Abstract
The utility model pertains to a refrigerating system, particularly relates to a reducer capillary tube for a refrigeration system, comprising the tube bodies of a first part and a second part. A reducer segment tube body is arranged between the tube body of the first part and the tube body of the second part. The utility model adopts capillary tubes processed by multi-pass stretching and free of welding, and as a result, leakage and blocking due to welding are avoided; the production cost is largely reduced; and the noise is removed.
Description
Technical field
The utility model belongs to refrigeration system, relates in particular to a kind of refrigeration system undergauge capillary.
Background technology
Existing refrigeration system is in when operation, and compressor compresses refrigerant also enters it in the condenser.When refrigerant liquid stream ran into capillary, it was restricted, thereby caused that refrigerant pressure increases in the condenser; When the high-pressure refrigerant that has been compressed flows out capillary and flows into the jumbo evaporimeter of low pressure, the also evaporation of expanding of this refrigerant, thus cause that the temperature in the evaporimeter descends.The refrigerant of this moment is gaseous state, and it shifts to compressor then, and circulation and so forth realizes refrigeration.Capillary is one of vital part in the refrigeration system.Design feature capillaceous is: comprise first and second portion at least, the first of thin end is an inlet capillaceous, second portion than butt end is the capillary liquid outlet, and inlet links to each other with the liquid outlet of condenser, and liquid outlet capillaceous links to each other with the inlet of evaporimeter.Producing capillary all adopts the mode with first and second portion welding to form capillary.Its shortcoming is: first and second portion easily form the space, cause capillary can to make a noise because of the backflow that this space produces when work; Simultaneously, the capillary caliber is very little, easily produces the stifled phenomenon of weldering.
The utility model content
The purpose of this utility model is to overcome the deficiency of above-mentioned technology, and provide a kind of refrigeration system undergauge capillary, it adopts repeatedly stretching technique to form the capillary of multistage transition, adopted the overall structure that need not weld, eliminated because welding makes capillary produce the stifled defective of weldering and avoided leakage; Increased the flowability of cold-producing medium simultaneously, enlargement discharge improves refrigerating capacity.
The utility model for achieving the above object, by the following technical solutions: a kind of refrigeration system undergauge capillary comprises it is characterized in that the body of first and second portion: be provided with undergauge section body between described first body and the second portion body.
Described first pipe diameter is less than the second portion pipe diameter.
The undergauge section body of described first body is provided with the second transition undergauge section body.
Described first body, second portion body and undergauge section body are that same body constitutes.
Described second portion body 2/3 part is provided with diameter shrinkage part.
The beneficial effects of the utility model: it adopts repeatedly stretching technique to form the capillary of multistage transition undergauge, do not need welding, eliminated because of the recurrent leakage phenomenon of welding, can not produce because the stifled phenomenon of the weldering that is welded yet, effectively reduce manufacturing cost, and can play the effect that abates the noise.

Fig. 2 is the structural representation of the utility model embodiment 2.
The specific embodiment
Embodiment 1
As shown in Figure 1, a kind of refrigeration system undergauge capillary comprises the body 1,2 of first and second portion being provided with undergauge section body 3 between first's body and the second portion body.First's pipe diameter is less than the second portion pipe diameter.Described first body, second portion body and undergauge section body are that same body constitutes.
Embodiment 2
As shown in Figure 2, the undergauge section body of described first body is provided with the second transition undergauge section body 4.
Above-mentioned second portion body 2/3 part is provided with diameter shrinkage part 5.The length of first's body should be grown (deciding on designing requirement), and the length of second portion body and undergauge section body is then short.This structure is except that having anticlogging characteristics, and its second portion body and undergauge section body can play the effect that abates the noise.Make liquid communication more happy simultaneously, can improve refrigeration.
The above only is preferred embodiment of the present utility model, is not structure of the present utility model is done any pro forma restriction.Every foundation technical spirit of the present utility model all still belongs in the scope of the technical solution of the utility model any simple modification, equivalent variations and modification that above embodiment did.
Claims (5)
1. refrigeration system undergauge capillary comprises it is characterized in that the body of first and second portion: be provided with undergauge section body between described first body and the second portion body.
2. refrigeration system undergauge capillary according to claim 1 is characterized in that: described first pipe diameter is less than the second portion pipe diameter.
3. refrigeration system undergauge capillary according to claim 1 is characterized in that: the undergauge section body of described first body is provided with the second transition undergauge section body.
4. refrigeration system undergauge capillary according to claim 1 is characterized in that: described first body, second portion body and undergauge section body are that same body constitutes.
5. refrigeration system undergauge capillary according to claim 1 is characterized in that: described second portion body 2/3 part is provided with diameter shrinkage part.
