As background art, a diesel engine pipeline for transmitting a medium in a diesel engine has a complex structure, a variable size, and a high manufacturing difficulty, and when a plurality of pipelines are connected, the pipelines are usually fixed by flanges fixed to the pipelines. However, the size deviation between the pipes is difficult to avoid due to the limitation of the manufacturing process, and the deviation is difficult to deal with during the assembly and installation on site, so the whole manufactured pipe is often required to be adjusted, even directly scrapped and then manufactured again. This not only increases the number of man-hours, but also increases the cost.

In addition, the connection mode between the pipeline and the flange is single, the flange is usually fixed on the pipeline in a welding or integral casting mode, the angle of the flange cannot be adjusted due to the connection mode, when the pipelines are not positioned on the same horizontal line, a new bent pipeline needs to be additionally arranged to realize connection between the pipelines, the cost is increased, and the sealing difficulty is also increased.

It is therefore necessary to provide a diesel engine pipe which can be easily adjusted for dimensional deviations to ensure a reliable connection of the diesel engine pipe to external components.

For the purpose of illustration, the drawings show only the structures associated with embodiments of the invention.

Fig. 1 shows a schematic structural diagram of a diesel engine pipeline 100 according to an embodiment of the present invention.

Referring to fig. 1, an embodiment of the present invention provides a diesel engine pipeline 100, which includes a pipe body 110 and a first flange 120. The tube body 110 is formed with a groove 111, and the groove 111 extends along a circumferential direction of the tube body 110. The first flange 120 is at least partially received in the recess 111. Wherein the first flange 120 is configured to be rotatable about an axial direction of the pipe body 110 with respect to the pipe body 110 by means of the groove 111.

The utility model provides a diesel engine pipeline 100, through the first recess 111 of seting up on body 110, can carry out the axial spacing to first flange 120, first flange 120 is through the rotation around the axis direction of body 110, when can have the deviation on the circumference installation dimension, with the help of the rotatory butt joint position of adjusting of first flange 120 to ensure that body 110 can be connected with the external component reliably.

The external component may be another diesel engine pipe 100, or may be another component inside the diesel engine, which is not limited herein.

In some embodiments, the tube 110 defines a plurality of grooves 111, and the first flange 120 includes a plurality of grooves. All the grooves 111 are arranged spaced apart from each other in the axial direction. Each first flange 120 is disposed in a corresponding one of the grooves 111. In this way, the plurality of first flanges 120 can facilitate connection of the diesel engine duct 100 to external components at different positions of the pipe body 110, and on the one hand, can improve the applicability of the diesel engine duct 100, and on the other hand, can ensure the connection reliability of the pipe body 110. And the grooves 111 corresponding to the first flanges 120 ensure that each first flange 120 can rotate about the axial direction of the pipe body 110, so that it is easy for each first flange 120 to adjust the docking position to ensure the reliability of the connection of the diesel engine with the external part. In the embodiment shown in fig. 1, the pipe body 110 defines two grooves 111, and the first flange 120 includes two flanges (one of the first flanges 120 is not shown). Further, the first flange 120 includes a body 121 and a positioning portion 122 movably connected to the body 121. The outline shape of at least part of the positioning portion 122 is matched with the inner outline shape of the groove 111. As such, the first flange 120 can be mated with the groove 111 by means of the positioning portion 122.

In some embodiments, the groove 111 is annularly disposed. Thus, the rotation angle of the first flange 120 relative to the pipe body 110 can be maximized by the annular groove 111, so that the first flange 120 is prevented from being blocked by the groove wall of the groove 111 in the rotation process, and the first flange is blocked or is difficult to rotate. In still other embodiments, the grooves 111 may be disposed in an arc. The inventor has found that in some embodiments, the pipe body 110 is provided with a through hole 113 for an external component to extend into, so as to achieve communication between the diesel engine pipe 100 and the pipe of the external component. The external component includes, but is not limited to, a bellows or a metal pipe. When the outer part is a metal pipe, sealing between the pipes is achieved by means of an outer seal. At this time, when the first flange 120 rotates around the axial direction of the pipe body 110, only circumferential fine adjustment of the first flange 120 needs to be realized, and dimensional deviation between the pipes is solved. Through being the arc with recess 111 setting, can reduce the technology loss when guaranteeing that first flange 120 satisfies rotatory demand, can also promote the intensity of body 110 in addition.

Fig. 2 shows a schematic structural diagram of the adjusting member 130 in an embodiment of the present invention.

Referring to fig. 1 and 2, in some embodiments, the diesel engine pipe 100 further includes an adjusting member 130, and one end of the adjusting member 130 is used to connect to an external component. The other end of the adjusting member 130 is movably connected to the first flange 120 to adjust the distance between the first flange 120 and the external member. In this way, on the one hand, when there is a dimensional deviation of the spacing between the external member and the diesel engine pipe 100, it is possible to adjust by the adjusting member 130. On the other hand, when different connection space requirements exist between the external component and the diesel engine pipe 100, the adjustment part 130 can be used for adaptive adjustment, so that the universality of the diesel engine pipe 100 is improved. In combination with some of the aforementioned embodiments, the adjusting element 130 is sleeved on the positioning portion 122 of the first flange 120. In this way, the body 121 can perform the movement of the relative positioning portion 122 by means of the adjusting piece 130, thereby adjusting the distance between the body 121 and the external part.

In some embodiments, the first flange 120 defines an adjustment hole, and the adjustment member 130 is screwed to a hole wall of the adjustment hole. Wherein, regulating part 130 can rotate relative to the pore wall of regulation hole to the degree of depth that regulating part 130 stretched into the regulation hole is adjusted. In this manner, the threaded connection can convert the rotation of the adjusting member 130 into a linear motion, thereby achieving the adjustment of the interval. Moreover, the threaded connection can enhance the positioning capability of the adjustment member 130, ensuring that the adjustment member 130 can maintain an adjusted spacing. In combination with the above embodiments, the body 121 is provided with an adjusting hole. Further, two adjusting holes are formed in the body 121, and the two adjusting holes are arranged at intervals along the radial direction of the body 121. Specifically, in some embodiments, the diesel engine conduit 100 further comprises a fastener 140, and the fastener 140 is threadedly coupled to the adjustment member 130. In this way, the adjusting member 130 can be further locked by the fastening member 140, so that the phenomenon that the adjusting member 130 is loosened due to vibration and the like between the pipes to cause connection failure between the pipes is avoided. In particular to the present embodiment, the fastener 140 includes a bolt assembly. In combination with the above embodiments, the adjusting member 130 may be connected to the positioning portion 122, or the fastening member 140 may be disposed through the adjusting member 130 to connect to the positioning portion 122. The positioning portion 122 is located in the groove 111 to provide positioning support for the movement of the body 121 relative to the tube 110, and is not limited herein.

In some embodiments, the diesel engine conduit 100 further comprises a second flange 150. The tube 110 has a joint 112 with a first opening, and the second flange 150 is connected to the joint 112 and communicates with the first opening. The second flange 150 has a first surface 151 perpendicular to the first direction. The first surface 151 is provided with a first engaging groove 152, and the first engaging groove 152 is used for engaging with an external sealing element. The first direction is perpendicular to the axial direction. Thus, a placing space can be provided for the external sealing element through the first clamping groove 152, so that the sealing effect after the diesel engine pipeline 100 is connected with the external part is improved. Further, a second engaging groove 153 is further formed in the first surface 151, and the second engaging groove 153 is used for engaging with an external sealing element. The first card slot 152 is disposed around the second card slot 153. So, encircle the setting of second draw-in groove 153 through first draw-in groove 152, can promote the sealed effect after diesel engine pipeline 100 connects through two-layer external seal spare. Moreover, because diesel engine pipeline 100 is when the transmission medium, for example, the medium such as coolant can corrode body 110 and second flange 150, through two-layer draw-in groove, can be behind medium corruption second draw-in groove 153, first draw-in groove 152 in addition is as sealed guarantee, avoids appearing corroding and reveals.

Fig. 3 shows a schematic structure of the corrosion-resistant layer 160 in an embodiment of the present invention.

As shown in fig. 3, in some embodiments, a corrosion resistant layer 160 is disposed on the first surface 151. Therefore, the corrosion-resistant effect of the second flange 150 can be improved, and the diesel engine pipeline 100 and the external part are ensured not to be corroded by the second flange 150, so that leakage occurs, and equipment is even stopped.

The inventor has found that when the diesel engine pipe 100 is assembled into a diesel engine, vibration of the whole diesel engine cannot be avoided, and although the vibration of the diesel engine pipe 100 is small, the connection part between the second flange 150 and the pipe body 110 inevitably has problems of loosening, leakage and the like as the operation time of the diesel engine goes on. Meanwhile, a medium, such as a coolant, transmitted by the diesel engine pipe 100 has certain corrosiveness, and leakage often occurs at the joint 112 between the second flange 150 and the pipe body 110 under the working condition of superposition of vibration and corrosion. In this regard, in some embodiments, the second flange 150 is a unitary structure with the joint 112. Therefore, the second flange 150 and the joint 112 in the integrated structure are compact in structure and few in assembly links, a mechanical connection mode and a sealing treatment means do not need to be considered, and the stability and the sealing performance of the connection strength are ensured.

Based on the same inventive concept, the utility model also provides a diesel engine, including above-mentioned diesel engine pipeline 100. By using the diesel engine pipeline 100, the whole assembly easiness of the diesel engine is improved, and the installation deviation existing when the diesel engine pipeline 100 is connected with an external part is solved. Because the cooling system in the diesel engine belongs to multi-cylinder reciprocating power machinery, the vibration of the whole engine cannot be avoided during operation. By solving the installation deviation between the diesel engine pipeline 100 and the external part, on one hand, the problem of loosening or leakage between the diesel engine pipeline 100 and the external part caused by the installation deviation and the vibration of the whole machine when subsequent equipment runs is avoided. On the other hand, the problem that the diesel engine duct 100 cannot be installed due to installation deviation and needs to be adjusted or remanufactured is avoided. And the corrosion resistance of the diesel engine pipeline 100 is improved, and leakage of transmission media of the diesel engine pipeline 100 is avoided, so that the normal operation of the diesel engine is ensured, and equipment halt caused by outflow of the media is avoided.

According to the diesel engine pipeline 100 and the diesel engine provided by the embodiment of the application, the first groove 111 formed in the pipe body 110 can axially limit the first flange 120, the first flange 120 rotates around the axis direction of the pipe body 110, and when deviation exists in the circumferential installation dimension, the butt joint position can be adjusted by means of rotation of the first flange 120, so that the pipe body 110 can be reliably connected with an external part. First draw-in groove 152 and second draw-in groove 153 have been seted up on the second flange 150 in the diesel engine pipeline 100, can promote the sealed effect after the diesel engine pipeline 100 is connected through two-layer external seal spare, can corrode second draw-in groove 153 back at the medium in addition, first draw-in groove 152 is as sealed guarantee in addition, avoids appearing corroding revealing. In addition, the first surface 151 of the second flange 150 is provided with a corrosion-resistant layer 160, so that the corrosion-resistant effect of the diesel engine pipe 100 is further improved.
