The new installation structure and function characteristics of the magnetic float level gauge

The new installation structure of the magnetic float level gauge can withstand the impact of the gas phase and prevent ferromagnetic impurities from falling into the nozzle, which is mainly reflected in the new type of nozzle components. The lower part of the magnetic float level gauge extends into a small section inside the equipment. A slotted water seal structure is set on this section. When the valve actuator is in normal operation, no matter where the liquid level is, this structure Ensure that the lower connector of the level gauge is always filled with liquid phase. When there is a gas-phase impact, the gas phase always moves upward or diagonally upwards. In this way, the gas phase cannot replace the liquid phase in the lower connector and cannot enter the level gauge. The measurement room avoids the interference of bubbles on the measurement and the generation of turbulence.

　　The upper and lower connection pipes of the new installation structure are made of non-ferromagnetic stainless steel to avoid the connection pipe being magnetized by the strong magnetic field of the float. The upper nozzle slightly extends into the inside of the equipment, and the end of the pipe is beveled downward to prevent falling impurities from entering the interior. The lower nozzle is easier for impurities to fall in due to the upper slotted hole structure. The color quartz tube level gauge must be in The upper slotted hole structure is covered with a cover plate. As long as the angle of the bevel and the position and size of the cover plate are appropriate, it can prevent ferromagnetic impurities from entering the pipe and prevent the float from being stuck.

　　Because the conventional magnetic float level gauge has the above-mentioned problems in practical application, many devices and tank areas in chemical plants have replaced the applauded magnetic float level gauge with a quartz tube type level gauge. If it is a new installation structure, it can prevent magnetic disorder and float jamming. The gas solenoid valve can be used to replace the quartz tube level gauge. The overall effect is much better than the quartz tube level gauge. The new installation structure is adopted. It solves the two major problems of magnetic disorder and float jam that limit its application, which is equivalent to overcoming the weakness of the magnetic float level gauge, expands the scope of application of the magnetic float level gauge, and improves the level gauge's ability to adapt to process changes and special industrial and mining Ability, so that the magnetic float level gauge can work more reliably in a wide range of liquid level measurement occasions.
