摘要： Un appareil à clapet de retenue (10) empêche le refoulement du fluide dans une conduite d'écoulement de fluide et comprend un clapet de décharge amélioré qui draine le refoulement de fluide depuis une zone située entre une vanne d'arrêt amont (12) et une vanne d'arrêt aval (16) si l'écoulement normal est coupé et si la vanne d'arrêt aval (16) n'arrive pas à assurer une fermeture hermétique sans égouttage. Pendant un écoulement normal, le clapet de décharge est fermé. Le clapet de décharge comprend un ''joint d'étanchéité à peler'' formé par un diaphragme flexible (46) qui ''pèle'' en se retirant pour ouvrir l'orifice (24c) du clapet de décharge et laisser passer au travers de ce dernier le refoulement depuis le clapet de retenue aval (16) vers l'atmosphère.

摘要： Backflow preventer apparatus (10) for preventing backflow of fluid in a fluid flow line includes an improved relief valve which drains fluid backflow from a zone between upstream (12) and downstream check valves (16) if the normal flow is shut off and downstream check valve (16) fails to seal drip tight. During normal flow, the relief valve is closed. The relief valve includes a ''peel seal'' formed by a flexible diaphragm (46) which peels to open the relief valve orifice (24c) for backflow therethrough from the downstream check valve (16) to the ambient atmosphere.

摘要： A diaphragm control valve provides substantially straight-through fluid flow, which enables a high-flow capacity with minimal pressure loss. The non-planar diaphragm (200) when standing in a non-stressed state, is substantially an annulus that assumes a shape with a cross section that extends from a first attachment bead (220) substantially radially in a first direction through a first curve (210) continues substantially non-radially in a second direction through a second curve (212) and continues in a substantially radial direction terminating in a second attachment bead (228), such that the diaphragm does not fold back upon itself. The diaphragm (200) is both axially non-overlapping and rotationally symmetrical.

Further, the present invention provides substantially straight-through fluid flow which enables a high flow capacity with minimal pressure loss. The non-planar diaphragm of the present invention, when standing in a non-stressed state, is substantially an annulus that assumes a shape with a cross section that extends from a first attachment bead substantially radially in a first direction through a first curve continues substantially non-radially in a second direction through a second curve and continues in a substantially radial direction terminating in a second attachment bead, such that the diaphragm does not fold back on itself. That is to say, the diaphragm is both axially non-overlapping and rotationally symmetrical.

摘要： A control valve for regulating flow of fluids has an actuator located in a control chamber connected to a valve body. The valve body defines a flow passageway passing through an opening. A plug is associated with the actuator such that movement of the actuator from a rertacted position towards an extended position displaces the plug towards the opening. The valve also includes a guide-and-seat insert which proivdes a valve seat interconnected with an attachment collar via a number of plud guides. When the plug is displaced b the actuator, the plug slides in contact with at least two of the plug guides. When the actuator moves to its extended position, the plug closes against the closure surface of the valve seat so as to block the passage of fluid from an inlet to an outlet of the valve.

摘要： The pressure differential metering device of the present invention is generally deployed as a flow restrictor placed in the valve inlet so it will create a desired differential pressure to signal a pilot valve, for example, that drives the main valve to limit the flow rate through the valve. The pressure differential metering device of the present invention is deployed across the valve inlet port, with its central axis perpendicular to the direction of fluid flow. The flow restriction element of the present invention may be configured in a variety of sizes to create a desired restrictive cross section to the flow, thereby creating the required differential pressure signals for the valve instrumentation and control. The flow restriction element is configured with upstream and downstream apertures that are the openings to passageways to the corresponding upstream and downstream end-ports. The end-ports provide connection arrangements for the control system of the main valve instrumentation.

摘要： The dual actuator valve of the present invention deploys both the primary and secondary actuator elements in a single, common control chamber. Therefore, the present invention provides a dual actuator valve having dimensions that are the same as, or similar to, the dimensions of a single actuator control valve. It will be appreciated that the actuator elements may be of diaphragm type or piston type actuator elements. The primary actuator element is mechanically linked to the valve plug and regulates the flow though the valve, while the secondary actuator element remains in a fully open position. Should the primary actuator element fail to operate the valve due, for example, to diaphragm rupture, failure of the primary control system, or any other reason, the secondary control system activates the secondary actuator element, which then effects movement of the primary actuator element thereby resuming flow regulation or closure of the valve as necessary.
摘要翻译：本发明的双致动器阀将主致动器元件和辅助致动器元件都布置在单个公共控制室中。因此，本发明提供了具有与单个致动器控制阀的尺寸相同或类似的尺寸的双致动器阀。应当理解，致动器元件可以是隔膜式或活塞式致动器元件。主致动器元件机械地连接到阀塞并调节通过阀的流量，而辅助致动器元件保持在完全打开位置。如果主致动器元件由于例如隔膜破裂，主控制系统的故障或任何其他原因而不能操作阀，则次级控制系统激活辅助致动器元件，其然后实现主致动器元件从而根据需要恢复阀的流动调节或关闭。
