Definitions

  • the present invention relates to a draft regulator with an openable control flap as a pressure difference-dependent effective closure element of a secondary air inlet opening of an exhaust pipe, so that depending on the prevailing in the region of the secondary air inlet opening difference between the pressure in the outer space and the pressure in the interior of the exhaust pipe, the opening width of the secondary air inlet opening is changeable the draft regulator has an outside space side which, in the installed state of the draft regulator, faces the outside space of the exhaust gas line, a cover for the control flap arranged on the outside being present.
  • Tension regulators of the type considered here are known in various embodiments and widely used in exhaust systems of building heaters in use. They are also referred to as Switzerlandbegrenzer and as secondary air devices.
  • Tension regulators serve to keep the train in a chimney or chimney during firing operation of a connected fireplace essentially constant or for a constant pressure adjustment in the exhaust gas line at changing operating conditions of the fireplace or in fluctuating weather conditions, such as outside temperature, wind, etc. to care.
  • the pressure adjustment made by the draft regulator is done by adding secondary air into the exhaust system.
  • a conventional draft regulator has a pot-shaped housing, which is connected with its open end to a respective exhaust pipe, so that the interior of the cup-shaped housing to the interior of the exhaust pipe is open, the junction between Werreglergeophuse and the exhaust pipe is sealed to the outside.
  • On the outer end side of the Buchreglergeophuses is the secondary air inlet opening and the control flap, which is mounted in a swinging or pivoting manner about a horizontal axis and which in its closed position closes the secondary air inlet opening with edge overlap. In this closed position of the control flap then no secondary air flows from the outside space through the secondary air inlet opening into the interior of the exhaust pipe or into the interior of the Werreglergeophuses connected thereto.
  • control flap will change from its closed position to an open position in accordance with the pressure difference.
  • the secondary air inlet opening is more or less wide open, so that a more or less large amount of secondary air can flow into the exhaust pipe. If the pressure in the exhaust pipe increases again relative to the external pressure at the control flap, the control flap can tilt back about its pivot axis into the closed position.
  • Known draft regulators are connected in a separate room of a building centrally to the exhaust pipe.
  • a room is in particular the boiler room of the building in which also the fireplace of the (central) heating is installed. Access to this room is usually only allowed to certain persons who have the necessary expertise in the function and adjustment of the tension controller.
  • a draft regulator which comprises a cylindrical housing with rectangular built-in nozzles and a cover arranged on the outside, in the form of a removable, partially open cover.
  • a control flap is pivotally mounted, which verich saut a secondary air inlet opening in the idle state, and these far as a result of the train exerted by the chimney train on it wide.
  • Pull regulators with such arranged on the outside covers for the control flap are also from the patents DE 941 563 C .
  • CH 141 828 A and CH 224 600 A known.
  • the air supply via air inlet openings in the Switzerlandreglergephinuse always takes place directly from the exhibition room of Switzerlandreglers.
  • draft regulators ensure that manipulation of the control damper by unauthorized persons who do not possess sufficient knowledge of the draft regulator is prevented.
  • This allows a draft regulator to be connected to an exhaust pipe even if a separate room for the draft regulator in the building is not available.
  • the draft regulator may be installed in a room that is freely accessible to the occupants of the building.
  • a central fireplace in the building, it is not necessary to provide the draft regulator according to the invention in the space of the central fireplace.
  • a use of a draft regulator is also possible if no central fireplace in the building is present, but several (single) fireplaces distributed to different rooms in the building and connected to a common exhaust pipe or to a common fireplace.
  • the object of the present invention is now to expand the possibility of using a draft regulator of the type mentioned.
  • This object is achieved according to the invention by providing a supply air duct for supplying air into the interior of the cover.
  • This supply air duct preferably leads to a different space than the one in which the draft regulator is mounted. From this other room then air can be fed to the draft regulator and thus the exhaust pipe.
  • the possible use of the invention Buchreglers is increased with it. Especially in airtight rooms, in an operation of a controlled room ventilation, when operating a heat pump or a blower, such as a fume hood, in the room of Werreglers then the Heilzutuhr to the control valve is independent of the air conditions in the room of the Switzerlandreglers.
  • the supply air line may also be provided in addition to openings in the cover.
  • the cover has such a size and shape that the control flap is completely covered by the cover. As a result, a particularly high level of security against damage or improper adjustment of the control flap is given.
  • an adjusting element for adjusting the opening behavior of the control flap is present.
  • this adjustment element By means of this adjustment element, a minimum draft requirement of the fireplace (s) connected to the exhaust pipe can be set. This adjustment is covered by the cover.
  • the adjusting element is thus, like the control flap, protected by the cover from damage or improper adjustment.
  • the cover is formed of a dimensionally stable material. This ensures a particularly good protection of the butterfly valve. A simple bending of the cover is prevented.
  • the cover may be designed in particular box or cup-shaped.
  • the cover can be opened or removed.
  • access to the interior of the tension controller is ensured, for example, to clean it or to change the setting of a concealed behind the cover adjustment.
  • a closing element for closing the cover to an opening or dismantling by unauthorized persons for safety's sake.
  • the cover advantageously has openings, in particular a perforated grid.
  • openings in particular a perforated grid.
  • a building G which has two living rooms S1 and S2 and a basement KE.
  • a first fireplace F1 and in the living room S2 a second fireplace F2.
  • the two fireplaces F1 and F2 are connected to a chimney KA, which serves as an exhaust pipe for the exhaust gases generated by the fireplaces F1 and F2.
  • the building does not contain a central heating to supply the two living spaces S1 and S2. The generation and supply of living spaces with heat takes place through the respective fireplace F1 or F2.
  • a draft regulator ZR is connected to the fireplace KA.
  • the basement here is a common room for the residents of the Building G. It is shared by them for various purposes, such as storage.
  • the basement KE can be entered by all residents. In principle, therefore, each resident would have the opportunity to work on the draft regulator.
  • a draft regulator ZR according to the invention with a cover, however, the unauthorized handling of the draft regulator ZR can be prevented.
  • the Fig. 2 shows a more detailed representation of the tension controller ZR in a side view.
  • the tension regulator ZR has a housing frame GR, to which inter alia a mounting frame ER, a cover AB and on a pivot bearing SL a control flap RK are attached.
  • the draft regulator ZR In its operational state of installation, the draft regulator ZR is connected to an exhaust pipe, such as in Fig. 1 shown fireplace KA, connected.
  • the draft regulator ZR has the mounting frame ER for installation on the exhaust pipe, which opens into the exhaust pipe and is attached to it.
  • the junction between the exhaust pipe and mounting frame ER is sealed to the outside.
  • the axis AZ of the tension controller ZR is usually orthogonal to the axis of the exhaust pipe in the installed state.
  • a vertically extending secondary air inlet opening NL is provided, which can be closed or opened by the control valve RK as a pressure difference-dependent effective closure element.
  • the control valve RK is pivotally mounted on the pivot bearing SL of the housing frame GR about a pivot axis X. In the Fig. 2 the control valve RK is shown in its closed position.
  • the position of the damper RK is the difference between the pressure on the indoor side, that is, on the side of the secondary air inlet NL facing the exhaust pipe and the pressure on the outside, ie, on the side of the secondary air inlet NL remote from the exhaust pipe indicates, depending.
  • the draft regulator ZR is normally set to the minimum draft requirement of the fireplaces connected to the flue.
  • the tension regulator ZR on an adjustment for adjusting the pivoting behavior of the control valve RK.
  • Such an adjustment element is an in Fig. 2 illustrated counterweight lever GH.
  • the setting of the pivoting behavior is done for example by screwing set weights EC of the counterweight lever GH.
  • the cover AB for covering the control valve RK is attached to the housing frame GR.
  • the cover AB has here such a size and shape that the entire control valve RK is covered together with the counterweight lever GH.
  • the material from which the cover AB is made, is dimensionally stable, z. B. stainless steel.
  • the cover AB here has a box-shaped or pot-shaped configuration, wherein the pot is dimensioned so large that the control valve RK for controlling the pressure difference and for opening the secondary air inlet opening NL is sufficiently far into the pot into pivot.
  • the cup shape of the cover AB ensures good freedom of movement of the control flap RK.
  • Such a box or pot is simple and inexpensive to produce.
  • the cover AB has in the present embodiment on the side to the outside of a door T in the form of a lid, which is removable, if necessary, to open the cover AB and thus easily access from the outside to the control valve RK and the Inside the tension controller ZR to allow.
  • the tension regulator ZR has a lock S with which the lid can be closed.
  • the configuration of the draft regulator ZR should allow air to enter it from the outside.
  • the draft regulator ZR to the surrounding space approximately airtight. It is therefore an air supply line ZL provided over the air from an outside space in the interior of the cover AB and thus can be performed in the tension regulator ZR.
  • the external space does not necessarily have to be the one in which the draft regulator ZR is installed.
  • the supply air line ZL can advantageously be designed so that it leads out into another room or outside.
  • the use of the tension controller ZR according to the invention can be further adapted to certain predetermined conditions. This is especially advantageous when no air is to be withdrawn from the room in which the draft regulator is installed.
  • the door or the cover T can be designed as a type of perforated grid.
  • the cover could have both a perforated lid T and a Supply air line ZL have to supply supply air from the installation space of the Switzerlandreglers and from another room.
  • the draft regulator ZR invention is connected in the basement KE of the building G to the fireplace KA.
