Kriyojenik K\u00fcresel Vanalar\u0131n Uzun Boyunlu Kaporta Gerektirmesinin Nedenleri<\/h2>\n\n\n\n

(1) Uzun boyunlu kapak, kriyojenik valfin salmastra kutusunu koruma i\u015flevine sahiptir, \u00e7\u00fcnk\u00fc salmastra kutusunun s\u0131zd\u0131rmazl\u0131\u011f\u0131, kriyojenik valfin anahtarlar\u0131ndan biridir. Salmastra kutusunda s\u0131z\u0131nt\u0131 olmas\u0131 so\u011futma etkisini azaltacak ve s\u0131v\u0131la\u015ft\u0131r\u0131lm\u0131\u015f gaz\u0131n gazla\u015fmas\u0131na yol a\u00e7acakt\u0131r.

Ortam s\u0131z\u0131nt\u0131s\u0131 sonucu dolgu maddesi olu\u015fur ve valf mili donar. Valf sap\u0131n\u0131n normal \u00e7al\u0131\u015fmas\u0131n\u0131 etkiler ve ayr\u0131ca valf sap\u0131n\u0131n yukar\u0131 a\u015fa\u011f\u0131 hareketinden kaynaklanan bulama\u00e7 dolgu maddesinin \u00e7izilmesi nedeniyle ciddi s\u0131z\u0131nt\u0131lara neden olur.
