Vavu yapadziko lonse ikugwira ntchito, mitundu yonse ya ma valve ayenera kukhala athunthu komanso osasunthika.Maboti pa flange ndi bulaketi ndizofunikira kwambiri.Ulusi uyenera kukhala wosasunthika ndipo palibe kumasula kumaloledwa.Kumanga nati pa handwheel, ngati atapezeka lotayirira ayenera kumangika mu nthawi, kuti asavale kugwirizana kapena kutaya handwheel ndi nameplate.Ngati gudumu lamanja la valavu yapadziko lonse latayika, sipikani yosinthika siyiloledwa kugwiritsidwa ntchito m'malo mwake ndipo iyenera kukhala ndi zida munthawi yake.Chovala cholongedza sichiloledwa kupotoza kapena kusakhala ndi chilolezo chotsitsa.Chophimba chotetezera chiyenera kuikidwa pa tsinde la valavu yapadziko lonse m'malo omwe amaipitsidwa mosavuta ndi mvula, matalala, fumbi, mchenga ndi dothi lina.Kuyeza kwa valve yapadziko lonse lapansi kumakhala kokwanira, kolondola komanso komveka bwino.Chosindikizira, kapu ndi zida za pneumatic za valve yapadziko lonse lapansi ziyenera kukhala zathunthu komanso zokhazikika.Osagogoda, kuyimirira kapena kuthandizira zinthu zolemetsa pa valve yapadziko lonse yomwe ikugwira ntchito;Ma valve opanda zitsulo ndi zitsulo zotayidwa, makamaka, zambiri zidzayimitsa valavu pa ntchito yokonza kupanga kuwotcherera musanayambe komanso itatha kukonza valavu, chifukwa valavu muutumiki wa ntchito zopanga imagwira ntchito yofunika kwambiri, yokonza mwadongosolo komanso moyenera. idzateteza valavu yoyenera, valavu kuti igwire ntchito bwino, ndikutalikitsa moyo wautumiki wa valve.Kukonza ma valve kungawoneke ngati kosavuta, koma sichoncho.Nthawi zambiri pamakhala mbali zina za ntchito zomwe zimanyalanyazidwa.
Choyamba, pamene valavu ya globe ikuwotcha, vuto la jekeseni wa girisi nthawi zambiri limanyalanyazidwa.Pambuyo podzaza mafuta, wogwiritsa ntchito amasankha njira yolumikizira valavu ndi mafuta ndikugwira ntchito yodzaza mafuta.Pali zinthu ziwiri: kumbali imodzi, kuchuluka kwa jakisoni wamafuta kumakhala kochepa, ndipo malo osindikizira amavala mwachangu chifukwa chosowa mafuta.Kumbali ina, jekeseni wambiri wamafuta, zomwe zimapangitsa kuti ziwonongeke.Palibe kuwerengera kolondola kwa mphamvu yosindikiza ya mavavu osiyanasiyana a globe malinga ndi mtundu ndi gulu la mavavu.Mphamvu yosindikiza imatha kuwerengedwa ndi kukula ndi gulu la valavu yodulidwa, ndiyeno jekeseni wokwanira wamafuta.
Chachiwiri, vuto la kupanikizika nthawi zambiri limanyalanyazidwa pamene valavu ya globe ikuwotcha.Pa ntchito ya jekeseni mafuta, kuthamanga kwa jekeseni wa mafuta kumasintha nthawi zonse ndi nsonga ndi zigwa.Kupsyinjika kumakhala kochepa kwambiri, chisindikizo chimatuluka kapena chimalephera, chiwongoladzanja chimakhala chokwera kwambiri, mafuta pakamwa amatsekedwa, mafuta mu chisindikizo amawumitsidwa kapena mphete yosindikizira imatsekedwa ndi mpira wa valve ndi mbale ya valve.Nthawi zambiri, mafuta akakhala otsika kwambiri, mafuta obaya amalowa pansi pachipinda cha valve, chomwe chimachitika m'mavavu ang'onoang'ono onunkhira.Ndipo kuthamanga kwamafuta ndikokwera kwambiri, kumbali imodzi, yang'anani mphuno yamafuta, ndikusintha ngati dzenje lamafuta latsekedwa;Kumbali ina ndikuwumitsa lipid, kugwiritsa ntchito madzi oyeretsera, kufewetsa mobwerezabwereza kulephera kwamafuta osindikizira, ndikulowetsa mafuta atsopano.Kuphatikiza apo, mtundu wosindikiza ndi zinthu zosindikizira zimakhudzanso kuthamanga kwamafuta.Mitundu yosiyanasiyana yosindikiza imakhala ndi kuthamanga kwamafuta kosiyanasiyana.Nthawi zambiri, mphamvu yamafuta a chisindikizo cholimba ndi yayikulu kuposa ya chisindikizo chofewa.Kukonza kuwerenga mpira nthawi zambiri kumakhala kotseguka, mikhalidwe yapadera imasankha kutseka kukonza.Mavavu ena sangakhale onse kuti atsegule malo.Valve yachipata iyenera kutsekedwa panthawi yokonza kuti mafutawo adzazidwa ndi groove yosindikiza pambali pa mphete yosindikiza.Ngati ili lotseguka, mafuta osindikizira amagwera mwachindunji mumsewu kapena chipinda cha valve, ndikuwononga.

Pambuyo pa kukhazikitsa, valve yapadziko lonse iyenera kuyang'aniridwa nthawi zonse.Zinthu zazikulu zoyendera ndi izi:
(1) kuvala kosindikiza pamwamba pa valve yapadziko lonse lapansi.
(2) Kuvala kwa ulusi wa trapezoidal wa tsinde ndi mtedza wa tsinde.
(3) Kaya kulongedza kwake kwachikale komanso kosavomerezeka.Ngati chawonongeka, chiyenera kusinthidwa panthawi yake.
(4) pambuyo pa kukonzanso ndi kusonkhanitsa valavu yapadziko lonse lapansi, kuyesa kosindikiza kumayenera kuchitidwa.

Nortech ndi m'modzi mwa otsogola opanga ma valve ku China omwe ali ndi chiphaso cha ISO9001.

Zogulitsa zazikulu:Valve ya Butterfly,Valve ya Mpira,Chipata cha Chipata,Onani Vavu,Globe Vavlve,Y-Strainers,Electric Acurator,Pneumatic Acurators .
