Double-channel anti-blocking asphalt conveying pipeline structure

Abstract

The utility model belongs to bitumen delivery technical field, specifically disclose a double -channel anti -blocking bitumen delivery pipeline structure, including first connecting pipe, its two ends are connected with first elbow and second elbow respectively in front and back, the front end of first elbow is connected with feed pipe, the rear end of second elbow is connected with discharge pipe, be connected with first bypass pipeline between feed pipe and first connecting pipe, be connected with second bypass pipeline between first connecting pipe and discharge pipe, first bypass pipeline sets up in the upside of first connecting pipe, second bypass pipeline sets up in the downside of first connecting pipe, install first valve body on first bypass pipeline, install second valve body on second bypass pipeline, the first elbow is covered with first heat preservation layer, the second elbow is covered with second heat preservation layer, can realize main road and bypass dynamic switching, main channel bitumen bonding, can switch to bypass maintenance delivery continuity fast, dispersive material flow pressure, avoid single channel because of partial flow rate too low and cause the risk of jam.
