Problems solved by technology

[0002] The use of automatic control valves is an indispensable part in terms of efficiency and energy saving in existing technologies. The 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 are relatively high. To ensure a certain working temperature and a certain service life, the manual valve must meet These requirements, the manufacturing cost is very high

In the existing technical field of the road construction industry, especially in the vehicle equipment, there are already some pneumatic two-way and three-way valves with practical capabilities, which have solved the problem of inconvenient operation functionally, but their application range is only limited to Some generally simple connections, through the connection of pipes and valves, realize some simple working cycles, but they are only independent in overall design, so the use of space in vehicle equipment is greatly limited.
