Ia kemudian berpecah kepada dua laluan: satu ke ruang atas diafragma utama dan satu lagi ke salur masuk pandu.<\/p>\n<\/li>\n<li>\n<p data-path-to-node=\"7,1,0\">Respons Permintaan: Jika tekanan hilir jatuh di bawah tetapan spring pandu, diafragma pandu bergerak ke bawah, membuka injap pandu lebih lebar. Ini membolehkan tekanan pemuatan dikeluarkan ke hilir lebih cepat daripada yang boleh diisi semula oleh penyekat 112.<\/p>\n<\/li>\n<li>\n<p data-path-to-node=\"7,2,0\">Tindakan Injap Utama: Penurunan tekanan yang terhasil dalam ruang diafragma atas menyebabkan tekanan salur masuk (yang bertindak pada bahagian bawah diafragma) menolak palam injap ke atas, meningkatkan luas aliran untuk memulihkan tekanan yang ditetapkan.<\/p>\n<\/li>\n<li>\n<p data-path-to-node=\"7,3,0\">Tindak Balas Penutupan: Apabila tekanan hiliran meningkat, juruterbang menutup, meningkatkan tekanan di ruang atas dan memaksa palam injap utama ke bawah untuk mengurangkan aliran.<\/p>\n<\/li>\n<\/ol>\n<hr data-path-to-node=\"8\" \/>\n<h2 data-path-to-node=\"9\"><img decoding=\"async\" class=\"wp-image-8003 aligncenter\" src=\"https:\/\/www.yunrui-controls.com\/wp-content\/uploads\/2026\/04\/ezr1-300x169.webp\" alt=\"Buy genuine Fisher EZR regulators - China supplier Yunrui\" width=\"708\" height=\"399\" srcset=\"https:\/\/www.yunrui-controls.com\/wp-content\/uploads\/2026\/04\/ezr1-300x169.webp 300w, https:\/\/www.yunrui-controls.com\/wp-content\/uploads\/2026\/04\/ezr1-768x432.webp 768w, https:\/\/www.yunrui-controls.com\/wp-content\/uploads\/2026\/04\/ezr1-18x10.webp 18w, https:\/\/www.yunrui-controls.com\/wp-content\/uploads\/2026\/04\/ezr1.webp 888w\" sizes=\"(max-width: 708px) 100vw, 708px\" \/><br \/>\n02 Pentauliahan dan Pelarasan Juruterbang<\/h2>\n<p data-path-to-node=\"10\">Permulaan yang betul adalah penting untuk mencegah lonjakan tekanan.

Contohnya, komponen pemasangan diafragma dan palam mempunyai toleransi terma dan dimensi tertentu yang tidak dapat ditandingi oleh alat ganti pihak ketiga.
