Embodiment

Embodiment of the present utility model is described with detailed reference to accompanying drawing now.Now with detailed reference to of the present utility model excellent Embodiment is selected, its example is shown in the drawings.In the case of any possible, it will be marked and using identical in all of the figs Represent same or analogous part.In addition, although the term used in the utility model is selected from public term Select, but some terms mentioned in the utility model specification are probably applicant to be selected by his or her judgement , its detailed meanings illustrates in the relevant portion of description herein.In addition, it is desirable to not only by used actual art Language, and the meaning that is also to be contained by each term understands the utility model.

Refer to the attached drawing discusses general principle of the present utility model and preferred embodiment in more detail.

With reference first to Fig. 4 and Fig. 5, they show one embodiment according to pipeline connecting parts of the present utility model.This The pipeline connecting parts 3 of utility model mainly include：One housing, 31, first oil pipes 32 and second oil pipe 33.Housing 31 have top and bottom.One end of first oil pipe 32 is extended from the bottom of housing 31, and the other end position of the first oil pipe 32 In housing 31 and the top of housing 31 is extended to, i.e., is had between the port of the other end of the first oil pipe 32 and the top of housing 31 There is less gap, such as the gap is less than or equal to a certain predetermined threshold value.In addition, one end of the second oil pipe 33 is from housing 31 Top is extended, and the other end of the second oil pipe 33 is located in housing 31 and extends to the bottom of housing 31, i.e. the second oil pipe 33 The port of the other end and the bottom of housing 31 between there is less gap, such as the gap is less than or equal to a certain default threshold Value.

The pipeline connecting parts 3 are typically placed vertically in the form of shown in Fig. 4 and Fig. 5 when in use, accordingly even when the pipeline The fluid liquid level of the inside of connector 3 is relatively low, the lower port (other end of the second i.e. above-mentioned oil pipe 33) of the second oil pipe 33 Still it is immersed in below fluid, and then ensures from the upper port (one end of the second i.e. above-mentioned oil pipe 33) of the second oil pipe 33 to oil Case output is fluid all the time, avoids air from entering fuel tank.

Further, in the embodiment shown in fig. 5, pipeline connecting parts 3, which may further include, is arranged in housing 31 Two support members 34.The side of support member 34 is fixed on housing 31 and opposite side is fixing the first oil pipe 32 and/or Two oil pipes 33.The support member 34 can avoid the upper port of the first oil pipe 32 and/or the lower port of the second oil pipe 33 from hanging down The upward position of Nogata shifts, so as to influence the working effect of the product.For example, when on applied to locomotive, long-term Vibrations can usually cause above-mentioned this skew.

Turning now to Fig. 1 to Fig. 3, they show one embodiment according to tractive transformer of the present utility model.This The tractive transformer of utility model mainly includes：One fuel tank, 1, oil conservater 2 and one above in association with Fig. 4-5 as begged for The pipeline connecting parts 3 of opinion.One end extended from the bottom of housing 31 of first oil pipe 32 is connected to oil conservater 2, and the second oil One end extended from the top of housing 31 of pipe 33 is connected to fuel tank 1.

As described above, the utility model preferably uses integrated form oil conservater, i.e., oil conservater 2 is fixed on to the side wall of fuel tank 1, To reduce the volume of equipment and be easy to later maintenance., will be with therefore, because fuel tank 1 and oil conservater 2 are in a basic plane The top that upper combination Fig. 4 and the pipeline connecting parts 3 of Fig. 5 discussion are installed on oil conservater 2 can avoid structure in this integrated form The lower failure that air occurs and enters fuel tank 1.In the embodiment shown in fig. 1, above-mentioned one end of the first oil pipe 32 is from oil conservater 2 First open top (not shown) extend into oil conservater 2, and one on above-mentioned one end and fuel tank 1 of the second oil pipe 33 Connected between individual second open top via a conduit 4.In this embodiment, the first oil pipe 32 and the second oil pipe 33 can be equal It is rigid pipe, and conduit 4 can use flexible pipe.

In addition, for tractive transformer as described in Figure 1 is applied on the locomotive of such as high ferro, can further set A pair of mounting brackets 5.This is respectively arranged at two of the same above-mentioned side wall for being fixed with oil conservater 2 of fuel tank 1 vertically to mounting bracket 5 Side.The tractive transformer can be installed on using the mounting bracket 5 in the car body of locomotive, such as vehicle bottom, after facilitating Phase safeguards.

To sum up, the utility model proposes a kind of new pipeline connecting parts for tractive transformer, pipeline connection Part can guarantee that fluid all the time inside it, and can ensure that air can not enter in fuel tank easily, and is particularly suitable for use in and will integrate Oil conservater is integrated in the tractive transformer on fuel tank.In addition, this integrated oil conservater of the present utility model is integrated on fuel tank Tractive transformer also at least has the advantages of small volume, easy to maintenance.

Those skilled in the art can be obvious, and various modifications and change can be carried out to above-mentioned example embodiment of the present utility model Type is without departing from spirit and scope of the present utility model.Accordingly, it is intended to the utility model covering is set to fall in appended claims And its in the range of equivalent arrangements to modifications and variations of the present utility model.
