[0027] As shown in Figs. 1 to 3 A structure of a filter valve with a magnetic lock device 3 according to an embodiment of the present application is illustrated. The filter valve includes a valve body 1, a ball valve 2 and a magnetic lock device 3. The valve body 1 includes an inlet portion 11, an outlet portion 12 and a branch portion 13. The inlet portion 11 is provided with a liquid inlet channel 111, the outlet portion 12 is provided with a liquid outlet channel 121, and the branch portion 13 is provided with a filter cavity 131. The liquid inlet channel 111, the filter cavity 131 and the liquid outlet channel 121 are sequentially connected. The filter cavity 131 is provided with a filter screen 132. Liquid can flow from the liquid inlet channel 111, pass through the filter screen 132 in the filter cavity 131 for filtration, and then flow into the liquid outlet channel 121, and finally flow out of the liquid outlet channel 121.

[0028] In particular, the end of the branch pipe 13 is detachably provided with a filter screen plug 133 to block the filter screen 132 in the filter cavity 131. The detachable structure can facilitate the opening of the filter cavity 131 for cleaning the filter screen 132, thereby ensuring the filtering effect of the filter screen 132 during long-term use. Preferably, at least one filter plug sealing ring 135 is arranged between the filter screen plug 133 and the branch pipe 13 to prevent liquid from leaking out of the filter cavity 131.

[0029] Specifically, the ball valve 2 comprises a valve ball 21 and a valve rod 22. The valve ball 21 is rotatably arranged in the liquid inlet channel 111. The valve ball 21 is provided with a valve ball through hole 211. The valve rod 22 is drivingly connected with the valve ball 21 to control the communication and isolation between the valve ball through hole 211 and the liquid inlet channel 111. When the valve ball through hole 211 communicates with the liquid inlet channel 111, liquid can pass through the valve ball through hole 211 smoothly. When the valve rod 22 is rotated to make the valve ball through hole 211 not communicate with the liquid inlet channel 111, liquid cannot pass through, thereby realizing the opening and closing of the valve.

[0030] Preferably, the ball valve 2 further comprises a valve ball sealing ring 23 and an elastic gasket 24. The valve ball sealing ring 23 is arranged on both sides of the valve ball 21. The elastic gasket 24 is arranged outside the valve ball sealing ring 23. In this way, it can be effectively ensured that liquid can only flow through the valve ball through hole 211, thereby improving the sealing performance of the valve ball 21. More preferably, the outer periphery of the branch pipe 13 is rotatably provided with a date ring 134. The date ring 134 is provided with a plurality of scales. The date ring 134 is periodically rotated to record the cleaning time, thereby ensuring the filtering effect of the filter valve.

[0031] More specifically, the magnetic lock device 3 comprises a magnetic lock body 31, a lock head rotating plate 32, a lock head cap 33, and a rotating cap key 34. The magnetic lock body 31 is arranged on the inlet portion 11 and sleeved on the valve rod 22. The lock head rotating plate 32 is rotatably arranged on the magnetic lock body 31 and clamped with the valve rod 22. A plurality of installation cavities 35 are arranged between the magnetic lock body 31 and the lock head rotating plate 32. Some of the installation cavities 35 are provided with a spring 36 and a first magnet 37 arranged on the spring 36. The lock head cap 33 is clamped on the lock head rotating plate 32. The rotating cap key 34 is detachably clamped on the lock head cap 33. The rotating cap key 34 is provided with a second magnet 38 which is opposite to the first magnet 37 in position and has opposite magnetic properties. At least one valve rod sealing ring 25 is arranged between the valve rod and the magnetic lock body 31, thereby further improving the sealing performance between the ball valve 2 and the magnetic lock device 3.

[0032] In particular, the mounting cavity 35 comprises a mounting slot 351 and a locking slot 352, the mounting slot 351 is arranged at the top end of the magnetic lock body 31, the locking slot 352 is arranged at the bottom of the lock head rotating plate 32, the spring 36 is arranged in the mounting slot 351, the first magnet 37 is arranged on the spring 36, and the first magnet 37 can be clamped in the locking slot 352 under the action of the spring 36 to lock and fix the lock head rotating plate 32.

[0033] It is worth mentioning that the lock head cap 33 is provided with a clamping block 331, the rotating cap key 34 is provided with a clamping groove 341 corresponding to the shape of the clamping block 331, when the clamping groove 341 is clamped on the clamping block 331, the first magnet 37 corresponds to the second magnet 38. Preferably, the valve rod 22 is protrusively provided with a valve rod control head 221, the lock head rotating plate 32 is protrusively provided with a rotating plate control head 321, the valve rod control head 221 is clamped in the rotating plate control head 321, and the rotating plate control head 321 is clamped in the clamping block 331.

[0034] It should be understood that when the rotating cap key 34 is clamped on the lock head rotating plate 32 in the correct position, the second magnet 38 corresponds to the first magnet 37, the first magnet 37 is separated from the locking slot 352 under the repulsive force of the second magnet 38, so that the lock head rotating plate 32 can be rotated; when the rotating cap key 34 is separated, the first magnet 37 is clamped into the locking slot 352 again under the action of the spring 36 to lock and fix the lock head rotating plate 32 again.

[0035] In particular, the lock head rotating plate 32 is provided with a stroke slot 322, and the magnetic lock body 31 is protrusively provided with a limiting block 311 at the top, the limiting block 311 is clamped in the stroke slot 322, and the limiting block 311 and the stroke slot 322 are used to limit the rotating stroke of the lock head rotating plate 32, so that the alignment is more accurate.

[0036] It should be understood that the number and position of the magnets and the mounting cavity 35 shown in the application are only examples, and different numbers and positions of the mounting cavity 35 and the magnet can be customized according to customer needs, so as to design different unlocking settings, improve the difficulty of unauthorized personnel operating the valve, and further improve the safety of the filter valve.
