Abstract
The utility model discloses the technical field of an air conditioner, in particular to a connecting pipe for an indoor unit and an outdoor unit, which comprises a throttling sleeve (2) and pipelines (3) which are respectively connected on both ends of the throttling sleeve (2), wherein one pipeline is connected with a two-way valve of the outdoor unit, the other pipeline is connected with an auxiliary pipeline of the indoor unit, and both ends of the throttling sleeve (2) are provided with filter screens (1). The connecting pipe can enable the different indoor units to be matched with the different outdoor units, the structure is simple and the cost is lower.
Description
Technical field
The utility model relates to the air-conditioner technical field, relates in particular to a kind of indoor and outdoor machine tube connector.
Background technology
Domestic air conditioner is to use capillary as restricting element basically in the market, and this with the structure of capillary as restricting element, not only manufacture craft is loaded down with trivial details, yielding, be difficult for assembling, simultaneously because solder joint is many, the hidden danger of quality that has secondary refrigerant leakage, and cost height.
Though recently have choke valve and restriction sleeve are applied to the correlation technique of domestic air conditioner as restricting element, still, also do not have the indoor and outdoor machine connecting leg and the air-conditioner thereof of restriction sleeve assembly.
The utility model content
At the shortcoming of prior art, the purpose of this utility model provides a kind of different indoor set can mate mutually with different off-premises stations, and simple in structure, the indoor and outdoor machine tube connector that cost is lower.
For achieving the above object, the technical solution of the utility model is: a kind of indoor and outdoor machine tube connector, it comprises restriction sleeve and is connected to the pipeline at restriction sleeve two ends, wherein a pipeline is connected with the two-port valve of off-premises station, another pipeline is connected with the subsidiary conduit of indoor set, and the two ends of this restriction sleeve are equipped with screen pack.
The outer wall at described restriction sleeve two ends is pressed into an integral body with the inwall of two pipelines, one end respectively; The outer wall of the outer edge surface of described screen pack and pipeline one end is pressed into an integral body.
The external diameter of described pipeline is φ 5mm～φ 30mm, and wall thickness is 0.28mm～1.5mm.
Compared with prior art, the utility model is by restriction sleeve and be connected to the pipeline at restriction sleeve two ends, broken through traditional split-type air conditioner air conditioner indoor machine and off-premises station occupation mode one to one, for regulating the air-conditioner that restricting element just can form new series or model, by selecting the tube connector of band different size restriction sleeve assembly for use, can be so that an indoor set be joined different off-premises stations, identical off-premises station is joined different indoor sets, make that design, production, the after-sale service of air-conditioner are all convenient, and with low cost.
The utility model relatively uses air-conditioner capillaceous, and its off-premises station has been cancelled elements such as capillary, filter, check valve, damping be fast, make with material still less, solder joint still less, structure is simpler, reliability is higher.
In addition, easy to maintenance when the utility model breaks down at restricting element, cost is low.And when using capillary as restricting element, dirty stifled when waiting other faults when occurring, must use special-purpose welding equipment, the tube connector of tape swapping orifice union gets final product and use air-conditioner of the present utility model only to need more.
Description of drawings
Fig. 1 is the structural representation of the utility model indoor and outdoor machine tube connector.
The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
As shown in Figure 1, a kind of indoor and outdoor machine tube connector, it is characterized in that the pipeline 3 that comprises restriction sleeve 2 and be connected to restriction sleeve 2 two ends, wherein a pipeline is connected with the two-port valve of off-premises station, the condensator outlet pipe directly with the linking to each other of two-port valve, another pipeline is connected with the subsidiary conduit of indoor set, and the two ends of this restriction sleeve 2 are equipped with screen pack 1.
The outer wall at described restriction sleeve 2 two ends is pressed into an integral body with the inwall of two pipelines, 3 one ends respectively; The outer wall of the outer edge surface of described screen pack 1 and pipeline 3 one ends is pressed into an integral body.
The described air-conditioner that has the indoor and outdoor machine tube connector of restriction sleeve assembly, during the air-conditioner refrigerating operaton, refrigerant directly to two-port valve, through having the indoor and outdoor machine tube connector of restriction sleeve assembly, arrives indoor set by off-premises station heat exchanger exit pipe again.During the air conditioner heat-production operation, refrigerant to the indoor and outdoor machine tube connector that has the restriction sleeve assembly, arrives off-premises station through indoor set by the off-premises station triple valve again.
The described indoor and outdoor machine tube connector that has restriction sleeve can be from 2 meters to 50 meters according to different air-conditioner length.The external diameter of described pipeline 3 is φ 5mm～φ 30mm, and wall thickness is 0.28mm～1.5mm.
Different indoor sets, different off-premises stations and contain the various combination of the indoor and outdoor machine tube connector of restriction sleeve assembly can form the air-conditioner of different series.
Claims (4)
1, a kind of indoor and outdoor machine tube connector, it is characterized in that the pipeline (3) that comprises restriction sleeve (2) and be connected to restriction sleeve (2) two ends, wherein a pipeline is connected with the two-port valve of off-premises station, another pipeline is connected with the subsidiary conduit of indoor set, and the two ends of this restriction sleeve (2) are equipped with screen pack (1).
2, indoor and outdoor machine tube connector according to claim 1 is characterized in that: the outer wall at described restriction sleeve (2) two ends is pressed into an integral body with the inwall of two pipelines (3) one ends respectively.
