摘要： A check valve including a valve housing defining a pair of valve openings; a pair of flappers pivotably mounted for rotation relative to the housing between an open position in which they permit fluid flow through the respective valve openings and a closed position in which they prevent fluid flow through the valve openings; and a stop element arranged such that the flappers will contact the stop element in their open positions. Each flapper includes a primary flapper element pivotally mounted to a hinge pin that extends across the valve, and a secondary flapper element. The primary flapper element further includes at least one flapper opening formed therethrough. The secondary flapper element is pivotally mounted such that it may rotate relative to the primary flapper element for opening and closing the at least one flapper opening in the primary flapper element.

摘要： A fluid flow control valve (101, 601) includes a housing (106) and a spherical obstructer (107) having a through hole (108), wherein the spherical obstructer (107) is inserted in the housing (106) and is adapted to rotate therein (106) about an axis of rotation (110) between a first position, in which the through hole (108) is substantially coaxial to the control valve to allow the passage of a fluid, and a second position, in which the through hole (108) is substantially transversal to the control valve to prevent the passage of a fluid. The control valve further includes a rotor (111) within the through hole (108), wherein the rotor is adapted to rotate in a continuous manner under the action of a fluid flowing through the control valve, rotating about a second axis of rotation (112) substantially coinciding with the axis of rotation of the spherical obstructer.

摘要： There is a closure member for rotating or reciprocating movement between upstream and downstream passageways of a valve. A device, which consists of two or more elongated tubes whose cross sections form up into one or more files in moving direction of the closure member to divide the upstream passageway into many channels capable of leading the fluid to flow through, is disposed in the upstream passageway of the valve upstream of the closure member, consequently the upstream surface of the closure member can respectively open or close each channel in sequence while the closure member is rotating or reciprocating in the valve.

摘要： A regulation ball valve for a fluid flow in which a ball is rotatable to bring a passage thereof from a limit position of full opening of the valve to a limit position of full closure of the valve and vice versa. Present in the passage are perforated baffles that at least at an intermediate position between the limit positions are passed through by a fluid flow. The perforated baffles include two perforated metal sheets between which a layer permeable to the fluid is disposed. In particular the layer can advantageously be formed of chaotically-disposed filaments as in steel wool.

摘要： A valve having improved inherent flow characteristics, improved noise characteristics, and improved dynamic torque characteristics is provided. The valve includes a disk for controlling fluid flow inside the valve. The disk has a first vane and a second vane disposed relative to the first vane. In accordance with one embodiment, the second vane is disposed along an axis extending from a pivot point of the disk. In such an embodiment, the first vane is disposed offset from the second vane. The first vane and the second vane can be substantially parallel. The valve further includes an upstream indentation for dynamic torque reduction and can include noise and cavitation reducing features on a downstream side of the disk and/or an indentation for dynamic torque reduction in case of a fluid flow reversal.

摘要： A valve assembly comprising a rotary closure element which defines an axis of rotation and is selectively movable between a fully open position and a fully closed position. Mounted to and movable with the rotary closure element is an impedance assembly. The impedance assembly defines an inflow end and an outflow end, and comprises a plurality of fluid passageways of varying noise attenuating capability which extend from the inflow end to the outflow end. Also partially defined by the impedance assembly is a flow opening which extends from the inflow end to the outflow end. A retainer bracket is disposed within the flow opening and is cooperatively engaged to both the closure element and the impedance assembly.

摘要： A valve (1) has a valve housing (2) with an inlet (3) and outlet (4), a valve body (5), provided with an essentially cylindrical passage (6) and pivotally mounted in the housing (2). Essentially plane walls, defining chambers between them and provided with through openings (11; 11′) are arranged in the passage (6). Upon opening the valve the inlet connects solely with one chamber, which via wall openings and intermediate chambers connects with the chamber opposite and the latter with the outlet. During the successive opening sequence of the valve more and more chambers and finally all chambers are made to connect with the inlet and the outlet respectively. The device has at least one pair of intersecting walls (8a, 8b; 9a, 9b, 10a, 10b). These are located in the passage (6), so that two opposing chambers (K1, K4; k1, k9) situated nearest to the inlet (3) and the outlet (4) respectively lie symmetrically in relation to a center plane, in which the central axis (6a) of the passage is situated during the rotational movement vice-versa (5) between the opened and the closed position and vice-versa.
