Abstract
The utility model discloses a connecting structure of a gas connection pipe, which mainly comprises an inner pipe and an outer pipe. One end of the inner pipe (1) is sleeved with one end of the outer pipe to form a joint, a joint sleeve is jacketed outside the joint and is fixedly connected with the inner pipe in a position close to the joint, the parts of the inner pipe and the outer pipe on the joint are fixedly connected through an annular extrusion joint sleeve, the joint sleeve is provided with at least one exhaust hole, and the exhaust hole is arranged in a gas retention area formed between the joint sleeve and the joint. The utility model has the advantages that: the gas retention area is provided with at least one exhaust hole to stabilize the pressure in the connection position, thereby ensuing the annular extrusion effect and the connection tightness of the inner pipe and the outer pipe. Moreover, the utility model also has the advantages of simple use, low skill requirements for workers, easy processing, low cost, and high production efficiency.
Description
Technical field
The utility model relates to a kind of annular extrusion technology that adopts with two structures that pipe is fixedly connected.
Background technique
In a lot of fields, usually use the annular extrusion method that stereoplasm tube is fixedlyed connected with flexible pipe.For example, be to take this annular extrusion Placement when the compressor with car air conditioner is connected with condenser at present.Below be the linkage structure of gas connection pipe in the example explanation prior art when being connected with condenser with the compressor of car air conditioner.
Automobile air conditioner compressor is the critical piece of formed automobile air-conditioning refrigeration system, divides evaporation zone (low pressure area) and condensing zone (zone of high pressure) in the work loop of compressor.Air condition compressor extracts refrigeration agent and delivers to zone of high pressure cooling after compression and condense from low pressure area, give out heat in air by radiating fin, and refrigeration agent is also from the gaseous state liquefy, and pressure raises.Refrigeration agent flows to low pressure area from the zone of high pressure again, is ejected in the vaporizer by capillary tube, and pressure drop, liquid refrigerant become gaseous state immediately, absorbs a large amount of heat in the air by radiating fin.And the connecting tube of compressor is used to connect compressor and condenser.
The interior pipe of existing automobile air conditioner compressor connecting tube and outer tube are owing to form the gas hold-up district between sleeve and outer tube after the annular extrusion, the gas that is full of in this gas hold-up district can influence the effect of annular extrusion; In addition, because the expansion of this part gas annular extrusion was lost efficacy, thereby pipe is connected defective tightness with outer tube in causing, the possibility of result can cause the generation of leaking gas after connecting tube is heated.Can influence the usability of air-conditioning like this.
The model utility content
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of linkage structure of gas connection pipe is provided, to improve the tightness that is connected between stereoplasm tube and the flexible pipe.
For achieving the above object, technical solution adopted in the utility model is: pipe and outer tube in the linkage structure of this gas connection pipe mainly comprises, one end of interior pipe and an end of the outer tube formation joint that connects together, described joint is with adapter sleeve outward, this adapter sleeve is being fixedlyed connected with interior pipe near described joint, pipe is mutually permanently connected by the annular extrusion adapter sleeve in the position at joint place with outer tube and is in the same place in described, adapter sleeve has at least one exhaust port, the place, gas hold-up district that this exhaust port forms between adapter sleeve and joint.
Further, interior pipe described in the utility model is stereoplasm tube, and outer tube is a flexible pipe.
Compared with prior art, the beneficial effects of the utility model are: gas hold-up district place has exhaust port and has guaranteed that the air pressure of joint is constant and be barometric pressure, avoided the connection of initiation lax because gas expands, prevent that annular extrusion lost efficacy, thereby avoid the gas leakage of losing efficacy and to cause because of annular extrusion, that has improved interior pipe and outer tube is connected tightness and Security.In addition, connecting tube processing of the present utility model is simple, easy to operate, and is low to labor claim, the manufacturing efficiency height, and cost is low.
Description of drawings
Fig. 1 is the structure sectional view of the linkage structure of the utility model gas connection pipe;
Among the figure, 1. in pipe, an end of pipes in 11., 2. adapter sleeve, 21. exhaust ports, 22. annular extrusion impressions, 3. outer tube, an end of 31. outer tubes, 4 gas hold-up district, 5. joints.
Embodiment
As shown in Figure 1, an end 31 of an end 11 of interior pipe 1 and outer tube 3 is connected together form joint 5.The intersection of an end 31 of pipe 1 end 11 and outer tube 3 in this joint 5 is meant, in Fig. 1, reference character 5 show the rising of this joint, stop bit put and be in the rising of intersection, the stop bit of an end 31 of an end 11 of pipe 1 and outer tube 3 put.
The joint 5 outer adapter sleeves 2 that are with, this adapter sleeve 2 is being fixedly connected near joint 5 places and interior pipe 1, this is fixedly connected and can adopts interference fit, welding or other connecting mode, then an end 11 of interior pipe 1 intersection (being joint 5) with an end 31 of outer tube is fixedly connected by annular extrusion adapter sleeve 2.Because annular extrusion can form annular extrusion impression 22 on outer tube 3, thereby between adapter sleeve 2 and joint 5, form gas hold-up district 4.Have at least one exhaust port 21 at 4 places, gas hold-up district this moment, so that the gas that is detained in the gas hold-up district 4 is in time discharged, avoids causing annular extrusion to lose efficacy, thereby avoid being connected of interior pipe 1 and outer tube 3 lax.
Tracheae linkage structure of the present utility model not only can be used for the compressor of car air conditioner and the connecting tube between the condenser, can also be used for other and use annular extrusion to fix the occasion of the Placement of two pipes.For example from the connection of the evaporator to compressor of air-conditioning, just can use this linkage structure, to improve the tight part of connection and the Security of connecting tube.
Claims (2)
1. the linkage structure of a gas connection pipe, it is characterized in that: comprise interior pipe (1) and outer tube (3), one end (11) of interior pipe (1) connects together with an end (31) of outer tube (3) and forms joint (5), described joint is with adapter sleeve (2) outward, this adapter sleeve (2) is being fixedlyed connected with interior pipe (1) near described joint, pipe (1) and outer tube (3) are mutually permanently connected together by annular extrusion adapter sleeve (2) in the position at joint place in described, adapter sleeve (2) has at least one exhaust port (21), and this exhaust port (21) is positioned at the gas hold-up district (4) that forms between adapter sleeve (2) and the joint and locates.
