Description

Technical Field

[0001] This utility model relates to the field of flow meter calibration technology, and in particular to a flow meter calibration device. Background Technology

[0002] Chinese patent document CN221706696U discloses a flow meter calibration device, relating to the field of flow meter technology. This invention includes a water tank, with side plates fixedly connected to the left and right sides of the top of the tank. Water supply pipes are provided at both ends of the water tank, with the output ends of the water supply pipes passing through the side plates and fixedly connected to the outlet pipes. Lifting components with a lifting function are provided on the left and right sides of the top of the water tank, and a clamping component with a clamping function is provided at the top of the lifting components. When the external controller is activated, a stepper motor starts and drives a rotating shaft to rotate forward through its output end. The rotating shaft drives two second bevel gears to rotate forward, and the second bevel gears drive a first bevel gear meshing with them to rotate forward. The first bevel gear, in turn, drives a second linkage rod to rotate forward through a rotating rod. The second linkage rod then pulls the clamping rod closer together inside the sliding groove, clamping the flow meter and achieving a fixed position for the flow meter, preventing it from easily moving.

[0003] When using the above-mentioned flow meter calibration device, only the flow meter body can be fixed. Multiple sets of bolts are also required to connect the water pipe to the flange rings on both sides of the flow meter for installation. This makes the operation more troublesome, time-consuming and labor-intensive for the staff, and reduces the calibration efficiency of the device. Utility Model Content

The output shaft of the brake motor is fixedly connected to one end of the rotating rod, and the outer wall of the rotating rod is fixedly connected to the inside of the gear. The gear meshes with two sets of toothed plates. The operator only needs to place the flow meter between the mounting plates and clamp the annular block on both sides of the flow meter to install and fix the flow meter, which reduces the workload of the operator in the disassembly and assembly process, saves time and effort, and improves the usability and practicality of the device.

[0007] Preferably, multiple sets of annularly distributed positioning rods are fixedly installed on the adjacent sides of the annular block, so that the positioning rods can be inserted into the holes of the flowmeter flange ring, which can quickly position the flowmeter without the need for manual alignment, and can also play a supporting role, thus improving the calibration efficiency of the device.

[0008] Preferably, sealing gaskets are provided on adjacent sides of the annular block.

The disassembly and assembly mechanism 2 is disposed on the top of the calibration water tank 1. The disassembly and assembly mechanism 2 includes a hollow block 201, a sliding block 205, a toothed plate 206, a mounting plate 207, and an annular block 208.

[0021] Secondly, the disassembly and assembly mechanism 2 also includes a brake motor 202, a rotating rod 203, and a gear 204. The brake motor 202 is fixedly installed on the top of the calibration water tank 1.

Then, the annular blocks 208 are clamped on both sides of the flow meter, and the sealing gasket 4 is attached to the flow meter to prevent water leakage.
