The conventional configuration of the previous oil tank truck is a special oil pump, equipped with pump inlet and pump outlet pipes. These pipes include Wuhan carbon steel and 304 stainless steel, refueling tanks or oil transportation tanks. These tanks are generally from 5 m³ to 30 m³, and some oil tank semi trailers have a volume of 55 m³. In the past, the main oil inlet mode of the tank truck was to fill the tank from the manhole above the tank. However, now, in order to improve safety, the tank truck production of QUEST VEHICLE has done the bottom filling process, that is, the so-called oil filling process under the European standard.
What is bottom canning? Bottom Canning is also known as lower oil loading system, which is an important part for lower oil loading Transformation: the main components of bottom canning include tail gas recovery system, anti overflow system, submarine valve, European standard tank mouth, probe, SO2 socket, anti-static system, bottom canning API connector, etc. Our main production process is: steam purging, washing and wiping the tank body; Cut oil sump and install Subsea valve; Install oil circuit system; Install gas phase circuit; Replace the closed manhole cover (European standard manhole cover); Water pressure, air tightness and kerosene leakage test.
This is the overall working picture of the lower oil loading system, from which we can see the importance of electrostatic grounding strip. The electrostatic grounding device of large gas stations is mainly fixed. This is generally solved by gas stations. They install one near the large main oil depot. When each gas truck comes to refuel, it can be quickly connected. The electrostatic grounding alarm is a standardized anti-static product for oil loading and unloading, It can not only lead the static electricity generated in the process of liquid transfer to the earth, but also automatically detect the grounding condition in the whole process. Sound alarm in case of poor grounding or disconnection to ensure the safety of production and operation.
It can be easily seen from this picture that the oil tank truck can be divided into silos. Each silo needs an aluminum alloy tank mouth (also known as manhole), which can be equipped with anti leakage probe, submarine valve, oil unloading joint (lower oil valve), oil vapor recovery valve and submarine valve, also known as emergency shut-off valve. It is installed at the bottom of the tank. It is easy to operate and time-saving Safety and environmental protection.
Pressure balanced submarine valve is used for multi bin oil tank truck, which can be loaded and unloaded separately in different oil silos. The tee design simplifies the pipeline, reduces the load, is simple to operate, safe and reliable.
The pneumatic cut-off valve is installed at the bottom of the tank body of the oil tank truck and can be used for lower loading and refueling. The internal pressure of the valve is small and the flow is large. There is a cut-off groove at the flange of the valve body. In case of an accident in the oil tank, because the cut-off groove is unable to bear excessive impulse, the vehicle body pipeline and the tank will be automatically disconnected, and the automatic centering plunger and durable spring will remain sealed, and the medium in the tank will not leak, So as to ensure the safety of the oil tank. When there is no air source or it cannot be opened for other reasons, the cylinder piston rod can be folded and opened manually.
The figure above shows the aluminum alloy European standard tank mouth, also known as manhole cover, which is installed on the top of the oil tank with built-in breather valve and emergency exhaust function. Oil and gas recovery valve, oil measuring hole, anti overflow probe rod, etc. can be installed on the manhole cover. During oil loading, when the liquid level reaches the detection position, the sensing system will automatically alarm to stop oil loading. The built-in breather valve keeps the internal pressure of the oil tank stable and balanced with the external pressure during oil transportation. Its dumping and overflow prevention design keeps the oil tank truck sealed in case of accident. The emergency exhaust device will automatically open to release the pressure in the tank when the pressure in the tank rises sharply, so as to prevent accidents and greatly improve the safety of oil transportation.
