Problems solved by technology

[0003] However, the existing crude oil metering valve cannot realize the function of adjusting, measuring and calculating different types of oil media during use, the applicability of the device is poor, and there is oil gas and oil in the upper part of the oil inside the metering valve tube when the header joint enters the metering valve. The flow rate is too large, resulting in a large measurement error in the later measurement mechanism

Abstract

The invention belongs to the technical field of petroleum transportation monitoring equipment, and discloses a crude oil metering valve. The crude oil metering valve comprises a metering valve pipe, the metering valve pipe is embedded in the middle of the top end of the exterior of the metering valve pipe, an outer valve rod is rotationally installed in the middle of the interior of the metering valve pipe in a sleeved mode, a main valve plate is installed at the bottom end of the exterior of the outer valve rod in a sleeved mode, and an inner valve rod is installed in the middle of the bottom end of the outer valve rod in a sleeved mode. the auxiliary valve plate is installed at the bottom end of the outer portion of the inner valve rod in a sleeved mode, and driving gears are installed on the two sides of the top end of the interior of the metering valve pipe in an embedded mode. The flow of oil in a pipeline can be counted and monitored by metering the rotating speed of the outer valve rod, meanwhile, the auxiliary valve plate can be screwed out of one side of the outer wall of the main valve plate through rotation of the inner valve rod in cooperation with driving of a motor to a driving gear, and the interior of the metering valve body can be equally divided into six parts through cooperation of the screwed-out auxiliary valve plate and the main valve plate; adjusting, metering and measuring of different types of oil media are achieved.

Description

technical field [0001] The invention relates to the technical field of oil transportation monitoring equipment, in particular to a crude oil metering valve. Background technique [0002] Oil and gas fields refer to the sum of oil reservoirs, gas reservoirs, and oil and gas reservoirs in the same area controlled by a single local structural unit. In order to collect and transport these resources to the outside, pumps are needed to output them. In the geological structure, in addition to crude oil, there are usually various gases and a large amount of water in the oil-bearing rock formation. In the process of oil transportation, the pipeline needs to use the crude oil metering valve to monitor and calculate the oil flow. [0003] However, the existing crude oil metering valve cannot realize the function of adjusting, measuring and calculating different types of oil media during use, the applicability of the device is poor, and there is oil gas and oil in the upper part of the ...
