Description

La présente invention concerne un robinet pour la prise en charge sur une conduite dans laquelle circule un fluide (eau ou gaz) sous pression. The present invention relates to a tap for taking over a pipe in which a fluid (water or gas) under pressure circulates.

Un robinet de ce type est notamment décrit dans les documents FR-A-2.560.663 et FR-A-2.576.663. Il comprend en particulier un corpus constitué d'une tubulure d'entrée qui est disposée sensiblement perpendiculairement à la conduite de fluide, une tubulure de service de même axe que cette tubulure d'entrée et une tubulure de sortie dont l'axe est sensiblement perpendiculaire à celui de la tubulure de service. A valve of this type is described in particular in documents FR-A-2,560,663 and FR-A-2,576,663. It comprises in particular a corpus consisting of an inlet pipe which is arranged substantially perpendicular to the fluid pipe, a service pipe of the same axis as this inlet pipe and an outlet pipe whose axis is substantially perpendicular to that of the service tubing.

La tubulure d'entrée a un diamètre intérieur inférieur à celui de la tubulure de service et s'arrête au droit de la tubulure de sortie qui débouche ainsi dans la tubulure de service.The inlet tubing has an inner diameter smaller than that of the service tubing and stops at the right of the outlet tubing which thus opens into the service tubing.

Une fois ce robinet disposé sur une conduite de fluide au layon d'un dispositif approprié tel que décrit par exemple dans les documents FR-A-2.536.828 et FR-A-2.625.289, on visse sur la tubulure de sortie un moyen d'obturation permettant d'obturer La tubulure d'entrée au niveau de son raccordement avec la tubulure de service. Once this tap has been placed on a fluid line with a suitable device as described for example in documents FR-A-2,536,828 and FR-A-2,625,289, a means is screwed onto the outlet pipe. shutter to shut off The inlet tubing at its connection with the service tubing.

Afin de percer la paroi de la conduite de fluide, on dispose dans la tubulure dc service un moyen perforant. In order to pierce the wall of the fluid line, there is a perforating means in the service tubing.

Une fois le trou effectué, on retire ce moyen perforant et on obture la tubulure d'entrée par le moyen d'obturation.Once the hole has been made, this perforating means is removed and the inlet pipe is closed by the sealing means.

Puis on dispose dans la tubulure de service une vanne qui permet d'obturer la tubulure d'entrée lorsque l'on retire le moyen d'obturation et que l'on raccorde la tubulure de sortie à une canalisation. La vanne permettra également de contrdler le débit de fluide traversant la tubulure d'entrée et la tubulure de sortie.Then a valve is placed in the service tubing which allows the inlet tubing to be closed when the closure means are removed and the outlet tubing is connected to a pipe. The valve will also control the flow of fluid through the inlet tubing and the outlet tubing.

Un tel robinet de l'art antérieur ne donne pas pleinement satisfaction notamment sur un plan strictement mécanique. D'une part, le corps de ce robinet comporte généra- lement des pièces mobiles conne décrit dans le document FR
A-2.625.829, et, d'autre part, la aise en place et La manoeu- vre de la vanne ne sont pas aisées et rapide. Such a tap of the prior art is not fully satisfactory, in particular on a strictly mechanical level. On the one hand, the body of this tap generally comprises movable cone parts described in the document FR
A-2.625.829, and, on the other hand, the ease in place and the operation of the valve are not easy and rapid.

Aussi un des buts de La présente invention estil de fournir un robinet pour la prise en charge d'une conduit de fluide, qui, bien que du genre decrit ci-dessus, ne comporte aucune pièce mobile. Also one of the objects of the present invention is to provide a valve for taking over a fluid conduit, which, although of the kind described above, has no moving parts.

Un autre but de l'invention est de fournir un tel robinet permettant d'assurer une fermeture sure et rapide de la tubulure d'entrée.  Another object of the invention is to provide such a valve making it possible to ensure safe and rapid closure of the inlet tubing.

Ces buts, ainsi que d'autres qui apparaStront par la suite, sont atteints par un robinet tel que décrit plus haut, qui est, selon la présente invention, caractérisé par le fait que la paroi interne de la tubulure de service qui est cylindrique, est munie de rampes hélicoidales disposées symétriquement et qu'il comprend également un obturateur constitué par un axe muni à une extrémité d'un moyen d'étan chéité- coopérant avec un siège constitué par le débouché de la tubulure d'entrée dans la tubulure de service- et à son autre extrémité d'un organe de manoeuvre, cet axe comportant un bloc, qu'il traverse selon un axe de symétrique, et qui est muni à sa périphérie de deux ergots inclinés, disposés symétriquement et pouvant coopérer avec les deux rampes héli- codales et cet axe traversant un capuchon obturant l'extrémi- té libre de ta tubulure de service, ce capuchon étant disposé entre le bloc et l'organe de manoeuvre. These aims, as well as others which will appear subsequently, are achieved by a tap as described above, which is, according to the present invention, characterized in that the internal wall of the service tube which is cylindrical, is provided with helical ramps arranged symmetrically and that it also comprises a shutter constituted by a pin provided at one end with a sealing means cooperating with a seat constituted by the outlet of the inlet pipe in the pipe service- and at its other end of an operating member, this axis comprising a block, which it crosses along an axis of symmetry, and which is provided at its periphery with two inclined lugs, arranged symmetrically and capable of cooperating with the two helical ramps and this axis passing through a cap sealing the free end of your service pipe, this cap being disposed between the block and the operating member.

De préférence, les rampes helicoidales s'ét-entent sur une demi-spire, et plus particulièrement de l'extrémité libre de la tubulure de service au débouché de la tubulure de sortie dans celle-ci
La description qui va suivre et qui ne présente aucun caractère limitatif, doit étire lue en regard de la figure unique en annexe qui représente en coupe verticale et partiellement en éclaté, un robinet de prise en charge selon la présente invention.Preferably, the helical ramps are ententent on a half-turn, and more particularly from the free end of the service tubing at the outlet of the outlet tubing therein
The description which follows and which does not have any limiting character, should be read with reference to the single figure in the appendix which represents in vertical section and partially in exploded view, a take-up tap according to the present invention.

Ainsi qu'on peut le voir sur cette figure, un robinet pour la prise en charge sur une conduite 1 dans laquelle circule un fluide (eau ou gaz) tous pression, est maintenu en position sur une telle conduite par un collier 2, par exemple.  As can be seen in this figure, a tap for taking over a pipe 1 in which a fluid (water or gas) circulates under all pressure, is held in position on such a pipe by a collar 2, for example .

Ce robinet comprend un corps 3 constitué d'une
tubulure d'entrée 4 qui est disposée sensiblement perpendicu
lairement à la conduite 1 avec laquelle elle communique, d'une tubulure de service 5 de meme axe que la tubulure d'en trée 4 et une tubulure de sortie 6 dont l'axe est sensiblement perpendiculaire à celui de la tubulure de service 5. La tubu
lure d'entrée 4 a un diamètre Intérieur inférieur à celui de la tubulure de service 5 et s'arrête au droit de la tubulure de sortie 6 qui débouche ainsi dans la tubulure de service 5 : il existe donc ainsi un siège 7. This tap comprises a body 3 consisting of a
inlet pipe 4 which is arranged substantially perpendicular
stretching to the pipe 1 with which it communicates, of a service pipe 5 of the same axis as the inlet pipe 4 and an outlet pipe 6 whose axis is substantially perpendicular to that of the service pipe 5. The tubu
lure inlet 4 has an inner diameter smaller than that of the service tubing 5 and stops at the right of the outlet tubing 6 which thus opens into the service tubing 5: there is thus a seat 7.

Selon la presente invention, la tubulure de service 5 est cylindrique et sa paroi interne comporte deux rampes hélicodales 8 qui sont disposées symétriquement et qui s'étendent sur environ une demi-spire depuis l'extrémité libre 16de la tubulure de service 5 jusqu'au débouché de la tubulure de sortie 6 dans celle-ci. Ces rampes sont terminées par un méplat 17 disposé dans un plan radial pour assurer le verrouillage positif du robinet en position de fermeture. According to the present invention, the service tubing 5 is cylindrical and its internal wall has two helical ramps 8 which are arranged symmetrically and which extend over approximately half a turn from the free end 16 of the service tubing 5 to outlet of the outlet pipe 6 therein. These ramps are terminated by a flat 17 disposed in a radial plane to ensure positive locking of the valve in the closed position.

Ce robinet comporte également un obturateur 9 qui est représenté en éclate sur la figure unique en annexe. This valve also includes a shutter 9 which is shown in bursts in the single figure in the appendix.

Cet obturateur 9 est consituté par un axe 10 qui est muni à une extrémité d'un moyen d'étanchéité Il qui coopérera avec le siège 7, et à son autre extrémité d'un organe de manoeuvre 12. Le moyen d'étanchéité est une rondelle sensiblement de meme diametre que le diamètre intérieur de la tubulure de service. Quant à l'organe de manoeuvre 12, il peut consister en un simple carre de manoeuvre comme représenté sur
la figure unique en annexe.This shutter 9 is constituted by an axis 10 which is provided at one end with a sealing means II which will cooperate with the seat 7, and at its other end with an operating member 12. The sealing means is a washer substantially the same diameter as the inside diameter of the service tubing. As for the operating member 12, it may consist of a simple operating square as shown in
the single figure in the appendix.

L'axe 10 comporte un bloc 13 qu'i I traverse selon un axe de symétrie et qui est muni à sa périphérie de deux ergots 14. Ceux-ci sont inclinés, disposés symétriquement par rapport à l'axe 10 sur le bloc 13 et coopèrent avec les rampes inclinées 8. The axis 10 comprises a block 13 which i I crosses along an axis of symmetry and which is provided at its periphery with two lugs 14. These are inclined, arranged symmetrically with respect to the axis 10 on the block 13 and cooperate with the inclined ramps 8.

L'obturateur. 9 comporte egalement un capuchon 15 qui est traversé en son centre par l'axe 10 et qui se visse sur l'extrémité libre 16 de latubulure de service 5 afin de permettre la mise en place et l-e maintien de l'obturateur 9. Ce capuchon 15 est dispose entre le bloc 13 et l'organe de manoeuvre 12.  The shutter. 9 also comprises a cap 15 which is traversed in its center by the axis 10 and which is screwed onto the free end 16 of the service tube 5 in order to allow the fitting and maintenance of the shutter 9. This cap 15 is arranged between the block 13 and the operating member 12.

Une fois l'obturateur 9 mis en place et fixé sur la tubulure de service 5, en faisant effectuer un quart de tour à l'organe de manoeuvre 12, on fait glisser les ergots 14 dans les rampes hélicoidales 8 correspondantes : ceci permet soit de mettre en contact le moyen d'étanchiété 11 avec son siège 7 et d'obturer ainsi la tubulure d'entrée 4, soit au contraire d'éloigner ce doyen d'étanchéité de son siège 7 et de mettre ainsi en communication la tubulure d'entrée 4 et la tubulure de sortie 6, permettant au fluide de s'échapper de la conduite 1.  Once the shutter 9 is in place and fixed on the service tube 5, by making the operating member 12 perform a quarter turn, the lugs 14 are slid into the corresponding helical ramps 8: this makes it possible either to bringing the sealing means 11 into contact with its seat 7 and thus closing off the inlet pipe 4, or on the contrary moving this sealing dean away from its seat 7 and thus putting the connection pipe into communication inlet 4 and outlet tubing 6, allowing fluid to escape from line 1.
