Definitions

  • the present invention relates to a main hydrant valve comprising a main valve body and a main valve seat, wherein the main valve body is formed by means of a drive device from at least one open position in at least one closed position and vice versa brought.
  • the main valve body acts on the main valve seat in the closed position so that the hydrant main valve seals a component of this hydrant with respect to a hydrant inlet.
  • Hydrants have been known for a long time and in many different versions. They serve primarily as valves for water extraction from a public (often municipal) or private supply network and supply, for example, the fire department with extinguishing water.
  • FIG. 1 An example of an overground hydrant is off CH 675 139 A5 known and here as a vertical section in FIG. 1 displayed.
  • This Automatflurhydrant is composed of an inlet pipe 1, a riser 2 and a mounted on the riser 2 essay pipe 3 together.
  • the inlet pipe 1 is shown here with an inlet bend 13.
  • the inlet pipe 1 can also be designed as a straight piece of pipe (dashed lines, see arrow).
  • a seat 4 of a main end valve 5 is arranged, whose valve body 6 is mounted on a projecting into the riser pipe 2 valve rod 7 with a substantially vertical axis 14.
  • the spindle extension 17 has an axis 27 and protrudes through a, attached to the upper end of the top tube 3 housing cover 18 and has at the end of a Betuschistsvierkant 19.
  • a protective cover base 20 is fixed to which a protective cover upper part 21 is rotatably mounted.
  • two side valves 22,23 are installed, the spindles 24,25 each with a Betreli whysvierkant 26 protrude into the space formed by the protective cover parts 20,21 and sealed by seals.
  • These side valves 22,23 each have a valve port 28,28 ', which are closed by a screw 29. Through a bore 30, the ventilation of the interior 31 of the hydrant with open side valve 22,23 and thereby emptying via the drain valve 33 is made possible.
  • a closure pin 32 is fixed, on which a key with a square hole (not shown) can be placed to open and close the protective cover shell 21.
  • Hydrants with such a hydrant main valve have been installed for many years in or on Swiss water distribution networks and have proven themselves.
  • the double barrier comprises a main closure valve and an additional shut-off valve 41.
  • This hydrant comprises an inlet pipe 1, a bulbous extension 42, a main valve housing 43 and a riser formed as a casing pipe 2.
  • a telescopic tube 44 is arranged vertically movable, so that the height of the hydrant 40 of the current installation depth can be adjusted (see also DE 100 28 655 A1 ).
  • the valve body 6 of the main end valve 5 is also attached to a valve rod 7 with a substantially vertical axis 14 and formed vertically movable.

  • a hydrant with flat or conical sealing main valve known.
  • the valve seat acted upon from below (ie, from the pressure side of the water supply) by the main valve body is annular.
  • the valve seat is screwed from the top to stop and has an upper circumferential seal, which seals the valve seat against a between the riser of the hydrant and the main valve housing arranged drainage ring (with drainage opening).
  • One of the vertical guide ribs of the main valve body closes the drain hole as soon as the main valve is opened.
  • a lower circumferential seal seals the valve seat from the main valve body.
  • valve seat can be fitted with a corresponding flange on the inlet bend (in this case on the main valve body) or held on the riser, so that in one case the riser from the combination inlet bend / dewatering ring / valve seat or in another case the inlet bend of the combination riser / drainage ring / valve seat can be separated without the respective combinations must be dismantled.
  • an improvement (simplification) of the service work on defective hydrants can already be detected here, in every repair case the inlet bend must be disconnected from the supply network (eg by means of a slide) and at least part of the hydrant dismantled.
  • valve seat is annular, is screwed into abutment in the inlet bend and has in the case of GB 26,561 a flat gasket on.
  • annular valve seat (with integrated drainage opening) is screwed directly into the upper end of the inlet bend (ie the main valve body).

  • an annular insert is placed over the original (old, defective) valve seat in the inlet bend (pressed or screwed in).
  • the annular insert is sealed by means of a seal against the inlet bend.
  • the main valve body is replaced and replaced by a cylindrical or radial sealing repair valve body whose sealing surfaces are adapted to the annular insert.
  • an improvement (simplification) of the service work on defective hydrants can be determined, nevertheless, in every repair case, the main valve body must be replaced.
