Abstract
The utility model discloses an air-conditioner shunting tube stack which is arranged at the inlet and outlet ends of a heat exchanger of an indoor unit of a heat pump air conditioner and achieves an effect of flow shunting and combining. The air-conditioner shunting tube stack comprises a branch pipe, a shunt, a main pipe, a joint and a nut, wherein the branch pipe and the shunt are made of red copper material, the joint and the nut are made of brass material, the main pipe is composed of a stainless steel corrugated pipe at the middle section and copper transition pipes at the two ends. The air-conditioner shunting tube stack is low in manufacturing cost and has the effects of noise reduction and vibration attenuation; and the tube stack is convenient to use, and not rusted in the process of using.
Description
Technical field
The utility model relates to air-conditioner hose spare field, particularly relates in the heat pump type air conditioner heat exchanger indoor unit into and out of the by-pass tube group of oral area.
Background technology
In the prior art, be installed in the by-pass tube group of heat pump air conditioner heat exchanger indoor unit import and export end, refrigerant in the air conditioner room unit heat exchanger is played gas collection, shunting action, comprise bypass duct, shunt, the person in charge, joint and nut, be responsible for the helical spring that a pipe bent position periphery is with the steel wire making, so that when should the pipe group specifically using, when adjusting joint closure, angle, crooked person in charge to prevent to be responsible for curved flat, distortion.Arm, shunt, the person in charge are all copper tube and make, and joint and nut are that brass is made, and with the P-Cu Brazing Materials one that is welded, because copper material price height, therefore, pipe assembly cost is corresponding also high between arm, shunt, the person in charge, joint.The by-pass tube group that the irony person in charge and copper arm etc. are welded has appearred on the existing market, but ferrous material instead of copper material, the scolder of use generally must adopt silver-base solder, and the silver-base solder cost is not low yet; And the pipeline of irony easily gets rusty, and cold-producing medium is good cleaning agent, and during pipeline inner refrigerant circulation, iron rust is easy to peel off back being transported in other refrigeration parts with cold-producing medium and damages miscellaneous part.
Summary of the invention
Purpose of the present invention is exactly to overcome the defective of forming this height or easily getting rusty with the means for air conditioner by-pass tube, provides a kind of cost relatively low, the air-conditioner by-pass tube group that serviceability is good.
For achieving the above object, air-conditioner by-pass tube group of the present utility model, comprise arm, shunt, the person in charge, joint and nut, arm, shunt are made for the red copper material, joint, nut are made for the brass material, it is characterized in that the described person in charge is that the copper transition conduit that weld at corrugated stainless steel tubing, its two ends is formed by the stage casing.
Preferably, described person in charge stage casing corrugated stainless steel tubing is the helical fissure pipe.
Optionally, described person in charge stage casing corrugated stainless steel tubing is a ring bellows.
Preferably, the copper transition conduit at described person in charge's stage casing corrugated stainless steel tubing and its two ends is welded as the furnace brazing of gas shield
Preferably, the used solder of copper transition conduit welding at described person in charge's stage casing corrugated stainless steel tubing and its two ends is bronze solder.
Preferably, described person in charge stage casing corrugated stainless steel tubing is kept away the thick 0.2～0.5mm of being.
Owing to be responsible for corrugated stainless steel tubing described in the aforementioned tube group and substitute copper tube, saved wire spring, therefore overall cost can reduce, because bellows has noise reduction, damping effect, and bending is put just, therefore, can reduce the noise and the vibration of air conditioner room unit, install and use and put just, and avoided getting rusty of iron pipe conduit spare use.

Fig. 1 (a) is the front view of air-conditioner by-pass tube group of the present utility model;
Fig. 2 (b) is the left view of air-conditioner by-pass tube group of the present utility model.
The specific embodiment
Describe the embodiment of the utility model air-conditioning organ pipe group below with reference to the accompanying drawings in detail.Fig. 1 (a) is the front view of air-conditioner by-pass tube group of the present utility model, and Fig. 2 (b) is the left view of air-conditioner by-pass tube group of the present utility model.It comprises arm 5, shunt 4, the person in charge 3 and joint 2 and nut 1, arm 5, shunt 4 is made for the red copper material, joint 2, nut 1 is made for the brass material, because diagram air-conditioner by-pass tube group is to be contained in advancing of air conditioner room unit heat exchanger, the port of export, by air-conditioner manufactory welded and installed, therefore, its arm 5 is made for copper pipe, so that with the convenient welding of air conditioner room unit heat-exchanger brass pipe mouth end, the quantity of arm 5 and caliber size by with the heat exchanger indoor unit design decision of its installation, in the other end and air conditioner chamber of pipe group, the tube connector of outer machine joins, so it is provided with joint 2 and nut 1.
Be responsible for 3 by the stage casing be corrugated stainless steel tubing 3 ', copper transition conduit 3a, the transition conduit 3b of its two ends welding form, used corrugated stainless steel tubing 3 ' can be ring bellows, can be the helical fissure pipe also, consider overall cost reason, preferentially adopt the helical fissure pipe.Because the tensile strength of stainless steel tube is bigger than copper pipe; the stainless steel tube of identical wall thickness is more much higher than copper tube compressive resistance; therefore; during specific design; used stainless bellows is more many than copper pipe wall thickness; preferentially selecting for use and being responsible for 3 stage casing corrugated stainless steel tubing 3 ' wall thickness is 0.2～0.5mm; for guaranteeing to be responsible for welding quality and low cost; the furnace brazing of gas shield is preferentially recommended in the welding of corrugated stainless steel tubing and its copper transition conduit in two ends; used solder is a spelter bronze; during concrete the welding, the brazier temperature is controlled at 900 ℃～1060 ℃, and pipeline fitting passes through the speed of brazier at 0.25～0.6 meter/minute.
More than the manufacturing process of pipe assembly is such: the first step, be responsible for 3 preparations, and the stage casing corrugated stainless steel tubing 3 of preparation design length '; Transition copper pipe 3a, the 3b of intercepting design length; an and end enlarging; after cleaning up respectively; corrugated stainless steel tubing 3 ' two ends put transition copper pipe 3a and 3b respectively; at corrugated stainless steel tubing 3 ' put the bronze wire weld-ring with transition copper pipe socket diplomatic circles place; put into the tunnel stove of nitrogen hydrogen mixeding gas or pure hydrogen protection then, finish welding.In second step, arm, shunt, joint are prepared, and usefulness such as clean up; The 3rd step is for assembling, with arm, shunt soldering, shunt and the transition conduit soldering of being responsible for an end, be responsible for other end transition conduit again with joint brazing.In the 4th step, leak detection checks that each weld must not let out; The 5th the step, the bend pipe shaping and screw on nut after pack.
Above by-pass tube group main leg substitutes copper pipe with corrugated stainless steel tubing, because bellows has noise reduction, damping effect, and bellows is crooked flexible good, therefore, can wholely reduce noise of indoor unit of air conditioner and vibration, and it is convenient to adjust angle, again owing to omitted the flat spring of curved anti, therefore, overall cost can reduce.
The above only is a preferred implementation of the present invention; should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the principle of the invention; can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.
