Rotary faucet of under-pressure operation machine

Abstract

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 pipe, and the actual site requirement is met.

Description

technical field [0001] The invention belongs to the technical field of petroleum exploitation, and in particular relates to a swivel faucet of a pressurized working machine. Background technique [0002] Petroleum is a fluid mineral buried deep in the ground. At first, people called oily liquid minerals produced in nature petroleum, combustible gas natural gas, and solid combustible fuel minerals as asphalt. With the in-depth study of these minerals, it is recognized that they are all hydrocarbon compounds in composition and are related to each other in origin, so they are collectively called petroleum; [0003] Traditional devices have the following disadvantages: [0004] At present, when the hydraulic operation machine is performing liquid circulation operation and sand washing operation, it is necessary to use a winch to lift the hose, and use a pump truck to pump liquid through the hose to the bottom of the well. However, the existing faucet will rotate with the oil pi...
