  1防火门的概念及作用

  The concept and function of fire doors

01

  防火门通常是指设在楼梯走道、电梯间、电缆井、排烟道等等一些封闭场所的门。

  Fire doors usually refer to doors installed in enclosed places such as stairwells, elevator shafts, cable shafts, smoke exhaust ducts, etc.

  防火门起的作用就是在一定时间内能满足耐火稳定性、隔热性,可以阻止火势蔓延及扩散,确保人员疏散是消防工作中必不可少的设备。

  The function of fire doors is to meet the requirements of fire resistance stability and thermal insulation within a certain period of time, which can prevent the spread and expansion of fire, and ensure that personnel evacuation is an essential equipment in firefighting work.

  2防火门图解构成

  2 Diagram Composition of Fire Doors

  防火门是由门框、面板(内填充隔热材料)、防火五金配件、电磁门吸等部件组成。门扇通过合页连接形成,门上配置闭门器、防火锁,双扇门还加装暗插销(装在固定扇一侧)和顺位器,以防门扇中缝的搭叠。与常开防火门联动的有火灾探测器和火灾联动控制系统。

  A fireproof door is composed of door frame, panel (filled with insulation material), fireproof hardware accessories, electromagnetic door stopper and other components. The door panels are connected by hinges, and are equipped with door closers and fire locks. Double doors are also equipped with concealed locking pins (installed on one side of the fixed panel) and alignment devices to prevent overlapping of the seams in the door panels. Fire detectors and fire linkage control systems are linked to normally open fire doors.

  1、防火材料

  1. Fireproof materials

  防火门门扇内填充对人体无害的防火隔热材料.

  The fireproof door leaf is filled with non-toxic and harmless fireproof insulation materials for the human body

  市场上填充物大致有无机防火芯板,珍珠岩,磷镁芯板,硫化镁等。?

  The fillers on the market generally include inorganic fireproof core board, perlite, magnesium phosphate core board, magnesium sulfide, etc.?

  珍珠岩防火门芯板采用膨胀珍珠岩为主要原料,与一定比例的无机高黏合剂和化学添加剂混合,经过一整套工序加工而成。由于采用的膨胀珍珠岩是天然珍珠岩矿砂,经1300℃以上高温瞬间膨胀而成的、结构呈中空蜂窝状的颗粒球形体,因此制成的防火门芯板是一种天然绿色的理想产品。

  The perlite fireproof door core board is mainly made of expanded perlite, mixed with a certain proportion of inorganic high adhesive and chemical additives, and processed through a complete set of procedures. Due to the fact that the expanded perlite used is natural perlite mineral sand, which expands instantly at high temperatures above 1300 ℃ and has a hollow honeycomb shaped particle spherical structure, the fireproof door core board made of it is an ideal natural, green and environmentally friendly product.

  2、顺序器(顺位器)

  2. Sequencer

  双扇防火门应具有按顺序自行关闭的功能,配合闭门器使用,控制双开门先后关门顺序。

  Double leaf fire doors should have the function of self closing in sequence, and be used in conjunction with door closers to control the closing sequence of the double doors.

  防火门无法确保双扇防火门能正确按顺序关闭 ,容易产生门隙问题,无法达到有效隔阻烟火的设计要求,让门按左右顺序关上,如果右边那扇先关上,顺位器顺序器就会顶住,让左边那扇防火门压下顺位器顺序器并先关上门,右边防火门再按顺序关上。

  Fire doors cannot ensure that double leaf fire doors can be closed correctly in sequence, which can easily lead to door gaps and fail to meet the design requirements for effective smoke and fire isolation. It is recommended to close the doors in left and right order. If the right leaf is closed first, the sequencer will press down on the left leaf fire door and close the door first, and then close the right leaf fire door in sequence.

  双扇防火门通过安装顺位器顺序器,保证左边防火门能先行关闭,右边防火门随后关闭,双扇防火门才能确实有效隔阻烟火。

  Double leaf fire doors can only effectively block smoke and fire by installing a sequencer to ensure that the left fire door closes first and the right fire door closes later.

  3、闭门器

  3. Door closers

  防火门应安装防火门闭门器,或设置让常开防火门在火灾发生时能自动关闭门扇的闭门装置(特殊部位使用除外,如管道井门等)。防火门闭门器应经认可授权检测机构检验合格;自动关闭门扇的闭门装置,应经认可授权检测机构检验合格。

  Fire doors should be equipped with fire door closers or door closing devices that allow normally open fire doors to automatically close the door leaf in the event of a fire (except for special parts such as pipe well doors). Fire door closers should be inspected and qualified by nationally recognized and authorized testing institutions; The door closing device that automatically closes the door leaf should be inspected and qualified by a nationally recognized and authorized testing institution.

  普通闭门器:分为定位闭门器跟不定位闭门器。

  Ordinary door closer: divided into positioning door closer and non positioning door closer.

  定位闭门器,门扇开启到90°可以停门,需要手拉一下才能关回来。(一般均为常开门用)

  Position the door closer, open the door leaf to 90 ° to stop the door, and you need to pull it by hand to close it back. (Usually used for opening doors frequently)

  不定位闭门器,门扇无论开启到什么角度,门都会自动关回来。不定位闭门器可以开到120°~180°。(一般均为常闭门用)

  Without positioning the door closer, the door will automatically close back no matter what angle the door leaf is opened. The non positioning door closer can be opened to 120 °~180 °. (Usually used for closed doors)
