Description

DISPOSITIF DE FIXATION
DE LA TUBULURE D'ADMISSION D'UNE VANNE OU VALVE
A UNE PIECE TUBULAIRE AU MOYEN D'UN ECROU
L'invention concerne un dispositif de fixation, pour fixer la tubulure d'admission d'une vanne ou valve à une pièce tubulaire portant un filetage mâle, au moyen d'un écrou de raccordement coiffant un collet de la tubulure d'admission par un épaulement circulaire.FIXING DEVICE
OF THE INLET TUBE OF A VALVE OR VALVE
TO A TUBULAR PART BY MEANS OF A NUT
The invention relates to a fixing device, for fixing the intake manifold of a valve or valve to a tubular part carrying a male thread, by means of a connection nut capping a collar of the intake manifold by a circular shoulder.

Avec un dispositif connu de ce genre (brevet DE 30 14 427), on rencontre des difficultés lors de la mise en place de l'écrou de raccordement sur la tubulure d'admission de la vanne ou valve munie d'un collet. Si les tolérances de l'ouverture d'entrée de l'écrou de raccordement par rapport à la largeur du collet ou au diamètre de la tubulure d'admission sont trop grandes, il y a alors un risque de positionnement erroné de l'écrou et de défaut d'étanchéité entre la tubulure d'admission et la pièce tubulaire, par exemple, d'un robinet d'arrêt. With a known device of this kind (patent DE 30 14 427), difficulties are encountered when fitting the connection nut onto the intake manifold of the valve or valve provided with a collar. If the tolerances of the inlet opening of the connection nut in relation to the width of the collar or the diameter of the intake manifold are too large, there is a risk of incorrect positioning of the nut and leakage between the intake manifold and the tubular part, for example, of a shut-off valve.

L'invention a pour but d'améliorer la forme de réalisation connue et, avec des moyens simples, de faciliter la mise en place de l'écrou de raccordement sur la tubulure d'admission de la vanne, en réalisant un agencement mutuel correct entre l'écrou de raccordement et le collet de la tubulure d'admission. The invention aims to improve the known embodiment and, with simple means, to facilitate the installation of the connecting nut on the inlet manifold of the valve, by achieving a correct mutual arrangement between the connection nut and the collar of the intake manifold.

Selon l'invention, ce but est atteint par le fait que l'écrou de raccordement consiste en une partie inférieure en forme de cuvette annulaire coiffant le collet de la tubulure d'admission du côté vanne ou valve, et en une #partie supérieure qui peut être vissée dans un tronçon fileté, en forme de manchon, de la partie inférieure, cette partie supérieure étant destinée à être fixée à la pièce tubulaire, à un robinet d'arrêt ou analogue, et par le fait qu'une bague d'appui constituée de deux demi-bagues est agencée entre le collet de la tubulure d'admission et le fond annulaire de la partie inférieure et prend appui contre ce fond annulaire et ce collet. According to the invention, this object is achieved by the fact that the connection nut consists of a lower part in the form of an annular bowl covering the collar of the intake manifold on the valve or valve side, and in an upper part which can be screwed into a threaded, sleeve-shaped section of the lower part, this upper part being intended to be fixed to the tubular part, to a stopcock or the like, and by the fact that a ring support consisting of two half-rings is arranged between the collar of the intake manifold and the annular bottom of the lower part and bears against this annular bottom and this collar.

L'invention prévoit en outre que les demi-bagues constituant la bague d'appui présentent des saillants pénétrant dans le trou de la partie inférieure et s'appliquant à la manière de coquilles contre la tubulure d'admission, et présentent des parties formant rebord qui s'appliquent contre le fond annulaire de la partie inférieure et contre le collet. The invention further provides that the half-rings constituting the support ring have projections penetrating into the hole in the lower part and applying in the manner of shells against the intake manifold, and have parts forming flange which are applied against the annular bottom of the lower part and against the collar.

La partie supérieure de l'écrou de raccordement vissée dans la partie inférieure peut entourer les parties formant rebord des demi-bagues constituant la bague d'appui, et immobiliser cette dernière contre la tubulure d'admission. Les demi-bagues constituant la bague d'appui peuvent avantageusement être en métal. The upper part of the connection nut screwed into the lower part can surround the flange parts of the half-rings constituting the support ring, and immobilize the latter against the intake manifold. The half-rings constituting the support ring can advantageously be made of metal.

Lors du montage de l'écrou de raccordement sur la tubulure d'admission de la vanne, la partie inférieure en forme de cuvette annulaire est d'abord passée, par son trou à grande tolérance, par-dessus le collet de la tubulure d'admission. Ensuite, les deux demi-bagues de la bague d'appui sont mises en place, et la partie supérieure est vissée dans la partie inferieure de l'écrou de raccordement. When mounting the connecting nut on the valve inlet manifold, the lower part in the form of an annular bowl is first passed, through its hole with great tolerance, over the collar of the manifold. admission. Then, the two half-rings of the support ring are put in place, and the upper part is screwed into the lower part of the connection nut.

Les caractéristiques et avantages de l'invention apparaîtront plus complètement à l'aide de la description d'un exemple non limitatif présenté ci-après en se reportant au dessin annexé, sur lequel
- la figure 1 est une vue en coupe montrant l'écrou de raccordement placé sur une tubulure d'admission d'une vanne ou valve non représentée;

Le dispositif représenté dans cet exemple est prévu pour fixer une tubulure d'admission 1 d'une vanne contre un tronçon tubulaire ou un robinet d'arrêt portant un filetage mâle. Ce dispositif consiste en un écrou de-raccordement en deux parties, 2 et 3, en métal et/ou matière plastique. La partie inférieure 2 de l'écrou de raccordement, qui peut être passée par-dessus un collet, un élargissement, ou analogue, de la tubulure d'admission 1, est en forme de cuvette annulaire et présente un trou 6 dans son fond annulaire 5. Dans cet exemple, le tronçon 7 en forme de manchon de la partie inférieure porte un filetage intérieur dans lequel peut être vissée une pièce filetée 8 correspondante appartenant à la partie supérieure 3 de l'écrou de raccordement. The device shown in this example is intended to fix an inlet pipe 1 of a valve against a tubular section or a stop valve carrying a male thread. This device consists of a connection nut in two parts, 2 and 3, made of metal and / or plastic. The lower part 2 of the connection nut, which can be passed over a collar, a widening, or the like, of the intake manifold 1, is in the form of an annular bowl and has a hole 6 in its annular bottom 5. In this example, the sleeve-shaped section 7 of the lower part carries an internal thread into which a corresponding threaded part 8 belonging to the upper part 3 of the connection nut can be screwed.

Entre le collet 4 de la tubulure d'admission 1 et le fond annulaire 5 de la partie inférieure est disposée une bague d'appui constituée de deux demi-bagues 9. Between the collar 4 of the intake manifold 1 and the annular bottom 5 of the lower part is a support ring made up of two half-rings 9.

Après avoir placé la partie inférieure par-dessus la tubulure d'admission, on introduit les demi-bagues dans la partie inférieure, de façon qu'elles s'appliquent à la manière de coquilles contre la tubulure d'admission, et soient engagées dans le trou 6 de la partie inférieure- par des saillants 10. En outre, -par des parties formant rebord il, les demi-bagues g s'appliquent par le dessous contre le collet 4 de la tubulure d'admission. After placing the lower part over the intake manifold, the half-rings are introduced into the lower part, so that they apply in the manner of shells against the intake manifold, and are engaged in the hole 6 in the lower part- by projections 10. In addition, -by parts forming a rim there, the half-rings g are applied from below against the collar 4 of the intake manifold.

Lorsque la partie supérieure 3 est vissée dans la partie inférieure 2, sa partie filetée 8 entoure les demi-bagues 9 formant la bague d'appui qu'elle maintient dans une position fixe prédéterminée. La référence 12 désigne une rondelle d'étanchéité et la référence 13 désigne un filetage intérieur de la partie supérieure 3 de l'écrou de raccordement, pour fixation à un robinet d'arrêt non représenté.  When the upper part 3 is screwed into the lower part 2, its threaded part 8 surrounds the half-rings 9 forming the support ring which it maintains in a predetermined fixed position. The reference 12 designates a sealing washer and the reference 13 designates an internal thread of the upper part 3 of the connection nut, for attachment to a stop valve not shown.
