1results about How to "Affect the sealing effect" patented technology

This invention relates to the field of underground gas storage technology for compressed air energy storage power stations, specifically to a large-size sealed door structure for high-pressure underground gas storage. It includes a sealed door, a sealing ring fixing steel plate, a first sealing ring, and a second sealing ring. A maintenance passage is provided inside a reinforced concrete plug. The sealed door is connected to the reinforced concrete plug via a sealing door support hinge. The maintenance passage is connected to the gas storage through the sealed door. The sealing ring fixing steel plate is fixed between the sealed door and the reinforced concrete plug. Both the first and second sealing rings are interference-fitted between the sealing ring fixing steel plate and the sealed door, with the first sealing ring positioned outside the second sealing ring. The sealed door structure is simple, adaptable to complex operating conditions, and ensures durability and reliability. It employs conventional sealing methods to form two seals, creating a double-layered protective barrier, resulting in good sealing performance, simple maintenance, and low repair costs.
