Steel heat-insulation fireproof door leaf
The invention discloses a steel heat-insulation fireproof door leaf. The steel heat-insulation fireproof door leaf comprises a door leaf body, wherein the door leaf body comprises a frame and a steelskin, and a filling cavity is formed between the frame and the steel skin; a steam generation mechanism comprises a water storage tank, heat conduction fins are arranged outside the water storage tank, the heat conduction fins are connected with the water storage tank and the metal skin, the water storage tank is connected with an air guide pipe, and an air guide one-way valve is arranged on the air guide pipe; a pressurizing spraying mechanism comprises a pressurizing cylinder; a piston body is connected in the pressurizing cylinder in a sealing and sliding mode; the piston body divides the pressurizing cylinder into an upper cavity and a lower cavity, the upper cavity communicates with the air guide pipe; the lower cavity is filled with fire extinguishing liquid; the lower cavity is connected with a high-pressure hose; a pressure release valve is arranged on the high-pressure hose; the high-pressure hose is connected with a front flow dividing pipe and a rear flow dividing pipe; andthe front flow dividing pipe and the rear flow dividing pipe are connected with a water mist spray head correspondingly. According to the arrangement, when a fire source approaches the door leaf, corresponding fire extinguishing operation can be automatically carried out, the temperature around the door leaf is reduced, and therefore good heat insulation and fireproof effects are achieved.
本发明公开了一种钢质隔热防火门扇，包括门扇，门扇包括框架和钢制蒙皮，框架和钢制蒙皮间形成填充腔；蒸汽生成机构包括储水箱，储水箱外设置导热肋片，导热肋片与储水箱和金属蒙皮连接，储水箱连接导气管，导气管上设置导气单向阀；增压喷淋机构包括增压筒，增压筒内密封滑移连接有活塞体，活塞体将增压筒分割成上空腔和下空腔，上空腔与导气管连通，下空腔内填充有灭火液体，下空腔连接高压软管，高压软管上设置有泄压阀，高压软管连接有前分流管和后分流管，前分流管和后分流管分别与细水雾喷头连接。通过上述设置，能够在火源逼近门扇时，自动进行相应的灭火操作，降低门扇周围的温度，从而具有良好的隔热和防火效果。
