A valve device
By setting a connecting channel and a flow-blocking surface between the flow-blocking part and the filter element in the valve device, the backflow of impurities is blocked, which solves the problem that impurities are easy to flow back with the fluid and improves the filtration efficiency and impurity collection efficiency.

AI Technical Summary
Technical Problem
In existing valve devices, impurities are easily backflowed with the fluid during the filtration process, resulting in poor filtration performance.
Method used
A flow-blocking section is provided in the valve device to connect the flow-blocking section and the filter element. The flow-blocking section has a flow-blocking surface facing the impurity receiving cavity to prevent impurities from flowing back and improve the filtration effect.
Benefits of technology
By blocking the backflow of impurities through the baffle surface, the filtration efficiency and impurity collection efficiency of the valve device are improved, thus enhancing the filtration effect of the valve device.
