摘要： A multi-cone, multi-stage spray nozzle includes a nozzle body (102), a valve stem (104) with a first valve head (128), and a second valve head (106) attached to the first valve head (128). The first valve stem (104) is biased into a closed position against a valve seat (120) of the nozzle body (102) by a bias device. The second valve head (106) is continuously open. Upon the application of a first fluid pressure, which is less than a threshold fluid pressure, the bias device (108) maintains the valve stem (104) in the closed position while the second valve head (106) is continuously open. And upon the application of a second fluid pressure, which is at least as great as the threshold fluid pressure, the valve stem (104) moves to an open position while the second valve head (106) remains continuously open.

摘要： A valve seat apparatus for use with fluid valves is provided. The valve seat apparatus (302) comprises a seat ring (302), a seal assembly (422) and a retainer (424). The seat ring (302) has an outer surface (402) that includes a first annular recess (414) and a second annular recess (416) adjacent the first annular recess (414) to form a stepped profile (418). The seal assembly (422) is disposed within the first annular recess (414), and the retainer (424) is disposed within the second annular recess (416) to retain the seal assembly (422). The valve seat apparatus is engaged with the cage (314) and the valve body (304). When the valve stem (318) is moved up or down by an actuator, a closure member (316) can open or close the openings (322) of the cage (314) to allow or obstruct the fluid to flow between the inlet (308) and the outlet (310).

摘要： A fluid flow control device (100) includes a valve body (102) defining an inlet (104), an outlet (106), and a fluid flow path (108) extending therebetween, a valve seat ring (116) coupled to the body that defines an orifice through which the fluid flow path passes, a cage (120) coupled to the body that defines an interior bore (122), a control element (130) slidably disposed within the interior bore of the cage, and a particle catcher (140) at least partially disposed within an interior bore of the control element. The particle catcher includes a particle catcher body (142) that defines an inner flow path (144) and at least one particle catcher passage (148) through which the fluid flow path passes. An outer surface (142c) of the particle catcher and an inner surface of the control element form a particle catching portion (150). The at least one particle catcher passage directs the fluid flow path downwardly into the particle catching portion.

摘要： A multi-cone, multi-stage spray nozzle includes a nozzle body (102) and outer (104) and inner (106) valve stems. The nozzle body (102) defines an outer valve seat (120) disposed at its distal end (116). The outer valve stem (104) is slidably disposed in the nozzle body (102). The inner valve stem (106) is slidably disposed in the outer valve stem (104). The inner valve stem (106) occupies an open position and the outer valve stem (104) occupies a closed position upon the application of a first pressure on the distal ends (138, 126) of the inner and outer valve stems. And, the inner and outer valve stems (106, 104) both occupy open positions upon the application of a second pressure that is greater than the first pressure on the distal ends of the inner and outer valve stems (106, 104).
