Abstract
Description
La présente invention concerne le métier du traitement de l'eau.The present invention relates to the profession of water treatment.
Le métier dit du traitement de l'eau couvre les technologies les plus diverses telles que : l'adoucissement, la déminéralisation, la dénitratation, la déferrisation, la déchloration, la désalinisation, la désodorisation, la décarbonatation, l'osmose inverse, la neutralisation, l'eau ultra pure. Il s'agit donc d'un métier de compétences et de services afin de donner à l'eau publique les caractéristiques particulières correspondant à chacun de ses usagers, dans la quantité et ou la qualité requises. The so-called water treatment profession covers the most diverse technologies such as: softening, demineralisation, denitration, de-ironing, dechlorination, desalination, deodorization, decarbonation, reverse osmosis, neutralization , ultra pure water. It is therefore a profession of skills and services to give public water the special characteristics corresponding to each of its users, in the quantity and or quality required.
Dans notre métier, nous utilisons différents filtres, un contenant, dans lesquels nous fixons des cartouches de filtration dont le seuil de filtration est de 0,2 à 300 microns. Ce système de filtration est utilisé avant tout traitement bactériologique et 15 chimique. In our business, we use different filters, a container, in which we fix filter cartridges whose filtration threshold is from 0.2 to 300 microns. This filtration system is used before any bacteriological and chemical treatment.
Les filtres sont fabriqués depuis plus de trente ans en plastique ou en inox ou en acier divers. Ils sont composés d'un écrou de sécurité (A), d'une tête (B), d'un bol (C), 20 d'un joint torique (D), (voir descriptif figure N 1). Filters have been manufactured for over thirty years in plastic or stainless steel or various steel. They consist of a safety nut (A), a head (B), a bowl (C), an O-ring (D), (see description figure N 1).
L'invention que nous proposons peut être utilisée pour un filtre en acier inox ou en plastique. Elle permettra d'améliorer mais également de simplifier l'ouverture et la 25 fermeture de ce filtre. L'amélioration et la simplification constituent à fabriquer des glissières mâles coniques (E) et des glissières femelles (F), le bol (C) glisse dans les glissières (F) de la tête (B) pour venir serrer le joint torique (D) qui assure l'étanchéité. The invention that we propose can be used for a stainless steel or plastic filter. It will improve but also simplify the opening and closing of this filter. The improvement and simplification is to manufacture taper male slides (E) and female slides (F), the bowl (C) slides in the slides (F) of the head (B) to tighten the O-ring (D). ) which seals.
30 Une fois serré le filtre doit être très étanche pour supporter des pressions de 8 bars en service. Pour éviter le desserrage qui peut être causé par des coups de bélier sur les canalisations un écrou de sécurité (A) traverse la tête (B) et arrive à l'extrémité d'une glissière sur le bol (voir description figure N 2).Once tight the filter must be very tight to withstand 8 bar pressures in service. To prevent loosening which can be caused by water hammers on the pipes, a safety nut (A) passes through the head (B) and reaches the end of a slide on the bowl (see description figure N 2).
35 Grâce à cette invention l'injection des moules est facilitée puisque ce filtre a une pièce en moins, l'écrou qui est remplacé par le joint torique. De plus, l'injection est écourtée ce qui représente un coût moins élevé. Elle permet également d'éliminer le taraudage et le filetage utilisés 40 présent dans notre métier.Thanks to this invention the injection of the molds is facilitated since this filter has one less piece, the nut which is replaced by the O-ring. In addition, the injection is shortened which represents a lower cost. It also eliminates the tapping and threading used 40 present in our business.
