The CT room lead door is a radiation protection device designed for medical radiology, industrial flaw detection and other scenarios. Its core adopts a high-purity lead plate shielding layer, combined with an intelligent drive system and multiple safety protection mechanisms, while ensuring radiation safety isolation, it provides an efficient and silent passage experience
Core technical parameters
Radiation protection performance
Lead equivalent: standard configuration ≥2mmPb (supports 1-6mmPb customization), shielding rate of 80-150kV medical X-rays ≥99.9%
Leakage control: The door gap adopts a three-order maze structure + lead silicide sealing strip, and the leakage dose rate is <0.25μSv/h
Material structure: 1.5mm cold-rolled steel frame (optional 304 stainless steel), internal tic-tac-toe reinforcement, surface antibacterial coating (resistant to alcohol scrubbing >2000 times)
Drive and control system
Motor: 24V DC brushless motor (0.4-0.75kW), noise ≤45dB (A weighted)
Speed adjustment: 10-20cm/s stepless speed change, start-stop buffer <2cm
Safety protection design
Active anti-pinch system
8-beam infrared light curtain on both sides (detection height 5-180cm, response time <0.1 second)
Flexible sensing edge strip at the bottom (trigger pressure ≤5kg, rebound immediately when encountering resistance)
Emergency guarantee
Power-off manual release force ≤100N, standard mechanical emergency pull rod
Built-in fault diagnosis chip (LED screen displays E01-E20 fault codes in real time)
Customized configuration options
Dimensions: Suitable for door openings 0.9×2.1m to 2.4×2.8m (non-standard customization beyond the specification)
Opening method: sliding (embedded track) or 90° flat opening (airtight hinge)
Extended functions: lead glass window (≥8mmPb), access control system, ultraviolet disinfection module
Certification and service guarantee
Authoritative certification: Medical device registration certificate (Class II), CE EN61331-1, Radiation Safety License
Durability Commitment: Lead attenuation <3% after 100,000 opening and closing tests, rail wear ≤0.2mm
Maintenance System: 3-year warranty for core components, quarterly protective dose testing (JJG 774-2022 standard)
Typical Applications
Hospital CT/DR room, interventional catheter room, dental panoramic room, industrial X-ray inspection area
Selection Recommendations:
Door opening size, equipment tube voltage, daily traffic flow parameters are required, and engineers will customize radiation optimization solutions.
