Abstract

The utility model discloses a valve with a filtering device convenient to replace, and relates to the technical field of valves. The valve comprises a valve body, a water inlet is fixed to one side of the valve body, and a water outlet is fixed to the side, away from the water inlet, of the valve body. A threaded groove is fixed to the end, close to the water outlet, of the valve body. A connecting rod is fixed to the inner wall of the threaded cover, and an installer is fixed to one end of the connecting rod. Under the action of the filter cartridge, the filter cartridge which can be flexibly disassembled is arranged in the device and is connected with the clamping structure of the installer through the installation shell, and the filter cartridge can be quickly disassembled without a tool only by rotating out a threaded cover and pressing a first handle to unlock clamping during replacement, so that the maintenance difficulty is remarkably reduced, and the operation time is shortened; the valve does not need to be integrally disassembled or integrated parts do not need to be replaced, only the filter cartridge needs to be independently replaced, material waste and accessory cost are reduced, and the filter device is particularly suitable for frequent cleaning or replacement of the filter device.
