Description
Den Gegenstand der Erfindung betrifft ein Wasserventil mit gesteuertem Rückschlagventil.The object of the invention relates to a water valve with controlled Check valve.
Abb. i zeigt das Ventil im Längsschnitt nach der Linie A-B der Abb. 2, Abb. 2 eine Seitenansicht des Ventils und Abb. 3 einen Querschnitt nach der Linie C-D der Abb. 2.Fig. I shows the valve in a longitudinal section along the line A-B in Fig. 2, Fig. 2 is a side view of the valve and Fig. 3 is a cross-section along the line C-D of Fig. 2.
Bei den üblichen Wasserventilen besteht der Übelstand, daß, wenn bei geöffnetem Ventil das Wasser durch irgendeinen Grund fortbleibt, die Leitung also drucklos wird und das Ventil unbeaufsichtigt bleibt, bei Wiederkehr des Wasserdruckes leicht Wasserschäden entstehen können.With the usual water valves there is the disadvantage that if at open valve the water stays away for some reason, so the pipe becomes depressurized and the valve remains unattended when the water pressure returns water damage can easily occur.
Dieser Übelstand wird durch die Erfindung dadurch behoben, daß sich beim Wiedereintritt des Wasserdruckes ein Rückschlagventil automatisch schließt.This drawback is remedied by the invention in that when the water pressure re-enters, a check valve closes automatically.
Bei geöffnetem Ventilkegel 2 mittels des Handrades i und druckloser Leitung drückt die Feder 7 die Membran 5 und damit den Riegel 6 nach rechts. Hierdurch gibt der Riegel 6 bei der Nase 8 das Rückschlagventil 4 frei zum Schließen. Kehrt nun der Wasserdruck zurück, so wird das Rückschlagventil 4 durch den Druck automatisch geschlossen, denn zur Überwindung der Druckfeder 7 und damit wieder zur Sperrung des Rückschlagventils 4 bei der Nase 8 gehört ein größerer Wasserdruck als zur Schließung des Rückschlagventils 4.With the valve cone 2 open by means of the handwheel i and depressurized Line pushes the spring 7, the membrane 5 and thus the bolt 6 to the right. Through this is the bolt 6 at the nose 8, the check valve 4 free to close. Turns now the water pressure is back, the check valve 4 is automatically due to the pressure closed, because to overcome the compression spring 7 and thus again to the blocking of the check valve 4 at the nose 8 is a greater water pressure than the closure of the check valve 4.
Soll nun wieder Wasser aus dem Ventil entnommen werden, so muß erst der Ventilkegel 2 durch das Handrad i geschlossen werden. Dann drückt der mit dem Ventilkegel 2 fest verbundene Schaft 9 das Rückschlagventil 4 in die ursprüngliche geöffnete Stellung zurück. In geöffneter Stellung wird das Rückschlagventil4 durch die Nase 8 gehalten, denn das Druckwasser im Ventil hat inzwischen die Spiralfeder 7 überwunden und drückt die Membran 5 mit dem verbundenen Riegel 6 bis zum Anschlag nach links, und der gebrauchsfertige Zustand des Ventils ist wieder hergestellt.If water is to be removed from the valve again, it must first the valve cone 2 can be closed by the handwheel i. Then the one with the presses Valve cone 2 firmly connected shaft 9 the check valve 4 in the original open position back. In the open position, the check valve4 is through the nose 8 held because the pressurized water in the valve now has the spiral spring 7 overcome and presses the membrane 5 with the connected bolt 6 up to the stop to the left and the valve is ready for use again.
Damit der Schaft 9 so weit zurückgedreht werden muß, um die Schließung des Ventils 4 zu gewährleisten, ist an dem Ventilkegel 2 der zylindrische Ansatz io vorgesehen. Dieser Ansatz muß erst aus der zugehörigen Bohrung durch das Handrad i herausgehoben werden, bevor das Wasser fließen kann.So that the shaft 9 must be turned back so far to the closure To ensure the valve 4, the cylindrical extension is on the valve cone 2 io provided. This approach must first come from the associated hole through the handwheel i must be lifted out before the water can flow.
