摘要： A valve assembly includes a valve body and a valve member extending through at least a portion of the valve body. The valve assembly also includes a seat pocket forming an annular recess in the valve body and a seat arrangement positioned at least partially within the seat pocket. The seat arrangement includes a lower seat extending radially inward from the annular recess toward the valve cavity axis. The seat arrangement also includes an upper seat at least partially overlapping the lower seat, the upper seat extending radially inward toward the valve cavity axis to contact the valve member along a seat face. The seat arrangement further includes an interface seal positioned along an interface between the upper seat and the lower seat, the interface seal receiving a fluid pressure to drive the lower seat radially outward and into the annular recess.

摘要： A slide valve comprises: a casing having a pair of facing flow channels; a slide plate inserted into and removed from a space between the flow channels; and an annular sealing body slidingly moving in a facing direction of the flow channels inside the casing and coming into contact with the slide plate inserted between the flow channels to bring the slide valve into a closed state. A first sealing member sealing a gap between the sealing body and the inner peripheral wall surface is disposed on an inner peripheral surface of the annular sealing body and a second sealing member sealing a gap between the sealing body and the outer peripheral wall surface is formed on an outer peripheral surface of the annular sealing body.

摘要： A valve is disclosed having a telescoping seat assembly that fits into a pocket or enlargement of a flow passageway through the valve body. An outer seat element seals with the pocket utilizing a plurality of seal assemblies to seal with the pocket whereby pressure may become trapped between the seal assemblies during valve operation under certain unusual conditions. A groove with a tapering or angled surface is provided in the outer seat. A seal ring is disposed in the groove whereby pressure from one side of the seal ring moves the seal along the tapering or angled surface to wedge the seal into contact with the wall of the pocket. Pressure from the other side of the seal ring moves the seal ring along the tapering surface and away from the wall of the pocket so as to be out of sealing engagement thereby permitting bleeding off of the pressure or de-energizing of the seal assemblies.

摘要： There is disclosed a line blind assembly having a pair of tubular members adapted to be connected in a flowline and connected to one another by bolts having nuts on their ends to permit sealing faces on the inner ends of the tubular members to be tightly engaged with sealing faces on the opposite sides of either a disc or a spacer ring upon removal of the other from within the space. A series of circumferentially spaced, hydraulically operable, extendable and retractable actuators are connected at one end to one tubular member and the other end to the other tubular member, so that the sealing faces may be moved toward and away from one another independently of the bolts and nuts.

摘要： A seal device for a gate valve is disclosed, in which annular members facing the front and rear surfaces of a gate valve member having a through hole are coupled to a valve cage by inner and outer bellows, each of the annular members has an annular recess formed on the side facing the gate valve member and closed by an annular mirror surface finished thin plate secured by welding to an opening thereof, the individual bellows are elongated by fluid under pressure supplied into annular spaces defined by the inner and outer bellows, and the annular mirror surface finished thin plates are strongly urged against the gate valve member by the pressure of the fluid forced from the annular spaces into the annular recesses. Edge portions of the annular mirror surface finished thin plates are to be very firmly mounted to the annular members, and the mechanical strength of the thin plates is to be increased. The two annular mirror surface finished thin plates are to be simultaneously brought into contact with the front and rear surfaces of the gate valve member, and are to be urged against the gate valve member with a uniform pressure over the entire circumference.

摘要： A device, such as a damper or valve, for use in closing a conduit against the flow of liquid has a chamber surrounding and opening into the conduit. A blade at one side of the conduit is movable through the chamber from a first position within a bonnet into a conduit-blocking position. Means carried by the chamber side walls surround the conduit and are between the conduit and the blade when in its first position and are operable then to coact to seal the chamber against leakage into it and to seal the blade when in its second position. At least one seal is of a type brought by fluid under pressure from a position out of the path of the blade into its sealing positions and is carried by the side wall enabling the seal to engage the blade face exposed to the fluid flow. Means are provided to deliver fluid pressure to the pressure operated seal when the blade is in either position and to relieve the pressure therein when the blade is to be moved. Means are also provided to maintain a fluid under pressure in the chamber greater than the fluid pressure in the conduit at least whenever the blade is to move from one position to another and to purge the sealing means and prevent leakage from the conduit along the path of the blade. The other of the sealing means may also be a fluid pressure operated seal and similarly controlled or it may be a resilient compressible seal or seals.

摘要： The valve includes a valve member of great diameter provided with an elastomer seal and borne by a carriage allowing its translational motion during the valve-opening or closing movements. An insulating chamber provided within the valve case houses the valve member when the valve is open. A metal bellows is caused by pneumatic jacks to engage the valve member, when the valve is closed. In the open condition, said chamber ensures thermal insulation of the valve member and protects the seal thereof during heating at high temperature of the ultrahigh vacuum vessel components.

摘要： A flat blade that is supported in cantilever fashion as it moves across a flow path to close said flow path, the flow path having resilient sealing means that can be expanded into contact with the two side edges of the blade after the blade has been moved to its closure setting. There is also resilient sealing means that can be expanded into contact with the leading edge of the blade after the blade has been moved to its closure setting. The blade is supported in cantilever fashion at one end by providing said end of the blade with a plurality of pistons slidable in a cylinder.
