Description
Technical field
The utility model relates to air conditioner connecting pipe technical field, is specifically related to a kind of new type stainless steel. corrosion resistance air conditioner connecting pipe.
Background technique
The connection of indoor apparatus of air conditioner and outdoor unit, needs connecting material to connect.Being widely used in the material that indoor apparatus of air conditioner is connected with outdoor unit is copper pipe and aluminum pipe.At present, air-conditioning connecting material uses the most generally air-conditioning copper pipe.Why? because refrigeration agent is finally will absorb heat in vaporizer, then release heat within the condenser, also will be connected with radiating fin outside air-conditioning copper pipe, what pass through in connecting tube is refrigeration agent.So the copper pipe quality of this refrigeration agent directly affects the refrigeration of air-conditioning.
The compression resistance of copper pipe is high, not perishable, and working life is also long than aluminum pipe; The thermal conductivity of refrigeration copper tube will be good than aluminum pipe many, welding performance, mechanical strength are also good more than aluminium, certain air-conditioning copper pipe in price also can be more expensive than aluminum pipe.A lot of Consumer is in order to save money or seek cheap, refrigerator, air conditioner copper pipe change thin or directly use aluminum pipe instead by they, price just relative step-down, but far short of what is expected certainly than with copper pipe of performance, refrigeration does not use the good refrigeration effect of copper pipe yet.
Connecting refrigerant lines in existing air-conditioning is copper pipe and is connected, and because copper material price is high, makes copper pipe price high, improves the manufacture cost of air-conditioning.At present in connecting tube field, there is the scheme of a lot of material substitution aspect, such as carbon steel replacement scheme, but carbon steel substitutes must solve problem of rustiness, need to be coated with corrosion resistant coating, tube interior also will carry out anticorrosion, and product can not be placed too of a specified duration in atmosphere, therefore cause product cost still higher, also there is hidden danger of quality simultaneously.Use the product of aluminum pipe replacement scheme to relate to copper and aluminium welding contact process galvanic corrosion problems, cause high cost, quality is unstable, and life of product is low.
When the mode adopting Stainless Steel Tube to be connected with copper pipe, if Stainless Steel Tube tube wall is blocked up, then adds the rigidity of stainless-steel pipe, add cost of material.When Stainless Steel Tube tube wall is thin, its tube wall is connected with copper pipe, contacts with each other apart from short, connect firm not, and when the end of copper pipe is connected with the tube wall of Stainless Steel Tube, because Stainless Steel Tube tube wall is circular arc, it welds difficulty, Stainless Steel Tube tube wall easily burns by welding, weld strength is not high, and impact uses, therefore, existing Stainless Steel Tube is connected more with copper pipe be that end is connected with end, has certain limitation when this Placement makes Stainless Steel Tube use.
The Stainless Steel Tube connecting tube of prior art is at the tube wall place perforating by punching needing through hole of Stainless Steel Tube, and shaping multiple through hole, the tube wall of the Stainless Steel Tube around through hole is shaped to planar wall, and connecting tube needs to extrude annular protrusion, process more complicated, is not easy to enforcement.
Summary of the invention
The purpose of this utility model is defect for prior art and deficiency, provides the new type stainless steel. corrosion resistance air conditioner connecting pipe that a kind of structure is simple, reasonable in design, easy to use.
For achieving the above object, the technical solution adopted in the utility model is: it comprises Stainless Steel Tube, connects square, connecting tube, sealed pipe inipple, pipe thread, jointing, pipe thread hole; The tube wall of described Stainless Steel Tube is welded with connection square; One end of described sealed pipe inipple is provided with pipe thread, and the other end of sealed pipe inipple is provided with jointing; Described connection square and stainless steel tube wall are provided with the pipe thread hole communicated, and pipe thread hole coordinates with pipe thread; One end of described Stainless Steel Tube is welded with jointing.
As preferably, the thickness of described connection square is d, and the foot welding height connected between square 2 and Stainless Steel Tube 1 is 2d/3.
As preferably, the internal diameter of described jointing is less than the external diameter of connecting tube 3.
As preferably, the pipe wall thickness of described Stainless Steel Tube is 0.1 ~ 1.0mm; Connecting tube is copper tube.
During the utility model operation, only square be need be welded to connect on stainless steel tube wall, processing tube tapped hole, sealed pipe inipple and Stainless Steel Tube connected, then welding connecting tube and sealed pipe inipple.
After adopting said structure, the beneficial effect that the utility model produces is: new type stainless steel. corrosion resistance air conditioner connecting pipe described in the utility model, easy to process, reduce the pipeline bending point in connecting refrigerant lines road, reduce the manufacture cost of air-conditioning refrigerant connecting pipeline, enhance productivity, the utility model have structure simple, arrange rationally, the advantage such as fabricating cost is low.
