Abstract

The invention relates to the technical field of oil field uphole devices, and is a rotary nozzle cover, which includes a central shaft, a valve cover, a nozzle cover, a sealing sleeve and a nozzle frame. The nozzle cover is provided with an installation cavity opening to the left, and the nozzle cover is on the right. There is a liquid outlet that can communicate with the installation cavity on the side, and a sealing sleeve with the left end located in the installation cavity is fixedly installed in the liquid outlet; a liquid inlet that can communicate with the installation cavity is provided on the rear side of the oil nozzle cover, corresponding to the installation at the right side of the liquid inlet. There is a nozzle holder in the cavity. The invention has a reasonable and compact structure and is easy to use. The axial movement of the central shaft is realized by the moving mechanism, and the grease nozzle is pulled out from the sealing sleeve; the rotation of the central shaft around its own axis is realized by the rotating mechanism to realize the replacement of the grease nozzle; The gland prevents the nozzle from detaching from the nozzle frame under the action of reverse pressure, which is stable, efficient and fast.

Description

technical field [0001] The invention relates to the technical field of oil field uphole devices, and relates to a runner type oil nozzle sleeve. Background technique [0002] In the current wellhead oil production and oil testing operations in oil fields, crude oil is collected from the ground, transported to the ground, and then transported to the refinery by pipelines or transport vehicles. Crude oil with too high down pressure cannot be extracted; the currently used choke manifold with nozzle sleeves has the following problems: (1) The operation is complicated, time-consuming and laborious; (2) It affects the efficiency of production, oil testing and other links; (3) It requires Many people operate; (4) It is inconvenient to replace the oil nozzle; (5) The oil nozzle is easy to detach from the oil nozzle frame. Contents of the invention [0003] The invention provides a rotary wheel type oil nozzle cover, which overcomes the above-mentioned shortcomings of the prior ar...
