In addition, multiple groups of arc frames 1 are provided on a single group of support frames 2, so that the pipeline body 3 is placed more stably, and a valve 4 is provided on the pipeline body 3.

[0027] In one embodiment of the utility model, a moving assembly 5 is arranged on the outer side of the support frame 2, and the moving assembly 5 includes a long threaded column 51. The long threaded column 51 is fixedly installed on the outer side of one of the two adjacent groups of support frames 2, and the short threaded column 52 is fixedly installed on the outer side of the other group of support frames 2. The adjacent side walls of the long threaded column 51 and the short threaded column 52 are tightly fitted, and the outer sides of the long threaded column 51 and the short threaded column 52 are threadedly installed with a threaded sleeve 53. The two adjacent groups of pipe bodies 3 are fixedly connected. When the two groups of pipe bodies 3 are connected end to end, the threaded sleeve 53 is rotated so that the threaded sleeve 53 is located on the outer side of the long threaded column 51 and the short threaded column 52, so that the connection of the pipe body 3 is more stable. A U-shaped frame 54 is fixedly installed on the top of the support frame 2. The U-shaped frame 54 is located directly above the long threaded column 51. A thin rod 55 is slidably fitted inside the top of the U-shaped frame 54. A knob 56 is fixedly installed on the top of the thin rod 55. A thick rod 57 is slidably fitted inside the bottom end of the U-shaped frame 54. The arc-shaped outer wall of the thick rod 57 is tightly fitted inside the arc-shaped side wall of the long threaded column 51. A tight spring 58 is sleeved on the outside of the thin rod 55. The top of the tight spring 58 slides and fits the lower surface of the top of the U-shaped frame 54. The bottom of the tight spring 58 slides and fits the top of the thick rod 57. A flow meter body 59 is threadedly installed on the bottom end of the thick rod 57. The flow meter body 59 is located inside the pipeline body 3. The top of the thin rod 55 is rotatably installed with an instrument 7, a connected cavity is provided in the center of the thin rod 55 and the thick rod 57, and a wire is provided inside the cavity, and the meter 7 is electrically connected to the flow meter body 59 through the wire. When the flow meter body 59 needs to be replaced, the valve 4 is closed, and then the knob 56 is pulled up, thereby driving the thin rod 55 and the thick rod 57 to be pulled up synchronously, so that the flow meter body 59 is pulled out of the pipeline body 3, and at the same time, the spring 58 is pressed and deformed, and a clamping block 510 is fixedly installed on the outer side of the top of the thick rod 57. In addition, two groups of clamping blocks 510 are provided, and the two groups of clamping blocks 510 are symmetrically arranged at both ends of the thick rod 57. A fixing block 511 is fixedly installed inside the U-shaped frame 54, and a clamping groove 512 is provided on the fixing block 511. In addition, two groups of fixing blocks 511 and card slots 512 are provided, and the two groups of fixing blocks 511 and card slots 512 are symmetrically arranged at the front and rear ends of the U-shaped frame 54, and the card block 510 is located directly above the card slot 512, and the card block 510 and the card slot 512 are adapted in size. Then the knob 56 is rotated to make the card block 510 rotate synchronously, so that the card block 510 will pass over the fixing block 511 upward, and then the knob 56 is turned again to make the card block 510 fall into the card slot 512, so that it is convenient to fix its position after pulling up the flow meter body 59, and then the flow meter body 59 can be rotated to perform the replacement operation, so that a staff member can also more conveniently replace the flow meter body 59.

[0028] In one embodiment of the utility model, a sealing component 6 is provided on the inner side of the pipe body 3, a fixing ring 61 is fixedly installed inside the arc-shaped side wall at the top end of the pipe body 3, a sealing airbag 62 is fixedly installed inside the fixing ring 61, and the arc-shaped outer wall at the bottom end of the thick rod 57 is tightly fitted with the arc-shaped inner wall of the sealing airbag 62. Furthermore, when the flow meter body 59 is placed into the pipe body 3, the thick rod 57 will squeeze the sealing airbag 62 inside the fixing ring 61. In addition, a return spring 63 is fixedly installed inside the sealing airbag 62. There are ten groups of return springs 63, and the ten groups of return springs 63 are arranged in a circular array with equal spacing around the center of the circular cross-section of the fixing ring 61 as the center of the array, so as to achieve better sealing performance, thereby compressing and deforming the return spring 63, and cooperating with the elastic potential energy of the return spring 63 to make the thick rod 57 tightly fit the sealing airbag 62, so as to ensure that the movable component 5 is convenient for replacing the flow meter body 59 while ensuring sealing performance.

[0029] Working principle: When the two groups of pipe bodies 3 are connected end to end, the threaded sleeve 53 is rotated so that the threaded sleeve 53 is located outside the long threaded column 51 and the short threaded column 52, so that the pipe body 3 is connected more firmly. When the flow meter body 59 needs to be replaced, the valve 4 is closed, and then the knob 56 is pulled up, thereby driving the thin rod 55 and the thick rod 57 to be pulled up synchronously, so that the flow meter body 59 is pulled out of the pipe body 3, and the spring 58 is compressed and deformed at the same time, and then the knob 56 is rotated to make the block 510 rotate synchronously, so that the block 510 will pass over the fixed block 511 upwards, and then the knob 56 is rotated again to make the block 510 rotate synchronously. The block 510 falls into the card slot 512, so that after the flow meter body 59 is pulled up, its position can be fixed conveniently, and then the flow meter body 59 can be rotated to perform the replacement operation, so that a staff member can also more conveniently replace the flow meter body 59. Furthermore, when the flow meter body 59 is placed into the pipeline body 3, the thick rod 57 will squeeze the sealing air bag 62 on the inside of the fixing ring 61, so that the reset spring 63 is compressed and deformed, and the elastic potential energy of the reset spring 63 makes the thick rod 57 fit tightly with the sealing air bag 62, thereby ensuring that the movable component 5 is convenient for replacing the flow meter body 59 while ensuring the sealing.
