The installaton ndi yofunika kwambiri pa ntchito ya ma valves a mpira wamkuwa, kuyika kosayenera kungayambitse kuwonongeka kwa ma valve ndi kusagwira ntchito kwa kayendedwe ka madzimadzi, Pano pali malangizo a Brass Ball Valve Installation.
Malangizo Azambiri
♦ Onetsetsani kuti ma valve ogwiritsidwa ntchito ndi oyenerera momwe angakhazikitsire (mtundu wa madzi, kuthamanga ndi kutentha).
♦ Onetsetsani kuti muli ndi mavavu okwanira kuti athe kusiyanitsa zigawo za mapaipi komanso zida zoyenera zokonzera ndi kukonza.
♦ Onetsetsani kuti ma valve oti ayikidwe ndi amphamvu zolondola kuti athe kuthandizira mphamvu ya kagwiritsidwe ntchito kawo.
♦ Kuyika mabwalo onse kuyenera kuwonetsetsa kuti ntchito yawo imatha kuyesedwa pafupipafupi (osachepera kawiri pachaka).

♦ Musanakhazikitse mavavu, yeretsani ndikuchotsa zinthu zilizonse pamapaipi(makamaka zitsulo zosindikizira ndi zitsulo), zomwe zimatha kutsekereza ndi kutsekereza ma valve.
♦ Onetsetsani kuti mapaipi onse olumikiza mbali zonse za valavu (kumtunda ndi pansi) akugwirizana (ngati si ma valve sangagwire bwino).
♦ Onetsetsani kuti zigawo ziwiri za chitoliro (kumtunda ndi kumtunda) zikugwirizana, gawo la valve silingatenge mipata iliyonse.Kusokoneza kulikonse mu mapaipi kungakhudze kulimba kwa kugwirizana, kugwira ntchito kwa valve ndipo kungayambitsenso kuphulika.
♦ Kunena zowona, ikani zida kuti zitsimikizire kuti kusonkhanitsa kukuyenda bwino.
♦ Musanayambe kukotcha, onetsetsani kuti ulusi ndi kuboola ndi zaudongo.
♦ Ngati zigawo za mapaipi alibe chithandizo chomaliza, ziyenera kukhazikitsidwa kwakanthawi.Izi ndi kupewa zovuta zosafunikira pa valve.
♦ Utali wamalingaliro operekedwa ndi ISO/R7 pakugunda nthawi zambiri ndi wautali kuposa momwe amafunikira, kutalika kwa ulusi kuyenera kukhala kochepa,ntchito Chithunzi cha PTFE kuonetsetsa kulimba kwa kukonza,ndionetsetsani kuti mapeto a chubu sakukankhira mpaka mutu wa ulusi.
♦ Ikani zitsulo za chitoliro kumbali zonse za valve.
♦ Ngati akukwera pa air conditioning ndi PER chubu ndi mapaipi, ndikofunika kuthandizira machubu ndi ma hoses ndi kukonza kuti valavu isavutike.
♦ Pamene mukugwedeza valavu, onetsetsani kuti mukuzungulira pambali yokhotakhota ndi mbali 6 yomwe ili kumapeto.Gwiritsani ntchito sipanela yotsegula kapena sipanela yosinthika osati sipini ya nyani.
♦ Musagwiritse ntchito vice kuti mumitse zokometsera za valve.
♦ Osalimbitsa kwambiri vavu.Osatsekereza ndi zowonjezera zilizonse chifukwa zingayambitse kuphulika kapena kufooketsa kwa casing.
♦ Nthawi zambiri, ma valve onse omwe amagwiritsidwa ntchito m'nyumba ndi kutenthetsa, musamangirire pamwamba pa torque ya 30 Nm.
Malangizo ndi malangizo a msonkhano pamwambapa sakugwirizana ndi chitsimikizo chilichonse.Zambiri zimaperekedwa mwachisawawa.Limanena zomwe siziyenera kuchitidwa.Zimaperekedwa kuti zitsimikizire chitetezo cha ogwira ntchito komanso kudalirika kwa ma valve.Malangizo amene ali m’zilembo zakuda atsatidwe.
