摘要： The valve actuator (10) has a movable control element (12) which is typically connected to the valve to be opened/closed and a propulsion device (16) which may be a hydraulically operated piston (16) for moving the movable control element. A resilient element (22) which may be in the form of a spring arrangement has a stroke extending from a first relatively unloaded position to a second relatively loaded position and a transmission mechanism (18) is also provided, where the resilient element is loaded under the action of the propulsion device via the transmission mechanism and is configured to urge the moveable portion of the propulsion device towards the first position via the transmission mechanism when loaded. The transmission mechanism provides a gearing ratio reduction between the moveable portion of the propulsion device and the resilient element.

摘要： A valve seat (10) for use in a valve incorporating a valve gate is disclosed, the valve seat comprising a valve seat body (12) and a biasing device (14) such as a spring (14), the biasing device being integral with the valve seat body. The biasing device and valve seat body may be welded together or may be formed in a single metal workpiece by a machining, casting or forging process. The valve gate and valve seat cooperate to form a metal -to- metal seal within the valve. At least a portion (15) of the valve seat is typically welded to at least a portion of the valve. A pipeline including at least one valve is also disclosed, as is a method of fitting a valve seat to a valve.
摘要翻译：公开了一种用于包括阀门的阀的阀座（10），阀座包括阀座体（12）和诸如弹簧（14）的偏置装置（14），该偏压装置与阀座体。偏置装置和阀座体可以焊接在一起，或者可以通过机械加工，铸造或锻造工艺形成在单个金属工件中。阀门和阀座配合形成阀内的金属 - 金属密封。阀座的至少一部分（15）通常被焊接到阀的至少一部分上。还公开了包括至少一个阀的管道，以及将阀座装配到阀的方法。
