Abstract

The invention relates to a fireproof watertight door which is a single vertical hinged door structurally. The fireproof watertight door comprises the specific parts: a door leaf, a hinge, a door frame, an anchor part and a locking mechanism. The door frame is fixed by the anchor part, the door leaf is mounted in the door frame and one end of the door leaf is connected to the door frame through thehinge, the locking mechanism is arranged between the door frame and the door leaf, the door leaf is composed of a sealing strip, two durable steel fireproof anti-explosion plates, a fireproof heat-isolating material, a fireproof expansion strip and a protecting hood, the sealing strip and the fireproof expansion strip are arranged between the door leaf and the door frame, the durable steel fireproof anti-explosion plates and the fireproof heat-isolating material are arranged in the protecting hood, the locking mechanism is mounted between the durable steel fireproof anti-explosion plates andthe position, on the rear sides of the durable steel fireproof anti-explosion plates, of the protecting hood is filled with the fireproof heat-isolating material.

Description

technical field [0001] The invention relates to a fireproof watertight door, which is suitable for nuclear islands and auxiliary workshops of nuclear power plants. Background technique [0002] The fire-proof watertight door is located in the GB corridor of the nuclear island plant. The airtight door added after the Fukushima nuclear power plant accident is mainly to prevent tsunami and seawater backflow; Above-mentioned problem designs a kind of fireproof watertight door and just seems particularly important. Contents of the invention [0003] The fireproof watertight door of the present invention has the following protective functions. When an earthquake occurs in the area where the nuclear power plant is located, it can resist earthquakes and prevent fire; at the same time, when seawater backflow caused by a tsunami occurs, it can prevent seawater from entering the interior of the nuclear island. [0004] In order to solve the above technical problems, the present inve...
