At this point, insert the electronic key into the lock cylinder, and after authentication, the lock can be unlocked. Then remove the electronic lock from the valve to operate the valve.

[0063] The working principle of this utility model is as follows: The magnetic particles installed in the four magnetic particle holes of the magnetic particle key 1500 have opposite polarities to the four corresponding magnetic particles on the lock body. Therefore, when the magnetic particle key 1500 is inserted into the unlocking cavity 307, the four magnetic particles on the lock body will retract into the holes, thus unlocking the dust cover 300. After the dust cover is unlocked and rotated, the electronic key is inserted into the lock cylinder. After authentication, an unlocking command is sent to the main control circuit board 900. The main control circuit board 900 executes the command to supply power to the coil body 700, and the moving iron core 800 retracts, thereby realizing the unlocking.
