 Profile: fire control, also known as flame arresters, flame arrester is to prevent external flame fleeing there are flammable or explosive gas equipment, pipelines, or equipment to prevent fire in the pipeline between the spread. Flame arrester is the application of the flame through the small pores heat conductors, due to heat loss and extinguished the principles of design and manufacturing. Flame arrester of the fire retardant layer structure of gravel-type, wire type or corrugated. For combustible gas pipelines, such as gasoline, kerosene, light diesel oil, benzene, toluene, crude oil or oil products storage and filling the flare system, gas purification Tonghua system, gas analysis systems, coal mine gas drainage system, heating fuel gas pipe Internet can also be used in acetylene, oxygen, nitrogen, natural gas pipeline supplies. The valve can be used with the breathing valve package can also be used alone. 
 First, use 
 Fleeing there to prevent external flame flammable gas equipment, pipelines, or equipment to prevent fire in the pipeline between the spread. 
 Second, the care and maintenance 
 ◆ To ensure that the flame arrester performance to achieve the purpose of use, flame arrester is installed, you must carefully read the manufacturer's instructions, and carefully check the signs and the installation requirements are the same pipeline. 
 ◆ flow on the flame arrester must be marked with the same media flow. 
 ◆ should be checked once every six months. Check whether there is blockage fire retardant layer, deformation or corrosion and other defects. 
 ◆ blocked the fire retardant layer should be cleaned to ensure smooth flow of each hole, the deformation or corrosion of the fire retardant layer should be replaced. 
 ◆ Clean flame arrester core components should be high pressure steam, non-corrosive solvents or compressed air purging, the hardware may not use sharp scrub. 
 ◆ reinstall the fire retardant layer, should be updated and confirmed gasket sealing surface is clean and no damage, no leaks.
