The utility model provides an air conditioner piping 10-1, the unable problem that is suitable for of traditional crossover sub has the circumstances that imperial system series pipeline and metric system series pipeline were used with to among the air conditioning equipment among the prior art. Fig. 1 and 2 are schematic structural views of a first embodiment of an air-conditioning pipe 10-1. As shown in the figure, the air-conditioning tubing 10-1 comprises a first tube orifice 12-1 and a second tube orifice 16-1, wherein the first tube orifice 12-1 is provided with a first flaring orifice 14-1 matched with a first pipeline, and the second tube orifice 16-1 is provided with a second flaring orifice 18-1 matched with the first pipeline. The first and second flares 14-1 and 18-1 are each bell-mouth shaped. When it is desired to install in the field, both first and second flares 14-1 and 18-1 may be directly butted against a first pipe (not shown).

The pipe body 20-1 of the air conditioning pipe 10-1 extends linearly as shown by L in the figure. The first pipe orifice 12-1 and the second pipe orifice 16-1 are respectively formed at two ends of the pipe distribution body 20-1, namely, the pipe distribution body 20-1 is positioned between the first pipe orifice 12-1 and the second pipe orifice 16-1, the first flaring 14-1 is formed at one end of the pipe distribution body 20-1 through expansion, and the second flaring 18-1 is formed at the other end of the pipe distribution body 20-1 through expansion.

The pipe body 20-1 includes at least a first cuttable pipe section 24-1 and a second cuttable pipe section 22-1. The first cuttable pipe segment 24-1 is mated with a first pipe flaring device to operatively form a first interface at one end thereof adapted to the first pipe in a severed state. The second cuttable pipe segment 22-1 is then mated with a second pipe flaring device operable to form a second interface at one end thereof that is adapted to a second pipe in a severed condition. The second cuttable pipe section 22-1 has an outer diameter different from the outer diameter of the first cuttable pipe section 24-1. In this embodiment, the outer diameter of the second cuttable tube segment 22-1 is less than the outer diameter of the first cuttable tube segment 24-1.

In a split air conditioner or a multi-split air conditioner, the situation that the English system pipeline and the metric system pipeline are used together is met, the former is often used in an export machine type, and the latter is often used in a local machine type; however, for reasons of uniform models and mass production, the outlet model and the native model are compatible, for example, the outdoor unit of the outlet model is adapted to the indoor unit of the native model, in this case, the outdoor unit pipe reserved for the outdoor unit is english pipe, and the indoor unit pipe reserved for the indoor unit is metric pipe, that is, the metric pipe and the english pipe are mixed. For pipes of the same nominal diameter, the outer diameter of a metric pipe is smaller and the outer diameter of an english pipe is larger. The air conditioning pipe 10-1 requires fluid connection of an outdoor unit pipe and an indoor unit pipe to ensure a stable flow of a refrigerant therein, and requires an operator to extend and cut the pipe in the field due to different field installation environments of each air conditioning device, so that the first and second flare portions 14-1 and 18-1 formed at both ends of the pipe body 20-1 cannot be directly flared but require secondary pipe expansion in the field. During secondary pipe expansion, when a British system pipeline (an outdoor unit pipeline or an indoor unit pipeline) is connected, the pipe needs to be matched with British system pipeline expanding equipment, namely the pipeline is fixed on the British system pipeline expanding equipment for secondary pipe expansion. When a metric pipeline (an outdoor unit pipeline or an indoor unit pipeline) is connected, the device needs to be matched with a metric pipeline flaring device, namely, the pipeline is fixed on the metric pipeline flaring device to carry out secondary pipe expanding. As described above, for the same nominal diameter pipe, the outer diameter of the metric pipe is smaller and the outer diameter of the english pipe is larger; in order to realize the pipeline fixation, the British system pipeline flaring device and the metric system pipeline flaring device are respectively designed corresponding to the standard outer diameter of the British system pipeline and the standard outer diameter of the metric system pipeline, and cannot be used in a mixed way.

To address this, the air conditioning pipe 10-1 shown in fig. 1 and 2 is specially designed with a first cuttable pipe section 24-1 and a second cuttable pipe section 22-1, the first cuttable pipe section 24-1 has an outer diameter larger than that of the second cuttable pipe section 22-1, the first cuttable pipe section 24-1 can be matched with a first pipe flaring device, i.e., a british pipe flaring device, to operatively form a first interface adapted to a first pipe (e.g., a british pipe) at one end thereof in a cut-off state, and to realize further connection in the cut-off state. Correspondingly, the second cuttable pipe section 22-1 can be matched with a second pipe flaring device, i.e. with a metric pipe flaring device, to form at one end thereof an adapted, trumpet-like second interface to a second pipe (e.g. metric pipe) in a cut-off state, in which a further connection is achieved.

In actual operation, one of the first flared opening 14-1, the second flared opening 18-1, the first port and the second port is fluidly connected to outdoor unit piping, and the other one is fluidly connected to indoor unit piping. Thus, as shown in fig. 1 and fig. 2, the same air-conditioning piping 10-1 can selectively realize connection between the english piping and the english piping, between the english piping and the metric piping, between the metric piping and the english piping, and between the metric piping and the metric piping, and can perform secondary flaring by using the first piping flaring device (e.g., the english piping flaring device) or the second piping flaring device (e.g., the metric piping flaring device) while meeting the requirement of field installation length, so that the adaptability and flexibility of the air-conditioning piping 10-1 are greatly improved, and meanwhile, other parts do not need to be added, and the leakage risk of the air-conditioning piping 10-1 is reduced. The air conditioning tubing 10-1 may also be modularly connected to each other to extend the overall length of the air conditioning tubing.

In this embodiment, the first pipe represents a pipe expressed in english, and its nominal diameter may be selected according to english standards without further specific limitations. The second line represents a pipe expressed in metric system, the nominal diameter of which can be chosen according to metric standards without further limitation. In other embodiments of the present invention, the first conduit may also represent a pipe expressed in terms of a metric system, the nominal diameter of which is not further specifically limited; the second line represents a pipe expressed in english with its nominal diameter not being further limited.

As shown in fig. 5, the outdoor or indoor piping may extend into the first coupling nut 28-1 in the direction D1 or D2, and the first nozzle 12-1 may extend into the first coupling nut 28-1 in the opposite direction. The internal thread of the first coupling nut 28-1 is screw-coupled to the external thread of the outside of the first nozzle 12-1 and the external thread formed on the outside of the outdoor unit pipe or the indoor unit pipe, respectively, and the first coupling nut 28-1 is screw-fixed to the outside of the first flare 14-1. The first connecting nut 28-1 is sleeved outside the first connecting pipe section 26-1 in a non-mounting state, is not easy to lose, and has the advantages of easiness in mounting and convenience in operation. The flaring connection can ensure that the diameter of the connection part is not reduced, the flow of the pipeline is not influenced, and the temperature fluctuation of the refrigerant is avoided.

At the other end, the air conditioning pipe 10-1 includes a second connection pipe section 32-1, and the second nozzle 16-1 is formed at one end of the second connection pipe section 32-1. As shown in fig. 1, 2 and 5, the first coupling nuts 28-1 of the air conditioning pipe 10-1 are provided in pairs, and the other first coupling nut 28-1 is fitted around the outside of the second coupling pipe section 32-1. When the second enlarged end 18-1 is fluidly connected to one of the outdoor unit pipe or the indoor unit pipe, the first coupling nut 28-1 is threadedly fixed to the outside of the second enlarged end 18-1.

Similarly, the first coupling nut 28-1 is threadedly fixed to the outside of the first port when the first port is fluidly coupled to one of the outdoor unit pipe or the indoor unit pipe. As shown in fig. 5, the outdoor or indoor piping can extend into the first coupling nut 28-1 along the direction D1 or D2, and correspondingly, the first interface can extend into the first coupling nut 28-1 along the opposite direction, so as to implement flared piping connection.

As shown in fig. 6, the outdoor unit pipe or the indoor unit pipe may extend into the second coupling nut 30-1 along a direction D3 or D4 in the drawing, and correspondingly, the second port may extend into the second coupling nut 30-1 along another opposite direction, so as to implement flared pipe connection.

As shown in fig. 1 and 2, the first cuttable pipe segment 24-1 is formed at the center of the pipe body 20-1 and extends in the same direction as the extending direction of the pipe body 20-1. The second cuttable pipe sections 22-1 are symmetrically arranged on two sides of the first cuttable pipe section 24-1, and the length of the second cuttable pipe section 22-1 is larger than that of the first cuttable pipe section 24-1.
