At present, the oil port of a railway oil tank truck is designed in an open mode, and a constructor can insert a loading and unloading oil pipe into the oil port so as to load and unload oil through the loading and unloading oil pipe. However, the inner diameter of the oil port is usually much larger than the outer diameter of the loading and unloading oil pipe, so that during the loading and unloading of oil products, oil vapor formed by heating the oil products in the railway tank wagon can diffuse outwards along the gap between the loading and unloading oil pipe and the edge of the oil port, and unnecessary loss of the oil products is generated. The lost oil product not only causes environmental pollution, but also increases the possibility of fire and explosion accidents. Therefore, it is required to seal the oil port of the railway tank car to prevent the diffusion of the oil vapor in the railway tank car.
In the process of loading and unloading oil products of the railway tank wagon, the oil port is mainly sealed by using an asbestos quilt. Specifically, an asbestos quilt capable of completely covering the oil port can be selected, a through hole with the same size as that of the loading and unloading oil pipe is drawn in the asbestos quilt, the asbestos quilt is firstly covered on the oil port in the process of loading and unloading oil, and then the loading and unloading oil pipe penetrates through the through hole in the asbestos quilt to penetrate into the tank body of the railway oil tank truck so as to carry out the operation of loading and unloading oil.
Asbestos is easily contaminated and damaged by oil products and therefore requires frequent replacement, increasing the cost of the seal.
