Description

Technical Field

[0001] The utility model relates to the technical field of electromagnetic flowmeters, in particular to an electromagnetic flowmeter which is easy to install and maintain. Background Art

[0002] The electromagnetic flowmeter is a new type of flow measurement instrument that has developed rapidly with the development of electronic technology. The electromagnetic flowmeter is an instrument that uses the principle of electromagnetic induction to measure the flow rate of conductive fluid based on the induced electromotive force when the conductive fluid passes through an external magnetic field.

[0003] Publication No. CN220625393U discloses an electromagnetic flowmeter that is easy to maintain the sensor. The patent moves the sensor head upward by loosening the flange between the pipeline and the flowmeter body, and then rotates the fixing assembly to loosen the connection between the sensor head and the connecting tube. Then, the edge block is pushed downward by the action of the spring. The edge block drives the sensor head to move downward through the limit block, so that the sensor head leaves the connecting tube, thereby realizing its disassembly. When it needs to be installed, it only needs to be operated in the opposite direction. By setting the above structure, it is convenient to disassemble and assemble the sensor, and solves the problem that the converter and the sensor in the existing electromagnetic flowmeter are generally integrated, and this type of connection is inconvenient for maintenance. However, the patent still has the following problems in actual use:

[0004] By setting up a fixed component, it is convenient to disassemble and assemble the sensor, and the problem that the converter and sensor in the existing electromagnetic flowmeter are generally integrated is solved. This type of connection is inconvenient for maintenance. However, in actual use, when disassembling the sensor head, it is necessary to continuously turn the screw, which is inconvenient for the disassembly of the sensor head. When installing the sensor head, it is necessary to squeeze the spring. After squeezing the spring, the spring has a certain reaction force. The user needs to hold the sensor head to prevent the spring from recovering its deformation and align the notch with the screw. The installation process is more laborious and not convenient for quick installation and disassembly.

The overall structure is simple, which is convenient for users to operate and improves convenience and practicality. The specific contents are as follows:

[0020] 1. An installation assembly is set between the flow meter body and the sensor. When repairing and maintaining the sensor, the fixing cap is removed from the pipe, and then the movable ring can be moved downward. After the movable ring is moved downward, the mounting block can be pulled by the connecting rod to move, and then the limit rod can be driven to slide on the fixed tube. While the limit rod is moving, the reset spring can be stretched to disengage the limit rod from the limit groove. The telescopic spring can restore its deformation in a compressed state, so that the sensor can be pushed out to complete the disassembly of the sensor. When installing the sensor, insert one end of the sensor into the interior of the fixed tube. Since one end of the sensor is chamfered, the sensor can be moved after contacting the limit rod. By pushing the limit rod to move, the top of the sensor contacts the fixed block and continues to move the sensor to compress the telescopic rod and the telescopic spring, so that the limit groove on the sensor is aligned with the limit rod, and the reset spring recovers its deformation, so that the limit rod and the limit groove are engaged to position the sensor, and the sensor can be quickly disassembled and assembled. After the sensor is installed and subjected to the internal pressure of the pipeline, the movable ring can be pushed upward. After the movable ring is subjected to the upward thrust, the limit rod is not easy to be separated from the limit groove. The installation assembly is convenient for users to quickly disassemble the sensor, which is convenient for later repair and maintenance. The overall structure is simple, which is convenient for users to operate, and improves convenience and practicality.

[0021] 2. Two sets of positioning components are symmetrically arranged on one side of the fixed cap at the top of the pipeline. When maintaining the flow meter body, the U-shaped frame can be pulled to drive the movable block to slide on the movable rod, so that the movable block squeezes the compression spring and the positioning block is disengaged from the positioning groove. Then, the movable block and the movable rod are rotated by the U-shaped frame to stagger the movable block and the fixed cap. Then, the fixed cap loses its limit and can be removed. Otherwise, the fixed cap can be positioned, and the compression spring is in a compressed state, which can provide downward pressure on the fixed cap. The first sealing gasket and the second sealing gasket are used to ensure the sealing of the fixed cap installation, which facilitates the disassembly and assembly of the fixed cap and improves its practicality.
