شیر ایمنی صنعتی : شير ایمنی فشار يا PSV يكي از تجهيزات ايمني در صنعت است. كه مانع از قرار گرفتن لوله ها، شيرآلات، مخازن تحت فشار و… در شرايط فشاري بيش از فشار طراحي مي شود. بنابراين انتخاب PSV بسيار مهم بوده و بايد با احتياط كامل صورت پذيرد.
در انتخاب شیر ایمنی PSV و تعيين جزئيات آن چند سئوال مهم مطرح مي گردد:

چه نوع شیر ایمنی صنعتی براي فرآيند مورد نظر ما مناسب است؟

آيا روش ساده اي براي محاسبه سايز شیر ایمنی وجود دارد كه راحت تر از محاسبات دستي باشد؟

چه نوع متريالي برای شیر ایمنی بايد انتخاب گردد تا با شرايط فرآيندي مورد نظر هم خواني داشته باشد؟
قبل از پاسخ دادن به اين سوالات و نحوه انتخابPSV بهتر است با نحوه كار PSV آشنا شويم و آشنايي با قطعات اساسPSV به ما كمك خواهد كرد كه با آگاهي كامل اين انتخاب را انجام دهيم.

تعريف شير ایمنی فشار:

طبـق استـاندارد API 520 Part 1 كه به بررسي نحوه انتخاب، محاسبه سايز، نحوه نصب تجهيزات ایمنی در پالايشگاه ها مي پردازد. در مورد شير اطمينان تعريف زير ارائه شده است: يك شير ایمنی شيري است كه توسط يك فنر بسته شده است. و با رسيدن فشار پشت شير به يك فشار استاتيكي مشخص عمل كرده و به سرعت باز مي شود. (به اين عملPOP كردن شير مي گويند) شيرهاي ایمنی معمولاً براي سيالات تراكم پذير كاربرد دارد. با مشخص بودن مساحت سطح مجرابند و اندازه نازل مي توان مشخص نمود كه چه حجم سيال از شير خارج خواهد شد. در ابتدا بايد اندازه نازل خروجي (كه اُرفيس ناميده مي شود) محاسبه گردد.
