    摘要: The invention is directed to a tubing hanger for a flow completion system which comprises a christmas tree connected above a wellhead housing that includes a central bore in which the tubing hanger is supported, the tubing hanger comprising a generally annular body; a production bore which extends generally axially through the body; an annulus bore which extends generally axially through the body; the annulus bore comprising a generally lateral first branch which is connected to a generally axial second branch; and a closure member which includes a gate that is moveable generally axially across the first branch between an open position in which a hole in the gate is aligned with the first branch and a closed position in which the hole is offset from the first branch.

    摘要: A valve assembly comprising a tubular member (2) having an axial bore (4) which is selectively opened and closed by a gate valve. The gate valve includes a sliding gate (5), a first actuating stem (9,27) engagable with one side of the gate and a second actuating stem on the opposite side of the gate and also engagable with the gate. The actuating stems can move the gate between open and closed positions, and an intermediate position in which the gate can be run into and withdrawn from a support with the tubular member.

    摘要: A shearing type of gate valve (10) having a sleeve (44) of hard wear resistant material in the opening (42) through the gate and coacting with insert rings (46, 48) of hard, wear resistant material in the seat rings (34, 36) for shearing a wire line (50) or tubular member extending through the valve and the gate. The sleeve and insert ring are assembled with the gate and the seat rings in a manner to provide sufficient compression preload thereon so that they are not subjected to tension loads which avoids chipping, breaking or other damage to the sleeve and the insert rings. Preferably the sleeve and insert rings are of tungsten carbide. In two modified forms of the present invention an insert sleeve of hardened, wear resistant material is provided in the opening of the gate and an insert ring of hardened, wear resistant material is provided in one of the seat rings so that the only a single shearing of the cable element is provided so that the short section is not created in the shearing and left in the opening through the gate while it is closed.

    摘要: Tête de puits (1) à débit réglable par l'intermé­diaire d'une vis pointeau (30, 40) disposée entre deux chambres de pression (17, 18) respectivement reliée au réseau et au puits proprement dit. Un dispositif à garde hydraulique (80) permet l'évacuation de l'eau de condensation sans qu'il y ait modifi­cation de la dépression.
