Specific embodiment
As shown in Figure 1 and Figure 2, the invention proposes a kind of air-conditioning duct structures, comprising: first pipe 1, second pipe 2,
Valving 3 and first switch valve 4, first pipe 1 and second pipe 2 are connected between the indoor unit of air-conditioning and outdoor unit, the
One pipeline 1 is the minor valve 7 that inlet tube connects air-conditioner outdoor unit, and second pipe 2 is the big valve that circulation pipe connects air-conditioner outdoor unit
Door 8, for the refrigerant circulation between indoor unit and outdoor unit, the position in first pipe 1 and second pipe 2 convenient for operation is all provided with
There is valving 3, can really be evacuated or be added the maintenance operation of refrigerant to air-conditioning directly on valving 3, wherein first opens
First pipe 1 is arranged in for pass valve 4 and second pipe 2 is located on valving 3 to one section between indoor unit, can when vacuumizing
The pipeline for being connected to indoor unit is closed, indoor unit is closed, avoids indoor unit after maintenance from entering air, needs with a large amount of refrigerants
It rinses, pollutes environment.
In the present invention, there are three connectivity ports for the tool of valving 3, are equal to the large and small valve being arranged on outdoor unit, infuse fluorine
Mouth 31 is disposed therein on a connectivity port, can carry out note fluorine to air-conditioning by fluorinfused nozzle 31, valving 3 is connected to air-conditioning
The connectivity port of indoor unit is equipped with union nut, and first pipe 1 and second pipe 2 pass through union nut valve corresponding with two
Device 3 connects, and can close two first switch valves 4 when vacuumizing, then unscrew the union nut of two valvings 3, will take out
Vacuum plant is fastened after docking with the connectivity port of valving 3 by union nut, can be taken out to air-conditioner outdoor unit
Vacuum.
It is additionally provided with sealed core valve 33 on valving 3, three connectivity ports of valving 3 can be cut-off, seals
The middle part of valving 3 is arranged in core valve 33, after sealed valve core 33 is depressed, can interrupt pipeline and fluorinfused nozzle.
The invention also includes multiple connection components 6 being arranged in first pipe 1 and second pipe 2, wherein first pipe
