Abstract

Borestreng-volumkontrollventiler og mer spesifikt, borestreng-volumkontrollventiler for forebygging av u-rørseffekt av væskestrømmen i borestrenger. Borestreng-volumkontrollventiler kan omfatte et ventilhus, en ventilmuffe som kan beveges aksialt innenfor et ventilhus fra en lukket stilling til en åpen stilling, en forhåndsbelastningsmekanisme som forhåndsbelaster ventilmuffen til den lukkede stillingen, og et antall trykkporter som lar et differensielt trykk virke på ventilmuffen. Differensialtrykket som virker på ventilmuffen kan være forårsaket av et oppstrøms trykk og et nedstrøms trykk. Ved å la differensielt trykk forårsaket av en væskestrøm virke på en ventilmuffe, kan u-rørseffekt i en borestreng forebygges eller vesentlig reduseres. Fremgangsmåter for bruk er også angitt.
