In particular, the abovementioned device (10) comprises a main body (1) within which there is a shaped stem (16) on which a helical spring (17) runs, which is suitable for moving a valve element, which is constituted by a body including a cylinder (18), which has at least one lower projection, and at least one sealing diaphragm (19) which is coupled to the outlet hole (6) of the tank (4).
Abstract:
Die Erfindung betrifft eine Armatur (28) zum Umschalten von Fluidwegen, insbesondere für Anlagen mit einem Drucktauscher (29). Der Drucktauscher weist in wechselnder Richtung durchströmte Rohre (30) auf. Das Gehäuse (11) der Armatur umfasst ein Einlassstück (2), ein Auslassstück (3) und ein Anschlussstück (1) für ein Rohr (30). Die Armatur weist mindestens einen Absperrkörper (17, 18) auf, der mit einem Stellantrieb (8, 10) verbunden ist. Der Stellantrieb (8, 10) steht mit einer Steuereinrichtung in Verbindung, die dazu eingerichtet ist, einen Fluidfluss zwischen dem Einlassstück (2) und dem Anschlussstück (1) oder zwischen dem Anschlussstück (1) und dem Auslassstück (3) herzustellen. Im Einiassstück (2) und im Auslassstück (3) ist jeweils ein Absperrkörper (17, 18) angeordnet. Die Absperrkörper (17, 18) sind zur Variation der Größe von Durchflussöffnungen axial verschieblich.
Abstract:
A high range flow valve for precise supply of both low and high flows. The valve comprises two or more plungers (11, 12) movable inside a housing (30) wherein the movement of each plunger relative to an adjacent plunger or the housing gradually opens or closes a flow opening and thus determines a flow area. Each plunger controls a different flow rate range. Two such valves can be combined in one housing whereby temperature and supply rate can be controlled, for both low and high supply rates.

Abstract:
A device for a flow regulation and a measuring of a medium in a heating or cooling system, which includes a thermal unit valve, which comprises a valve (1) with measuring nipples (7 and 8) and an insert (6), the flow parameters of the valve being obtained by a veil having a geometry (30), designed in a special way.
Abstract:
Device to intercept a fluid, used along a pipe (11) in correspondence with a join of an offtake (12) in order to divert therein a desired quantity of fluid. The interception device comprises at least a bushing (13) screwed to the pipe (11) and a regulation screw (17, 117) coaxial to the bushing (13). In an intermediate position between the bushing (13) and the regulation screw (17, 117) a threaded sleeve (16) is provided, which includes radial holes for the passage of the fluid, a first outer threading (15) with which it is screwed to the bushing (13), and a second inner threading (24), of the standardized type, in which the regulation screw (17, 117) is screwed.
Abstract:
Disclosed are a valve, a gas turbine system and a method for controlling the valve. The valve comprises a valve body (1), a primary closing member (2) which is assembled in the valve body (1) is rotatable to change its opening degree for modulating the flow volume of fluid passing through; a primary actuating member (3) connected with the primary closing member (2) for rotating the primary closing member (2); a secondary closing member (4) which is located within the primary closing member (2) is rotatable to change its opening degree for modulating the flow volume of fluid passing through; a secondary actuating member (5) connected with the secondary closing member for rotating it independent of the primary closing member. The combination of the primary closing member (2) and the secondary closing member (4) reduces overshooting and oscillation of valve control and improves control stability. The primary closing member (2) can modulate flow volume with big steps while the secondary closing member (4) can modulate flow volume with small steps. The smaller control step of the secondary closing member (4) also brings precise control.
Abstract:
Ein Ventil, insbesondere vorgesteuertes Proportional-Wegesitzventil, mit einem Ventilgehäuse (7), das einen Fluideinlass (21) und einen Fluidauslass (23) aufweist, wobei der Fluidstrom zwischen Fluideinlass (21) und Fluidauslass (23) durch einen Hauptkolben (27) regelbar ist, wobei auf einer Rückseite (29) des Hauptkolbens (27) eine Vorsteuerventilkammer (37) vorgesehen ist mit einem durch eine Betätigungseinrichtung (69) bewegbaren Vorsteuerventilschließglied (33), mit welchem der Fluidstrom zwischen der Vorsteuerventilkammer (37) und dem Fluidauslass (23) regelbar ist, wobei zwischen dem Fluideinlass (21) und der Vorsteuerventilkammer (37) eine Zulaufblende (3) angeordnet ist, ist dadurch gekennzeichnet, dass im Hauptkolben (27) in einem Ablauf zwischen Vorsteuerventilkammer (37) und Fluidauslass (23) ein Maximalvolumenstromregler (5) vorgesehen ist.
Abstract:
The control valve according to the invention is for use in liquid-carrying systems. It comprises a valve housing (1) having an inlet side (17) and an outlet side (18), said valve housing being provided with a pressure maintaining arrangement for maintaining a constant differential pressure between the inlet and outlet sides, as well as an amount control arrangement for setting the maximum flow amount through the valve and adjustment of it. The control arrangement comprises two cylinder shell elements (2 and 3) cooperating in the flow path, both having material removed from otherwise overlapping areas, thereby generating an uncovered area (25) in the flow path of the control valve. The outer cylinder shell element (3) is stationarily rotatable relative to the valve housing, while the inner cylinder shell element (2) may be rotated by means of a rotatable handle (13), whereby a larger or smaller opening (25) between the cooperating cylinder shell elements (2 and 3) may be provided. Both cylinder shell elements (2 and 3), which cooperate with the seat hole (8) of the valve housing, may also be displaced (26) in the axial direction, resulting in an increase or a decrease of the generated opening (25). Thereby, the flow amount may be adjusted prior to the presetting, e.g. by means of an actuator.
Abstract:
A valve body contains both a shut off valve (139) and a metering valve (132) in flow communication with one another, the shut off valve (139) and the metering valve (132) both being controlled by rotation of a crank pin (131) inside a keeper body (152) and driven by electric motor (111). The metering valve has a conical portion (132) with a groove (162) to allow a small flow even when the conical portion (132) is shut against its valve seat (135). Movement of the crank pin (131) from one position to another (through an arc of slightly less than 180 degrees) will cause either or both the shut off valve (139) and the metering valve (132) to open or close. The valve is designed for use in monitoring pressure, and controlling water supply in a household.
