Description
Technical Field
[0001] The utility model relates to the technical field of electromagnetic flowmeters, in particular to an electromagnetic flowmeter with a flushing function. Background Art
[0002] Electromagnetic flowmeter is a new type of flow measurement instrument that developed rapidly in the 1950s and 1960s with the development of electronic technology. 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. In simple terms, electromagnetic flowmeter is composed of a flow sensor transmitter.
[0003] The electromagnetic flowmeters currently on the market are often used in the chemical wastewater transportation industry. After the electromagnetic flowmeter is used for a long time, a large amount of chemical dirt may be stored inside the pipe. If it is not cleaned for a long time, it will affect the service life of the electromagnetic flowmeter. If it is flushed directly, the dirt on the inner wall of the pipe may be too stubborn. Ordinary water flow cannot remove the stubborn dirt. Therefore, cleaning agents need to be added to the pipe. If the entire pipe is disassembled during the addition of the cleaning agent, it will be time-consuming and laborious.
[0004] To this end, we propose an electromagnetic flowmeter with flushing function. Summary of the invention

[0011] Preferably, a guide rail is fixedly mounted on the upper surface of the mounting plate, a guide block is fixedly connected to the back side of the mounting block, and the guide rail is slidably connected to the guide block.
[0012] Preferably, the limit assembly comprises a vertical plate, which is fixedly connected to the front right side of the upper surface of the mounting plate, a limit rod is inserted into the right side of the vertical plate, a round block is fixedly connected to the right side of the limit rod, and a second spring is fixedly connected between the round block and the vertical plate.
[0013] Preferably, the size of the limiting rod matches the size of the arc-shaped groove.
[0014] The utility model has at least the following beneficial effects:
[0015] 1. When it is necessary to clean the inner wall of the electromagnetic meter body, the staff will first move the pull rod downward by hand. At this time, the pull rod drives the rotating rod to rotate. After the rotating rod rotates, the disc fixedly connected to the rotating rod and the arc groove fixedly installed on the surface of the disc will rotate synchronously in the positive direction. At this time, the round rod will be guided by the arc groove, so that the mounting block connected to the round rod can be lowered. The guide block slides in the guide rail, and the guide block drives the mounting block to slide, which can provide a guide for the descent of the mounting block. At the same time, the round tube connected to the mounting block will be synchronously lowered. At this time, the bottom of the round tube The end will move to the interior of the electromagnetic meter body, and then the spray device body is inserted into the interior of the round tube. At this time, a water pump is connected to the upper end of the round tube, and then the cleaning agent is controlled to be sprayed from the bottom end of the spray device body through the spray port into the interior of the electromagnetic meter body. At this time, the staff can turn the handle by hand, and the bottom end of the round tube can be controlled to rotate to avoid uneven spraying. Then the entire device is left to stand for a period of time. At this time, the working pipe can be directly opened to make the electromagnetic meter body work. At this time, the water flow will directly rinse the inner wall of the electromagnetic meter body clean.
[0016] By setting up a chemical dosing and flushing component, it is possible to add chemicals to the inside of the electromagnetic flow meter body and then flush it clean, solving the current problem that after the electromagnetic flow meter is used for a long time, a large amount of chemical dirt may be stored inside its pipeline. If it is flushed directly, the dirt on the inner wall of the pipeline may be too stubborn and ordinary water flow cannot remove the stubborn dirt.
[0017] 2. When the arc groove is rotated in the positive direction, the bottom surface of the arc groove will contact the inclined surface of the limit rod, which will squeeze the limit rod. At this time, the limit rod will move to the right, so that the position of the limit rod is parallel to the arc groove. Under the influence of the elastic force of the second spring, the limit rod will be stuck in the inside of the arc groove, thereby limiting the position of the arc groove. There is no need for the staff to keep pressing the pull rod.
[0018] The position of the arc groove can be limited by the limit assembly, which can further save workers effort when performing the dosing and flushing work. BRIEF DESCRIPTION OF THE DRAWINGS

A round tube 12 is inserted into the upper surface of the mounting plate 3, and a spraying port 13 is opened at the lower part of the outer surface of the round tube 12. The upper part of the outer surface of the round tube 12 is rotatably connected to a mounting block 11, and the right side of the mounting block 11 is rotatably connected to a round rod 10. The size of the round rod 10 is adapted to the arc groove 9, and the inside of the round tube 12 is plugged with a spray device body 16 through a piston.
[0029] The right side of the rotating rod 5 is fixedly connected with a pull rod 8, so that the staff can save more effort when rotating the rotating rod 5.
[0030] A first spring 7 is fixedly connected between the right side of the disk 6 and the left side of the first fixed plate 4. The first spring 7 is socketed with the rotating rod 5. By setting the first spring 7, a torsion can be provided to the disk 6 all the time, so that the disk 6 can be always in a normal state under the influence of the torsion of the first spring 7, and the circular tube 12 can be always in the inside of the mounting plate 3 when not affected by external force, so that the inside of the electromagnetic meter body 15 is in a sealed state.

At this time, the pull rod 8 drives the rotating rod 5 to rotate. After the rotating rod 5 rotates, the disc 6 fixedly connected to the rotating rod 5 and the arc groove 9 fixedly installed on the surface of the disc 6 will rotate synchronously in the positive direction.
