Description
Technical field
The present invention relates to be specifically designed on a kind of oil field supporting special valve in the pipeline of conveying crude oil, relate in particular to without a kind of male connection aluminum alloy two leaves of any obstruction parts such as spring and connect muscle horizontal single-headed valve.
Background technique
As everyone knows, the expense of the each maintenance of oil field system is all surprising, and 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 through 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.
In oil field system pipeline, the essential one-way valve of all will using completes whole course of conveying, the one-way valve using at present, as: 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, impact generation bias voltage or malfunctioning once damping spring can not bear torrent, just likely cause unpredictalbe accident to occur.
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.
