Abstract
A GLV-gas lift valve that employs TSMS-two simultaneous mechanical stops, first one when SEWB-single edge welded bellowis fully compressed to solid by valve dome pressureand second mechanical stop where adjustable sealing arrangement with compressible seal, threaded regulating nutand threaded jam nutare compressed against orifice, compressible sealis fully compressed into groove, gapis fully exhausted, dimension L reaches zero, and gapis completely exhausted, providing second mechanical stop between TC balland orifice. Sealing arrangement can be TC-Tungsten carbide ballbutted against orifice, flat, conical or curved sealing surface containing said compressible seal, that is solidly compressed against SEWB or DEWB, thus providing second mechanical stop and sealing fluid flow through GLV. Compressing SEWB/DEWB to full solid protects bellow from high dome pressurewhile 'Fortress Seal™' per U.S. Pat. No. 11,424,732 B2 protects bellow from high injection pressure.
