Description

Multi-way valve, fixed valve plate and water softener

Technical Field

The invention relates to the technical field of water treatment, in particular to a multi-way valve, a fixed valve plate and a water softener.

Background

At present, a tap water source used in cities is usually collected from underground water, but the underground water usually contains angled calcium ions and magnesium ions, so that water is easy to scale in the using process, and further the damage of an electric appliance is caused, hard water is softened, lithiasis can be effectively prevented, the burden of heart and kidney is relieved, the health of people is benefited, meanwhile, the damage of the electric appliance caused by excessive scale accumulation is avoided, and therefore the water softener capable of softening the hard water is used more and more frequently in life.

The water softener usually exchanges calcium and magnesium ions in water through functional ions on resin, so that redundant calcium and magnesium ions in water are adsorbed, and the aim of removing scale is fulfilled. The water softener among the prior art includes integrated water route and connects water softener and the confession salt device on integrated water route usually, and during the raw water got into water softener through integrated water route, the resin layer among the water softener can soften the raw water and export the soft water through integrated water route for the user to use. When all the resins are fully adsorbed with calcium and magnesium ions, the water softener can not soften tap water any more, and at the moment, backwashing regeneration needs to be carried out on the exchange resins. After the salt in the salt supply device is dissolved and saturated by the injected water, the saturated salt solution soaks the resin, so that a large number of sodium ions in the saturated salt solution replace calcium and magnesium ions adsorbed on the resin. When calcium and magnesium ions are replaced, the resin achieves the effect of reduction and regeneration, and the next water softening work is prepared.

In the existing water softener, the multi-way valve is used as a core component for controlling the flow direction of water in the integrated water channel, and water flow can be controlled to flow in different structures in different directions by controlling the multi-way valve to be switched in different stations, so that the functions of water supply, backwashing, regeneration, water replenishing and the like are realized, and therefore, waste water generated by cleaning resin and raw water to be softened are collected in the multi-way valve.

However, in the integrated water channel, the multiple flow paths in the multi-way valve need to be butt-jointed with the flow paths in the water softener and the salt supply device, and the existing multi-way valve is unreasonably arranged, so that the water softener or the salt supply device is unreasonably arranged in the water softener and distributed in space, and therefore the multi-way valve with a reasonable structure needs to be designed so as to be better connected with other devices in the water softener.
