Two-position four-way electromagnetic reversing valve

If the solenoid valve coil is in a high temperature state for a long time, it will be quite unfavorable to the equipment, it will burn out, and in serious cases, it will also cause safety accidents. People need to pay more attention to this and take active precautions to prevent accidents.

When the coil of the solenoid valve is energized, the iron core is attracted to form a closed magnetic circuit. That is, when the inductance is in the maximum state, it will be timed. Its heating is normal, but the iron core can't be smoothly attracted when it is electrified, and the inductance of the coil decreases, the impedance decreases and the current increases accordingly, which leads to the excessive current of the coil, which affects its service life, so oil pollution, impurities, deformation, etc. hinder the iron core's activity, and it can't even be completely attracted normally when it is electrified, so that the coil is often in a state of less impedance than normal when it is electrified, which is the factor that leads to the coil heating.

Solution:

1. In order to avoid overheating of the solenoid valve coil, it is necessary to repair the inner wall with multi-hydraulic check valves, and the aged parts should be replaced in time, so as to ensure its working sensitivity.

2. The electromagnetic starting valve needs to be reformed, and the main method is to take out the internal spring, so that the gravity of the valve core can provide gravity, which not only effectively reduces the water pressure on the solenoid valve coil, but also prolongs the service life of the sealing parts. People must actively avoid overheating of solenoid valve coil, otherwise it will cause serious consequences.
