[0001] The utility model relates to the technical field of pipelines, in particular to a low-resistance U-shaped pipe. Background Art

[0002] U-tubes are usually used in fluid transmission systems, such as pipeline systems, water conservancy projects, etc. U-tubes are a special shape of pipes that look like the letter "U".

[0003] The design of the U-tube can reduce the friction resistance caused by the bend of the fluid in the pipeline, because the fluid does not need to undergo sudden changes in direction when moving in the U-tube, and the movement is relatively gentle, thereby reducing resistance losses and improving the efficiency of fluid transmission.

[0004] However, the distance between the two interfaces of the existing U-shaped tube cannot be adjusted. When the U-shaped tube needs to be installed between two other pipes, if the distance between the two other pipes does not match the distance between the two interfaces of the U-shaped tube, the staff needs to replace the U-shaped tube with another model, which brings inconvenience to the staff. Moreover, after a period of use, impurities will accumulate and adhere to the inner wall of the U-shaped tube, thereby increasing the resistance of fluid transmission and even causing blockage. The existing U-shaped tube is not easy to clean its inner wall. For this reason, we propose a low-resistance U-shaped tube. Utility Model Content

[0033] In this embodiment, two J-shaped tubes 1 and a stainless steel corrugated hose 9 installed between the two J-shaped tubes 1 together form a U-shaped tube. Before the U-shaped tube is installed on two other adjacent pipes, the distance between the two J-shaped tubes 1 can be adjusted according to the spacing between the two other adjacent pipes. The specific operation method is: first, pull the pull block 14 forward, the pull block 14 will drive the plug post 15 to slide forward in the inner wall of the cylindrical tube 13 and the connecting column 1 5, the plug post 15 will drive the ring 16 to slide forward in the cylindrical tube 13 (in this process, the spring 17 between the ring 16 and the cylindrical tube 13 will be squeezed on the outer wall of the plug post 15), and the plug post 15 will also slide forward in a socket 12 on the corresponding connecting column 2 6 until the plug post 15 completely slides away from the socket 12. While the movable pull block 14 is not released, the two J-shaped tubes 1 move away from each other, and the connecting column 2 6 will slide outward in the column groove 19 on the connecting column 1 5 (in this process, the slider 18 on the connecting column 2 6 will slide outward in the slide groove 20 on the column groove 19), and the annular plates 1 7 on each of the two J-shaped tubes 1 will move away from each other, and the two annular plates 1 7 will drive the corresponding annular plates 2 8 to move away from each other, and the stainless steel corrugated hose 9 between the two annular plates 2 8 will be stretched until the two J-shaped tubes 1 move to the required position, and then the pull block 14 is released. Under the action of the spring 17, the plug 15 will automatically insert into the other plug hole 12 on the connecting column 2 6, and the connecting column 2 6 and the connecting column 1 5 can be fixed again, and the distance between the two J-shaped tubes 1 is extended. Similarly, the distance between the two J-shaped tubes 1 can be shortened by moving the two J-shaped tubes 1 in the opposite direction according to the same operation (the stainless steel corrugated hose 9 can be squeezed and shortened accordingly), and the operation is simple.

[0034] Example 2: Please refer to Figure 1This embodiment further explains Example 1. The fixing assembly in the figure includes a plurality of bolts 10. The plurality of bolts 10 are slidably inserted into the inner walls of the annular plate 2 8 and the annular plate 1 7 around the central annular array of the annular plate 2 8, and the outer walls of the plurality of bolts 10 are all threaded with screw sleeves 11, and the plurality of screw sleeves 11 are all tightly fitted with the side walls of the annular plate 1 7.

The annular groove 22 is provided on the side wall of the annular plate 8 corresponding to the annular plate 7. The rubber ring 21 fits tightly in the annular groove 22. Specifically, the setting of the rubber ring 21 and the annular groove 22 can ensure good sealing between the annular plate 7 and the annular plate 28.

[0036] In this embodiment, when the stainless steel corrugated hose 9 and the two J-shaped tubes 1 need to be cleaned or the stainless steel corrugated hose 9 needs to be replaced, the multiple threaded sleeves 11 can be completely turned away from the corresponding bolts 10 in turn, and then the multiple bolts 10 can be pulled out from the inner walls of the corresponding annular plates 1 7 and 8 in turn, so that the two annular plates 2 8 can be separated from the corresponding annular plates 1 7, and the stainless steel corrugated hose 9 can be removed from between the two J-shaped tubes 1, and then the stainless steel corrugated hose 9 and the two J-shaped tubes 1 can be cleaned. When the cleaning is completed or the new stainless steel corrugated hose 9 is replaced, the stainless steel corrugated hose 9 can be installed and fixed between the two J-shaped tubes 1 according to the reverse operation, and the disassembly and assembly are simple.
