Description

Technical Field

[0001] This utility model relates to the technical field of integrated steel valve wells, specifically to a load-bearing, sealed integrated steel valve well. Background Technology

[0002] Valve wells are small, room-like structures installed in underground pipelines (such as fire hydrants, water supply, and natural gas pipelines) to facilitate the opening and closing of sections of the pipeline network or for maintenance work. They house equipment and facilitate regular inspection, cleaning, and unclogging of the pipelines, preventing blockages. Traditional valve wells are designed for variable loads and non-vehicle roadways, lacking sufficient load-bearing capacity. Furthermore, the top of the valve well must be 50mm-200mm above ground level. In the complex underground pipeline networks of the petrochemical industry, this is unavoidable on paved roads, and the elevated portion increases numerous uncontrollable risks. Additionally, traditional valve wells are prone to seepage of surface sewage, groundwater, and even toxic gases, leading to valve corrosion and even submersion. This hinders daily inspection and maintenance, significantly shortens the valve well's lifespan, and can cause internal equipment to malfunction, jeopardizing safe production. Given these shortcomings, it is necessary to design load-bearing, sealed, integrated steel valve wells. Utility Model Content
