Abstract

Die Erfindung betrifft einen Hydrant, insbesondere Unterflurhydrant, mit einem Mantelrohr, mit einem damit verbundenen Ventilgehäuse, das an ein Rohrnetz, umfassend erste Rohre, anschließbar ist und in dem ein Hauptventilkörper anordbar sind, wobei der Hauptventilkörper mit einem ersten Ventilsitz zusammenwirkt und mittels einer im Mantelrohr geführten Spindel über eine Innengarnitur betätigbar ist, und mit einer Entwässerungsvorrichtung, die eine Buchse zwischen einerseits dem Ventilgehäuse und/oder dem Mantelrohr und andererseits dem Hauptventilkörper, die den ersten Ventilsitz bereitstellt und zumindest eine Ausnehmung, die zwischen der Buchse und dem Ventilgehäuse und/oder dem Mantelrohr zumindest eine Verteilungskammer festlegt, und zumindest eine Bohrung, durch die Durchflussmedium des Hydranten aus dem Mantelrohr und oberhalb des Hauptventilkörpers bei geschlossenem Hauptventil zur Verteilungskammer hindurchtritt, während solche ein Durchfluss bei geöffnetem Hauptventil unterbrochen ist, aufweist, und zumindest eine Entwässerungsbohrung, die eine Bohrung durch das Ventilgehäuse und/oder eine Bohrung durch das Mantelrohr umfasst, um die Verteilungskammer mit dem Äußeren des Hydranten zu verbinden, umfasst.

Figure 00000001
The invention relates to a hydrant, in particular underfloor hydrant, with a jacket tube, with a valve housing connected thereto, which can be connected to a pipe network, comprising first pipes, and in which a main valve body can be arranged, wherein the main valve body cooperates with a first valve seat and by means of a in the Spindle guided spindle is operable via an inner fitting, and with a dewatering device having a sleeve between on the one hand the valve housing and / or the jacket tube and on the other hand the main valve body, which provides the first valve seat and at least one recess which between the sleeve and the valve housing and / or at least one distribution chamber defines the jacket tube, and at least one bore, through the flow medium of the hydrant from the jacket tube and above the main valve body with the main valve is closed to the distribution chamber, while such a flow with the Haupv and at least one drainage bore comprising a bore through the valve housing and / or a bore through the jacket tube to connect the distribution chamber to the exterior of the hydrant.
