摘要： A valve assembly includes a piston housing inside a flow duct between an inlet and an outlet so as to form an annular flow passage between the flow duct and the piston housing. The piston housing is axially aligned with a center axis of the flow duct. A piston is inside the piston housing and is configured to extend downstream of the piston housing in a closed position. A spring biases the piston to the open position. A fluid chamber is between the piston and an upstream end of the piston housing. A control opening extends through the upstream end of the piston housing and fluidically communicates with the flow duct and the fluid chamber. A control piston and a control spring are inside the piston housing. The control spring biases the control piston toward a first position that obstructs the control opening.

摘要： A bleed valve system includes a bleed valve, a valve regulator, a valve actuator and a reverse flow relief valve. The bleed valve is opened and closed to control a flow of bleed air from an upstream inlet to a downstream outlet. The valve regulator provides a servo pressure used to regulate the position of the bleed valve, and the valve actuator is mechanically connected to open/close the bleed valve based on the servo pressure provided by the valve regulator. The reverse flow relief valve compares a pressure upstream of the bleed valve to a pressure downstream of the bleed valve and in response to the downstream pressure exceeding the upstream pressure creates a fluid communication path between the servo pressure and an ambient pressure to decrease the servo pressure such that the bleed valve is closed.
摘要翻译：泄放阀系统包括排放阀，阀调节器，阀致动器和逆流溢流阀。泄放阀被打开和关闭以控制从上游入口到下游出口的排出气流。阀调节器提供用于调节放气阀位置的伺服压力，阀门执行器机械连接，以根据阀调节器提供的伺服压力打开/关闭排气阀。反向泄流阀将排放阀上游的压力与泄放阀下游的压力进行比较，并且响应于下游压力超过上游压力，在伺服压力和环境压力之间形成流体连通路径，以降低伺服压力使得排气阀关闭。

摘要： A valve flange joint includes a valve flange and first and second duct flanges. The first and second duct flanges include respective first and second mating portions. The first mating portion includes a first duct rim, a first duct face in contact with a first face of the valve flange, and a first slot. The second mating portion includes a second duct face in contact with a second face of the valve flange, and a second rim. In an embodiment, the valve flange includes a tab that extends in an axial direction through the first slot and includes an inner surface radially inward of an outermost portion of the second mating portion. In another embodiment, a first thickness is defined between the first flange face and the second flange face. Second and third thicknesses are also defined for the first and second mating portions. The three thicknesses are substantially similar.

摘要： A bleed valve includes a housing with an inlet coupled to an outlet by a duct, a guide tube with an orifice fixed in the housing between the inlet and the outlet, a piston, and baffle. The piston is slideably supported on the guide tube and is movable between an open and a closed position, the duct fluidly coupling the inlet and outlet in the open position, the duct fluidly separating the inlet and outlet in the closed position. The orifice fluidly couples the inlet and outlet in the open and closed positions to move piston between the open and closed positions according to differential pressure between the bleed valve inlet and outlet. The baffle is slideably supported by the guide tube to set the differential pressure at which the piston moves between the open and closed positions. Gas turbines and differential pressure adjustment methods are also described.
