  • the leakage warning device comprises receptacle 11, in the bottom of which is provided an opening 1 through which is insertable a water pipe 13.
  • the opening 12 surrounded by a flange 14, which can be applied against the pi 13 by aid of a hose clamp 15.
  • the flange 14 is an extension of cylindric socket 16, arranged around the bottom of the receptac 11.
  • a hose 20 is connected to the outlet openi 18 for leading away the leakage water, which possibly has be collected by the receptacle and which water is discharged, e.
  • T outlet end of the hose 20 is connected to an outlet fitting 2 which is preferably provided in the wall of the bathroom or t like some centimeters above the upper edge of the sill. It also possible to locate the outlet fitting above a dischar hopper, a bathtub or the like.
  • the outlet fitting 21 may equipped with several connections 21a, e.g. for hot water co water, radiator water etcetera.
  • the leakage warning device is alwa fitted below a connection, a valve, a welded or soldered joint a branch conduit.
  • it may be proper locate the branch inside the receptacle 11, which for th purpose is provided with one or more recess impression 23, whi after having been cut out form recesses for a branch conduit.
  • the leakage warning device can furthermore be provided with a l 24 equipped with a circumferential edge portion 25, which lid c be snapped onto the opening 26 of the receptacle 11.
  • the lid m also be provided with recess impressions (not shown), and it m also be slotted radially, thus that the lid may be thread on existing pipe conduits.
  • the leakage warning device shown in Fig.s 1 and 2 is primari intended to be used in new construction, whereas the t embodiments shown in Fig.s 3 to 8 are intended to be applied existing pipe conduits.
  • the receptacle 11 in the embodiment shown in Fig.s 3 - 5 is al an axial slot 27 designed with longitudinal flanges 28 and which will engage each other, and which by means of pro connecting means 30 may be brought to be pressed to a seal engagement against each other.
  • the inside of the flanges 28, are preferably provided with a longitudinal seal 31, e.g. sealing tape.
  • Fig.s 6 - 8 differs from embodiment shown in Fig.s 3 - 5 in that the longitudinal slot in the receptacle 11 is designed as a snap lock with tongues and 35, which may be snapped into each other. The tongues may glued, thus that a completely tight joint is obtained.
  • this embodiment has a branch portion 33 par arranged inside the receptacle 11 and partly in the lid 24.

Abstract

Dispositifs d'alerte en cas de fuite dans des conduites d'eau (13) ou conduites analogues se trouvant dans des espaces sans écoulement. Ce dispositif a la forme d'un récipient (11) dont le fond (17) est pourvu d'une ouverture (12) dans laquelle la conduite (13) peut s'insérer, cette ouverture étant disposée de manière à enrober la conduite (13) de façon à assurer l'étanchéité. L'ouverture (12) pratiquée dans le récipient (11) est élastique et munie de préférence d'une douille (22) s'évasant à l'intérieur par paliers successifs, chacun de ces paliers correspondant à un diamètre extérieur d'une conduite de dimensions courantes. A l'extérieur de la douille (16), on peut fixer un collier de serrage (15) ou un dispositif analogue pour plaquer l'ouverture (12) contre la conduite (13) de manière à assurer l'étanchéité. Dans la paroi du récipient, on a prévu au moins une empreinte cavité (23) et/ou au moins une douille latérale (33) pour recevoir une dérivation (13a) ou analogue sur la conduite. L'extrémité du tuyau d'évacuation (20), du côté de la décharge, peut être raccordée à une pièce de raccordement (21) servant à l'évacuation, qui est disposée de façon à déboucher dans une enceinte équipée d'un dispositif d'évacuation et séparée de l'espace où se trouve la conduite d'eau.
