PILLAR FOUNTAIN AND WATER SUPPLY CONDUIT (EMBODIMENTS)

摘要

The inventions relate to facilities for water take, mainly to pillar fountains from e.g. water pressure network and also to designs of supply conduits as parts, e.g. of said pillar fountains. The claimed inventions are aimed at providing a design of an pillar fountain assembly and a supply pressure water conduit as a part of said facility ensuring higher water quality, better maintenance and operation of pillar fountain and preventing water freezing in the pillar fountain keeping a chance to disconnect the supply pressure conduit from the pillar fountain assembly. The technical result is also aimed at improving removal of residual water after disconnecting the pillar fountain e.g. from the supply water pressure system. To achieve said result there proposed a number of inventions having common inventive idea (embodiments) as a pillar fountain assembly and supplying water pressure conduit as part of the system in three embodiments. A pillar fountain is proposed comprising an enclosure 1 including a water supply pressure conduit 2, water consumption control unit 4 comprising a pressure valve 5 and a power drive device 6. Unlike the near-term analogue, the water supply pressure conduit consists of two elastic pipes or of an elastic pipe and, at least, one rigid pipe enclosed in each other forming a space therebetween for water supply, said space is connected to the pressure valve. The pressure valve 5 is embodied with three branch pipes, the first inlet branch is connected to the power drive device 6, the second inlet branch is designed enabling to a hydraulic connection to the water supply network 3, the third outlet branch is connected to the inlet of the water supply pressure conduit 2. Said embodiment provides ensuring reliability of the water consumption control system and also having a chance to disconnect the supply pressure conduit from the pillar fountain assembly. There also proposed embodiments of the a water supply pressure conduit comprising a tubular element consisting of two elastic pipes (outer and inner); consisting of an outer rigid pipe, an elastic pipe is enclosed therein and a second rigid pipe enclosed into the elastic pipe; consisting of an outer elastic pipe with a rigid pipe enclosed therein.
