Abstract

L'invention concerne une soupape pilote électromagnétique à base d'eau pour mines. Une cavité de soupape est formée dans un corps de soupape (1) ; un premier orifice (11), un deuxième orifice (12) et un troisième orifice (13) qui sont en communication avec la cavité de soupape sont formés dans le corps de soupape (1) ; un siège de soupape fendue (2) comprend un premier siège de soupape d'extrémité (21), un second siège de soupape d'extrémité (22) et un manchon de guidage (23) ; un premier trou traversant de liquide (211) est formé dans le premier siège de soupape d'extrémité (21) ; un deuxième trou traversant de liquide (221) est formé dans le second siège de soupape d'extrémité (22) ; un troisième trou traversant de liquide (231) et un quatrième trou traversant de liquide (232) sont formés dans le manchon de guidage (23) ; et un ensemble d'ouverture/fermeture (3) est approprié pour ouvrir et fermer le premier trou traversant de liquide (211) et le deuxième trou traversant de liquide (221), de telle sorte que l'état de raccordement entre le premier orifice (11) et le troisième orifice (13) est opposé à l'état de raccordement entre le deuxième orifice (12) et le troisième orifice (13). Le siège de soupape de la soupape pilote électromagnétique à base d'eau pour mines est composé de trois parties. Pendant le traitement et la production, des difficultés de traitement telles que des trous inclinés et des trous borgnes sont évitées, ce qui permet d'abaisser la difficulté de traitement et le coût de traitement et d'augmenter la fiabilité de la soupape pilote.
