Description

Technical Field

[0001] The utility model relates to the technical field of liquid transport vehicles, in particular to a liquid transport vehicle with a pressurized liquid unloading function. Background Art

[0002] Liquid transport tankers are specially used to transport various liquid items, such as fuel, chemical products, food liquids, etc. Compared with traditional container transportation, liquid transport tankers do not have any risk of leakage and can efficiently and quickly transport liquid goods from loading and unloading points to the destination. Liquid transport tankers are made of high-strength steel, and the internal coating meets the standard requirements. The tank body has excellent corrosion resistance and will not corrode or contaminate the liquid due to long-term contact with the liquid. At the same time, liquid transport tankers are also equipped with stable suspension systems, braking systems, anti-rollover devices and other safety equipment to ensure the safe transportation of goods. Liquid transport tankers are an efficient, safe, and economical way to transport liquid goods. With the growing demand for liquid goods in recent years, the application scope of liquid transport tankers has become more and more extensive, and it is expected to become one of the mainstream methods in the transportation industry in the future.

[0003] Liquid transport tank trucks have built-in liquid unloading function. Generally, liquid transport trucks use external pumps or self-boosting devices. The external pump structure is generally set in the rear operating box, which requires a large operating box to place the external pump. The interior of the operating box is divided into three major parts, including: liquid phase pipeline, gas phase pipeline, boosting pipeline, etc. Each pipeline is installed with a valve. When discharging the liquid, the booster device and the external pump need to cooperate with each other and open or close the corresponding valves of the liquid phase pipeline, gas phase pipeline and boosting pipeline in turn to discharge the liquid inside the liquid transport tank truck, and always observe the pressure gauge to stably control the pressure changes inside the liquid transport tank truck, thereby completing the liquid discharge work.

[0004] However, this method of drainage is complicated and requires cumbersome steps. It requires professional training or experienced operators to perform the drainage work. It is difficult for untrained people to operate and the work efficiency is slow. Because there are many valves to be operated, the operation time is increased and the drainage speed is reduced. Therefore, a new solution is needed to solve this problem. Utility Model Content
