Abstract:
1. In a structure for sealing a UV lamp having an electrical cable and surrounding quartz tube through the wall of a pressurized fluid vessel, the improvement comprising: (a) a tubular member formed of quartz material with a UV lamp having an electrical cable extending therethrough; (b) a tubular fitting having opposite ends thereof externally threaded and having a radially outwardly extending flange thereon disposed intermediate the opposite threaded ends of the fitting; (c) a first annular seal disposed adjacent the flange wherein the external thread of one end of the fitting is engaged in a threaded aperture in the wall of the pressure vessel and the first annular seal is sealed between the flange and an exterior surface of the pressure vessel wall wherein, one end of the quartz tube extends into the tubular fitting; (d) an annular groove formed about the inner periphery of tubular fitting; (e) a second annular elastomeric seal disposed in the annular groove and sealing about the outer periphery of the quartz tube; (f) a nut threadedly engaging the end portion of the tubular fitting opposite the one end engaged in the threaded aperture, the nut having an axially extending portion with a central threaded aperture of a diameter less than the threaded engagement, wherein the electrical cable extends exteriorly of the quartz tube and through the central threaded aperture; (g) a flexure/strain relief member received over the electrical cable and closely interfitting the outer periphery thereof, the flexure/strain relief member including portion thereof engaging the central threaded aperture.
