Description

technical field

[0001] The invention relates to an automatic valve for vehicle-mounted equipment, in particular to an automatic asphalt combined valve device for vehicle-mounted equipment. Background technique

[0002] The use of automatic control valves is an indispensable part in terms of efficiency and energy saving in existing technologies. Manual valves commonly used in traditional industries are inferior to automatic valves in terms of installation cost and efficiency. Especially in the road construction machinery industry, because it uses a large amount of high-viscosity oil such as asphalt, it can be transported after the viscosity is reduced by heating, and the residual asphalt after stopping work will bond the valve core and valve body at room temperature , resulting in manual opening of the valve, which is very laborious; in addition, the temperature of asphalt is close to 200°C when it is working, and the structure and temperature resistance of the manual valve a...
