Elektr nazorat valfini o'rnatish printsipi:
1. Valfning o'rnatish joyi, balandligi va kirish va chiqish yo'nalishi yo'nalish dizayni talablariga javob berishi kerak va ulanish mustahkam va qattiq bo'lishi kerak.
2. Vana quvur liniyasiga turli xil uchlari bilan ulanishi mumkin. Eng muhim ulanish usullari tishli, gardishli va payvandlangan ulanishlardir. Flanj ulanganda, agar harorat 350 darajadan oshsa, murvat bilan shikastlanadi. Flanj va qistirmalarning tirqishini bo'shashtirish, yuqori haroratga chidamli murvat materialini tanlash kerak.
3. Visual inspection must be carried out before the valve is installed, and the nameplate of the valve should comply with the current international standard GB12220 "General Valve Mark". For the valve whose working pressure is greater than 1.0MPA and plays a role in cutting off the main pipe, the strength and tightness test shall be carried out, and it shall be used only after passing the test. Other valves may not be tested separately and will be tested in the system pressure test.
4. Quvvat sinovi vaqtida sinov bosimi nominal bosimdan 1,5 baravar ko'p, davomiyligi 5 minutdan kam emas, vana qobig'i va qadoqlash qochqinsiz bo'lishi kerak.
5. Sızdırmazlık sinovi paytida sinov bosimi 0.3mpa ni tashkil qiladi va sinov davomida sinov bosimi o'zgarishsiz qolishi kerak va vaqt 2-jadvaldagi qoidalarga muvofiq bo'lishi kerak. Valf diskining muhrlangan yuzasi oqish bo'lmasa, malakali hisoblanadi.
6. Nominal diametri: DN15-500
