Description

Technical Field

[0001] This utility model relates to a water softener, and more particularly to a valve body sealing structure for a water softener. Background Technology

[0002] In the current field of water treatment, hard water remains a significant challenge affecting both daily life and industrial production. Hard water, containing higher levels of soluble calcium and magnesium compounds, causes numerous inconveniences in daily life. For example, when used for washing, hard water reacts with detergents like soap to produce insoluble substances, reducing washing effectiveness and potentially leaving stains on clothing, thus shortening its lifespan. In the kitchen, hard water easily forms limescale on kettles, pots, and other cookware, making cleaning difficult and reducing heating efficiency, thus increasing energy consumption. Long-term consumption of hard water may also pose potential threats to human health.

[0003] As people become more aware of water safety, water softeners are gradually entering ordinary households. However, most water softeners on the market are medium to large-sized devices that take up a lot of space and have poor softening effects, making it impossible for many ordinary families to install them.

[0004] In current water softeners, the reversing valve cores mostly adopt a split structure, which is relatively complex, increases the complexity of manufacturing and assembly, and increases the size. At the same time, the existing valve cores use multiple end face seals, which require axial compression to achieve a seal. When the valve core moves axially, sealing problems are likely to occur.
