It is an instrument that uses numerical values to intuitively represent the measured flow rate and the total amount of fluid in a selected time interval. Flow meters are divided into differential pressure flow meters, rotor flow meters, throttling flow meters, slit flow meters, volumetric flow meters, electromagnetic flow meters, ultrasonic flow meters, etc. They are also divided into liquid flow meters and gas flow meters. Flow meters are widely used in various fields, especially in ensuring product quality, improving production efficiency, and promoting the development of science and technology.

However, in actual use, the turntable assembly is driven to rotate by the handwheel, and it needs to be rotated to a suitable angle so that the flange at one end of the air inlet pipe is at the same level as the flange of the corresponding pipe on the turntable assembly, and then the pipe on the turntable assembly is pushed. When the turntable assembly rotates, the rotation angle is not easy to grasp, and it is easy to rotate excessively, so that the flange at one end of the air inlet pipe cannot correspond to the flange at one end of the pipe on the turntable assembly, so that it cannot be connected with bolts, which is not conducive to actual use.

[0019] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.
[0020] Example 1
[0021] like Figure 1-Figure 5 As shown, the utility model provides a technical solution: it includes a mounting seat 1 and an air intake pipe 4, the top of the mounting seat 1 is fixedly connected to two bearing plates 3, the top of the bearing plates 3 are provided with mounting grooves 2, the air intake pipe 4 is arranged between the two mounting grooves 2, one side of the bearing plate 3 is fixedly connected to two side plates 23, a first roller 17 is rotatably connected between the two side plates 23, one side of the bearing plate 3 and above the first roller 17 are provided with two limiting assemblies, one end of the top of the mounting seat 1 is slidably connected to a moving rod 10, a card slot 24 is provided on the outside of the moving rod 10, the top of the moving rod 10 is fixedly connected to a cross plate 12, the outside of the moving rod 10 and between the mounting seat 1 and the cross plate 12 are sleeved with a second spring 11, the top of the cross plate 12 is slidably connected to an arc plate 16, and a clamping assembly is provided on the top of the inner side of the mounting seat 1, and the clamping assembly cooperates with the card slot 24 to fix the moving rod 10.
[0022] Through the above embodiment, when the flow meter is tested, the air inlet pipe 4 is first placed inside the two mounting grooves 2, and then the air inlet pipe 4 is fixed by two limit assemblies, and the arc plate 16 is pulled out, and then the pipe on the turntable assembly is driven to rotate by the hand wheel, as shown in FIG. Figure 2 As shown in the middle right position, after rotating to the approximate position, the cylinder is used to push the pipe on the rotating assembly to move, and then the turntable is rotated so that the flange at one end of the pipe on the turntable fits with the top of the arc plate 16, and the turntable is rotated to push the arc plate 16 down and compress the second spring 11. After being compressed to the maximum position, the top of the arc plate 16 and the lowest point of the flange at one end of the intake pipe 4 are in the same horizontal plane. At this time, the clamping assembly cooperates with the clamping groove 24 to fix the arc plate 16, and then the pipe on the turntable is pushed. At this time, the pipe on the turntable slides along the top of the arc plate 16, so as to guide and position the flange at one end of the intake pipe 4 and the flange of the pipe on the turntable, so as to avoid the problem of multiple adjustments caused by excessive rotation, thereby enhancing the practicality of the device.
[0023] Example 2
[0024] like Figure 1-Figure 5As shown, the top of the horizontal plate 12 is fixedly connected with a U-shaped rod 14, the outer side of the U-shaped rod 14 is slidably connected with a slider 15, and the top of the slider 15 is fixedly connected with the bottom of the arc plate 16. The clamping assembly includes a fixed plate 6, the fixed plate 6 is fixedly connected to the top of the inner side of the mounting seat 1, one side of the fixed plate 6 is slidably connected with a slide bar 7, one end of the slide bar 7 is fixedly connected with a clamping block 9, and a first spring 8 is sleeved on the outer side of the slide bar 7 and between the clamping block 9 and the fixed plate 6. One end of the clamping block 9 is provided with an inclined surface structure. The end of the slide bar 7 away from the clamping block 9 is fixedly connected with a pull handle 13. When the flange of the pipe on the turntable fits against the arc plate 16 and drives the arc plate 16 to move downward, the bottom of the moving rod 10 will conflict with the inclined surface of one end of the block 9, thereby pushing the block 9 to move and compressing the first spring 8. After the arc plate 16 moves to the maximum position, under the elastic force of the first spring 8, the block 9 is pushed to move, so that one end of the block 9 enters the interior of the slot 24, thereby fixing the moving rod 10, and by setting the slider 15, the arc plate 16 is limited to prevent it from detaching.
[0025] The limiting assembly includes a mounting plate 18, which is fixedly connected to one side of the bearing plate 3. The internal thread of the mounting plate 18 is connected to a threaded rod 20, one end of the threaded rod 20 is rotatably connected to a U-shaped plate 19, the inside of the U-shaped plate 19 is rotatably connected to a second roller 22, the first roller 17 and the second roller 22 are both in contact with the outer side of the air intake pipe 4, and a guide rod 21 is slidably connected to one side of the mounting plate 18, one end of the guide rod 21 is fixedly connected to one side of the U-shaped plate 19. By setting the limiting assembly, after the air intake pipe 4 is placed between the two mounting grooves 2, the threaded rod 20 is rotated, and the U-shaped plate 19 is limited to prevent rotation due to the rotation of the guide rod 21 and the mounting plate 18, thereby driving the second roller 22 to move so that the second roller 22 abuts against the outer side of the air intake pipe 4, and it is convenient to replace the air intake pipe 4 with different diameters.
[0026] A filter grid 5 is provided at one end of the air intake pipe 4. By providing the filter grid 5 inside the air intake pipe 4, larger impurities are filtered to prevent the air intake pipe 4 from being blocked.
[0027] Working principle: When testing the flow meter, first place the air inlet pipe 4 inside the two mounting grooves 2, then rotate the threaded rod 20. As the guide rod 21 and the mounting plate 18 rotate, the U-shaped plate 19 is limited to prevent rotation, thereby driving the second roller 22 to move so that the second roller 22 abuts against the outer side of the air inlet pipe 4; at the same time, pull out the arc plate 16, and then use the hand wheel to drive the pipe on the turntable assembly to rotate, such as Figure 2As shown in the middle right position, after rotating to the approximate position, the cylinder is used to push the pipe on the rotating assembly to move, and then the turntable is rotated so that the flange at one end of the pipe on the turntable fits with the top of the arc plate 16, and the turntable is rotated to push the arc plate 16 down and compress the second spring 11. After being compressed to the maximum position, the top of the arc plate 16 and the lowest point of the flange at one end of the intake pipe 4 are in the same horizontal plane, and when the arc plate 16 moves down, the bottom of the moving rod 10 will conflict with the inclined surface at one end of the block 9, thereby pushing the block 9 to move and compressing the first spring 8. After the arc plate 16 moves to the maximum position, at this time, under the elastic force of the first spring 8, the block 9 is pushed to move, so that one end of the block 9 enters the inside of the card slot 24, thereby fixing the moving rod 10, and then pushing the pipe on the turntable. At this time, the pipe on the turntable slides along the top of the arc plate 16, so that the flange at one end of the intake pipe 4 and the flange of the pipe on the turntable are accurately fitted, as shown in FIG. Figure 3 As shown in the figure, it is convenient to install the bolts.
