Definitions

  • the invention relates to a pipe connection part with a main part with a water shut-off element having an adjusting element between an inlet side and an outlet side, a threaded part on the inlet side for screwing into a pipe connection point, an outlet-side thread and a closure cap that can be screwed onto this.
  • connection points for sanitary objects are provided with so-called building plugs in order to protect the connection points against the ingress of contaminants during plastering and tiling.
  • building plugs should also ensure a certain clearance between the pipe connection and the tile edge after their removal, which is necessary for unimpeded installation of any extensions that may be necessary after tiling or plastering, in order to avoid re-tiling of tiles, plaster or mortar.
  • the object of the invention is to design the pipe connection part in such a way that the adjusting element is simultaneously protected against contamination and against displacement without additional parts.
  • the pipe connection part 1 comprises a main part 2 and a sealing cap 3.
  • the main part 2 comprises a tubular entry section with a threaded part 4 at its entrance for screwing into a pipe connection point.
  • a water shut-off device 5 is provided at a distance from the threaded part in the tubular section.
  • the water shut-off device is designed as a ball valve with associated valve seats and seals.
  • the valve has an outward adjusting screw 6, which serves as an adjusting element for the water shut-off element 5.
  • the outlet 7 is connected to the water shut-off element 5 with an external thread 8.
  • the tubular section and the section comprising the water shut-off device are made of different materials and are firmly connected to one another by gluing or welding.
  • the main part 2 has on the side of the adjusting screw 6 facing away from the thread 8 a wall section 9 extending perpendicular to the axis of the thread 8.
  • the outside diameter of this wall section is so large; that its edge protrudes outward beyond the set screw.
  • the closure cap 3 has a cap base 10, an adjoining first cylindrical section 11 and a second cylindrical section 13 connected thereto via an intermediate piece 12.
  • the first cylindrical section 11 has on its inside an internal thread adapted to the thread 8 in such a way that the cap can be screwed onto the thread 8 up to the cap base.
  • the second cylindrical section is designed so that it is the adjusting screw when screwed on be 6 completely covers.
  • the outside diameter is chosen equal to the outside diameter of the wall section 9.
  • a sealing element 15 is provided at the bottom of the cap base 10.
  • the axial dimensions of the first and second cylinder sections and the intermediate piece are chosen so that in the screwed-on state the free end of the outlet 7 is firmly closed by the sealing element 15 and the cap base and the free edge of the second cylindrical section is just against the wall section 9 and thus hermetically seals the interior of the closure cap surrounding the set screw.
  • the pipe connection part is closed by the sealing element 15 and the cap base in addition to the closure by the water shut-off element.
  • the setting element is protected against soiling or unintentional adjustment.
  • the closure cap 3 has on the outside of the cap base a screw element 16 which, when the closure cap is unscrewed, can be placed on the adjusting screw for actuating it.
