Description

Displaceable elbow structure with drainage device

Technical Field

The utility model relates to a steam directly buries the technical field of the part of pipeline, especially relates to a but displacement formula area hydrophobic means return bend structure.

Background

The drainage device is a main part of the steam buried pipeline, and the drainage device can discharge condensed water in the pipeline in time according to the operation condition, and is directly related to the safe operation of the steam buried pipeline. Because:

firstly, because the existing elbow with the drainage device is provided with a water collecting barrel, the length of the existing elbow is often larger than the size of a directly-buried pipe sleeve, and a hole needs to be formed in the sleeve to be used as a base of the water collecting barrel;

the water collecting barrel and the core pipe have thermal displacement together, so the elbow with the water drainage device can only be installed beside the fixed support generally (the water collecting barrel and the core pipe have thermal displacement together, so that the lower part of the water collecting barrel and the drainage pipe are jacked on the sleeve, and the water collecting barrel and the drainage pipe are damaged);

at present, the heat supply network pipelines are mostly compensated by rotary compensators when being arranged, if a section of directly-buried pipeline is arranged in the middle, the directly-buried pipeline is a low point, the pipeline lifting requires a water drainage device, namely the water drainage device is required to be arranged at a place with large thermal displacement, and the contradiction is generated between the requirements.

Disclosure of Invention

The utility model aims at overcoming the not enough of existence among the prior art, provide a but guarantee drainage device reliable drainage and can heat displacement take drainage device return bend.

The utility model provides a but displacement area hydrophobic means return bend structure which characterized by: comprises a tee joint, a core pipe, a water collecting bucket and an elbow;

wherein the core tubes comprise a first core tube which is vertically arranged and a second core tube which is horizontally arranged,

two ends of a horizontal joint of the tee joint are respectively connected with the first core pipe and the elbow, a vertical joint of the tee joint is communicated and connected with the water collecting barrel, and the elbow is connected with the second core pipe in the vertical direction;

a large outer sleeve is arranged outside the tee joint, the water collecting barrel and the first core pipe,

the large outer sleeve comprises a vertical pipe and a horizontal pipe which are vertically connected, and the first core pipe extends out of the outer end face of the vertical pipe;

a small outer sleeve is sleeved in the middle of the second core pipe, and the horizontal pipes of the small outer sleeve and the large outer sleeve are connected through an eccentric reducer;

still be provided with the drain pipe in the overcoat pipe, the pipeline of the vertical direction of drain pipe is parallel with first core pipe, and drain pipe one end stretches out in the outer terminal surface of vertical pipe, and the drain pipe other end is drawn forth in the water catch bowl.

Further, the elbow is positioned at the connecting corner of the vertical pipe and the horizontal pipe.

The beneficial effects of the utility model reside in that:

the structure is ingenious and reasonable, the center of the large sleeve is lowered by utilizing the eccentric reducer, the large sleeve can just hold a water collecting barrel, the water collecting barrel sleeve does not need to be made on the sleeve, irregular right-angle surfaces are reduced, the anticorrosion construction is convenient, a longer displacement space is provided, a certain displacement space is provided in the vertical ground outlet direction of the elbow due to the amplification reason of the sleeve, and therefore the core pipe and the drain pipe can be reliably thermally expanded when the pipeline runs.

Detailed Description

The invention is further described with reference to the following specific drawings and examples.

As shown in fig. 1-2:

the utility model provides a but displacement area hydrophobic means return bend structure which characterized by: comprises a tee joint 5, a core pipe 1, a water collecting bucket 6 and an elbow 8;

wherein the core tubes comprise a first core tube 1.1 placed vertically and a second core tube 1.2 placed horizontally,

two ends of a horizontal joint of the tee joint 5 are respectively connected with a first core pipe 1.1 and an elbow 8, a vertical joint of the tee joint is communicated with a water collecting barrel 6, and the elbow 8 is connected with a second core pipe 1.2 in the vertical direction;

a tee joint 5, a water collecting barrel 6 and a large outer sleeve 4 are communicated with the outside of the first core pipe 1.1,

the large outer sleeve 4 comprises a vertical pipe 4.1 and a horizontal pipe 4.2 which are vertically connected, and the first core pipe 1.1 extends out of the outer end face of the vertical pipe 4.1;

a small outer sleeve 2 is sleeved in the middle of the second core pipe, and the horizontal pipes 4.2 of the small outer sleeve and the large outer sleeve are connected through an eccentric reducer 3;

still be provided with drain pipe 7 in the overcoat pipe, the pipeline of the vertical direction of drain pipe 7 is parallel with first core pipe 1.1, and drain pipe one end stretches out in the outer terminal surface of vertical pipe 4.1, and the drain pipe other end is drawn forth in water-collecting bucket 6.

The elbow 8 is positioned at the connecting corner of the vertical pipe 4.1 and the horizontal pipe 4.2.

Since the water collection tub 6 is inside the large casing 4,

the conventional drainage elbow uses a conventional reducer, the space at the lower part of the elbow can only accommodate the position of a drainage pipe, the displacement space is limited, and the water collecting barrel needs to be provided with a hole as a sleeve. The structure adopts the eccentric reducer to enlarge the space at the lower part of the elbow and partially enlarge the elbow casing pipe, as shown in the dotted line frame part in figure 1, so that the displaceable elbow pipe with the drainage device has larger displacement space and can be applied to the place with the drainage device, which is displaced in the buried pipeline and needs to go out of the ground.

Finally, it should be noted that the above embodiments are only used for illustrating the technical solutions of the present invention and not for limiting, and although the present invention has been described in detail with reference to the examples, those skilled in the art should understand that the technical solutions of the present invention can be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should be covered by the scope of the claims of the present invention.
