    The invention relates to a built-in set with a protective tube according to the preamble of the claim
    1.
    Installation sets for shut-off valves for water, sewage or gas pipes are installed in the most common cases below the frost line in the ground and serve to connect residential and industrial properties with the main pipes for water, sewage and gas so that they can be switched off. In order to enable the shut-off valve to be closed at any time, the spindle of the shut-off valve with attached coupling sleeve is connected via a key rod, e.g. a square tube, connected, the upper end of which is provided with a further nut for placing a key and is arranged slightly below the surface, for example under a street surface. Fittings arranged in the ground and their connections to the surface of the earth are exposed to environmental influences, in particular moisture or possibly under the streets of road salt. As a result, over the years or decades of the service life of a shut-off valve, it is particularly exposed to corrosion, especially in the damp environment and from above, through road salt. To at least the upper area of the spindle with the square of the valve and the linkage, e.g. To protect the key rod, it is known to surround the key rod with a one-part or multi-part protective tube, to which a so-called bell is attached at the lower end, which includes the coupling sleeve on the shut-off valve and is axially immovably fastened thereon. The protective tube enables the surface to be removed at any time, e.g. of the street surface, after removing a street cover, actuate the shut-off valve.
    Since even with such a shut-off valve corrosion or possibly a fatigue break despite sheathing with a protective tube can not be avoided over all the years or decades, the soil around the shut-off valve must be excavated / dredged in the event of such an event, to the damage to fix. This work is time-consuming and costly, and there is also a latent risk that the supply line to a property cannot be disconnected from the main line quickly enough in an emergency.
    An object of the present invention is now to develop a protective tube such that in the event of a defect at the coupling point between the key rod and the shut-off valve in the protective tube, access from above is maintained and the defective part can be replaced.
    This object is achieved by an installation set with a protective tube according to the features of claim 1. Advantageous embodiments of the installation set are described in the dependent claims.
    The inventive design of the protective tube, in particular the lower part of the protective tube on the bell attached to it, makes it possible that when the coupling sleeve is damaged at the lower end of the key rod, the key rod together with the coupling sleeve can be extended from the protective tube and in this way by the Protection tube through the replacement of the parts without digging is possible. This accessibility is created by a predetermined breaking area in the lower area of the protective tube / bell, which enables the key rod and the coupling sleeve to be pulled out. The predetermined breaking area can be broken up by a tensile force acting upward on the key rod, and the stop on the protective tube that was previously axially restrained can thus be overcome. The key bar can be pulled out in a simple manner using suitable tools. In the exemplary embodiments, the predetermined breaking area lies in a funnel-shaped design of the protective tube / bell, which promotes the insertion of the key rod into the protective tube and at the same time forms the axial stop against the lifting of the key tube from the coupling sleeve. The predetermined breaking area can take place through a circumferential perforation arranged on a line or a linear circumferential material taper, e.g. in the form of a constriction in the wall of the funnel-shaped area. In a further embodiment, not shown, the funnel-shaped area is connected to the protective tube by a breakable adhesive bond.
    The invention will be explained in more detail with the aid of an illustrated embodiment. Show it:
    Fig. 1 an installation set on a shut-off valve, e.g. a slider, protected in the upper area by a street cap (standard installation),
    1a is a perspective view of the one-piece (rigid) installation set,
    2 is an exploded view of FIG. 1 with elements assembled,
    3 shows a telescopic installation set with a protective tube cut open in the lower section,
    Fig. 4 is an enlarged view of the portion designated by A in Fig. 3 of a first embodiment
    Fig. 5 is an enlarged view of the section designated by A in Fig. 3 of a second embodiment.
    With reference numeral 1, a shut-off valve, in the present example a slide is shown, which is installed in a water, sewage or gas line 3. About a coupling sleeve 23, which is placed on the spindle 15 of the slide 1, a protective tube is designated with reference numeral 9 as part of the installation set. The protective tube 9 may be rigid in one part or, as shown in FIGS. 1 and 2, in two parts, it being possible for the two parts, namely the upper protective tube 9b and the lower protective tube 9a, to be telescopically displaceable. Above the upper end of the protective tube 9 there is a tubular shaft 11 with a road cover 13 which, when installed, comes to lie in the plane of a street, a path or a square. The casing of the street cap 11 can be constructed from two telescopically interlocking sections in order to position the street cover 13 exactly in the plane of the floor surface.
    In Fig. 2, the individual elements of the protective tube 9 are made visible. The square end of a spindle 15 protrudes from the upper end of the slide upper part 5 of the shut-off valve 1 and actuates the closure element (not shown in the shut-off valve 1). The closure element can be designed to be vertically displaceable or pivotable about the vertical axis or rotatable as a ball valve around the vertical axis of the spindle 15. At the upper end of the upper protective tube 9b, the end of a key rod 19 forming a square 17 is visible at the top. The key rod 19 runs inside the protective tube 9, at the lower end of which a receptacle is formed on the slide upper part 5. At the lower end of the key rod 19, which is formed, for example, by a profile tube which is rectangular in cross section, there is a coupling sleeve 23 for the square at the end of the spindle 15. In FIGS. 4 and 5 it can be seen that a lower funnel-shaped tube 9a from above downward and inward converging region 25 is formed. This comprises two sections, namely the funnel-shaped section 25 and preferably also a cylindrical section 27 adjoining it at the bottom. The funnel-shaped section 25 serves, on the one hand, to insert the key rod 19 through the protective tubes 9a and 9b essentially in the center of the protective tubes 9a and 9b to hold and on the other hand, the funnel-shaped section 25 carries the cylindrical section 27, the lower edge 27 'of which is designed to form an axial stop for the upper edge 23' of the coupling sleeve 23.
    The coupling sleeve 23 is, for example, immovably held with a screw 29 penetrating the wall of the coupling sleeve 23 or a correspondingly designed bolt in a bore 31 in the key rod 19 and forms an axially acting connection with the key rod 19.
    On the one hand, the coupling sleeve 23 is used to transmit the torque from the key rod 19 to the square at the end of the spindle 15 of the shut-off valve 1. On the other hand, the coupling sleeve 23 has the purpose that the spindle rod 19 cannot be moved axially upwards and thus the torque transmission Shut-off valve 1 would be interrupted.
    It can also be seen in FIGS. 4 and 5 that the bell 9c in the area of the coupling sleeve 23 has a larger inside diameter Di than the outside diameter D2 of the upper slide part 5. The inner diameter Di is slightly larger than the outer diameter D2 at the upper end of the upper slide part 5, at which point the spindle 15 is guided (see also FIG. 2). Furthermore, a number of axially parallel slots 33 can be formed at the lower end of the bell 9c, through which an expansion takes place when the installation set 9 is placed on the slide upper part 5 of the shut-off valve 1, which is slightly conical at this point, and thereby the bell 9c is held positively on the slide 1.
    4, a perforation is formed in the funnel-shaped section 25, which consists of a plurality of recesses or holes 35, which are located on a circumferential line. These holes 35 form a predetermined breaking area, from which the lower area of the funnel-shaped section can break off when the key rod 19 with the coupling sleeve 23 is pulled upward with a corresponding force. In the second embodiment of the invention according to FIG. 5, a linear perforation 37 of the wall of the funnel-shaped section 25 takes the place of a linear perforation.
    As an alternative to the holes 35 as a perforation line or the constriction 37, in a further embodiment of the invention the funnel-shaped section 25 could be glued or fastened to the inner wall of the bell 9c in such a way that it acts by a force that acts from the bottom up detaches from the inner wall of the bell 9c. This embodiment is not shown.
