Description
Technical field
The utility model relates to the pipe diameter conversion part, refers in particular to the pipe diameter conversion part that has between the different-diameter pipeline.
Background technique
The pipe diameter conversion part is used to connect the pipeline with different-diameter, makes the pipeline of two different-diameters can form path.As shown in Figure 1, put down in writing a kind of air interchanger among the Chinese patent CN3441343, be installed between ceiling board 1000 and the roof, the joint 11 that its exhaust outlet place 10 is provided with is connected with exhaust duct 12, and indoor air is discharged to outdoor by exhaust duct 12.The joint 11 of such a air interchanger, be to design again after estimating the diameter of two coupled pipelines in advance, larger-diameter second cylinder 22 that has of having with corresponding exhaust outlet 10 than first cylinder 21 of minor diameter and corresponding exhaust duct 12, and with first cylinder 21, connecting plate 23 that second cylinder 22 is vertical.Because first cylinder 21 and second cylinder 22 are to be provided with one heart, therefore stress all concentrate on vertical connecting plate 23 on, so the joint of connecting plate 23 and first cylinder 21 and second cylinder 22 just is easy to be damaged, be difficult to the firm connection reliably that reaches permanent.Especially be law and the regulations that corresponding air interchanger is installed different areas, and the narrow and small especially place of some installing space, just relatively more difficult when the joint of air interchanger is connected with the pipeline different with its diameter.
The model utility content
Main purpose of the present utility model is to provide a kind of more easy-on pipe diameter conversion part.
Secondary objective of the present utility model is to provide a kind of firmer pipe diameter conversion part.
For achieving the above object, the utility model provides a kind of pipe diameter conversion part, comprise first cylinder with less first diameter, second cylinder with bigger second diameter, between described first cylinder and described second cylinder, be provided with the joint of circular cone tubular, on this joint, be provided with the some reinforcing parts that connect first cylinder and second cylinder, and the central shaft of the central shaft of first cylinder and second cylinder interlaces.
The outer wall of described joint is provided with some reinforcing parts, is radial setting since the circumferential part of first cylinder.
The inwall of described joint is provided with some reinforcing parts, is radial setting since the circumferential part of first cylinder, and extends on second cylinder inner wall.
Described joint is long more to the distance of the circumference of second cylinder from the circumference of first cylinder, and the interval between reinforcing part and the reinforcing part is more little.
Described reinforcing part is positioned at outside the inboard scope of first barrel bore.
Described first cylinder and described second cylinder have a common bottom surface.
The pipe diameter conversion part is injection molded by resin.
Advantage of the present utility model is to have the intensity of better installation adaptability and Geng Gao.

Embodiment
Fig. 2 is the utility model first embodiment's schematic representation.As shown in Figure 2, be installed in the space that ceiling board 1000 and roof form for a kind of, be used to connect the pipe diameter conversion part 100 of air interchanger and blast device, its have less first diameter first cylinder 110, have second cylinder 120 of bigger second diameter, and the joint 130 that is provided with the circular cone tubular between first cylinder 110 and second cylinder 120, and the central shaft 121 of the central shaft 111 of first cylinder 110 and second cylinder 120 interlaces.
As shown in Figure 2, first cylinder 110 be arranged on ventilation and the joint 30 of air-supply on the machine is connected, the pipeline 40 different with the diameter of this joint 30 is connected with second cylinder 120.And, because second cylinder 120 departs from the central shaft of first cylinder 110, therefore when installing pipeline, can be arranged on higher position to pipeline, thereby prevent bottom surface 400 and ceiling board interference.Therefore, has better installation adaptability than known technology.
In addition, because joint 130 is the circular cone tubular, and be provided with the some reinforcing parts that connect above-mentioned first cylinder and second cylinder, therefore when the pipeline 40 of second diameter is connected on the pipe diameter converting member 100, the weight of the pipeline 40 that second cylinder 120 bears has all been born by pipe diameter converting member 100, the stress that the circumference of second cylinder 120 bears is passed to first cylinder 110 equably, is absorbed by the repulsion of the centrifugal direction of first cylinder 110.By said structure, can increase the intensity of pipe diameter converting member 100.As mentioned above, because under the identical situation of the thickness of pipeline, can make the repulsion of the centrifugal direction of the little end of diameter become big, so as this mode of execution, the stress that the circumference of second cylinder 120 is subjected to is passed between less first cylinder, 110 sides of the diameter of joint 130, and it can be absorbed by the repulsion of its centrifugal direction more effectively.
Fig. 3 is the utility model second embodiment's schematic representation.On the outer wall of joint 130, be provided with some reinforcing parts 300.Be radial setting since the circumferential part 112 of first cylinder 110.Reinforcing part 300 makes joint 130 firmer.That is to say that reinforcing part 300 is arranged on the joint 130, second cylinder 120 is passed to first cylinder because of being connected the stress that is born with pipeline, can guarantee its intensity.Particularly, under reinforcing part 300 was arranged on situation on the outer wall, in work progress at the scene, when joint 130 was subjected to the bump in the outside, reinforcing part 300 can be protected.
Fig. 4 A and Fig. 4 B are the utility model the 3rd embodiment's sectional view and side schematic views.As shown in the drawing, the inwall 132 that is radial joint 130 since the circumferential part 112 of first cylinder 110 is provided with some reinforcing parts 300, and extends on second cylinder, 120 inwalls 122.Between reinforcing part and the reinforcing part, along with the circumference of first cylinder 110 is long more to the distance L of the circumference of second cylinder 120, the interval m between reinforcing part 300 and the reinforcing part 300 is more little.In order to prevent to influence the air flows in the pipeline, reinforcing part 300 is positioned at outside the inboard scope of first cylinder, 110 internal diameters.
Again as shown in the figure, in the present embodiment, in order farthest to adapt to narrow and small installing space, the bottom surface of first cylinder 110 and second cylinder 120 is on same, form a common bottom surface, can make the pipeline (not shown) of second diameter reach higher bottom surface 400 like this.
Whole pipe diameter conversion part 100 is injection molded by resin.By the injection molded pipe diameter converting member of resin, owing to have certain elastic force effect, can be thinner, lighter and can improve its elasticity, and, the effect of the reinforcing part by being arranged on joint makes to connect to be more prone to carry out and can improve the sealing of connection.
Above embodiment only is an a part of example of the present utility model.The utility model can be applied in different Environmental Conditions, as other fluid pipelines or major repair pipeline or the like.
