Oil field valve device and operation method

Abstract

The invention discloses an oil field valve device and an operation method, and particularly relates to the field of oil field valves. The oil field valve device includes a valve body. A valve cover body is detachably installed at the top of the valve body, and an electromagnetic component located in the valve body is integrally formed at the bottom of the valve cover body. Wires electrically connected with the electromagnetic component are installed at the top of the valve cover body. A disassembly rod is installed on the middle part of the valve cover body in threaded and sleeved modes. A seal piston located in the valve body is fixedly installed at the bottom of the disassembly rod. Through the arrangement of a connecting spring, the impact force of crude oil received by a floating ballcooperates with the elastic force of the connecting spring to stir the crude oil at the bottom of the valve body, so that impurities inside the crude oil are dispersed the moment a valve is opened, the impact of metal impurities and sand and stone on internal components of the valve is reduced, the wear of the internal components of the valve is reduced, and the service life of the entire valve isprolonged.

Description

technical field [0001] The invention relates to the technical field of oil field valves, and more specifically, the invention relates to an oil field valve device and an operation method. Background technique [0002] In the field of oil production, the wellhead is an important equipment for oil production. The oil production wellhead is mainly composed of lower flange, large cross, upper flange, small cross and oil well valves. [0003] Among them, the oil well valve, as the central component of adjustment and control, still has many problems. The main reason is that there are a lot of metal impurities and sand in the crude oil, which causes great wear and tear on the valve during the opening process. In addition, when the valve is closed, a large amount of impurities Because of its high density, it settles at the bottom of the valve, causing a large amount of impurities to impact the internal components of the valve at the moment the valve is opened, which greatly increas...

[0003] Among them, the oil well valve, as the central component of adjustment and control, still has many problems. The main reason is that there are a lot of metal impurities and sand in the crude oil, which causes great wear and tear on the valve during the opening process. In addition, when the valve is closed, a large amount of impurities Because of its high density, it settles at the bottom of the valve, causing a large amount of impurities to impact the internal components of the valve at the moment the valve is opened, which greatly increases the wear and tear of the process of closing and opening the valve, and also greatly limits the service life of the oil well valve.
