摘要： Valve de contrôle du débit et de réduction de la pression comportant un corps de valve (250) avec une chambre d'entrée (256) et une chambre de sortie (257) entre lesquelles se trouve une plaque de séparation (258). Une pluralité de passages (265) sont formés dans le corps de la valve et espacés circonférentiellement autour de la plaque de séparation (258); ils comportent une partie d'entrée s'ouvrant dans la chambre d'entrée (256) et une partie de sortie s'ouvrant dans la chambre de sortie (257). Les dispositifs de contrôle du débit d'élastomère (266) sont placés dans les passages et réagissent au fluide pressurisé qui y est introduit pour contrôler le débit du fluide à travers les passages (265) autour de la plaque de séparation. La configuration de la valve permet de monter des portes d'entrée et de sortie à l'intérieur des chambres d'entrée et de sortie, qui permettent d'éviter la nécessité d'avoir des robinets-vannes séparés. Un passage de débit auxiliaire peut être formé à travers la plaque de séparation et le débit peut être contrôlé au moyen de ce passage pour accroître la capacité de débit de la valve tout en assurant un contrôle total du débit et de la pression. Des valves d'entrée et de surpression d'air (279) peuvent aussi être installées en tant que parties intégrantes de la valve.

摘要： A coupling for attachment to the end portion of a pipe (60) having circumferentially directed shoulder (3a) in such end portion includes a coupling body (61) which receives the end portion of the pipe (60) therein and a set of jaw members (65) which, after the end portion of the pipe is received in the coupling body, moved to a closer position to engage the shoulder (3a) so that the coupling is locked onto the end of the pipe (60) and the pipe cannot be pulled from the coupling because the jaw members (65) acting against the shoulder (3a) prevent such movement. The coupling can be provided with sets of jaw members (24E-27E) at each end to couple two pipes (1, 2) with end portion shoulders (3a, 4a) or have jaw members at one end and threads (64), flanges (81, 83), or other types of connectors at the other end. Valves (figure 5) or other fittings may be incorporated into the coupling between the ends of the pipes being coupled.

摘要： A flow control and pressure reducing valve has a valve body (250) with an inlet chamber (256) and outlet chamber (257) separated by a partition plate (258). A plurality of passages (265) are formed in the valve body spaced circumferentially around the partition plate (258) and have an inlet portion opening into the inlet chamber (256) and an outlet portion opening into the outlet chamber (257). Elastomeric flow control means (266) are positioned in the passages and are responsive to pressurized fluid introduced therein to control flow of fluid through the passages (265) around the partition plate. The valve configuration allows the mounting of inlet and outlet gates within the inlet and outlet chambers to eliminate the need for separate gate valves. An auxiliary flow passage may be provided through the partition plate and flow controlled therethrough to increase the flow capacity of the valve yet still provide full flow and pressure control. Air inlet and relief valves (279) may also be provided as an integral part of the valve.
