[0014] (III) Beneficial effects

[0015] Compared with the prior art, the present invention provides a combined flow meter with the following beneficial effects:

[0016] 1. The combined flow meter uses fixings to connect the two connecting ring plates a with the two connecting ring plates b respectively, and then uses two flanges to connect the device to the pipeline. Then, the two screws are rotated upward to drive the two lifting rods to move upward respectively, thereby driving the two lifting columns to move upward respectively, so that the fluid can pass through the main body, thereby detecting the flow. When the main body is damaged and needs to be repaired, the two screws are rotated downward to drive the two lifting columns to move downward respectively, so that the two short tubes b can be blocked by the lifting columns, so that the fluid will flow upward through the L-shaped groove, and then through the connecting pipe. The fluid continues to flow, so that the user can make the fluid continue to flow after disassembling the main body to avoid affecting the use.

[0017] 2. The combined flow meter can limit the four limit blocks to move only up and down through the four vertical grooves, so that the two lifting circular plates can only move up and down, so that the lifting rod can only move up and down, so that the lifting column can remain stable and will not rotate when it moves up and down, so as to avoid the situation where the two short tubes a cannot be connected with the two L-shaped grooves, resulting in the inability of the fluid to flow.

[0018] 3. The combined flow meter can prevent the fluid from flowing through the gap between the vertical pipe and the lifting circular plate through two sealing circular plates, and at the same time, the limit block and the vertical groove can be sealed through the sealing block, so as to prevent fluid leakage from affecting the use.

[0019] 4. The combined flow meter can perform sealing when the two connecting ring plates a are respectively connected to the two connecting ring plates b through the sealing ring. At the same time, the movable bar can be driven to rotate through the rotating ring, thereby driving the screw to rotate, so that the user can rotate the screw conveniently, thereby avoiding direct contact with the screw to cause finger cuts.

[0020] 5. The combined flow meter places the two connecting ring plates a on the main body in the connecting grooves on the two half-ring blocks a respectively, and then rotates the moving screw upward, so that the two connecting plates can be driven to move upward respectively through the four limit rings, and the two half-ring blocks b can be driven to move upward respectively through the four vertical bars. In this way, the two half-ring blocks a and the two half-ring blocks b can be used to fix the main body while the fluid enters the main body. When the main body needs to be disassembled, the two half-ring blocks b can be put down while blocking the main body, so that the user can take out the main body conveniently.

[0021] 6. The combined flow meter can limit the four vertical bars through two vertical blocks to prevent the vertical bars from rotating when moving up and down. At the same time, the round rod is passed through the two rotating rings and the hook is hung on the rotating ring. In this way, the round tube can be used to prevent the rotating ring from accidentally rotating too much, which will reduce the fixing effect of the device and affect its use. At the same time, the air pipe and the air groove can make the air above the lifting circular plate connected to the outside world to avoid the internal air pressure affecting its use.

After the two connecting ring plates a31 are respectively connected with the two connecting ring plates b25 by using fixings, the device is connected to the pipeline by using two flanges 6, and then the two screws 17 are rotated upward to respectively drive the two lifting rods 24 to move upward, thereby respectively driving the two lifting columns 26 to move upward, so that the fluid can pass through the main body 1, so that the flow rate can be detected. When the main body 1 is damaged When maintenance is needed, the two screw rods 17 can be rotated downward to respectively drive the two lifting columns 26 to move downward, so that the lifting columns 26 can be used to block the two short tubes b36, so that the fluid will flow upward through the L-shaped groove 28, and then through the connecting pipe 8. The fluid continues to flow, so that the user can allow the fluid to continue to flow after disassembling the main body 1 to avoid affecting the use. The two lifting rods 24 are fixedly sleeved with a lifting circular plate 20, and the two lifting circular plates 20 are fixedly installed with two limit blocks 23. The inner side walls of the two vertical pipes 5 are provided with two vertical grooves 19, and the four limit blocks 23 are respectively movably connected to the two vertical grooves 19. The four limit blocks 23 can be limited to move up and down through the four vertical grooves 19, so that the two lifting The lowering circular plate 20 can only move up and down, so that the lifting rod 24 can only move up and down, so that the lifting column 26 can remain stable and will not rotate when it moves up and down, so as to avoid the situation that the two short tubes a7 cannot be connected with the two L-shaped grooves 28, resulting in the inability of the fluid to flow.

An annular wall groove 30 is provided on the side of the two connecting ring plates a31 away from each other. A sealing ring 29 is fixedly installed in each of the two annular wall grooves 30. Two rotating rings 11 are provided on the two screw rods 17. A plurality of movable bars 37 are fixedly installed on the inner walls of the two rotating rings 11. Each movable bar 37 is fixedly connected to the two screw rods 17 respectively. The sealing ring 29 can be used to perform sealing when the two connecting ring plates a31 are respectively connected to the two connecting ring plates b25. At the same time, the rotating ring 11 can drive the movable bar 37 to rotate, thereby driving the screw rod 17 to rotate. This makes it convenient for users to rotate the screw rod 17. To avoid direct contact with the screw 17 and causing finger cuts, the two connecting ring plates b25 are fixedly installed with half-ring blocks a2, the two screws 17 are movably sleeved with connecting plates 16, the upper and lower sides of the two connecting plates 16 are fitted with limit rings 10, and the four limit rings 10 are respectively fixedly sleeved on the two screws 17, and two vertical bars 12 are fixedly installed on the lower sides of the two connecting plates 16. A half-ring block b3 is arranged under the two half-ring blocks a2, and the two half-ring blocks b3 are respectively fixedly connected to the four vertical bars 12. The inner side walls of the two half-ring blocks a2 and the two half-ring blocks b3 are provided with connecting grooves 18. By placing the two connecting ring plates a31 on the main body 1 on the two half-ring blocks a2, The screw 17 is then rotated upward to move the screw 17, so that the two connecting plates 16 can be driven to move upward through the four limit rings 10, so that the two semi-ring blocks b3 can be driven to move upward through the four vertical bars 12, so that the two semi-ring blocks a2 and the two semi-ring blocks b3 can be used to fix the main body 1 while the fluid enters the main body 1. When the main body 1 needs to be disassembled, the two semi-ring blocks b3 can be put down while blocking the main body 1, so that it is convenient for the user to take out the main body 1. Two vertical blocks 13 are fixedly installed on the two vertical pipes 5, and circular grooves 14 are opened on the four vertical blocks 13. Round rods 38 are movably connected in the four circular grooves 14. The four round rods The upper end of each of the two top plates 9 is fixedly provided with a hook 15, and each of the two top plates 9 is fixedly provided with an air pipe 33, and each of the two air pipes 33 is fixedly provided with a small plate 35, and each of the two air pipes 33 has an air groove 34 on its side wall. The four vertical bars 12 can be restricted by the two vertical blocks 13 to prevent the vertical bars 12 from rotating when they move up and down. At the same time, the round rod 38 is passed through the two rotating rings 11, and the hook 15 is hung on the rotating ring 11. In this way, the round rod 38 can be used to prevent the rotating ring 11 from rotating too much by accident, which may cause the fixing effect of the device to decrease and affect its use. At the same time, the air pipe 33 and the air groove 34 can make the air above the lifting circular plate 20 communicate with the outside world to prevent the internal air pressure from affecting its use.

[0035] When in use, the first step is: after using the fixing parts to connect the two connecting ring plates a31 with the two connecting ring plates b25 respectively, use the two flanges 6 to connect the device to the pipeline, and then rotate and move the two screws 17 upward to respectively drive the two lifting rods 24 to move upward, thereby respectively driving the two lifting columns 26 to move upward, so that the fluid can pass through the main body 1, thereby detecting the flow rate. When the main body 1 is damaged and needs to be repaired, the two screws 17 are rotated downward to respectively drive the two lifting columns 26 to move downward, so that the two short tubes b36 can be blocked by the lifting columns 26, so that the fluid will flow upward through the L-shaped groove 28, and then through the connecting pipe 8. The fluid continues to flow, so that the user can allow the fluid to continue to flow after disassembling the main body 1 to avoid affecting the use.

[0036] Step 2: The four limit blocks 23 can be restricted to move up and down by the four vertical grooves 19, so that the two lifting circular plates 20 can only move up and down, so that the lifting rod 24 can only move up and down, so that the lifting column 26 can remain stable and will not rotate when it moves up and down, so as to avoid the situation that the two short tubes a7 cannot be connected with the two L-shaped grooves 28, resulting in the inability of the fluid to flow.

[0037] Step 3: The two sealing circular plates 21 can prevent the fluid from flowing through the gap between the vertical pipe 5 and the lifting circular plate 20. At the same time, the sealing block 22 can be used to seal the limit block 23 and the vertical groove 19, thereby preventing fluid leakage from affecting use.

[0038] Step 4: The sealing ring 29 can be used to perform sealing when the two connecting ring plates a31 are respectively connected to the two connecting ring plates b25. At the same time, the rotating ring 11 can drive the movable bar 37 to rotate, thereby driving the screw 17 to rotate. This makes it convenient for users to rotate the screw 17, thereby avoiding direct contact with the screw 17 and causing finger cuts.

[0039] Step 5: By placing the two connecting ring plates a31 on the main body 1 in the connecting grooves 18 on the two half-ring blocks a2 respectively, and then rotating the screw 17 upward, the two connecting plates 16 can be driven to move upward through the four limit rings 10 respectively, so that the two half-ring blocks b3 can be driven to move upward through the four vertical bars 12 respectively, so that the two half-ring blocks a2 and the two half-ring blocks b3 can be used to fix the main body 1 while allowing the fluid to enter the main body 1. When the main body 1 needs to be disassembled, the two half-ring blocks b3 can be put down while blocking the main body 1, so that the user can take out the main body 1 conveniently.

[0040] Step 6: The four vertical bars 12 can be restricted by the two vertical blocks 13 to prevent the vertical bars 12 from rotating when moving up and down. At the same time, the round rod 38 is passed through the two rotating rings 11 and the hook 15 is hung on the rotating ring 11. In this way, the round rod 38 can be used to prevent the rotating ring 11 from accidentally rotating too much, which will cause the fixing effect of the device to decrease and affect its use. At the same time, the air pipe 33 and the air groove 34 can make the air above the lifting circular plate 20 connected to the outside world to avoid the internal air pressure affecting its use.
