Integrated uncapped fueling pipe

The invention relates to an integrated uncapped fueling pipe which can directly fill fuel without screwing off a fueling cap of a motor vehicle. The pipe is characterized in that the fuel oil gun canbe directly lifted to refuel without unscrewing the fuel oil cap, and the fuel oil vapor emission control standard of the sixth national standard GB18352 issued by the ministry of ecology and environment is met, thereby avoiding the pollution of the fuel oil vapor emission and the flammable and explosive accidents; as well as by adopting that standardized design of the multi-cut plug connection, the technology and the structure are simplified, the product quality is more stable and reliable, and the production cost is reduced. 种能够满足机动车不需拧开加油盖直接加注燃油的体式无盖加油管。其特征是具有不需拧开加油盖直接提枪加注燃油，满足国家生态环境部颁发的GB18352国六标准关于加油过程中燃油蒸汽排放的控制标准，避免燃油蒸汽排放污染和易燃易爆事故；以及采用多截插接标准化设计，使工艺、结构简单化，产品质量更加稳定可靠，降低生产成本。
