Description
Technical field
The present invention relates to the generating servicing unit in a kind of island or field, coastal waters, belong to the application of marine energy development technique
Field, particularly relates to a kind of flanged valve evanohm by means of operations offshore platform by appointing spring sea wind generation platform.
Background technology
After 19th-century mankind's generating magnetic force line cutting conductive coil sends electricity, just build up and become electricity with mechanical energy
The power station of energy, such as steam engine generating (being exactly the maximum heat power station of modern generating, geothermal power generation, nuclear power generation), water
Can generate electricity in (hydro electric power station, seawater tide sunset power station), wind power generation, solar electrical energy generation, oil gas generating etc., they such as can
Being divided into the energy resource consumption generating of resource and renewable energy power generation two kinds, make energy generating by resource is above-described fire
The dynamic generating of the power amount of sending out, core, oil gas generating.Regenerative resource be hydroelectric generation, wind-power electricity generation, geothermal power generation, send out at seawater tide sunset
Electricity, solar electrical energy generation etc..
China coast urban industry is flourishing, and populous, electric power resource is in short supply, and island the army and the people's electrical problem is the most prominent.
And the coastline of China is very long, marine resources enrich, and strengthen the exploitation dynamics of marine wind energy, can effectively alleviate coastal cities and island
A difficult problem for small island electric power resource.
Marine wind energy generating be unable to do without ocean platform, ocean platform be at sea carrying out generating electricity, drilling well, oil recovery, transporting something containerized,
Observe, navigate, the movable offer such as construction produces and the structures of living facilities.Can be divided into solid by its architectural characteristic and duty
Fixed pattern, movable and semi-fixed type three major types.The bottom of fixed platform is directly supported also by stake, expansion footing or other structures
It is bonded to seabed, is divided into pile foundation type and gravity type two kinds by supporting situation.Movable platform floats in water or is supported on seabed, energy
Move to another well location from a well location, connect supporting situation and can be divided into end formula and floating type two classes, the most study novelty
Semi-fixed type ocean platform, it can be fixed in deep water, has again high movable, and tension leg type platform i.e. belongs to this type of.
All there is a serious technical bottleneck in the ocean platform of world: anti-sea beat shock-absorbing ability
Difference.Owing to anti-sea beat shock-absorbing ability directly results in maintenance cost height, service life is short.Therefore, it is necessary to prior art
Offshore platform structure improve, use high efficiency buffer shock-absorbing measure, to meet the needs of marine mining.
Cooling pump in Oversea wind power generation plateform system must be equipped with check valve, could solve the diversion of each pump startup
Problem.Currently used check valve, as: steel-ball type, valve-type and gravity type, the major defect existed is: internal owing to arranging
There is spring to cause and produce bigger drag losses.Particularly using in torrent pipeline, damping spring once can not bear torrent
There is bias or malfunctioning in impact, it is possible to causes unpredictalbe accident to occur.Check valve on the most matched pipeline
Sensitivity and service life become the Pinch technology in Oversea wind power generation plateform system always.
