The invention discloses a rotary faucet of an under-pressure operation
machine. The rotary faucet comprises a fixed shell, a rotary shaft is arranged in the fixed shell, an adjusting
gasket is arranged on one side in the fixed shell, the rotary shaft is movably sleeved with the adjusting
gasket, and a rotary sealing piece is fixedly mounted on the rotary shaft and located on one side of the adjusting
gasket. According to the rotary faucet, by arranging the adjusting gasket, the rotary sealing piece, a pressing ring, a sealing seat, a first O-shaped ring, a second O-shaped ring, a bearing and an elastic sealing ring, after the rotating shaft is inserted into the fixed shell, the adjusting gasket, the rotary sealing piece, the pressing ring, the sealing seat and the rotating shaft are all in
close contact with one another, so that when the under-pressure operation
machine carries out
liquid circulation operation and sand washing operation, a water hose is lifted by a
winch, a pump
truck pumps liquid to the well bottom through the water hose, the water hose can be kept immovable, the faucet can rotate along with an oil
