Shuttle-Type Passive Control System for Pressure Pipeline Conveying

In this paper, we compare the shuttle type passive control system and the existing technology in detail firstly, what is called passive control is a technology which the passive shuttle control system relies on the energy from the system itself or our natural cycle, such as the gravity flow, the pressure flow, the pressure difference to achieve self-regulation and control without other outside power and active devices. And then we introduce the new shuttle type control units including shuttle type return valve, shuttle-type exhaust and air-adding valve, and the adjustable difference flow pressure safeguard and their applications using several examples, which shows that the shuttle type control series valves are latest best choice for the modern pipeline conveying engineering with simple frame, lost cost and high reliability.
