进口砾石阻火器产品描述：
美国《LAINE》莱恩--进口砾石阻火器”砾石阻火器（又名防火器），阻火器的作用是防止外部火焰窜入存有易燃易爆气体的设备、管道内或阻止火焰在设备、管道间蔓延。用于安装原油、汽油、煤油、柴油、芳烃、硫等各类油品或其它化工物料的固定顶式储罐上,通常与机械呼吸阀配套使用,其主要功能是允许易燃爆气体通过、对外界传入储罐的火焰起有阻止窒息的作用。管道阻火器可以在高寒地区低温条件下使用的特点，它可以与通气管配套或单独使用。
American Laine Lane imported gravel flame arrester gravel flame arrester (also known as fire extinguisher), the role of flame arrester is to prevent the external flame from escaping into the equipment and pipeline containing flammable and explosive gases or prevent the flame from spreading between the equipment and pipeline. It is used for the installation of fixed roof tanks for crude oil, gasoline, kerosene, diesel oil, aromatics, sulfur and other oil products or other chemical materials. It is usually used together with mechanical breathing valve. Its main function is to allow flammable and explosive gases to pass through and prevent smothering the flame from the outside. The pipeline flame arrester can be used under the condition of low temperature in high and cold areas. It can be used with ventilation pipe or alone.
