Abstract
The utility model relates to a connecting pipe for an indoor machine and an outdoor machine of an air conditioner. The utility model is characterized in that the utility model is formed by the way that both ends of a pure aluminium pipe section are respectively welded with a copper pipe joint. By considering the antisepsis requirement of the pure aluminium pipe section and copper aluminium connecting points, except for the positions near two ports of the surface of the whole connecting pipe, the positions which comprises the aluminium pipe section, the copper pipe joint and a welded gap which is between the aluminium pipe section and the copper pipe joint are coated with plastic layers which have an insulation and antiseptic function. Thereby, the utility model with the structure has the advantages of cost reduction, copper material consumption reduction, smooth and beautiful appearance of the connecting pipe, and operation requirement conformity. The technology of the utility model not only can be used for an air conditioner but also can be used for other copper pipe connecting applications which require that the joint has the advantages of high fastness, good sealability and manufacturing cost reduction.
Description
Technical field
The utility model relates to a kind of connecting tube, specifically a kind of tube connector that is used for transmitting between the inside and outside machine of air-conditioner refrigerant.
Background technology
The inside and outside machine of existing air-conditioner all adopts long copper pipe to link to each other, therefore, a large amount of uses the noble metal copper of shortage of resources, this also is to cause one of high reason of air-conditioner cost.
The solder technology of existing copper aluminium electric resistance welding has been improved the difficult problem solved the copper Al pipe butt welding, for the utility model provides the reliable technique basis, produces the adapter that is used for machine inside and outside the air-conditioner device based on aluminum pipe brand-new for this reason.
Summary of the invention
The objective of the invention is to overcome the deficiency of prior art, a kind of adapter that is used for the inside and outside machine of air-conditioner is provided.
Basic structure of the present utility model is to adopt the plug-in type welding manner at long pure aluminum tube (section) two ends, and each welds a bit of copper pipe and forms.
Consider the anticorrosion needs of the anticorrosion of fine aluminium pipeline section and copper aluminium contact, near the surface of whole tube connector (comprise aluminum pipe section and copper pipe joint and weld seam therebetween, the two-port except) can be applied the protective layer of insulation and antisepsis again---mould layer.
Description of drawings
Fig. 1, basic structure schematic diagram of the present utility model.
The specific embodiment
As Fig. 1 technical characterictic of the present utility model is respectively to be welded with copper pipe joint 2 to form at fine aluminium pipeline section 1 two ends; Further for for the purpose of anticorrosion, layer 3 is moulded on the surface outside above-mentioned fine aluminium pipeline section 1 and copper pipe joint 2 and weld seam A therebetween, as surface plastic spraying, spray paint or overlap heat-shrink tube as protective layer.
For easy for installation, be provided with copper nut (figure slightly) usually at copper pipe joint 2 two ends by prior art, so that link to each other with the valve or the joint of air conditioner indoor and outdoor machine.
The utility model of constructing thus not only reduces cost, and it is smooth attractive in appearance to reduce copper material consumption and its tube connector, meets instructions for use.This utility model technology not only can be used for air-conditioner, also can be used for other copper pipes that require joint fastness height, good airproof performance, reduction manufacturing cost and connect application.
Claims (2)
1, a kind of adapter that is used for the inside and outside machine of air-conditioner is characterized in that respectively being welded with copper pipe joint (2) at fine aluminium pipeline section (1) two ends forms.
2, the adapter that is used for the inside and outside machine of air-conditioner as claimed in claim 1 is characterized in that layer (3) is moulded on the surface outside above-mentioned fine aluminium pipeline section (1) and copper pipe joint (2) and weld seam therebetween.
