A completamento del processo di depurazione delle acque reflue civili o industriali esiste una serie di dispositivi realizzati interamente da COSME che supportano l’ impianto in ogni sua fase lavorativa costituendone parte integrante.
HOW IT WORKS
The clapet valve is used as a no-return valve in the openings of communication between partition areas in the concrete tanks. Opening of valve is made only in one direction. If pressure due to water column upstream valve is higher than that downstream, valve opens and lets water pass. Vice versa valve closes.
HOW IT IS BUILT
Bearing structure with fixing to wall, complete of articulated joint, so that shield adapts to wall.
Stiffened shield complete of peripheral sealing gasket in EPDM.
Adjustable counter-weights for manual calibration of opening pressure.
