Description

Technical Field

Background

The household softening system generally comprises a control system, an operation system and a regeneration system, wherein the control system comprises a control valve and an electric control program, the operation system comprises a softening filter material, a resin tank and a flow passage structure, and the regeneration system comprises a salt tank and a salt valve structure. The working principle is that hard water contacts with a softening filter material in a resin tank in a certain flow direction through a flow channel structure, calcium ions, magnesium ions and the like in the hard water are replaced through exchange reaction, and water softening is achieved. The filter material begins to lose effectiveness gradually from the water inlet direction of the resin tank to the water outlet direction until the water outlet is larger than a failure standard value. After the softened filter material is invalid, the filter material needs to be regenerated and recovered, softened salt in a salt tank is dissolved into saturated salt water, and a prepared regeneration liquid is injected into a resin tank to re-exchange adsorbed calcium and magnesium ions and discharge the calcium and magnesium ions so as to regenerate the filter material.

However, the utilization rate of sodium ions in the regeneration liquid in the actual regeneration process is constantly changed by the change of the regeneration conditions, and when the regeneration conditions deviate from the optimal working conditions, the utilization rate of sodium ions is reduced, so that the performance of the whole machine is reduced, the salt consumption is increased, and the regeneration efficiency is low.

The regeneration flow channel is used for guiding externally injected regeneration liquid into the softening system when the softening system is at a regeneration station so as to regenerate the softened filter material in the softening system (for example, a regeneration flow channel 19 in subsequent figures 7 and 8). Here, a plurality of regeneration flow paths are formed in the main valve body 5, and the flow areas of the regeneration flow paths which are conducted differently are different, that is, when the different regeneration flow paths are conducted, the flow rates of the regeneration liquid flowing through the regeneration flow paths are different, so that the flow rates of the regeneration liquid injected into the softened filter material storage container (resin tank 7) through the conducted regeneration flow paths are different. In other words, the flow rate of the regeneration liquid injected into the softened filter material storage container can be controlled by adjusting the conduction of different regeneration flow channels in the main valve body 5.

The driving assembly 1-4 is used for driving the regeneration flow channel adjusting assembly 3-16 to adjust. The drive assembly 1-4 may be understood as giving the regenerative flow path regulating assembly 3-16 a "force" to adjust it as required by the current application scenario. Specifically, the driving assemblies 1 to 4 may include a driving motor and a transmission unit, the driving motor rotates, the transmission unit applies an acting force to the regeneration flow channel adjusting assemblies 3 to 16, the driving motor may be a stepping motor, the driving unit may be a transmission gear, and the driving unit may be a plurality of stepping motors for coordinated driving to achieve precise adjustment.

Specifically, the regeneration flow channel adjusting components 3 to 16 can be understood as "switches" of each regeneration flow channel, when the regeneration flow channel adjusting components are turned on, the corresponding regeneration flow channel is conducted, and externally injected regeneration liquid enters the softened filter material storage container through the conducted regeneration flow channel and contacts with the softened filter material to realize regeneration; when the regeneration device is closed, the corresponding regeneration flow channel is closed, and externally injected regeneration liquid needs to enter the softened filter material storage container through other conducted regeneration flow channels.

Specifically, the jet flow channel adjusting sheet can move up and down to change the blocked jet flow channel and the communicated jet flow channel; the jet flow channel adjusting sheet can also be rotated, the jet flow channel adjusting sheet is provided with the flow channel hole, when the flow channel hole is opened, the corresponding jet flow channel is conducted, and when the flow channel hole is blocked, the corresponding jet flow channel is blocked.
