چکیده

شیرهای کنترلی اتوماتیک شکست خط به دلایل متعدد در مناطق صعب العبور و با توجه به نیاز پدافندی غیرعامل یا حفاظت از اکوسیستم روی خطوط انتقال گاز نصب می‌گردند. اثر مشخصه‌های قطر اوریفیس، فشار اولیه خط و نرخ افت فشار شکست خط بر اختلاف فشار تنظیمی شیر بصورت آزمایشگاهی با گاز نیتروژن بررسی شد. با افزایش نرخ افت فشار شکست یا کاهش قطر اوریفیس یا فشار اولیه خط، این اختلاف فشار افزایش می‌یابد. زمان دست‌یابی به اختلاف فشار تنظیمی، تخمین ‌زده شد. دیاگرام اختلاف فشار تنظیمی بدون‌بعد برحسب نرخ افت فشار بدون‌بعد در دامنه کارکرد شیر کنترلی اتوماتیک ارائه شد.
