Description

PERFECTIONNEMENTS AUX MECANISMES DE CHASSE DE W.C. DU TYPE A CLAPET A BILLES. IMPROVEMENTS IN BALL VALVE TYPE HUNTING MECHANISMS.
La quasi-totalité des réservoirs de chasse de W.C. sont équipés de robinets à flotteurs dont les inconvénients principaux sont d'être 5 extrêmement bruyants et de nécessiter un temps très long de remplissage. Dans le brevet publié sous le n°-2485061, le remplissage du ré¬ servoir est assuré par un clapet à billes qui est à la fois rapide et silencieux mais qui présente un risque de pollution du réseau de dis¬ tribution de 1 'eau. 0 La présente invention se rapporte à un mécanisme qui élimine ce risque en apportant des perfectionnements au clapet à billes et des aménagements visant à éliminer la perception du bruit. Elle se rap¬ porte enfin à des moyens rapides de montage de 1 'ensemble du mécanis¬ me dans le réservoir. Dans le brevet cité précédemment, l'intervention d'un clapet à billes de type connu- commence à l'issue de la vidange totale du réser¬ voir et après que la bonde se soit refermée. Dans la présente invention, un clapet à billes de type nouveau entre en action pour assurer le rem- • plissage au moment où la bonde de vidange arrive en fin de course d'ou- verture. Cette bonde est solidaire d'une tige verticale dont le mouve¬ ment de bas en haut s'effectue soit sous l'action de l'usager soit sous l'action d'un vérin hydraulique.Almost all of W.C.'s flush tanks are fitted with float valves, the main drawbacks of which are that they are extremely noisy and require a very long filling time. In the patent published under the number -2485061, the filling of the reservoir is ensured by a ball valve which is both fast and silent but which presents a risk of pollution of the water distribution network. 0 The present invention relates to a mechanism which eliminates this risk by providing improvements to the ball valve and arrangements aimed at eliminating the perception of noise. Finally, it relates to rapid means for mounting the whole of the mechanism in the tank. In the aforementioned patent, the intervention of a known type of ball valve begins at the end of the complete emptying of the reser¬ see and after the plug has closed. In the present invention, a new type ball valve comes into action to ensure filling when the drain plug reaches the end of the opening stroke. This plug is integral with a vertical rod whose movement from bottom to top is effected either under the action of the user or under the action of a hydraulic cylinder.
. Il est donné.pour une meilleure compréhension de l'invention et à titre d'exemples non limitatifs, deux modes de réalisations se référant aux dessins ci-annexés : Figure 1 : Vue longitudinale du dispositif à commande manuelle; Figure 2 : Vue longitudinale du dispositif à commande hydraulique; Figure 3 : Vue transversale du dispositif anti-bruit; Figure' : Vue longitudinale du dispositif anti-bruit et des moyens de fixation. La figure 1 comporte une bonde (2) qui obture ou libère alterna¬ tivement l'orifice d'expulsion (1). La bonde (2) est solidaire d'une tige verticale (3) qui se termine, à sa partie supérieure, par un bouton (4) par lequel, de l'extérieur, l'usager actionne l'ouverture de la bonde. Une pièce (5) solidaire de (3) est en position verticale et dirigée vers le haut. Elle est destinée à provoquer le soulèvement de la tige (7) d'un distributeur (6) à deux pistons respectivement celui du haut (8) et celui du bas (9). Ce distributeur (6), de type connu, est alimenté en eau par l'orifice (10). Il comporte un circuit supérieur qui, par l'orifice (11) et le conduit (12), alimente le clapet à billes (13), un circuit inférieur qui, par l'orifice (16) et le conduit (17) alimente un boîtier (18) à l'in¬ térieur duquel se trouve une bille (19) de densité supérieure à un, placée en regard d'un orifice de sortie (20) formant siège d'étanchéité et un cir¬ cuit qui, par l'orifice (14) et le conduit (15) fait communiquer le couver¬ cle du distributeur (6) avec le clapet à billes. Le fonctionnement du dispositif est le suivant , la tige (3) étant, au départ, abaissée, la bonde (2) obturant l'orifice (1) et la tige (7) étant dans la position figurée en traits pleins :. It is given for a better understanding of the invention and by way of nonlimiting examples, two embodiments referring to the attached drawings: FIG. 1: Longitudinal view of the device with manual control; Figure 2: Longitudinal view of the hydraulically operated device; Figure 3: Cross-section of the anti-noise device; Figure ' : Longitudinal view of the anti-noise device and the fixing means. Figure 1 includes a plug (2) which alternately closes or releases the expulsion orifice (1). The plug (2) is integral with a vertical rod (3) which ends, at its upper part, by a button (4) by which, from the outside, the user actuates the opening of the plug. A piece (5) integral with (3) is in a vertical position and directed upwards. It is intended to cause the lifting of the rod (7) from a distributor (6) with two pistons respectively that of the top (8) and that of the bottom (9). This distributor (6), of known type, is supplied with water through the orifice (10). It comprises an upper circuit which, via the orifice (11) and the conduit (12), feeds the ball valve (13), a lower circuit which, through the orifice (16) and the conduit (17) supplies a housing (18) inside which is a ball (19) of density greater than one, placed opposite an outlet orifice (20) forming a sealing seat and a cir¬ cuit which, by l orifice (14) and the conduit (15) communicates the cover of the distributor (6) with the ball valve. The operation of the device is as follows, the rod (3) being, at the start, lowered, the bung (2) closing the orifice (1) and the rod (7) being in the position shown in solid lines:
En soulevant le bouton (4), l'usager, dans un premier temps, pro¬ voque la vidange du réservoir puis, la pièce (5) entrant en contact avec la face inférieure du piston (9) déplace la tige (7) vers le haut pour V amener dans la position des pointillés qui correspond à l'ouverture du circuit du clapet à billes de sorte que le "réservoir se remplisse. De son côté, la bonde (2) retombe sur son siège d'étanchéité en même temps que se vide le réservoir ainsi que cela se produit dans tous les réservoirs actuel Lorsqu'à l'issue du remplissage, les billes du clapet se bloquent, la pres¬ sion s'exerce sur ]a face supérieure du piston (8) pour repousser la tige (7) vers le bas.By lifting the button (4), the user initially provokes the emptying of the reservoir, then the part (5) coming into contact with the underside of the piston (9) moves the rod (7) towards the top to bring to the position of the dotted lines which corresponds to the opening of the circuit of the ball valve so that the "tank is filled. On the other hand, the bung (2) falls back on its sealing seat at the same time that the tank empties as it does in all current tanks When after filling, the valve balls are blocked, the pressure is exerted on] the upper face of the piston (8) to repel the rod (7) down.
Dès que, par le déplacement du piston (8), l'orifice (11) cesse d'¬ être alimenté, l'orifice (16), par le déplacement du piston (9) commence à l'être. L'eau qui arrive en (10) force son passage vers (16) et exerce une poussée sur la face supérieure du piston (9) ce qui achève le mouve¬ ment de fermeture du distributeur (6). Le boîtier (18) se remplit d'eau et l'écoulement par l'orifice (20) provoque un flux qui aspire la bille (19) sur le siège d'étanchéité de (20) ce qui interrompt l'écoulement. Afin d'obtenir que cet écoulement soit suffisant en volume et dure assez de temps pour que soit achevé le déplacement de la tige (7), le boî¬ tier (Î8) contient un système quelconque de freinage de l'eau comme, par exemple, une série de chicanes (21).As soon as, by the displacement of the piston (8), the orifice (11) ceases to be supplied, the orifice (16), by the displacement of the piston (9) begins to be supplied. The water which arrives at (10) forces its passage towards (16) and exerts a push on the upper face of the piston (9) which completes the closing movement of the dispenser (6). The housing (18) fills with water and the flow through the orifice (20) causes a flow which sucks the ball (19) on the sealing seat of (20) which interrupts the flow. In order to obtain that this flow is sufficient in volume and lasts long enough for the displacement of the rod (7) to be completed, the housing (Î8) contains any system for braking the water such as, for example , a series of baffles (21).
Après blocage de la bille (19) sur le siège (20), l'ensemble se retrouve dans la position initiale, prêt à fonctionner à nouveau. Le deuxième cas correspond à la figure 2 dans laquelle la tige (24) du vérin hydraulique (23) porte, à sa partie inférieure, une rondelle rigide (25) qui, dans sa position basse, vient s'appliquer sur une ventous fixée sur le dessus de la bonde (22) de manière à se solidariser avec elle. La ventouse (26) porte à sa périphérie un élément quelconque comme, par exemple, une collerette (27) qui, au cours du soulèvement de la tige (24) entre en contact avec une butée- fixe (28) ce qui déforme le caoutchouc de (26). 'L'effet ventouse est alors supprimé, la ventouse (26) se détache sans effort de la rondelle (25) qui continue sa course, le réservoir se vide en même temps que la bonde (22) retombe sur son siège d'étanchéité.A l' issue du remplissage à nouveau du réservoir, avec le blocage des billes du clapet, la tige (24) redescend et la rondelle (25) vient se replaquer sur la ventouse (26) de manière à se retrouver en situation de soulever à nouveau la bonde (22) lors de l'opération suivante. Les figures î et 2 montrent les dispositifs nouveaux du clapet à billes dont les billes, la supérieure (29) et l'inférieure (30) sont toutes deux de densité supérieure à un. Elles sont logées et superposées dans le compartiment intérieur (31) du clapet à billes (13).After blocking of the ball (19) on the seat (20), the assembly returns to the initial position, ready to operate again. The second case corresponds to FIG. 2 in which the rod (24) of the hydraulic cylinder (23) carries, at its lower part, a rigid washer (25) which, in its low position, is applied to a suction cup fixed on the top of the drain (22) so as to join it. The suction cup (26) carries at its periphery any element such as, for example, a flange (27) which, during the lifting of the rod (24) comes into contact with a fixed stop (28) which deforms the rubber from (26). ' The suction effect is then eliminated, the suction cup (26) detaches effortlessly from the washer (25) which continues its stroke, the tank empties at the same time as the bung (22) falls back onto its sealing seat. At the end of the refilling of the tank, with the blocking of the balls of the valve, the rod (24) goes down again and the washer (25) comes back on the suction cup (26) so as to find itself in a situation of lifting at again the drain (22) during the following operation. Figures 1 and 2 show the new devices of the ball valve whose balls, the upper (29) and the lower (30) are both of density greater than one. They are housed and superimposed in the interior compartment (31) of the ball valve (13).
A la bille inférieure (30) correspond un orifice (32) formant siège d'étanchéité placé dans un plan sensiblement horizontal. Cet orifice (32) se prolonge vers le. bas par un élément de tuyau (33) qui débouche lui-mê¬ me dans une cavité (34) dont le couvercle est perforé pour l'échappement de l'air et dans laquelle coulisse un flotteur (35) qui porte, à sa partie supérieure, un têton (36) placé en regard du tuyau (33). Lorsque le niveau monte, le flotteur (35) monte avec lui, le têton (36) traverse le tuyau (33) et, en soulevant la bille (30), provoque le blocage du clapet dès que la poussée d'Archimède que subit le flotteur(35) devient supérieur au poids réuni des deux billes (29)(30).To the lower ball (30) corresponds an orifice (32) forming a sealing seat placed in a substantially horizontal plane. This orifice (32) extends towards the. bottom by a pipe element (33) which opens itself in a cavity (34) whose cover is perforated for the escape of air and in which slides a float (35) which carries, in its part upper, a pin (36) placed opposite the pipe (33). When the level rises, the float (35) rises with it, the stud (36) crosses the pipe (33) and, by lifting the ball (30), causes the blocking of the valve as soon as the Archimedes push that undergoes the float (35) becomes greater than the combined weight of the two balls (29) (30).
Le fond du compartiment (31) peut être garni d'une membrane en caoutchouc (37) qui ne gêne en rien le mouvement qui vient dêtre décrit mais qui isole le réseau de distribution du réservoir afin d'éliminer tout risque de pollution.The bottom of the compartment (31) can be lined with a rubber membrane (37) which does not hinder the movement which has just been described but which isolates the distribution network from the tank in order to eliminate any risk of pollution.
Les figures 3 et 4 montrent, en vues transversales et longitudinale le dispositif anti-bruit qui consiste à procéder à un double enfermement de ce bruit déjà très réduit grâce au clapet à billes : Le mécanisme (38) est logé dans une enveloppe (39) dans laquelle l'eau de la chasse est enmagasinée pour se vidanger par sa partie inféri¬ eure au moyen d'un orifice d'expulsion (42) se prolongeant vers le bas par un conduit (43) qui débouche directement dans la canalisation (41) de la cuvette. Pour permettre l'adaptation de l'enveloppe (39) dans le réservoir (40) quelque soit le diamètre de l'orifice inférieur (44) de ce réservoir (40), on peut utiliser un conduit (43) de forme tronçonnique dont l'ext¬ érieur vient se poser sur le rebord de l'orifice (44) et dont l'intérieur sert de siège d'étanchéité à la bonde (45) qui, dans ce cas, pourra avan- tageusement être choisie de forme sphérique.FIGS. 3 and 4 show, in transverse and longitudinal views, the anti-noise device which consists in double locking up this already very reduced noise thanks to the ball valve: The mechanism (38) is housed in an envelope (39) in which the flushing water is stored to empty through its lower part by means of an expulsion orifice (42) extending downwards by a conduit (43) which opens directly into the pipe (41) of the bowl. To allow the adaptation of the envelope (39) in the tank (40) whatever the diameter of the lower orifice (44) of this tank (40), one can use a pipe (43) of sectional shape whose l 'ext¬ er comes to rest on the edge of the orifice (44) and the interior of which serves as a sealing seat for the drain (45) which, in this case, can advantageously be chosen to be spherical.
On peut aussi, comme le montrent les figures 3 et 4, garnir l'ex¬ térieur du conduit (43) de nervures comme (46), (47), (47a) qui s'appuient sur le rebord de l'orifice (44) et ménagent entre elles des évidements qui mettent en communication la canalisation (41) avec l'espace compris entre l'extérieur de l'enveloppe (39) et l'intérieur du réservoir (40)It is also possible, as shown in FIGS. 3 and 4, to fill the outside of the duct (43) with ribs such as (46), (47), (47a) which rest on the edge of the orifice ( 44) and provide recesses therebetween which bring the pipe (41) into communication with the space between the outside of the envelope (39) and the inside of the tank (40)
Si le trop-plein de l'enveloppe (39) constituée d'un simple trou (48) entre en action, l'eau de ce trop-plein pourra ainsi s'évacuer vers la cuvette.If the overflow of the envelope (39) consisting of a single hole (48) comes into action, the water from this overflow can thus be evacuated towards the bowl.
Enfin la figure 3 montre le système de fixation rapide du mécanis- me (38) dans l'enveloppe (39) et de cette dernière dans le réservoir (40): Le mécanisme (38) porte, sur chacune de ces faces latérales, une tige rectilîgne de section polygonale soit deux tiges, respectivement (49) et (50) disposées en alignement et perpendiculairement au plan médian longitudinal (51) du mécanisme (38). L'empâtement total entre les extrêmi- tés (52) et (53) des tiges (49) et (50) est supérieur à la largeur intéri¬ eure de l'enveloppe (39) laquelle comporte, sur chacune de ses faces laté¬ rales, en correspondance avec les tiges (49) et (50) et de même forme polygonale, un bossage creuxsoit deux bossages respectivement (54) et (55) sur le fond desquels viennent s'encastrer les extrémités (52) et (53), ce qui a pour effet de solidariser fixement le mécanisme (38) avec l'en¬ veloppe (39) et de manière amovible du fait que le montage comme le démon¬ tage s'effectue par écartement élastique des parois latérales de l'envelop¬ pe (39).Finally, FIG. 3 shows the quick fixing system of the mechanism (38) in the casing (39) and of the latter in the tank (40): The mechanism (38) carries, on each of these lateral faces, a straight rod of polygonal cross section, ie two rods, respectively (49) and (50) arranged in alignment and perpendicular to the longitudinal median plane (51) of the mechanism (38). The total impasto between the ends (52) and (53) of the rods (49) and (50) is greater than the interior width of the casing (39) which comprises, on each of its laté¬ sides rales, in correspondence with the rods (49) and (50) and of the same polygonal shape, a hollow boss or two bosses respectively (54) and (55) on the bottom of which the ends (52) and (53) are fitted , which has the effect of securing fixedly the mechanism (38) with the envelope (39) and removably because the assembly as the demon¬ tage is effected by elastic spacing of the side walls of the envelope ¬ pe (39).
Les tiges (49) et (50) sont évidées de trous cylindriques borgnes et taraudés, respectivement (56) et (57) tandis que les fonds des bossages (54) et (55) comportent des trous (58) et (59) par lesquels on introduit dans (56) et (57) des vis (60) et (61) dont, lorsqu'on les dévisse, les têtes (62) et (63) viennent, par leurs faces externes, s'appliquer sur les parois latérales internes du réservoir (40), et agissent comme des étrésillons en solidarisant fixement mais de manière amovible l'enveloppe (39) avec le réservoir (40). The rods (49) and (50) are hollowed out with blind and tapped cylindrical holes, respectively (56) and (57) while the bottoms of the bosses (54) and (55) have holes (58) and (59) through which are introduced into (56) and (57) screws (60) and (61) of which, when they are unscrewed, the heads (62 ) and (63) come, by their external faces, to be applied on the internal lateral walls of the tank (40), and act like struts by securing fixedly but removably the casing (39) with the tank (40) .
