[0022] like Figures 1 to 4 As shown, a gas flow meter sealing measuring device comprises a water storage bin 1 and an air pump 7, wherein two moving blocks 4 are slidably connected to the inner wall surface of the water storage bin 1, a cushion block 5 is bonded to the adjacent wall surface of the two moving blocks 4, a sealing gasket 6 for sealing both ends of the gas flow meter is fixedly connected to the outer wall surface of the cushion block 5, an air guide hose 8 is connected to the output end of the air pump 7, a transverse cavity for the movable end of the air guide hose 8 to pass through is provided on the moving block 4, the cushion block 5 and the sealing gasket 6 arranged on the left side of the inner cavity of the water storage bin 1, the inner wall surface of the transverse cavity is sealedly connected to the outer wall surface of the air guide hose 8, a distance adjusting part 9 for adjusting the distance between the two sealing gaskets 6 is provided on the water storage bin 1, and a rotating part 10 for driving the distance adjusting part 9 to rotate is provided on the water storage bin 1;

[0023] Specifically, the distance between the two gaskets 5 can be changed by moving the two moving blocks 4, so as to fix the two ends of the gas flow meter of different sizes, thereby improving the practicability of the device. In addition, when moving the moving blocks 4, the sealing gasket 6 can be aligned with the two ends of the gas flow meter, so that the two sealing gaskets 6 can achieve the effect of sealing the gas flow meter as they gradually approach each other; the distance adjusting part 9 is arranged to drive the two moving blocks 4 to move horizontally, so as to adjust the distance between the two sealing gaskets 6 according to the size of different gas flow meters, thereby eliminating the trouble of manually adjusting the distance between the two moving blocks 4, and at the same time ensuring the stability of the sealing gasket 6 when sealing the gas flow meter.

[0024] like Figure 1 and Figure 3 As shown, the distance adjusting part 9 includes a fixing ring 901, a fixing ring 901 is arranged on the inner wall surface of the water storage tank 1, a plurality of circumferentially distributed meshing cavities 902 are opened on the inner wall surface of the fixing ring 901, a support plate 903 is installed on the inner wall surface of the water storage tank 1, a gear 904 meshing with the meshing cavity 902 is rotatably connected to the other end of the support plate 903, a support plate 2 905 is rotatably connected to the outer wall surface of the gear 904 and the outer wall surface of the moving block 4, and a rotating part 10 for driving the support plate 903 to rotate is arranged on the inner wall surface of the water storage tank 1;

[0025] Specifically, by rotating support plate 903, gear 904 installed on the other end thereof can be driven to rotate along the laying direction of fixed ring 901. At the same time, under the pulling action of support plate 2 905, the movable end of support plate 2 905 can be driven to rotate and connect the movable block 4 to move smoothly in the horizontal direction, thereby achieving the purpose of changing the distance between the two sealing pads 6. The structure is simple and easy to operate.

[0026] like Figure 3As shown, the inner wall surface of the water storage tank 1 and the outer wall surface of the fixing ring 901 are both fixedly mounted with protrusions 906, and a connecting rod 907 is threadedly connected between the two corresponding protrusions 906 at the front and rear;

[0027] Specifically, the threaded connection rod 907 can not only support the fixing ring 901 to ensure the stability and firmness of the fixing ring 901 when in use, but also facilitate the rapid disassembly and replacement of the fixing ring 901 when it fails or wears out, which effectively reduces the replacement cost compared to replacing the entire assembly.

[0028] like Figure 3 and Figure 4 As shown, the rotating part 10 includes a sprocket wheel 102, and the inner wall surface of the water storage tank 1 is rotatably mounted with a sprocket wheel 102 whose other end is fixedly connected to the support plate 903. A sprocket wheel 101 corresponding to the sprocket wheel 102 is mounted on the inner wall surface of the water storage tank 1, and a chain 103 is arranged between the sprocket wheel 101 and the sprocket wheel 102. A motor for driving the sprocket wheel 101 to rotate is arranged inside the water storage tank 1, and the height of the sprocket wheel 101 is located five to ten centimeters above the water surface;

[0029] Specifically, by driving sprocket 101, sprocket 2 102 can be driven to rotate under the action of chain 103, thereby driving support plate 1 903 to rotate, so as to drive moving block 4 to move in the horizontal direction.

[0030] like Figure 1 and Figure 2 As shown, the drainage part 2 includes a water outlet 201. The right inner wall of the water storage tank 1 is provided with the water outlet 201. The water outlet 201 is sealedly connected with a drainage pipe 202. The drainage pipe 202 is provided with a control valve 203.

[0031] Specifically, by opening the control valve 203, all the water inside the water storage tank 1 can be discharged outward through the water outlet 201 and the drain pipe 202, so as to prevent the water from continuously remaining inside the water storage tank 1 and causing damage to various components.

[0032] like Figure 1 As shown, the bottom surface of the inner cavity of the water storage tank 1 is an inclined surface with the left side higher and the right side lower;

[0033] Specifically, by setting the bottom surface of the water storage tank 1 as a slope that is higher on the left and lower on the right, the discharge speed of the water inside the water storage tank 1 is effectively accelerated.

[0034] When in use, the operator places the gas flow meter between the two moving blocks 4 so that the two ends of the gas flow meter are aligned with the sealing gasket 6. Then the driving motor can drive the sprocket 101 to rotate, and with the cooperation of the chain 103, the sprocket 2 102 can be driven to rotate, so that the support plate 1 903 installed on the other end of the sprocket 2 102 can rotate. When the support plate 1 903 rotates, the gear 1 904 can rotate along the laying direction of the multiple meshing cavities 902, ensuring the tightness of the movable end of the support plate 1 903 when it rotates. At the same time, it can also drive the moving block 4 to move smoothly in the horizontal direction under the pull of the support plate 2 905, so that the two sealing gaskets 6 are moved to align with the gas flow meter. The two ends of the meter are tightly fitted. At this time, the sealing gasket 6 has a sealing effect on the two ends of the gas flow meter. Finally, the control valve 203 is closed, and clean water is injected into the water storage tank 1 to make the water level inside the water storage tank 1 lower than the sprocket 101. At the same time, the air pump 7 is driven. Under the conveying action of the air guide hose 8, the gas can be conveyed to the water storage tank 1. When the gas flow meter is inflated by the air pump 7, observe whether there are bubbles in the clean water inside the water storage tank 1. After measuring the sealing line of the gas flow meter, the control valve 203 can be opened to discharge the water inside the water storage tank 1 to avoid damage to various components caused by being soaked in water for a long time. Then, the rotating part 10 can be driven in reverse to take out the gas flow meter.

[0035] In summary: by moving the two moving blocks 4, the distance between the two gaskets 5 can be changed, so as to fix the two ends of the gas flow meter of different sizes, thereby improving the practicability of the device. In addition, when moving the moving blocks 4, the sealing gasket 6 can be aligned with the two ends of the gas flow meter, so that the two sealing gaskets 6 can achieve the effect of sealing the gas flow meter as they gradually approach; the distance adjusting part 9 is arranged, so that the two moving blocks 4 can be driven to move horizontally, so as to adjust the distance between the two sealing gaskets 6 according to the size of different gas flow meters, thereby eliminating the trouble of manually adjusting the distance between the two moving blocks 4, and at the same time can ensure the stability of the sealing gasket 6 when sealing the gas flow meter.
