ABSTRACT:
The device for purifying a flow of liquid by means of ultraviolet radiation, includes an elongated ultraviolet lamp; a generally tubular inner casing surrounding substantially the lamp, the casing being made of a material that allows transmission of ultraviolet radiation, the casing having an aperture at each end thereof from which the electrical terminals of the lamp protrude; and a generally tubular outer casing surrounding the inner casing and forming with it a flow passage, the outer casing being provided at substantially each of its ends with inlet and outlet for the flow of liquid. Two connectors are disposed respectively at both ends of the device for securing the lamp and the inner casing with respect to the outer casing. Each connector includes an annular liquid-tight removable seal disposed between inner and outer casings; an opaque electrical socket having a central cavity for receiving the corresponding terminal of the lamp; and a fixing device for securing the corresponding socket and seal with respect to said casings and lamp.
