Definitions

  • the invention relates to a heater with a heat generator for heating a heating fluid, with a flow line for dispensing the heating fluid and with a return line for receiving the heating fluid, and with a bypass line that connects the return line to the flow line and with a valve in the bypass line.
  • a heater according to the invention with a heat generator for heating a heating fluid, a flow line for dispensing the heating fluid and a return line for receiving the heating fluid, with a bypass line that connects the return line to the flow line and with a valve in the bypass line is characterized by a device by means of the the valve can be covered by a sliding sleeve and can be secured by means of the sliding sleeve. This means that the valve can be easily replaced. If the sliding sleeve is configured appropriately, the valve also requires no tools interchangeable. If a separate bypass line is used, an internal circuit can be set up quickly and reliably in the event of the heating fluid stagnating if all passages in the heating system are throttled, which counteracts overheating of the heat generator.
  • the bypass line has an interruption that can accommodate the valve and that can be covered by the sliding sleeve.
  • the bypass line is thus actually divided into two.
  • bypass line has a radial stop in the area of the interruption.
  • this radial stop is attached on one side.
  • the bypass line can have seals in areas adjacent to the interruption.
  • a positionally secure insertion of the valve is achieved if the valve has a housing that widens on one side.
  • the valve is a check valve. It can thus be made possible that heating fluid can flow in the bypass line from the supply line to the return line, but the way back is blocked.
  • the opening pressure of the non-return valve can be used to define the pressure difference at which the non-return valve opens and relieves the heating system.
  • the invention also relates to a device for a heater with a sliding sleeve which is able to accommodate a valve and which can be introduced into a bypass line.
  • a heater according to the invention and a device according to the invention are shown and explained in more detail in the following description. It show the figure 1 a schematic representation of a heating system with a heater and the Figures 2 to 4 the device according to the invention in different steps for removing a valve.
  • a heater 10 is shown schematically, which has a heat generator 12 for heating a heating fluid.
  • a heat generator 12 for heating a heating fluid.
  • Such a heater 10 is intended to heat and provide a heating fluid or service water or both.
  • the heating fluid or the service water can be heated continuously and/or fed to a storage tank.
  • a heat generator 12 is a device with which thermal energy can be transferred to the heating fluid or the service water.
  • gas or oil burners or heat exchangers that are part of a district heating system, a solar heating system, a heat pump or the like are suitable for this purpose.
  • the heater 10 has a flow line 14 for dispensing the heating fluid and a return line 16 for receiving the heating fluid.
  • the flow line 14 and the return line 16 are routed to the edge of a housing 18 enclosing the heater 10 and have connections 20 there, via which they can be connected to a heating system 22 .
  • the heating system 22 is only shown schematically here and can be made up of various radiators, underfloor heating systems, storage tanks and the like. Usually these components each have control units via which their filling and throughput can be adjusted.
  • an additional heat exchanger 24 is housed in the heater 10, via which domestic water can be heated, for example.
  • the inlet 26 of the heat exchanger 24 is connected to the flow line 14 .
  • Its output 28 is connected to the return 16 via a three-way valve 30 .
  • the three-way valve 30 can be used to set the heating fluid to flow via the supply line 14 into the heating system 22 and from there via the return line 16 to the heater 10 or that the heating fluid is routed through the heat exchanger 24 .
  • mixed forms are also possible.
  • a pump 32 is provided to drive the heating fluid.
  • the pump 32 sits in the return line 16 within the housing 18 of the heater 10.
  • a bypass line 34 is arranged between the flow line 14 and the return line 16 .
  • the bypass 34 connects the supply line 14 to the return line 16 in such a way that heating fluid can flow from the supply line 14 to the return line 16 under certain conditions.
  • a valve 36 is provided to influence the flow of the heating fluid.
  • bypass line 34 is arranged within the heating device 10 .
  • the bypass line 34a can also be arranged outside the housing 18 (dashed line in figure 1 ).
  • the bypass line 34b is connected to the line of the outlet 28 and thus indirectly to the flow line 14 (dashed line in figure 1 ).
  • the valve is accommodated by a device 38 .
  • the device 38 includes a sliding sleeve 40 which covers the valve 36 and secures it in place.
  • a sliding sleeve 40 is to be understood as meaning a displaceable cover part or a housing part which is displaceable in its position relative to other housing parts. It can be made of plastic or made of metal. In the exemplary embodiment, the sliding sleeve 40 has a wooden-cylindrical shape.
  • the sliding sleeve 40 can be moved at least into a closed position 42 ( figure 2 ) and to an open position 44 ( Figures 3 and 4 ) postpone. In the open position 44, the valve 36 can be removed. It can then be checked, cleaned or replaced.
  • FIG figure 3 the open position 44 is shown.
  • the valve 36 is seated in a recess 48 of the device 38.
  • this recess 48 it is analogous to the direction for opening the sliding sleeve 44 in FIG figure 3 moved to the left. In the exemplary embodiment, this is an axial movement. Then it can be removed radially from the device 38 . This is indicated by the arrow 50 and shown in FIG figure 4 .
  • bypass line has an interruption 52 .
  • This interruption 52 can accommodate the valve 36, which can then be covered and secured via the sliding sleeve 40.
  • valve 36 is reinserted into the interruption 52 in the reverse order and covered and secured with the sliding sleeve 40 after it has been moved axially to the right.
  • the device 38 has a radial stop 54 in the area of the recess 48 .
  • the valve is inserted radially into the interruption 52 until it strikes the radial stop 54 and is then pushed axially into the recess 48. Then it is secured and covered by axial displacement, to the right in the figures.
  • the device 38 has seals 55 in the areas next to the interruption 52 .
  • these are O-ring seals.
  • more complex seals with an H cross-section or seals with soft lips can also be used. It is advantageous if the seals 55 are introduced in such a way that they are assigned directly to the device 38 and are part of the device 38 .
  • the seals seal the entire receiving area when the sliding sleeve 40 is in the closed position 44 in a fluid-tight manner.
  • the sliding sleeve 40 has an expanding area 56 . This allows displacement along the bypass line 34 , with sufficient space being provided by the expanded area 56 to accommodate the valve 36 .
  • the expanding area is shown as a step in the exemplary embodiment. However, it can also be used with bevels 57 (dashed in figure 2 ) will be realized.
  • the valve 36 has a housing 58 which widens on one side.
  • the extension 60 of the housing 58 is dimensioned such that the valve 36 can only be pushed into the depression 48 with the side opposite the extension 60 . This ensures that the valve 36 is always used in the correct position.
  • the extension 60 can be implemented by a correspondingly shaped, flared housing 58 . It is also possible to provide separate additional rings or structures.
  • the extensions can be designed in such a way that they lean against an inner region of the sliding sleeve 40, for example on the slopes 57, and are centered over the sliding sleeve 40.
  • the sliding sleeve 40 can also press the valve 36 into the recess 48 in such a constellation.
  • the valve 36 is a check valve 62. It is arranged in such a way that a pressure equalization from the supply line 14 to the return line 16 can take place. In the opposite direction, the check valve 62 blocks.
  • the check valve 62 has a fault-loaded valve member 64, which is pressed onto a valve seat 66 in its closed position. The pressure difference at which the check valve 62 opens is defined by the force with which a spring 68 presses the valve member 64 onto the valve seat 66 .
  • the check valve 62 can be designed in such a way that this force and thus the pressure difference at which the check valve 62 opens can be adjusted.
  • the invention also relates to the device 38 for a heater 10, which is able to accommodate a valve 36 with a sliding sleeve 40. It can be introduced into a bypass line 34 as a separate component.
