Abstract
Description
La présente invention concerne une nouvelle vanne qui est utilisable en particulier pour la vidange de réservoirs d'eaux usées mais qui peut évidemment être employée dans de nombreuses autres applicati#ns car sa ré#lisati-on fait qu'elle permet de vidanger un réservoir ou d'ouvrir un circuit dans lequel circule un liquide sans que l'opérateur soit mouillé par ce liquide,
Par ailleurs, la réalisation de la vanne de l'invention fait qu'elle peut être fabriquée de façon extrêmement bon marché et que son fonct.ionnement est d'une grande sûreté tant en ce qui concerne l'étanchéité que la facilité de ma noeuvre qui ne nécessite normalement aucun outil.The present invention relates to a new valve which can be used in particular for emptying waste water tanks but which can obviously be used in many other applications because its re # lisati-on means that it allows a tank to be emptied or to open a circuit in which a liquid circulates without the operator being wet by this liquid,
Furthermore, the realization of the valve of the invention means that it can be manufactured in an extremely inexpensive manner and that its operation is very safe both in terms of the tightness and the ease of my work. which normally requires no tools.
En outre, les avantages énoncés ci-dessus de la vanne de l'invention font qu'elle trouve une utilisation tout par ticulièrement avantageuse pour la vidange de réservoirs d'eaux usées du genre de ceux qui sont utilisés dans des véhicules de loisir,
Conformément a l'invention, la vanne comporte un corps tubulaire fermé au voisinage de son extrémité opposée a celle reliée au réservoir, un trou étant prévu dans la paroi latéral le dudit corps avant l'extrdmite fermée et un couvercle étant enfilé sur l'extrémité du corps de façon à recouvrir ledit trou et à serrer au moins une garniture d'étanchéité disposée sur le corps tubulaire entre le trou et l'extrémité de ce corps reliée au réservoir.In addition, the advantages set out above of the valve of the invention mean that it finds a use which is particularly advantageous for the emptying of waste water tanks of the kind which are used in recreational vehicles,
According to the invention, the valve comprises a tubular body closed in the vicinity of its end opposite to that connected to the reservoir, a hole being provided in the side wall of said body before the end closed and a cover being threaded on the end. of the body so as to cover said hole and to clamp at least one seal fitted on the tubular body between the hole and the end of this body connected to the reservoir.
Diverses autres caractéristiques de l'invention ressortent d'ailleurs de la description détaillée qui suit. Various other characteristics of the invention will also emerge from the detailed description which follows.
Des formes de réalisation de l'objet de l'invention sont représentées, a titre d'exemples non limitatifs, au dessin annexé. Embodiments of the object of the invention are shown, by way of nonlimiting examples, in the accompanying drawing.
La fig, 1 est une coupe-élévation éclatée d'un premier mode de réalisation de la vanne de l'invention,
La fig, 2 est une coupevelevation de la vanne en position de fermeture montée d la sortie d'un réservoir,
La fig, 3 est une coupe-élévation éclatée analogue à la fig. 1 d'une variante,
La fig, 4 est une coupe éclatée analogue aux figu res précédentes d'une seconda variante,
ta vanne suivant les fig, 1 et 2 comporte un corps tubulaire 1 près d'une extrémité duquel est pratiqué un trou 2, Un fourreau 3 est enfilé sur le corps 1 et fi- xé, par exemple par collage ou encore par soudure a la cha leur Si le corps 1 est fabriqué en matière thermoplastique
Le fourreau 3 forme une butée 3a pour un joint d'étant chiite souple 4,
A une extrémité, le corps 1 est muni d'une douille taraudée 5 qui est fermée par une pastille 6.La douille 5 est fixée au corps 1 de manière analogue au fourreau 3,
La vanne comporte, supplémentairement, un bouchon 7, tubulaire, qui est muni d'un fond 8 a partir duquel fait saillie un embout fileté 9 dont le pas correspond à celui du taraudage de la douille 5,
Bien que cela ne soit pas nécessaire dans tous les cas, il est avantageux que le corps tubulaire 1 présente, entre le fourreau 3 et le trou 2, une rainure pour un joint torique 10.FIG. 1 is an exploded sectional elevation of a first embodiment of the valve of the invention,
Fig, 2 is a sectional elevation of the valve in the closed position mounted from the outlet of a tank,
FIG. 3 is an exploded sectional elevation similar to FIG. 1 of a variant,
FIG. 4 is an exploded section similar to the previous figures of a second variant,
your valve according to figs, 1 and 2 comprises a tubular body 1 near one end of which a hole 2 is made, a sleeve 3 is threaded on the body 1 and fixed, for example by gluing or by welding with cha if the body 1 is made of thermoplastic material
The sheath 3 forms a stop 3a for a flexible Shiite seal 4,
At one end, the body 1 is provided with a threaded sleeve 5 which is closed by a patch 6. The sleeve 5 is fixed to the body 1 in a similar manner to the sleeve 3,
The valve additionally comprises a tubular plug 7 which is provided with a bottom 8 from which a threaded end 9 projects, the pitch of which corresponds to that of the thread of the sleeve 5,
Although this is not necessary in all cases, it is advantageous for the tubular body 1 to have, between the sleeve 3 and the hole 2, a groove for an O-ring 10.
La fig. 2 montre que le corps de vanne 1 est destiné à être raccordé par un manchon il ou autre organe au raccord de vidange 12 d'un réservoir 13. Il est avantageux que le manchon 11 soit coudé pour que la vanne se trouve dans une position sensiblement horizontale ou qu'elle puisse être amenée facilement dans cette position avec le trou 2 dirigé vers le bas. Par ailleurs, la longueur du corps tubulaire est choisie de façon qu'il puisse être facilement saisi à la main entre sa partie fixée au manchon 11 et le fourreau 3.En position de fermeture, le bouchon 7 est visse dans le taraudage de la douille 5r de sorte qu'il prend appui par son extrémité sur le joint souple d'étanchéité 4,
Si l'on désire vidanger le réservoir 13, il suffit de dévisser le bouchon 7 jusqu'au moment ot celui-ci découvre le trou 2 et le liquide s'écoule alors comme illustré par la flèche de la fig. 1,
Lorsqu'un joint torique supplémentaire 10 est prévu, le liquide ne peut pa,s s 'insinuer entre la paroi interne du bouchon et son extrémité lorsque cette extremite n'est plus appliquée contre le joint souple 4, ce qui évite que du li- quide suinte avant que le trou 2 soit découvert par le bouchon,
La fig. 3 illustre une variante de réalisation avantageuse lors d'une fabrication par moulage. Dans ce casf le corps tubulaire la forme directement la butée 3a et il présente, près d'une de ses extrémités, une cloison transversale 6a et un taraudage 14, Le couvercle 7a est alors fabriqué également en une seule pièce par moulage et délimite ainsi un fond 8a et un embout fileté 9a.Fig. 2 shows that the valve body 1 is intended to be connected by a sleeve it or another member to the drain connection 12 of a reservoir 13. It is advantageous that the sleeve 11 is bent so that the valve is in a position substantially horizontal or that it can be easily brought into this position with the hole 2 directed downwards. Furthermore, the length of the tubular body is chosen so that it can be easily grasped by hand between its part fixed to the sleeve 11 and the sheath 3. In the closed position, the plug 7 is screwed into the thread of the sleeve. 5r so that it bears at its end on the flexible seal 4,
If it is desired to empty the reservoir 13, it suffices to unscrew the cap 7 until the moment it discovers the hole 2 and the liquid then flows as illustrated by the arrow in FIG. 1,
When an additional O-ring 10 is provided, the liquid cannot penetrate between the internal wall of the stopper and its end when this end is no longer applied against the flexible seal 4, which avoids that of the liquid oozes before hole 2 is exposed by the plug,
Fig. 3 illustrates an advantageous alternative embodiment during manufacture by molding. In this case the tubular body directly forms the stop 3a and it has, near one of its ends, a transverse partition 6a and a thread 14, The cover 7a is then also manufactured in one piece by molding and thus delimits a bottom 8a and a threaded end 9a.
Comme précédemment, le corps la présente un trou 2 et la butée 3a sert d'appui au joint d'étanchéité 4. De même, il est avantageux de prévoir le joint torique 10. As before, the body has a hole 2 and the stop 3a serves to support the seal 4. Similarly, it is advantageous to provide the O-ring 10.
La fig. 4 illustre une autre variante de réalisation selon laquelle le corps tubulaire lb comporte, comme la fig. Fig. 4 illustrates another alternative embodiment according to which the tubular body 1b comprises, as in FIG.
3, la butée 3a pour le joint d'étanchéité 4 et également, comme à la fig. 3, il présente un trou 2 pour l'écoulement du liquide. Selon cette variante, l'une des extrémités du corps tubulaire comporte un fond 66 et l'extrémité présent tant ce fond délimite un filetage 15.3, the stop 3a for the seal 4 and also, as in FIG. 3, it has a hole 2 for the flow of the liquid. According to this variant, one of the ends of the tubular body has a bottom 66 and the end present as this bottom defines a thread 15.
Dans cette réalisation, le bouchon 7b qui est tubulaire délimite un taraudage- 16 près de son fond Eb et un taraudage auxiliaire 17 près de son embouchure. Pour fermer la vanne, il suffit de visser le bouchon sur le filetage ge 15 du corps tubulaire, c'est-à-dire qu'on visse tout d'abord le taraudage 17 qui passe au des du filetage 15, puis on visse le taraudage 16 sur le filetage 15. In this embodiment, the plug 7b which is tubular delimits a thread 16 near its bottom Eb and an auxiliary thread 17 near its mouth. To close the valve, it suffices to screw the plug onto the thread ge 15 of the tubular body, that is to say first of all screw the thread 17 which passes to the end of the thread 15, then screw the thread 16 on thread 15.
L'étanchéfté est réalisée comme dans les exemples précédents et ce mode de réalisation présente, en outre, l'avantage que le bouchon ne peut pas être séparé accidentellement du corps tubulaire. En effet, pour le séparer il est nécessaire de procéder au dévissage du taraudage 17 par rapport au filetage 15, ledit taraudage 17 servant normalement de butée d'arrêt. Bien entendu, la longueur sur laquelle est pratiqué le taraudage 17 est inférieure à la distance sépar#nt l'extrémité du filetage 15 du bord du trou 2,
L'invention n'est pas limitée aux exemples de réalisation représentés et décrits en détail, car diverses modifi- cations peuvent y être apportées sans sortir de son cadre,
En particulier, la butée 3a peut être prévue pour être emboitée et, éventuellement, encliquetée dans un support prévu pour que seul le bouchon 7, 7a ou Sh soit accessible De même, ce bouchon ou son fond peut être aménagé pour permettre la mise en place d'une clé ou d'un autre organe facilitant le desserrage. The sealing is carried out as in the previous examples and this embodiment has the additional advantage that the plug cannot be accidentally separated from the tubular body. Indeed, to separate it it is necessary to unscrew the thread 17 relative to the thread 15, said thread 17 normally serving as a stop. Of course, the length over which the tapping 17 is made is less than the distance separating the end of the thread 15 from the edge of the hole 2,
The invention is not limited to the exemplary embodiments shown and described in detail, since various modifications can be made without departing from its scope,
In particular, the stop 3a can be provided to be nested and, possibly, snapped into a support provided so that only the plug 7, 7a or Sh is accessible Similarly, this plug or its bottom can be arranged to allow the establishment a key or other device to facilitate loosening.
