Description

Ilobinet ä decharge. Le plus generalement, une distribution d'eau ä domicile comporte deux parties: 1"une, interieure, partant de 1'arigine du branchement et abautissant ä 1'appareil de contröle (compteur d'eau), s'il existe, dopt la responsabilite incombe ä, 1'usager et une deuxieme representee par la-conduite d'ame- nee situee en amont du branehement et qui concerne 1e service concessionnaire. Discharge valve. Most generally, a water supply at home comprises two parts: 1"one, interior, starting from the origin of the connection and lowering to the control device (water meter), if it exists, adopts the responsibility rests with the user and a second represented by the supply pipe located upstream of the connection and which concerns the concessionary service.

Le plus souvent, la. premiere partie ne peut eire efficacement garantie du gel que par sa vidange complete. Les robinets dits "ä decharge", dun usage ä peu pres courant, ne permettent pas d'obtenir ce resultat. Most often, the. first part can only be effectively guaranteed against freezing by completely draining it. The so-called "discharge" taps, which are almost commonly used, do not allow this result to be obtained.

En effet, leur fonctionnement ne permet ras de reali@ser ä co-up sür la fermeture de 1'orifice d'arrivee lors du fonctionnement de 1a decharge. Les Services concessionnaires ne peuvent, pour cette raison, autoriser leür pla- cement qu'en a.val des compteurs; ceux-ei restent donc constamment remplis d'eau, et par Suite susceptibles de subir des det6rioTa- tions dues au gel. Le robinet faisant 1'objet de la presente invention a pour but de combler cette lacune. In fact, their operation does not make it possible to simultaneously realize the closing of the inlet orifice during the operation of the discharge. The Concessionaire Services can, for this reason, authorize their installation only downstream of the meters; they therefore remain constantly filled with water, and are therefore liable to damage due to frost. The valve forming the subject of the present invention aims to fill this gap.

Ce robinet, du type ä decharge, est carac- teris6 par un piston pouvant etre deplace Jans les deux sens suivant son axe longitudi- nal, dann un cylindre formant corps du robi- net, des orifices, trous evidements et soupapes portes par 1e corps du robinet et 1e piston etant disposes entre eux de telle fagon que 1e deplacement dudit piston permette d'obte- nir trois positions de fonetionnement corres- pondant l'une ä la fermetnre et la vidange, la, deuxieme ä la fermeture simple et la troi- si6me ä 1'ouverture normale. This tap, of the discharge type, is characterized by a piston which can be moved in both directions along its longitudinal axis, in a cylinder forming the body of the tap, orifices, recessed holes and valves carried by the body. of the valve and the piston being arranged between them in such a way that the displacement of the said piston makes it possible to obtain three operating positions corresponding to one of the closing and emptying, the second to the simple closing and the third - si6me at normal opening.

Il peut etre en outre muni dune prise d'air supplementaire pour faciliter la vidange en permettant 1'acces de fair ä un point quel- conque de la conduite dont la vidange est plus diffioile. It may also be provided with an additional air intake to facilitate emptying by allowing access to any point in the pipe where emptying is more difficult.

Le dessin ei-annexe donne ä titre d'exem- ple, represente deux formes d'exeoution de 1'objet de 1'invention. Fig. 1 est une vue en coupe du robinet selon la Premiere forme d'execution, dans la Position de vidange, Fig. 2 une vue en coupe du meme robinet dans la Position de fermeture; Fig. 3 en est une vue en plan avec coupe partielle suivant la ligne 3-3 de la fig. 2; Fig. 4 en est une vue en coupe dans la Position d'ouverture; Fig. 5 est une vue en coupe dune autre forme d'execution du robinet dans la Posi tion de fermeture et vidange; Fig. 6 en est une vue en coupe dans la Position de fermeture simple; Fig. 7 en es.t une vue en coupe dans la Position d'ouverture. The attached drawing, given by way of example, shows two embodiments of the object of the invention. Fig. 1 is a sectional view of the tap according to the first embodiment, in the emptying position, FIG. 2 a sectional view of the same valve in the closed position; Fig. 3 is a plan view with partial section along line 3-3 of FIG. 2; Fig. 4 is a cross-sectional view thereof in the open position; Fig. 5 is a cross-sectional view of another form of execution of the tap in the closed and emptying position; Fig. 6 is a cross-sectional view thereof in the Single Closing Position; Fig. 7 is a cross-sectional view in the Open Position.

Le robinet represente aux fig. 1 ä 4 est avec Prise d'air supplementaire. Il se com- pose des organes et pieces essentielles sui- vantes I. Un Corps 2 comprenant: 1o Un orifice d'entree 3 branche ä la con- duite d'amenee,-un orifice de sortie 4 bran- che ä la distribution en aval et un troisieme orifice 5 permettant, au moment voulu, 1e Passage de Fair exterieur; 20 Trois evidements interieurs circulaires. 6, 7, 8 communiquant chacun avec 1'un des trois orifices indiques ei-dessus ; 30 Deux alesages 9 et 10, ayant pour but de realiser de Part et d'autre de 1'evidement 6 deux nervures circulaires servant d'appui ä des garnitures d'etancheite. The valve shown in Figs. 1 to 4 is with additional air intake. It is made up of the following essential organs and parts I. A Body 2 comprising: 1o An inlet orifice 3 connected to the supply pipe, an outlet orifice 4 connected to the distribution in downstream and a third orifice 5 allowing, at the desired time, the first passage of exterior Fair; 20 Three circular interior recesses. 6, 7, 8 each communicating with one of the three orifices indicated above; 30 Two bores 9 and 10, having the purpose of realizing on either side of the recess 6 two circular ribs serving as a support for sealing gaskets.

II. Une piece cylindrique 11, ou piston, d'un diametre sensiblement egal ä celui de 10 et evide en son centre en 12 et 13; sur son pourtour ce piston Porte trois rangees de trous 14, 15, 16 judicieusement situes, de- bouchant dans les evidements 12 et13. Le piston Porte egalement un trou borgne 17. II. A cylindrical piece 11, or piston, of a diameter substantially equal to that of 10 and hollowed out at its center at 12 and 13; on its periphery this piston carries three rows of holes 14, 15, 16 judiciously located, opening into the recesses 12 and13. The piston also carries a blind hole 17.

Ce piston recoit aussi ä sa base, par fi- letage, un siege de soupape 18 et son clapet 19, dont la tige est guidee par 1e trou 17 et un autre trou 20 perce dans la paroi infe- rieure du siege de soupape. Un ressort 21 tend ä appliquer 1e clapet sur son siege: L'6- videment superieur du piston est filete pour recevoir urie rondelle au centre de laquelle tourillonne ä demeure une tige fileUe 22 ser- vant ä la commande du piston. This piston also receives at its base, by threading, a valve seat 18 and its poppet 19, the stem of which is guided by the hole 17 and another hole 20 drilled in the lower wall of the valve seat. A spring 21 tends to apply the valve to its seat: The upper recess of the piston is threaded to receive a washer in the center of which a threaded rod 22 permanently pivots, serving to control the piston.

III. Un ensemble de bagues et de garni- -tures qui ont pour but d'obtenir 1e glissement etanche du piston 11 dans 1e Corps 2, soit: une bague bronze 23, des garnitures 24, une bague entretoise 25 percee et evidee, des garnitures 26 et 27, une bague entretoise 28 percee et evidee, des garnitures 29 et une bague de blocage 30 munie ä la Partie infe- rieure de trous 36. III. A set of rings and gaskets which are intended to obtain the first leaktight sliding of the piston 11 in the first body 2, i.e.: a bronze ring 23, gaskets 24, a spacer ring 25 drilled and hollowed out, gaskets 26 and 27, a spacer ring 28 pierced and hollowed out, gaskets 29 and a locking ring 30 provided with holes 36 in the lower part.

IV. Un Chapeau 32 visse ä la Partie su- perieure du Corps, comprimant les garnitures par 1'intermediaire de la bague 23 et servant d'.ecrou ä la tige 22. Ce Chapeau est RTI ID="0002.0274" WI="8" HE="4" LX="1858" LY="920"> muni d*orifices d'entree d'air 33. V. Un bouchon 34 visse ä la Partie infe- rieure du Corps, comprimant les garnitures par 1'intermediaire de 1a bague 30 et servant egalement, par son bossage 35 situe dans 1e fond, de butäe ä la tige du clapet 19 et au piston 11. La paroi du bouchon 34 comporte des trous de vidange 31. Le fonctionnement de ce robinet est 1e suivant: Le robinet est branche, dune pari, ä 1a conduite d'arrivee d'eau par son orifice 3 et, d'autre Part, ä la conduite de distribution par son orifice 4. IV. A Cap 32 screws to the Upper Part of the Body, compressing the gaskets through the intermediary of the ring 23 and serving as a nut for the rod 22. This Cap is RTI ID="0002.0274" WI="8" HE ="4" LX="1858" LY="920"> provided with air inlets 33. the ring 30 and also serving, via its boss 35 located in the bottom, as a stop for the stem of the valve 19 and the piston 11. The wall of the plug 34 has drain holes 31. The operation of this valve is as follows: The tap is connected, on the one hand, to the water supply pipe through its orifice 3 and, on the other hand, to the distribution pipe through its orifice 4.

Lorsque 1e piston 11 se trouve dans la Position la plus hasse correspondant ä la Po sition de vidange (fig. 1), 1'eau qui entre par Forifice 3 penetre Jans Fevidement 6, mais ne peut aller plus loin, en raison de Finter- position entre 1e Corps de robinet 2 et 1e pis- ton 11 des garnitures comprimees 26 et 27. When the piston 11 is in the lowest position corresponding to the emptying position (fig. 1), the water which enters through the orifice 3 enters the recess 6, but cannot go any further, because of the inter- position between the valve body 2 and the piston 11 of the compressed seals 26 and 27.

D'autre Part, Forifice 4 relie ä la conduite de distribution est en communication avec Fextärieur par Fintermediaire de la bague entretoise 28, des trous 16 du piston, de 1'e- videment 12 du siege 18, des orifices 36, de la bague 30 et des trous 31 perces dans la paroi du bouchon 34. Etant doune que 1e clapet 19 est alors souleve de dessus son siege, sa tige etant sou- lev6e par 1e bossage 35, 1'eau peut alors s'e- couler librement par les trous 36 de la bague 30 et les trous 31 du bouchon 34. On the other hand, the orifice 4 connected to the distribution pipe is in communication with the exterior through the intermediary of the spacer ring 28, the holes 16 of the piston, the recess 12 of the seat 18, the orifices 36, the ring 30 and holes 31 drilled in the wall of the stopper 34. Since the valve 19 is then lifted from its seat, its stem being lifted by the boss 35, the water can then flow freely through the holes 36 of the ring 30 and the holes 31 of the cap 34.

Dans 1e mode d'exkution represente par 1e dessin, 1e robinet est prevu avec Prise d'air supplementaire destink ä faciliter la vi- d.ange. Cette Prise fonctionne de la maniere suivante: Forifice de Prise d'air 5 etant rac- cord6 par une tuyauterie ä 1'appareil ou au point de la con.duite de distribution dopt la vidange est plus difficile, Fair peut pene- trer librement par les orifices 33 du chapeau 32, rejoindre 1'orifice 5 en Passant par 1'inte- rieur de la bague 23, 1'evidement 13 du pis- ton, les trous 14 et la bague 25, pour attein- dre de 1ä la capacite oü une entrk d'air est nF-cessaire pour en assurer la vidange. In the mode of execution represented by the drawing, the tap is provided with an additional air intake intended to facilitate emptying. This Intake works in the following way: the Air Intake orifice 5 being connected by a pipe to the appliance or to the point of the distribution pipe where the draining is more difficult, Air can enter freely through the orifices 33 of the bonnet 32, join the orifice 5 Passing through the inside of the ring 23, the recess 13 of the piston, the holes 14 and the ring 25, to reach the capacity of 15 where an air inlet is necessary to ensure emptying.

Cette Position correspond donc ä la fer- meture cöte arrivee et ä la communication de la conduite de distribution avec 1'exterieur, donc ä la vidange de cette conduite, ladite vi- dange Uant facilitee par une Prise d'air sup- plementaire. This position therefore corresponds to the closing on the arrival side and to the communication of the distribution pipe with the outside, therefore to the emptying of this pipe, said emptying being facilitated by an additional air intake.

Si Fon deplace 1e piston de bas en haut, par la manoeuvre de la tige 22, pour Fame- ner dans la po@sition representee par la fig. 2 correspondant ä la feimeture normale du ro- binet, la communication entre les orifices 4 et 3 est toujours interceptee, les troüs 15 etant toujours obtures par les garnitures 27, mais 1e clapet 19 repose sur son siege, em- pAchant la vidange. D'autre Part, il ne peut y avair introduction d'air dans la conduite de distribution, les trous 14 se trouvant obtures par les garnitures 24. If Fon moves the piston from bottom to top, by operating rod 22, to bring it into the position represented by FIG. 2 corresponding to the normal closure of the tap, the communication between the orifices 4 and 3 is always intercepted, the holes 15 being always closed by the gaskets 27, but the valve 19 rests on its seat, preventing emptying. On the other hand, there can be no introduction of air into the distribution pipe, the holes 14 being closed by the fittings 24.

Cette Position correspond par consequent ä la fermeture simple du robinet. This Position therefore corresponds to the simple closing of the valve.

Pour ouvrir 1e robinet, an amene le pis- ton, en manoeuvrant la tige 22 dans 1e meme sens que precedemment ä son point 1e plus eleve, jusqu'ä ce que 1e haut du piston bute contre 1e fand du chapeau 32 (fig. 4). Dans cette Position, les orifices d'entree 3 et de sortie 4 sont en communication, la vidange et la Prise d'air sont fermees. Le chemin suivi par Feau est 1e suivant: Elle entre par 1'orifice 3 et se rend dans 1'evidement 6 oü -debouchent maintenant les trous 15 du piston; elle penetre ensuite par lesdits trous dans 1'evidement 12 du piston, trouve Pas sage par les trous 16, traverse la bague 28 par les trous quelle comporte et arrive ä 1'orifice 4. To open the valve, move the piston, moving the rod 22 in the same direction as before at its highest point, until the top of the piston abuts against the fand of the bonnet 32 (fig. 4). ). In this Position, the inlet 3 and outlet 4 orifices are in communication, the drain and the Air Intake are closed. The path followed by the water is the following: It enters through the orifice 3 and goes into the recess 6 where the holes 15 of the piston now emerge; it then enters through said holes in the recess 12 of the piston, finds the passage through holes 16, passes through ring 28 through the holes which it contains and arrives at orifice 4.

Cette Position correspondant ä 1'ouver- ture normale du robinet est similaire ä celle que peut donner un robinet ordinaire dit RTI ID="0003.0276" WI="5" HE="3" LX="1705" LY="510"> ro- binet ä deux eaux. This position corresponding to the normal opening of the valve is similar to that which can be given by an ordinary valve called RTI ID="0003.0276" WI="5" HE="3" LX="1705" LY="510"> two-water tap.

Il est evident que par une manaeuvre in verse de la tige 22 du piston, an pourrait faire passer successivement celui-ci de la po- sitien ouverture normale (fig. 4) ä la Position fermeture simple (fig. 2) et ä la Position fermeture et vidange (fig. 1). It is obvious that by a reverse operation of the rod 22 of the piston, an could make pass successively this one from the normal opening position (fig. 4) to the Simple closing position (fig. 2) and to the Position closing and emptying (fig. 1).

Le robinet montre par les fig. 5 ä 7 com- prend les meme organes et pieces essentielles que celui qui vient d'etre dkrit: 10 Un corps 41 comprenant: c,) Un orifice d'entree 42 branche ä la conduite d'amenk, un orifice de sortie 43 branche ä la distribution en aval et un troi- sieme orifice 44 permettant au moment voulu 1e Passage de Fair exterieur; b) Trois evidements interieurs circulaires 45, 46, 47, communiquant chacun avec 1'un des trois orifices indiques ei-dessus; c) Deug alesages 48 et 49 ayant pour but de realiser de Part et d'autre de l'evidement 45 deux nervures circulaires servant d'appui ä .des garnitures d'etancheite. The valve shown by figs. 5 to 7 comprises the same organs and essential parts as that which has just been described: 10 A body 41 comprising: c,) An inlet orifice 42 connected to the supply pipe , an outlet orifice 43 connects to the downstream distribution and a third orifice 44 allowing, when desired, the passage of external air; b) Three inner circular recesses 45, 46, 47, each communicating with one of the three orifices indicated above; c) Deug bores 48 and 49 having the purpose of realizing on either side of the recess 45 two circular ribs serving as a support for sealing gaskets.

20 Une pike cylindrique ou piston 50 d'un diametre sensiblement egal ä. celui de 49 et evide en son centre en 51 et 52. Sur son pourtour, ce piston Porte trois rangees de trous 53, 54, 55 judicieusement sitaes et debouchant dans les evidements 51 et 52. 20 A cylindrical pike or piston 50 of a diameter substantially equal to. that of 49 and recessed in its center at 51 and 52. On its periphery, this piston carries three rows of holes 53, 54, 55 judiciously located and opening into the recesses 51 and 52.

Le piston 50 a une forme plus allongee que celui du robinet montre fig. 1 ä 4. Comme dans ce dernier, 1'evidement supe- rieur 51 est filete pour recevoir une ron- delle au centre de laquelle tourillonne une tige de commande 56 filetee servant ä la commande du piston. Le piston 50 a sa Base fileMe pour rece- voir, ä la place de la soupape, un bauchon 57 de fermeture Manche. The piston 50 has a more elongated shape than that of the valve shown in FIG. 1 to 4. As in the latter, the upper recess 51 is threaded to receive a washer at the center of which is journalled a threaded control rod 56 serving to control the piston. The piston 50 has its Base threaded to receive, in place of the valve, a Sleeve closure cap 57.

30 Un ensemble de bagues et de garni tures qui ont pour but d'obtenir 1e glissement etanche du piston 50 dans 1e corps 41, soit: une bague Bronze 58 ä. la Partie süperieure, bague comportant un trou 59 correspondant ä celui d'admission d'air 60 pratique dans 1e eorps du robinet, des garnitures 61, une bague entretoise 62 percee et evidee, des gar- nitures 63 et 64, une bague entretoise 65 percee et evidee, des garnitures 66 et une bague de blocage 67 pleine, de diamMre prevu pour m:enager entre cette bague et la peri- ph6rie du piston une chambre annulaire 68. 30 A set of rings and linings whose purpose is to obtain the first leaktight sliding of the piston 50 in the first body 41, ie: a Bronze ring 58 ä. the upper part, ring comprising a hole 59 corresponding to the air inlet hole 60 practical in the body of the valve, gaskets 61, a spacer ring 62 drilled and hollowed out, gaskets 63 and 64, a spacer ring 65 pierced and hollowed out, fittings 66 and a solid blocking ring 67, of a diameter provided to form between this ring and the periphery of the piston an annular chamber 68.

40 Un chapeau 69 visse ä la Partie supe- rieure du corps et comprimant les garnitures par l'intermediaire de la bague 58 et servant d'ecrou ä la tige 56. Ce chapeau ne comporte pas d'orifice d'entree d'air. A bonnet 69 screws to the upper part of the body and compresses the seals through the intermediary of the ring 58 and serves as a nut for the rod 56. This bonnet does not have an air inlet orifice.

50 Un bouchon 70 qui est viss-e ä la Par tie inferieure du corps comprime les garni- tures 64 et 66 par l'intermediaire des ba- gues 65 et 67. Le fond du bouchon 70 est plan interieurement. Exterieurement, il fait saillie et est de forme h.exagonale en 71 pour permettre 1e vissage et 1e devissage. Les trous de vidange 72 sont disposes dans 1e fand du bouchon 70. A cap 70 which is screwed to the lower portion of the body compresses the gaskets 64 and 66 through rings 65 and 67. The bottom of the cap 70 is internally planar. Externally, it protrudes and is of h.exagonal shape at 71 to allow the first screwing and the first unscrewing. Drain holes 72 are located in the fand of cap 70.

Lorsque 1e piston se trouve dans la Posi tion la plus hasse correspondant ä Gelle de fermeture et vidange, la fermeture a lieu comme il a ete decrit pour 1'autre forme de realisation (fig. 1 ä 4). When the piston is in the lowest position corresponding to the closure and emptying valve, the closure takes place as described for the other embodiment (fig. 1 to 4).

La vidange s'opere du fait que 1'orific.e 43 relie ä la conduite de distribution est en communication avec 1'exterieur par 1'inter- m6diaire de la bague entretoise 65, des trous 54 du piston, de 1'evidement 52, des trous 55 de la chambre 68 situee entre 1e piston et la bague, 67 et des trous 72 du fand. The emptying takes place because the orifice 43 connected to the distribution pipe is in communication with the outside via the intermediary of the spacer ring 65, the holes 54 of the piston, the recess 52 , holes 55 of the chamber 68 located between the first piston and the ring, 67 and holes 72 of the fand.

Si 1'on deplace 1e piston de bas en haut par la manoeuvre de la tige 56, pour 1'amener dans la Position de fermeture du robinet (fig. 6), 1e piston 50 est deplace vers 1e haut et ses trous 54 et 55 se trouvent obtu- res par les garnitures 64 et 66. La commu- nication entre les orifices d'entree 42 et de sortie 43 est ainsi interceptee; il y a donc fermeture simple du robinet saus vidange. If the piston 50 is moved from bottom to top by operating the rod 56, to bring it into the valve closed position (fig. 6), the piston 50 is moved upwards and its holes 54 and 55 are closed off by gaskets 64 and 66. Communication between the inlet 42 and outlet 43 orifices is thus intercepted; there is therefore simple closure of the tap without emptying.

Pour ouvrir 1e robinet, an amene 1e piston dans sa Position la plus elevee, en maumu- vrant la tige 56 dans 1e meme sens que prF- cedemment. Dans cette Position, les orifices d'entree 42 et de sortie 43 sont en communi- cation, la vidange et la Prise d'air sont fer- rnees. L'eau entre par 1'orifice 42, se send dann 1'evidement 45 oü debouchent les trous 54 .du piston; eile penetre par lesdits trous dans 1'evidement 52 du piston, trouve Pas sage par les trous 55, traverse laRTIID="0004.0272" WI="10" HE="4" LX="1779" LY="731"> bague 65 par les trous que celle-en comporte et arrive ä 1'orifice de sortie 43. Tout se passe comme dans 1e mode de realisation des fig. 1 ä 4. To open the valve, one brings the piston to its highest position, moving the stem 56 in the same direction as before. In this Position, the inlet 42 and outlet 43 orifices are in communication, the drain and the Air Intake are closed. The water enters through the orifice 42, goes into the recess 45 where the holes 54 of the piston open; it enters through the said holes in the recess 52 of the piston, finds the passage through the holes 55, crosses the RTIID="0004.0272" WI="10" HE="4" LX="1779" LY="731"> ring 65 through the holes that it has and arrives at the outlet orifice 43. Everything happens as in the embodiment of FIGS. 1 to 4.
