Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of electromagnetic flowmeter, more specifically, the utility model relates to a kind of electromagnetic flowmeter of easy installation. BACKGROUND

[0002] Electromagnetic flowmeter is a new type of flow measuring instrument that has developed rapidly with the development of electronic technology. It is an instrument that measures the flow of conductive fluid based on the induced electromotive force generated when the conductive fluid passes through an external magnetic field using electromagnetic induction principle. Due to the different specifications of electromagnetic flowmeters, there is a significant difference in their own weight. External auxiliary equipment is needed to assist in installation during installation. For example, the patent with the publication number CN220912373U discloses a kind of electromagnetic flowmeter of easy installation. By rotating the hand wheel to drive the screw sleeve to rotate, the screw sleeve moves vertically along the outer wall of the screw rod, which drives the support plate to move. It is convenient to adjust the installation height of the flowmeter body according to the difference between the connecting pipe and the ground. By pressing the protrusion, the two sliders are separated, and then the connecting block on the flowmeter body is inserted into the slot. When the protrusion is released, the spring extends under its own elastic force, which drives the protrusion to move. The protrusion drives the connecting rod to move, and the connecting rod drives the connecting strip to move. The connecting strip drives the hinged rod to move and rotate around the hinge point.

[0003] The above device allows two sliders to drive two clamps to move and be clamped in the clamping groove, thereby fixing the connecting block and supporting the flowmeter body, which facilitates the quick installation of the flowmeter body and avoids simultaneous assembly by multiple people, saving time and effort and improving installation efficiency. However, when using it, the electromagnetic flowmeter needs to be installed on the upper end of the support plate, which is inconvenient to adjust when the pipeline is not aligned, making the installation of the electromagnetic flowmeter inconvenient.

The drawings are merely illustrative of this disclosure and are not necessarily drawn to scale. The same reference numerals in the drawings denote the same or similar parts, and therefore repeated descriptions of them will be omitted.

[0029] This utility model provides an easy-to-install electromagnetic flowmeter, such as... Figure 1 and 2As shown, it includes an electromagnetic flowmeter body 1, with connecting pipes 2 at both ends. A concave limiting groove 8 is provided on one side of the outer end face of the electromagnetic flowmeter body 1, and an annular mounting part 7 is provided on the outside of the end face of the concave limiting groove 8.

[0030] One end of the connecting pipe 2 is provided with a connecting flange 6, the upper end of the electromagnetic flowmeter body 1 is provided with a connecting rod 4, the upper end of the connecting rod 4 is provided with a converter 5, both ends of the electromagnetic flowmeter body 1 are provided with mounting flanges 9, and the end faces of the connecting flange 6 and the mounting flange 9 are provided with mounting holes 3, which can be used to pass bolts through the mounting holes 3 on the end faces of the connecting flange 6 and the mounting flange 9, and to connect and fix the connecting flange 6 and the mounting flange 9 by bolts;

[0031] The inner end face of the electromagnetic flowmeter body 1 is provided with an inner liner 10, which can effectively prevent the transported liquid from corroding the interior of the electromagnetic flowmeter body 1, thereby increasing the service life of the electromagnetic flowmeter body 1. One end of the inner liner 10 is provided with a sealing mounting sleeve 11, which can effectively increase the sealing of the connection between the electromagnetic flowmeter body 1 and the connecting pipe 2. The number of concave limiting grooves 8 and annular mounting parts 7 are both provided in two, and they are set in a mirror state on both sides of the vertical central axis in the main viewing direction of the electromagnetic flowmeter body 1.

[0032] The outer end face of the connecting flange 6 in the right-view direction is coplanar with the outer end face of the mounting flange 9 in the right-view direction. The converter 5 is electrically connected to the external control device. There are multiple mounting holes 3, which are arranged in a ring array outside the center point of the mounting flange 9 in the right-view direction. The inner liner 10 and the sealing mounting sleeve 11 are made of rubber.

[0033] like Figure 3 , 4 As shown in Figure 5, the inner end face of the annular mounting component 7 is provided with a limiting groove 12. The limiting groove 12 is provided with a roller 16, which can be easily installed inside the limiting groove 12. At the same time, when the annular mounting component 7 is installed, the outer end face of the roller 16 will fit against the inner end face of the concave limiting groove 8, thereby facilitating the adjustment of the annular mounting component 7 at different angles. The upper side of the outer end face of the annular mounting component 7 is provided with a support rod 14. The outer end face of the annular mounting component 7 is provided with a limiting rod 13 on the side near the support rod 14. When installing the electromagnetic flowmeter body 1, the support rod 14 and the limiting rod 13 can be overlapped on the upper end of the mounting flange 9 at one end of the connecting pipe 2.

[0034] One end of the support rod 14 is provided with a limiting block 15. The limiting block 15 makes the support rod 14 lock onto the upper end of the mounting flange 9 at one end of the connecting pipe 2, and makes the electromagnetic flowmeter body 1 stably locked onto one side of the mounting flange 9. There are multiple limiting grooves 12, which are arranged in a ring array outside the center point of the annular mounting part 7 in the right view direction. There are multiple rollers 16, which are arranged in a ring array outside the center point of the electromagnetic flowmeter body 1 in the right view direction.

[0035] The inner end face of the limiting groove 12 in the right-view direction is adapted to the outer end face of the roller 16 in the right-view direction. The outer end face of the roller 16 in the right-view direction is in contact with the inner end face of the concave limiting groove 8. There are two limiting rods 13, which are set on both sides of the vertical central axis in the right-view direction of the annular mounting part 7. When installing the electromagnetic flowmeter body 1, the electromagnetic flowmeter body 1 can be lifted, and then the supporting top rods 14 and limiting rods 13 on both sides can be connected to the upper end of the mounting flange 9 at one end of the connecting pipe 2. The supporting top rods 14 are locked in the upper end of the mounting flange 9 by the limiting block 15. Then the electromagnetic flowmeter body 1 is supported by the annular mounting part 7.

[0036] When the operator rotates the electromagnetic flowmeter body 1, the rollers 16 will press against the concave limiting groove 8, thereby supporting the rotation of the electromagnetic flowmeter body 1. When the electromagnetic flowmeter body 1 rotates, the mounting holes 3 opened on the end face of the connecting pipe 2 and the mounting flange 9 are aligned. Then, the connecting bolts can be installed by passing through the inside of the mounting holes 3, and the connecting flange 6 and the mounting flange 9 are locked and fixed to avoid the heavy electromagnetic flowmeter body 1 causing inconvenience to the installation of the electromagnetic flowmeter body 1.

[0037] When a conductive fluid flows in a magnetic field, it cuts magnetic lines of force, thereby generating an induced electromotive force on the electrodes on both sides of the pipe. The magnitude of this induced electromotive force is proportional to the magnetic induction intensity, the inner diameter of the pipe, and the average flow velocity of the liquid. The induced electromotive force is measured and transmitted to a converter, where it is amplified and processed to be converted into a standard flow signal.
