Abstract

The invention discloses a valve, a control method of the valve, a water filtering device and a control method of the water filtering device, and relates to the technical field of control valves. The valve comprises a shell, an isolation piece, a first open hole and a transmission piece, a flow channel opening is formed in the shell, the isolation piece can block the flow channel opening, a back pressure cavity is formed between the side, away from the flow channel opening, of the isolation piece and the shell, a second open hole is formed in the isolation piece, the first open hole communicates with the back pressure cavity, the transmission piece can drive the isolation piece to move and can block the second open hole, the valve has at least three states, wherein in the first state, the transmission piece blocks the second open hole, and the isolation piece blocks the flow channel opening; in the second state, the second open hole is in an open state, and the isolation piece blocks the flow channel opening; and in the third state, the transmission piece drives the isolation piece to be separated from the flow channel opening. According to the valve, the control method of the valve, the water filtering device and the control method of the water filtering device, the requirements on various flows can be met on the premise of low cost.

Description

technical field [0001] The invention relates to the technical field of control valves, in particular to a valve and a control method thereof, a water filtering device and a control method thereof. Background technique [0002] With the continuous upgrading of the water purifier system, in order to further improve the service life of the filter unit in the water purifier, the filtering effect and avoid problems such as TDS rise, it is not only necessary to set a valve with the function of wastewater ratio at the wastewater end of the filter unit, or It is necessary to be able to control the disconnection and opening of the waste water side of the filtration unit. Therefore, in the prior art, two solenoid valves are usually connected in parallel or in series to realize the above three functions, and the above two solenoid valves can also be integrated into one valve. Although the latter method seems to use one valve, but the internal principle of the valve is basically simila...
