是加油站，小型油罐透气不可少配套设备，是原设计的更新换代产品。 Fire blocking vent cap is a gas station, small oil tank ventilation essential supporting equipment, is a replacement product of the original design. 纹管道阻火器 连接形式有法兰连接何螺纹连接两种。 There are two types of corrugated pipe flame arrester connection: flange connection and thread connection. The top cap of the fire-resistant breathable cap is spray-coated on the surface of the refractory steel plate.
The shell is made of cast aluminum, and there are two types of stainless steel corrugated plate and aluminum corrugated plate, which meet the technical requirements of GB-5908-86. When the oil tank material swells or enters the oil, it is vented out through the flame-resistant corrugated plate, and when the oil is discharged from the oil tank, it sucks into the tank and
Stop all fire sources from passing through to ensure safety. The vent cap should be installed vertically on the top of the tank. The breathability of the corrugated board of the breathable cap should be checked frequently to ensure good fire resistance and breathability. Unscrew the cap on the vent cap during maintenance and loosen it.
Open the screw that fixes the fire wick, remove the fire wick, and check whether the fire wick is blocked, deformed or rusted. Should be cleaned or replaced in time, check twice a month.
Second, the use of RFZT-1 fire resistance breathable cap
RFZT-1 fire-proof breathable cap is an important accessory for urban industrial and mining enterprises, gas stations, and installed in storage tanks (or small oil tanks for light oil products with a pump capacity of 25m2 / n or less).
