Abstract
This utility model belongs to the field of valve technology and relates to a rapid cleaning and unloading valve for asphalt tank trucks to prevent solidification. It includes a valve body with a hollow groove in the middle. The hollow groove is connected to a heating component via a steam delivery pipe. Multiple sets of vent holes adapted to the heating component are located on the top of the valve body. The heating component is a miniature electric steam generator. This utility model can heat the asphalt unloading valve body, thereby slowing down the cooling rate of the asphalt during unloading and preventing it from solidifying due to temperature drop, which could cause blockage and affect unloading efficiency. Simultaneously, a servo motor can drive the movement of the hollow disc and rubber ring, allowing distilled water adhering to the inner wall of the asphalt unloading valve body to detach, thus reducing the long-term adhesion of distilled water to the inner wall and the potential for scale formation.
