摘要： A modulating flow control valve assembly having a bypass extending from the face of the valve through the valve and the means by which the valve is mounted within the valve body. As the valve moves within the valve body in response to fluid demands, the amount of bypass fluid is varied accordingly by controlling the amount of fluid permitted to pass through the bypass.

摘要： The preferred embodiment of the invention disclosed herein includes a main check valve movable between a fully closed and fully open position in response to the flow requirements from a pressure source to a demand system and including an intermediate position wherein the flow to the demand system corresponds to a predetermined minimum flow from the pressure source. Also included is a bypass valve for controlling the flow from the pressure source to a recirculation system. In the fully closed position of the main check valve, the bypass valve is in a fully open position whereby a predetermined minimum flow from the pressure source is maintained; in the intermediate position of the main check valve, the bypass valve is closed and remains closed between the intermediate position of the main check valve and its fully open position. Operation of the bypass valve is responsive to movement of the main check valve and is controlled by fluid from the inlet side of the main check valve which acts on opposite faces of a piston associated with the bypass valve. The pressure on one face of the piston is controlled by a pilot valve of the throttling type which valve is responsive to the position of the main check valve such that pressure on the one face of the piston is vented when the main check valve is closing and is increased when the main check valve is opening.
摘要翻译：本文公开的本发明的优选实施例包括主要止回阀，其响应于从压力源到需求系统的流动需求而在全闭合和完全打开位置之间移动，并且包括中间位置，其中到需求系统的流量对应于来自压力源的预定最小流量。还包括用于控制从压力源到再循环系统的流量的旁通阀。在主止回阀的完全关闭位置，旁通阀处于完全打开位置，从而保持来自压力源的预定最小流量; 在主止回阀的中间位置，旁通阀关闭，并在主止回阀的中间位置与其完全打开位置之间保持关闭。旁通阀的操作响应于主止回阀的运动，并且由来自主止回阀的入口侧的流体控制，该主止回阀作用在与旁通阀相关联的活塞的相对面上。活塞一面的压力由节流阀的先导阀控制，该阀对主止回阀的位置作出响应，使主活塞关闭时活塞一面的压力被排出，当主止回阀打开时增加。

摘要： The preferred embodiments of the invention disclosed herein comprise a first or main control valve means and a second valve means including a pressure reducing valve arrangement both controlled by the same actuator means. Initial operation of the actuator means opens the second valve means and its further operation opens the first valve means. The valve means are constructed and arranged so that inlet pressure provides a force tending to close the first valve means and another force which tends to open the second valve means whereby proper sequential operation of the valves is assured and so that the force acting to open the second valve is transmitted to the first valve when it is being opened.
摘要翻译：本文公开的本发明的优选实施例包括第一或主控制阀装置和包括由相同致动器装置控制的减压阀装置的第二阀装置。致动器装置的初始操作打开第二阀装置，并且其进一步操作打开第一阀装置。阀装置被构造和布置成使得入口压力提供趋向于关闭第一阀装置的力和另一个倾向于打开第二阀装置的力，从而确保阀的适当顺序操作，并且使得作用于打开第二阀在打开时传递到第一阀。

摘要： A valve body member and various insert assemblies usable with the body member to form steam traps of different types are disclosed in this application. The body member includes an internally threaded, generally cylindrical recess extending inwardly from an outer surface and terminating in an end face, an inlet passage communicating with the recess through a passageway terminating in the end face of the recess, and a discharge passage also communicating with the recess. An annular rib is formed on the end face of the recess around the passageway and includes a surface on which is seated a first sealing ring clamped in place by a first bearing surface of the particular insert assembly used to form the steam trap; an annular seat is formed on the outer surface of the body member around the cylindrical recess and this seat receives a second sealing ring which is clamped in place by a second bearing surface of the insert assembly. All of the insert assemblies further include a threaded portion that cooperates with the internally threaded portion of the recess to retain the insert assembly and the body member in assembled relationship. Certain of the insert assemblies include a plurality of parts which are retained in assembled relationship by a retaining ring arrangement to facilitate assembly and disassembly of the insert assembly, and the body member and all of the insert assemblies are arranged to retain the first sealing ring adjacent the first bearing surface to facilitate removal and insertion of the first sealing ring on the annular rib.
