Abstract
Description
L'objet de l'invention concerne un dispositif d'extracteur flexible de garnitures tressées, de presse étoupe. The object of the invention relates to a flexible extractor device for braided linings, cable glands.
I1 est destiné à faciliter l'extraction des garnitures tressées, usagées dans toutes capacités boîtes à étoupe ou espaces d'accès difficiles. I1 is intended to facilitate the extraction of braided linings, used in all cable box capacities or difficult access spaces.
Il est connu d'utiliser des extracteurs de garnitures tressées de presse étoupe, constitués par une virole d'assemblage d ' un diamètre supérieur à 1 'hélicoTde d ' extraction ce qui rendait difficile ou impossible l'extraction des garnitures au fond de la boîte à étoupe, surtout lorsque la largeur de la boîte était inférieure au diamètre de la virole. Il en existait d'autres types comportant une hélicolde d'extraction vissée sur la virole ayant toujours tendance à se dévisser suivant les séries de traction ou d'accrochement. It is known to use extractors of braided stuffing box packings, constituted by an assembly ferrule with a diameter greater than the extraction helix which made it difficult or impossible to extract the linings from the bottom of the box. with cable, especially when the width of the box was less than the diameter of the ferrule. There were other types with an extraction helix screwed onto the shell which always tends to unscrew according to the series of traction or attachment.
Le dispositif suivant l'invention supprime ces inconvénients et permet d'obtenir la pénétration totale des boîtes à étoupe par l'ensemble hélicoide d'extraction et virole, tout en assurant une parfaite solidité de fixation non seulement de 1'hélicoïde sur la virole, mais encore de la tige flexible sur la virole et sur le manche de tenue. The device according to the invention eliminates these drawbacks and makes it possible to obtain total penetration of the cable boxes by the helical extraction and ferrule assembly, while ensuring perfect fixing solidity not only for the helicoid on the ferrule, but still flexible rod on the ferrule and on the holding handle.
Il est constitue par la combinaison d'une hélicoïde d'extraction ayant un diamètre supérieur ou le même diamètre que la virole d'assemblage soudée à l'étain ou brasée à l'argent sur 1 ' hélicoïde et la tige flexible, l'autre extrémité de la tige flexible est brasée en bout sur le manche de tenue. It is constituted by the combination of an extraction helicoid having a larger diameter or the same diameter as the assembly ferrule soldered in tin or silver brazed on one helicoid and the flexible rod, the other end of the flexible rod is brazed at the end onto the holding handle.
Sur le dessins annexé donné à titre d 'exemple non limitatif, d'une des formes de réalisation de ltobjet de l'invention, l'extrateur flexible de garnitures tressées de presse étoupe est représenté vu en élévation et en coupe longitudinale. In the appended drawings given by way of nonlimiting example, of one of the embodiments of the object of the invention, the flexible extractor of braided stuffing box packings is shown seen in elevation and in longitudinal section.
L 'hélic & de de pénétration 1 préférentiellement en acier spécial forgé et traité est assemblée sur la tige flexible 2 par la virole 3. The helix & penetration 1, preferably in special forged and treated steel, is assembled on the flexible rod 2 by the ferrule 3.
Cette virole à double logement 4, 5 en acier doux a un diamètre égal ou inférieur à celui de l'hélicotde 1. This mild steel ferrule 4, 5 has a diameter equal to or less than that of the helicoid 1.
L ' extrémité de 1 'hélicoide 6 est assemblée par soudure à l'étain ou brasure à l'argent à 1 ' intérieur du secteur 4. Le tout afin de donner un maximum de solidité à 1' assemblage tout en n'altérant pas les qualités de résistance de I'héiicoiide obtenues par traitement thermique. The end of the helicoid 6 is assembled by soldering with tin or silver soldering within the sector 4. The whole in order to give maximum solidity to the assembly while not altering the resistance qualities of heiicoid obtained by heat treatment.
L 'extrémité 7 de la tige flexible 2 est soudée à 1' s tain ou brasée à l'argent dans le secteur 5 de la virole, ce qui n ' amoindrit en aucune façon la résistance et la flexibilité des fils d'acier torsadés de la tige. The end 7 of the flexible rod 2 is welded to one tin or silver brazed in the sector 5 of the ferrule, which in no way reduces the strength and flexibility of the twisted steel wires of the stem.
Enfin, l'extrémité supérieure 8 de la tige flexible 2 est brasée dans l'orifice 9 du manche de tenue 10. Finally, the upper end 8 of the flexible rod 2 is brazed in the orifice 9 of the holding handle 10.
L 'hélicolde 1 pénétre dans la garniture à extraire par l'effet de rotation imprimé au manche de tenue 10 et transmis par la tige flexible 2. The helicoid 1 enters the lining to be extracted by the rotational effect printed on the holding handle 10 and transmitted by the flexible rod 2.
Sous cette impulsion, I 'hélicoTde 1 se visse dans les garnitures tressées dont l'extraction s'effectue par simple traction sur la tige. Under this impulse, I helicoTde 1 is screwed into the braided fittings whose extraction is carried out by simple traction on the rod.
La flexibilité de la tige et le diamètre réduit de la virole permettent d'accéder à 1' intérieur des boîtes à étoupe d'accès difficile, et à parois présentant des contre-dépouilles. The flexibility of the rod and the reduced diameter of the ferrule make it possible to access the interior of the stuffing boxes which are difficult to access, and with walls having undercuts.
Cet outil robuste et résistant à orientation omnidirectionnelle est utilisé pour toutes les applications industrielles et plus particulièrement par le personnel de maintenance des centrales thermiques, des raffineries, des machines marines sans limitation d ' emploi . This robust and resistant tool with omnidirectional orientation is used for all industrial applications and more particularly by the maintenance personnel of thermal power stations, refineries, marine machines without limitation of use.
Toutefois les formes, dimensions et dispositions des différents éléments pourront varier dans la limite des équivalents comme d ' ailleurs les matières utilisées pour leur fabrication sans changer pour cela, la conception générale de l'invention qui vient d'être décrite. However, the shapes, dimensions and arrangements of the various elements may vary within the limit of the equivalents, as indeed the materials used for their manufacture without changing the general design of the invention which has just been described.
