Description
Technical field
The present invention relates to a kind of offshore drilling platforms special valve, a kind of thimble connector engineering plastics aluminum alloy two leaves that relate in particular to without any obstruction parts such as springs connect muscle vertical check valve.
Background technique
Continue nineteen twenty Venezuela utilizes wooden platform drilling well in lake, Maracaibo, has found after an elephant, and nineteen twenty-two, the former Soviet Union carried out offshore drilling success with trestle near oil field, Baku, the Caspian Sea.After 1936, the U.S. starts to bore first deep-well at the sea in the Gulf of Mexico again, within 1938, builds up in the world marine oil field the earliest., along with the development of welding technique and Iron And Steel Industry, there is the drilling rigs such as steel fixed platform, bottom-supported platform, jack-up unit in 40～sixties of 20 century, marine site in succession that make offshore oil and gas exploitation expand 30 meters of depth of waters to., having there is mobile ocean drilling rig in nineteen fifty, has greatly improved drilling efficiency.Nineteen fifty-one, Saudi Arabia has found the offshore oilfield of maximum in the world.After the sixties in 20th century, along with the development of electronic computer technology and shipbuilding, mechanical industry, build up various large complicated offshore drillings, collection, the defeated facility of storage, promoted developing rapidly of offshore oil and gas exploitation.There are in the world at present nearly thousand offshore drilling platformses, each ocean all over the world.The Gulf of Mexico is the most active greater coasting area of drilling well in the world, at present operation just have more than a 19000 mouthful of well, thing followed offshore field accident also occurs again and again.
As everyone knows, the expense of the each maintenance of offshore drilling platforms system is all surprising, and seawater self contains various corrosivity mixtures, and offshore drilling platforms in use, in crude oil, contain various corrosivity mixtures, oil field in recovery process, moisture and other Korrosionsmediums all in general oil well liquid-producing, the water in crude oil, along with crude oil is vaporized in heating process, increase the gas phase load of pipeline, caused atmospheric and vacuum distillation unit operation fluctuation, when serious, can cause the tower accident of rushing.MgC12 in crude oil and CaC12 can be hydrolyzed to produce has corrosive HCl, and HCl formation hydrochloric acid soluble in water, has very strong corrosive action, causes the corrosion of delivery pipeline system.Crude oil is outwards carried by oil transport pipeline from oil well produced, and the block clearing cost after any oil circuit maintenance or replacing and line clogging is higher, and affects for a long time oil well production.
Any component in offshore drilling platforms system are all wanted to stand seawater corrosion, in offshore drilling platforms system pipeline, the essential one-way valve of all will using completes whole course of conveying, the one-way valve using at present, picture: steel ball type, valve type and gravity type, the major defect of existence is: inside causes owing to being provided with spring the drag losses that generation is larger.Particularly in torrent pipeline, use, once damping spring can not bear torrent, impact generation bias voltage or malfunctioning, just likely cause unpredictalbe accident to occur.
No matter be offshore field or land oil well, the prominent features of well-known slide beam oil rig is intermittence acting, therefore the sensitivity of one-way valve and always become the Pinch technology of this device working life on supporting pipeline with it.
In previous International Patent Application PCT/AU02/00861, described a kind of one-way valve, it transmits malleation, in case backflow.In this control valve unit, a sliding spool is provided, it is connected with bias voltage fin/diaphragm (web), and the movement of this plunger stretches this fin or shrinks.This fin forms a part for a variable volume chamber, to keep malleation.This valve and being for a shortcoming of other one-way valves of great majority of medical domain, this valve is usually included in the sliding spool sliding between open position and closed position.This sliding spool is biased time closed position conventionally, causes leaking.
China's number of patent application: 90108376.3 one-way valves and application number: the sequence fluid one way valve of 91102122.1 low controlling-pressures etc. all exists whole process will overcome Returnning spring resistance.The matching used one-way valves of institute such as self-priming pump also all exist whole process will overcome gravitational resistance, cause additionally increasing energy consumption.
