Description

Technical Field

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

[0002] A liquid flow meter calibration device is used to verify and calibrate the performance of liquid flow meters. It tests the accuracy and stability of the flow meter by simulating fluid flow under different flow conditions. The main purpose of the calibration device is to ensure the accuracy and reliability of the flow meter in practical applications, especially in industrial production and experimental research, where the accuracy of the flow meter is crucial for flow control and measurement.

[0003] Since most liquid flow meter calibration devices in related technologies use a horizontal pipeline layout, this design cannot meet the calibration requirements of vertical pipelines for float flow meters. To complete the calibration of float flow meters, it is usually necessary to cut, modify, or construct the existing pipeline, which not only increases the complexity of operation but may also cause irreversible structural damage to the original equipment, limiting the versatility and flexibility of the device.

[0004] In view of this, the present invention aims to at least partially solve one of the related technical problems.

[0005] To achieve the above objectives, the technical solution of this utility model is implemented as follows:

[0007] The fixed frame is vertically arranged, and the first fixed structure and the second fixed structure are symmetrically arranged on the fixed frame. The first fixed structure and the second fixed structure are used to install the float flow meter.

[0008] The rear straight pipe and the front straight pipe are symmetrically arranged on the upper and lower sides of the fixed frame. Both the rear straight pipe and the front straight pipe are used to connect to the float flow meter.

[0011] The movable structure is disposed on the lower end face of the fixed frame.

[0012] Furthermore, the first fixing structure includes two support frames and two movable hanging plates. The two support frames are symmetrically arranged on the upper part of the fixing frame, and the two movable hanging plates are symmetrically arranged on the lower end face of the two support frames.

The first fixing structure is the same as the second fixing structure.

[0013] Furthermore, the clamping mechanism includes a clamping cylinder, a cylinder mounting plate, a guide plate, and multiple guide structures. The clamping cylinder is mounted on the top end face of the fixed frame via the cylinder mounting plate. The output end of the clamping cylinder is connected to the top of the first connecting sleeve. The outer wall of the first connecting sleeve slides in cooperation with the multiple guide structures via the guide plate. The multiple guide structures are symmetrically arranged on the two support frames. The end of the first connecting sleeve that cooperates with the rear straight pipe is provided with a sealing structure.

The symmetrical fixing frame guarantees vertical installation of the float flowmeter, conforming to its design and operating principles. Traditional devices often require pipeline cutting, modification, or re-construction when using float flowmeters, increasing operational complexity and potentially causing irreversible structural damage to existing equipment.

The fixed frame 500 is vertically arranged, and the first and second fixing structures are symmetrically arranged on the fixed frame 500. The first and second fixing structures are used to install the float flowmeter 300. The rear straight pipe 200 and the front straight pipe 400 are symmetrically arranged on the upper and lower sides of the fixed frame 500. Both the rear straight pipe 200 and the front straight pipe 400 are used to connect the float flowmeter 300.

[0034] The vertically mounted fixed frame 500, combined with the symmetrical upper and lower fixing structure of the float flowmeter 300, ensures correct installation of the flowmeter in vertical pipelines. The symmetrical fixing frame guarantees vertical installation of the float flowmeter 300, conforming to its design and operating principles. Traditional installations using the float flowmeter 300 often require pipeline cutting, modification, or reconstruction, increasing operational complexity and potentially causing irreversible structural damage to existing equipment. This new design avoids these problems. Its modular and flexible installation method directly adapts to the installation requirements of the float flowmeter 300 without requiring modifications to existing equipment, thus improving the device's versatility and flexibility.

[0035] The output end of the clamping mechanism is connected to the first connecting sleeve 110; the movable structure is disposed on the lower end face of the fixed frame 500.

The first fixing structure is the same as the second fixing structure. Both the first and second fixing structures are used to install the float flowmeter 300, and the symmetrical structure ensures the stable installation of the float flowmeter 300.

Driven by the cylinder, the clamping mechanism can precisely adjust the connection state between the float flowmeter 300 and the pipeline, avoiding leakage or inaccurate connection, and improving the stability and accuracy during the calibration process.
