The invention relates to a plastic fuel tank internal-external exhaust system and a connecting method. The exhaust system comprises a fuel tank shell, internal exhaust pipes and exhaust joints, the oil tank shell is at least provided with an oil pump hole and an oil tank exhaust hole. One end of the internal exhaust pipe is clamped and matched with the exhaust connector, and the exhaust connectorpenetrates through the oil tank exhaust hole and then is welded and matched with the oil tank shell. The internal and external exhaust system of the plastic fuel tank is simple in preparation process,only one exhaust joint is used, the use of a quick connector is reduced, the welding times of a welding process are reduced, and the production cost is reduced.
本发明涉及一种塑料燃油箱内外排气系统及连接方法,包括油箱壳体、内部排气管及排气接头;在油箱壳体上至少设置有油泵孔和油箱排气孔;内部排气管的一端与排气接头卡接配合,排气接头穿过油箱排气孔后与油箱壳体焊接配合。本发明的塑料燃油箱内外排气系统制备工艺简单,并且仅使用一个排气接头,减少了快插接头的使用及减少了焊接工序的焊接次数,降低了生产成本。
