摘要： A gate valve includes a valve body and a valve cover. The valve body includes a first opening, a second opening, a third opening, a flow passage from the first opening to the second opening, and a gate channel from the flow passage to the third opening. The gate channel has a central longitudinal axis and a ridge defining a perimeter of the third opening. The valve cover can fit over the third opening and, under force on the valve cover, exert a clamping force on the ridge. The clamping force has a first force component perpendicular to the central longitudinal axis and a second force component parallel with the central longitudinal axis. The first force component of the clamping force is toward the gate channel. The ridge includes a first surface configured to mate with a first surface of the valve cover.

摘要： A high temperature gate valve includes a valve body, a valve element configured to open and close a flow path, and a guide member which is provided in the valve body and guides the valve element in an opening/closing direction. The valve body includes a valve body main portion and a bonnet portion. The valve element slides along the opening/closing direction guided by the guide member. The valve element at a shut-off position blocks the flow path by projecting into the valve body main portion, and at an open position retracts into the bonnet portion. The guide member is divided into a plurality of divided guiding elements along the opening/closing direction, and each of the divided guiding elements are welded to an inside of the valve body.

摘要： A gate valve for mounting in a pipeline comprises a valve body and a gate mounted in the valve body so as to be movable between an open position, and a closed position where a valve opening formed in the valve body is closed by the gate. The gate comprises two opposed faces spaced from the transverse plane of the gate, at least one face being provided with at least two seals that each extend around the face one seal being located within the periphery of the other such that both seals, when the gate is in the closed position, seal against a seat of the valve body to seal against the pressure of fluid acting on the gate in use. In one embodiment, a gate has four seals in total, two on the upstream gate face and two on the downstream gate face.

摘要： An apparatus for a gate valve between chambers includes a valve housing defining a flow path. A male valve portion is rotatable on a fixed axis in the housing. The male valve portion including a first male mating surface positioned at a first angle less than perpendicular to the axis. A female valve portion is fixed in the valve housing for receiving the male portion. The female valve portion including a first female mating surface positioned at a second angle matching the first angle. An o-ring seals the male valve portion to the female valve portion when the male valve portion is rotated into the female valve portion. A polished surface contacts the o-ring when the male valve portion is rotated. When the male valve portion is rotated into the female valve portion the o-ring is compressed thereby sealing the gate valve and closing the flow path.

摘要： A high vacuum valve assembly comprising a valve body with an air chamber formed therein. A gate unit is disposed within the air chamber and includes a valve gate portion disposed to mate to a valve seat, the valve gate portion and the valve seat portion each being disposed at the same angle to provide increased sealing force. The gate unit is urged into closure against the valve seat by a first tension source, which may be a spring, and away from the valve seat by a second tension source, which may be compressed gas, such that the gate unit comprises the only moving part of the valve.
