Description

Technical Field

[0001] The utility model relates to the field of quick-release connection devices for electromagnetic flowmeters, and more specifically to a quick-release device for electromagnetic flowmeters. Background Art

[0002] Electromagnetic flowmeter is an instrument that uses the principle of electromagnetic induction to measure the flow rate of conductive fluid based on the electromotive force induced when the conductive fluid passes through an external magnetic field.

[0003] Electromagnetic flowmeters need to be calibrated before leaving the factory. This is done by installing the newly produced electromagnetic flowmeter and the standard electromagnetic flowmeter used for calibration on the same pipeline, and letting the medium flow through the standard electromagnetic flowmeter used for calibration and the newly produced electromagnetic flowmeter in sequence. The difference in values ​​displayed on the two electromagnetic flowmeters is calculated to perform calibration.

[0004] Since the electromagnetic flowmeter and the pipeline are both provided with flanges for disassembly and assembly, and the flanges are both provided with multiple bolt holes, when the flange of the electromagnetic flowmeter is installed on the flange of the corresponding pipeline, multiple bolts need to be installed to ensure a stable connection between the electromagnetic flowmeter and one end of the corresponding pipeline. Therefore, when multiple electromagnetic flowmeters need to be calibrated, the multiple electromagnetic flowmeters need to be disassembled and assembled at one end of the corresponding pipeline respectively, which increases the number and frequency of disassembly and assembly of the bolts, and is not conducive to the rapid disassembly and assembly and calibration of the electromagnetic flowmeter. Therefore, we propose a quick-release device for the electromagnetic flowmeter to solve the above-mentioned problems. Utility Model Content

[0028] The top and bottom of the rectangular sleeve 1 located at the connection between the rectangular sleeve 1 and the rectangular sleeve 2 are both provided with tensioning components. The two tensioning components have the same structure and are arranged in reverse symmetry. The tensioning components include a rack 6 fixedly welded to the top of the rectangular sleeve 1 and a group of ears 7 fixedly welded to the top of the rectangular sleeve 2. One end of the rack 6 extends to one side of the rectangular sleeve 2 through the gap between the group of ears 7. The bottom of the rack 6 contacts the top of the rectangular sleeve 2.

A tightening gear 9 is fixedly installed on the rotating shaft 8 between a group of ear pieces 7, and the bottom of the tightening gear 9 is meshed with the top of the rack 6. A limit gear 10 is fixedly installed on one end of the rotating shaft 8 located outside the ear piece 7, and a clamping piece 11 is provided on the top of the limit gear 10. A connecting shaft 12 is rotatably connected to the top of the clamping piece 11. One end of the connecting shaft 12 is fixedly welded to one side of the ear piece 7, and the bottom of the clamping piece 11 is clamped with the top of the limit gear 10. A sleeve 13 is fixedly welded to the other end of the rotating shaft 8 located outside the ear piece 7, and a plurality of force rod sockets 1301 are opened on the outer wall of the sleeve 13.

[0029] The use principle of the quick release device of this electromagnetic flowmeter is:

[0030] When the electromagnetic flowmeter 3 needs to be installed at one end of the pipeline 4, the flange part 301 on the electromagnetic flowmeter 3 is first connected with the flange part 301 on the pipeline 4 by using the sealing gasket 5, and the sealing edge 501 is inserted into the inner wall of the channel of the corresponding flange part 301 to improve the sealing of the connection. Then, the rectangular frame 1 is put on the outer side of the flange part 301 of the electromagnetic flowmeter 3, and the rectangular frame 2 is put on the outer side of the flange part 301 of the pipeline 4, and the racks 6 at the top and bottom of the rectangular frame 1 are respectively inserted into a group of ear pieces 7 at the top and bottom of the rectangular frame 2, so that the racks 6 are in a group of ear pieces 7 and mesh with the teeth of the corresponding tightening gear 9, and then a crowbar is used to insert the top and bottom of the racks 6 into the corresponding gears 9. The inside of the force rod socket 1301 of the part is pressed continuously to drive the corresponding sleeve 13 to rotate. At this time, the rotating shaft 8 rotates and drives the corresponding tightening gear 9 to rotate, forcing the rack 6 to move to one side of the pipe 4, so as to achieve the effect of moving the rectangular sleeve 1 to the side of the rectangular sleeve 2, and tightening the connection between the two flange parts 301, until the tightening degree satisfies the tight connection between the two flange parts 301. In this process, the rotation of the rotating shaft 8 will also drive the rotation of the limit gear 10. Therefore, in this process, it is also necessary to peel off the clamping member 11 from the state of being engaged with the limit gear 10, and the clamping member 11 can be released only after the tightening is completed, so that the clamping member 11 clamps the limit gear 10, so as to achieve the effect of limiting the tightening gear 9;

[0031] When the electromagnetic flowmeter 3 needs to be removed from one end of the pipeline 4, it is only necessary to peel off the clamp 11 from the state of being engaged with the limit gear 10. At this time, the limit gear 10 and the tightening gear 9 can be supported to rotate in the opposite direction under the elastic action of the sealing gasket 5, thereby releasing the tight connection between the two flange parts 301. Then, the rectangular frame 1 together with the electromagnetic flowmeter 3 is removed from one end of the pipeline 4, and the connection with the rack 6 is pulled out. Then, the rectangular frame 1 is removed from the flange part 301 of the electromagnetic flowmeter 3. At this time, the next new electromagnetic flowmeter 3 can be installed.

[0032] Embodiment 2:

[0036] The positioning rod 14 and the sliding hole 15 can assist the directional movement of the rectangular sleeve 1, and provide a limiting structure for the stability of the rectangular sleeve 1 when it moves toward the side of the rectangular sleeve 2 during tightening.

[0037] The rectangular sleeve 1 and the rectangular sleeve 2 are both provided with a U-shaped frame 101 and a connecting rod 102. Both ends of the U-shaped frame 101 are fixedly connected with docking ends 1011. Two docking grooves 1021 are provided inside the connecting rod 102 at the positions of the two docking ends 1011. The U-shaped frame 101 and the connecting rod 102 are detachably connected through the corresponding docking ends 1011 and the docking grooves 1021. Threaded holes are provided on the docking grooves 1021 and the docking ends 1011. The docking grooves 1021 and the docking ends 1011 are detachably connected through screws.

[0038] By setting the rectangular frame 1 and the rectangular frame 2 to be a detachable structure with a U-shaped frame body 101 and a connecting rod portion 102, it is convenient for the rectangular frame 1 and the rectangular frame 2 to be respectively sleeved on the outer sides of the flange portion 301 of the electromagnetic flowmeter 3 and the pipeline 4, thereby facilitating the disassembly and assembly of the rectangular frame 1 and the rectangular frame 2 and reducing the probability of frequent disassembly and assembly of the screws.

[0039] A torsion spring is sleeved on the outer side of the connecting shaft 12, one end of the torsion spring is clamped with one side of the corresponding ear piece 7, and the other end of the torsion spring is clamped with one side of the clamping member 11;
