Background Art

The mud valve well generally adopts a vertical shaft water discharge project, which consists of a mud discharge pipe and a vertical shaft. A maintenance valve is installed in the vertical shaft. The traditional mud valve well uses a gate valve or a pressure gauge to determine whether the water pipe is blocked, so as to perform maintenance to ensure the normal operation of the system.
