Definitions

  • the invention has for its object to form an expansion vessel for drinking water heaters and a connection fitting for such an expansion vessel so that a stagnant water volume is avoided.
  • the invention is further based on the object of making it easier to check the expansion vessel.
  • the invention could be implemented in such a way that the entire stream is passed to the drinking water heater through the expansion vessel.
  • An inlet tube protruding from the inlet into the cavity can ensure that a flow is generated across the cavity to the outlet.
  • a pressure loss occurs on the expansion tank.
  • connection fitting has a direct flow channel between the inlet and outlet passing the cavity, the connection fitting continues to produce a flow path parallel to the direct flow duct and through the cavity, and a suction device is arranged in this parallel flow path, through which by means of the flow of drinking water flowing in the direct flow path, a suction can be generated which when tapping Drinking water a flow can be generated via the parallel flow path through the cavity into a downstream part of the direct flow path.
  • the main stream of the tap water flows directly from the inlet to the outlet. Only a secondary flow flows through the cavity of the expansion tank. This side flow is forced by a suction device.
  • the test can be facilitated by providing first valve means by which the parallel flow path upstream and downstream of the cavity can be shut off, second valve means by which the cavity can be connected to a test outlet, and that Housing has a connection for a pressure measuring device for measuring the gas pressure in the gas pressure chamber.
  • the cavity on the inlet and outlet sides can be separated from the system and relieved of the operating pressure of the water. Then the pressure of the compressed gas can be measured unaffected by this operating pressure via the connection, practically the filling valve.
  • Embodiments of the invention are the subject of dependent claims 4 to 12.
  • 10 denotes a housing of an expansion vessel.
  • a membrane 12 is arranged inside the housing 10.
  • the housing 10 can be connected to the system of a drinking water heater (not shown) by means of a connection fitting 14.
  • the edge 12 of the membrane 12 is clamped between a flange 18 of the housing and a flange 20 of the connection fitting.
  • the membrane 12 is bubble-shaped and forms a cavity 22.
  • a compressed gas space 24 is formed between the membrane 12 and the housing 10.
  • a compressed gas can be filled into the compressed gas chamber 24 via a filling valve 26.
  • connection fitting 14 closes off the opening of the housing 10 or the membrane 12 formed within the flanges 18 and 20.
  • the connection fitting 14 forms an eccentric inlet connector 28 and an outlet connector 30 diametrically opposite the inlet connector.
  • An inlet pipe 32 connects to the inlet connector 28.
  • the inlet pipe 32 extends into the part of the cavity 22 facing away from the connection fitting.
  • the inlet pipe is closed at its end face by a plug 34 and has lateral outlet openings 36.
  • the cavity 22 of the expansion vessel is connected to the system of the drinking water heater. This system is complete as long as no drinking water is drawn. If warm drinking water has been drawn off and cold drinking water has subsequently flowed into the system, then this cold drinking water is heated. The drinking water in the closed system expands. The expansion volume is received by the cavity 22. The membrane 12 expands against the pressure of the compressed gas in the compressed gas space 24. The compressed gas is compressed.
  • the expansion vessel 10 is connected to the connection fitting 14 in the system of the drinking water heater so that when hot drinking water is drawn off, the entire volume flow of drinking water, usually the cold water flowing in, flows through the inlet connection 28 into the cavity 22 and flows out via the outlet connection 30 to the drinking water heater .
  • a current flows from the outlet openings 36 across the cavity 22 to the outlet port 30. This prevents the occurrence of a stagnant volume of water in the cavity 22.
  • the water in the cavity 22 is exchanged with each plug.
  • 40 denotes a housing of an expansion vessel.
  • the housing 40 there is a membrane designed as a bubble membrane 42.
  • the bladder membrane is a hollow body made of an elastic material with an inlet opening 44.
  • the inlet opening 44 is surrounded by a thickened edge 46.
  • the housing 40 also has an inlet opening 48.
  • the inlet opening is surrounded by a connecting piece 50.
  • the bladder membrane 42 is attached to the housing 40 with its edge 46 around the inlet opening 48.
  • the bladder membrane 42 forms a cavity 52.
  • a compressed gas space 54 is formed between the bladder membrane 42 and the housing 40.
  • a compressed gas can be filled into the compressed gas space 54 via a filling valve 56.
  • connection fitting 58 is attached to the housing 40.
  • the connection fitting 58 has a connection piece 60 with a flange 62.
  • a union nut 64 is screwed onto the connection piece 50 of the housing 50.
  • the union nut 64 engages over the flange 60 of the connection fitting 58.
  • the union nut 64 has a round wire 66. This round wire sits in an inner groove of the union nut 64 and is in contact with the flange 62 of the connecting piece 60.
  • a sealing ring 68 lies between the connecting pieces 50 and 60.
  • connection fitting 58 has an inlet 70 and an outlet 72 arranged directly next to it. Inlet 70 and outlet 72 are separated by a partition 74. A direct passage 76 is formed in the partition 74 between the inlet 70 and the outlet 72. Drinking water entering inlet 70 predominantly flows directly from inlet 70 to outlet 72. This is indicated in FIG. 2 by arrowheads 77.
  • a return channel 78 is formed coaxially in the connecting piece 60 in the connection fitting 58.
  • the return channel 78 merges into an outlet pipe 80 aligned therewith.
  • the outlet pipe 80 extends into the cavity 52 formed by the bladder membrane 42 into the part facing away from the connection fitting 58 and the inlet openings 44 and 48.
  • the outlet pipe 80 is closed at its free end by a plug 82.
  • the outlet pipe 80 has lateral inlet openings 84.
  • a flow path 86 parallel to the passage 76 is formed from the inlet 70.
  • the parallel flow path 86 contains a flow part 88 with a channel 90, the annular space 92 between the connecting piece 60 and 50 of the connection fitting 58 or the housing 40 and the return channel 78 or the outlet pipe 80.
  • the parallel flow path 86 then runs through the cavity 52, as indicated by arrowheads 94, and then passes through the inlet openings 84 into the Outlet pipe.
  • the bubble membrane has an elongated shape with a substantially cylindrical outer surface and a hemispherical end face. As a result, the flow in the parallel flow path largely fills the cross section of the cavity 52. This ensures a good exchange of the drinking water in the cavity. In the outlet pipe, the drinking water then flows in the parallel flow path 86 into the return channel 78, which opens coaxially in the outlet 72.
  • the return channel forms a nozzle 96.
  • the main flow of the tapped drinking water from the passage 76 flows around the nozzle 96 essentially coaxially. This causes an injector effect.
  • a suction is generated in the return channel 78. This suction causes the secondary flow in the parallel flow path 86 and thus the water exchange in the cavity 52 of the expansion vessel.
  • the first part 98 of the flow part 88 of the parallel flow path 86 and the return duct 78 can be shut off at the same time.
  • the first valve means 98 are best seen in Fig.4.
  • the first valve means 98 contain a ball valve 100 with a valve ball 102.
  • the valve ball 102 is rotatably mounted between two annular valve seats 104 and 106 with spherical bearing surfaces.
  • the cavity-side valve seat 104 consists of two concentric valve seat rings 108 and 110, which are connected to one another by radial webs 112.
  • the outer valve seat ring 110 is sealingly inserted into the bore of the connecting piece 60 and is supported on an inner shoulder 116.
  • the outer valve seat ring 110 is held by a pressure piece 118 screwed into the bore of the connection piece 60.
  • the valve ball 100 has a central through bore 120.
  • the through bore 120 is aligned with the return channel 78 and the central passage within the valve seat ring 108.
  • slots 122 and 124 are provided in the valve ball 100.
  • the center planes of the slots 122 and 124 coincide and through the axis of the through bore 120.
  • the slots 122 and 124 are best seen in Figure 3.
  • the slots 122 and 124 are connected to the channel 90 of the connection fitting 58 and form a section of the flow part 88 of the parallel flow path 86.
  • the slots 122 and 124 are accordingly also connected to the annular passage between the two valve seat rings 108 and 110.
  • an adjusting spindle 126 also engages in the slot 122, through which the valve ball 100 can be rotated about a horizontal axis lying in the paper plane of FIGS. 2 and 4.
  • the adjusting spindle 126 is rotatably mounted in a jacket-shaped extension 128 of the connection fitting 58.
  • a rotary handle 130 is attached to the adjusting spindle 126.
  • the valve ball 100 can be rotated into the position shown in FIG. 3 by means of the adjusting spindle.
  • the adjusting spindle 126 contains radial bores 132 which are connected to a longitudinal bore 134.
  • the longitudinal bore 134 communicates with an outlet 138 via a test valve 136.
  • the radial bores 132 open into an annular groove 140 of the adjusting spindle 126.
  • a channel 142 opens into the annular groove 140, which runs from the forward part 88 of the parallel one Flow path 86 starts from the ball valve 98 on the cavity side.
  • an insert 146 provided with outer ribs 144 is fastened by means of a locking ring 148.
  • the outer ribs 144 are seated on the pressure piece 118 and bear against the inner edge of the sealing ring 68.
  • the connection fitting 58 is also tightened against the housing 40. This has the effect that a pipe section 150, which is located in the valve-side end of the outlet pipe 80 and forms a section of the return channel 78, is tightened against the inner valve seat ring 108.
  • Fig. 5 shows a modified version of the connection fitting.
  • the construction of the expansion tank is the same as in the embodiment according to Fig. 2 to 4.
  • housing 152 denotes the housing of the connection fitting.
  • Housing 152 has an inlet 154 and an outlet 156 aligned therewith. From the inlet, perpendicular to the axis of inlet 154 and outlet 156, there is a flow channel 158 in housing 152.
  • the flow channel 158 forms part of a flow path to the cavity of the expansion vessel and communicates with the annular space 160 between a connecting piece 162 of the housing 152 and a pipe piece 166 surrounding the return channel 164.
  • the housing 152 also forms a return channel 168, which is connected to the return channel 164 in the pipe section 166 via a bore 170 of a ball valve 172.
  • the housing forms a Venturi nozzle 174 aligned with the inlet 154 and the outlet 156 and downstream from the branch of the flow channel 158. Via the Venturi nozzle 174 there is a direct flow path 176 from the inlet 154 to the outlet 156. This flow path 176 bypasses the cavity of the Expansion vessel.
  • a baffle plate 178 is arranged in the flow path 176. This baffle plate 178 is located upstream of the Venturi nozzle 174 in the region of the feed channel 158. The baffle plate 178 projects from the wall of the housing 152 opposite the feed channel 158 and extends perpendicularly to the axis of the inlet 154.
  • FIG Baffle plate 178 essentially through the axis of the flow channel 158.
  • the baffle plate 178 extends over most of the cross section of the inlet 154.
  • the water flow is first deflected in the direction of the flow channel 158.
  • the greater part of the water flow then flows via the Venturi nozzle directly to the outlet 156, and only a part of the flow flows through the cavity of the expansion vessel.
  • the return channel 168 of the housing 152 is connected to the venturi nozzle 174 via a suction opening 180.
  • a water flow is sucked in via the Venturi nozzle 174 and the suction opening 180 and flows through the cavity of the expansion vessel in the manner described in connection with FIGS. 2 to 4.
  • the ball valve 172 essentially corresponds in structure and function to the ball valve 100 from FIGS. 2 to 4 and is therefore not described again in detail here.
