La partie d'ouverture et de fermeture de la vanne \u00e0 soupape d'isolation thermique est un disque de soupape en forme de bouchon, la surface d'\u00e9tanch\u00e9it\u00e9 est plane ou conique, et le disque de soupape se d\u00e9place lin\u00e9airement le long de la ligne centrale du fluide. La forme de mouvement de la tige de soupape comprend un type \u00e0 tige montante (la tige de soupape monte et descend, et la roue \u00e0 main ne monte pas et ne descend pas), et il existe \u00e9galement un type \u00e0 tige rotative montante (la roue \u00e0 main tourne et monte avec la tige de soupape, et l'\u00e9crou est dispos\u00e9 sur le corps de la soupape). La vanne \u00e0 soupape \u00e0 soufflet ne convient que pour une ouverture et une fermeture compl\u00e8tes, aucun r\u00e9glage ni \u00e9tranglement n'est autoris\u00e9.<\/p>\n

 <\/p>\n

Principe de fonctionnement de la vanne \u00e0 soupape d'isolation thermique BJ45H :<\/p>\n

La vanne \u00e0 soupape d'isolation thermique est une vanne d'\u00e9tanch\u00e9it\u00e9 obligatoire, donc lorsque la vanne est ferm\u00e9e, une pression doit \u00eatre appliqu\u00e9e sur le disque de soupape pour forcer la surface d'\u00e9tanch\u00e9it\u00e9 \u00e0 ne pas fuir. Lorsque le fluide entre dans la vanne six par le dessous du disque de soupape, la r\u00e9sistance que la force de man\u0153uvre doit vaincre est la force de friction entre la tige de soupape et le garnissage, ainsi que la pouss\u00e9e g\u00e9n\u00e9r\u00e9e par la pression du fluide. La force de fermeture de la vanne est sup\u00e9rieure \u00e0 la force d'ouverture, le diam\u00e8tre de la tige de soupape doit donc \u00eatre important, sinon la d\u00e9faillance du sommet de la tige de soupape se produira. Ces derni\u00e8res ann\u00e9es, depuis l'apparition des vannes auto-\u00e9tanches, le sens d'\u00e9coulement du fluide de la vanne \u00e0 soupape d'isolation thermique a \u00e9t\u00e9 modifi\u00e9, passant du dessus du disque de soupape vers la cavit\u00e9 de la vanne. \u00c0 ce moment, sous l'action de la pression du fluide, la force de fermeture de la vanne est faible, tandis que la force d'ouverture est importante, et le diam\u00e8tre de la tige de soupape peut \u00eatre r\u00e9duit en cons\u00e9quence. Parall\u00e8lement, sous l'action du fluide, cette forme de vanne est \u00e9galement plus \u00e9tanche. Les \u201c Trois Chimies \u201d de mon pays stipulaient autrefois que le sens d'\u00e9coulement de la vanne \u00e0 soupape d'isolation thermique devait \u00eatre du haut vers le bas.<\/p>\n

Lorsque la vanne \u00e0 soupape d'isolation thermique est ouverte, lorsque la hauteur d'ouverture du disque de soupape est de 25 % \u00e0 30 % du diam\u00e8tre nominal, le d\u00e9bit atteint le maximum, indiquant que la vanne a atteint la position compl\u00e8tement ouverte. Par cons\u00e9quent, la position compl\u00e8tement ouverte de la vanne \u00e0 soupape doit \u00eatre d\u00e9termin\u00e9e par la course du disque de soupape.<\/p>\n

Domaine d'application de la vanne \u00e0 soupape d'isolation thermique BJ45H :<\/p>\n

La vanne \u00e0 soupape d'isolation thermique BJ45H convient aux pipelines des industries chimique et des engrais. La vapeur contenue dans la chemise peut emp\u00eacher le fluide de cristalliser.<\/p>\n
