摘要： The invention relates to a process medium-controlled regulating valve for a liquid throughflow regulating means, having a main valve which has a main valve piston (21) with an adjustable stroke in the axial direction and a main valve seat (23) which interacts with the former and delimits an outlet chamber (15) radially on the inside and an inlet chamber (13) radially on the outside, and having a pilot valve for controlling the main valve piston, which pilot valve has, on that side of the main valve piston which faces away from the main valve seat, a control chamber (5) which is flow-connected via a pilot line (1) in the main valve piston to the inlet chamber and via a pressure relief line (31) to the outlet chamber, and has a pilot valve piston (33) which closes the pressure relief line in a closed position, to be precise with the pressure build-up of a closing pressure in the control chamber and with a stroke adjustment of the main valve piston in a closing direction, and opens the pressure relief line in an open position, to be precise with pressure equalization between the control chamber and the outlet chamber and with a stroke adjustment of the main valve piston in an opening direction, wherein a cleaning wire element (3) which is stationary in the axial direction is guided with hole tolerance through the pilot line, and the pilot line can be moved along the cleaning wire element which is guided therein during a stroke adjustment of the main valve piston. According to the invention, the cleaning wire element has an actuating contour (45) which, at least during the stroke adjustment, can be brought into conducting contact with a counter-contour (51) which is configured on the main valve piston, with the build-up of a transverse force (F) which acts on the cleaning wire element.

摘要： A device (1) for regulating flow comprises a main valve operating under differential pressure wherein the main valve has a main flow inlet (112) and a main flow outlet (113). The main flow inlet is equipped with a valve seat (114) over which a main shutter (100) is adjusted in a perpendicular direction to its shuttering plane. The main shutter has a hole (111) on its locking face communicating with a pressure chamber (110) disposed above the main shutter. A secondary control valve (105) regulates small flows through the hole so as to create greater or less pressure within the pressure chamber to close or open the main shutter.

摘要： The invention concerns an air transfer valve which automatically vents accumulated air from pressurized liquid reticulation pipelines or vessels. The valve (10) has a housing (12) which is connectable to the pipeline or vessel. The housing has a first outlet (38) venting to atmosphere and a control chamber (60) which is exposed to internal pressure in the housing via a control chamber inlet. A first valve closure (34) can move to open and close the first outlet. This valve closure is exposed to control chamber pressure tending to move it to close the first outlet and to internal housing pressure tending to move it to open the first outlet. When the housing is pressurized the first valve closure (34) is maintained in a closed position by virtue of an unbalanced pressure force acting on it that is attributable to exposure of the valve closure to atmosphere through the first outlet. There is also a control chamber outlet (36) from the control chamber (60) to atmosphere. This outlet is larger than the control chamber inlet. The valve also incorporates a float (20) in the housing (12) which is arranged to be buoyed up by liquid entering the housing from the pipeline and a second valve closure (24) carried by the float which is arranged to open and close the control chamber outlet (36) in response to movement of the float caused by variations in the level of liquid in the housing. Downward movement of the float (20) in response to a drop in liquid level in the housing (12), attributable to accumulation of air in the housing, causes the second valve closure (24) to open the control chamber outlet (36). This allows the control chamber (60) to vent to atmosphere. The pressure in the control chamber (60) drops relative to the internal housing pressure and creates an unbalanced pressure force on the valve closure (34) which causes it to open the outlet (38). The housing can then vent to atmosphere via the outlet (38).

摘要： Ein erfindungsgemässes Stellglied zum Einstellen eines Flusses von Medien mit mindestens einem Ventil (10, 10'), das gesteuert ist durch einen hydraulischen oder pneumatischen Steuerkreis mit einem Pilotventil (12, 12'), dessen Verschlussteil (36) lediglich zwei Ruhestellungen einnehmen kann, und einem Servoraum (44), zeichnet sich dadurch aus, dass das Verschlusselement (36) des Ventils (10, 10') durch zeitlich modulierte Steuersignale für das Pilotventil (12, 12') eine quasistationäre Stellung zwischen der geschlossenen Stellung und offenen Stellung einzunehmen imstande ist. Dabei sind die Steuersignale für das Pilotventil (12, 12') zeitlich mit einer Frequenz moduliert, die höher, vorzugsweise um ein Vielfaches höher, ist, als das Inverse der Dauer eines Öffnungs- und Schliessvorganges des Ventils (10, 10'). Das Stellglied ist vorzugsweise mit einem membran- oder kolbenförmig ausgebildeten Verschlusselement (36), an welchem stromabwärts ein Schliesskörper (32) befestigt ist, ausgebildet. Um mögliche Durchflussschwankungen in der quasistationären Stellung zu verkleinern, sind die Reaktionen des Verschlusselements des Ventils (10, 10') durch ein besonders grosses Volumen des Servoraums (44), eine verkleinerte Durchführung (56) beim Zufluss und eine Verbindung (58) mit kleinem Innendurchmesser zum Abfluss des Mediums aus dem Servoraum (44) und einen durch Formgebung und Grösse angepassten Strömungswiderstand eines stromabwärts am Verschlusselement (36) befestigten Schliesskörpers (32) verzögert.

摘要： A one touch valve for activating fluid flow between an inlet conduit and an outlet conduit is disclosed. The valve has a flow cylinder (34) defining an inflow chamber (36) and an outflow chamber (38). The flow cylinder (34) an intermediate plate having a center collar (64) with an aperture (68). A flexible diaphragm (50) is provided with a sealing surface in contact with the collar (64) to create a seal. The diaphragm (50) has an edge coupled to the intermediate plate and a small diameter hole (114) providing fluid contact between the inflow chamber (36) and an intermediate chamber (40) A plunger (48) is placed on the diaphragm (50) to create a seal with the opposite surface of the diaphragm. A shaft (46) has one end connected to the plunger (48) and extends through the aperture (106) of the diaphragm (50). Pushing the shaft (46) causes the plunger (48) to separate from the diaphragm (50) creating fluid pressure on the diaphragm (50) contact surface to push the plunger (48) and causing the diaphragm (50) to separate from the collar (64) causing fluid to flow from the inflow chamber (36) through the aperture (114) to the outflow chamber (38).
