Description

Technical Field

[0001] This utility model relates to a combined switch valve tooling for wells. Background Technology

[0002] Valves in underground pipelines are often housed in pits (or wells) resembling small rooms for convenient operation, such as opening and closing sections of the pipeline or for maintenance. These pits facilitate regular inspection, cleaning, and unclogging, serving as crucial hubs within the underground pipeline network. Valve wells typically have square valve switches. Controlling the flow rate, opening, and closing of valves within the well usually requires personnel to enter and manually rotate the valves. This is both inconvenient and unsafe. When the valve well's inner diameter is small, personnel movement is restricted, making valve control difficult, labor-intensive, and inefficient. Furthermore, the confined space within the well often suffers from poor air circulation, insufficient oxygen, and the potential presence of harmful gases such as methane, coal gas, and high-temperature gases, posing a significant threat to personnel safety. While tools exist for operating valve wells, their length and the structure of the valves they open are relatively fixed, limiting their applicability to valves of varying depths and sizes.
