Problems solved by technology
[0003] Viscous oil is a heavy petroleum product, which is usually transported by tank truck. The air environment in most areas of our country is extremely cold. During the transportation of viscous oil, the unloading valve is easily frozen. The traditional thawing method It is to directly heat the unloading valve. This heating method is easy to damage the rubber structure inside the unloading valve. On the other hand, the viscous oil has a certain viscosity. Dust-proof treatment, a large amount of dust will be attached after a period of time, and these dusts will have a certain impact on the quality of viscous oil

The invention discloses a viscous oil tank truck discharging valve. The viscous oil tank truck discharging valve comprises a discharging valve body, a dustproof slice and a ball valve element. One side of the bottom of the discharging valve body is rotationally connected with the dustproof slice through a rotating cylinder, one side of the discharging valve body is provided with a rotary rod, andthe center position of the ball valve element is provided with an oil hole. One side of the oil hole is evenly provided with steam outlet holes, the steam outlet holes and steam inlet holes are all located in the ball valve element, and the steam inlet holes communicate with a steam inlet. According to the viscous oil tank truck discharging valve, by injecting steam into the steam inlet, under theflow guiding action of the steam inlet holes and the steam outlet holes, heat source steam enters the ball valve element, the interior of the ball valve core is heated evenly, and therefore the internal structure of the discharging valve is rapidly unfrozen; and meanwhile, due to the fact that the heat released by the steam which is liquefied in the discharging valve is far smaller than leakage prevention rubber structures inside the discharging valve, damage of the internal structures is avoided while unfreezing is carried out, and the service life of the discharging valve is prolonged.
Description
technical field [0001] The invention relates to the technical field of an oil tanker unloading valve, in particular to a viscous oil tanker unloading valve. Background technique [0002] Viscous oil generally refers to heavy petroleum products such as boiler fuel oil and lubricating oil. It has high viscosity at low temperature. It must be heated when sending, receiving and filling to reduce the resistance loss of pipeline transportation and speed up loading and unloading. There is a heating device on the tank truck, and a special heating boiler is installed in the base oil depot, so the requirements for the container (tank truck), sending and receiving oil equipment and pipelines in storage, transportation, and sending and receiving are different from those for light oil. [0003] Viscous oil is a heavy petroleum product, which is usually transported by tank truck. The air environment in most areas of our country is extremely cold. During the transportation of viscous oil, ...
