Abstract
The utility model relates to an electromagnetic float level regulator, comprising a float chamber, a floating ball, a float rod, a stop frame, a flange, an elastic membrane, a regulating screw, etc. The key point of the utility model is that the front part of the regulating screw is provided with a button-shaped permanent magnet and a dry reed pipe is fixed under the magnet and on the flange. The vertical displacement of the floating ball because of the buoyancy is transmitted to the permanent magnet through the float rod. The magnet does the straight-line motion, and the magnetic line of the magnet acts on the inner joint of the dry reed pipe to carry out the alarm and the control of the pump. The utility model has the advantages of reasonable structure, reliable running and long service life. The dry reed pipe is sealed and is used as an explosion-proof switch.
Description
The utility model belongs to liquid automatic control Design of device and manufacturing technology field.
Existing UQK-21 type mechanical switch ball float level controller, the liquid level that is used for the media such as water, oil, sulfuric acid of container is regulated, indication and warning, is used in combination with electromagnetic starter.Automatically start electric pump during the ball float levitating and carry out the liquid level adjusting.Adjustable range-5～+ 30 millimeter, pressure 0.6～1.2MPa, temperature are not higher than 200 ℃.Its structure as shown in Figure 1.Liquid level changes generation buoyancy ball float (2) in the container, makes it produce vertical displacement, and this displacement reaches through fly rod (3) and adjusts screw (8), remakes the contact that is used for sensitive switch (9), and switching signal takes place.The shortcoming of this fluid level controller is that in the occasion that is being used for the frequent adjusting of liquid level, sensitive switch inner spring sheet is fragile, just need change sensitive switch in 2～3 months.Maintenance load is big, and reliability is low.
The purpose of this utility model is that the shortcoming at existing fluid level controller provides a kind of rational in infrastructure, the electromagnetism ball float level controller of long service life.
Structure of the present utility model as shown in Figure 2.Ball float 2 is housed in the float chamber 1, and ball float is connected with spring diaphragm 6 and adjustment screw rod 7 by fly rod 3.Spring diaphragm 6 is fixed on the flange 5, forms balance pivot.In adjustment screw rod 7 front portions button-type permanent magnet 8 is housed, is fixing a tongue tube 9 below the button-type magnet 8, on flange 5.
Its operation principle is:
Liquid level in the float chamber changes generation buoyancy, acts on ball float and makes its vertical displacement, and this displacement is passed to the button-type permanent magnet through fly rod, the button-type permanent magnet moves both vertically, its magnetic line of force acts on the tongue tube interior contacts, thereby switching signal takes place, and reaches the purpose of warning and control of pump.
Sort controller is mainly used in the control of liquid levels such as water in the container, oil, acid.
The utility model has been tried out on the high-temperature residual heat apparatus for recovering of three factories, and control of pump is sent water toward boiler, has used more than 1 year, and operating state is still good.
The utility model has the advantages that simple in structure, control is sensitive, and is reliable.Compare long ten times of life-span with mechanical fluid level controller.Because tongue tube seals, and has also played the effect of flame-proof switch.
