The control valve and the movable disk thereof according to the embodiment of the present invention are described below with reference to fig. 1 to 7. It is understood that the water softener adsorbs metal cations such as calcium and magnesium in water through the resin in the water softener so as to achieve the purpose of softening the water. After the resin is saturated, calcium and magnesium ions on the resin are replaced by softened salt water, so that the resin is regenerated, and the adsorption capacity is recovered. The water flowing in the water softener comprises raw water, soft water, brine, sewage and the like, the waterway is complex, and the control valve is used for controlling the water flowing in the water softener.

The control valve 100 is communicated with the resin tank and the salt tank, and the control valve 100 is used for controlling the flow direction and the flow rate of water so as to enable the water to flow to corresponding positions and realize corresponding functions. For example, the control valve 100 may control the inflow of water from the inlet of the resin tank to filter the water to provide soft water; or the control valve 100 may control the inflow of water from the outlet of the resin tank to flush the resin, remove broken resin, and increase the gaps between the resin particles; when the salt in the salt tank is insufficient, the control valve 100 may replenish water to the salt tank to dissolve the salt in the salt tank to form salt water.

Referring to fig. 1 and 2, a control valve 100 according to an embodiment of the present invention includes a valve body 110 and a movable disk 120.

Specifically, the valve body 110 is provided with a water inlet pipe, a valve cavity 111, and at least one water channel, the valve cavity 111 is communicated with the water inlet pipe, the water inlet pipe is suitable for being communicated with a water source, the water channel is communicated with the valve cavity 111, and the water channel is used for conveying water into the resin tank or the salt box. The movable disk 120 is attached to the communicating part of the valve cavity 111 and the water channel, at least one water through hole 121 is formed in the movable disk 120, the water through hole 121 is used for communicating the water channel and the valve cavity 111, water flows into the valve cavity 111 through the water inlet pipe, and water in the valve cavity 111 can flow into the water channel through the water through hole 121 to be conveyed into the resin tank or the salt tank.

For example, the plurality of water channels comprise a tank inlet water channel and a water supplementing water channel, the tank inlet water channel is communicated with a tank inlet of the resin tank, and the water supplementing water channel is communicated with the salt tank. When the water through hole 121 is communicated with the tank water inlet channel, the water inlet pipe, the valve cavity 111, the water through hole 121 and the tank water inlet channel jointly define a tank water inlet channel, and water is conveyed into the resin tank through the tank water inlet channel to be filtered so as to form soft water, so that the soft water is provided for a user; when the water through hole 121 is communicated with the water replenishing water channel, the water inlet pipe, the valve cavity 111, the water through hole 121 and the water replenishing water channel jointly define a water replenishing water channel so as to replenish water for the salt tank.

Referring to fig. 3 and 4, according to the movable disk 120 of the control valve of the embodiment of the present invention, at least one water through hole 121 is provided on the movable disk 120, the water through hole 121 penetrates the movable disk 120 in the thickness direction of the movable disk 120, and the water through hole 121 is used for communicating the valve cavity 111 and the water channel so as to convey water in the valve cavity 111 into the corresponding water channel. The water through holes 121 may be plural, and the plural water through holes 121 are distributed at intervals along the circumferential direction of the movable disk 120.
