摘要： An example valve includes: (i) a valve body defining a first longitudinal bore therein and including a first inlet, a second inlet, and an outlet; (ii) a cage disposed in the first longitudinal bore coaxial with the valve body, where the cage defines a second longitudinal bore therein; (iii) a pin mounted and extending longitudinally within the second longitudinal bore at an end of the cage adjacent to the first inlet; and (iv) a spool shiftably mounted within the second longitudinal bore and configured to move axially therein to shift between a first position and a second position. The spool includes a blind hole formed at an end thereof facing the pin and coaxial therewith, such that as the spool shifts from the second position to the first position, a portion of the pin is received within the blind hole of the spool.

摘要： A solenoid valve includes a main valve that controls a flow rate of a working fluid, a sleeve in which the main valve is slidably inserted, and a solenoid unit that displaces the main valve. The sleeve includes a slide support and a large-diameter portion. The main valve is slidably supported by the slide support. The large-diameter portion is closer to an open end of the insertion hole than the slide support is, and has a diameter larger than an outer diameter of the slide support. The sleeve is fixed inside the insertion hole by causing the large-diameter portion to be pushed against the valve block by the solenoid unit.

摘要： A chemical injection valve can include a valve stem, flow between sections of a flow passage being prevented and permitted in respective closed and open positions of the valve stem, a resilient primary seal that prevents flow through an annular gap surrounding the valve stem in the closed position, and a bypass passage in communication with the annular gap and a flow passage section, and in communication with another flow passage section in the open position. A chemical injection system can include a chemical treatment pumped through a chemical injection valve and into an interior of a tubular string, and the chemical injection valve including a valve stem and a bypass passage extending between a flow passage section and an annulus surrounding the valve stem, the annulus being positioned longitudinally between a resilient primary seal and a metal secondary seal.

摘要： A valve component and method for controlling fluid flow comprises a body having a first surface and a second surface. At least one tortuous flow channel extends between the first surface and the second surface. The flow channel is at least partially defined by a floor portion and a ceiling portion. The body is formed as one-piece by additive manufacturing to concurrently define the flow channel as a void space. At least one of the floor portion and ceiling portion is disposed at an acute angle relative to a plane containing a layer of material forming the body.

摘要： In one embodiment, a constant-flow valve assembly is provided that comprises a first fluid passageway carrying fluid at a first fluid pressure, a piston chamber, and a second fluid passageway connected to the chamber and carrying fluid at a second fluid pressure. A third fluid passageway is configured to carry fluid at a third fluid pressure. An adjustable valve member is provided between the chamber and the third passageway to provide constant fluid flow to the third passageway. An adjustable restrictor assembly is positioned between the first and second fluid passageways. An inlet portion of the restrictor assembly receives fluid at the first fluid pressure and directs the fluid to a restrictor. An outlet portion receives fluid from the restrictor and directs the fluid to the second fluid passageway at the second fluid pressure. The restrictor is movable to adjust the position of entry and exit portions relative to the inlet and outlet portions to adjust a fluid flow rate through fluid pathway to the second fluid passageway, thereby adjusting the flow rate through the valve assembly.

摘要： An assembly for limiting excess flow includes a housing having an internal bore that defines a seat. A cage is positioned within the internal bore and includes an upstream end and a sealing surface at a downstream end. A back plate with at least one magnet is seated within the internal bore upstream of the cage. The cage moves away from the back plate when a predetermined flow condition is exceeded such that the sealing surface engages the seat.

摘要： A balanced globe valve assembly includes a housing having an inlet and an outlet and a cage disposed within the housing between the inlet and the outlet. The cage includes a valve seat and at least one port formed therein. The balanced globe valve assembly further includes a valve member disposed within the cage and coupled to the housing. The valve member is movable within the cage between an open position in which the valve member is spaced from the valve seat and a closed position in which the valve member is seated within the valve seat so that the valve member blocks the at least one port. The valve member has a small opening formed therein to balance the valve member. A method of controlling a flow of fluid through a balanced globe valve assembly is further disclosed.
