Definitions

  • the invention relates to an installation set for opening and closing shut-off valves Pipe systems installed underground or in areas that are difficult to access with a square bar reaching to the setting point, which in particular with a Square tube is designed to act as a telescopic rod, and a sleeve tube that in the bell surrounding the connection area of the coupling sleeve and spindle can be inserted is formed and with a sealing in the area of the spindle down and on the slide seated centering and dirt disk is connected, the Dirt disk towards the shut-off valve and an edge cap with sealing washer, which with the square rod is connected, sealing towards the free end of the square rod are arranged and trained.
  • shut-off valves When accessing residential and industrial areas, the frost limits are taken into account Fresh water pipes but also drains and other pipe systems laid in the floor. Both at the junctions of the individual houses as well as in other areas, it is necessary to install shut-off valves, which are then used by the Earth surface must be operated. There are similar problems with pipe systems, which are installed in areas that are difficult to access and where the necessary ones are Sliders and actuators only accessible via longer actuating rods are. With the help of this preferably designed as a telescopic rod the shut-off valves can be opened and closed, these made of square existing telescopic rod is laid in a sleeve tube in order to also with longer standing times to prevent interference from the surrounding soil. In particular In this way, corrosion and. ⁇ .

  • connection between the coupling sleeve and the spindle is made by or through several pins pushed from the side through the coupling sleeve and the spindle in order to create a permanent connection that can also be released again create.
  • the invention is therefore based on the object of being easy to assemble and the shut-off valves on the market with different manufacturers to create adaptable built-in set.
  • the object is achieved according to the invention in that the lower end the square rod-forming coupling sleeve a spacer to be assigned to the bell has a pulling of the square rod from the spindle of the shut-off valve is designed to prevent and arranged and that serving as a stop Dirt disk works together.
  • the dirt disk is advantageous used as an adapter with which an end point or stop results.
  • this Stop can be given a distance between the bell neck and sleeve, which is then is filled in via the spacer mentioned.
  • one almost backlash-free connection is created after the telescopic rod is attached to the spindle. Because the distance between the bell neck and dome is from manufacturer to manufacturer is different, must be different or customizable accordingly Spacers are used, which are the subject of further claims.
  • the telescopic rod is placed on the spindle, the Bell with the spacer pushed onto the dirt disk and then the earth condensed around the bell, one advantageously achieves a connection that at least the Pinning is equivalent. Because of their much easier assembly, this is Hole in the ground necessary for attaching the installation set is much smaller and narrower, which in turn reduces overall manufacturing costs contributes significantly.
  • the interior is advantageously sealed up and down.
  • the Bell at the insertion end for the sleeve tube limiting the insertion path of the sleeve tube Has ring projection, which as well as the upper edge of the dome sleeve Abutment for the spacer is used.
  • a limitation is advantageous in this way created for the spacer to be inserted or inserted, whereby the ring projection as mentioned at the same time as an insertion limitation for the sleeve tube serves. Since the ring projection is injected or manufactured together with the bell the additional effort is practically irrelevant. An exact fixation of the Spacers are easily and appropriately achieved.
  • the spacer can have different shapes and dimensions. Appropriate training
  • the spacer is the one in which it is used as a double-shell, the dimensions of the manufacturer adapted sized sleeve is formed. Since you have the measure or the distance Knows beforehand due to the known dimensions of the shut-off valve, the spacer specified accordingly and even by the manufacturer of the installation set already be built in, so that after pushing on or plugging on the desired one backlash-free connection between bell neck and sleeve is guaranteed. It is advantageous that subsequent installation is also possible. Because this spacer is divided into two, the two half-shells can be easily installed.
  • a training that can be easily adapted to the respective valve type of the spacer is that which holds the upper cylinder part, also the sleeve tube the bell is equipped with internal ribs that act as spacers.
  • the ribs can be sprayed with it, so that it can be used again at the place of use finished unit is available, but depending on the valve type or cut-off valve type is tailored. Subsequent changes are not possible; however, there is an advantageously play-free connection available.
  • the ribs have a much lower weight, than with the solid material sleeve according to the previously described designs.
  • a particularly light and simple design of the spacer is that at which the square bar has a disc in the area of the ring projection, which Ring projection is arranged below.
  • Washer in the square for the respective manufacturer-specific distance or Weld the square tube and then slide the bell open from above during assembly, so that it then settles precisely in the area where this is for the backlash-free Connection is necessary.
  • Another training is that in which the spacer is one with latches equipped spacer sleeve is formed with the ring projection and a the centering ring associated with the upper edge of the coupling sleeve is designed to cooperate is. It is understood that the spacer sleeve on the square rod or Square tube slid on or connected to it in some other way. It can't move up or down, using the telescopic tube with the centering ring is attached to the respective valve type. The square bar or telescopic bar is then pushed down until the coupling sleeve sits on the spindle. It is advantageous that due to the grid this training can be used for practically all valve types is, but without any possibility, the connection after its establishment to solve again.
  • the spacers are also possible to assign these parts of the bell serving as spacers, for which the The invention provides that the cylinder part of the bell is equipped with internal ribs is and that in addition, the dirt disk on this cylindrical Distance rings are assigned. As mentioned earlier, the ribs are also included Production of the bell sprayed. The spacer rings that act as spacers are then placed on the adapter and the bell is the last thing to put on it so that a connection is then reached, that with the pinning can be equated.

Accordingly, with this version it is possible to the square bar and the bell inside the locking profile in both directions to be moved in order to enable optimal installation.
  • the Spacer sleeve connected to the square tube the individual locking grooves in more or less uniform distance must be provided, so as close as possible To enable grids or to make adjustments. It is advantageous that such a built-in set can be used universally for all valve types, whereby however, the production is somewhat complicated due to the special design.
  • the locking profile as loose over the Locking grooves and locking sleeve that can be moved in the cylinder part with internal locking rings is formed and that a spring ring insertable between the cylinder part and locking sleeve is provided.

  • this bracket is a relatively simple component is that can be manufactured and assembled with little effort, being a the base part comprising the square rod and at least two with outer end lugs has equipped detent springs and the dirt disk with the outer end lugs Correspondingly trained slot openings is equipped. This is the possibility given to slide the clip onto the dome sleeve from above and to connect effectively with the dirt disc, and then, as mentioned, also the To push the bell over it.
  • the invention provides that the bell is equipped with holes which are designed to receive a clip serving as a spacer, wherein the clasp is arranged on the upper edge of the coupling sleeve. After the bell has been pushed on, pushing this clasp in becomes the necessary one Fixation brought about, just as in the previously described embodiment the disadvantage here is that again an exact adaptation to the respective manufacturer is required. To prevent the clasp from falling out, it is advantageous to if the holes and the insertion ends of the clasp correspond to each other are trained.
  • the invention contemplates that the approach one under the thickness of the locking ring lying opening cross-section is formed and that the Bell distributed over the circumference with the cylinder part has several approaches with correspondingly designed and ordered spring feet of the locking ring work together. This requires a certain amount of force to be applied to the locking ring to press into the recess, by friction and a certain Form-fit the locking ring is then so tight that it only requires appropriate force, d. H. can be resolved on purpose. Three approaches are advantageous provided so that the cross sections even if as prescribed require a certain amount of effort, but this is not too great because of the friction only three feather feet must be overcome. Because the spring feet on the one hand and the Approaches that are distributed over the circumference, on the other hand, have a corresponding design assembly is not made more difficult, but rather even easier because less Force must be applied as mentioned.
