[0046] The other end of the unlocking key 12 is provided with a fourth magnet 1204. When the unlocking key 12 is fitted over the second protrusion 402, the fourth magnet 1204 can repel the second magnet 103 and cause it to exit the second locking hole. That is, the magnetic properties of the two opposite ends of the fourth magnet 1204 and the second magnet 103 are the same. When the fourth magnet 1204 and the second magnet 103 are aligned, the fourth magnet 1204 uses a repulsive force to push the first magnet 603 out of the second locking hole.

[0047] The unlocking key 12 has a slide rail 1205 in its middle. The plane containing the central axis of the slide rail 1205 is perpendicular to the plane containing the central axis of the first embedding groove 1201 and the plane containing the central axis of the second embedding groove 1203. The key lever 1206 slides within the slide rail 1205, and the position of the key lever 1206 can be adjusted as needed. Therefore, its use is less affected by the installation position.

[0048] like Figures 9 to 11 As shown, when the valve with filter disclosed in this utility model is in use, if the main valve core 2 and the drain valve core 604 are opened simultaneously, part of the fluid in the valve body 1 can enter the drain pipe 6 after passing through the filter pipe 5, and then be discharged from the drain pipe 6, thereby achieving the function of online sewage discharge and cleaning. When the drain valve core 604 is opened, the filter screen cover 10 can be removed for cleaning using a wrench, which is very convenient to use.
