Definitions

  • the invention relates to a control valve, in particular a thermostatically controlled valve, with a rotary handle for setting the temperature and a spring-loaded, releasable locking device for blocking the rotary movement of the rotary handle in a predetermined rotary position, which, due to a spring-engaging, approximately radially movable lock between the rotary handle and a non-rotatable valve component and a radially displaceable trigger for the lock.
  • a control valve has become known in the form of a thermostatically controlled mixing valve, for example from FR-A-2 169 566. It is used to mix cold and hot water.
  • the triggerable locking device ensures that when this valve is opened the mixed water temperature cannot initially rise above a certain maximum value in order to avoid scalding. If a temperature of the mixed water exceeding this predetermined value is desired, the lock must first be released manually, i. H. a different mixing ratio of the two flows is only possible after the blocking device has been triggered beforehand.
  • valves with triggerable latching devices have also become known, the aim of which is also to prevent scalding or, in the case of designs which are not used to mix two media streams, to limit the amount flowing through, for example a gas stream, to a predetermined value. All these valves, however, have in common that after the locking device has been triggered, a further rotation by 360 ° is possible and the valve spindle can make two or more revolutions.
  • valve spindle can make a maximum of a single revolution, so that this valve can also be used as a thermostatically controlled valve. Even in such cases, it would be desirable to limit the flow rate at a certain opening of the valve and to allow a larger flow rate only after a blocking device has been triggered.
  • the object of the invention is therefore to design a control valve of the type mentioned in such a way that it can also be used for domestic heating systems, the releasable locking device being designed to be particularly simple but also very expedient.
  • control valve is designed in accordance with the preamble of claim 1 in accordance with the characterizing part of this claim.
  • the setting range is limited to at most one revolution of the spindle or of the rotary handle, so that when using a thermostatic attachment or the like, it is always possible to reliably assign the quantity flowing through to the scale attached in the circumferential direction.
  • the rotary movement can be blocked after a predetermined partial rotation of the spindle, for example after a 180 ° rotation, which is why higher flow values, as required, can only be achieved if the lock is triggered beforehand.
  • this blocking position is assigned a temperature value of 20'C
  • this control valve ensures that the user does not unnecessarily overheat the room equipped with such a control valve, but can only reach a higher temperature value in a very targeted manner, namely by releasing the locking device. If you consider that, for example, an increase in the room temperature of 1 ° C leads to an additional energy consumption of about 6 percent, you can easily measure the value and advantage of this control valve. Overheating of the room is prevented with this control valve even if, as is often the case, it is placed in an unfavorable position, for example, behind a curtain, so that the setting scale cannot be seen or cannot be seen easily. Until the blocking position is reached, there is usually no risk of wasting energy, and when adjusting a higher temperature, it is inevitable that you take the time to set the rotary knob exactly to the desired value.
  • the locking device is of a very simple design, easy to assemble and, if necessary, also to repair. The release of the lock is also easy and quick to do in a known manner. Furthermore, the special design of this locking device, due to its special design, offers the possibility of providing at least one further preferred blocking position.
  • a further development of the invention is characterized in that the resilient, tongue-like stop member is formed in one piece with the ring. This leads to a simple, robust and inexpensive design.
  • a strip-shaped extension is attached to the latter, in particular molded on, which overlaps a bead-like bulge of the ring.
  • this construction can also be used in a very advantageous manner in that the bead-like bulge of the open ring formed from resilient metal in the predetermined rotary point tion of the twist grip opposite an inner support member of the twist grip and in this way a perfect safeguard against the open ring jumping off when the locking device is triggered.
  • the inner support member is at a very short distance from the bead-like bulge, which corresponds to the usual play between rotatable parts that should not touch during normal rotation.
  • the stop for the stop member is formed by a radial elevation of the rotary handle, which at the same time is a stop effective in both directions of rotation for the bulge of the ring which represents a double stop member.
  • the extent to which the reverse rotation stop is used depends on the design of the valve in detail.
  • the tongue-like stop member bears an outwardly angled nose which interacts directly with the stop. It ensures that when turning further after the locking device has been triggered, the friction on the inside of the rotary member is minimal. On the other hand, it ensures secure and precise locking.
  • Another embodiment of the invention is characterized in that the stop for the stop member is formed by the inner wall surface of an eye receiving the trigger of the rotary handle and the opposite wall surface of the eye serves as a further stop for the nose when rotating in the closing direction.
  • the stop for the stop member is formed by the inner wall surface of an eye receiving the trigger of the rotary handle and the opposite wall surface of the eye serves as a further stop for the nose when rotating in the closing direction.
  • a further preferred embodiment of the invention is characterized in that in the opening and closing direction offset from the eye of the rotary handle on the inner circumference of the rotary handle, two locking notches are provided, into which the nose of the stop member optionally engages in one or the other rotary end position of the rotary handle.
  • the amount of their mutual distance depends on the position of the valve spindle in the closed position on the one hand and the maximum possible degree of opening of the valve on the other.
  • the trigger is directed towards the free end of the tongue-like stop member or, in the embodiment according to claim 7, has two oppositely inclined run-up bevels for this free end. This means that the free end of the stop link can be passed over the trigger in both directions of rotation and the automatic engagement when turning back and forth is no problem.
  • the exemplary embodiment is a thermostatically controlled radiator valve, the rotary handle 1 of which is provided with a scale 2, which cooperates with a marking 3 of an undrotatable component 4 of the valve.
  • the component 4 does not necessarily have to be manufactured separately; rather, it can also be an integrally formed housing connector on which the rotary handle 1 is mounted directly. If the middle of the scale, for example the number "three", is assigned to marker 3, then a room temperature of 20 ° C is maintained, for example. If it is to be warmer in the room, marking 3 must assign the "four” or "five” to the scale, while the scale values "one" and "two" correspond to lower room temperatures.
  • the rotary handle 1 can be rotated without restriction up to the predetermined mark, as in any conventional radiator valve. In this way you can set the preferred room temperature up to preferably 20 ° C very quickly. This requires no special care and no scale reading.
  • the preferred scale number that is to say the “three” in the exemplary embodiment, is expediently located on a trigger 5, the meaning of which is explained below.
  • FIGS. 2 and 3 Various embodiments of the locking device 6 for the preferred setting value can be seen in FIGS. 2 and 3.
  • Each consists of a non-rotatably connected to the non-rotatable component 4, housing-fixed ring 7 and the non-rotatably connected movable stop 8.
  • One of the parts 7, 8 has a radial elevation 38 or recess 10, which with a stop 9 of the other part cooperates.
  • a radial recess 10 is provided on an eye 11 of the rotary handle 1, into which the inner end of the trigger 5 projects.
  • the stop 9 is formed by the hook-like free end of a stop element 12 shaped in the manner of a leaf spring, in particular made in one piece with the ring 7.
  • the ring 7 can for example be made of plastic.
  • a rotation of the handle 1 in the direction of arrow 13 is only possible if the trigger is previously actuated in the direction of arrow 14.
  • the rotary handle 1 can be turned further, and the higher scale values (FIG. 1) or temperatures are thereby obtained.
  • This further turning can be ended by suitable means, for example by a notch 15 of the rotary handle 1, which forms a second stop 16 and into which the hook-like end of the stop member 12 a further rotary movement preferably occurs by about 90 °.
  • the arrow-shaped inner end 17 of the trigger 5 is moved past, starting from the preferred setting of the thermostatic valve shown in FIG. 2, the stop member 12 being inserted into the recess 10 of the ring 7. and exits from it.
  • This rotary movement ends when the stop member 9 has arrived on the other side of the radial recess, i. H. strikes the stop 18 for the rectangular inner end of the trigger 5.
  • the turning handle can be turned back against the arrow 13 when the trigger 5 is actuated again.
  • a further notch 19 of the rotary handle 1 then finally ends this reverse rotation.
  • the ring can be held in a form-fitting manner or non-rotatably on the valve component 4 using known fastening means.
  • FIG. 3 The embodiment of FIG. 3 is similar in FIG. 2, but there the ring 7 is designed as an open ring and made from a steel band, as is used for leaf springs. This ring 7 can be held perpendicular to the image plane by molded-on tabs 20. To prevent rotation, a strip-shaped extension 21 of the non-rotatable valve component 4 is used, which is enclosed by a bead-like bulge 22 of the ring 7. In the blocking position of the locking device 6 is opposite this bead-like bulge 22, a support member 23 which is integrally formed on the inner surface of the handle wall. It prevents a radial deflection of the spring in the direction of arrow 24, which could take place when the trigger 5 is actuated.
  • the stop member 12 is formed by one free end of the ring 7.
  • a surface corresponding to the stop 18 of FIG. 2 serving as a guide surface is not provided in this variant, which is why the rotary handle 1 can be turned back here by an angle of 90 ° and more without further notice.
  • the inner end of the trigger 5 is in turn rectangular, and also a run-up slope 25 is provided for the stop member 9.
  • a second inclined surface 26, which points obliquely upward in FIG. 3, makes assembly easier.
  • a molded-on strip 29 at the inner end of the guide 28, which extends in FIG. 3 perpendicular to the image plane. It interacts with a stop surface 30 of the trigger 5.
  • the trigger 5 is secured against pulling out in the opposite direction of the arrow 27 in a known manner.
