Abstract

الطلب يقدم صمام لمنع التدفق الغير مقصود الزائد عن الحد المتوقع للتدفق المستمر لحفظ المائع وللحماية من أضرار الغرق الناتج عن التدفق الغير مقصود دون الحاجة لحساسات الكترونية او أجهزة كهرو-ميكانيكية. تعتمد فكرة عمل الصمام على ضبطه على أكبر كمية مائع متوقع تدفقها باستمرارية ويمكن أعادة ضبطها وقتما شاء المستخدم فعند وصول التدفق المستمر لهذه القيمة يعطي إنذار مسبق قبل الغلق فان لم توجد استجابة فيتم الغلق الأتوماتيكي بعدها بفترة وجيزة. الصمام يحسب كمية المائع من بداية كل تدفق ويعيدها الى الصفر عند قطع التدفق بواسطة المستخدم طالما التدفق أقل من الحد الأكبر المضبوط عليه الصمام. كما يحتوي الصمام على نظام انذار (كمالي) لإصدار ضوء وصوت قبل الغلق الذاتي بفترة وجيزة وبعده حتى يعاد فتحه بواسطة المستخدم.
