Embodiment
The utility model proposes a kind of tubing alternate embodiments of pipeline connection part of air conditioner around the technological improvement problem that substitutes copper pipe with steel pipe, can reduce the domestic air conditioner cost of production greatly.The structure of the pipeline connection part that the utility model is provided below in conjunction with the drawings and specific embodiments is elaborated.
The structure of pipeline connection part 1 mainly comprises as shown in Figure 1: four-way valve 101, condenser connecting tube 102, muffler assembly 104, low pressure valve connecting tube 103, outlet pipe 105 are formed.Condenser connecting tube 102, muffler assembly 104, low pressure valve connecting tube 103, outlet pipe 105 all are connected on four valve ports of four-way valve 101, and the material of main part of four-way valve 101 is a copper.The utility model is used steel pipe Alloy instead of Copper Manifold technology on condenser connecting tube 102, muffler assembly 104, low pressure valve connecting tube 103, the material of these three kinds of pipe fittings is mainly based on steel pipe, and connect the steel copper sleeve at the two ends of three kinds of pipe fittings or directly connect copper spare, two ends as condenser connecting tube 102, muffler assembly 104 all are provided with the steel copper sleeve, and an end of low pressure valve connecting tube 103 directly connects copper low pressure valve 403.One end of three kinds of pipe fittings connects four-way valve 101, and the other end is connected with other parts of steel copper sleeve and air-conditioner refrigerating system.
See Fig. 2, condenser connecting tube 102 is made up of bend pipe 202, the steel copper sleeve 201 of steel copper sleeve 201, steel.
See Fig. 3, muffler assembly 104 by bend pipe 304, the steel copper sleeve 201 of the bend pipe 302 of steel copper sleeve 201, steel and steel, form.Muffler assembly 104 is provided with the multistage bend pipe, in order to reduce pipeline vibration and noise sound, the lengths of steel pipes of muffler assembly is divided into 304 two sections of bend pipe 302 and bend pipes, is in order to enhance productivity and to reduce the reject ratio of production.
See Fig. 4, low pressure valve connecting tube 103 is made up of steel copper sleeve 201, transition steel pipe 402 and low pressure valve 403.Wherein, low pressure valve 403 is that copper material makes, and transition steel pipe 402 directly welds with low pressure valve 403, rather than one section copper pipe of transition is connected with low pressure valve 403 again, has reduced the soldering point on the low pressure valve connecting tube, can reduce the use amount of copper, thereby reduce production costs.
Outlet pipe 105 welds with the relief opening of compressor, in the outlet pipe 105 high temperature, the high-pressure refrigerant that compressor is discharged, need bear bigger vibration stress, in order to prevent the disconnected hidden danger of managing or splitting pipe of outlet pipe, guarantee the reliability of whole pipe connection part, therefore, outlet pipe 105 of the present utility model adopts copper pipe.In like manner, four-way valve 101 and low pressure valve 403 still adopt copper material as main material.The elbow radius of outlet pipe 105 is greater than 2 times of copper pipe external diameter.
Because the corrosion resistance of steel pipe is not as good as copper pipe; the utility model is when carrying out with steel pipe replacement Application of Copper; the surface anticorrosion that has taken into full account steel pipe is handled; adopt the bend pipe or the transition steel pipe of tube material to adopt double layer anticorrosive erosion protection in each assembly of four-way valve of the present utility model; Fig. 5 is the steel-pipe construction cut-away view that the utility model uses; as shown in Figure 5; steel pipe substrate layer 503 is provided with two-layer protective layer; the first layer chemical coating is an electrophoretic layer 502, and second layer protective layer is a heat-shrinkable T bush layer 501.Electrophoretic layer 502 is by each the member's parts integral body electrophoretic process gained to the pipeline connection part; Adopt thermal shrinkable sleeve to coat then on the first layer protective layer, after solidifying 10 seconds to 15 seconds under 120 ℃ to the 180 ℃ temperature, promptly the surface forms a kind of pyrocondensation mantle.Like this, just can form electrophoresis corrosion protection and pyrocondensation mantle corrosion protection double effects.After pipeline connection part of the present utility model adopts double layer anticorrosive erosion protection; in continuous 1000 hours salt spray test; corrosion phenomenon does not appear in pipeline connection part surface; judge by experience; in working order down, can guarantee the pipeline connection part after using 8 years, still can keep outward appearance complete, corrosion do not appear.The steel pipe that the pipeline connection part is used, the main chemical mass percent meets the following conditions: C≤0.06%, Si≤0.03%, Mn≤0.40%, P≤0.03%, S≤0.03%, Al≤0.07%.
Simultaneously, in order to satisfy the special mechanical property requirement of steel pipe, on the condenser connecting tube 102 of assembly, muffler assembly 104, low pressure valve connecting tube 103, the bend pipe 304 of the bend pipe 202 of steel, the bend pipe 302 of steel and steel, the radius bend of transition steel pipe 402 are greater than 3 times of outer diameter of steel pipes, pipe deformation or wrinkling when purpose prevents bending.Specification for steel pipe is selected, and should adopt the steel pipe of external diameter 7mm, 8mm, 9.52mm, 12mm or 15.88mm, is pipeline external diameter commonly used on the air conditioner, and wall thickness is controlled between the 0.6mm to 0.8mm.Too thin then is that compressive strength reduces, and too thick then is processing difficulties, wrinkling easily.
Fig. 6 illustrates the structure of steel copper sleeve, at whole air conditioner be with the pipeline connection part, there are a plurality of parts to establish the steel copper sleeve in the end, make the application of steel pipe carry out the transition to copper pipe from steel pipe, make in the production scene, the workman can weld pipeline connection part and other refrigeration system component quickly and accurately.In the steel copper sleeve, steel pipe and copper pipe must guarantee enough weld lengths, could effectively guarantee the quality of connection of steel pipe and copper pipe,, be inserted into the technological scheme in the copper pipe behind the structure of the steel copper sleeve of the present utility model employing steel pipe draw again in conjunction with the heat transfer rate of steel and copper and the molten flow velocity degree of solder flux, and the insertion depth of steel pipe is 10mm to 20mm, the welding of steel pipe and copper pipe fusion length is greater than 5mm, its structure as shown in Figure 6, among the figure, 601 expression steel pipes, 602 expression copper pipes.
The steel copper sleeve can also adopt ultrasonic welding or crimping mode to connect.
More than be embodiment of the present utility model, but can not be as the restriction of the utility model claim.The change that all those skilled in the art are done under the situation of not making creative work is all at protection domain of the present utility model.
