Soxta po'latdan yasalgan valfni qurish va o'rnatishning asosiy nuqtalari
O'rnatish joyi, balandligi, kirish va chiqish yo'nalishi dizayn talablariga javob berishi kerak va ulanish mustahkam va qattiq bo'lishi kerak.
Izolyatsiya quvur liniyasiga o'rnatilgan turli xil qo'lda klapanlarning dastasi pastga tushmasligi kerak.
Valfni o'rnatishdan oldin vizual tekshirish o'tkazilishi kerak va valfning nom belgisi amaldagi milliy standart umumiy valf belgisi gb12220 qoidalariga mos kelishi kerak.Ish bosimi 1,0MPa dan yuqori bo'lgan va magistral quvurni uzib qo'yadigan valflar uchun o'rnatishdan oldin mustahkamlik va sızdırmazlık sinovlari o'tkazilishi kerak va ular faqat malakali bo'lganidan keyin foydalanish mumkin.
Quvvat sinovi paytida sinov bosimi nominal bosimdan 1,5 baravar ko'p bo'lishi kerak va davomiyligi 5 minutdan kam bo'lmasligi kerak.Agar oqish bo'lmasa, vana qobig'i va qadoqlash malakali bo'lishi kerak.Sızdırmazlık sinovi paytida sinov bosimi nominal bosimdan 1,1 barobar ko'p bo'lishi kerak;Sinov bosimi sinov muddati davomida GB50243 standarti talablariga javob berishi kerak va agar valf diskining muhrlangan yuzasida oqish bo'lmasa, u malakali hisoblanadi.
