Pneumatic type closed smoke-blocking type safety fireproof door

Abstract

The invention discloses a pneumatic type closed smoke-blocking type safety fireproof door, and belongs to the technical field of fireproof doors. According to the pneumatic type closed smoke-blocking type safety fireproof door, when a fire disaster occurs, a ball pricking steel needle can spontaneously prick a material storage balloon, a pneumatic solution flows out, pneumatic powder reacts to generate a large amount of carbon dioxide, the generated carbon dioxide flows into an arc-shaped guide cylinder through a communicating hole and can push the push rod piston, and therefore the fireproof door in an open state is closed, the fireproof door is ensured to be in a closed state when the fire disaster happens, then smoke is prevented from penetrating through the fireproof door and rushing to an escape channel, the safety performance is greatly improved, through the arrangement of an air leakage door opening assembly, escape personnel can make an air leakage main pipe communicated through a first valve and a second valve on the two sides of the fireproof door correspondingly, and therefore the carbon dioxide is sprayed out; and the sprayed carbon dioxide can achieve a flame-retardant effect, so that fire spreading is hindered to a certain extent, and more sufficient escape time is won for people.

Description

technical field [0001] The invention relates to the technical field of fire doors, and more specifically, relates to a pneumatic sure-closing and smoke-blocking safety fire door. Background technique [0002] Fireproof materials refer to various materials that play an absolute role in modern fire prevention and are mostly used in buildings. Commonly used fireproof materials include fireproof boards, fireproof doors, fireproof glass, fireproof paint and fireproof bags, etc. Among them, fire doors refer to doors that can meet the requirements of fire resistance stability, integrity and heat insulation within a certain period of time. [0003] In addition to the function of ordinary doors, fire doors can also prevent the spread of fire within a certain period of time and ensure the evacuation of personnel. When a fire occurs, not only the high temperature of the fire but also the smoke emitted by burning objects threaten people's lives. According to statistics, more than 80% ...

AI Technical Summary

Problems solved by technology

[0004] In theory, the fire door needs to be kept closed, but in actual use, due to various human factors, people often open the fire door but forget to close it, resulting in the fire door being open. When a fire breaks out, due to fire The door is open, causing the smoke to flow through the fire door to the escape channel, thus affecting people's escape, and the safety performance is low
