Embodiment Construction

[0025] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0026] Such as Figure 1-Figure 4 As shown, the packaging structure of the electromagnetic flowmeter sensor built-in electrode and the lining provided by the present invention includes a lining 1, and the lining 1 is a cylindrical structure with two ends opened by polytetrafluoroethylene, and the inner wall of the lining 1 Two key grooves 101 are opened symmetrically on the top, and the key grooves 101 are opened along the axial direction of the liner 1 .

[0027] The keyway 101 is equipped with a flat key 2, and one end surface of the flat key 2 is provided with a groove along its axial direction, and a cavity is formed between the groove and the keyway 101, and the cavity is used for placing a lead wire.

[0028] At the same time, an installation hole 201 is opened in the middle of the flat key 2, the installation hole communicates with the cavity, and the...

Abstract

A sensor built-in electrode and a lining package structure for an electromagnetic flowmeter provided by the invention include a lining, wherein the inner side wall of the lining is provided with two key grooves, which are disposed along the axial direction of the lining; the key grooves are equipped with flat keys, and lead wires are disposed between the flat keys and bottoms of the key grooves; the flat keys are provided with mounting holes, the axis of the mounting holes is perpendicular to the axis of the key grooves, at the same time, electrodes are mounted in the mounting holes, and the electrodes are connected with the lead wires. Due to the structure of mounting the electrodes in the mounting holes provided in the flat keys, the application allows the electrodes to be directly embedded in the lining, so that the installation of the electrodes does not require sealing, thereby improving the overall compressive strength of the electromagnetic flowmeter.

Description

technical field [0001] The invention belongs to the technical field of flow measurement, and in particular relates to an electromagnetic flowmeter sensor built-in electrode and lining packaging structure. Background technique [0002] The domestic oil industry uses high-pressure water injection to exploit oil during oil extraction, and the flow measurement of high-pressure water injection uses the principle of magnetoelectric flow measurement. The advantage of this method in use is that it is convenient to disassemble and assemble, and is beneficial to maintenance. The disadvantages are: 1) the accuracy is generally not high, and 2) the electromagnet is easy to absorb magnetic impurities in the water, resulting in a decrease in measurement accuracy and blockage of the pipeline. [0003] The electromagnetic flowmeter has the advantages of high precision, good stability, high reliability, and long service life, and the inside of the lining is a through pipe that is not easy t...
