The invention relates to a novel tank type fuel transporting and refueling truck. The novel tank type fuel transporting and refueling truck mainly comprises a vehicle chassis system, a fuel pumping transmission system, a fuel tank system, fuel loading and unloading pipelines, an external 380-volt power supply pump assembly, a control system and a security protection system. The right of the truck body is provided with a control cabinet, and a DN65 (nominal diameter) three-way ball valve, a three-way screen, DN65 straight-through ball valves, a bottom valve air control switch, a CRJ rapid joint anode strip plugging cover, a pipeline pressure meter and a vacuum meter are arranged inside the control cabinet, so that the functions of bottom fuel loading during fuel loading of the truck and automatic-flow fuel unloading, pump discharging and refueling; the left of the truck body is provided with an operating cabinet which is provided with two Censtar refuelers, DN25 straight-through ball valves, a 10-meter one-inch refueling rubber hose refueling gun and the like. The novel tank type fuel transporting and refueling truck replaces a traditional fuel loading manner with the bottom fuel loading manner and performs totally-closed loading, thereby having significant influence on environmental protection and human health ensurance; subsea valves can achieve bottom fuel loading and unloading, so that safety, environmental protection, high efficiency and operative convenience can be obtained.
