Glob Vana Ak\u0131\u015f Y\u00f6n\u00fc<\/h2>\r\n\r\n\r\n\r\n\r\nGlob vanalar<\/a> neredeyse her sekt\u00f6rdeki \u015firketlerde en \u00e7ok kullan\u0131lan vanalardan biri haline gelmi\u015ftir.

Bu, ak\u0131\u015f ortam\u0131n\u0131n diskin alt\u0131ndan ge\u00e7ip \u00fcst\u00fcnden d\u0131\u015far\u0131 \u00e7\u0131kaca\u011f\u0131 anlam\u0131na gelir. K\u00fcresel vanalar genellikle zorunlu s\u0131zd\u0131rmazl\u0131k tasar\u0131m\u0131na sahiptir; bu nedenle vanan\u0131n kapat\u0131lmas\u0131, diski yuvaya do\u011fru bast\u0131ran bir bas\u0131n\u00e7 olu\u015fturur.

Bu, vanay\u0131 kapatmaya k\u0131yasla daha az kuvvet uygulaman\u0131z gerekti\u011fi anlam\u0131na gelir. Bu nedenle, milin b\u00fck\u00fclmesini \u00f6nlemek i\u00e7in mil \u00e7ap\u0131 daha b\u00fcy\u00fck olmal\u0131d\u0131r.

Son y\u0131llarda, vana bas\u0131n\u00e7 contalar\u0131 giderek yayg\u0131nla\u015fmaktad\u0131r; ak\u0131\u015fkan \u00fcst diskten alt diske do\u011fru ge\u00e7er, bu nedenle vanay\u0131 kapatma kuvveti, vanay\u0131 a\u00e7ma kuvvetinden daha azd\u0131r ve vana mili \u00e7ap\u0131n\u0131n daha k\u00fc\u00e7\u00fck olmas\u0131na izin verilir.\r\n\r\n\r\n\r\n\r\n\r\nAncak baz\u0131 g\u00f6r\u00fc\u015fler buna kat\u0131lmamaktad\u0131r, \u00f6zellikle daha b\u00fcy\u00fck boyutlu bir glob vana i\u00e7in (\u00f6rne\u011fin, DN250'den daha b\u00fcy\u00fck bir boyut), glob vana genellikle bir vana bas\u0131n\u00e7 contas\u0131 kullan\u0131r ve kapatma vanas\u0131 kuvveti g\u00f6z \u00f6n\u00fcne al\u0131nd\u0131\u011f\u0131nda, conta performans\u0131na ula\u015fmak kolayd\u0131r.
