抽屉式 波纹 阻火器 概述： I. Overview of drawer type corrugated flame arrester :
是用于安装原油、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，通常与呼吸阀配套使用，其主要功能是允许易燃易爆的气体通过，对外界传入储罐的火焰起有阻止与窒息作用。 Drawer type corrugated flame arrester is also called ZGB-II type drawer flame arrester. It is used to install crude oil, gasoline, kerosene, diesel, aromatics, sulfur and other oils or other chemical materials on fixed top storage tanks. For supporting use, its main function is to allow flammable and explosive gases to pass through, and to prevent and suffocate the flame introduced into the storage tank from the outside. The flame arrester can be used with the ventilation pipe or used alone. Other specifications can be provided according to user requirements. 28 ℃ 的甲类、油品、氢氧液化类和闪点低于 60 ℃ 的煤油、柴油、甲笨、原油等，可与呼吸阀配套使用，又可单独使用，内浮顶油罐通气管上，加油站地下油罐通气管上。 The flame arrester is suitable for pipelines, Class A, oil products, hydrogen liquefaction products with a flash point below 28 ℃ , and kerosene, diesel, methylbenzene, crude oil with a flash point below 60 ℃ . It can be used with breathing valves. It can be used alone, on the inner floating roof oil tank vent pipe, on the gas station underground oil tank vent pipe.
抽屉式 波纹 阻火器工作原理： Working principle of drawer type corrugated flame arrester:
Most flame arresters are composed of many small, uniform or non-uniform channels or pores of solid materials that can pass through the gas. These channels or pores are required to be as small as possible, as long as they can pass the flame. In this way, after the flame enters the flame arrester, it is divided into many small flame streams and is extinguished. The mechanism by which the flame can be extinguished is wall effect and heat transfer.

抽屉式阻火器维修保养： V. Maintenance of drawer flame arrester:
In order to ensure that the performance of the flame arrester reaches the purpose of safe use, the flame arrester should be regularly inspected and maintained.
、 阻火器每半年检查一次，检查阻火层芯子是否堵塞，变形，腐蚀等。 1. Check the fire arrester every six months to check whether the core of the fire retardation layer is blocked, deformed, corroded, etc.
、 发现被堵塞的阻火层芯子应清洗干净，确保芯子上的每个孔眼畅通，对于变形和腐蚀的阻火层应更换。 2. The core of the fire blocking layer found to be blocked should be cleaned to ensure that each eyelet on the core is unblocked, and the fire blocking layer that is deformed and corroded should be replaced.
、 重新安装阻火层芯子时，应保证结合面严密不得漏气。 3. When reinstalling the core of the fire barrier layer, it shall be ensured that the joint surface is tight and free of air leakage.
