A differential deep water blowout preventer control valve

Abstract

The invention relates to a differential deep water blowout preventer control valve, which belongs to the field of deep water oil drilling equipment. The differential deep water blowout preventer control valve comprises an electromagnetic control valve and a guide valve, wherein the electromagnetic control valve is arranged inside the guide valve; an electromagnetic control module is fixed inside the electromagnetic control valve; the valve body of the electromagnetic control valve is provided with three oil channels; and the make-and-break of the oil channels are controlled through the position of a valve core arranged on the junction of the three oil channels. The differential deep water blowout preventer control valve has the advantages: a differential structure is formed by the lower end of the valve core of the electromagnetic control valve and the upper end of an iron core under the action of a high-pressure working fluid simultaneously, so that the problem of the influences of excessively high rigidity requirement of a spring and the pressure fluctuation of the working fluid during the use of the high-pressure working fluid on the static performance of the electromagnetic control valve can be solved. Working pressures are applied to the two ends of the iron core and the valve core of the electromagnetic control valve, so that the response speed of an entire hydraulic control system can be increased, and convenience is brought to modular installation; and most materials of the valve body are made of stainless steel, so that high corrosion resistance is achieved, work is reliable, and the service life is long.

Description

technical field [0001] The invention belongs to the field of deep-water oil drilling and production equipment, and relates to a differential deep-water blowout preventer control valve. Background technique [0002] Due to the shortage of oil resources in the world, especially onshore oil resources are becoming less and less, all countries are turning their attention to the sea. However, due to the slow development of the domestic offshore oil drilling equipment manufacturing industry, with the increasing depth of working water, the existing equipment of domestic enterprises can no longer meet the needs of offshore development. Moreover, most of the various equipment for offshore drilling depends on the wellhead, which is costly and subject to many technical restrictions. [0003] At present, various valves on the domestic market are mainly used in land oil drilling and production equipment, and the valves on oil drilling and production well control devices used in harsh env...
