AFK Stainless Steel 1/4inch 3/8inch 1/2inch Gas Safety Valve Industrial
Kufotokozera Kwazinthu za Gasi Safety Valve
gwirani ntchito
■ Pamene kupanikizika kwa dongosolo kumafika pazitsulo zokhazikika, valavu yotetezera imatsegulidwa, ndipo kupanikizika kwa dongosolo kumagwera pansi pa kupanikizika kokhazikitsidwa.
■ Kusankhidwa kwa ma valve otetezera ndikuyika kumakwirira kufunikira kokhazikitsa kukakamiza kuti akhazikitse kupanikizika, ndikuyika chizindikiro chofananira pachivundikiro cha kapu.
■ Kwa ma valve omwe sanagwiritsidwe ntchito kwa nthawi yayitali, kukakamiza koyambirira kwa kukweza koyambirira kungakhale kopambana kuposa kuyika.
■ Khazikitsani kukakamiza ndi kusindikizanso kukakamiza
Kuyika kuthamanga ndiko kuthamanga kwamtunda pamene pali madzimadzi kwa nthawi yoyamba.Pa kutentha kwapakati, katundu woyambayo akamaliza, kupanikizika kwa valve iliyonse kungathe kubwerezedwa mkati mwa ± 5%.
Kuthamanga kosindikizidwa ndiko kuthamanga kwamtunda pamene thupi loyenda likutuluka, ndipo kupanikizika kosindikizidwa kumakhala kocheperapo kusiyana ndi kukakamizidwa kokhazikitsidwa.
mayeso
Mndandanda uliwonse wa gawo la ma valve otsitsa katundu ayenera kuyesedwa mwa kukhazikitsa ntchito ndi kusindikizanso ntchito.
| Mndandanda | Kukhazikitsa kukakamiza kwa Test psig (bar) | Monga kukakamizidwa kocheperako kosindikiza kokhazikitsa peresenti yamphamvu % |

Tsatanetsatane wa Zogulitsa za Gasi Safety Valve
Kupanikizika kwa msana
■ Vavu yothamanga kwambiri (RVH)
Kupyolera mu kamangidwe ka ma valve okwera kwambiriwa, mphamvu ya dongosolo lakumbuyo lakumbuyo imachepetsedwa.
■ Valovu yotsika kwambiri (RV)
Kuthamanga kumbuyo kwa dongosolo kumawonjezera kupanikizika kwa valve.Kuti mupereke chipukuta misozi, chotsani zotsatira kuchokera ku 0.8 ndikuchotsa zotsatira zomwe zapezedwa kuchokera pakufunika kokhazikitsa.
Pamene kuthamanga kumbuyo kuli kofanana ndi kuthamanga kwa mumlengalenga, zotsatira zomwe zimapezedwa ndi ntchito zimakonzedweratu.
Mwachitsanzo: kukakamiza kokhazikitsidwa kofunikira ndi 120 PSIG.Kupanikizika kumbuyo kwa dongosolo ndi 40 PSIG.
Khwerero 1. Kuthamanga kumbuyo kumachulukitsidwa ndi 0.8.40 PSIG X 0.8 = 32 PSIG.
Khwerero 2. Chotsani zotsatira kuchokera pakufunika kokhazikika.120 PSIG -32 PSIG = 88 PSIG.
Khwerero 3. Konzani gawo la valve yolemetsa pa 88 PSIG.
Zithunzi za RVH

■ Zida zosindikizira zosiyanasiyana zilipo
■ Lembetsani kuchuluka kwa mphamvu yotsegulira
■ Pamene kukakamiza koyikirako kuli kotsika kuposa 1500PSig, mutha kusankha chogwirira chowongolera chapamwamba kwambiri.
Chogwirizira ichi chikhoza kutsegula valavu popanda kusintha kupanikizika konse
■ Kukula kwa mawonekedwe:
1/8 "mpaka 1/2", 3mm mpaka 12mm makadi apawiri
