Description

This invention relates to pipe fittings.

The aim of the invention is to improve the reliability of holding ferromagnetic materials by installing magnetic flux concentrators.

FIG. 1 shows an electromagnetic gap, a section; FIG. 2 the same, top view.

Electromagnetic gap includes an electric coil 1, covering channel 2 made of non-magnetic material for the passage of ferromagnetic material. On the outer side of coil 1 there are permanent magnets 3 and 4 on the ends of which there are ferromagnetic magnetic cores 5 and 6 in the form of horseshoe-shaped plates, the inner edges of which are made along the radius of the passageway 2. In channel 2, there are installed ferromagnetic plates 7 and 8 directed along the generator of the channel opposite to each other, attached to the inner edges of the vertices below cobbled. Ylastin 5 and 6,

The shutter works as follows.

With the electric coil 1 turned off, the material in the gate channel is held due to the interaction with the constant magnetic field.

5 magnets 3 and 4. When a constant voltage is applied to an electric coil 1 inside channel 2, a resultant magnetic field is created, equal to the geometric sum of the fields

10 permanent magnets and electric coil. When applied to an electric coil 1, a constant voltage polarity, in which the magnetic field of coil 1 is directed

15 against the magnetic field of the permanent magnets 3 and 4, the resulting magnetic field decreases and the shutter opens. When the magnitude of the voltage applied to the electric coil varies, the capacity of the gate changes.

When the electric coil is disconnected due to the presence of ferromagnetic plates 7 and 8 in the channel

25, the magnetic field in the channel, created by permanent magnets, orients pyetc in a direction close to the horizontal, which leads to effective coupling of the particles of ferromagnetic material to one another.
