Abstract

The invention relates to the technical field of oil well valves, and discloses a ternary wellhead combination valve for a water mixing process of an oil well valve. The ternary wellhead combination valve comprises an oil inlet pipeline, wherein a master control valve is mounted in the oil inlet pipeline; and the other side of the oil inlet pipeline is fixedly connected with an oil conveying pipeline. According to the ternary wellhead combination valve for the water mixing process of the oil well valve, a device motor connecting piece and a motor connecting piece positioning sleeve are clamped and fixed, so that the connecting stability and sealing property of the device motor connecting piece can be driven; meanwhile, the outer part of the device motor connecting piece is connected with a motor, the motor is started to drive a device bevel gear II to rotate, and a device screw rod is driven to rotate through a linkage relation; and meanwhile, a spiral pipeline is mounted on the outer part of the screw rod, so that materials conveyed in the oil inlet pipeline can be continuously driven to move to the other side, the phenomenon that the materials are difficult to convey due to more impurities in an oil well is prevented, and the effect of increasing power during oil conveying is improved.

Description

technical field [0001] The invention relates to the technical field of oil well valves, in particular to a three-way wellhead combination valve for the water mixing process of the oil well valve. Background technique [0002] In oil wells, there is a phenomenon of internal water seepage, which makes it necessary to remove the internal liquid in the early stage when pumping oil from the wellhead. For this reason, a ternary wellhead combination valve with water mixing process for oil well valves has been developed. Different valves are adjusted to facilitate segmental extraction of waste liquid and oil, and improve the existing three-way wellhead combination valve for the water mixing process of oil well valves. [0003] In the existing ternary wellhead combination valve in the water mixing process of oil well valves, there are fatigue damages when the valve is used and impurities inside the oil field during use, which makes it easy to cause blockage, and it is convenient to m...
