More Information
Summary:A gas lift valve has a flow restrictor, a valve part on one side of the flow restrictor, a flow deflector and a tubular member on another side of the flow restrictor, and a flapper valve on the side of the flow restrictor where the tubular member is located, the flapper valve being adjacent to the tubular member. When fluid flows into the gas lift valve at sufficient pressure, the valve part opens, the fluid flows through the flow restrictor and acts on the flow diverter thereby moving the tubular member and opening the flapper valve. The tubular member extends though the opening the flapper valve covered. L'invention concerne un clapet de poussée de gaz qui comporte un restricteur d'écoulement, une partie clapet sur un côté du restricteur d'écoulement, un déflecteur d'écoulement et un élément tubulaire sur un autre côté du restricteur d'écoulement, et un clapet à battant sur le côté du restricteur d'écoulement où l'élément tubulaire est situé, le clapet à battant étant adjacent à l'élément tubulaire. Lorsque le fluide s'écoule dans le clapet de poussée de gaz à une pression suffisante, la partie clapet s'ouvre, le fluide s'écoule à travers le restricteur d'écoulement et agit sur le dériveur d'écoulement déplaçant ainsi l'élément tubulaire et ouvrant le clapet à battant. L'élément tubulaire s'étend à travers l'ouverture du clapet à battant couvert.
