METHOD OF TRANSPORTATION OF HYDRAULIC MIXTURE THROUGH PIPE-LINE Russian patent published in 1994 - IPC

FIELD: pipe-line transport. SUBSTANCE: method involves feeding hydraulic mixture from reservoir to pipe-line by head pumping plant with opened gate valve. In case of necessity to actuate separator-scraper the gate valve is closed and other gate valves are opened. Upon receipt of signal from transducer about passage of separator-scraper opened gate valves are closed and closed gate valve is opened. During movement in linear section of pipe-line a portion of hydraulic mixture enclosed between separator-scrapers is divided into thicker and more viscous part and less viscous part. EFFECT: enhanced reliability. 2 dwg
