摘要： A control valve (1) for controlling liquid flow in a heating and/or cooling installation. The control valve (1) comprises a valve housing (2) with an inlet (3) and an outlet (4), a flow area regulator for regulating a flow area of an entry opening through which the liquid flowing through the control valve (1) from the inlet (3) to the outlet (4) has to pass, the flow regulator comprises at least one valve member (24) that is rotatable between a fully open position that corresponds to a largest possible flow area of the entry opening (53) and a fully closed position that corresponds to the smallest possible flow area of the entry opening, in which the entry opening is essentially closed, a pressure regulating arrangement downstream of the flow area regulator with a pressure chamber (8) upstream of the flow area regulator and downstream of the pressure regulating arrangement, the pressure regulating arrangement being configured for maintaining an essentially constant differential pressure between the pressure (P1) in the inlet (3) and the pressure (P2) in the pressure chamber (8) and a drain passage (54) connecting the pressure chamber (8) to the outlet (4).

摘要： A control valve (1) for controlling liquid flow in a heating and/or cooling installation under command from an actuator. The control valve (1) comprises a flow regulator with a first annular valve member (20) and a second annular valve member (40) that have an axial overlap. The first valve member (20) is manually rotatable relative to the second valve member (40). The axially overlapping portions of the valve members (20,40) define a first inlet opening (52) with a variable circumferential extent and a second inlet opening (53) with a variable circumferential extent. The first inlet opening (52) is axially offset relative to the second inlet opening (53). A third valve member (24) is axially displaceable by the actuator relative to the first- and second inlet openings (52,53) and defines a first control edge (26) associated with the first inlet opening (52) and defines a second control edge (27) associated with the second inlet opening (53). Rotation of the first valve member (20) relative to the second valve member (40) simultaneously changes the circumferential extent of the first and second inlet openings (52,53), in order to manually preset a maximum through-flow area. Axial displacement of the third valve member (24) changes the axial extent of the through-flow area of the first and second inlet openings (52,53), in order to regulate the through-flow area of the first and second inlet openings (52,53) within a range limited by the preset maximum. A differential pressure regulator is provided downstream of the flow regulator.
It is suggested that Fig. 5 is published with the abstract.
摘要翻译：一种控制阀（1），用于根据来自致动器的命令控制加热和/或冷却装置中的液体流动。控制阀（1）包括具有轴向重叠的第一环形阀构件（20）和第二环形阀构件（40）的流量调节器。第一阀构件（20）可相对于第二阀构件（40）手动旋转。阀构件20,40的轴向重叠部分限定具有可变圆周范围的第一入口开口52和具有可变周向范围的第二入口开口53。第一入口开口（52）相对于第二入口开口（53）轴向偏移。第三阀构件（24）可通过致动器相对于第一和第二入口开口（52,53）轴向移动并且限定与第一入口开口（52）相关联的第一控制边缘（26）并且限定第二控制件与第二入口开口（53）相关联的边缘（27）。第一阀构件（20）相对于第二阀构件（40）的旋转同时改变第一和第二入口开口（52,53）的周向范围，以便手动预设最大通流面积。第三阀构件（24）的轴向位移改变了第一和第二入口开口（52,53）的通流区域的轴向范围，以便调节第一和第二入口开口（52,53）的通流面积 52,53）在由预设最大值限制的范围内。在流量调节器的下游提供差压调节器。建议图5与摘要一起发布。
