Description

Technical Field

[0001] This utility model relates to a buried ball valve with anti-corrosion function, belonging to the field of ball valve technology. Background Technology

[0002] Currently, buried ball valves, due to their long-term underground installation, are frequently exposed to high humidity and highly corrosive soil conditions, making them prone to corrosion. This corrosion can lead to decreased sealing performance, shortened lifespan, and even equipment failure. Existing buried ball valves typically improve corrosion resistance through the use of anti-corrosion coatings or materials, but these methods still have limitations in practical applications. For example, the coating is susceptible to mechanical damage or chemical corrosion, which can cause it to fail.

[0003] A search of existing technologies revealed a Chinese patent (CN214466275U) disclosing a corrosion-resistant, multi-functional buried ball valve. This patent uses a cover on the outside of the ball valve, with absorbent cotton inside to prevent corrosion from affecting the valve body. However, in practical use, it was found that the cover opens from the side via a hinge, making maintenance and repair difficult after burial, increasing the complexity of maintenance.
