One. Shielding Effect: Ensuring Employee Doses Reach National Regulatory Target Levels.

Safety Requirements: Equipped with position sensors and infrared detectors. If a person approaches or touches the door during the closing process, the door will stop closing and automatically open. It features travel, limit, and timing protection functions.

III. Control Requirements: The door switch can be controlled by a computer, button, and manually. It supports bus interfaces, displays the door status on the computer, and shows the operational status with an LED on the door.

Four. Interlock Function: The protective door is interlocked with the power supply of the radiation device. The ray machine cannot be opened when the door is opened. If the protective door is opened when the radiation device is activated, it will close immediately within 2 seconds.

Principle of Lead Door Operation

Principle and Structure of Lead Door: The door frame features upper and lower fixed hinges on its side. These hinges connect the door panel to the frame, allowing the panel to rotate around the hinge axis, thereby enabling the opening and closing of the lead door. The lead door consists mainly of the door frame, door panel, hinges, door bolt, clamping mechanism, and buffer stoppers. When power-driven operation is required, an electric or hydraulic impact device can be installed on the wall when the protective door with an adjustable push rod or other driving mechanism is open.

Standardly, buffer blocks are set up, with the inner side of the lead door sealed with a rubber gasket. When closed, they work in conjunction with the door frame to provide sealing and buffering. The structure of the sliding door pull cord is as shown in the diagram. The sliding protective door moves perpendicular to the door opening, i.e., parallel to the wall direction. The walking mechanism is installed above or below the door body. Generally, light-duty door bodies are mounted above the door body, which can be referred to as suspended sliding guide door drive. Heavy-duty door drive mechanisms are installed below the door body, known as bottom-driven sliding guide door.
