Abstract
The utility model provides a liquid accumulator pipeline which is less in total cost of the pipeline, good in use effect, convenient to maintain, safe and reliable in overall use and less prone to damage. The liquid accumulator pipeline comprises a protective jacket arranged at a position of an incoming and outgoing pipeline opening of a liquid accumulator, the projective jacket is sleeved on the outer side of a pipeline body which comprises an outer connecting pipe and an inner delivering pipe, a widened sleeve opening is formed in a joint of the inner delivering pipe, and the outer connecting pipe is welded to the inner side of the widened sleeve opening. By the structure that the connecting pipes at two ends of the pipeline body take the place of an independent copper pipe in the prior art, overall cost of the pipeline is lowered on the one hand, and on the other hand, the outer connecting pipe does not need to be demounted during maintenance and the inner delivery pipe can be directly replaced to complete the maintenance of an internal pipeline, so that convenience in maintenance is improved.
Description
Technical field
The utility model relates to a kind of reservoir, specially refers to a kind of reservoir pipeline.
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.
Utility model content
The utility model proposes reservoir pipeline, reduce the holistic cost of pipeline, result of use is good, and is convenient to safeguard.Pipeline integral body is safe and reliable, not fragile.
For reaching described object; the utility model relates to a kind of reservoir pipeline; the protective sleeve that comprises the turnover mouth of pipe place that is arranged on reservoir; described protective sleeve is set in pipe main body outside; described pipe main body comprises extension tube attached and interior defeated pipe; described Nei Shuguan junction is provided with widens running-on, and described extension tube attached is welded on widens running-on inner side.
Preferably, described protective sleeve inserts the turnover nozzle position of reservoir and fixes, and protective sleeve is identical with the length in outside in reservoir inner side.Such mounting means has been guaranteed the stability of protective sleeve self.
Preferably, described extension tube attached is copper pipe, and described interior defeated pipe is iron pipe.Copper pipe can be guaranteed outside heat conductivility for extension tube attached.Iron pipe is used for interior defeated pipe to reduce costs.
Preferably, described protective sleeve covers the junction between extension tube attached and interior defeated pipe.Such structure gives the protection of one of junction.
By such structure, the utility model replaces the independent copper pipe of prior art by two ends tube connector.Not only reduced pipeline holistic cost, when maintenance, will extension tube attached not pull down simultaneously, directly changed inner connecting tube and just can complete the maintenance of internal pipeline.Improved like this convenience of maintenance.
Accompanying drawing explanation
Fig. 1 is the structure for amplifying schematic diagram of the pipeline junction of a kind of reservoir pipeline of the utility model.
The specific embodiment:
As shown in Figure 1; the utility model reservoir pipeline; the protective sleeve 1 that comprises the turnover mouth of pipe place that is arranged on reservoir 4; described protective sleeve 1 is set in pipe main body outside; described pipe main body comprises extension tube attached 2 and interior defeated pipe 3; described interior defeated pipe 3 is provided with and widens running-on in junction, and described extension tube attached 2 is welded on widens running-on inner side.The turnover nozzle position that described protective sleeve 1 inserts reservoir 4 is fixed, and protective sleeve 1 is identical in the length in reservoir 4 inner sides and outside.Described extension tube attached 2 is copper pipe, and described interior defeated pipe 3 is iron pipe.Described protective sleeve 1 covers the junction between extension tube attached 2 and interior defeated pipe 3.
The utility model occupation mode is the same with prior art, is direct use equally.Very convenient, and be copper pipe by extension tube attached 2, described interior defeated pipe 3 is iron pipe.Different saw lumbers have reduced cost, but not to bate a jot of one's demands few result of use.And effectively protect by the pipeline of protective sleeve 1 structure Neng Dui junction.
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.
