Air-conditioning is divided into single cold air-conditioning and air conditioner for both cooling and heating, working principle be it is the same, generally used mostly before air-conditioning
Refrigerant be freon.The characteristic of freon is: when becoming liquid from gaseous state, discharging a large amount of heat.And changed by liquid
When for gaseous state, a large amount of heat can be absorbed.(i.e. first endothermic gasification re-liquefied heat release) air-conditioning be exactly accordingly principle and design.
Gaseous refrigerant compression is the gaseous refrigerant of high temperature and pressure by compressor, is then delivered to condenser (outdoor unit)
Become the liquid refrigerant of normal temperature high voltage after heat dissipation, so what outdoor unit produced by boasting is hot wind.Then capillary is arrived, into evaporation
Device (indoor unit), since refrigerant increases suddenly from space after capillary arrival evaporator, pressure reduces, and the refrigerant of liquid is just
It can vaporize, become the refrigerant of gaseous state low temperature, to absorb a large amount of heat, evaporator will turn cold, and the fan of indoor unit will
Indoor air is blown over from evaporator, so what indoor unit produced by boasting is exactly cold wind；Vapor in air encounters cold steaming
The reason of will condensing into water droplet after hair device, spill out along water pipe, can be discharged here it is air-conditioning.
Pipeline must be connected between condenser and evaporator just can be carried out energy exchange, and because of installation requirements, pipeline is not
One, mostly use greatly spliced, and the pipe diameter of condenser and evaporator is not necessarily identical.It is used in connecting pipe
Connector connects non-because to connect the pipeline on both sides simultaneously, and pipeline is metal again, does not have flexibility
Normal inconvenience.

Internal screw thread 1-4, the other end of nut 1 are sodium rim of the mouth 1-5, are lined with gasket 1-6 inside the 1-5 of sodium rim of the mouth；The double end docking
Core 2 includes connector 2-1, attachment device 2-2, sealing ring 2-3, and connector 2-1 points are big connector 2-1-1 and small connector 2-
The one end 1-2, connector 2-1 is connected to attachment device 2-2, and the junction of connector 2-1 and attachment device 2-2 be additionally provided with it is recessed
Slot 2-4, sealing ring 2-3 are caught in groove 2-4；The other end of connector 2-1 is oblique angle design, and the surface of connector 2-1 is provided with
Screw thread 2-5；The upper and lower ends of the attachment device 2-2 all protrude fixed station 2-2-1, and auxiliary device 2-2-2 passes through bayonet lock
2-2-3 is articulated to fixed station 2-2-1；Double end docks core 2 and passes through internal screw thread 1-4 and screw thread 2-5 coupling nut 1.
The connector 2-1 and attachment device 2-2 is an integral structure.
It is that copper screw cap and copper double end dock core that the nut 1, which docks core 2 with double end,.
The size of the big nut 1-1 is 19mm.
The size of the small nut 1-2 is 16mm.
Working principle of the utility model is: utilizing the auxiliary device on double end docking core when connecting pipe, it will be able to not
It in the case where tool, connects by hand, feels not enough can also securely continue lock jail using tool.
After adopting the above technical scheme, the utility model have the beneficial effect that it is easy to connect quickly, it is very useful, do not have to also
Worry in installation process because using tool that can not accurately control dynamics, and overexerts thread damage.
