Abstract:
A filter device includes four couplers attached to four sides, and a casing attached to bottom. A filtering material receptacle may be attached to the casing for filtering the water. A valve member is rotatably received in the housing, and includes six openings and four spaces and to communicate the openings of the valve member with each other, and includes two passageways for communicating with two openings of the valve member. The filtering material may be flushed with the water, and may be forced to change ion or to be cleaned with cleansing agent simply by rotating the valve member relative to the housing.
Abstract:
A fluid containing system, as in a filter, for toxic or hazardous fluids is provided with rotatable base seals that can be alternatively positioned to permit the flow of fluids from the filter supply line, passing through the filter or, alternatively, the filter supply line can be sealed shut to prevent fluid leakage when the filter is removed. A third filter seal position is provided, wherein a cleaning fluid, for example compressed air, can be supplied to the filter in order to remove excess fluid from the filter prior to removal. An alternative embodiment permits removal of the filter and sealing of the supply line by rotating the filter and seal assembly about the supply line access to save space or to facilitate changing the filter. The fluid containing system can also function as a fluid sampler, or to add materials to the fluid system.
Abstract:
Eine Filtervorrichtung mit mindestens einem Filterelement (3), das in einem Filtergehäuse (19, 21, 61) aufgenommen ist, das über mindestens zwei Anschlussstellen (A, B) verfügt, die abwechselnd der Zufuhr von Unfiltrat und der Abfuhr von Filtrat dienen, wobei mittels einer Umsteuereinrichtung (15) der über die Anschlussstellen (A, B) jeweils sich in der Richtung umkehrende Fluidstrom das Filterelement (3) in nur einer vorgebbaren Richtung durchquert, ist dadurch gekennzeichnet, dass die Umsteuereinrichtung mindestens eine Ventilschiebereinrichtung (15) aufweist, deren Ventilkolben (17), in einem Ventilgehäuse (27; 63) geführt, vom jeweiligen Unfiltratstrom in der zuordenbaren Anschlussstelle (A, B) angesteuert über die Rohseite (23; 77) des Filterelementes (3) den Fluidstrom zu derjenigen Anschlussstelle (A. B) freigibt, die an die Reinseite (F) des Filterelementes (3) angeschlossen ist.
Abstract:
A modular filter system using replaceable filter cartridges includes matching adaptor rings in the filter head and on the filter cartridge placed at selected circumferential positions to ensure proper cartridge fit and to provide a proprietary cartridge construction for selected users. The adaptor rings operate only to control cartridge to filter head fit and are not used to drive the rotary valve spindle.
Abstract:
A filter for fluids of the type that comprises a hollow body which is closed by a head (12) and contains at least one filtration medium (13), the head comprising a hollow external cap in which through holes (15, 16, 17) are formed which are suitable to connect a corresponding number of ducts and in which a distribution element (18) with through channels can rotate. In the external dome there are at least three through holes (15, 16, 17) and the distribution element (18) is shaped so as to form at least four channels (19, 20, 21, 22): at least one first channel (19), which is a through channel which lies at right angles to this axis of rotation; at least one second channel (20) which has an exit port at an internal regional of the at least one filtration medium; at least one third channel (21) which has an exit port at a corresponding region which lies outside the at least one filtration medium; at least one fourth channel (22) which has the same configuration as one of the three preceding ones; the channels being suitable to arrange themselves in present combinations which are determined by the relative position of the dome and the distribution element, in connection with respective holes of the at least three through holes.
Abstract:
A filter assembly primarily intended for use in fluid analyzer systems for particulate or coalescing filtration of fluids includes a filter assembly (12) having a base element (11) with all port openings (35-37) in the base and with the port openings arranged so that the assembly can be mounted in a variety of selected positions.
