Abstract:
An unclogging filter apparatus (100) has an irrigation outlet and a flushing outlet. (109) A filtering element (118) moves between at least an operational position and a flushing position. When the filtering element (118) is in the operational position substantially all of the fluid flowing into the apparatus is directed out the irrigation outlet, while the filtering element (118) is disposed for removing a particle from the fluid flowing into the apparatus. When the filtering element (118) is in the flushing position, the filtering element is disposed for flushing the particle out the flushing outlet (109).
Abstract:
Die Erfindung betrifft eine Ventilvorrichtung für einen hydraulischen Kreis (10), die den zulaufenden Volumenstrom in mindestens zwei vorausbestimmte Teilströme zur Versorgung hydraulischer Verbraucher (V 1 , V 2 ) des Kreises (10) teilt, die mindestens eine Druckwaage (16) aufweist sowie mindestens eine Blende. Dadurch, dass die Blende als variable Blende (32) ausgestaltet ist, die mittels eines Proportional- Magneten (34) derart ansteuerbar ist, dass deren Öffnungsfläche sich verändert, ist eine Art Stromregler realisiert, der den geregelten Volumenstrom umschalten und/oder definiert proportional einstellen kann.
Abstract:
Structures and methods are provided for improving the distribution of fluids between exit flows from a split junction, such as a tee-junction. The improved distribution of fluids can result in a more equal distribution of both gases and liquids between the exits of the junction. The improvement can be provided by using a baffle structure, such as an annular baffle structure, upstream from the desired junction. The baffle structures can improve the distribution of fluids in the exit flows in various manners, such as by reducing the amount of vorticity or "swirl" in the input flow to the junction or by reducing the separation of gases from liquids within a flow.
Abstract:
A high purity water delivery system has a reservoir (40) of purified water. A distribution line (42) extends downstream from an outlet (44) of the reservoir to a return (46) of the reservoir. A plurality of delivery stations each include an outlet (54') and a diverter (102; 102'; 102"; 102" '). The diverter has an upstream inlet port (104) along the distribution line and a downstream outlet port (106) along the distribution line. The diverter has a supply port (108) downstream of the inlet port and a return port (110) downstream of the supply port. The diverter has a flow restriction (112; 112'; 216) between the supply port and the return port. Each delivery station includes a flow control valve (56') between the outlet on the one hand and the supply port and return port on the other hand.
Abstract:
Die Erfindung betrifft eine Druckabschneidungsventileinheit (34) mit einem Wechselventil (36), das einen ersten Eingangsanschluss (39) und einen zweiten Eingangsanschluss (40) aufweist, die in Abhängigkeit von den an den Eingangsanschlüssen (39, 40) herrschenden Drücken mit einem Ausgang verbindbar sind. Das Wechselventil (36) weist ein Wechselventilschließelement (45') auf, das in einer ersten Endposition den ersten Eingangsanschluss (39) mit dem Ausgang verbindet und das in einer zweiten Endposition den zweiten Eingangsanschluss (40) mit dem Ausgang verbindet. Das Wechselventilschließelement (45') ist in einer zwischen den beiden Endpositionen befindlichen Stellung arretierbar und in dieser arretierten Position ist der erste Eingangsanschluss (39) mit dem zweiten Eingangsanschluss (40) verbunden.

Abstract:
Methods and apparatus for a bi-directional dual chamber orifice fitting comprising a body with a chamber in fluid communication with a flow bore. The fitting also comprises an orifice supported by an orifice plate carrier that is selectably disposable in the bore. In the preferred embodiments, the lower chamber includes two passageways connecting the chamber to the flow bore. One passageway is located on either side of the orifice plate. Each passageway may also be equipped with a check valve to permit flow in only one direction through the passageway. In operation, the passageway on the upstream side of the orifice would allow fluid to flow into the lower chamber while the passageway on the downstream side would prevent flow back into the flow bore.
Abstract:
The invention relates to a valve device (1), equipped with a narrowed section (8) which supplies a device with seal gas. In order to make the device independent of inlet pressure, the invention is characterised by a pressure reducer (6) which is positioned between the inlet (2) and the narrowed section (8) of the device.
