Adjustable ballast self-flowing water injection valve for deep-sea submersible

Abstract

The invention belongs to the field of valves, and particularly discloses a ballast-adjustable automatic flowing water injection valve of an all-sea-depth deep diving vehicle. The ballast-adjustable automatic flowing water injection valve comprises a valve body, a valve sleeve assembly and a valve core assembly; the valve sleeve assembly is embedded into the valve body, and comprises a locating plug, a gland, a valve sleeve substrate and a pressing plug which are arranged from the top down sequentially; a water injection valve outlet and a water injection valve inlet are formed in the locatingplug and the pressing plug respectively; a diversion gap is formed in the upper end of the valve sleeve substrate; a rear part ceramic sleeve and a front part ceramic sleeve are arranged in the valvesleeve substrate; the valve core assembly is arranged in the valve sleeve substrate, and comprises a sealing gland and a valve core; the sealing gland is connected with the upper end of the valve sleeve substrate; the valve core is arranged between the sealing gland and the pressing plug; diversion holes communicating with the diversion gap are formed in the rear part ceramic sleeve and the valvesleeve substrate; a throttling valve plug is arranged at the lower end of the valve core; and an annular pressure reduction gap is formed between the valve core and the rear part ceramic sleeve. Automatic flowing water injection of a ballast-adjustable system can be realized, and the ballast-adjustable automatic flowing water injection valve has the characteristics of high stability, long life andthe like.

Description

Technical field [0001] The invention belongs to the field of valves, and more specifically, relates to an all-sea deep submersible adjustable ballast self-flowing water injection valve, which can be applied to the self-flowing water injection working condition of an all-sea deep submersible adjustable ballast system. Background technique [0002] More than 70% of the earth’s surface area is oceans, and the international high seas account for approximately 49% of the earth’s total area. The survival and development of mankind increasingly rely on the development of vast oceans. Therefore, various maritime countries are competing for exploration and development relative to the ocean. As the deep sea contains rich mineral resources, the development of the ocean has also begun to move from shallow seas to deep seas. Large-depth manned or unmanned submersibles are important carriers for marine development to deep seas. [0003] The adjustable ballast system is an important part of the s...

Problems solved by technology

If the flow is out of control, the buoyancy of the submersible cannot be adjusted accurately. Therefore, deep submersibles at home and abroad are currently using the method of sacrificing efficiency to achieve flow control through seawater pumps.
