摘要： A tool includes a chamber, a network, a sensor, a tool controller, and a pressure controller. The network carries messages to and from devices on the network. A header portion of a message indicates a sender of the message and at least one intended recipient of the message. The sensor measures a pressure within the chamber. The sensor, tool controller, and pressure controller are on the network. The pressure controller controls the pressure within the chamber in response to measurements provided by the sensor and in response to a set point provided by the tool controller. The pressure controller processes header portions of all messages carried on the network to determine the intended recipients of each message and processes at least part of data portions of both messages intended for the pressure controller and at least some messages not intended for the pressure controller.

摘要： A valve assembly including a body defining a passageway having a longitudinal axis, a rotatable shaft extending into the passageway, generally perpendicular to the axis of the passageway, and a flapper secured to the shaft within the passageway and movable upon rotation of the shaft between an opened position and a closed position. The flapper includes a groove in an outer circumference, and a seal is received in the groove. The seal has an outer circumference greater than the outer circumference of the flapper so the entire outer circumference of the seal contacts a wall of the passageway when the flapper is moved to the closed position. The seal also has an inner circumference greater than an inner circumference of the groove of the flapper such that an enclosed space is defined between the seal and the groove. An aperture provides fluid communication between the enclosed space and the passageway.
摘要翻译：一种阀组件，其包括限定具有纵向轴线的通道的主体，延伸到所述通道中的大致垂直于所述通道的轴线的可旋转轴，以及在所述通道内固定到所述轴的挡板，并且当所述轴在一个打开位置和关闭位置。挡板包括在外周的凹槽，并且密封件容纳在凹槽中。密封件的外周长大于挡板的外周，所以当挡板移动到关闭位置时，密封件的整个外周都与通道的壁接触。密封件还具有比挡板的槽的内周大的内圆周，使得在密封件和凹槽之间限定封闭空间。孔径在封闭空间和通道之间提供流体连通。
