(3) When the magnetic control valve 100 needs to be switched from the locking state to the normal on/off state, the special key 60 is connected with the operating element 40, at this time, the third magnetic steel 72 and the fourth magnetic steel 73 on the special key 60 are aligned with the first magnetic steel 412 and the second magnetic steel 522 on the operating element 40 respectively, and the first magnetic steel 412 and the second magnetic steel 522 are pressed into the second mounting hole 113 and the third mounting hole 114 respectively through repulsive force, so as to unlock the operating element 40; simultaneously, the operation piece 40 is lifted along the axis of the valve rod, so that the limiting part 415 on the operation piece 40 is separated from the first limiting groove 112a, and then the operation piece 40 is rotated along the circumferential direction of the convex part 11, so that the limiting part 415 on the operation piece 40 is clamped into the second limiting groove 112 b; at this time, in the second limiting groove 112b, the operating member 40 can rotate relative to the protruding portion 11, and can normally open or close the magnetic valve 100.
According to the invention, when the magnetic control valve 100 is opened, the locking mechanism and the locking hole are arranged in a staggered manner, and it can be understood that a special key is not required in the closing process, so that the magnetic control valve is more convenient to operate and has a wide application prospect. Meanwhile, the above-mentioned magnetic control valve 100 can be freely opened/closed in a normal open/close state, and when malicious arrears or sudden conditions do not allow a user to freely open/close the magnetic control valve 100, the magnetic control valve 100 can be locked without using the special key 60.
