Abstract
Description
La présente invention concerne l'industrie électrotechnique et a, notamment, pour objet les soupapes d'un accumulateur étanche. The present invention relates to the electrotechnical industry and relates, in particular, to the valves of a sealed accumulator.
La présente invention peut être utilisée dans le domaine des sources chimiques de courant, de préférence, dans des accumulateurs étanches, pour la protection contre le manque d'étanchéité. The present invention can be used in the field of chemical sources of current, preferably in sealed accumulators, for protection against lack of tightness.
Le développement moderne des appareils radioélectriques portatifs de faible encombrement et des dispositifs électrotechniques de différentes destinations imposent des exigences plus sévères en ce qui concerne la fiabilité et la durée de vie des sources de courant, destinées à leur alimentation et, en particulier, la bonne étanchéité des accumulateurs. The modern development of portable radio devices of small size and electrotechnical devices of different destinations impose more stringent requirements as regards the reliability and the lifespan of the sources of current, intended for their supply and, in particular, the good sealing accumulators.
On connaît une soupape d'un accumulateur étanche (cf. brevet des Etats-Unis d'Amérique NO 3 293 081, classe 136-178, 1966) comportant une base faisant partie d'un couvercle de l'accumulateur étanche, un élément élastique, monté sur la base, et un couvercle dans lequel est pratiquée au moins une ouverture, lié mécaniquement à la base. La soupape en question comporte, en supplément, une rondelle logée à l'intérieur du couvercle et entourant l'élément élastique. La largeur de l'ouverture du couvercle dépasse le diamètre de l'éliment élastique. A valve of a sealed accumulator is known (cf. patent of the United States of America NO 3,293,081, class 136-178, 1966) comprising a base forming part of a lid of the sealed accumulator, an elastic element , mounted on the base, and a cover in which is formed at least one opening, mechanically linked to the base. The valve in question comprises, in addition, a washer housed inside the cover and surrounding the elastic element. The width of the lid opening exceeds the diameter of the elastic element.
Toutefois, dans cette soupape, le vieillissement du matériau du couvercle à la suite d'une utilisation de longue durée, aboutit à la variation de la pression qu'il exerce sur l'élément élastique et, par conséquent, à une baisse de la fiabilité de la soupape. However, in this valve, the aging of the material of the cover following a long-term use, results in the variation of the pressure which it exerts on the elastic element and, consequently, in a decrease of the reliability. of the valve.
De plus, le vieillissement de l'élément élastique de cette soupape baisse encore sa fiabilité. In addition, the aging of the elastic element of this valve further reduces its reliability.
On s'est donc proposé de mettre au point une soupape d'un accumulateur étanche, la largeur de ltou- verture du couvercle étant d'une valeur telle qu'elle permette d'augmenter sa fiabilité. It has therefore been proposed to develop a valve for a sealed accumulator, the width of the opening of the cover being of such a value that it makes it possible to increase its reliability.
Le problème posé est résolu du fait que la soupape d'un accumulateur étanche comportant une base faisant partie du couvercle de l'accumulateur étanche, un élément élastique monté sur la base et un couvercle, dans lequel est pratiquée au moins une ouverture, lié mécaniquement à la base, est caractérisée, selon l'invention, en ce que la largeur de l'ouverture de son couvercle constitue 70 à 90 % du diamètre de l'élément élastique. The problem is solved by the fact that the valve of a sealed accumulator comprising a base forming part of the lid of the sealed accumulator, an elastic element mounted on the base and a lid, in which is formed at least one opening, mechanically linked at the base, is characterized, according to the invention, in that the width of the opening of its cover constitutes 70 to 90% of the diameter of the elastic element.
La présente invention permet de remplacer l'élément élastique, ce qui élève la fiabilité de la soupape d'un accumulateur étanche. The present invention makes it possible to replace the elastic element, which increases the reliability of the valve of a sealed accumulator.
La présente invention simplifie également la conception de la soupape, ce qui permet d'élever davantage sa fiabilité. The present invention also simplifies the design of the valve, thereby further enhancing its reliability.
En outre, la présente invention permet de nettoyer la soupape en la débarrassant des carbonates, ce qui augmenta également sa fiabilité. In addition, the present invention makes it possible to clean the valve by ridding it of carbonates, which also increased its reliability.
La présente invention permet aussi de remplacer l'électrolyte dans l'accumulateur, ce qui augmente sa durée de vie. The present invention also makes it possible to replace the electrolyte in the accumulator, which increases its service life.
L'invention sera mieux comprise et d'autres buts, détails et avantages de celle-ci apparaîtront mieux, à la lumière de la description explicative qui va suivre d'un mode de réalisation donné uniquement à titre d'exemple non limitatif, avec références aux dessins non limitatifs annexés, dans lesquels
- la Figure 1 représente, en coupe longitudinale, une vue d'ensemble d'une soupape d'un accumulateur, selon l'invention,
- la Figure 2 est une vue de dessus de la Figure 1,
- la Figure 3 représente, en coupe longitudinale, une vue d'ensemble d'un accumulateur étanche selon l'invention, ayant deux ouvertures dans le couvercle,
- la Figure 4 est une vue de dessus sur la Figure 3.The invention will be better understood and other objects, details and advantages thereof will appear better, in the light of the explanatory description which follows of an embodiment given solely by way of nonlimiting example, with references to the accompanying non-limiting drawings, in which
FIG. 1 represents, in longitudinal section, an overall view of a valve of an accumulator, according to the invention,
- Figure 2 is a top view of Figure 1,
FIG. 3 represents, in longitudinal section, an overall view of a sealed accumulator according to the invention, having two openings in the cover,
- Figure 4 is a top view on Figure 3.
La soupape d'un accumulateur étanche comporte une base 1 (Figures 1, 2) faisant partie du couvercle 2 de l'accumulateur étanche (non montré sur le dessin). The valve of a sealed accumulator has a base 1 (Figures 1, 2) forming part of the cover 2 of the sealed accumulator (not shown in the drawing).
Un orifice de ventilation 3 est pratiqué au centre de la base 1. Un élément élastique 4 est monté sur la base 1 et est serré fortement contre ladite base par un couvercle 5, soudé au couvercle 2. Une ouverture 6, dont la largeur constitue 70 a 90 % du diamètre de l'élément élastique 4 et plus précisément 80 %, est pratiquée dans le couvercle 5.A ventilation opening 3 is made in the center of the base 1. An elastic element 4 is mounted on the base 1 and is tightened tightly against said base by a cover 5, welded to the cover 2. An opening 6, the width of which constitutes 70 at 90% of the diameter of the elastic element 4 and more precisely 80%, is made in the cover 5.
Selon l'autre mode de réalisation de la soupape de l'accumulateur étanche, le couvercle est exécuté sous forme d'un étrier 7 (Figures 3, 4). La largeur des ouvertures 8, 9, formées par les parois de l'étrier 7 et par la base 1 constitue 70 à 90 % du diamètre de l'élément élastique 4 et, plus précisément, 80 %. According to the other embodiment of the sealed accumulator valve, the cover is executed in the form of a stirrup 7 (Figures 3, 4). The width of the openings 8, 9, formed by the walls of the stirrup 7 and by the base 1 constitutes 70 to 90% of the diameter of the elastic element 4 and, more precisely, 80%.
La soupape de l'accumulateur étanche fonctionne de la manière suivante. The sealed accumulator valve operates as follows.
Sous l'effet d'une pression accrue de gaz transmise depuis l'accumulateur étanche a travers l'orifice de ventilation 3 (Figure 1), l'éliment élastique 4 (Figures 1, 2) se déforme et laisse échapper, a"' une pression déterminée, un excédent des gaz. En cas de changement des caractéristiques physiques et mécaniques de l'élément élastique 4 ou de dépôt de carbonates, on le retire à travers l'ouverture 6 dans le couvercle 5. On nettoie la base 1, en la débarrassant des carbonates et on remet en place l'élément élastique 4. Under the effect of an increased pressure of gas transmitted from the sealed accumulator through the ventilation orifice 3 (Figure 1), the elastic element 4 (Figures 1, 2) deforms and lets escape, a "' a determined pressure, an excess of gases. In the event of a change in the physical and mechanical characteristics of the elastic element 4 or of carbonate deposits, it is withdrawn through the opening 6 in the cover 5. The base 1 is cleaned, by removing the carbonates and replacing the elastic element 4.
En vue d'éviter les endommagements éventuels de l'élé- ment 4 pendant son montage dans la soupape, il faut que la largeur de l'ouverture 6 soit d'au moins 70 % du diamètre de l'élément 4 et ne dépasse pas 90 % de son diamètre. En effet, un élément 4, dont la dimension est supérieure a cette valeur, est maintenu faiblement par le couvercle 5 au moment de l'évacuation des gaz. In order to avoid possible damage to the element 4 during its mounting in the valve, the width of the opening 6 must be at least 70% of the diameter of the element 4 and must not exceed 90% of its diameter. Indeed, an element 4, the dimension of which is greater than this value, is weakly held by the cover 5 at the time of the evacuation of the gases.
