Control valve of deep-water blowout preventer

Abstract

A control valve of a deep-water blowout preventer belongs to the field of deep-water oil-drilling equipment. The control valve consists of a guide control valve and an electromagnetic control valve, wherein the electromagnetic control valve is arranged in the guide control valve. The electromagnetic control valve consists of a cable plug (1), an upper valve seat (2), a bolt (3), a gland (4), an electromagnetic valve body (5), a guide valve body (6), a sealing ring (7), an electromagnetic valve body (8), an isolating ring (9), a compression spring (10), a magnetic conductive ring (11), an electromagnetic coil (12), an iron core (13), an electromagnetic coil slot (14), a lower valve seat (15), a filter grate (16), a fastening nut (17), a screw plug (18) and a head contact pin (19). The control valve has the advantages of compact structure, reliable working, long life and reliable sealing. The electromagnetic control valve bodies are not under the action of the deep-water pressure directly. The iron core and a valve core of the electromagnetic control valve are integrated, and the response speed of a control circuit can be greatly improved.

Description

technical field [0001] The invention belongs to the field of deep-water oil drilling equipment, and in particular relates to an on-off hydraulic control valve for controlling the main function circuit of the underwater hydraulic system of a deep-water blowout preventer group. 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 various domestic enterprises cannot 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 for land oil drilling, and the valves ...
