La vanne pneumatique marche-arr\u00eat\u00a0<\/strong>\u00a0est aliment\u00e9 par un cylindre pour assurer sa fonction de commutation.<\/p>\n

 <\/p>\n

\"\"<\/p>\n

 <\/p>\n

En termes de structure, il n'y a pas de diff\u00e9rence significative entre le corps d'une vanne pneumatique tout ou rien et celui d'une vanne de commande \u00e9lectrique. La principale diff\u00e9rence r\u00e9side dans les forces motrices qui modifient la position de la vanne.<\/p>\n

 <\/p>\n

La vanne pneumatique tout ou rien est actionn\u00e9e par l'air de commande dans le circuit d'air, qui agit sur le cylindre de commande de la vanne. Cette pression pousse le piston \u00e0 se d\u00e9placer, entra\u00eenant le curseur qui modifie la position de la vanne.<\/p>\n

 <\/p>\n

En revanche, la vanne \u00e9lectrique de r\u00e9gulation de d\u00e9bit g\u00e9n\u00e8re une aspiration \u00e9lectromagn\u00e9tique par l'interm\u00e9diaire d'une bobine en spirale, qui entra\u00eene le curseur pour modifier la position du corps de la vanne.<\/p>\n

 <\/p>\n

\"\"<\/p>\n

 <\/p>\n

L'interrupteur pneumatique change de position en contr\u00f4lant l'air dans son cylindre pour cr\u00e9er une certaine pression. Cette pression pousse alors le piston et le coulisseau pour modifier la position de la vanne. Par cons\u00e9quent, la vitesse de commande r\u00e9elle est relativement lente.<\/p>\n

 <\/p>\n

En revanche, le vanne \u00e9lectrique de r\u00e9gulation de d\u00e9bit<\/a> g\u00e9n\u00e8re une force d'aspiration \u00e0 une vitesse relativement rapide. Par cons\u00e9quent, du point de vue de la vitesse de travail, la porte de commande \u00e0 interrupteur \u00e9lectrique fonctionne plus rapidement.<\/p>\n

 <\/p>\n

\"\"<\/p>\n

 <\/p>\n

En outre, le signal de commande connect\u00e9 \u00e0 l'interrupteur pneumatique de la porte de contr\u00f4le est un signal de pression. Ce signal doit \u00eatre raccord\u00e9 \u00e0 un tuyau et n\u00e9cessite un volume important.<\/p>\n

 <\/p>\n

En revanche, le signal de commande des vannes de commutation \u00e9lectriques est g\u00e9n\u00e9ralement un signal de courant. Ce signal peut \u00eatre connect\u00e9 par des fils, et il n'y a pas de piston de commande. Par cons\u00e9quent, le volume de la vanne de r\u00e9gulation \u00e9lectrique est plus petit que celui des vannes de r\u00e9gulation pneumatiques.<\/p>\n
