Abstract
Description
[0001] The invention relates to a control flap actuation mechanism for a pull regulator, in which a gas passage opening is provided in a frame that separates a first space area from a second space area, the gas permeability of which can be varied by means of a control flap of the pull regulator depending on the pressure difference between the space areas separated by the frame.
[0002] Draft regulators are known in various designs. They are also referred to as draft limiters and secondary air devices. In their typical application, they serve to maintain a relatively constant draft in a chimney or flue during the operation of a connected combustion appliance, or to ensure continuous pressure adjustment in the flue gas system in response to changing operating conditions of the appliance or fluctuating weather conditions such as changes in outside temperature, wind, etc. The pressure adjustment performed by the draft regulator is achieved by mixing secondary air into the flue gas system. Draft regulators are common in the flue gas systems of building heating systems and feature a control flap as a pressure-differential-dependent closing element of a gas passage opening. When such a draft regulator is used in a flue gas system, this gas passage opening typically functions as a secondary air inlet for the flue gas pipe.The control flap is pivotally mounted on a frame surrounding the secondary air inlet opening, allowing it to move between a closed position and various open positions. This enables it to change its position, which determines the opening width of the secondary air inlet (gas passage opening), depending on the pressure difference between the outside pressure and the pressure inside the exhaust pipe. When transitioning to the closed position, the flap may abut the circumferential edge of the secondary air inlet opening with an overlapping section. If the pressure inside the pipe drops relative to the outside pressure, the control flap will move from its closed position to an open position according to the pressure difference. Depending on the opening position of the control flap, the secondary air inlet opening is more or less open, allowing a greater or lesser amount of secondary air to flow into the exhaust pipe.If the pressure in the flue pipe rises again relative to the outside pressure at the damper, the damper can tilt back around its pivot axis into the closed position. The draft regulator is normally set to the minimum draft requirement of the combustion appliance connected to the flue pipe. This is done by adjusting a weight on a lever of a lever mechanism that also moves the damper.
[0003] The known throttle controls have integrated damper actuation mechanisms, which include a pivot bearing for the damper and an adjustment weight lever, e.g., with an adjustment weight carrier threaded rod and an adjustable weight screwed onto it for setting the damper's response to pressure differences. The adjustment weight lever and the damper together form, for example, a two-armed lever that is pivotably mounted about a pivot axis lying in the plane of the frame. Other designs of the adjustment weight lever are also known, e.g., those in which the adjustment weight is fixed to a lever rod or the like by a clamping mechanism.In some known pull-type regulators, the adjusting weight lever projects laterally outwards beyond the edge contour of the frame and furthermore, with its adjusting weight support threaded rod and the adjusting weight, cantilevers relatively far into a space area transverse to the plane of the control flap, so that a relatively large amount of space is required for the entire swivel range of the adjusting weight lever with its adjusting weight support threaded rod and the adjusting weight.
[0004] The known draft regulators are designed in such a way that the control flap actuation mechanism is integrated into the overall construction of the draft regulator and its design is individually adapted to the design of other components of the draft regulator, so that a respective individual control flap actuation mechanism is suitable for each type of draft regulator.
[0005] The invention is based on the objective of providing a control flap actuation mechanism that can be combined with various different pull-control frames or different pull-control housings and can be easily and functionally mounted on them in a predetermined mounting arrangement. A further objective of the invention is to provide a compact pull-control with such a control flap actuation mechanism, which offers flexible application possibilities.
[0006] To solve this problem, a control flap actuating mechanism with the features of claim 1 is proposed under a first aspect of the invention, namely a control flap actuating mechanism for a pull regulator, in which a gas passage opening is provided in a frame that separates a first space area from a second space area, the gas permeability of which can be varied by means of a control flap depending on the pressure difference between the space areas separated by the frame, wherein the control flap actuating mechanism is characterized according to the invention in that it is formed from an assembly that can be mounted as a unit and comprises at least the following components: a bracket fixed to the frame with a pivot bearing defining a pivot axis, a lever mechanism held on the pivot bearing for rotation about the pivot axis with an adjustment weight lever, a ballast weight lever and a control flap lever which is prepared for connection with or connected to the control flap, so that the control flap in the intended installation state of the control flap actuating mechanism in the pull regulator can pivot about the pivot axis between a closed position closing the gas passage opening and a position of maximum release of the gas passage opening, wherein the adjustment weight lever has an adjustment weight which can be set to different adjustment positions and serves to influence the response behavior of the control flap with regard to pressure differences between the space areas separated by the frame, depending on the position of the adjustment weight on the adjustment weight lever.wherein the ballast weight lever includes a ballast weight or is formed by one and is designed to exert a moment on the lever mechanism that tends to load the control flap towards its closed position.
[0007] Depending on the embodiment, the control damper actuation mechanism can already include the control damper on the control damper lever or be simply connected to the control damper lever, for example, by welding. In either case, the control damper actuation mechanism can be dimensioned sufficiently compactly to be mounted as a single assembly unit on the frame of a draft regulator. For this purpose, its components, positioned on either the first or second side of the frame, can be inserted through the gas passage opening to arrange the respective components on both sides of the frame.
[0008] The ballast weight lever with its ballast weight is designed such that, in combination with the adjustment weight lever and its adjustment weight, it can exert sufficient torque on the lever mechanism to achieve the desired preload of the control damper towards its closed position, even with a short lever length. This ensures that the lever does not protrude far into the first area of the lever in any pivot position. The ballast weight, which is preferably a metal block, for example a brass block, can have a relatively large mass compared to the mass of the control damper.
[0009] Preferred embodiments of the control flap actuation mechanism according to claim 1 are specified in dependent claims 2 to 12.
[0010] According to a preferred embodiment of the control damper actuation mechanism, the bracket has a mounting section for fixing the control damper actuation mechanism in a designated arrangement on the frame of the tension regulator and at least one cantilever section projecting from the mounting section into the first spatial region in the designated arrangement of the control damper actuation mechanism on the frame, which has the pivot bearing at a distance from the mounting section, such that the pivot axis extends into the first spatial region at a corresponding distance from the mounting section, wherein the distance between the mounting section and the pivot axis is selected such thatthat in the intended arrangement of the control damper actuation mechanism on the frame, the ballast weight in a basic position associated with the closed position of the control damper is arranged at least predominantly in a spatial area between the frame and a frame-parallel plane containing the pivot axis.
[0011] The bracket is preferably a U-shaped sheet metal part, the base of which forms the mounting section and the arms of which form two cantilever sections that include pivot bearing components for the lever mechanism. According to a very simple embodiment of the bracket, the pivot bearing components in the arms are designed as holes, with the lever mechanism comprising a pivot shaft whose axial ends are pivotably mounted in the holes.
[0012] According to a very simple embodiment of the invention, the adjusting weight lever and the control flap lever are oriented facing away from each other, wherein in the intended arrangement of the control flap actuating mechanism on the frame the lever mechanism is rotatable about the pivot axis by a limited angle of rotation, such that during rotation the adjusting weight lever remains in the first space area – and the control flap lever engages through the gas passage opening into the second space area to move the control flap.
[0013] The ballast weight lever can protrude outwards in relation to the pivot axis between the adjustment weight lever and the control flap lever.
[0014] According to a very simple and cost-effective embodiment of the invention, the lever mechanism comprises a sheet metal bent part which is rotationally fixed to the pivot shaft and has a ballast weight support section connected to the ballast weight, preferably screwed to it, an adjustment weight lever support section immediately adjoining the ballast weight lever and an adjustment flap lever section immediately adjoining the ballast weight lever, forming the control flap lever, wherein the adjustment weight lever support section is angled relative to the ballast weight support section and the control flap lever section is angled relative to the ballast weight lever support section, so that the sheet metal bent part has support sections for the ballast weight, the adjustment weight lever and the control flap oriented in predetermined different directions and forms the control flap lever.
[0015] The adjusting weight lever carrier section and the control flap lever section are preferably formed from a narrow, multiply angled strip-shaped area of the sheet metal bending part, which can only slightly overlap the control flap or the gas passage opening in the intended arrangement of the control flap actuating mechanism on the pull regulator frame on the side of the frame facing the first space area.
[0016] The adjusting weight lever comprises, or is formed from, a threaded rod in a manner known per se, wherein the threaded rod is attached to the adjusting weight lever carrier section projecting outwards from it and carries at least one screw nut screwable along the threaded rod as an adjustable adjusting weight.
[0017] According to a simple variant of the invention, the ballast weight is screwed to the sheet metal bending part with the swivel shaft clamped in between.
[0018] To prevent fluttering movements and the resulting rattling noises of the control damper during rapid changes in the pressure differential between the compartments separated by the tension regulator frame, a damping device can be provided as an element of the control damper actuation mechanism according to one embodiment of the invention. This damping device acts between the lever mechanism and the mounting and has a braking effect on the pivoting movements of the lever mechanism. Suitable, delicate damping devices are available on the market in numerous embodiments.
[0019] The invention further relates to a tension regulator with a frame having a plate-shaped area with a gas passage opening provided therein and separating a first space area from a second space area, with a control flap, preferably in the form of a sheet metal disc, for influencing the gas permeability of the gas passage opening depending on the pressure difference between the space areas separated by the frame, and with a control flap actuating mechanism according to one of the preceding claims, which is attached to the frame in such a way that the pivot bearing and the adjusting weight lever are arranged on the side of the frame adjacent to the first space area, whereas the control flap is provided on the side of the frame adjacent to the second space area.wherein the control damper lever extends from the first space area through the gas passage opening to the control damper and is connected to it, in particular welded. Using the control damper actuating mechanism according to the invention, such a pull regulator can be implemented with simple means and minimal assembly effort.
[0020] Preferably, the frame is designed as a plate with a predetermined outer contour, wherein the control damper actuation mechanism is dimensioned and arranged on the frame such that – viewed from a vertical top-down projection – all components of the control damper actuation mechanism always remain within this outer contour, regardless of the pivot position of the control damper. This frame plate is preferably a plate, preferably a circular plate, with outer dimensions corresponding to the outer dimensions of the cross-section of an exhaust pipe, intake air pipe, or the like. With such a frame and control damper actuation mechanism, the draft regulator can be arranged in different orientations within such a pipe.
[0021] The frame can also be designed as a top cover or insert cover for a pipe stub.
[0022] Preferably, the frame has on its side facing the second space area a seal surrounding the gas passage opening on all sides, preferably a high-temperature glass wool seal, wherein the control flap in its closed position rests against this seal with an overlap area.
[0023] According to a further development of the invention, the control damper can be pivoted about the pivot axis by means of the lever mechanism such that, when the control damper transitions to the position of maximum opening of the gas passage, an edge region of the control damper abuts the side of the frame facing the second space region or a wall connected thereto. Thus, the pivot range of the lever mechanism is limited on the one hand by this stop position of the control damper and on the other hand by the closed position.
[0024] According to a preferred embodiment of the pull regulator according to the invention, the control flap actuation mechanism is connected along an edge section of the gas passage opening outside of it to the frame on its side facing the first space area, so that the pivot axis extends along the edge section at a distance from the frame, wherein the control flap lever, when pivoting the control flap towards the position of maximum release of the gas passage opening, penetrates the gas passage opening in the vicinity of this edge section.

[0038] The control valve actuator mechanism 1 in Fig. 1 features a bracket designed as a U-shaped sheet metal part 3 on, with the U-base having a flat strip-like fastening section 5 forms, from whose lateral ends two boom sections 7 parallel to each other and perpendicular to the fastening section 5 They protrude outwards. At their distal ends, the outrigger sections point 7 each one bearing hole 9 in a joint escape, whereby the camp holes 9 a swivel bearing for a swivel shaft 11 form. The swivel shaft 11their opposite axial ends penetrate the bearing holes 9 , 9 and is protected against axial slippage out of the bearing holes 9 , 9 secured.
[0039] The swivel shaft 11 is between a ballast weight 13 and a sheet metal bent part 15 trapped and together with the ballast weight 13 and the sheet metal bending part 15 around a pivot axis 17 rotatable, which is achieved through the swivel shaft 11 and runs parallel to it.
[0040] The ballast weight 13 In this example, it is formed from a metal block, for example a brass block, which contains the pivot shaft. 11 The contacting area has a cylindrical segment-shaped recess adapted to the swivel shaft shape (at 19 ). The sheet metal bending part 15 features a flat-strip ballast weight carrier section 21on, which extends across the entire width of the ballast weight 13 extends and with ballast weight 13 is screwed together so that the ballast weight 13 , the swivel shaft 11 and the sheet metal bending part 15 are fixed to each other in such a way that they rotate when the swivel shaft is turned 11 around the axis of rotation 17 maintain their relative positions to each other, i.e., together with the swivel shaft 11 around the axis of rotation 17 move.
[0041] The sheet metal bending part 15 indicates a section directly adjacent to the ballast weight carrier 21 subsequent, but relatively angled, adjustment weight lever carrier section 23 as well as one directly attached to the adjustment weight lever carrier section 23 subsequent, still opposite the ballast weight lever carrier section 21in the same direction of angulation and opposite the adjustment weight lever carrier section 23 angled control valve lever section 25 on. In the adjustment weight lever carrier section 23 A through-hole is provided, which is penetrated by an axial end of a threaded rod that holds an adjusting weight lever. 27 forms. The adjusting weight lever 27 is with the adjustment weight lever carrier section 23 firmly screwed in and stands in one of the fastening sections 5 the bracket 3 The lever points outwards in the opposite direction. Near the free axial end, the adjusting weight lever points away from the center. 27 two nuts counter-locked together 31 which form an adjustment weight. The nuts 31 can be adjusted by screwing onto the adjustment weight lever 27 can be adjusted to different positions, so that the adjustment weight lever 27with the adjustable weight 31 Different torque values at the swivel shaft 11 depending on the position of the adjustment weight 31 , 31 on the adjustment weight lever 27 can make it effective. A cap nut 33 secures the setting weights 31 at the axial outer end of the adjusting weight lever 27 against detachment from the adjusting weight lever 27 .
[0042] The sheet metal bending part 15 forms a ballast weight with the attached ballast weight, which forms a ballast weight lever. 13 , the adjusting weight lever 27 with the adjustable weight 31 , 31 and the control valve lever section 25 a connected lever mechanism 4 , which rotates around the pivot axis 17 on the bracket 3 is attached.
[0043] One of the ballast weight 13swivel-mounted locking lever 35 can be pivoted into a locking position in which it engages with a locking lug 37 of a boom 7 collides to cause the lever mechanism to pivot. 4 to prevent movement in one direction. In this way, a movement associated with the control flap actuator mechanism can be prevented. 1 equipped train regulator 2 with control valve in the closed position 39 be locked.
[0044] Fig. 2 shows the control flap actuator mechanism 1 out of Fig. 1 with a control valve arranged thereon as intended 39 This involves a control valve. 39 parallel angled flat mounting area 51 of the control valve lever section 25 at its distal end directly connected to the control valve 39 welded to their front side, with the upper edge of the mounting area between 51of the control valve lever section 25 and the upper edge of the control valve 39 a small gap exists. The elements of the sheet metal bending part 15 , which includes the control flap lever section 25 and the adjustment weight lever carrier section 23 form a continuous narrow strip, which forms the control valve 39 Their front side overlaps only slightly. The ballast weight lever support section 21 of the sheet metal bending part 15 However, it extends over a greater width between the boom sections. 7 , 7 the bracket 3 , so that it is sufficiently stable, the ballast weight 13 to support in such a way that no asymmetrical stresses or deformations occur in the area of the control flap actuation mechanism 1 appear.
[0045] The control valve actuator mechanism 1is, as a whole, connected as a unit to a frame of a train control system. 2 fixable in a suitable mounting arrangement and in the design according to Fig. 2. In the intended assembly arrangement, it can also be combined immediately and ready for operation with a relevant gas pipeline system. Fig. Figure 3 shows an example of a train control system. 2 , wherein the control flap actuator unit 1 with control valve 39 in the intended mounting arrangement on a circular frame plate 41 of the train regulator 2 is fixed. In the frame plate 41 is a gas passage opening 43 trained, who are in the Fig. Situation 3 shown from the control plate 39 in whose closed position it is locked. The fastening section 5 the bracket 3 of the control valve actuation mechanism 1 is directly above the gas passage opening 43on the front 40 the frame plate 41 arranged and thus welded together. The control flap 39 is located on the back 42 the frame plate 41 and is in its closed position according to Fig. 3 with a circumferential overlap area on the back 42 the frame plate 41 on, so that they open the gas passage 43 Completely sealed. On the back of the frame plate 41 is a seal 44 arranged in the form of a layer of glass wool or the like, which has a hole for the gas passage opening 43 The control valve 39 In its closed position, it rests against this seal. 44 on. The seal 44 In addition to its sealing function between the control valve 39 and the gas passage opening 43 a noise reduction function when the control flap 39moves into its closed position and thereby comes into contact with the seal 44 the back 42 the frame plate 41 strikes.
[0046] In the Fig. 4a and Fig. 4b is the train regulator 2 out of Fig. 3 in an installed state on an exhaust pipe 45 depicted in an exhaust system, with the exhaust pipe 45 For the sake of simplicity, only a flat section of wall is shown. 48 is shown. The train regulator 2 is in the area of an opening 46 the exhaust pipe 45 this opening 46 covering the outside of the exhaust pipe 45 placed and separates with its frame 41 a first area 47 , namely the outside space of the exhaust pipe 45 , from a second room area 49 , namely the interior of the exhaust pipe 45 The opening 46 of the wall section 45and the gas passage opening 43 the frame plate 41 of the train regulator 2 aligned with each other, so that the control valve 39 into the interior 49 the exhaust pipe 45 can swing inwards.
[0047] The lever mechanism 4 from the adjusting weight lever 27 with adjustable weight 31 , control flap lever 25 with control valve 39 and ballast weight lever with ballast weight 13 is in relation to the pivot axis 17 balanced so that the control valve 39 according to their response behavior from the closed position Fig. 4a. Open to a position only when a minimum pressure difference occurs between the outside and the outside. 47 and the interior 49 the exhaust pipe 45 transitions. This minimum pressure difference corresponds to the minimum draft requirement of the exhaust system.
[0048] As can be seen in particular from the side view representation according to Fig. 4a, partial image b), the pivot axis can be seen 17 in a frame plate 41 parallel plane 52 , which has a distance A to the frame plate measured perpendicular to it 41 exhibits this. In the closed position of the control valve. 39 The ballast weight is located 13 almost completely, or at least with its main focus, in the space between the plane 51 and the opposite side of the frame plate 41 The ballast weight 13 This means it exerts a torque on the swivel shaft. 11 on, which controls the control valve 39 loaded towards its closing position, whereby the control flap 39 with the control flap lever 25 in the absence of a pressure difference between the spatial areas 47 and 49also pushes towards the closed position. This is counteracted by the adjusting weight lever. 27 with the adjustable weight 31 on the swivel shaft 11 The generated torque is counteracted. This counter-torque can be adjusted by changing the position of the adjusting weight. 31 on the adjustment weight lever 27 can be varied, with the counter-torque increasing with increasing distance of the adjusting weight. 31 from the adjustment weight lever carrier section 23 gets bigger.
[0049] When a pressure difference occurs between the outside and the outside 47 and the interior 49 of the exhaust pipe 45 with the lower pressure inside 49 , the control valve acts 39 Force acting on the control valve in the direction of the opening position 39 one, so that the control flap lever 25 into the swivel shaft 11The applied torque is controlled by the adjusting weight lever. 27 The applied torque is supported. This results in an opening movement of the control valve. 39 , if the ballast weight 13 on the swivel shaft 11 The generated torque is overcome. Fig. 4b is the control valve 39 in their position of maximum release of the gas passage opening 43 shown. It can be in the situation according to Fig. 4b Secondary air from the outside 47 through the gas passage opening 43 easily into the interior of the exhaust pipe 45 flow in to increase the pressure difference between the outside space 47 and interior 49 the exhaust pipe 45 to reduce. As soon as the pressure difference falls below a certain value or even reverses direction, the control valve opens. 39 back to their closed position according to partial image a) Fig. 4a.
[0050] For example, how it looks Fig. As can be clearly seen in section 4b, the control flap lever section extends 25 with the control valve in the open position 39 through the gas passage opening 43 through into the room area 49 (Interior of the exhaust pipe) 45 ), where the control valve 39 with its upper edge when transitioning to the position of maximum release of the gas passage opening 43 in one of the spatial areas 49 facing inner surface 53 the exhaust pipe 45 or possibly the frame plate 41 strikes. The swivel range of the control damper 39 This stop position corresponds, on the one hand, to the position of maximum release of the gas passage opening. 43 and on the other hand by contact with the sealing disc 44 defined according to the closed position.
[0051] Fig. 5a and Fig. 5b shows the control flap actuator mechanism already explained above. 1 , in an arrangement where it is placed directly against a flat wall 41' a gas pipeline 45' (or possibly a room to be ventilated or unventilated) is placed on top of and together with this wall 41' a train regulator 2' forms, which provides pressure equalization between the walls. 41' separate room areas 47' , 49' can cause this, whereby the gas passage opening 43' from one directly in the wall 41' planned opening 46' is formed. A sealing washer. 44' , for example made of a glass wool material, is on the fastening section 3 far side of the wall 41' provided for, so that they open 43' – 46' surrounding its edge and in the closed position of the control valve 39 with an overlap area of the control valve 39can be in contact. Regarding the functioning of the train regulator. 2' according to the Fig. 5a and Fig. 5b and the corresponding control flap actuator mechanism 1 Reference can be made to the explanations above. In the Fig. 5a and Fig. 5b is schematically a friction damping device 64 drawn which between the lever mechanism 4 and the bracket 3 is effective. The friction damping device 64 is on an axial end section of the swivel shaft 11 attached and is part of the control flap actuator mechanism 1 The friction damping device 64 It serves to prevent rapid “fluttering” and “rattling” of the control valve. 39 during rapid changes in pressure difference between the spatial areas 47 , 49 to prevent. Friction damping devices usable within the scope of the present invention 64They are known and available on the market in various designs and small sizes. Naturally, a corresponding friction damping device can also be provided in the other embodiments.

[0054] In the embodiment according to Fig. 7 is the train regulator 2 at the outer end of the pipe stub 58 a T-pipe section 60 an exhaust pipe 45 arranged, with the edge hem 56 of the frame 41 in the pipe stub 58 is arranged and seals against its inner circumference. The control flap actuation mechanism 1 In this arrangement, it is located outside the pipe stub. 58 .
[0055] In the embodiment according to Fig. 8 is the train regulator 2completely within a relevant pipe stub 58 recorded, with the edge seam 56 of the frame 41 on the inner circumference of the pipe stub 58 fits snugly. The embodiment according to Fig. Figure 8 impressively demonstrates that the control flap actuation mechanism 1 so dimensioned and attached to the frame 41 is arranged so that – in a vertical top-down projection according to the viewing direction marked by the arrow X – all components of the control damper actuation mechanism 1 regardless of the pivot position of the control valve 39 always remain within this outer contour, without exceeding the swivel range of the control flap 39 to limit. This is a prerequisite for train controllers to 2 can be fully installed in gas pipelines and functions as intended in such installation situations.
