Shop name:Chong Qing Shuo Yue Ke Ji You Xian Gong Si Application: -, , petrol below 90#.The slim shape of the - transfer and the balanced weight of the transfer body make the operation easy and labor-saving.With high strength, light weight, wear resistance, corrosion resistance and sealing properties.The transfer is equipped with a color plastic sheath, comfortable. The -sealing transfer has the function of automatically shutting the transfer after the oil fills the container, which is a modernization support for the metering tanker. It is especially suitable for unmanned gas stations, which can prevent oil or foam from overflowing, keep the station clean, and reduce pollution. Working principle:The nozzle is equipped with a thin vacuum tube. When the pressure lever is in the "on" position, the liquid flowing from the transfer sucks through the small hole in the nozzle into the vacuum tube. As long as passes through the vacuum tube, the liquid will continue to , when the tank When the liquid level rises to cover the height of the hole in the nozzle, the stops flowing and the transfer closing device automatically starts. Designed for factories, gas station and househood Auto-off when the oil is fulfilled,Easy to clean, install and maintain. Install the connector: (1)If the transfer inlet is a NPT ()tapered thread, with a suitable sealant. (2)If the transfer inlet is BSPT (British standard)straight thread,it must be sealed with a rubber O-ring. (3) the connector to the inlet of the transfer with care.Do not overtighten the threads to prevent the transfer body from cracking. Operation: (1)The transfer switch shall be set with 3 fixed gears,which can be refueled according to the size. (2)During the refuelingprocess,when the oil or foam submerges the hole at the lower end of the barrel,the transfer will automatically .If spray or foam causes the transfer to ,the foam can disappear and fire-again. (3)When using the to control the refueling,the non-slip on the barrel can be used to -refuel in the tank,without the need for hand-holding,the oil is fully -closing. Maintenance: (1)The vent hole at the lower end of the barrel should be kept clear and blocked by foreign matter. (2)After the transfer is used to up,avoid collision. (3)Do not need lubrication and durability.
