DESCRIPTION:
BRIEF SUMMARY
The invention relates to an apparatus for directing, controlling, measuring and monitoring liquid streams, in particular for a membrane-type water conditioning apparatus, and to a water conditioning apparatus.
In a membrane-type water conditioning apparatus, for example a water conditioning apparatus operating according to the principle of reverse osmosis, untreated water is passed over a synthetic membrane under high pressure. The substances present in the water are selectively retained by the membrane, whereby the water is separated into pure water (permeate) and water containing the retained substances (concentrate).
In known membrane-type water treatment apparatus the liquid streams are passed through tubes, whereby the functional elements required for control, regulation and monitoring, such as regulating valves, control valves, pressure sensors, pressure switches, flow meters and the like are each fixedly installed in the tube system by means of screw connections.
This conventional arrangement is disadvantageous in that it requires a disproportionate amount of assembly time and a lot of space for the whole arrangement. Moreover, the change of individual functional elements or the insertion of additional functional elements is difficult and may eventually be realised only by changing the entire arrangement.
It is the object of the invention to provide an apparatus for directing, controlling and monitoring liquid streams, in particular for a membrane-type water treatment apparatus and a water treatment apparatus itself, which are designed in a space-saving and compact manner, require little time for assembly and repair work and provide easy operation while providing high versatility.
This object is achieved by an apparatus according to claim 1 and by a water conditioning apparatus according to claim 13, resp.
Further developments of the invention are defined in the subclaims.
Further features and advantages of the invention will be apparent from the description of embodiments in connection with the Figures. In the Figures:
FIG. 1 is a perspective representation of the inventive apparatus seen from its front side, with the component parts being separated in the manner of an exploded representation;
FIG. 2 is a perspective view of the inventive apparatus seen from the back side;
FIG. 3 is a partially sectional view of a portion of the inventive apparatus and
FIG. 4 is a schematic representation of a membrane-type water conditioning apparatus wherein the flow channels are schematically indicated.
As shown in the FIGS. 1 to 3 the inventive apparatus comprises a plate-shaped main body 1 made of resin or metal and having a rectangular cross-section with a thickness d. The main body 1 has one plate surface, defined as front side 2, provided with a plurality of groove-shaped, elongate recesses or milled depressions 10a, 10b, 10c . . . each extending parallel to a respective one of the outer edges of the main body 1 and forming individual portions of flow channels for a liquid flowing in the main body 1. The recesses 10a 10b, 10c, . . . have a rectangular or circle segment-shaped cross-section. The main body is formed of red bronze or glass fibre reinforced resin, of brass (MS), of polypropylene-random (PP-R) or stainless-steel. When using MS or red bronze and highly concentrated waters the main body is upgraded or coated to match the medium.
Furthermore, the main body 1 has, in addition to the groove-shaped recesses 10a, 10b, . . . forming the flow channels, a number of further recesses 12a, 12b, 12c with rectangular cross-section, the recesses being formed at the front side 2 and having edges aligned parallel to the outer edges of the main body 1. The recesses 12a, 12b, 12c serve the purpose of receiving fittingly dimensioned slide members or receiver pieces 13 for instruments.
As shown in FIG. 2 the main body has, on its back surface 3 opposite to the front side 2, a plurality of connections A, B, C, D, E, F, G, H defined by apertures formed at predetermined positions in the back surface 3. The connections s
