Abstract

The invention relates to a special valve matched in a pipeline which is used in an oil field and specially used for conveying crude oil, and provides a horizontal flange connector copper alloy valve with a four-vane connection rib and a deformation runner. The horizontal valve comprises a cylinder shaft, a swing valve element, a flange connector valve body, a fastening screw and an outer end cover. According to the improvement, the outer end of an outlet elbow and the outer end of an inlet elbow of the flange connector valve body are provided with connecting flanges, the outer ends of the connecting flanges are provided with flange sealing planes provided with four to eight through bolt holes, the lining plate face side of the valve element inlet of a fan-shaped cylinder body of a valve element is provided with an annular runner opening, the lining plate face side of the valve element outlet of the fan-shaped cylinder of the valve element is provided with a round runner opening, the deformation runner is arranged between the annular runner opening and the round runner opening in a communicated mode, the four-vane connection rib is arranged between the deformation runner cone part contained by the deformation runner and the fan-shaped cylinder body of the valve element in a connecting mode, a plane hardness layer of the valve body inlet and a plane hardness layer of the valve body outlet are made of hard corrosion-resistant copper alloy materials, and the thickness of a single vane of the four-vane connection rib is 1 / 16 to 1 / 18 the diameter of the round runner opening.

Description

technical field [0001] The invention relates to a matching special valve in a pipeline specially used for transporting crude oil in an oil field, in particular to a flange head copper alloy four-leaf even rib variable flow channel horizontal valve without any hindering parts such as springs. Background technique [0002] As we all know, the cost of each maintenance of the oilfield system is staggering, and crude oil contains various corrosive mixtures. During the production of oilfields, the production fluid of oil wells generally contains water and other corrosive media. The oil pipeline is transported outward, and the cost of any maintenance or replacement of the oil circuit and the cleaning of the pipeline after the pipeline is blocked is relatively high, and the production of the oil well will be affected for a long time. [0003] As we all know, the cost of each maintenance of the oilfield system is staggering, and crude oil contains various corrosive mixtures. During t...
