摘要： A flow control device includes a valve body, a first port disposed on the valve body, a second port disposed on the valve body, a gate disposed within the valve body and configured to control a flow of a fluid between the first port and the second port, and a seat disposed between the gate and the valve body, the seat including a first surface configured to form a circumferential seal with the valve body and a second surface configured to form a face seal with the gate. A method includes receiving, by a sealing assembly forming a circumferential seal between a seat and a valve body, a first force from a collar disposed on the seat in response to a first movement of a gate, and moving, in response to receiving the first force, the sealing assembly in a first direction of the first force.

摘要： The present invention provides a gate valve assembly having a valve body with a channel extending from a distal end to a proximal end, a gate configured to be moved from a first position to a second position, the second position being when the gate is positioned in the channel of the valve body between the distal end and the proximal end of the valve body. A seat insert is also provided to be threaded into a pocked of the valve body and a seat is configured to be positioned within the seat insert. A seal is adapted within a groove of the seat insert positioned between the valve body and the seat insert, wherein the seal is a fixed static seal providing no gaps and/or spaces between the seal insert and the valve body allowing no debris to corrupt the seals.

摘要： A valve system having a vacuum valve and a regulating unit is disclosed. The vacuum valve has a valve seat including a valve opening, a first seal surface, and a valve closure for closing the valve opening using a second seal surface. A drive unit coupled to the valve closure is designed to be adjusted to provide respective valve opening states. The regulating unit adjusts the valve opening state by actuating the drive unit based on a currently determined regulating variable and a target variable. The regulating unit has a checking function configured such that a series of states of the valve closure are detected as park of the regulating process, and the states are stored as current regulating data. The current regulating data is compared with specified target regulating data and process information is generated based on the comparison of the current and the target regulating data.

摘要： An embodiment includes a gate valve comprising: a valve body including a cavity coupled to a channel having proximal and distal portions; a gate to seal and unseal the channel; proximal and distal seats adjacent the gate; wherein (a) the proximal seat traverses towards the gate and stops at a first position when the gate is closing and the proximal channel portion is more highly pressurized than the cavity, and (b) the distal seat slides away from the gate and stops at a second position when the gate is closing and the cavity is more heavily pressurized than the distal channel portion. Other embodiments are described herein.

摘要： A gate valve seat seal includes a two-piece seat arranged so that an inner seat moves within an outer piece. The inner seat is moved by a flange where as the flange moves radially inwards the inner seat is moved axially to seal the gate. As the flange moves radially outwards the inner seat is moved axially out of sealing contact with the gate.

摘要： A gate valve system includes a gate valve that has a housing with a first tubular body and a second tubular body separate from the first tubular body. The gate valve has a gate that moves to interrupt or allow fluid flow from the first tubular body to the second tubular body. The system includes a first seat disposed at a first annular reassess and defines an interior channel configured to receive pressurized fluid from a fluid injector. A second seat disposed at a second annular recess defines a second gap with the second annular recess. The second gap receives the pressurized fluid from the interior channel of the first seat to expand the second gap to move toward the surface of the gate to form an emergency seal with the gate as the pressurized fluid expands the second gap.

摘要： A valve system includes a cam that has a shaft portion with an opening configured to receive a motor shaft, where the opening is off-center within the shaft portion. The system also includes a connecting rod assembly mounted to the shaft portion of the cam, where the connecting rod assembly includes a flexible one-piece connecting rod. The system further includes a valve mounted to an end of the flexible one-piece connecting rod such that rotation of cam results in translation of the valve.

摘要： A first cutter is provided on an edge region of a first surface of a gate valve member to be moveable across the flow path with the gate valve member along a first cutting plane. A first seal pocket is defined by a depression in the first surface of the gate valve, wherein a second peripheral seal surface is provided within the first seal pocket. The first valve seat and the gate valve member are axially moveable relative to each other to permit a portion of the first valve seat to become received into the first seal pocket of the gate valve member when said gate valve member is located within its second position to provide sealing engagement between the first and second peripheral seal surfaces.
