold-producing medium enters in reservoir, owing to there is no the liquid refrigerant of vaporization because itself is than gas weight, at the bottom of can directly putting off reservoir cylinder, the cold-producing medium of vaporization is entered in compressor by the outlet of reservoir, thereby has prevented that compressor inhalant liquid cryogen from causing liquid hammer.The long-term running of compressor; its inside has certain lubricating oil and discharges with the cold-producing medium of vaporization; by pipeline, can enter in liquid storage cylinder; owing to being welded on the escape pipe of liquid storage cylinder bottom, there is processing " spill port "; so be deposited in the lubricating oil of cylinder body bottom, by the suction of compressor, make power; return the escape pipe of reservoir not only but also enter in compressor, thereby compressor is played again to lubrication protection effect.As can be seen here, the pipeline of reservoir is the pith of guaranteeing that whole system runs well.According to the design of prior art, several key structures of reservoir all take into full account, and technology is quite ripe.But in prior art, still have some problems, i.e. the high cost of pipeline, once and piping failure, keep in repair also very inconvenient.
In prior art, also there is the mode that welds together to reduce costs by copper pipe and iron pipe.But such welding manner, has a problem, be exactly weld easily fracture after long-time use, therefore, we also need to manage to improve the intensity of junction.
Utility model content
The utility model proposes a kind of reservoir inner connecting tube road, reduce the holistic cost of pipeline, result of use is good, is difficult for disconnecting simultaneously, safe and reliable.
For reaching described object, the utility model relates to a kind of reservoir inner connecting tube road, comprise pipe main body, described pipe main body comprises the copper outlet conduit that welds together and the inner duct of irony, mouth of pipe edge, described copper outlet conduit bottom is waveform, and the described inner duct top mouth of pipe is the waveform matching, and outlet conduit bottom outside is provided with the horn mouth of widening, described horn mouth is socketed in the inner duct outside of irony, by Welding, fixes.
Preferably, the waveform at mouth of pipe edge, described copper outlet conduit bottom has a crest and a trough.Such structure has improved the bonding area of junction, but it is too complicated to be unlikely to again structure, has reduced production cost.
Preferably, described pipeline body outside is provided with protective sleeve, and described protective sleeve is connected on reservoir opening part by carbon dioxide arc welding.Protective sleeve is to the pipeline protection in outside
Preferably, described copper outlet conduit adopts TP2 copper to become.
Preferably, the inner duct of described irony is by adopting the bodied ferric sulfate material of Q195 iron to make.
By such structure, the utility model replaces the independent copper pipe of prior art by two ends tube connector.The area that waveform improves seam weld is set at pipeline edge, improves weld strength.Horn mouth is set simultaneously, on the one hand more welding positions, the coupling of two canal surfaces while being convenient to weld on the other hand.
Accompanying drawing explanation
Fig. 1 is the structure for amplifying schematic diagram of the pipeline junction in a kind of reservoir inner connecting tube of the utility model road.
The specific embodiment:
As shown in Figure 1, a kind of reservoir inner connecting tube of the utility model road, comprise pipe main body, described pipe main body comprises the copper outlet conduit 1 that welds together and the inner duct 2 of irony, described copper outlet conduit 1 mouth of pipe edge, bottom is waveform, and the described inner duct 2 top mouths of pipe are the waveform matching, and outlet conduit 1 bottom outside is provided with the horn mouth 3 of widening, described horn mouth 3 is socketed in inner duct 2 outsides of irony, by Welding, fixes.The waveform at described copper outlet conduit 1 mouth of pipe edge, bottom has a crest and a trough.Described pipeline body outside is provided with protective sleeve 4, and described protective sleeve 4 is connected on reservoir opening part by carbon dioxide arc welding.Described copper outlet conduit 1 adopts TP2 copper to become.The inner duct 2 of described irony is by adopting the bodied ferric sulfate material of Q195 iron to make.
During installation, inner duct 2 is inserted in the horn mouth 3 of outlet conduit 1 bottom.Then rotate inner duct 2 until both mouth of pipe edges fit like a glove.Now can both be welded together from mouth of pipe inside.Again horn mouth 3 and inner duct 2 outsides are welded together simultaneously.Like this, between inner duct 2 and outlet conduit 1, by corrugated joint face, improved bonding area.For generally speaking, the mode of two sections of welding has also been strengthened overall construction intensity greatly.
During use, the utility model has replaced the structure of a common copper pipe in prior art.Reduce production cost, but do not affected result of use at all.Whole service life improves on the contrary, and maintenance is also convenient.
The foregoing is only specific embodiment of the utility model, but architectural feature of the present utility model is not limited to this, any those skilled in the art is in field of the present utility model, and the variation of doing or modification are all encompassed among the scope of the claims of the present utility model.
