Beschreibung
Zusammenfassung:	A sealing valve comprises a sealing valve body (1). The sealing valve body (1) is provided with a cylindrical valve hole (2), and a bottom end of the cylindrical valve hole (2) is provided with a frustum hole (3). The frustum hole (3) is arranged coaxially with the cylindrical valve hole (2), and a small bottom end of the frustum hole (3) is in communication with the bottom end of the cylindrical valve hole (2). The sealing valve is controllable over the opening and closing of a nozzle and can prevent crystallization of a liquid at the nozzle. L'invention concerne une soupape d'étanchéité comprenant un corps (1) de soupape d'étanchéité et un trou de soupape cylindrique (2) ménagé dans le corps (1) de soupape d'étanchéité, une extrémité inférieure du trou de soupape (2) étant pourvue d'un trou tronconique (3); le trou tronconique (3) est disposé de manière coaxiale avec le trou de soupape (2); et une extrémité du petit fond du trou tronconique (3) est en communication avec l'extrémité inférieure du trou de soupape (2). La soupape d'étanchéité facilite la commande de l'ouverture et de la fermeture d'une buse et peut empêcher la cristallisation d'un liquide dans la buse.
