Abstract

This invention relates to connection pipelines between indoor and outdoor sets of family air-condition system, which sets a copper or a steel connection pipe at either end of a stainless steel ripple pipe, the outer end of which has a seal surface of a horn orifice jacketed with a copper or a steel screw tube joint matched to the sealed surface. This invention applies a special method to process and shape stainless steel tubular materials to reach the required elasticity and pliability and increase durability to secure reliable connection of indoor and outdoor sets.

Description

Connecting pipeline between the unit of domestic air-conditioning system indoor and outdoor
Technical field
The present invention 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.
Summary of the invention
The technical assignment of the technical problem to be solved in the present invention 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 present invention 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, OCr18Ni9 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.
Technological scheme of the present invention 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 among the present invention 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.

Embodiment
Connecting pipeline between domestic air-conditioning system indoor and outdoor unit as shown in Figure 2 is to choose suitable thin-wall stainless steel tubing such as SUS304, SUS303, SUS302,1Cr18Ni9,1Cr18Ni9Ti, OCr18Ni9 or 1Cr17Ni8, tubing is carried out the corrugated stainless steel tubing 1 that spiral is processed into continuously (referring to Fig. 7), bellows-shaped adopts semicircle shape (referring to Fig. 3), guarantees intensity and flexible processability that stainless steel pipe is good.Red copper or the steel pipe 2 of choosing suitable caliber carry out an end enlarging 5, and once more 3 processing of horn mouth sealing surface are carried out in the another port of this adapter after putting brass or steel joint 4, and two ports of taking over enlarging 5 ends and corrugated stainless steel tubing are carried out the soldering welding.After finishing stainless steel connecting tube assembly is carried out the bending coiling, with instant packed and transportation.When the air-conditioning unit is installed, only need draw back the stainless steel connecting tube assembly of coiling shape, the needs according to put seat in the plane inside and outside the air-conditioning unit room change the connecting tube element shapes at any time, and the joint of two ends is threaded with the indoor and outdoor unit respectively, realize the circulation of refrigeration agent.
As other mode of executions of the present invention, can also be following situation at the corresponding construction described in the leading portion:
Corrugated stainless steel tubing can be the corrugated tube shape that tubing is carried out spiral processing discontinuous (referring to Fig. 8).
