Abstract
The utility model relates to a throttling thin glass tube. The throttling thin glass tube is characterized by comprising more than two sections of thin glass tube bodies with different tube diameters. The thin glass tube bodies are mutually communicated in a parallel mode and are distributed in sequence from a small opening diameter to a large opening diameter. The throttling thin glass tube has the advantages of being free of a one-way valve, and capable of reducing production cost, reducing the number of welding junctions, reducing leakage hidden dangers and completely avoiding vibration noise produced by the one-way valve.
Description
Technical field
The utility model relates to a kind of throttle capillary tube, especially carries out a kind of throttle capillary tube in the air-conditioning refrigeration system of cooling and warming operation.
Background technology
Refrigeration plant such as cooling and warming air conditioner for both device, when carrying out the cooling and warming operation, refrigerant flow under two kinds of methods of operation requires different, is mainly that cold-producing medium flows through length difference capillaceous and realizes when changing the cooling and warming operation at present, usually adopts the structure as Fig. 1 when design.When refrigerating operaton, cold-producing medium enters from the A end of the first capillary 1, through the directly E end outflow of process check valve 2 after the first capillary 1 throttling.When heating operation, cold-producing medium enters from the E end of check valve 2, and because of the blocking effect of check valve 2, cold-producing medium enters through the D of the second capillary 3 end, hold through arriving C after 3 throttlings of the second capillary, then flow out through the A end from the first capillary 1 after the first capillary 1 second throttle.Adopting this structure Main Problems is to have increased check valve in throttle system, has not only increased material cost, has also increased the possibility that weld bond leakage and check valve produce noise.
Summary of the invention
The purpose of this utility model is overcome the deficiencies in the prior art and a kind of throttle capillary tube without check valve is provided, and no matter refrigeration system is when cooling and warming moves, and cold-producing medium all flows through same capillary and carries out throttling, with the purpose that reaches simplified structure, reduces costs.
In order to achieve the above object, the utility model is to realize like this, it is a kind of throttle capillary tube, it is characterized in that described throttle capillary tube comprises the capillary of different tube diameters more than two sections, and described each capillary is connected mutually and is communicated with and little of the large distribution of bore by bore successively.
Described throttle capillary tube comprises the first capillary and second capillary of two sections different tube diameters, and described the first capillary is connected mutually with the second capillary, and the first caliber capillaceous is little, the second caliber capillaceous
Greatly; In refrigeration system, as being described with refrigerating operaton, the first end capillaceous is connected with the high-pressure side of refrigeration system, and the second end capillaceous is connected with the low-pressure side of refrigeration system.
The utility model has following advantage compared with prior art:
(1) without check valve, reduce production costs;
(2) reduce weld bond, reduce and leak hidden danger;
(3) vibration noise of avoiding check valve to produce fully.
Description of drawings
Fig. 1 is the structural representation of prior art;
Fig. 2 is the structural representation of the utility model embodiment one;
Fig. 3 is the structural representation of the utility model embodiment two.
The specific embodiment
The below describes embodiment of the present utility model in detail, and the example of described embodiment is shown in the drawings, in figure from start to finish same or similar label represent same or similar element or the element with identical or similar functions.Be exemplary below by the embodiment that is described with reference to the drawings, only be used for explaining the utility model, and can not be interpreted as restriction of the present utility model.
In description of the present utility model, term " first " reaches " second " and only is used for describing purpose, and can not be interpreted as indication or hint relative importance.
Embodiment one
As shown in Figure 2, it is a kind of throttle capillary tube, and described throttle capillary tube 4 comprises the capillary of different tube diameters more than two sections, described each capillary connect mutually be communicated with and successively by bore little to the large distribution of bore or by bore greatly to the little distribution of bore.
In the present embodiment, described throttle capillary tube 4 comprises the first capillary 41 and second capillary 42 of two sections different tube diameters, described the first capillary 41 is connected mutually with the second capillary 42, the caliber of the first capillary 41 is little, the caliber of the second capillary 42 is large, and the first capillary 41 is formed by the second capillary 42 reducings; In refrigeration system, as being described with refrigerating operaton, the end of the first capillary 41 is connected with the high-pressure side of refrigeration system, and the end of the second capillary 42 is connected with the low-pressure side of refrigeration system.
During the refrigeration system refrigeration, cold-producing medium enters from the A end of the first capillary 41, flows out from the second capillary 42; C end from the second capillary 42 when heating enters, and flows out from the first capillary 41.In application process, the needs that internal diameter that can be by adjusting the first capillary 41 and the second capillary 42 and length satisfy different refrigeration systems.
Embodiment two
As shown in Figure 3, other the same with embodiment one, difference is that the first capillary 41 and the second capillary 42 are welded.Identical part no longer repeats to set forth.
Although illustrated and described embodiment of the present utility model, those having ordinary skill in the art will appreciate that: in the situation that do not break away from principle of the present utility model and aim can be carried out multiple variation, modification, replacement and distortion to these embodiment, scope of the present utility model is limited by claim and equivalent thereof.
Claims (2)
1. a throttle capillary tube, is characterized in that described throttle capillary tube (4) comprises the capillary of different tube diameters more than two sections, and described each capillary is connected mutually and is communicated with and little of the large distribution of bore by bore successively.
2. throttle capillary tube according to claim 1, it is characterized in that described throttle capillary tube (4) comprises the first capillary (41) and second capillary (42) of two sections different tube diameters, described the first capillary (41) is connected mutually with the second capillary (42), the caliber of the first capillary (41) is little, and the caliber of the second capillary (42) is large; In refrigeration system, as being described with refrigerating operaton, the end of the first capillary (41) is connected with the high-pressure side of refrigeration system, and the end of the second capillary (42) is connected with the low-pressure side of refrigeration system.
