QISQA TA'RIFLARI
Sanoat nazorat qilish klapanining tuzilishi Umumiy qo'llanmalar uchun bitta o'rindiqni boshqarish klapanidan tashqari, qafas turini boshqarish klapani ikkinchi darajali nazorat valflari orasida ikkinchi o'rinda turadi. Turli xil talablarga binoan qafas bezaklarni loyihalashning ko'plab variantlari bilan bo'lishi mumkin, shu jumladan ko'p teshiklar, nosimmetrik derazalar, pastroq shovqin va boshqalar. Qafas dizayni eng yaxshi sozlash ko'rsatkichi va aniqligi bilan teng foizli oqim xarakteristikalari uchun mavjud. Balansli trim dizayni katta bosimning pasayishi uchun ko'proq barqarorlikni, aktuatordan kamroq tortishni, shovqinni pasayishini va texnik xizmat ko'rsatishni osonlashtiradi.
Turli xil trim dizayni bilan qafas boshqariladigan valflar asosiy oqim xususiyatlarini, shu jumladan chiziqli va teng foizni beradi.
