Annular header pipe type bilge system for ocean nuclear power platform

Abstract

The invention discloses an annular header pipe type bilge system for an ocean nuclear power platform, relates to the technical field of bilge systems, and aims to solve the problem of influence on running of the entire system since the header pipe type bilge system tends to leak when a certain segment of pipeline fails in the prior art. In the bilge system, each bilge water suction port is connected with an annular header pipe through a fluid-controlled cut-off check valve; the annular header pipe is partitioned into a plurality of segments through isolating valves; bilge pumps are connected to the header pipe through cut-off valves. The isolating valves are in open states normally; when water is accumulated in a certain cabin and needs draining, the fluid-controlled cut-off check valve and the cut-off valves corresponding to the cabin are opened remotely, and the bilge pump is started, so that bilge water can be drained. The annular header pipe and the isolating valves are provided, so that the redundancy degree of the system functions is increased: when a certain segment of pipeline fails, the failed segment of pipeline can be isolated through the isolating valves, and the header pipe consisting of the rest of the segments of the pipelines can still run normally, the system functions are not influenced, normal running of the system is ensured, and the system reliability is improved.

Description

technical field [0001] The invention relates to the technical field of bilge water systems, in particular to an annular main pipe type bilge water system for marine nuclear power platforms. Background technique [0002] The bilge water system is one of the important support systems for offshore platforms or ships. Regarding the technical requirements for the design of the bilge water system, international conventions and ship or platform classification regulations of various countries have detailed introductions. The main functions of the bilge water system are: 1. During normal operation, it can effectively remove the bilge water generated in the cabin; 2. In the emergency situation of cabin damage, it can effectively and quickly drain water to ensure the buoyancy and stability of the ship or offshore platform. sex. Bilge system reliability is critical to ship or offshore platform safety. [0003] The pipeline layout of the bilge water system in the prior art usually ado...
