Abstract
The utility model relates to a refrigeration system pipeline for a movable air conditioner, which comprises a compressor, a condenser, a throttling device and an evaporator that are circularly connected by pipelines, wherein a maintenance port is formed on the pipeline between the compressor and the condenser. With the adoption of the maintenance port on the refrigeration system pipeline, the later overhaul work such as air conditioner pipeline moving can be simplified greatly, and the maintenance cost can be lowered. The maintenance port of the refrigeration system pipeline is easy and simple to operate and simple in structure. The refrigeration system pipeline can be used for a pipeline system of a dehumidifier and the like, and has an obvious effect.
Description
Technical field
The utility model relates to a kind of pipeline, particularly a kind of refrigeration system pipeline of mobile air conditioner.
Background technology
Existing mobile air conditioner, its structure generally comprises housing, motor and wind wheel, and be arranged in the housing and the compressor, condenser, throttling arrangement and the evaporimeter that circulate and connect successively, be designed with a process duct at the pipeline that is formed by compressor, condenser, throttling arrangement and evaporimeter, in the production process, by the process duct charging refrigerant, filled behind the cold-producing medium welding of the technique mouth of pipe has been sealed, prevent that leakage of refrigerant is out.Like this when the refrigeration system of air-conditioning has fault, need to weld process duct get off, again weld a new process duct, in the time of special so outside maintenance, need to have in advance new process duct, increase the service material cost, and Rewelding may result in blockage easily like this, reduced maintenance efficiency, filled or to append cold-producing medium very inconvenient.
The utility model content
It is ingenious that the purpose of this utility model provides a kind of design, is convenient to the refrigeration system pipeline of the mobile air conditioner of later stage maintenance.
The technical scheme that realizes the utility model purpose is: the utility model comprises by the compressor of pipeline successively circular linkage, condenser, throttling arrangement and evaporimeter; Be provided with the maintenance port on the described pipeline.
Above-mentioned maintenance port is arranged on the pipeline between compressor and the condenser.
Above-mentioned maintenance port comprises tube connector, nipple, valve inside and bonnet; One end of described tube connector is connected with pipeline and communicates, and the other end is connected with nipple and communicates; The inside of described nipple is provided with valve inside, and the external screw-thread of nipple is connected with bonnet.
Above-mentioned maintenance port comprises tube connector, logical valve union, valve rod and bonnet; Described logical valve union has connection pipe end, control pipe end and the maintenance pipe end that communicates; One end of described tube connector is connected with pipeline and communicates, and the pipe end that is connected of the other end and logical valve union connects and communicates; The inside of described control pipe end is provided with valve rod; The external screw-thread of described control pipe end and maintenance pipe end is connected with bonnet.
The center, top of described valve rod offers hexagon ring, and one week of tip exterior offers seal groove, is arranged with sealing ring in the seal groove; The top, top of described valve rod is provided with back-up ring.
The utlity model has positive effect: the later stage service work that the maintenance port on (1) the utility model can greatly easy mobile air conditioner pipeline etc., and can reduce maintenance cost; (2) maintenance port operation of the present utility model is easy, simple in structure.
