Ini membolehkan injap mengekalkan tekanan pembezaan yang malar merentasi peralatan (seperti penapis) atau melaraskan titik setnya dari jauh.<\/p>\n<\/li>\n<li>\n<p data-path-to-node=\"10,2,0\">Bahagian Dalaman Berprestasi Tinggi:<\/p>\n<ul data-path-to-node=\"10,2,1\">\n<li>\n<p data-path-to-node=\"10,2,1,0,0\">Tempat Duduk Logam: Dinilai untuk penutupan ANSI\/FCI Kelas IV.<\/p>\n<\/li>\n<li>\n<p data-path-to-node=\"10,2,1,1,0\">Tempat Duduk Elastomer: Dinilai untuk penutupan ANSI\/FCI Kelas VI, sesuai untuk aplikasi yang memerlukan penutupan kedap gelembung.<\/p>\n<\/li>\n<\/ul>\n<\/li>\n<li>\n<p data-path-to-node=\"10,3,0\">Kebolehgunaan Bahan: Pilihan badan terdiri daripada Besi Tuang Kelabu dan Keluli Karbon WCC hingga Keluli Tahan Karat CF8M\/CF3M, Monel dan Hastelloy C, memastikan keserasian dengan media menghakis atau suhu yang melampau.<\/p>\n<\/li>\n<\/ol>\n<hr data-path-to-node=\"11\" \/>\n<h2 data-path-to-node=\"12\">03 Prinsip Operasi<\/h2>\n<h3 data-path-to-node=\"13\">Tekanan Balik dan Kelegaan (MR98L\/H\/HH)<\/h3>\n<p data-path-to-node=\"14\">Injap-injap ini bertindak balas terhadap perubahan tekanan hulu. Tekanan direkodkan di bawah diafragma melalui port dalaman. Apabila tekanan hulu melebihi daya spring termampat, diafragma bergerak ke atas, mengangkat palam injap dari orifis. Ini membuka laluan aliran untuk melepaskan tekanan berlebihan.<\/p>\n<h3 data-path-to-node=\"15\">Pelepasan Pembezaan (Siri MR98D)<\/h3>\n<p data-path-to-node=\"16\">Model-model ini mengekalkan perbezaan tekanan malar antara tekanan terkawal dan tekanan pemuatan. Apabila tekanan pemuatan pada diafragma atas meningkat, ia menggerakkan palam injap lebih dekat ke orifis untuk menyekat aliran. Jika tekanan pemuatan berkurangan, palam akan bergerak menjauh, membolehkan aliran yang lebih tinggi mengekalkan \u0394P yang diperlukan.<\/p>\n<hr data-path-to-node=\"17\" \/>\n<h2 data-path-to-node=\"18\">04 Aplikasi Perindustrian Biasa<\/h2>\n<p data-path-to-node=\"19\">Yang <a href=\"https:\/\/www.yunrui-controls.com\/ms\/products\/fisher-mr98-series\/\">Siri Fisher MR98<\/a> adalah penting dalam sistem di mana pembendungan tekanan yang tepat merupakan keperluan keselamatan:<\/p>\n<ul data-path-to-node=\"20\">\n<li>\n<p data-path-to-node=\"20,0,0\">Sistem Bekalan Bahan Api: Mengekalkan tekanan balik yang berterusan dalam talian bahan api untuk pembakar, turbin dan enjin perindustrian yang besar.<\/p>\n<\/li>\n<li>\n<p data-path-to-node=\"20,1,0\">Pintasan Pam: Melindungi pam daripada terlalu panas dengan membenarkan peredaran semula apabila permintaan hiliran rendah.<\/p>\n<\/li>\n<li>\n<p data-path-to-node=\"20,2,0\">Perlindungan Penapis dan Penukar Haba: Menggunakan siri D untuk mencegah kerosakan yang disebabkan oleh penurunan tekanan yang berlebihan merentasi peralatan sensitif.<\/p>\n<\/li>\n<li>\n<p data-path-to-node=\"20,3,0\">Sistem Minyak Pelincir API: Menyediakan pelepasan tekanan lampau yang andal dalam sistem pelinciran untuk jentera berputar.<\/p>\n<\/li>\n<li>\n<p data-path-to-node=\"20,4,0\">Pensteril dan Autoklaf: Menguruskan perbezaan tekanan stim kritikal dalam loji farmaseutikal dan pemprosesan makanan.<\/p>\n<\/li>\n<\/ul>\n<hr data-path-to-node=\"21\" \/>\n<h2 data-path-to-node=\"22\">05 Perolehan dan Sokongan Teknikal<\/h2>\n<p data-path-to-node=\"23\">Pemilihan model yang betul untuk <a href=\"https:\/\/www.yunrui-controls.com\/ms\/products\/fisher-mr98-series\/\">Siri Fisher MR98<\/a> memerlukan pertimbangan yang teliti terhadap Pekali Aliran (Cv), julat spring dan keserasian bahan.
