Definitions

  • the invention relates to a device for emptying and filling radiators with heating fluid according to the preamble of claim 1.
  • Such a device is known from DE-89 01 447 U1.
  • the closure body can be adjusted from its sealed closed position against a return spring in the open position. The closing movement and the sealing is therefore only dependent on the functioning of this spring. If this is corroded by the ingress of moisture or damaged for other reasons, or possibly broken or tilted during its uncontrollable return movement in the closed position, a secure seal against the escape of heating fluid cannot be guaranteed.
  • the invention is therefore based on the object to provide a device of the type mentioned, in which the advantage is retained that emptying and filling a single radiator is possible without an overhanging tap being permanently installed on it, but with the adjustment in the closing direction - independently of a return spring - should be able to be carried out reliably.
  • the above-mentioned device is characterized in that the closure body for its adjustment in the axial direction for opening and closing is acted upon by a projection or connecting piece which has an external thread which fits into an internal thread of the sealing plug or of the connecting part, and that the projection or socket is connected to the closure body, the actuating element and / or the connecting part. It is therefore sufficient to insert and screw in the connecting part in order to adjust the closure body itself in the axial direction with the aid of a threaded part. An adjustment via a thread results in a reliable and easily adjustable adjustment movement.
  • the projection or socket can protrude from the closure body on its side facing away from the inside of the radiator in the position of use and protrude into an internal longitudinal cavity of the closure plug and have an external thread which fits an internal thread arranged in the closure plug or in the connecting part, and by the rotation of the projection or Nozzle and its axial adjustment so the closure body itself can be adjusted in the axial direction away from its sealing seat in the open position and in the opposite direction of rotation in the opposite axial direction. Since the projection or socket engages the closure body on its side facing away from the interior of the radiator, the closure body can thus be opened deeper into the radiator and thereby moved away from its sealing seat, so that it is not only in the closed position due to its normal fastening but also is also held by the fluid pressure.
  • An embodiment is particularly advantageous in which the connecting piece with an external thread is connected in one piece to the closure body and has a coupling opening into which a counter-coupling of the actuating element of the connecting part which is effective in the direction of rotation fits. If the connecting part is thus attached, the actuating element with its counter-coupling enters the coupling opening of the connecting piece and thus the closure body, so that after the liquid-tight fastening of the connecting part, the closure body is also rotated by rotating the actuating element, which due to the external thread belonging to it on its connecting piece leads to its axial adjustment initially in the open position and in the closed position when actuated in reverse.
  • the thread for the closure body is arranged in the opposite direction to that of the closure plug is, so that an actuating element acting on the closure body from the outside of the closure plug can be rotated in an opposite direction of rotation when the closure plug is released when the closure body is closed. In this way it can be ruled out that by closing the sealing plug, the sealing plug screwed into the heating element may be accidentally loosened or released with a certain tightening force.
  • the thread of the sealing plug is a common right-hand thread
  • the thread of the sealing body can be a left-hand thread, which has the additional advantage that the actuation element is actuated in the direction in which other water fittings also open in the usual way and closing are rotated, that is to say a counterclockwise rotation causes the opening and a clockwise rotation causes the closure body to be closed, and the closure plug is also tightened with its thread in a clockwise direction.
  • the connecting part is formed in two or more parts and a mechanically releasable connection, in particular an external thread, for fastening, and has a sealing stop if the connecting part has an inner longitudinal cavity extending in the axial direction and if the actuating element with the mating coupling is arranged and mounted in the interior of this inner longitudinal cavity for releasable engagement in the corresponding coupling opening of the closure body.
  • the connecting part can first be securely attached and thereby also sealed, before the actuating element is then rotated to open the closure body.
  • the connecting thread of the connecting part matches the thread for the adjustment of the closure body, that is to say it corresponds to the thread on the socket of the closure body, and if an internal thread is provided in the closure plug in the axial direction, from one side of which forth the projection or socket with the external thread of the closure body and from the other side, if necessary, the connecting part is screwed in.
  • the internal thread in the sealing plug can be manufactured continuously in one operation and can then accommodate the connecting piece with an external thread, that is to say the closure body, and from the other side, if necessary, the connecting part from its two ends.
  • the sealing body is designed as a valve plate which carries a sealing ring or is in contact with a sealing ring in the closed position
  • the Sealing plug has an inner stop for the tight contact of the valve plate of the closure body.
  • Such a valve plate can be made very flat and flat, in particular on its side facing the interior of the radiator, so it does not protrude at least in the closed position from the inside end face of the sealing plug.
  • valve plate in particular if this valve plate is pulled into its closed position by means of a thread and which thereby reaches its sealing seat with a simultaneous rotary movement, so that any smaller solid bodies which could prevent a tight sealing seat, can be eliminated at least by turning back and forth several times.
  • the closure body has an effective stop in the axial direction for limiting its opening path, which interacts with a counter stop in or on the stopper. This simplifies operation, especially when opening, because the user does not necessarily have to be careful not to inadvertently adjust the closure body too far in the axial direction and thereby remove it from its holder. Something like this is prevented by the abovementioned stop.
  • a structurally particularly simple solution can consist in the fact that the stop on the closure body is a radial protrusion, in particular on its connecting piece or projection, and the counter-stop on the closure plug is a crimping of the passage opening.
  • a flanging can be carried out at the end of the through opening facing the sealing body, in particular in the valve outlet, so that when this projection is screwed back out of the sealing plug, i.e. later in the opening direction of the sealing body, the axial adjustment is limited in that the stop can only be adjusted up to this crimp.
  • the closure plug can have a profile in the region of its internal thread, in particular at least one axial groove for the passage of liquid when the closure body is open.
  • annular groove On the end face of the sealing plug facing the interior of the heating element in the position of use, an annular groove can be provided, the outer groove wall of which as an annular circumferential sealing seat for the opposite seat of the valve plate of the sealing element and its inner wall is interrupted by the grooves and is flanged in particular in the radial direction as a counterstop to limit the axial adjustment of the closure body.
  • the actuating element has a profile, preferably an outer profile for a tool and / or a handwheel or the like.
  • the valve can be rotated with the aid of a tool after the rotary coupling has been produced with the closure body, or it can in particular also be actuated by hand when closing, after which the last fixed rotary movement for the tight closure seat is then carried out the tool can be carried out.
  • the further opening movement can be carried out by hand.
  • the actuating element can be a threadless spindle for an only rotatable closure body, which on its front end facing the interior of the heating element has a counter-coupling which is effective in the direction of rotation for releasable engagement in a coupling opening of the closure body.
  • an actuating element can be inserted in the axial direction until its counter-clutch engages in the coupling opening of the closure body, after which a rotary movement is sufficient to bring the closure body first into the open position and then back into the closed position.
  • the connecting piece for a hose can be arranged on the connecting part laterally or radially starting from the connecting part and the connecting part can be formed in two parts, the wall carrying this connecting piece being rotatably mounted with respect to the sealing part. This allows the connector to be attached and then the hose connector to be brought into one position that is particularly convenient for draining or filling. It is thus avoided that the hose connection may then be directed directly towards the building wall by screwing on the connecting part.
  • a closure fitting with multiple functions as a device for closing a radiator, but which, if necessary, also enables the radiator to be flushed, filled or emptied, so that, for example, a separate radiator can be filled or emptied and no longer an entire heating system must be emptied for this purpose.
  • the sealing plug with the sealing body remains on the radiator, while the connecting part with the actuating element used for flushing, filling and emptying only has to be connected when necessary.
  • a device designated as a whole with 1 serves to enable the emptying, rinsing and filling of radiators.
  • the device 1 includes a closure part, which is designed as a plug 3, which has an external thread 4, with which it can be permanently screwed into a suitable internal thread at the corresponding opening on the radiator or on a pipeline connected to a radiator.
  • the sealing plug 3 has an openable sealing body 5 which closes a channel or line part 6 for the heating liquid which passes through the sealing plug or releases it in a manner to be described when it is emptied or filled.
  • the sealing plug 3 has an inner cavity 7 and a seat 8, which is designed differently depending on the embodiment, for the sealing body 5 arranged wholly or partly in its interior. All the exemplary embodiments have in common that this sealing body 5 is arranged coaxially with the sealing plug 3, that is to say the same central axis Has.
  • the closure body 5 is adjustable for opening and closing in the axial direction relative to the plug 3.
  • sealing plug 3 with the sealing body 5 is located on the radiator or a corresponding supply line.
  • a cover cap closing off its inner cavity 7 can also be provided on the outside of the sealing plug 3.
  • a connecting part 10 which detachably engages the closure body 5 or the closure plug 3 and which has an actuating element 11 which can be moved relative to it and thus also relative to the closure plug 3 and an inner cavity 12 has, through which the actuating element 11 can reach.
  • This inner cavity 12 is in liquid-conducting connection after opening the closure body 5 with the aid of the actuating element 11 with the channel or line part 6 of the closure plug 3, so that a hose connection can then be provided in different ways.
  • the device 1 can be used to be able to empty a radiator, possibly independently of a central heating system and without completely emptying it, it can be shut off from the rest of the heating system and then emptied via the device 1.
  • the connecting part 10 with the actuating element 11 can be attached to the one provided with a closure body 5, after which the closure element 5 can be adjusted axially or in the direction of rotation by means of the actuating element 11.
  • the closure body 5 is acted upon for its adjustment in the axial direction for opening and closing by a projection or connecting piece 13 which has an external thread 14 which fits into an internal thread 15 of the closure plug 3.
  • This projection or socket 13 is connected to the closure body 5. A rotation of the projection or socket 13 causes an axial adjustment at the same time due to the threaded connection, so that the closure body 5 is moved axially accordingly.
  • the projection or socket 13 protrudes from the closure body 5 on its side facing away from the interior of the radiator or a pipe in the position of use, is fixed, in particular even integrally connected to the closure body 5, projects into the inner cavity 7 of the closure plug 3 and has the external thread 14, which fits to the internal thread 15 located in the sealing plug 3. It is obvious that the rotation of the projection or socket 13, due to the threaded connection, causes its axial adjustment and thus the axial adjustment of the closure body 5 in the axial direction initially from the closed position away from its sealing seat 8 to the open position and with the opposite direction of rotation in the closed position.
  • the socket 13 with external thread 14 in these embodiments has a coupling opening 16 into which a counter-coupling 17 of the actuating element 11 of the connecting part 10 which is effective in the direction of rotation fits. This ensures that after coupling the device 1 with the connecting part 10 and the actuating element 11, a simple rotation is sufficient to adjust the closure body 5 in the open and closed positions.
  • the connector 13 is integrally connected to the closure body 5.
  • the cross section of the coupling opening 16 is a hexagon socket, in which a corresponding external hexagon then fits as a counter-coupling 17.
  • the rotary handle 18 can have an outer and / or inner profile for a corresponding one Have tools or be a handwheel.
  • the thread for the closure body 5 is expediently designed in the opposite direction to that of the closure plug 3, so that an actuating element 11 engaging from the outside of the closure plug 3 on the closure body 5 can be rotated in an opposite direction of rotation when the closure body 5 is closed is.
  • an actuating element 11 engaging from the outside of the closure plug 3 on the closure body 5 can be rotated in an opposite direction of rotation when the closure body 5 is closed is.
  • the closure plug 3 is not accidentally loosened.
  • the connecting part 10 is formed in two parts. It can be seen that one part has a mechanically releasable connection for fastening, in this exemplary embodiment an external thread 19 and additionally a sealing stop 20.
  • the connecting part 10 has an axial longitudinal cavity in the interior of which the actuating element 11 is arranged, which has approximately a spindle shape so that it penetrates practically the entire axial length of the connecting part 10 and also protrudes on both sides. In the interior, it projects above all with the counter-coupling 17, while on the outside the rotary handle 18 projects beyond the connecting part 10. This ensures that when connecting the connecting part 10 to which the counter-coupling 17 also comes into releasable engagement in the corresponding coupling opening 16 of the closure body 5.
  • the connecting thread 19 of the connecting part 10 matches the internal thread 15 for the adjustment of the closure body 5, so that a plug 3 is inserted in the closure
  • continuous internal thread 15 can be provided, from which the projection or socket 13 with its external thread 14 and from the other side, if necessary, the connecting part 10 can be screwed, as shown in Figures 1 and 2 .

  • the closure body 5 is designed as a valve plate which carries a sealing ring 21. But it would also be conceivable that the sealing ring 21 would be provided on the seat 8 for this valve plate, which then acts on this sealing ring 21 and then bears against this sealing ring 21 in the closed position.

  • the closure body 5 has, for this axial limitation of its opening path, a stop 22 which is effective in the axial direction and which interacts with a counter stop 23 in the interior of the closure plug 3.
  • the stop 22 is advantageously formed by a backward rotation of the external thread 14 of the socket 13.
  • the stop 22 is a radial projection on the closure body 5, specifically at its socket or projection 13, while the counter-stop 23 on the plug 3 is in this case a crimping of the passage opening or the line part 6 of this plug 3.
