Abstract

A multifunctional softening valve and a water processing apparatus thereof. The multifunctional softening valve comprises a valve body, an ejector, a movable valve plate, a fixed valve plate, and a saline water control valve. The valve body is provided with a water inlet, a water outlet, a water drainage port, and a salt absorbing branch runner. The valve body is provided with a through-hole in communication with a filter element upper portion, a filter element lower portion and an ejector inlet. An ejector outlet is in communication with the filter element lower portion. The salt absorbing branch runner is provided with a saline water inlet. The saline water inlet is provided with a saline water control valve. The fixed valve plate is provided with a plurality of through-holes, and the through-holes are distributed according to a distribution mode of equally dividing the cross section of the fixed valve plate into six parts, and the movable valve plate is fitted to the fixed valve plate. In the present application, by means of the distribution of equally dividing the plane softening valve into six parts, water processing functions are implemented.

Claims

1. A multi-functional softener valve comprising:

a valve body, an injector, a moving disk, a fixed disk and a brine control valve, wherein;

the valve body is provided with an inlet, an outlet, a drain and a brine absorption branch of a flow channel, and is also provided with through-holes connected to an upper filter, a lower filter, an injector inlet, and an injector outlet;

wherein the injector outlet is connected to the lower filter such that water can pass from the injector outlet to the lower filter without contacting the fixed disk or moving disk;

a brine inlet is located in the brine absorption branch of the flow channel;

the brine control valve is located on the brine inlet;

a plurality of the through-holes are located in the fixed disk, and the through-holes are distributed in six equal sectors of a circular face of the fixed disk, wherein, on the circular face of the fixed disk, in a counterclockwise direction, a first through-hole and a second through-hole are connected to the upper filter with the upper filter being connected to the valve body, a third through-hole is connected to the lower filter, a fourth through-hole is connected to the outlet, and a fifth through-hole is connected to the injector inlet, a sixth through-hole is set in a center of the circular face of the fixed disk that is connected to a drain of the valve body;

the circular face of the fixed disk matches with a circular face of the moving disk; and

on the circular face of the moving disk, an inlet through-hole connected to the inlet of the valve body, a radial blind hole that is from a center to circumferential direction, and an arc-shaped blind hole are set.

2. The multi-functional softener valve of claim 1, wherein the matching relationship of the moving disk, the fixed disk and the brine control valve is as follows:

when the inlet through-hole of the moving disk is connected to the second through-hole of the fixed disk, the arc-shaped blind hole on the moving disk is connected to the third through-hole and the fourth through-hole of the fixed disk, the radial blind hole of the moving disk is only connected to the sixth through-hole of the fixed disk, and the brine control valve can be opened or closed;

when the inlet through-hole of the moving disk is connected to the third through-hole of the fixed disk, the arc-shaped blind hole of the moving disk is only connected to the fourth through-hole of the fixed disk, the radial blind hole of the moving disk is connected to the first through-hole and the sixth through-hole of the fixed disk, and the brine control valve is closed;

when the inlet through-hole of the moving disk is connected to the fifth through-hole of the fixed disk, the arc-shaped blind hole of the moving disk is only connected to the first through-hole of the fixed disk, the radial blind hole of the moving disk is connected to the second through-hole and the sixth through-hole of the fixed disk, and the brine control valve is opened;

when the inlet through-hole of the moving disk is connected to the first through-hole of the fixed disk, the arc-shaped blind hole of the moving disk is only connected to the second through-hole of the fixed disk, the radial blind hole of the moving disk is connected to the third through-hole and the sixth through-hole of the fixed disk, and the brine control valve is closed.

3. The multi-functional softener valve of claim 2, wherein the brine control valve comprises a ball valve, a solenoid valve, a check valve, a diaphragm valve or a gate valve.

4. The multi-functional softener valve of claim 1, wherein the injector inlet and the injector outlet are located in the brine absorption branch of the flow channel.

5. The multi-functional softener valve of claim 1, wherein the brine control valve comprises a ball valve, a solenoid valve, a check valve, a diaphragm valve or a gate valve.

6. A water treatment device comprising the multi-functional softener valve of claim 1, wherein the multi-functional softener valve is connected to a tank containing an cation exchange resin.
