Description

Technical Field

[0001] The utility model relates to the technical field of flowmeter processing, in particular to an electromagnetic flowmeter encapsulation device. Background Technique

[0002] During the production of an electromagnetic flowmeter, a lining needs to be encapsulated inside the wall of the flow tube of the electromagnetic flowmeter to reduce the wear state of the flow tube.

[0003] The encapsulation uses a hydraulic pressing method to press the lining into the flow tube. During this process, a fixture is required for positioning. Currently, during the use of the fixture, the specimen is usually fixed by a symmetric clamping method, which sometimes causes a deviation in the coaxiality between the flow tube and the lining tube, and the lining tube is easily damaged during pressing, increasing the consumption of the lining.

[0004] Therefore, we propose an electromagnetic flowmeter encapsulation device to solve the existing problems. Content of the Utility Model

[0005] The purpose of the utility model is to propose an electromagnetic flowmeter encapsulation device for the problems existing in the background technique.

[0006] To achieve the above purpose, the utility model provides the following technical solution: an electromagnetic flowmeter encapsulation device, including a bottom table, a flow tube, a lining tube and a back plate. Three locking components are arranged on the upper surface of the bottom table in a circular array distribution. The flow tube is located between the three locking components. The back plate is arranged on the upper surface of the bottom table. A pressing plate is arranged on the back plate through a hydraulic component for lifting and lowering. A positioning sleeve is arranged on the back plate through a sliding component for lifting and lowering. The axis surrounded by the positioning sleeve and the three locking components is in a coaxial state. The lining tube is inserted on the positioning sleeve.

[0007] Preferably, the locking component is composed of a chute, a screw, a pressing block and a pressure sensor. The chutes are arranged on the bottom table in a circular array. The screw is rotatably arranged in the chute.

[0008] Preferably, the pressing block is slidably installed in the chute and is in a threaded engagement state with the screw. The pressure sensor is embedded at the end of the pressing block. The pressure sensor contacts the outer wall of the flow tube.

[0009] Preferably, a threaded hole adapted to the screw is formed on the pressing block. The screw is threadedly installed on the threaded hole.

[0010] Preferably, the hydraulic component is composed of a hydraulic cylinder. The hydraulic cylinder is arranged on the upper surface of the back plate. The pressing plate is fixed on the output end of the hydraulic cylinder.

[0011] Preferably, the sliding component is composed of a connecting rod and a sliding rod. The sliding rod is fixed on the back plate, one end of the connecting rod is slidably connected to the sliding rod, and the other end of the connecting rod is fixed on the positioning sleeve.

[0012] Preferably, a perforation adapted to the sliding rod is formed on the connecting rod, and the sliding rod is movably inserted into the perforation.

[0013] Preferably, a support seat is provided on the lower surface of the base table. There are four support seats in total, and the positions of the four support seats are distributed in a rectangular array on the lower surface of the base table.

[0014] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0015] During the use of the electromagnetic flowmeter encapsulation device of the present utility model, the flow tube of the electromagnetic flowmeter that needs to be encapsulated on the inner wall can be placed between the three locking components, and an external power supply is connected. At the same time, the pressure sensor is connected to an external computer to display data. The three pressing blocks move synchronously so that the pressure sensor abuts against the outer wall of the flow tube. When the pressure sensor reaches the specified pressure value, the locking components are controlled to stop working, and the position of the flow tube can be positioned by the three pressing blocks. At this time, the flow tube and the positioning sleeve are in a coaxial state;

[0016] Then, the lining tube is inserted into the positioning sleeve, and the positioning sleeve positions the lining tube to ensure that the flow tube and the lining tube are coaxial. Then, the hydraulic component controls the pressing plate to move down to press the lining tube into the flow tube of the electromagnetic flowmeter;

[0017] In the present utility model, the flow tube is positioned by the three locking components, and the lining tube is positioned by the positioning sleeve, avoiding deviation in the coaxiality between the flow tube and the lining tube and reducing unnecessary loss of the lining tube.

[0027] Based on Embodiment 1:

[0028] During the use of the electromagnetic flowmeter encapsulation device of the present invention, the flow tube 4 of the electromagnetic flowmeter that needs to be encapsulated on the inner wall can be placed between the three locking components, connected to an external power supply, and at the same time, the pressure sensor 13 is connected to an external computer to display data. The three pressing blocks 12 move synchronously so that the pressure sensor 13 abuts against the outer wall of the flow tube 4. When the pressure sensor 13 reaches the specified pressure value, the locking components are controlled to stop working, and the position of the flow tube 4 can be positioned by the three pressing blocks 12. At this time, the flow tube 4 and the positioning sleeve 5 are in a coaxial state;

[0029] Then, the liner tube 6 is inserted into the positioning sleeve 5. The positioning sleeve 5 positions the liner tube 6 to ensure that the flow tube 4 and the liner tube 6 are coaxial. Then, the hydraulic component controls the pressing plate 14 to move downward to press the liner tube 6 into the flow tube 4 of the electromagnetic flowmeter.
