Definitions

  • the present invention relates to a drinking or service water system with a transfer point from a public supply network and at least one supply line for the supply of water and at least one loop leading to at least one consumer.
  • This ring line is connected to the supply line via inlet and outlet openings, wherein a cross-sectional constriction is provided in the supply line between the outfeed and threading openings.
  • the cross-sectional constriction is designed such that when flowing through the supply line in the loop line a flow is effected, usually due to the Venturi effect.
  • the present invention further relates to a method for assembling such a drinking and service water system.
  • a generic drinking or service water system is for example from the DE 10 2006 017 807 known to the present applicant.
  • several ring lines go from a supply line, which communicates with the interposition of a motor-driven valve with a purge line leading to a discharge point to the dirty water line. With this configuration, it is possible to flush a supply line to dissipate stagnant water there.
  • the drinking or service water system according to the present invention may be a hot water or a cold water system. It is in the drinking or service water systems according to the present invention, in particular to keep ready by a permanent circulation in the loop lines in the area of consumer points regularly fresh water, even if only one loop is used on a strand of the supply line , As a result, the upstream in the flow direction of the supply line or the strand loops are inevitably flushed.
  • the cross-sectional constriction of generic drinking or service water systems forms a bottleneck in the supply line.
  • the present invention is based on the problem of solving the associated disadvantages.
  • a drinking or service water system with the features of claim 1 is proposed by the present invention.
  • This differs from the generic state of the art in that the cross-sectional constriction is formed by a module.
  • This module is inserted in the service position in the supply line and is in a non-use position in a cylinder which extends transversely to the supply line. The module is then movable between the use position and the non-use position. By moving to the non-use position, the flow restriction caused by the cross-sectional constriction can be eliminated through the supply line. The supply line is now freely flowed through. This prevents solids from settling in the cross-sectional constriction and provides the opportunity to purge the supply line.
  • a spindle which cooperates with the module and by the actuation of the module from the use position in the non-use position can be brought.
  • the spindle is usually driven manually and for this purpose preferably has an actuating end, which is formed with functional surfaces for actuating the spindle. These functional surfaces usually allow the attachment of a tool, such as an open-end wrench, a screwdriver or a hex key, to the spindle to rotate it.
  • the spindle is manually operated. However, a motor operation is not excluded.
  • the cylinder is preferably closed by an end cap in which the spindle is rotatably received.
  • the said actuating end of the spindle extends through the end cap.
  • the end cap and the preferably not rising mounted therein spindle and the cylinder are usually coaxial with each other and provided substantially transversely to the extension of the supply line.
  • a simple maintenance or an easy replacement of an optionally damaged or calcified module is proposed according to a preferred embodiment of the invention to releasably connect the end cap with the cylinder. Accordingly, by loosening the end cap, the module can be removed. The module, the spindle and the end cap usually form a preassembled unit. By removing the module after removing the end cap, the drinking or service water system is opened via the cylinder. This opening can be used for the connection of a hose for flushing the drinking or domestic water system or parts thereof. For this purpose, it is proposed according to a preferred embodiment of the present invention to secure the end cap via a union nut on the cylinder.
  • This union nut has a thread which corresponds to the thread of a standard water connection spout.
  • the attachment for the end cap is also designed with a view to a possible connection of a water hose to the drinking or service water system.
  • a standard water connection spout should be understood such a spout, which is available as a stock, for example, in hardware stores or the sanitary trade.
  • Such a water connection spout usually has a union nut with a thread corresponding to the internal thread of the union nut for fastening the end cap.
  • the module engages sealingly in the use position in the cylinder.
  • the module usually has a module jacket, which regularly defines a cylindrical bore whose inner diameter corresponds to the inner diameter of the supply line and surrounds the flow resistance element.
  • This module jacket is usually connected in one piece with a module base, which is sealingly inserted into the cylinder and for this purpose preferably carries on its outer periphery a sealing lip.
  • the module foot is guided like a piston in the cylinder.
  • the module foot is usually dominated on the side facing away from the module jacket by a spindle receiving, in which engages the spindle.
  • the spindle receptacle preferably has an internal thread at least at its free end, which cooperates with the spindle thread.
  • the previously mentioned module jacket is designed so that the inner circumference of the module jacket in the position of use merges into the inner circumference of the supply line free of heels. At least in the wall area of the supply line and at the transition to the module is to pay attention to a loss-free flow as possible.
  • the flow resistance should be adjusted solely by a flow resistance element, which is located in the module. This can be used as a dynamic flow resistance element according to the disclosure of EP 2 233 648 A1 be formed, the disclosure of which is incorporated herein by reference in the disclosure of this patent application.
  • the module is arranged between two shut-off valves.
  • the shut-off valves are preferably three-way valves. These three-way valves preferably form the input or discharge opening.
  • the three-way valves are preferably arranged so that either a Eintechnischs- or Aus effetsö réelle to the input or Ausfädelö réelle and the module is shut off by placing the valves or only the access to the module with open input or Ausfädelö réelle or only the Entrance or Ausfädelö réelle is shut off.
  • the present invention further wishes to specify a fitting for a drinking or industrial water system according to the invention.
  • This valve is essential to the invention and has a housing which has a flow channel of a supply line and a Cylinder forms and has a said cross-sectional constriction forming module, which is transversely movable to the flow channel and is in a position of use in the flow channel and in a non-use position in the cylinder.
  • the housing forms an inlet and a discharge opening for the supply line. Furthermore, the housing forms two connection openings for a loop, whereby the assembly effort for connection of the valve to the drinking or service water system is reduced.
  • the housing preferably has two shut-off valves.
  • the shut-off valves are preferably designed as three-way valves in the manner already described above. They are each between the inlet and outlet opening and one of the connection openings for the ring line and close the module in the position of use between them. As a result, either the module can be depressurized for itself or else the ring lines and the module or finally only the ring lines.
  • the present invention further provides a method for assembling a drinking or service water system of the type mentioned.
  • the drinking and service water system is mounted, i. the supply line and the at least one loop are connected to the transfer point from the public supply network.
  • the commonly installed cross-sectional constriction is removed from the supply line, so that is now available between the threading and Ausfädelö Avenueen the full effective cross-section of the supply line.
  • the system is now flushed, i. Water from the public supply network is introduced into the drinking water or service water system. Any dirt particles remaining during assembly are flushed out of the drinking water or service water system. Since the cross-sectional constriction is removed from the supply line, there is no problem that contamination in the cross-sectional constriction sets and makes them useless.
  • the supply line remains sealed when removing the cross-sectional constriction, which has the advantage that also the removal of the cross-sectional constriction takes place in a closed system, so that the reintroduction of the cross-sectional constriction in the supply line between threading and Ausfädelötechnisch can not lead to an entry of pollution in the system.
  • FIG. 1 shows a longitudinal sectional view through an embodiment.
  • the embodiment has a housing 2 which forms at the ends of a rectilinear flow channel 4 formed by the housing an introduction opening 6 and a discharge opening 8.
  • This inlet and outlet opening 6, 8 serve to connect the housing 2 to a supply line marked with reference numeral 10 and merely indicated.
  • the flow channel 4 continues the supply line 10 in the main flow direction in a straight line.
  • the housing 2 further forms two view at right angles to the flow channel 4 extending and communicating with this ring line connection piece 12, 14, at the ends of each connection openings 13, 15 are provided for a ring line, not shown.
  • Also included in the housing 2 are two three-way valves 16, 18 FIG.
  • the three-way valve 16 forms the Ausfädelö réelle 17, via which a partial flow of the main flow in the supply line 10 is threaded into the loop connection 12 and passed through the ring line not shown through a pipeline system of a wet cell, for example, a hospital or a hotel.
  • the other three-way valve 18 forms a Einfädelö réelle 19 through which said partial flow is combined by the loop to the main flow of the supply line 10.
  • the designated with reference numeral 16 three-way valve is located at the intersection of the flow channel 4 with the loop connection port 12 and adjacent thereto to the introduction port 6, whereas the other, designated by reference numeral 18 three-way valve is located at the intersection of the other ring connection port 14 with the flow channel 6 and thus adjacent to the discharge port 8.
  • a module 20 is accommodated in the housing 2.
  • the module 20 is in FIG. 1 shown in the operating position.
  • a substantially cylindrically shaped module jacket 22 continues the paragraph formed by the housing 2 inner circumference of the flow channel 4 without heels.
  • a flow resistance element 24 is provided, which is described in detail in the applicant EP 2 233 648 A1 is described.
  • the flow resistance element 24 of the illustrated embodiment of the present invention may have the design and dynamic characteristics illustrated therein.
  • a flow resistance element and a static element can be used, which fixedly increases the flow resistance between the Ausfädelö réelle 17 and the threading 19 in the main flow direction.
  • the module jacket 22 is supported by a module foot 26 which is formed with a circular cross-sectional area and sealingly inserted in a cylinder 28 formed by the housing 2 and movable relative thereto like a piston.
  • the module base 26 has for this purpose on its outer peripheral surface a groove into which a sealing ring 30 is inserted.
  • the module foot 26 is surmounted on the side facing away from the module jacket 22 by a spindle receptacle 32.
  • This spindle receptacle 32 is substantially cylindrical and has in the region of its free end an internal thread 34, which in the in FIG. 1 shown use position of the module 20 with the front end of a spindle 36 is engaged.
  • the spindle 36 is rotatably mounted as a non-rising spindle in an end cap 38.
  • the end cap 38 is screwed via a union nut 40 with the cylinder 28.
  • the spindle 36 has an actuating end 42, on the front side of a formed as a hexagon socket 44 bore is provided.
  • the operating end 42 of the spindle 36 further has a collar 46 which is internally supported on the end cap 38.
  • a projecting at the end cap 38 actuating end 42 formed circumferential groove 48 can receive a snap ring with which the spindle 36 on the other side in axial Direction opposite the end cap 38 is secured, so that the spindle 36 and thus the module 20 with the module removed are captive with the end cap 38 are added.
  • the module jacket 22 is received in a circumferentially formed on the housing 2 annular recess 50.
  • This recess merges over a partial circumference of the flow channel 4 into a cylinder chamber 52 surrounded by the cylinder 28, which is sealed off at the end by the end cap 38.
  • this cylinder chamber 52 of the module base 26 is preferably not rotatable about an unshown in the circumferential direction, but held axially movable.
  • a fitting element 54 is provided, through which the position of the end cap 38 is predetermined in the circumferential direction relative to the cylinder 28.
  • the module 20 of the in FIG. 1 shown used position in a non-use position spent in FIG. 2 is clarified.
  • the module 20 is located inside the cylinder 28.
  • the outer peripheral surface of the module jacket 22 is located approximately at the level of the inner peripheral surface of the flow channel 4 formed by the housing 2.
  • the passage through the flow channel 4 is not routed through the flow resistance element 24. A free flow through the flow channel 4 is possible.
  • FIG. 2 is a rinsing illustrated, in which a flow through the supply line 10 alone in the main flow direction, that is done by the flow channel 4. While in the position of use of the module, ie in normal operation according to FIG. 1 the flow resistance caused by the flow resistance element 24 also leads to a certain throughflow of a ring line connected to the ring line connection pieces 12, 14, which connects a wet cell to the supply line 10, results in the position of the module 20 in the in FIG. 2 shown non-use position no pressure difference across the module 20, since this is no longer in the flow channel 4. Thus, a flow in the supply line 10 leads to no flushing of the loop.
  • the three-way valves 16, 18 are pivotable within the housing 2, about an axis which extends perpendicular to the plane of the figures. In the purge mode, the three-way valves 16, 18 each close the ring line connection stubs 12, 14, so that also in this respect any flow through the ring line and thus the connected wet cell is omitted.
  • the in FIG. 2 shown rinsing operation is set, for example, after installation of the drinking or domestic water system to flush out installation-related contaminants and foreign bodies from the drinking or domestic water system. These foreign objects can not be caught in the flow resistance element 24 and are accordingly reliably discharged.
  • FIG. 3 shows the embodiment with shut-off module 20.
  • the three-way valves 16, 18 are set so that a forced flow through the loop takes place.
  • the flow through the supply line 10 is accordingly diverted through the loop connection port 12, 14 and thus through the loop.
  • the module 20 is pressure-free and can be exchanged for maintenance purposes, for example.
  • the union nut 40 must be solved.
  • a hose connector can be screwed, via which a supply of fresh water can be made to a line section of the drinking or domestic water system.
  • FIG. 4 finally shows the embodiment with complete shut-off against the supply line.
  • the three-way valve 16, 18 are set so that the immediately adjacent to the inlet or outlet opening 6, 8 the access to the flow channel 4 and the ring line connection piece 12, 14 move. Thereafter, assembly work can be carried out both in the ring line connected to the ring line stubs 12, 14 as well as on the flow resistance element 24, ie the module 20th
  • the embodiment shown has all functional components in a single housing 2 and can be installed accordingly with little installation effort in a drinking or domestic water system.
  • the housing 2 consists of a housing base 58, which proportionally the ring line connection pipe 12, 14 and the cylinder 28 ausformt, at the ends of each thread or flanges can be arranged for attachment to.
  • the three-way valves 16, 18 upstream or downstream nozzles 60 are screwed into the housing base, which valve elements of the respective three-way valves 16, 18 sealed and movably hold in the housing base 58.
