A well water recirculation valve comprising an in-line check valve and a calibrated orifice through the body of the check valve. The orifice communicates through the body of the check valve into an unchecked end thereof. In use in a water well having a submersed pump, the recirculation valve is spliced into a well pipe at a location below the top of a well but above an average static water level in that well. The recirculation valve of the present invention recirculates a portion of the water pumped through the well pipe back into the well for preventing a stagnation of a head portion of that well.
Soupape de recirculation de l'eau de puits comprenant un clapet anti-retour sur canalisation et un orifice calibré dans le corps du clapet anti-retour. L'orifice communique par le corps du clapet anti-retour avec une extrémité non munie de clapet de ce dernier. Pendant son utilisation dans un puits d'eau équipé d'une pompe submersible, la soupape de recirculation est jointe à un tuyau de puits à un emplacement situé sous le sommet d'un puits mais au-dessus d'un niveau hydrostatique moyen dans ce puits. La soupape de recirculation de la présente invention recircule une partie de l'eau pompée par le tuyau du puits dans le puits pour prévenir une stagnation d'une partie de la charge de ce puits.
