Description

Marine single-open fireproof door Technical Field The utility model relates to a marine single-open fireproof door, and belongs to the field of fireproof doors. Background In the safety protection system of ships, prevent fire spreading, guarantee personnel life and property safety's key facility, simultaneously, personnel's activity is frequent in the cabin of ships, equipment operation in-process also can produce heat and waste gas, in order to maintain good air quality, guarantee personnel's health and equipment normal operating, it is crucial that the function of ventilating is possessed to prevent fire door, traditional marine fire door mostly adopts complete seal structure, though can effectively block fire and smog, in daily use, this kind of leakproofness leads to the incasement air to circulate, easily cause the air to turbidity, harmful gas accumulates scheduling problem, greatly influence comfort level and the security of crewman's work and living environment, along with technological development, partly prevent fire door begins to add ventilation structure in order to satisfy ventilation demand, current marine fire door ventilation module is usually offered the air vent on the fire door body, and set up sealed lid in the air vent both sides, sealed lid is generally through simple articulated or buckle structure links to each other with preventing fire door body, at daily use, sealed lid opens, utilize natural ventilation or built-in fan to realize the air circulation, in order to maintain the air quality in the cabin.
