2. also comprise the sealing plate that is fixed on body of wall door opening edge and contacts with door leaf.
3. be provided with seal in the slit between said wicket and each door leaf.Said seal is processed by neoprene or ethylene propylene diene rubber.
4. be provided with hairbrush between the medial surface of said base and door leaf.
5. said dolly has the roller that rolls and contact with guide rail.
6. said guide rail end is provided with stopper, and is excessively mobile in order to prevent dolly.
7. said door leaf is formed through securing member is fastening by three-ply metal at least; The width of adjacent metal sheets splicing seams is more than or equal to 150mm.
8. said guide rail top is provided with along the extension of rail length direction and is fixed on the cover plate on the body of wall.
The utility model structure design is simple, and is easily manufactured, opens and closes smooth and easy; Nuclear plant safety effect and instructions for use have effectively been satisfied; Reach caryoplasm and protect QA1 level nuclear safety class requirement, and knot procurement cycle is short, economic benefit is obvious, can be widely used in China's nuclear power station special door construction field.
