摘要： Valve trim apparatus for use with fluid valves are disclosed. An example valve trim apparatus includes a cage to be positioned in a fluid flow passageway of a valve body. The cage has a cage body defining a first end and a second end opposite the first end. The cage has an opening extending through the body between the first end and the second end. A valve seat is positioned in the opening of the cage body between the first end and the second end of the cage body. The valve trim apparatus is to allow fluid flow between the inlet and the outlet when the fluid valve is in a closed position.

摘要： Fluid flow control apparatus for use with fluid valves are disclosed. An apparatus includes a plug for a sliding stem fluid valve. The plug has a first portion slidably coupled to a second portion. The apparatus also includes a seal gland formed in an outer circumferential surface of the plug by the first portion and the second portion. A dimension of the seal gland changes when the first portion slides relative to the second portion to displace a seal disposed in the seal gland. The seal sealingly engages a cage of the fluid valve when the second portion contacts a seat of the fluid valve.

摘要： Fluid control valve including a valve body and an energizing member. The body is engaged with one end of a rotating shaft and moves along an axial direction of the shaft based on shaft rotation. The body opens and closes a first opening by the outer periphery, and one end comes into contact with and separates from a second opening. The member energizes the body on another end side of the shaft. A portion abutting on the second opening and a flow passage in which a fluid flows are at the one end of the body in the case where the first opening is fully closed. Since a valve-closed position of the body can be secured, and fluid flows in the flow passage, when a low flow rate is controlled, a stable flow rate is secured without closing the second opening which is a suction port in a valve-closed position.

摘要： A choke valve body of a valve apparatus includes a lower stem that terminating at a lower end thereof with a plug. A conduit traverses a lower portion of the lower stem between at least one plug aperture traversing the plug to at least one top aperture traversing an upper end of the lower portion. The lower portion is slidably retained within the valve chamber between closed and open positions. A bonnet fixed with the valve body has a bonnet chamber for receiving the lower portion, and a bore with at least one annular seal for slidably retaining an upper portion. A yoke assembly is fixed with the bonnet, terminates at an upper end with a drive mechanism, and includes an upper stem with a threaded upper end that is driven between raised and lowered positions by the drive mechanism, the upper stem fixed with the lower stem.

摘要： A valve assembly includes a sensing device, a main spring, a bonnet located below the sensing device, a piston with a through hole, and a valve stem connected with the sensing device and having a penetrating part through the through hole. The sensing device drives the valve stem to drive the piston. The valve assembly also includes an auxiliary spring arranged between the bonnet and the piston. The penetrating part is longer than the depth of the through hole and the valve stem is slidably coupled in piston. The valve assembly can prevent the valve stem from transferring the force of the main spring to the piston, so as to avoid damaging the valve port, the valve stem, and the piston when the force of the main spring is too large.

摘要： Cage apparatus having fluid passageways to affect flow characteristics of valves are disclosed. An example valve cage includes clustered fluid flow passages. Each fluid flow passage has a first portion connected to a second portion. The first portion tapers towards the second portion and the second portion tapers towards the first portion. The clustered fluid flow passages include a first row and an adjacent second row. The first row and the second row are oriented at a first angle relative an axis of the valve cage to extend along a helically-shaped path on the valve cage.
