The rotary body 300 is in transmission connection with the first valve element 200, and the first valve element 200 can be driven to move by controlling the rotation of the rotary body 300. The magnetic locking assembly 400 is arranged between the rotary body 300 and the valve body 100, the magnetic locking assembly 400 can be unlocked only by using a specific control member, the rotary body 300 can not be locked to rotate through the magnetic locking assembly 400, and further the first valve core 200 is prevented from moving, so that the gate valve can be prevented from being controlled randomly.

The second valve cartridge 600 is also capable of blocking the water flow passage 110, but is a one-way block. This is because the water of the water flow passage 110 has pressure, and can push the second valve cartridge 600 to move against the force of the first elastic member 700, and the second valve cartridge 600 is in an opened state under normal operation. When the pressure in the water flow channel 110 changes to generate backflow, the water flow direction changes, the water pressure pushes the second valve core 600 to move towards the valve body 100, that is, the force of the water pressure acting on the second valve core 600 is the same as the force of the first elastic component 700 acting on the second valve core 600, so as to push the second valve core 600 to move towards the valve body 100 and block the water flow channel 110 together, and automatic check is realized.
