摘要： A pressure equalization valve for a treatment tool (51) movable in a completion string (12). The valve comprises a cylindrical valve body having an axial bore (110) in fluid communication with the treatment tool (51). A cylindrical shuttle (112) is provided axially and sealably movable in the axial bore (110). The shuttle (112) is operable between a closed position and an open position. When a flow rate of the fluid flowing from the treatment tool (51) exceeds a preset rate to overcome the spring (114) biasing, the shuttle (112) shifts to the closed position. When the flow rate from the treatment tool (51) drops below the preset rate, the shuttle (112) is biased to the open position.

摘要： A priority flow regulator (100) comprises a valve assembly (1) which is supported by a housing (2) at one end and confines an electro-magnetic actuator (11) at the other end. The housing (2) has an inlet port (54), an outlet port (6), and a regulated port (5). The valve assembly includes a hollow cage (7) that cooperates with a cavity (2a) formed in the housing (2) to define a plurality of internal chambers (3,4,52), a hollow compensating spool (9) slidably arranged within the cage (7) between rows of cross-sectional holes (8a,8b) formed in the cage (7), a hollow guide member (10) slidably arranged within the compensating spool (9) and having cross-holes (15a) formed therein, and regulating and dampening spools (12,15) slidably arranged within the guide member (10) at opposite ends thereof. The internal chambers of the housing communicate with respective ports formed in the housing to provide a priority flow configuration as well as a reverse flow configuration.

摘要： An automatic recirculation valve (10) having a body portion (12), a central hub (60) integral with said body portion (12) and inlet (16), main outlet (18) and recirculation outlets (20). A main valve element (28) responsive to flow from said inlet (16) to said main outlet (18) includes a hollow stem (42) forming a bypass valve member (32) through which recirculation fluid flows. A shaft guide bushing (56) surrounding the valve stem (42) and bypass adapter (58) in the bypass outlet (20) provides a recirculation fluid passage and imparts a swirling movement to the recirculation fluid exiting the recirculation outlet (20) to protect the valve body (12) and downstream piping from damage.

摘要： In a flow control apparatus, a fluid pressure is introduced from downstream of a metering orifice to a rear room (32) of a spool (20) while a relief valve in the spool (20) is assembled in advance. A front section (41a) of a relief valve sub-assembly (40) is press fitted to a hole (21) provided on the spool and is opening to rear room (32) of the spool so that a receiving room of a valve body in a relief valve casing (41) communicates to a bypass path (13). A communicating path (41b) provided in a rod communicates to the rear room of the spool through outside of the relief valve subassembly (40). The relief valve casing (41) is received in a receiving hole (21) provided in the spool (20) and a cylindrical room between the relief valve casing and the receiving room is used as a part of a communicating path.

摘要： La soupape de régulation de débit et de pression décrite, qui comprend un premier boisseau (1) dont la position assure la régulation d'un écoulement fluide sortant de la soupape, ainsi qu'un organe de commande (23, MP) qui commande la position du premier boisseau (1), se caractérise en ce qu'un second boisseau (6), indépendant du premier (2) est monté dans une chambre commune (1) avec le premier boisseau (6) de façon à coopérer avec un orifice de sortie (15) par lequel passe l'écoulement fluide de sortie et de façon à être mobile en réponse à une chute de pression dans la section de l'orifice de sortie (15), afin que sa position soit mise en relation avec l'écoulement fluide de sortie, et en ce qu'entre l'organe de commande et le deuxième boisseau est disposé un organe de réaction (22', 24), qui réagit à la position du second boisseau (16) et fournit une entrée à l'organe de commande (23, MP), pour que ce dernier fonctionne comme système de servo-commande. Le premier boisseau (2) comporte deux sections à surface plane (3, 4) qui sont espacées avec entre elles le second boisseau (6). L'organe de réaction comporte une connexion de réaction mécanique (24) avec une servo-soupape (23), ainsi qu'un transducteur (22') produisant un signal de réaction électrique vers un microprocesseur (MP).
