En basit haliyle, bir vakum kelebek vanas\u0131<\/a> Bu, bilindik \u00e7eyrek d\u00f6n\u00fc\u015fl\u00fc vanan\u0131n modifiye edilmi\u015f bir versiyonudur, ancak bu \u00f6zellikle d\u00fc\u015f\u00fck bas\u0131n\u00e7ta \u00e7al\u0131\u015fan sistemler i\u00e7in tasarlanm\u0131\u015ft\u0131r.

Sorun, ayn\u0131 vanay\u0131 vakum hatt\u0131na takmaya \u00e7al\u0131\u015ft\u0131\u011f\u0131n\u0131zda ortaya \u00e7\u0131kar. Malzemeler gaz \u00e7\u0131karmaya ba\u015flar, contalar gev\u015fer ve vana, vakum sisteminin gerektirdi\u011fi \u015fekilde bas\u0131nc\u0131 tutamaz.<\/p>\n\n\n\n

Bu nedenle kelebek tipi vakum vanalar\u0131 devreye girdi. Bunlar da ayn\u0131 d\u00f6nen disk fikrine dayan\u0131yor, ancak par\u00e7alar\u0131 d\u00fc\u015f\u00fck bas\u0131n\u00e7 fizi\u011fine uygun hale getirilmi\u015f durumda. <\/p>\n\n\n\n

Vakum ortam\u0131nda, k\u0131lcal bir bo\u015fluk bile s\u0131z\u0131nt\u0131 yolu haline gelir. \u0130zolasyonun h\u0131zl\u0131 bir \u015fekilde ger\u00e7ekle\u015fmesi de gerekir, bu nedenle bu vanalar h\u0131zl\u0131 a\u00e7\u0131l\u0131p kapanacak \u015fekilde tasarlanm\u0131\u015ft\u0131r. Tamamen a\u00e7\u0131k oldu\u011funda, disk ak\u0131\u015f\u0131 neredeyse hi\u00e7 engellemez, bu da pompan\u0131n hazneyi \u00e7ok daha h\u0131zl\u0131 bir \u015fekilde a\u015fa\u011f\u0131 \u00e7ekebilece\u011fi anlam\u0131na gelir.<\/p>\n\n\n\n

Ger\u00e7ekten \u00d6nemli Olan Farklar<\/h2>\n\n\n\n

S\u0131radan bir vana ile vakum uygulamalar\u0131na uygun bir vana aras\u0131ndaki ger\u00e7ek fark, kullan\u0131lan malzemelerde ve s\u0131zd\u0131rmazl\u0131k y\u00fczeylerinin nas\u0131l yap\u0131ld\u0131\u011f\u0131nda gizlidir.<\/p>\n\n\n\n
