Oil exploitation adjusting valve

Abstract

The invention discloses an oil exploitation adjusting valve. The oil exploitation adjusting valve comprises an adjusting valve main body, wherein an oil inlet end is arranged at the lower end of the adjusting valve main body; an adjusting device is arranged at the upper end of the adjusting valve main body and comprises a lead screw; a telescopic block is movably connected to the surface of the lead screw; a pressing block is connected to the lower end of the telescopic block; an oil outlet end is arranged at one end of the adjusting valve main body; a buffering cavity is formed in the position, above the oil outlet end, in the adjusting valve main body; the interior of the buffering cavity is movably connected with a telescopic device; the telescopic device comprises a sealing plug; a spring is connected to the upper end of the sealing plug; a clamping groove is formed in the position, at one side of the spring, of the upper end of the sealing plug; one end of the spring in the adjusting valve main body is connected with a fixing plate; and an opening is formed in the upper end of the fixing plate. According to the oil exploitation adjusting valve, the initial threshold pressure can be set in the valve, the flowing-out speed of oil can be adjusted, and meanwhile impurities in crude oil can be prevented from being accumulated in the valve body.

Description

technical field [0001] The invention relates to the field of petroleum exploitation, in particular to an oil exploitation regulating valve. Background technique [0002] Regulating valve, also known as control valve, is the final control element by changing the process parameters such as medium flow, pressure, temperature, liquid level, etc. It is generally composed of actuators and valves. During oil extraction, it is usually necessary to control the flow rate in the oil production pipe; [0003] The patent number is an invention patent of CN 103353003 B, which discloses a regulating valve for oil exploitation, specifically, it includes a valve cover, a valve core, a regulating disc and a valve body. The valve cover includes a cover body and a cylinder arranged at the lower end of the cover body. Shaped cylindrical structure, the cover is provided with a cover body oil inlet; the valve core is located in the cylindrical cylindrical structure; the valve core is provided with...

AI Technical Summary

Problems solved by technology

The regulating valve can effectively reduce various gases and a large amount of water in the crude oil during oil extraction; at the same time, due to the impurities in the crude oil, when the impurities in the crude oil pass through the valve body for a long time, they are easy to accumulate in the valve body, thus affecting the valve body. Diversion process, while reducing the purity of crude oil

[0004] There are some shortcomings in the existing control valve for oil production, the initial threshold pressure cannot be set inside the valve, and the outflow speed of oil cannot be adjusted. In order to solve the above problems, we propose a control valve for oil production
