Radiation protection door, also known as radiation protection door, lead door, lead plate door and radiation protection door, is used to block the entrance and exit of radiation, mainly used in hospital CT room, X-ray room, operating room, DR room, industrial flaw detection room, mining area and so on.
Radiation protection doors can be divided into horizontal doors, sliding doors and electric doors according to door types.
1. horizontal lead door: it can be divided into inner door and outer door, and the structure and material of the door body shall be subject to radiation.
The power (KV) of the wire rod machine and the size of the door opening. Because of the large proportion of manual horizontal doors, the hinge installation is easy to deform, and the manual single door adopts ejector pin door hinge.
2. Push-pull lead door: There are two transmission modes: electric and manual. The electric opening direction is parallel to the wall. The structure and material of the door body are determined according to the power (KV) of the radiator and the size of the door opening. The door frame structure is different from the flat structure.
3. Electric lead door: Electric radiation protection door is generally suitable for larger doors. Because of its heavy weight and difficulty in manual opening, it adopts electric opening mode, which can be divided into flat opening type and translation type.
The installation conditions of the electric lead door are customized according to the power (KV) of the radiator and the size of the door body, the actual radiation dose level of the user and the size of the door opening. Matching of electrical radiation protection doors: safety devices such as door-machine interlock, work indicator light and ionizing radiation sign.
The interior of the radiation-proof door body is welded by rigid polyurethane integral high-pressure foaming process and radiation-proof lead plate, which is a high-strength aluminum alloy frame. After the automatic lifting hydraulic equipment is pressed on the big platform, the special equipment ensures the good flatness of the door leaf, and the whole engineering system has high technology content.
The operating system of electric lead door adopts microcomputer intelligent module, including (frequency converter, infrared protection device, door-machine interlocking device, remote control device, imported motor anti-theft device) and so on. The surface can be decorated with large flat matte stainless steel plates, plastic-sprayed steel plates, aluminum plates, electrolytic plates and other plates according to user requirements.
