Abstract
The utility model relates to a refrigeration compressor exhaust pipe connection structure which is characterized by mainly comprising a copper pipe (2c) and a connection component (7), wherein the connection component (7) is welded with a compressor upper cover (1) and can extend into a compressor chamber; the upper end of the copper pipe (2c) is connected with a system connection pipe (3), and the lower end is connected with the connection component (7); and the connection component (7) is welded with the compressor upper cover (1) so as to connect the exhaust pipe with the upper cover. The utility model can implement no leakage connection through conventional resistance welding or friction welding, is beneficial to improving the product quality, and has the advantages of high manufacturability and energy conservation.
Description
Technical field
The utility model relates to a kind of refrigeration compressor, the linkage structure of especially a kind of outlet pipe of refrigeration compressor and housing or loam cake, specifically a kind of refrigeration compressor exhaust pipe connection structure.
Background technique
The outlet pipe (sucking pipe) of refrigeration compressor all is copper pipe at present, this class row (suction) tracheae generally adopts the mode of flame (or high-frequency induction heating) welding to be welded on the loam cake or housing of irony, this kind mode of production can cause the welding leak-down rate high, and cost of production is high, wastes energy.For this reason, Chinese patent ZL 2,007 2 0035081.4 has carried out certain improvement, but also there is complex manufacturing technology in the exhaust pipe structure after this improvement, the problem that cost is high.
Summary of the invention
When the purpose of this utility model connects from loam cake for existing refrigeration compressor outlet pipe because the different not high problems of leaking of causing of welding quality that easily cause of material; design the compressor air-discharging pipe connecting structure that a kind of preparation process is simple, cost is low; thereby improve the outlet pipe welding quality; reduce energy consumption; reduce the leakage of refrigeration agent, protection of the environment.
The technical solution of the utility model is:
A kind of refrigeration compressor exhaust pipe connection structure, it is characterized in that it is mainly by copper pipe 2c be used for being weldingly connected with compressor top cover 1 and the connected element 7 that can stretch into compressor cavity forms, the upper end of described copper pipe 2c links to each other with system connecting tube 3, its lower end links to each other with connected element 7, described connected element 7 is split-type structural, contain in the split type connected element 7 with loam cake 1 and be welded to connect easily irony part, thereby this irony part is weldingly connected with compressor top cover 1 described outlet pipe is linked to each other with loam cake.
Described connected element 7 is comprised of iron hoop 2a and the Inserting Tube 2b as the irony part, described iron hoop 2a and compressor top cover 1 are weldingly connected, the lower end of copper pipe 2c is inserted among the iron hoop 2a and is weldingly connected, described Inserting Tube 2b is iron pipe, Stainless Steel Tube, aluminum pipe or plastic tube, and Inserting Tube 2b links to each other with iron hoop 2a and is arranged in compressor cavity.
The beneficial effects of the utility model:
The utility model has better solved the welding leakage problem of copper outlet pipe and compressor housing, for the quality that improves compressor important realistic meaning is arranged, and has simultaneously simple in structure, easily manufactured, technological advantage is conducive to manufacturing enterprise and saves production cost, and energy-saving effect is obvious.
The utility model can be realized connecting without leaking by conventional resistance welding or friction welding, is conducive to improve the quality of products manufacturability, energy saving.
The utility model can stretch in the compressor cavity with the pipe fitting (such as plastic tube, iron pipe, aluminum pipe etc.) that the material (non-copper pipe) of lower cost is made, and can greatly save cost.

Embodiment
Below in conjunction with drawings and Examples the utility model is further described.
Shown in Fig. 1-6.
A kind of refrigeration compressor comprises the pump housing 6, liquor separator 5, motor 4, loam cake 1, outlet pipe 2, system's connecting tube 3 etc., as shown in Figure 1.One end of outlet pipe 2 links to each other with loam cake 1, its the other end links to each other with system connecting tube 3, described outlet pipe 2 is comprised of copper pipe 2 c and connected element 7, and connected element 7 reaches the Inserting Tube 2b that links to each other with iron hoop by the iron hoop 2a of being convenient to link to each other with irony loam cake 1 or housing and forms, as shown in Figure 2.Iron hoop 2a is that irony connects flange or connecting flange structure.Iron hoop 2a and compressor top cover 1 are weldingly connected, the lower end of copper pipe 2c insert among the iron hoop 2a and be weldingly connected, described Inserting Tube 2b also links to each other with iron hoop 2a and is arranged in compressor cavity.
Different according to material and Placement, the iron hoop 2a of existing composition connected element 7 and Inserting Tube 2b adopt the overall structure of identical material mostly, such as Fig. 3.But the utility model is designed to Fig. 4 from the angle of the cost that saves material with iron hoop 2a and Inserting Tube 2b, Fig. 5, Split type structure shown in Figure 6, when adopting Split type structure, Inserting Tube 2b can be iron pipe, copper pipe or nonmetallic pipe (such as plastic tube), Inserting Tube 2b and iron hoop 2a can adopt welding, be spirally connected, riveted joint or bonding linking to each other, when being nonmetallic pipe, Inserting Tube 2b should link to each other with iron hoop 2a interference fit or bonding, Inserting Tube 2b links to each other with lower end welding or the bonding structure of iron hoop 2a among Fig. 4, Inserting Tube 2b is sleeved on the step surface of downward protrusion of iron hoop 2a among Fig. 5, among Fig. 6 Inserting Tube 2b by the flange reversal of the natural order of things iron hoop 2a on projecting inward step surface.
The utility model relates generally to the structure of outlet pipe, all the other do not relate to the part all the prior art that maybe can adopt same as the prior art realized.
