[0024] The permanent magnet block 8 is arranged in the mounting groove and is adsorptively connected with the bottom wall of the mounting groove, the tail part 7 is arranged on the upper surface of the permanent magnet block 8 and is fixedly connected with the permanent magnet block 8, the electromagnetic valve 9 is arranged in the equipment shell 1, the electromagnetic valve 9 comprises an electromagnetic coil 10, an inner iron core 11 and a limiting gasket 13, the inner iron core 11 is provided with a containing cavity 12, the electromagnetic coil 10 is arranged in the containing cavity 12, the limiting gasket 13 is arranged between the upper end surface of the inner iron core 11 and the permanent magnet block 8, when the electromagnetic coil 10 is not electrified, the adsorption force between the permanent magnet block 8 and the bottom wall of the mounting groove is greater than the adsorption force between the permanent magnet block 8 and the inner iron core 11, so that the valve rod 5 blocks the channel 3, when the electromagnetic coil 10 is electrified, the electromagnetic valve 9 adsorbs the permanent magnet block 8 to overcome the adsorption force between the permanent magnet block 8 and the bottom wall of the mounting groove, so that the valve rod 5 opens the channel 3.

[0025] Further, the limiting gasket 13 is annular, the inner edge of the limiting gasket 13 is upwardly provided with a boss 14, the inner iron core 11 is provided with a groove, the boss 14 is in interference fit with the groove, and the size of the limiting gasket 13 and the distance between the limiting gasket 13 and the permanent magnet block 8 can be set according to actual needs.

[0026] Further, the spring 15 is arranged between the inner iron core 11 and the permanent magnet block 8, the spring 15 can exert pressure on the permanent magnet block 8 to assist the valve rod 5 in blocking the channel 3 and stably opening the channel 3.

[0027] Further, the equipment shell 1 is provided with an inlet 19 on one side surface and an outlet 20 on the other side surface.

[0028] Further, the permanent magnet block 8 is provided with a connecting hole, and the tail part 7 of the valve rod 5 is in interference fit with the connecting hole.

[0031] In use, when the electromagnetic coil 10 is powered, the electromagnetic coil 10 and the inner core 11 jointly generate an electromagnetic field opposite to the magnetic pole of the permanent magnet block 8 to adsorb the permanent magnet block 8, and by controlling the size of the current in the electromagnetic coil 10, the size of the suction force of the electromagnetic valve 9 and the permanent magnet block 8 can be adjusted. The limiting gasket 13 has no magnetic conductivity, so that the permanent magnet block 8 and the inner core 11 maintain a certain distance, avoiding the two from being attracted together, because the suction force is larger after being attracted together, it is difficult to separate, at the same time, avoiding the permanent magnet block 8 from directly colliding with the inner core 11, which is beneficial to protect the inner core 11 and the permanent magnet block 8. When the electromagnetic coil 10 is not powered, the adsorption force between the permanent magnet block 8 and the bottom wall of the mounting groove is greater than the adsorption force between the permanent magnet block 8 and the inner core 11, so the valve rod 5 will block the channel 3.

Considering that the pressure regulating valve is in a closed state most of the time, it only needs to be opened for a short time when adjusting the pressure, therefore, the pressure regulation of the above-mentioned structure can maintain high pressure without providing power to the electromagnetic coil 10 in most cases. Compared with the prior art, which needs to continuously provide power to maintain high pressure, while ensuring the reliability of pressure regulation, it can reduce power consumption, save energy, and reduce costs. At the same time, there is no need to worry about the problem of the electromagnetic coil 10 being damaged by continuous power supply due to heating, which prolongs the service life of the above-mentioned pressure regulating valve.
