Water-proof Airtight Door Brief Introduction
Water-proof Airtight Door is used for underground drainage pump room to the bottom of the main substation and the main channel, easy to close, in order to prevent the water suddenly immersed. The air-tight door is made up of the flat steel plate,stiffened plates,ring beam and other combinations.The maximum pressure is 98KPa. Doorcase is channel steel, i-steel composite frame structure. Tension device is wedge sliding wedge tight. Hinges with rolling bearing support. Airtight door is a kind of can increase the tightness of the door. Air-tight door wood, steel materials. Key components are sealing device.

Water-proof Airtight Door Notices:
（1）Check the construction site of the gas, the concentration of harmful gases such as carbon dioxide. The construction site must be well ventilated, the concentration of the gas, carbon dioxide gas shall not exceed the "coal mine safety regulations" regulation
（2）Inspection of construction sites around 5m roof, alley gang support, identify problems and timely reporting, processing, no hidden before construction.
（3）Surrounding wall to re-slotting see hardtop, hard coal to help with then real; wall formation without cracks, heavy stitch seams and empty. Undercutting should note the following：
（4）Required fire doors, closed doors and walls through cable lines, to set aside time in the drywall opening position, where the cable passes, to be set up over the line pipe and press the cable hanging neatly spaced.
（5）Fire doors, closed doors wall to use non-flammable building materials, tight without leakage. Brick walls, the pressure stubble to stagger, transverse to the level, arranged neatly.In accordance with the 1:3 ash, sand mortar formulated ratio.
（6）In masonry fire doors, closed doors process, others close to the operator is strictly prohibited to prevent tools, materials falling injured personnel.
