Definitions

  • the invention relates to a shut-off device for an exhaust gas path in a Exhaust system of a fireplace, the exhaust system being a normal one active blower device in the firing phases of the fireplace Generating an overpressure in the exhaust gas path and the shut-off device comprises a shut-off element between the exhaust gas path blocking closed position and an exhaust gas path at least partially releasable opening position is adjustable - and by loading with the overpressure from the closed position towards the open position is adjustable against a closing force.
  • Exhaust systems for overpressure operation can usually use smaller ones Exhaust pipe cross sections or chimney pipe cross sections can be dimensioned. This aspect is often taken up in chimney renovations.
  • a chimney of such an exhaust system for overpressure operation several fireplaces, for example gas fireplaces, can be connected be like this e.g. is described in DE 196 03 615 A1.
  • the fireplaces have a common exhaust gas line Connected fireplace.
  • Each of the flue gas connection lines is included provided a shut-off device between that of the respective fireplace associated blower and the fireplace is positioned.
  • each of the shut-off devices one by means of an electric motor between its closed position and open position adjustable exhaust valve in the exhaust path between fireplace and fireplace on.
  • the exhaust flap in the closed position brought, in which it seals off the exhaust gas path to the atmosphere.
  • the exhaust flap prevents in its closed position an exhaust gas flow from the chimney towards the fireplace.
  • DE 37 15 855 C2 e.g. a bimetal controlled Butterfly valve for an exhaust pipe of a fireplace is disclosed. Bimetal elements are exposed to the temperature of the exhaust gas flow and act as temperature-dependent control elements' for flap elements of the Butterfly valve, so the butterfly valve with increasing temperature the exhaust gas flow presents an increasing opening cross-section.
  • the Bimetallic butterfly valve according to DE 37 15 855 C2 is for one atmospheric chimney system with natural chimney draft. In its closed position, it does not seal the exhaust gas path in question completely.
  • exhaust gas shut-off devices with bimetallic elements or memory alloy elements are e.g. in DE 22 23 517 A and in DE 38 13 170 A1. All of the aforementioned exhaust gas shut-off devices functions according to the principle of forced control the butterfly valve due to the temperature-dependent that is positively coupled with it Actuator bimetallic element or memory alloy element, the Actuator keeps the exhaust flap closed when the temperature is comparatively low. Such thermally positively controlled Exhaust shut-off devices are not very good for use in exhaust systems suitable for overpressure operation.
  • Shut-off devices are for use in exhaust systems for overpressure operation known by a restoring force to the closed position blocked locking elements in the closed position include.
  • the so-called gravity flap is an example called, which is loaded by gravity towards the closed position is.
  • the flue gas flap is Pressurized so that it overcomes gravity in the open position changes.
  • the invention is based, for an exhaust system for pressure operation a shut-off device of the type mentioned provide a shut-off element, which by loading with Overpressure can be transferred from the closed position to the open position, however, the energy consumption of the blower for the overpressure generation is largely minimized.
  • the invention proposes that the Shut-off device a reversible temperature-dependent auxiliary control device for the shut-off element, the auxiliary control device at least one temperature-sensitive auxiliary control element in the exhaust gas path or close to the exhaust gas path, which is set up at a Increasing its temperature within a certain temperature range the closing force opposed continuously or abruptly increasing Apply force to the shut-off element.
  • shut-off device works after Invention similar to a conventional exhaust valve device with Restoring force, such as a gravity flap.
  • a shut-off device according to the invention added the following effect.
  • the auxiliary actuator goes with you setting position corresponding to the closing position of the shut-off element in an adjustment state to exert one of the closing force of the Shutoff counteracting force, where appropriate already in advance by applying gas pressure to the open position transferred shut-off element follows to it in the open position to support.
  • the one applied by the auxiliary control element Supporting force slightly less than the restoring closing force of the shut-off element, so that if the excess pressure in the exhaust gas path disappears, the resultant the closing element from the closing force and the supporting force into the closed position transferred regardless of whether the auxiliary actuator is still open increased temperature or is already back to a lower temperature. Exhaust gas backflow in the exhaust gas path can thus be reliably prevented become. This aspect is particularly important for exhaust systems where the fireplace is occupied by several fireplaces.
  • the principle of the present invention Made use of the fact that the temperature-dependent application of the Shut-off element by the temperature-sensitive auxiliary control element in Opening direction of the shut-off element can be "overridden" by the pressurization.
  • This is according to the preferred embodiment of the invention achieved in that the temperature sensitive Auxiliary actuator is only loosely coupled to the shut-off element, so that the shut-off element in the open position even at a lower temperature can pass if there is an overpressure in the flue gas side of the fire place builds up the shut-off element.
  • the Auxiliary control device at least one bimetallic element as temperature sensitive Auxiliary actuator.
  • this is temperature sensitive Auxiliary control element at least partially with a material Memory effect or shape memory effect formed.
  • the shut-off element is a pivoting butterfly valve in the exhaust gas path.
  • Such Butterfly valve can be single-leaf or have multiple flap elements.
  • auxiliary adjusting element by means of a heating wire or the like. is heated to the in an open position of the shut-off element corresponding setting state to convict.
  • FIGS 1a - 1 c schematically show an embodiment of a Shut-off device according to the invention in different operating states, the shut-off device in a section and in longitudinal section Exhaust pipe of an exhaust system shown for overpressure operation is arranged.
  • the shut-off device has an exhaust flap 3 which in Fig. 1a in their exhaust gas path 9 in the exhaust pipe 5 tightly Closed position is shown. In the example, it is a gravity flap, under the action of gravity in the closed position falls as soon as opposing forces fail.
  • the exhaust pipe 5 is on the one hand at a gas fireplace (not shown) - And on the other hand connected to a chimney pipe (not shown).
  • the side of the fireplace connection is at the bottom in FIGS. 1a-1c, and the side of the chimney pipe connection is in Figures 1a - 1c above.
  • a bimetallic element 7 is used as a temperature-sensitive auxiliary control element Exhaust gas path 9 is provided.
  • One end 11 of the loop bent Bimetallic element 7 is fixed in place on the exhaust pipe 5, whereas the other end 13 of the bimetallic element 7 in Fig. 1a freely on the underside the exhaust flap 3 is.
  • the situation according to Fig. 1a lies e.g. in a Break in operation of the fireplace and the fireplace provided Blower (not shown) for generating excess pressure.
  • the exhaust flap 3 is orthogonal to the exhaust pipe axis pivoting axis 17 upwards into an exhaust gas path 9 releasing open position pivoted, the bimetallic element 7th has hardly changed its state in comparison with FIG. 1a.
  • Such Situation can be in the starting phase of the fireplace and the fireplace side arranged fan.
  • the blower already has an overpressure built in the exhaust path 9, which the exhaust flap 3 on its underside acted upon and transferred to the open position, so that one with flow indicated in the arrows X is forced in the exhaust gas path.
  • the bimetallic element 7 still has no noticeable Experience temperature change.
  • the bimetal element 7 experiences a temperature increase e.g. to 50 ° C and possibly higher and accompanied by a change in shape, as indicated in Fig. 1c.
  • the bimetallic element 7 engages with its free one End 13 above the closed position level indicated at 19 to the Exhaust flap 3, whereby there is a supporting force for the exhaust flap 3 in the offers the open position shown.
  • the exhaust flap 3 is kept open thus no longer just the blower and possibly the thermal buoyancy left. The blower can therefore be operated with less energy to the excess pressure required for exhaust gas discharge maintain.
  • the supporting force of the auxiliary control element 7 at the appropriate temperature is large enough to shut off the shut-off element 3 without fan support hold the open position.
  • the shut-off device be dimensioned such that the supporting force of the auxiliary adjusting element 7 in the heated state alone is not sufficient to close the shut-off element 3 Elimination of the excess pressure in the exhaust gas path 9 in the open position hold. It cannot then happen that after the fireplace and the fan and if a pressure drop occurs Exhaust gas backflow from the chimney towards the fireplace in question takes place through the shut-off device because that is still heated auxiliary actuator 7, the shut-off element 3 only delayed in the Can be closed.
  • the Auxiliary control element 7 is a bimetallic element.
  • element 7 could also have an auxiliary actuator made of a material Memory effect, which occurs at temperatures below a transition temperature has a shape according to FIG. 1a and which one at temperatures above the transition temperature Form state corresponding to FIG. 1c.
  • Memory alloys are known. e.g. NiTi, Cu-Zn-Al, Cu-Al-Ni.
  • the auxiliary actuator 7 can be externally heated and for this purpose an electrical resistance heating wire exhibit.
  • overpressure operation in the context the present application should also generally cover the situation, that on the fire-site side of the relevant shut-off device a higher one There is pressure as the chimney side of the shut-off device. This can e.g. also can be achieved in that the chimney side of the shut-off device suction blower device for a corresponding pressure difference provides.
  • the shut-off element By reheating the auxiliary control element with the external heating during any exhaust gas cooling phases or heating breaks can be according to one Variant of the invention, the shut-off element over the relevant time periods if necessary, be kept in the open position, even if the Overpressure has already largely been reduced.
