a groove is arranged below the locking piece 10 and is used for being matched and connected with a second boss 72 above the handle 7 when the locking state is adjusted so as to drive the handle 7 to rotate; the locking piece 10 has magnetism, can suck the magnetic element 1 into the third counter bore 71, and adjusts the position of the magnetic element 1 relative to the valve body 2 through rotation so as to transfer the magnetic element 1 into the first counter bore 21 or the second counter bore 22, thereby controlling the locking and unlocking of the double-control valve;

in the locking state of the valve, the magnetic element 1 is positioned between the first counter bore 21 and the third counter bore 71, the handle 7 is clamped and further limited in rotation, and free switching cannot be performed; under the unlocking state of the valve, the magnetic element 1 is positioned in the second counter bore 22, and the handle 7 can freely rotate and further can freely switch, so that double control of the valve is realized.

Further, the number of the magnetic element 1, the first counter bore 21, the second counter bore 22 and the third counter bore 71 is equal and is respectively 2 to 6. When the number of the magnetic elements 1 is two, the first counter bore 21 and the second counter bore 22 are arranged at a 90-degree interval, and the locking piece 10 can be rotated by 90 degrees when locking or unlocking. When the number of the magnetic elements 1 is two, the N level of the left magnetic element 1 faces the handle 7, the S level faces the valve body 2, the S level of the right magnetic element 1 faces the handle 7 and the N level faces the valve body 2, so that the valve can be effectively prevented from being opened randomly.

As shown in FIG. 5, when the double control valve is in the locked and closed state, the center line of the handle 7 is in a state of being perpendicular to the center line of the double control valve by 90 degrees, the closing word on the boss 23 on the valve body 2 can be seen, 1/3 to 1/2 of the magnetic element 1 is positioned in the first counter bore 21 of the valve body 2, and the other 1/2 to 2/3 of the magnetic element 1 is positioned in the third counter bore 71 of the handle 7, so that the handle 7 is blocked and can not rotate. If rotation is needed, the locking piece 10 is placed above the handle 7, so that the magnetic element 1 is completely sucked into the third counter bore 71, the valve is opened after the anticlockwise rotation for 90 degrees, the locking piece 10 is taken away, the magnetic element 1 completely falls into the second counter bore 22 of the valve body, and at the moment, the valve is in an unlocking and opening state and can be freely opened and closed. As shown in fig. 6, when the double-control valve is in the unlocked and opened state, the center line of the handle 7 is parallel to the center line of the double-control valve, the second boss 72 on the single side of the handle 7 is also parallel to the center line of the double-control valve, and the long side or thick side of the handle 7 completely covers the "off" word, so as to realize the state indication of the valve.
