Abstract
A connecting pipeline for indoor and outdoor set of home air conditioning system, which is used for the medium circulation between the indoor and the outdoor sets. The existing technologies all take the red copper pipe as the connecting pipe of the indoor and the outdoor sets, therefore a high production cost is brought about by the scarce red copper; The utility model is characterized in that two connecting tubes made of copper or steel are respectively connected with two ends of a stainless steel ripple pipe, and horn mouth seal faces are arranged at the outer end of the connecting tubes, moreover the threaded pipe connectors made of copper or steel, which are matched with the horn mouth seal faces, are covered on the connecting tubes. The utility model adopts the stainless steel tubing to carry through a special machining forming so as to obtain the flexibility and the pliability needed by the materials, and then to improve the durability, therefore a reliable connection between the indoor and the outdoor sets can be ensured finally; thanks to adopt the connection solution of the stainless steel tubing, so the cost will be reduced more than 50%; owing to adopt the stainless steel material, the compression resistance and the resistance to corrosion of the steel tubing can be improved greatly, at the same time, because of the synthetic processing technology production is adopted by the stainless steel material, and therefore the material source is more comprehensive than before.
Description
Technical field
The utility model is the connecting pipeline between the unit of a kind of domestic air-conditioning system indoor and outdoor, is used for the circulation of medium between the unit of indoor and outdoor.
Background technique
Connecting pipeline between the unit of domestic air-conditioning system indoor and outdoor main rising in refrigeration system depressed the refrigeration agent in the outdoor unit in the heat exchanger that is delivered into indoor set in adding of compressor, by heat exchange realization refrigeration or after heating, be back to the compressor of outdoor unit again by connecting tube, thereby finish the circulation of refrigeration agent.The material of connecting pipeline mainly is must be reliable with refrigeration agent compatibility and tie point sealing under pressure, anti-outdoor rugged environment.Owing to be subjected to the uncertainty of the mounting point of chamber, inside and outside machine, connecting pipeline must have certain elasticity and pliability simultaneously, so that guarantee when making things convenient for bending forming when air conditioner is installed that the pipe deformation rate is little, does not influence the flow of refrigeration agent.Present general mode is for adopting copper soft attitude coil pipe of thin-walled or the soft attitude pipe of the copper mosquito-repellent incense shape of the thin-walled connecting pipeline (referring to Fig. 1) as unit inside and outside the air conditioning chamber, because copper material is limited valuable non-ferrous metal, cost of material is high.
The model utility content
The technical assignment of the technical problems to be solved in the utility model and proposition is the defective that will overcome the manufactured materials costliness of existing connecting pipeline existence, and a kind of connecting pipeline between the domestic air-conditioning system indoor and outdoor unit that replaces existing copper material on the reliable connection basis between the inside and outside unit in the original air conditioning chamber of assurance with new material is provided.For this reason, the utility model is by the following technical solutions:
Connecting pipeline between the unit of a kind of domestic air-conditioning system indoor and outdoor, it is characterized in that: respectively connect copper or steel connecting tube at the two ends of corrugated stainless steel tubing, the outer end of described connecting tube has the horn mouth sealing surface, and is with copper or the steel screwed pipe joint that matches with described horn mouth sealing surface on described connecting tube.
The material of described corrugated stainless steel tubing is SUS304, SUS303, SUS302,1Cr18Ni9,1Cr18Ni9Ti, 0Cr18Ni9 or 1Cr17Ni8.Such material has intensity and workability preferably, and for making the industry common used material.
The ripple of described corrugated stainless steel tubing shape in the shape of a spiral distributes.After being processed into the shape of threads bellows, help flowing of refrigeration agent.And the stainless steel pipe that is difficult to bending is originally become can be arbitrarily crooked, reaches the bending performance that is had with soft attitude copper tube.
The ripple cross section of described corrugated stainless steel tubing is semicircle shape, rectangle, trapezoidal or triangle.Semicircle bellows inwall resistance is little, reduces refrigerant pressure loss.Rectangle, trapezoidal, triangle ripple pipe processing mold equipment is simpler relatively, manufacturing efficiency is higher.
The ripple continuous distributed of described corrugated stainless steel tubing.The ripple of continuous distributed can make tubing have minimum bending radius.
The ripple of described corrugated stainless steel tubing is interrupted distribution.Under can adopting, can reduce labor content, reduce fabricating cost than the occasion of macrobending radius.
Described copper or steel connecting tube are connected by soldering or riveted joint with corrugated stainless steel tubing.Soldering and riveting technology are all having ripe processing technology now, can guarantee the effective intensity and the sealing of junction surface.
The end that described copper or steel connecting tube are connected with corrugated stainless steel tubing is enlarging, reducing or latus rectum structure.According to the different requirements of system to the pipeline latus rectum, under the prerequisite of the required latus rectum of assurance system, can adopt less caliber material to reduce by enlarging and take over cost of material, can improve the adapter passing rate of processing by reducing reduces production costs, by adopting the exhaust pipe passage structure can reduce the manufacturing procedure of pipe end, reduce cost.
The technical solution of the utility model is compared with the connecting pipeline of prior art, and it to meet the requirements of elasticity and pliability, improves serviceability by stainless steel pipe is carried out special shaping, and guarantees the reliable connection between the inside and outside unit in air conditioning chamber; Because of the replacement of material, reduce cost of material, adopt the connectivity scenario of the stainless steel pipe in the utility model cost-saved more than 50%; Make tubing have stronger compression resistance ability and anti-corrosion capacity after adopting stainless steel material, stainless steel material is synthetic processing technology production simultaneously, and the source of material is more extensive.
