Description

Technical Field

[0001] This utility model relates to the field of nuclear magnetic resonance protection technology, specifically to a structure for a radiation-proof depressurization gas fire extinguishing door. Background Technology

[0002] Radiation shielding doors are specialized protective devices designed specifically for shielding ionizing radiation. They are widely used in high-risk locations such as hospital radiology departments, nuclear power plants, industrial flaw detection facilities, and research laboratories. Their core structure utilizes high-density shielding materials, such as lead plates, lead composite plates, or boron-containing polyethylene, effectively attenuating radiation intensity through physical blocking to ensure the safety of surrounding personnel and the environment. The doors are typically designed for electric or manual opening and are equipped with a radiation interlock system that automatically cuts off the radiation source when the door is not closed, preventing accidental operation. Traditional radiation shielding doors are usually fully enclosed, which conflicts with fire pressure relief requirements. In emergencies, this may affect pressure relief efficiency, failing to meet fire pressure relief needs. Furthermore, conventional fire pressure relief doors cannot meet radiation protection requirements. Utility Model Content
