Abstract

The invention relates to a live tap on the side of a pressurised pipeline of the type with a spherical turning member, equipped with a turning member 2 securely fastened to a manoeuvring member 6 of vertical axis driven occasionally from above, by means of a long-stemmed key. In order to prevent vertical forces which may arise during the use of the key from repercussing on the shut off system, the tap comprises a cap 12 equipped with driving means compatible with the long-stemmed manoeuvring key which is securely fastened to the manoeuvring member but rests on the body 1. Preferably contact is made by virtue of plane portions 13, 14 advantageously provided with a seal 15 made from antifriction material.

Description

La présente invention concerne un perfectionnement au robinet utilisé pour réaliser une prise en charge sur le côté d'une conduite sous pression. The present invention relates to an improvement to the tap used to provide support on the side of a pressure pipe.

Lorsque ce type de robinet est utilisé sur une conduite enterrée, la manoeuvre du tournant s'effectue au moyen d'une clé, munie d'une longue tige, qui s'emmanche sur le carré de l'organe de manoeuvre. When this type of valve is used on a buried pipe, the turning operation is carried out by means of a key, provided with a long rod, which is fitted on the square of the operating member.

L'utilisation de ce type de robinet n'est qu'occasion- nelle, mais il est fréquent qu'au cours de cette utilisation pour des travaux de branchement par exemple, l'application plus ou moins précise et plus ou moins douce de la longue clé sur l'organe de manoeuvre, engendre des efforts verticaux qui se repercu tent sur le système d'obturation constitué par le tournant sphérique et ses joints. The use of this type of tap is only occasional, but it is frequent that during this use for connection work for example, the more or less precise and more or less gentle application of the long key on the operating member, generates vertical forces which are reflected on the shutter system constituted by the ball and its joints.

L'invention vise à remédier à cet inconvénient en protégeant l'organe de manoeuvre et par là le système d'obturation. Selon l'invention le robinet comporte, reposant sur le corps du dit robinet et solidaire de l'organe de manoeuvre, un chapeau muni de moyens d'entrainement compatibles avec la clé de manoeuvre à longue tige. Plus particulièrement, la partie inférieure du chapeau, en forme d'embase plane circulaire, est en appui sur une surface plane correspondante, située à la partie supérieure du corps du robinet, autour de l'organe de manoeuvre. Il est solidaire de l'organe de manoeuvre en rotation d'une part, au moyen d'un emmanchement sur le carré de l'organe de manoeuvre et en translation d'autre part, au moyen d'une goupille traversant le chapeau et l'organe de manoeuvre. The invention aims to remedy this drawback by protecting the operating member and thereby the shutter system. According to the invention, the valve comprises, resting on the body of said valve and secured to the operating member, a cap provided with drive means compatible with the long-stem operating key. More particularly, the lower part of the cap, in the form of a circular flat base, is supported on a corresponding flat surface, located at the upper part of the valve body, around the operating member. It is integral with the operating member in rotation on the one hand, by means of a fitting on the square of the operating member and in translation on the other hand, by means of a pin passing through the cap and the operating device.

Dans ce type de robinet, la rotation du tournant peut nécessiter un couple non négligeable. Pour ne pas ajouter à ce couple, le chapeau selon lsinvention, est en appui sur le corps du robinet par l'intermédiaire d'un joint réalisé de préférence en matériau antifriction. Un joint du même type est disposé à l'intérieur du robinet, entre une collerette sur l'organe de manoeuvre et un épaulement sur le corps ; il permet en plus une absorption des surpressions et "coup de bélier" en cas de défectuosité des sièges du tournant. In this type of valve, the rotation of the turn may require a significant torque. In order not to add to this torque, the cap according to the invention rests on the body of the tap by means of a seal preferably made of anti-friction material. A seal of the same type is placed inside the tap, between a flange on the operating member and a shoulder on the body; it also allows absorption of overpressures and "water hammer" in the event of a defect in the turning seats.

D'autre part, la rotation du tournant de ce type de robinet est limitée à un quart de tour, Cette limitation est assurée, dans l'invention, par la présence d'ergots sur le chapeau, lesquels ergots viennent buter sur d'autres ergots solidaires du corps du robinet, à la périphérie de la surface plane d'appui. On the other hand, the rotation of the turn of this type of valve is limited to a quarter turn. This limitation is ensured, in the invention, by the presence of lugs on the cap, which lugs come up against other lugs integral with the valve body, at the periphery of the flat bearing surface.

Il est à noter également que la rotation de fermeture du tournant de ce type de robinet, peut s'effectuer dans les deux sens. Le chapeau, selon l'invention, comporte, à cet effet, deux logements perpendiculaires l'un par rapport à l'autre pour la mise en place de la goupille permettant ainsi, grâce à une disposition symétrique des ergots sur le chapeau et sur le corps, de changer le sens de rotation du tournant. It should also be noted that the closing rotation of the turning of this type of valve can be carried out in both directions. The cap according to the invention comprises, for this purpose, two housings perpendicular to one another for the positioning of the pin thus allowing, thanks to a symmetrical arrangement of the pins on the cap and on the body, to change the direction of rotation of the turn.

L'invention sera mieux comprise à l'aide de la description et du dessin annexé dans lequel le robinet à boisseau sphérique est représenté en coupe. The invention will be better understood using the description and the appended drawing in which the ball valve is shown in section.

Ce robinet est constitué d'un corps 1 en deux parties, qui enserrent un tournant 2 sphérique. Ce tournant 2 pivote autour d'un axe vertical 3, entre deux sièges 4 et 5, actionné par A l'organe de manoeuvre 6. Le robinet est destiné à être branché sur une conduite 7 en charge, esquissée sur le dessin, au moyen d'un collier 8 partiellement représenté sur lequel se visse le corps du robinet. Le procédé de branchement est connu et n'est pas l'objet de l'invention. L'organe de manoeuvre 6 comporte une collerette 9 en appui sur un épaulement à-l'intérieur du corps 1. This valve consists of a body 1 in two parts, which enclose a spherical turn 2. This turn 2 pivots around a vertical axis 3, between two seats 4 and 5, actuated by A the operating member 6. The tap is intended to be connected to a pipe 7 under load, sketched in the drawing, by means a collar 8 partially shown on which the valve body is screwed. The connection method is known and is not the subject of the invention. The operating member 6 comprises a flange 9 bearing on a shoulder inside the body 1.

Cet appui s'effectue par l'intermédiaire d'un joint 10 réalisé de préférence en matériau antifriction. Pendant les manoeuvres du tournant 2 ou en cas de défectuosité des sièges 4 et 5, les surpressions ou "coup de bélier" sont répercu tés sur le corps 1 par la collerette 9 de l'organe de manoeuvre 6, par l'intermédiaire du joint 10. L'organe de manoeuvre 6 comporte également au niveau de la partie cylindrique qui assure le guidage en rotation dans le corps 1, une gorge de logement d'un joint torique 11 pour l'étan- chéité entre l'extérieur et l'intérieur du corps 1. This support is effected by means of a seal 10 preferably made of anti-friction material. During the maneuvers of the turn 2 or in the event of a defect in the seats 4 and 5, the overpressures or "water hammer" are passed on to the body 1 by the flange 9 of the operating member 6, by means of the seal. 10. The operating member 6 also comprises, at the level of the cylindrical part which ensures the guiding in rotation in the body 1, a groove for housing an O-ring 11 for the seal between the outside and the inside the body 1.

L'organe de manoeuvre 6 émerge du corps 1 sous la forme d'un carré destiné à l'entrainement en rotation. Ce carré et la partie supérieure du corps 1 sont coiffés par un chapeau 12 centré sur l'axe général de rotation 3. La partie supérieure du chapeau 12 est destinée à recevoir la clé de manoeuvre, non représentée, et elle comporte à cet effet des moyens de liaison en rotation du genre carré en forme de tronc de pyramide par exemple. Le chapeau 12 est solidaire en rotation, de l'organe de manoeuvre 6 au moyen du carré d'entrainement du dit organe sur lequel il est emmanché et il repose sur le corps 1 du robinet. La partie inférieure du chapeau 12 forme une embase plane circulaire 13 prenant appui sur une surface plane circulaire 14 ménagée à la partie supérieure du corps 1 autour de l'organe de manoeuvre 6.Un joint 15 antifriction est disposé entre l'embase 13 du chapeau et le corps 1. Le chapeau 12 est également solidaire en translation de l'organe de manoeuvre 6 au moyen d'une goupille 16 qui traverse le chapeau 12 et le dit organe de manoeuvre. The operating member 6 emerges from the body 1 in the form of a square intended for rotational training. This square and the upper part of the body 1 are capped by a cap 12 centered on the general axis of rotation 3. The upper part of the cap 12 is intended to receive the operating key, not shown, and it includes for this purpose rotational connecting means of the square kind in the form of a pyramid trunk for example. The cap 12 is integral in rotation with the operating member 6 by means of the drive square of the said member on which it is fitted and it rests on the body 1 of the valve. The lower part of the cap 12 forms a circular flat base 13 bearing on a circular flat surface 14 formed in the upper part of the body 1 around the operating member 6. An anti-friction seal 15 is disposed between the base 13 of the hat and the body 1. The cap 12 is also integral in translation with the operating member 6 by means of a pin 16 which passes through the cap 12 and the said operating member.

La rotation du tournant de ce type de robinet étant limitée à un quart de tour, des ergots 17 disposés sous l'embase 13 du chapeau 12 viennent en butée sur des ergots 18 disposés a la partie supérieure du corps 1 autour de la surface plane circulaire 14. The rotation of the turn of this type of valve being limited to a quarter turn, lugs 17 arranged under the base 13 of the cap 12 come into abutment on lugs 18 disposed at the upper part of the body 1 around the circular flat surface 14.

Le chapeau se prolonge, à la partie inférieure de l'embase par une jupe 19 qui recouvre les ergots 17 et 18. The cap is extended at the lower part of the base by a skirt 19 which covers the pins 17 and 18.

Pour permettre de changer le sens de rotation de fermeture, par exemple, du tournant 2, le chapeau 12 peut comporter un deuxiè me logement de goupille, perpendiculaire au premier. Dans ce ces, les ergots 17 et 18, respectivement sur le chapeau 12 et le corps 1, sont disposés symétriquement.  To allow the direction of closing rotation to be changed, for example, of the turn 2, the cap 12 may include a second pin housing, perpendicular to the first. In this, the pins 17 and 18, respectively on the cap 12 and the body 1, are arranged symmetrically.
