Detailed Description
In order to make the objects, technical solutions and advantages of the present invention clearer, the following will explain in detail each embodiment of the present invention with reference to the accompanying drawings. However, it will be appreciated by those of ordinary skill in the art that in various embodiments of the invention, numerous technical details are set forth in order to provide a better understanding of the present application. However, the technical solutions claimed in the claims of the present application can be implemented without these technical details and with various changes and modifications based on the following embodiments.
The first embodiment of the present invention relates to a pipe, as shown in fig. 1, the two ends of the pipe 1 are respectively a first pipe orifice end face 11 and a second pipe orifice end face 12, and the first pipe orifice end face 11 and the second pipe orifice end face 12 are annular inclined planes. The first nozzle end face 11 has an annular projection 13 in the axial direction of the first nozzle end face 11, and the second nozzle end face 12 has an annular groove 14 in the axial direction of the second nozzle end face 13.
It can be seen from the above that, when the pipeline 1 of the present embodiment is spliced with another pipeline 1, as shown in fig. 4, the first pipe orifice end face 11 of the pipeline 1 can be spliced with the second pipe orifice end face 12 of another pipeline 1, and the two pipe orifice end faces can be engaged with each other by the inclined design of the two pipe orifice end faces, and meanwhile, in the splicing process, the annular protrusion 13 on the first pipe orifice end face 11 of one pipeline 1 can be embedded in the annular groove 14 of the second pipe orifice end face 12 of another pipeline 1, so that the two pipelines 1 can achieve the purpose of automatic centering when being spliced, and further, the positioning tool can be omitted to perform operation on the two pipelines 1, thereby avoiding the interference of the positioning tool on the welding operation area, and enabling the weld formed when the two pipelines 1 are welded to be formed at one time, thereby not only improving the integrity of the weld, but also enables the weld to have higher strength and sealing performance.
Specifically, in the present embodiment, as shown in fig. 1 and 2, the annular projection 13 on each first nozzle end face 11 includes: an inner side surface 131 and an outer side surface 132 provided around the axial direction of the first nozzle end surface 11, and an upper surface 133 connecting the inner side surface 131 and the outer side surface 132, and the upper surface 133 and the nozzle end surface 11 are opposed to each other in the axial direction of the first nozzle end surface 11. Next, in the present embodiment, as shown in fig. 1 and 3, the corresponding annular groove 14 includes: a first groove wall 141 and a second groove wall 142 arranged around the axial direction of the second nozzle end surface 12, a groove bottom 143 connecting the first groove wall 141 and the second groove wall 142, and a notch 144 opposed to the groove bottom 143 in the axial direction of the second nozzle end surface 12.
It can be seen that, when the two pipes 1 are spliced, the inner side 131, the outer side 132 and the upper surface 133 of the annular protrusion 13 on the first pipe orifice end surface 11 of one pipe 1 can be respectively fitted with the first groove wall 141, the second groove wall 142 and the groove bottom 143 of the annular groove 14 on the second pipe orifice end surface 12 of the other pipe 1, that is, in the present embodiment, the shape of the annular protrusion 13 is the same as that of the annular groove 14, so that the accuracy of centering of the two pipes 1 can be further improved.
Also, it is worth mentioning that in the present embodiment, as shown in fig. 1, the upper surface 133 of the annular protrusion 13 on the first nozzle end surface 11 is formed to extend along the inclined direction of the first nozzle end surface 11, and the groove bottom 143 of the annular groove 14 on the second nozzle end surface 12 is formed to extend along the inclined direction of the second nozzle end surface 12, that is, in the present embodiment, the upper surface 133 of the annular protrusion 13 and the groove bottom 143 of the annular groove 14 are both designed to be inclined surfaces, so that the upper surface 133 and the groove bottom 143 can be respectively disposed in parallel with the first nozzle end surface 11 and the second nozzle end surface 12. Therefore, when the two pipes 1 are spliced, the guiding performance of the two pipes 1 at the time of splicing can be further improved by means of the slope design of the upper surface 133 of the annular protrusion 13 and the groove bottom 143 of the annular groove 14.
In addition, in the present embodiment, preferably, the portions of the second nozzle end surface 12 of the annular groove 14, which are connected to the inner groove wall 141 and the outer groove wall 142 of the annular groove 14, are arc-surface transitions. Similarly, the upper surface 133 of the annular protrusion 13 is connected to the inner side surface 131 and the outer side surface 132 by a curved transition. Therefore, when the two pipelines 1 are spliced with each other, the guide performance of the two pipelines 1 can be further improved by matching the arc surfaces at the two ends of the upper surface 133 of the annular protrusion 13 with the arc surfaces at the two ends of the groove bottom 143 of the annular groove 14.
Meanwhile, in the present embodiment, as shown in fig. 5, the inner side surface 131 and the outer side surface 132 of the annular protrusion 13 are formed to extend obliquely in the axial direction of the first nozzle end surface 11, that is, in the present embodiment, both the inner side surface 131 and the outer side surface 132 of the annular protrusion 13 are annular inclined surfaces, and in the present embodiment, the inclination directions of the inner side surface 131 and the outer side surface 132 are opposite. Likewise, the inner groove wall 141 and the outer groove wall 142 of the annular groove 14 extend obliquely in the axial direction of the second nozzle end surface 12, that is, in the present embodiment, the inner groove wall 141 and the outer groove wall 142 of the annular groove 14 are another annular inclined surface, and in the present embodiment, the oblique directions of the inner groove wall 141 and the outer groove wall 142 are opposite. Thus, when two pipes 1 are spliced, the guiding performance of the two pipes 1 can be further improved by the inclined surface design of the inner side surface 131 and the outer side surface 132 of the annular protrusion 13 and the inner groove wall 141 and the outer groove wall 142 of the annular groove 14. It should be noted, however, that the outer side 132 and the inner side 131 of the annular protrusion 13, and the inner groove wall 141 and the outer groove wall 142 of the annular groove 14 in this embodiment may have the same inclination direction.
In addition, it should be mentioned that, in the present embodiment, the upper surface 133 of the annular protrusion 13 and the groove bottom 134 of the annular groove 14 may be both a tooth surface, so that when the two pipes 1 are spliced, the upper surface 133 of the annular protrusion 13 of one pipe 1 and the groove bottom 143 of the annular groove 14 of the other pipe 1 may be engaged with each other, thereby preventing the two pipes 1 from deflecting when the spliced portion of the two pipes 1 is welded, and thus further improving the quality of the weld joint.
Further, as a preferable mode, in the present embodiment, as shown in fig. 4, both the upper surface 133 of the annular projection 13 and the groove bottom 143 of the annular groove 14 are magnetized magnetic sides. Moreover, the polarity of the upper surface 133 of the annular protrusion 13 is opposite to that of the groove bottom 143 of the annular groove 14, so that after the two pipelines 1 are spliced, the upper surface 133 of the annular protrusion 13 of any one pipeline 1 can be mutually attracted with the groove bottom 143 of the annular groove 14 of the other pipeline 1, the effect of fixing the two pipelines 1 is achieved, the phenomenon that the two pipelines 1 shake when the splicing parts of the two pipelines 1 are welded is avoided, and the quality of a welding seam after welding at the joint of the two pipelines 1 is further improved.
A second embodiment of the present invention relates to a pipe assembly, as shown in fig. 6, including: at least two pipes 1 as described in the first embodiment, the first nozzle end surface 11 of any one pipe 1 is connected with the second nozzle end surface 12 of another pipe 1 by welding. And, in two pipelines 1 welded with each other, the annular protrusion 13 of one pipeline 1 is embedded in the annular groove 14 of the other pipeline 1.
It can be seen from the above that, since the first pipe orifice end face 11 and the second pipe orifice end face 12 of the pipes 1 are both annular inclined planes, and the first pipe orifice end face 11 has the annular protrusion 13, and the second pipe orifice end face 12 has the annular groove 14, when the two pipes 1 are spliced, the first pipe orifice end face 11 of one pipe 1 can be fitted with the second pipe orifice end face 12 of the other pipe 1, and the annular protrusion 12 on the first pipe orifice end face 11 of one pipe 1 can be embedded in the annular groove 14 of the second pipe orifice end face 12 of the other pipe during the splicing process, so that the two pipes 1 can be spliced automatically, thereby eliminating the use of a positioning tool to perform centering operation on the two pipes 1, avoiding the interference of the positioning tool to a welding operation area, and enabling a weld formed during welding of the two pipes 1 to be formed at one time, therefore, the integrity of the welding seam is improved, and the welding seam can have higher strength and sealing performance.
In the present embodiment, as shown in fig. 6, both the two pipes 1 welded to each other may be straight pipes, or as shown in fig. 7, both may be bent pipes. Alternatively, as shown in fig. 8, one of the two pipes 1 welded to each other is a bent pipe, and the other pipe 1 is a straight pipe.
A third embodiment of the present invention relates to a pipe system comprising at least one pipe assembly as described in the first embodiment.
It will be understood by those skilled in the art that the foregoing embodiments are specific examples of the invention, and that various changes in form and details may be made therein without departing from the spirit and scope of the invention in its practical application.
