The invention provides an integrated oil filling pipe flaring structure which comprises an oil filling port, an integrated flaring structure and an oil filling circulating pipe. The oil filling port is assembled at the upper part of the integrated flaring structure and is welded with the integrated flaring structure, the oil filling circulating pipe is positioned on the outer side of the integrated flaring structure, one end of the oil filling circulating pipe is communicated with the integrated flaring structure and is welded with the integrated flaring structure, and the other end of the oilfilling circulating pipe is communicated with a carbon tank; the integrated flaring structure is formed by machining a main pipe straight pipe through a flaring technology, and the eccentricity of the integrated flaring structure is 0 to 5 mm. The integrated oil filling pipe flaring structure is reasonable in structural design, an oil pipe flaring is omitted, the welding process of the oil pipe flaring and the main pipe is omitted, the risk of welding leakage is eliminated, the risks that due to welding slag existing at the welding position, oil filling smoothness is reduced, and the corrosion resistance of the welding position is poor are eliminated, meanwhile, the process is simplified, the production efficiency is greatly improved, and the cost is reduced.

    一种一体式加油管扩口结构,包括加油口、一体式扩口结构、加油循环管;所述加油口装配在所述一体式扩口结构上部并且与一体式扩口结构焊接,所述加油循环管位于一体式扩口结构外侧,所述加油循环管的一端与一体式扩口结构连通并且与一体式扩口结构焊接,所述加油循环管的另一端与碳罐连通;所述一体式扩口结构是将主管直管通过扩口工艺加工而成,所述一体式扩口结构的偏心量为0‑5mm。本发明所述的一体式加油管扩口结构,结构设计合理,取消了油管扩口,取消了油管扩口与主管的焊接工艺,消除了焊接泄露的风险、焊接处存在的焊渣导致加油顺畅性能下降、焊接处耐腐蚀性能较差的风险,同时简化了工艺,大大提高了生产效率,降低成本。
