Description

Device for throttling the heat output of radiators The invention relates to a device for throttling the

Heat output of radiators when cool outside air enters the room to be heated by opening a window or door.

It is known to provide heating systems for rooms used by people with a control system. The control system is usually designed in such a way that the radiator power is controlled roughly as a function of temperature or weather. The radiators in the individual rooms can be provided with separate thermostatic valves, through which an individual regulation of the heat output of each individual radiator is possible. The disadvantage of this decentralized regulation of the heat output of radiators is that, due to the system, when the rooms are ventilated by opening windows or doors, the thermostatic valve responds due to the incoming cooler fresh air and increases the heat output of the radiator. Particularly in the case of radiators arranged under windows, the heated air which is now increasingly rising on the radiator by convection can escape from the window, so that increased energy consumption arises.

In order to avoid these disadvantages, it has already been proposed to provide a further sensor in a thermostatically controlled radiator valve which reacts much more quickly than the actual thermostat sensor.

When cold air occurs, this additional sensor bridges the thermostat, as a result of which the valve is closed. It is also known to associate with each radiator valve a special electrical control circuit ^', which is connected with contacts that elements of the Verschluß¬, are like windows or doors, angordnet. When such a contact responds, a heating device provided on the radiator thermostat is actuated, which thus increases the height of the thermostat sensor re pretends room temperature than actually exists. As a result, the thermostatic valve closes and the supply of heating medium is interrupted. The known devices have the disadvantage that they have a relatively complicated structure and do not permit the further use of thermostatic valves installed on the radiators. Rather, they have to be replaced when retrofitting with the known devices.

The object of the invention is to provide a device for automatically throttling the heat output of radiators when opening windows or doors, which can also be retrofitted to existing thermostatic valve systems. This device is also intended to have an attachment for thermostatic valves, the valve rod of which is accessible through slot-shaped openings formed in the surface of the thermostatic attachment facing the valve body, without the need to increase the depth of the thermostatic valve by installing intermediate pieces. According to the invention, the object is achieved by a sensor which can be brought into active connection with the window or door leaf for receiving the closed or open position of the window or door leaf as a measured value and which is connected to an actuator of a radiator throttle device by means of a measured value transmission element. The sensor, the measured value transmission element and the actuator can be designed as a hydraulic, pneumatic, electrical or mechanical element.

According to a special feature of the invention, the attachment is formed by a holder which is connected to the radiator valve by means of a clamping piece, the free end portion of which is introduced into the thermostat attachment by an opening in the surface facing the radiator valve and one by means of a bridle cable , a hydraulic or pneumatic actuator or the like. Actuable, pivotable about an axis of rotation spring pressure has a loaded lever, one lever arm of which rests on the flange of a cap which is mounted on the valve stem.

Further refinements of the invention are described in the subclaims and are explained in more detail below with reference to the exemplary embodiments illustrated in the drawings. It shows

The device 10 shown in FIG. 1 for throttling the heat output of a radiator essentially consists of a memory 3 and a radiator throttle device 11 which are connected to one another by means of a connecting line 7. The store 3 is formed as a hollow body made of an elastic, deformable material and is arranged in a window or door frame 2. The memory 3 is located at the window. or door frame 2, which is no longer covered by the window or door leaf 1 when the window or door leaf 1 is opened. The memory 3 is preferably let into the window or door frame 2. The connecting line 7 is also incorporated in the area of the window or door frame 2.

The radiator valve device 11 is designed as a radiator valve 16 which can be installed on radiators 33. The radiator valve 16 has a hydraulic actuator 17 which is connected to the accumulator 3. The hydraulic actuator 17 is designed as a bellows 18, which is mounted in a recess 19 of the valve body attachment 20. One base plate 21 of the bellows 18 is supported on the valve body 22, while rend the other bottom plate 23 is connected to the valve rod 24. At a distance from the base plate 23 there is a pressure plate 26, which is also connected to the valve rod 24. A spring 25 acts on the pressure plate 26 and is supported on a stop 27 of the valve body attachment 20. A bore 29 is provided in the jacket 28 of the valve body attachment 20. The bellows 18 is fastened to the lower end section of the through hole 29, for example by means of a compression fitting. At the outer end portion of the through hole 29 there is a screw connection 30, which can also be designed as a compression screw connection and by means of which the connecting line 7 is connected to the through hole 29 and thus to the bellows 18.

When the window or door leaf 1 is closed, the memory 3 is pressed together and the hydraulic fluid located therein has been pressed into the bellows 18. As a result, the bellows 18 has expanded against the pressure of the spring 17 and raised the valve rod 24 by means of the pressure plate 0 23, so that the valve cone

24a was pulled out of the valve seat 16. A heating fluid can now be applied to the radiator. If the window or door leaf 1 is opened, the spring 27 relaxes and in doing so presses the valve cone 24a back into the valve seat 16a via the pressure plate 26. As a result of this displacement process, the base plate 23 of the bellows 18 is also displaced and hydraulic fluid in this is pressed through the bore 29 into the reservoir 3. Due to the closed heating ⁰ body valve to the radiator is not performed more energy zu¬. When the window and door leaf 1 is closed, the fluid in the reservoir 3 is pressed out of it again, as a result of which the bellows 18 expands again against the pressure of the spring 25.

5 E _S is also possible to arrange a thermostat attachment 32 on the end section of the valve body attachment 20 facing away from the radiator 16. This thermostat attachment 32 regardless of the Heizdorsdorsseleinrichtung 11 with the valve rod 24 in operative connection. The function of the device 10 is not impaired by the actuation of the thermostat attachment 32.

In Fig. 2, a memory 4 is shown, which is also embedded in a door or window frame 2. The memory 4 consists of a rod-shaped elastic hollow body 5, which is designed as a rectangular frame and is provided with a connecting means for connection to the connecting line 7. The memory 4 can be in the door and

Window frame 2 trained circumferential grooves for sealing profiles are used and then simultaneously serves as a sealing frame 5. To increase the seal, it is possible to provide 5 sealing lips 6 on a side surface of the rod-shaped hollow body.

As shown in FIGS. 3 to 5, the radiator throttle device 12, 13, 14 is designed as a lamella grid 34, 35 covering the radiator 33 on the room side; 37; 40 trained. The heater 33 according to FIG. 3 is clad with horizontal fins 34 on one side surface and the upper surface. When the window is closed, the lamellae are in a position arranged perpendicular to the radiator in order not to impair the heat emission of the radiator 33 by radiation or convection. When a door or window sash 2 is opened, the slats 34 are pivoted in the same direction about their longitudinal axis by 90, so that the heat is interrupted by convection or radiation. The lamellae 36 of the lamella lattice 34, 35 are actuated by means of a special actuator 9. This can be designed as a hydraulic cylinder 41, as shown in FIG. 6, the piston rod of which is connected to a rod drive 42. The rod drive 42 shown in FIG. 6 is designed as a rack and pinion drive 44 which is actuated by the piston rod of the cylinder 41 via lever 43. It is also possible to change the piston rod of the To connect cylinder 41 with a lever mechanism that enables pivoting of the slats 36 directly.

In the louvre grille 37 shown in FIG. 4, the heating element 33 is covered on the room side by vertical louvers 38. The vertical slats 38 can likewise be rotated through 90 ° by means of an actuator. The actuator can be designed like that shown in FIG. 6.

In Fig. 5, the radiator 33 is designed as an underfloor convector, which is mounted in a shaft 45. The shaft 45 is covered with a roller grille 46. Unter¬ half of the roller grate 46 is located the disk grating 40, the slats 39 of the pivotally by actuation of a ^{'Stellglie¬.} ,

The hydraulic sensor shown in FIG. 7 is designed as a hydraulic motor with a hydraulic cylinder 51. The cylinder 51 is connected on the pressure side to the connecting line 7 and has a piston 52 which can be actuated by means of an articulated drive 61 which can be controlled by the window or door leaf 1. The cylinder 51 is arranged on a base plate 50a, which is fastened to the window or door frame 2. The piston rod 52a of the piston 52 is guided through an opening 53 with a guide 54 through the cylinder cover 51b. A pressure plate 56 is anchored to the end section of the piston rod 52a and is supported on the cylinder cover 51b by means of a compression spring 57. A guide plunger 59 is arranged in the center on the other side of the pressure plate 56 and is telescopically displaceable in a guide bush 60 which is fastened to a pressure plate 68. Between the pressure plate 68 and the pressure plate 56, a damping spring 58 is arranged, which is also designed as a compression spring. The articulated piece 62 of the articulated drive 61 is pivotally attached to the pressure plate 68 in a bearing 64, the other piece of which Steering piece 63 is pivotally mounted in a bearing 65 located on a holding piece 67. The holding piece 67 is connected to the base plate 50a. When the window is closed, the stop 66, which is fastened to the window or door leaf 1, presses on the articulated bearing 61a, so that a pressure is exerted on the pressure plate 56 via the pressure plate 68 and the damping spring 58, which pushes the piston 52 into the cylinder 51 pushes. When the hydraulic motor 50 is used as a measurement sensor, the actuator 8 can be designed like the actuator shown in FIG. 5. In particular to reduce the overall height of the radiator nozzle device 11, however, it is also possible to design the actuator 8 in such a way that the spring 25 is arranged in the area of the bellows 18, for example.

It is also possible to design the actuators of the radiator throttle devices 11, 12, 13, 14 by an electric motor and to connect them to an opening contact arranged on the window or door frame 2. When the window or door leaf 1 is opened, a pulse is sent to a control device of the electromotive drive of the radiator throttle device 11, 12, 13, 14 via the opening contact, as a result of which the latter is actuated by a motor. Such a design is particularly advantageous if the connecting line 7 would become too long for the hydraulic system to function properly for local reasons.

8 shows a device according to the invention for throttling the heat output of radiators, in which a solenoid valve 70 is used. The valve rod 24 is connected to a magnetic plate 72 which is supported on a compression spring 73. The magnet plate 72 can be brought into operative connection with a magnet 71 arranged in the valve housing. The magnet 71 is by means of a control line 75 controllable by a control relay 76, which is fastened in the window or door frame 2. The control relay 76 has a switch contact 77, which is in operative connection with the window or door leaf 1 closed with a stop plate 78 located thereon. In this case the magnet 71 is without current, so that the valve rod 24 with the valve is pressed out of the valve opening by means of the pressure spring 73. In this position, the radiator throttle device operates by means of the thermostat attachment 32 like a conventional thermostatically controlled radiator valve. The connection between the thermostat attachment 32 and the valve rod 24, which is connected to the magnet plate 72, is made via an adjusting screw 74, which is arranged between the actuator of the thermostat attachment 32 and the magnet plate 72. When the window or door leaf 1 is opened, the magnet 71 is energized and the magnet plate 72 is attracted. As a result, the valve is closed, bypassing the function of the thermostat attachment 32.

9 is a possible mechanical design of the

Device 80 for throttling the heat output of radiators shown. An angle lever 89 which can be actuated by the window or door leaf 1 is attached to the window or door frame 2 as a sensor. One lever section of the angle lever 89 is operatively connected to the window or door leaf 1, while the other lever is connected to a control lever 86 by means of a bouden cable 88. The control lever 86 designed as a two-sided lever is connected to an axially displaceable valve adapter 81 which is arranged between the radiator valve and the thermostat attachment 32. The valve adapter 81 is supported on the radiator valve by means of a compression spring 87. The valve rod 24 is connected to the valve adapter 81. On the surface of the valve adapter 81 facing away from the valve rod 24, a guide pin 82 is formed which, in a bush-like section, corresponds to: *? Ι ^ ^WI * 85 of the thermostat attachment 32 is displaceable. In this socket-like section 85 of the thermostat attachment 32, the adjusting screw 84 is also arranged, by means of which the thermostat attachment 32 is connected to the valve adapter 81. When the window or door sash is open, the control lever 86 is pivoted by means of the spring 90 via the bouquet pull 88 and the valve rod 24 is raised by means of the valve adapter 81, so that the valve is opened and can only be regulated by the thermostat attachment 32. If the window or door leaf 1 is closed, there is a pivoting of the angle lever 89 and thus also via the Boudenzug 88 of the control lever 86, whereby the valve cone Ven valve 81 is pressed into the valve seat. The spring 90 as well as the damping spring 58 (FIG. 7) for absorbing pressure surges when the window or door leaf 1 is swung into the window or door frame 2.

10a to 10c show how a thermostatic valve consisting of a thermostatic attachment 32 and a radiator valve 16 by installing a valve body attachment 20a, 20b, 20c designed as an intermediate piece, optionally with a hydraulic device 10a, an electrical device 70a and a mechanical device for throttling the heat output of a radiator is connected. The valve body attachment 20a, 20b, 20c is fastened by means of screws 92 to a flange 91 which is connected to the radiator valve 16.

In the embodiment shown in FIG. 10a, an annular hose 18a is connected in the recess 19a of the valve body attachment 20a and is connected to the connecting line 7. A pressure plate 26a is located on the ring hose 18a, on which a pressure spring 25a is supported against the housing of the valve body attachment 20a. The valve cone 24a is connected by means of a tension spring 93 to the bearing flange 94 of the valve body 22, in which one

__ - 1 1 -

Opening is formed through which the valve rod 24 is guided. The valve rod 24 is connected to the actuator 32a of the thermostat attachment 32 by means of an adapter 100. The adapter 100 consists of a bearing piece 101, which is pushed onto the valve rod 24, and a plunger 102 arranged on the bearing piece 101, the free end section of which is designed as a threaded section 103. The threaded section 103 can be screwed into the threaded bore 32b of the actuator 32a and is used for the fine adjustment of the device 10a and for adapting the thermostat attachment 32 to the valve body attachment 20a and the radiator valve 16. When the ring hose 18a is pressurized with the window closed or When the door is closed, the pressure plate 26a is pressed upwards against the pressure effect of the compression spring 25a and the bearing piece 101 is thus relieved. As a result, the actuator 32a of the thermostat attachment is connected directly to the valve rod 24 via the adapter 100 and only has to overcome the force of the tension spring 93. The position of the valve cone 24a is therefore exclusively dependent on the function of the thermostat attachment 32. If pressure relief of the ring hose 18a occurs when the window or door is open, the compression spring 25a presses the pressure plate 26a down until it comes to rest on the bearing piece 101 and presses it downward. As a result, the valve rod 24 and thus also the valve cone 24a is also pressed in the direction of the valve seat until the valve cone 24a lies sealingly thereon.

In the electrical device 70a shown in FIG. 10b, a bearing piece 101a is formed on the underside of the magnetic plate 72. In this bearing piece 101a, the valve rod 24 is mounted, the valve cone 24a of which is connected to the bearing flange 94 of the radiator valve 16 by means of a tension spring 93. A plunger 102a is formed on the upper side of the magnetic plate 72 and _ 1 2 _ ^{~ "}

has a threaded portion 103 on the side. This threaded portion 103 is, as described in Fig. 10a, screwed into a threaded bore 32b of the actuator 32a of the thermostat attachment 32. The threaded section 103 also serves for the fine adjustment and adaptation of the device 70a to the existing radiator valve 16. As long as the magnetic plate 72 is not attracted to the magnet 71, the position of the valve cone 24a can thus be determined exclusively by the actuator 32a of the thermostat attachment 32 can be controlled. Only when current is applied to the magnet 71 via the control line 75 is the magnetic plate 72 attracted and thus the valve cone 24a pressed onto the valve seat of the radiator valve 16.

10c shows a mechanical device 80a, in which a valve adapter 81a is also actuated by means of a bouquet pull 88 via an angle lever 89 as a function of the position of the window or door leaf 1 relative to the window or door frame 2. The valve adapter 81a has a two-armed lever 105, one leg 105a of which can be supported on the bearing piece 101 of the adapter 100. The end section of the leg 105a preferably has a spherical curvature in order to prevent the edge of the leg 105a from edging on the bearing piece 101. The other leg 105b is connected to the bouden cable and is supported by a compression spring 107 on a flange 104 which is formed on the valve body attachment 20c. In this valve body attachment 20c there is an opening in which the two-armed lever 105 is mounted about an axis of rotation 106. When the window or door leaf 1 is closed, one leg of the angle lever 89 is pressed against the window or door frame 2, as a result of which the bouquet pull is tightened and thus the leg 105a does not rest on the bearing piece 101. As a result, there is a direct operative connection between the actuator 32a of the thermostat attachment 32 and the valve rod 24

O the valve cone 24a guaranteed by the adapter 100. When the window or door leaf 1 is opened, the compression spring 107 acts against the end section of the leg 105b of the two-armed lever 105 and presses this leg 105b upward. As a result, the leg 105a is lowered and comes to rest on the bearing piece 101, whereby it is pressed downward. As a result, the valve rod 24 is also pressed down against the force of the tension spring 93 until the valve cone 24a comes to bear sealingly on the valve seat.

In Fig. 11, a radiator valve 16 is shown schematically, on which a thermostat attachment 32 is pushed. On the radiator valve 16, an outer flange 112 is formed, over which a resilient gill sleeve 112a is pushed, which in the area of the surface 110 of the

Thermostat 32 is connected to this. The radiator valve 16 has a central guide bush in which the valve rod 24 is axially displaceably mounted. The actuator 32a of the thermostat attachment is arranged coaxially with the valve rod 24. On the end portion of the valve rod 24, a cap 121 is inserted. The top plate 121 consists of a bushing 123, on the end of which a closed top surface 123a is formed. An annular flange 122 is formed on the other end section. The free end section of the valve rod 24 is inserted into the recess 124 in the bush 123. The actuator 32a can be brought into abutment on the other side of the head surface 123a.

The hat plate 121 can be brought into operative connection with an actuator of the attachment 115. The attachment 115 consists of a holder 116, which preferably has a U-shaped cross section. The free end section 120 of the holder 116 is inserted into the thermostat attachment 32 through openings 111 formed in the surface 110 of the thermostat attachment 32. On the side webs 116b, 116c O PI of the holder 116, a two-armed lever 117 is mounted about an axis of rotation 118. One lever arm 117b is fork-shaped and rests on the flange 122 of the top plate 121. The other lever arm 117a is connected to a tension spring 119 and is operatively connected to a Boudenzug 88. The bouquet pull 88 is actuated when a window or door leaf is closed or opened, as a result of which the lever 117 pivots. If the window or door leaf is opened, the lever 117 presses the cap in the direction of the radiator valve 16, as a result of which the valve rod 24 is pushed into the radiator valve 16 until the radiator valve 16 closes.

If the radiator valve 16 is designed in such a way that the valve is closed to interrupt the flow of heating medium by pushing the valve rod 24 outwards, while pushing the valve rod 24 into the radiator valve 16 opens it, it is only necessary instead the hat washer 121 to use a rigid washer which can be slid movably onto the valve rod 24, but which can be brought into abutment on the underside of the actuator 32a by moving the lever 11-7b which is under the washer. In such an embodiment of the radiator valve 16, the flow of heating medium when a window or door leaf is opened can be prevented by lifting the actuator 32a by means of the lever 117 by means of the valve rod 24 and displacing the radiator valve 6 when it is closed.

12 shows an attachment 115a with a power amplifier. This consists of a hydraulic cylinder which is fastened to the outer end section 120a of the holder 116. The piston of the hydraulic cylinder 128 can by means of a bouquet pull 88 or a hydraulic or pneumatic actuating element depending on the

O Opening of a window or door leaf. The piston rod 129 of the piston is connected to the lever arm 117a of the lever 117 by means of a joint 130. By means of the hydraulic cylinder 128 it is thus possible, even in the case of unfavorable lever ratios of the levers 117a, 117b to one another, to bring about a sufficient lever force which is necessary for acting on the top washer 121 or a washer. In the event that a washer has to act against the actuator 32a, it is necessary to design the spring 119 as a tension spring. Furthermore, the force must be applied to the lever 117a in such a way that when a hat plate 121 is used, the lever 117b moves towards the radiator valve 16 when a window or door leaf is opened, while when a washer is used the lever 117b moves when a window is opened ¬ must remove the door or wing from the radiator valve 16.

To fasten the attachment 115, 115a, in the region of the end section 120a of the holder 116, retaining webs 125 are formed on the side webs 116b, 116c, in which elongate openings 126 are formed. Through these openings 126, a clamping piece 127 is guided, which can be clamped on the gill sleeve 112a of the thermostat attachment 32 (FIGS. 11 and 12).

It is also possible to form a holding bracket 131 on the holder 116, which is in operative connection with the side webs 116b, 116c and / or the central web 116a and whose leg 134 can be brought into contact with the gland sleeve 112a (FIG. 13) . By means of the clamping piece 127 guided over the leg 134, the holder 116 is clamped to the clamping sleeve 112a and thus to the radiator valve 16.

By connecting the other leg 135 of the bracket 131 to the side webs 116b, 116c and possibly the

OU ^Ό Ϊ - 1 6 -

Adequate strength is ensured in the central web 116a. The transverse web 132 of the leg 135 formed in the area of the cross-sectional area of the holder 116 has an opening 133 through which, for example, the bouden cable 88 or a line for a hydraulic or pneumatic actuator can be guided.

The attachment 115b shown in FIG. 14 is used for the mostat attachments 32 which are spaced from the radiator valve 16 by means of a support member 139, openings 111 being formed in the support member 139. Through one of these openings 111, the lever arm 117b of the lever 117 can be guided to rest on a cap 121. In the attachment 115b, the lever 117 is likewise rotatably mounted on a holder 116 by means of an axis of rotation 118, the lever arm 117a being connected to the base cable 88. A web 137, which has an opening 138 and is arranged perpendicular to the side webs 116b, 116c, is formed on the central web 116a. The Boudenzug 88 is guided through this opening 138. A pressure spring 119a is arranged between the web 137 and the lever arm 117a. A slot-like opening 126 is formed in each of the side webs 116b, 116c, through which the clamping piece 127 is guided. The clamp 127 can e.g. be designed like a clamp and connects the holder 116 to the radiator valve 16 by means of a clamping action.

In the described embodiments of thermostatic valves, the attachments 115, 115a, 115b thus make it possible to adapt them so that the radiator valve 16 can be closed immediately when a window or door leaf is suddenly opened, without the structural depth of the thermostatic valve concerned being enlarged by intermediate pieces or the like becomes. This avoids that the retrofit thermostat 32 compared to the

O __. _

tical level of the room-side radiator surface or protrudes from under covers and easily damaged by bumping or the like. The assembly of the attachment 116b is particularly simple because in this case the lever 117 only has to be inserted through openings already present on the thermostatic valve. In order to prevent a possible tilting of the lever 117b on the flange 122 of the disk 121, it is advantageous to form the fork-shaped end section of the lever arm 117b spherically.
