Technical Field

[0001] The utility model relates to the technical field of valves, in particular to a valve for a mixed bed. Background Art

[0002] In modern industrial production, mixed-bed systems play a vital role in water treatment, chemical engineering, and other fields. A mixed bed is a device that mixes cation exchange resins and anion exchange resins in a specific ratio and packs them into the same exchange container, effectively removing cations and anions from water. Valves, as key control components in mixed-bed systems, directly impact the overall system's performance and stability. Traditional mixed-bed valves have exposed numerous problems in practical applications. First, flow control accuracy is limited. Flow requirements vary across different operating phases of the mixed bed, such as regeneration, backwashing, and forward washing. Traditional valves struggle to achieve precise flow control, resulting in suboptimal operation of the mixed-bed system, impacting water treatment effectiveness and efficiency. Furthermore, unstable flow control can damage the resin and shorten the life of the mixed-bed. Furthermore, clogging is a serious problem.

[0003] The water treated in mixed beds often contains various impurities, such as resin particles and sediment. Traditional valves have limited filtering capabilities, making it easy for these impurities to enter the valves and cause blockages. Blockages not only affect flow control but can also damage the valves, increasing repair costs and downtime. Furthermore, the filter components of traditional valves are often difficult to remove and replace, making maintenance a significant challenge. Furthermore, the installation and maintenance of traditional mixed bed valves are cumbersome. Their connections are inconvenient, requiring significant time and labor to install. Furthermore, due to the complex valve structure and tight connections between components, disassembly and repair are difficult in the event of a malfunction. This not only impacts the normal operation of the mixed bed system but also increases operating costs for the company.
