The invention provides a magnetic locking valve, and belongs to the technical field of machines. The magnetic locking valve solves the problem that an existing valve with a lock cannot be opened but through a special key. The magnetic locking valve comprises a water inlet end, a water outlet end and a valve body, wherein the inside of the valve body is a cavity. The inside of the valve body is provided with a ball core and a valve rod linked to the ball core. The upper end of the valve body is provided with a convex portion, the outer end of the valve rod extends out of the convex portion and is fixed axially, the side portion of the convex portion is provided with a positioning hole, the side portion of the valve rod is provided with an installation hole, the inside of the installation hole is provided with a spring and a magnetic block, the two ends of the spring abut against the bottom of the installation hole and the magnetic block respectively, the magnetic block abuts against the inner side wall of the convex portion, and when the valve rod rotates so that the installation hole can be right opposite to the positioning hole, the magnetic block falls into the positioning hole. The magnetic locking valve further comprises an unlocking handle capable of being connected to the convex portion in a sleeved mode and being linked to the valve rod, wherein a position, corresponding to the positioning hole, on the inner side of the unlocking handle is provided with a magnet, and the magnetism of the magnet is the same as that of the magnetic block. The magnetic locking valve has the advantages of being simple in structure, convenient to operate and the like.
