Total-sea-depth buoyancy force adjusting integrated valve set

Abstract

The invention belongs to the field of submersible buoyancy force adjusting correlation techniques, and discloses a total-sea-depth buoyancy force adjusting integrated valve set. The total-sea-depth buoyancy force adjusting integrated valve set is of a plug-in mounting structure and comprises a first stop valve, a second stop valve, a third stop valve, a fourth stop valve, a speed adjusting valve and a valve body. The first stop valve, the second stop valve, the third stop valve and the fourth stop valve are mounted in the valve body in a plug-in mounting manner and are sequentially connected end to end to form a bridge type loop. Switching of water injection and drainage working conditions of water ballast space is achieved by controlling the start-stop combination among the first stop valve, the second stop valve, the third stop valve and the fourth stop valve. The speed adjusting valve is additionally mounted in the integrated valve set, and therefore the working conditions of the integrated valve set comprise the seawater pump water injection and drainage working condition and the dump injection working condition at the same time. According to the total-sea-depth buoyancy forceadjusting integrated valve set, interchangeability of the valves is good, the overall structure is compact, and mounting and maintaining are convenient.

Description

technical field [0001] The invention belongs to the technical field related to buoyancy adjustment of submersibles, and more specifically relates to an integrated valve group for full sea depth buoyancy adjustment. Background technique [0002] With the development of science and technology and the continuous deepening of marine research, since the last century, marine science has developed to the stage of the development and utilization of the ocean, and human beings are now using the ocean as a huge treasure house of resources. The pace of human exploration and development of the ocean is also shifting from the offshore to the deep sea. The deep-sea submersible is one of the important equipment for humans to explore the ocean, especially the manned submersible, which can carry oceanographers and scientists to dive to the bottom of the ocean, so as to investigate the topography, landforms, organisms and minerals of the seabed . [0003] The buoyancy adjustment system is a...
