Description

The Novel straw structure of reservoir
Technical field
The utility model relates to a kind of suction pipe of reservoir, is especially a kind of Novel straw structure of the reservoir be applied on rotary compressor.
Background technology
The reservoir of existing rotor-type compressor, its suction pipe used, mainly contain following two kinds of conventional structures: scheme 1, as shown in Figure 1, suction pipe 4 is welded into L shape body by iron straight tube 41 and copper bend pipe 42 by furnace brazing technology, its iron straight tube 41 part is arranged in reservoir, and copper bend pipe 42 part is extended outside reservoir; The reservoir suction pipe 4 of above-mentioned this structure, has the following disadvantages: the copper pipe section 42 in (1) suction pipe 4 is longer, causes the increase of suction pipe 4 manufacturing cost; (2) suction pipe 4 is welded by iron and copper bi-material and makes, and increases the producting process difficulty of suction pipe 4 self; (3) enlarging shape is arranged in iron pipe section 41 one end of suction pipe 4, and be enclosed within the outer wall of copper pipe section 42 one end by this enlarging one end, that is: be welded to connect between the inwall of iron pipe 41 enlarging place and copper pipe 42 one end outer wall, by the little restriction of flared section area of iron pipe 41, cause their junction area less, not prison welding is solid, and weld easily leaks.
Scheme 2, as shown in Figure 2, for another suction pipe 5 of reservoir, suction pipe is L-type iron suction pipe 5, this iron suction pipe 5 also needs copper pipe 6 in welding at its tail end, but because iron suction pipe 5 is iron pipe, without the need to bi-material is welded when iron suction pipe 5 manufactures, simplify the production technology of iron suction pipe 5 to a certain extent, and, iron suction pipe 5 afterbody is without the need to using copper pipe, also reduce the manufacturing cost of iron suction pipe 5, but, this iron suction pipe, still have the following disadvantages: (1) iron suction pipe 5 tail end is arranged to enlarging shape, and be enclosed within the outer wall of external copper pipe 6 one end by this enlarging one end, that is: be welded to connect between the inwall of iron suction pipe 5 enlarging place and external copper pipe 6 one end outer wall, by the little restriction of flared section area of iron suction pipe 5, cause their junction area also less, weld insecure all the time, (2) sealing in view of reservoir requirement is high, the unit slip of suction pipe requires extremely low, significantly, between the inwall of this iron suction pipe 5 enlarging place and external copper pipe 6 one end outer wall, bonding area is too small, causes welded seal poor, easily because solder side leaks, instructions for use cannot be met, therefore, the suction pipe of this structure still cannot really be applied, and is at least difficult to promote the use of.
Utility model content
The purpose of this utility model is to overcome all deficiencies that above-mentioned prior art exists, and the letter of a kind of structure is provided, rationally, technique is simple and easy, cost is low, can realize full-automatic production, firm welding and the Novel straw structure of the high reservoir of sealing.
The purpose of this utility model is achieved in that
The Novel straw structure of reservoir, comprises the iron pipe section of L-type, and iron pipe section two ends are respectively top and tail end, it is characterized in that, also include copper pipe section, and the inwall of copper pipe section one end and the outer wall of described iron pipe section tail end are linked together by furnace brazing; This kind of Novel straw structure, L-type iron pipe section is made up of iron pipe entirety, the inwall of copper pipe one end and the outer wall of iron pipe section tail end are welded to connect, that is: iron pipe section tail end is without the need to enlarging, and, the welding manner of this copper pipe section cover iron pipe section, make both contact area greatly increase, significantly improve fastness and the sealing of both connections, and technique is simple and easy, cost is low, and the full-automation being particularly useful for pipe fitting manufacturing enterprise is produced; And this Novel straw structure, it is simple and reasonable for structure, implements easily.
The utility model can also adopt following technical measures to solve:
As scheme more specifically, described copper pipe section one end is nested with on the outer wall of iron pipe section tail end, and contact surface is between the two for being welded to connect.
The beneficial effects of the utility model are as follows:
(1) this kind of suction straw, L-type iron pipe section is made up of iron pipe entirety, the inwall of copper pipe section one end and the outer wall of iron pipe section tail end are welded to connect, that is: iron pipe section tail end is without the need to enlarging, and, the welding manner of this copper pipe section cover iron pipe section, make both contact area greatly increase, significantly improve fastness and the sealing of both connections, and technique is simple and easy, cost is low, and the full-automation being particularly useful for pipe fitting manufacturing enterprise is produced; And this Novel straw structure, it is simple and reasonable for structure, implements easily.
Accompanying drawing explanation
Fig. 1 is reservoir suction pipe embodiment one schematic diagram of existing rotor-type compressor;
Fig. 2 is reservoir suction pipe embodiment two schematic diagram of existing rotor-type compressor;
Fig. 3 is the schematic diagram of the reservoir suction straw of the utility model rotor-type compressor.
Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is described in further detail.
As shown in Figure 3, the Novel straw structure of reservoir, comprises the iron pipe section 1 of L-type, iron pipe section 1 two ends are respectively top and tail end, it is characterized in that, also include copper pipe section 2, the inwall of copper pipe section 2 one end and the outer wall of described iron pipe section 1 tail end are linked together by furnace brazing.
As scheme more specifically, described copper pipe section 2 one end is nested with on the outer wall of iron pipe section 1 tail end, and contact surface is between the two for being welded to connect.
This kind of suction straw, L-type iron pipe section 1 is made up of iron pipe entirety, the inwall of copper pipe section 2 one end and the outer wall of iron pipe section 1 tail end are welded to connect, that is: iron pipe section 1 tail end is without the need to enlarging, and, this copper pipe section 2 overlaps the welding manner of iron pipe section 1, make both contact area greatly increase, significantly improve fastness and the sealing of both connections, and technique is simple and easy, cost is low, and the full-automation being particularly useful for pipe fitting manufacturing enterprise is produced; And this Novel straw structure, it is simple and reasonable for structure, implements easily.
