Description

A magnetic liquid level gauge

technical field

The invention relates to a magnetic liquid level gauge, which belongs to the field of machinery.

Background technique

Liquid level gauges are widely used to observe the liquid level inside containers or equipment. There are many types of liquid level gauges, including pressure level gauges, differential pressure level gauges, float level gauges, ultrasonic level gauges, glass tube type Level gauges and magnetic level gauges, etc. The magnetic liquid level gauge is made according to the principle of buoyancy and magnetic coupling, and has the direct-reading feature of local display. The magnetic column level gauge is the most widely used magnetic level gauge at present. It consists of a liquid level tube with a magnetic float inside, a connecting tube connected to the container, and a display panel with a magnetic column on the outside of the level tube. The magnetic flip column is a cylinder installed in the display panel, half of its outer surface is red and half is white. When the magnetic float moves up and down with the change of liquid level, the magnetic flip column can be flipped around the axis. When the magnetic float rises , the corresponding magnetic turning column turns from white to red and faces the display panel. When the magnetic float drops, the corresponding magnetic turning column turns from red to white and faces the display panel, thereby displaying the liquid level in the container.

When the liquid level in the container changes, the magnetic float will be impacted by the liquid flow, resulting in uneven force and easy to get stuck and rotate, resulting in the small cylinder of the magnetic flap not being able to turn over in time. The unflipped, which confuses the reading, has the disadvantage of not having a recovery device set. The liquid level indication of the liquid level gauge described in this patent adopts the pointer mode, which effectively solves the problem of confusion in the liquid level display of the magnetic flip column liquid level gauge.

Most of the existing magnetic liquid level gauges use magnetic flip columns to display the liquid level, and few have pointer type. In the magnetic level gauge market, most of them are magnetic flip columns, and pointer type magnetic level gauges are still rare. The practicability of the existing pointer patents is not satisfactory. The problems of high frictional resistance during the movement of the pointer and the possible horizontal inclination of the pointer are not considered and solved, and the single-function structural design is unreasonable and difficult to recover from failure. In view of this situation, this patent provides a liquid level gauge with stable pointer movement, small frictional resistance, multiple functions and modular assembly, which has the advantages of novel and simple structure, convenient installation and maintenance, and easy fault diagnosis.

The container liquid enters the liquid level gauge body 1 through the liquid level gauge connecting flange 17 and the connecting pipe 9, and encounters the obstruction of the floating ball guide cylinder 6, and the liquid flow changes its flow direction from horizontal to vertical downward. The liquid continues to flow into the liquid level gauge tube body 1 and gathers at the bottom of the liquid level gauge tube body 1 , and flows into the float ball guide tube 6 through the opening at the bottom of the float ball guide tube 6 . As the liquid level in the float guide tube 6 rises, the magnetic float 7 rises simultaneously under the action of buoyancy. At this time, the iron slider 12 arranged outside the liquid level gauge tube 1 is subjected to the magnetic force of the permanent magnet 21 in the magnetic float 7. Moving upward along the semicircular groove 16 on the guide plate 3, the scale indicated by the liquid level pointer 14 installed on the iron slider 12 also changes at the same time. When an external power supply is connected, as the iron slider 12 rises, the resistance in the loop will decrease and the output current will increase. Similarly, when the liquid level in the container drops, the liquid flows back into the container from the connecting pipe 9 of the liquid level gauge tube body 1, and the liquid level in the liquid level gauge tube body 1 drops, and the magnetic float 7 is affected by its own gravity and moves along with the liquid level. Downward movement, at this time, the iron slider 12 is moved downwards under the magnetic force of the magnetic floating ball 7, so that the scale indicated by the liquid level pointer 14 decreases. When an external power supply is connected, the resistance in the circuit increases and the output current decreases.

(5) It has the advantages of simple structure, convenient installation and maintenance, low manufacturing cost, accurate and sensitive measurement and long service life;

(6) The outer cover is made of transparent material, which has the characteristics of easy judgment of liquid level indication faults.
