Description
Compteur à gaz sec monosoufflet.
Dans les compteurs à gaz see monosoufflet usuels, l'action du gaz sur la membrane obturant chaque boîte à soupapes se traduit tantôt par un effort supplémenta-ire appuyant la, soupape sur son siège, tantôt par un effort tendant à éloigner la soupape de son siège.
Cette action, négligeable lorsque la pression de marche du compteur est faible, le gaz étant généralement distribué sous une pression ne dépassant pas 100 mm d'eau, ne 1'est plus lorsque le compteur fonctionne à haute pression.
La présente invention a pour but d'annu- ler l'effet indiqué, ci-dessus.
La figure unique du dessin annexé représente, t. titre d'exemple, une forme d'exé- cution de l'objet de l'invention.
1 est une boîte à soupape à double siège 2 et 3, 4 est la soupape, 5 sa tige, 6 est la nnem- brane de la soupape 7 est une deuxième mem- brane équilibreuse disposée, autant que pos sible, mais non obligatoirement, dans le plan de la première.
Les deux membranes 6 et 7 sont rendues solidaire- ; l'une de l'autre.
Leur surface et les dimensions des leviers qui les relient doivent être telles que les moments des efforts auxquels elles sont soumises s'équilibrent.
L'accouplement des deux membranes 6 et : 7 est réalisé au moyen d'un levier 8 oscil- lant autour d'un point fixe 9 et articulé, d'une part, en 10, sur la tige de soupape et, d'autre pa. rt, en 11, à une biellette 12 articulée sur la membrane 7.
La membrane 7 peut être remplacée d'une façon moins satisfaisante par un ressort compensateur placé soit directement sur la tige de soupape, soit sur un organe intermédiaire ou relais, comme la membrane 7 elle-même.
REVENDICATION :
Compteur à gaz z sec monosoufflet, carac- térisé par le fait qu'il possède un dispositif tel que l'action du gaz sur la membra. ne obturant chaque boîte à soupapes est équili- brée.
SOUS-REVENDICATIONS :
1. Compteur selon la revendication, caractérisé en ce que l'équilibrage de l'action du gaz est réalisé par une deuxième membrane reliée cinématiquement à la. première.
2. Compteur selon la revendication, carac térisé en ce que l'équillibrage de l'action du gaz est réalisé par un ressort agissant di rectement sur la tige de soupape.
3. Compteur selon la revendication, caractérisé en ce que l'équilibrage de l'action du gaz est réalisé par un ressort agissant sur un organe intermédiaire relié à cette tige.

Single-bellows dry gas meter.
In the usual single bellows gas meters, the action of the gas on the diaphragm closing each valve box results sometimes in an additional force pressing the valve on its seat, sometimes in an effort tending to move the valve away from its seat. seat.
This action, negligible when the operating pressure of the meter is low, the gas being generally distributed under a pressure not exceeding 100 mm of water, no longer 1 is when the meter is operating at high pressure.
The object of the present invention is to cancel the effect indicated above.
The single figure of the attached drawing represents, t. by way of example, one embodiment of the object of the invention.
1 is a double-seated valve box 2 and 3, 4 is the valve, 5 its stem, 6 is the nnem- brane of the valve 7 is a second balancing diaphragm arranged, as far as possible, but not necessarily, in the plane of the first.
The two membranes 6 and 7 are made integral; one from the other.
Their surface and the dimensions of the levers which connect them must be such that the moments of the forces to which they are subjected are balanced.
The two membranes 6 and: 7 are coupled by means of a lever 8 oscillating around a fixed point 9 and articulated, on the one hand, at 10, on the valve stem and, on the other hand pa. rt, at 11, to a link 12 articulated on the membrane 7.
The membrane 7 can be replaced in a less satisfactory manner by a compensating spring placed either directly on the valve stem, or on an intermediate member or relay, such as the membrane 7 itself.
CLAIM:
Single-bellows dry gas meter, characterized by the fact that it has a device such as the action of gas on the membrane. not sealing each valve box is balanced.
SUB-CLAIMS:
1. Meter according to claim, characterized in that the balancing of the action of the gas is achieved by a second membrane kinematically connected to the. first.
2. Meter according to claim, charac terized in that the balancing of the action of the gas is achieved by a spring acting directly on the valve stem.
3. Meter according to claim, characterized in that the balancing of the action of the gas is performed by a spring acting on an intermediate member connected to this rod.
