Description
Technical field
The present invention relates to a kind of idle call system pipeline part, particularly relate to a kind of novel supercooling tube group assembly.
Background technology
The main condenser of refrigeration system, compressor, evaporimeter, supercooling tube group connect and compose, and supercooling tube group is throttling original paper, and its effect realizes reducing pressure by regulating flow to the cold-producing medium of high pressure-temperature by restricting element, thus obtain the cold-producing medium of low-temp low-pressure.In the process pipe group design process of prior art, exist following bad:
1, identical with the pipe external diameter that filter connects with capillary; forward and reverse equal energy proper engagement inserts; if operative employee is unfamiliar with or maloperation time all likely anti-inserted; because supercooling tube group is anti-inserted; delivery temperature rises; find that when taking a sample test cooling operation shuts down phenomenon, and when heating, temperature is lower, heating effect is also very poor.
2, because too thin (the such as external diameter 2.7 of capillary inner diameter, internal diameter 1.4), cannot convex be made, make producer when producing capillary, inserting filter depth uncontrollable, when capillary inserts and crosses dark in filter, screen pack top, on screen pack, can be out of shape by top, forms half and blocks up, cooling or heating effect declines, and not easily finds (bad during fashion in operation).
Summary of the invention
The object of the invention is to overcome defect that above-mentioned prior art exists and provides one to prevent the anti-inserted and more rational novel supercooling tube group assembly of design of employee.
For solving the problems of the technologies described above, the present invention takes following technical scheme:
A kind of novel supercooling tube group assembly, the filter comprising capillary and be connected respectively with described capillary two ends and capillary tube connector, one section of transition conduit is provided with between described capillary and filter, described transition conduit is provided with a salient point and a concave point, it is spacing that described salient point is used for assembling between transition conduit and filter, described concave point be used for transition conduit and intercapillary assembling spacing; Filter tube connector is also provided with at the other end of described filter.
Preferably, described capillary is pricked by line and is fixed into cast.
Preferably, described capillary tube connector is different with filter tube connector external diameter.
Compared with prior art, beneficial effect of the present invention is:
The advantage that a kind of novel supercooling tube group assembly of the present invention has:
1) supercooling tube group two ends adopt capillary tube connector and the filter tube connector of various outer diameter, avoid anti-inserted;
2) capillary takes over one end increase transition conduit (such as external diameter 4.76mm's) of filter, in this transition conduit, coordinate one end to do to locate with capillary recessed, control capillary and insert the degree of depth in transition conduit, then do convex with filter fits one end, control transition conduit and insert filter depth.
Accompanying drawing explanation
Fig. 1 is the main TV structure schematic diagram of the present invention;
Fig. 2 is that the present invention improves pre-structure schematic diagram.
Detailed description of the invention
Shown in accompanying drawing 1, a kind of novel supercooling tube group assembly, the filter 2 comprising capillary 1 and be connected respectively with described capillary 1 two ends and capillary tube connector 3, one section of transition conduit 4 is provided with between described capillary 1 and filter 2, described transition conduit 4 is provided with an a salient point 4-1 and concave point 4-2, the assembling that described salient point 4-1 is used between transition conduit 4 and filter 2 is spacing, and the assembling that described concave point 4-2 is used between transition conduit 4 and capillary 1 is spacing; Filter tube connector 5 is also provided with at the other end of described filter 2.
Preferably, described capillary 1 is pricked 6 by line and is fixed into cast.
Preferably, described capillary tube connector 3 is different with filter tube connector 5 external diameter.
Described in accompanying drawing 2, the supercooling tube group assembly of prior art, adopt capillary 1 and filter 2 directly erection welding that external diameter is very thin, because capillary 1 external diameter is very little, the design of spacing sags and crests cannot be realized on capillary 1, in the installation process of reality, very easily capillary 1 is inserted into the screen pack 2-1 position of filter 2, light then screen pack 2-1 can be caused to be out of shape, heavy then screen pack 2-1 directly penetrates, and loses the filtering function of screen pack 2-1; In addition; original design have employed the identical capillary tube connector 3 of external diameter and filter tube connector 5; in actual production process; employee is very easily easily anti-inserted; after supercooling tube group assembly is anti-inserted, delivery temperature rises, and finds that cooling operation shuts down phenomenon when taking a sample test; and temperature is lower when heating, heating effect is also very poor.
The present invention is reasonable in design, and structure is simply more suitable for needs of production, has the following advantages:
1 supercooling tube group two ends adopt capillary tube connector 3 and the filter tube connector 5 of various outer diameter, avoid anti-inserted;
2) capillary 1 takes over one end increase transition conduit 4 (such as external diameter 4.76) of filter 2, in this transition conduit 4, coordinate one end to do with capillary 1 and locate recessed 4-2, control capillary 1 and insert the degree of depth in transition conduit, coordinate one end to be then convex 4-1 with filter 2, control transition conduit 4 and insert filter 2 degree of depth.
