Description

Technical Field

[0001] This utility model belongs to the field of measuring tube calibration technology, specifically a measuring tube calibration structure for a Coriolis mass flow meter. Background Technology

[0002] A Coriolis mass flow meter is a metering instrument that directly measures the mass flow rate of fluids and offers high stability and reliability. It consists of a sensor and a transmitter. The sensor is the element that resonates and realizes the Coriolis mechanical structure, while the transmitter provides power to the sensor and processes and outputs the signal. The core of the sensor is the measuring tube assembly that provides vibration, which requires good consistency between the two measuring tubes. Since most mass flow meters' measuring tubes are bent one by one using bending equipment such as pipe bending machines or bending fixtures, this results in poor consistency between the two measuring tubes.

[0003] Existing orthopedic structures often require multiple sets of nuts and bolts for installation during assembly and fixation. This method of fixing by rotating multiple sets of nuts is very cumbersome, resulting in a lot of time being wasted on installation and disassembly. It does not allow for convenient installation and disassembly and affects work efficiency. Utility Model Content

[0004] To overcome the above-mentioned defects, this utility model provides a measuring tube correction structure for a Coriolis mass flow meter. It solves the problem that existing correction structures often require multiple sets of nuts and bolts for installation and fixing during assembly. This method of fixing by rotating multiple sets of nuts is very cumbersome, resulting in a lot of time consumption during installation and disassembly, which cannot achieve convenient installation and disassembly and affects work efficiency.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a measuring tube correction structure for a Coriolis mass flow meter, comprising a first module, a second module at the bottom of the first module, placement slots symmetrically provided on opposite sides of the first and second modules, plug blocks fixedly connected to both sides of the first module, a sliding groove on one side of the plug block, a slide rod fixedly connected in the sliding groove, a slide seat slidably connected to the outer arc surface of the slide rod, a first return spring sleeved on the outer arc surface of the slide rod on one side of the slide seat, a snap-fit ​​plate rotatably connected to one side of the slide seat via a pin, a snap-fit ​​groove on one side of the plug block corresponding to the snap-fit ​​plate, an expansion block fixedly connected to the side of the slide seat inside the plug block, the expansion block slidably connected inside the plug block, a reset groove inside the plug block, a reset rod fixedly connected in the reset groove, and snap-fit ​​blocks slidably connected to both ends of the reset rod.

[0006] As a further embodiment of this utility model: a limit block is fixedly connected to one side of the snap-fit ​​block, and a second reset spring is respectively sleeved on both ends of the reset rod located on one side of the snap-fit ​​block.

[0007] As a further embodiment of this utility model: the plug block has limit grooves on both sides of the corresponding reset groove, and the two ends of one side of the snap block are slidably connected through the limit grooves.

[0009] As a further embodiment of this utility model: mounting blocks are symmetrically fixedly connected to the bottom of both sides of the first module, and insert blocks are slidably connected through the mounting blocks.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] 1. The measuring tube correction structure of this Coriolis mass flow meter, by setting up connecting blocks, expansion blocks, and snap-fit ​​blocks, allows the first module and the second module to be installed and fixed when the connecting blocks on both sides of the second module are inserted into the snap-fit ​​blocks. At this time, the sliding seat can be pulled to slide on the sliding rod, which simultaneously drives the expansion block to move. The expansion block is used to squeeze the snap-fit ​​blocks on both sides. At this time, the snap-fit ​​blocks will slide in the limiting groove and on the reset rod. When the limiting block on one side of the snap-fit ​​block is snapped into the snap-fit ​​groove on the inner wall of the connecting block for installation and fixation, the snap-fit ​​plate can be snapped into the snap-fit ​​groove, thereby quickly installing and fixing the first module and the second module.

The measuring tube correction structure of this Coriolis mass flow meter, by setting insert blocks and positioning blocks, when it is necessary to install and fix the first module and the second module, first align the insert blocks on both sides of the first module with the positioning blocks on the surface of the second module, then the first module and the second module can be spliced ​​together. At the same time, insert the insert blocks into the positioning blocks to position the first module and the second module, preventing deviations when installing and fixing the first module and the second module.

[0018] The technical solution of this patent will be further described in detail below with reference to specific embodiments.

[0019] like Figure 1-3 As shown, this utility model provides a technical solution: a measuring tube correction structure for a Coriolis mass flow meter, including a first module 1, a second module 2 at the bottom of the first module 1, and placement grooves 22 symmetrically provided on the opposite side of the first module 1 and the second module 2. The measuring tube is placed into the placement groove 22 through the placement groove 22, and the measuring tube is fixed and corrected through the placement groove 22.

[0020] The first module 1 is fixedly connected to both sides of the plug-in block 3. A sliding groove 4 is opened on one side of the plug-in block 3. A sliding rod 5 is fixedly connected in the sliding groove 4. A sliding seat 6 is slidably connected through the outer arc surface of the sliding rod 5. A first return spring 7 is sleeved on the outer arc surface of the sliding rod 5 located on the side of the sliding seat 6. With the setting of the first return spring 7, when the expansion block 10 finishes to squeeze the locking block 15, the expansion block 10 can be driven to reset by the first return spring 7, so that the expansion block 10 no longer squeezes the locking block 15.

[0021] A snap-fit ​​plate 8 is rotatably connected to one side of the sliding seat 6 via a pin. A snap-fit ​​groove 11 is provided on one side of the plug-in block 3 corresponding to the snap-fit ​​plate 8. An expansion block 10 is fixedly connected to one side of the sliding seat 6 inside the plug-in block 3, and the expansion block 10 is slidably connected inside the plug-in block 3. A reset groove 12 is provided inside the plug-in block 3. A reset rod 13 is fixedly connected inside the reset groove 12. Snap-fit ​​blocks 15 are slidably connected to both ends of the reset rod 13. A limit block 16 is fixedly connected to one side of the snap-fit ​​block 15. A second reset spring 14 is sleeved on one end of the reset rod 13 on one side of the snap-fit ​​block 15. With the setting of the second reset spring 14, when the expansion block 10 no longer squeezes the snap-fit ​​block 15, the elastic force of the second reset spring 14 pushes the two snap-fit ​​blocks 15 to slide and reset on the reset rod 13, so that the limit block 16 on the snap-fit ​​block 15 disengages from the snap-fit ​​groove 18.

[0022] Limiting grooves 9 are respectively opened on both sides of the plug-in block 3 corresponding to the reset groove 12. The two ends of one side of the snap-fit ​​block 15 are respectively slidably connected in the limiting groove 9. By setting the limiting groove 9, when the snap-fit ​​block 15 moves, the two sides of the snap-fit ​​block 15 slide in the limiting groove 9. The limiting groove 9 limits the snap-fit ​​block 15 to prevent deviation when the snap-fit ​​block 15 moves.

[0023] The two sides of the second module 2 are fixedly connected with connecting blocks 17 at the positions corresponding to the plug-in blocks 3. The two inner sides of the connecting blocks 17 are provided with slots 18 at the positions corresponding to the limiting blocks 16. Through the setting of the slots 18 and the limiting blocks 16, the plug-in blocks 15 drive the limiting blocks 16 to be inserted into the slots 18, thereby making the plug-in blocks 3 and the connecting blocks 17 locked together.

[0024] Mounting blocks 19 are symmetrically fixedly connected to the bottom of both sides of the first module 1. Insertion blocks 20 are slidably connected through the mounting blocks 19. Positioning blocks 21 are fixedly connected to the top of both sides of the second module 2 at the positions corresponding to the insertion blocks 20. The bottom surface of the insertion blocks 20 is slidably connected through the positioning blocks 21. By setting the insertion blocks 20 and positioning blocks 21, the insertion blocks 20 are inserted into the positioning blocks 21, thereby positioning the first module 1 and the second module 2, which is convenient for later fixing.

[0025] The working principle of this utility model is as follows: First, the measuring tube is placed into the placement slot 22 at the top of the second module 2. When it is necessary to install and fix the first module 1 and the second module 2, first align the insertion block 20 of the first module 1 with the positioning block 21 of the second module 2, insert the insertion block 20 into the positioning block 21 for positioning. At the same time as positioning, the connecting blocks 17 on both sides of the second module 2 will be inserted into the insertion block 3. At this time, the sliding seat 6 can be pulled. While the sliding seat 6 slides on the slide rod 5, it squeezes the first return spring 7, thus locking the latch on the sliding seat 6. Plate 8 is rotated and snapped into the snap-fit ​​groove 11. When the sliding seat 6 slides, it drives the expansion block 10 to move. When the expansion block 10 moves and contacts the snap-fit ​​block 15, the snap-fit ​​block 15 will be squeezed and slide in the limiting groove 9 and the reset groove 12. At the same time, it slides on the reset rod 13 and pushes the second reset spring 14 to move, moving the limiting block 16 on one side of the snap-fit ​​block 15 into the snap-fit ​​groove 18, thereby snapping and fixing the plug-in block 3 and the connecting block 17, and installing and fixing the plug-in block 20 of the first module 1 and the second module 2.
