    摘要: The present invention regards a device designed for injection of fluids in a well bore, typically an offshore well bore for petroleum production and gas injection/gas lift system for fluid injection. The device comprises a outer hollow housing with an internal body moveable within the outer housing which in a first closed position is closed with a metal to metal seal system between the outer housing and the internal body, which internal body is operated by pressure differential across the internal body. The internal movable body is connected to the outer hollow housing by means of a retainer key. The retainer key comprises a shear arrangement and is arranged to keep the valve in a fixed closed position, where fluid pressure is to overcome the pretension of the retainer key in order to open the device. When the device is shear opened, it can be kept in this open position as the retainer key is locked to the outer hollow housing.

    摘要: The present invention relates to a device which can be used in an offshore or onshore oil and/or gas well for the purpose of increasing the production of the well. The device comprises an outer structure in which a first and a second pressure-actuated bellows device are arranged, the first and second pressure-actuated bellows device, via a support means, being in fluid communication with each other. The support means is fixedly mounted internally in the outer structure, the support means thereby delimiting an open and a closed space for respectively the first and the second pressure-actuated bellows device, wherein the closed space is filled with a fluid under pressure, whilst the open space is in fluid communication with a surrounding fluid.

    摘要: The present invention relates to a valve device comprising an external structure with a longitudinal axis and a valve seat, and a valve body mounted movably inside the external structure. The valve device comprises a first bellows device permitted to be moved in a substantially radial direction, in fluid connection with a first fluid, and hydraulically connected to a second bellows device permitted to be moved in a substantially axial direction. The second bellows device is connected to a first part piston cooperating with a second part piston, thereby giving the second part piston an oppositely directed movement relative to the first part piston, which thereby moves the valve body relative to the valve seat. The invention also relates to a method for operation of a valve device and the use thereof.
