Monga gawo lofunikira la mafakitale, kukhazikitsa koyenera ndikofunikira.Valve yoyikidwa bwino sikuti imangopangitsa kuti madzi aziyenda bwino, komanso amaonetsetsa kuti chitetezo ndi kudalirika kwa ntchito ya dongosolo.M'mafakitale akuluakulu, kuyika ma valve sikungofunika kuganizira zaukadaulo, komanso kutsata malamulo otetezedwa ndi miyezo yoyenera.Choncho, kufunikira kwa kukhazikitsa kolondola kwa ma valve sikungowoneka kokha pakuchita bwino ndi kukhazikika kwa kayendetsedwe ka kayendetsedwe kake, komanso chitetezo cha ogwira ntchito ndi zipangizo.Kupyolera mu kukhazikitsa kolondola, mavuto otuluka amatha kuchepetsedwa, kuyendetsa bwino kwadongosolo kumatha kusinthidwa, ngozi zamakampani zitha kupewedwa, chilengedwe ndi moyo wa antchito ndi katundu zitha kutetezedwa, potero kupereka chitetezo chodalirika pakupanga mafakitale.Choncho, kuyika bwino kwa ma valve ndikofunikira ndipo ndi chimodzi mwazinthu zofunikira kwambiri poonetsetsa kuti machitidwe a mafakitale akuyenda bwino.

1.Vavu yolowera.

Zotsatira: valve inverted, valve throttle valve, valve reduction valve, valve check valve ndi ma valve ena amawongolera, ngati inverted inverted, throttle idzakhudza ntchito ndi moyo;Ma valve ochepetsera kuthamanga sagwira ntchito konse, ndipo ma valve owunika amatha kubweretsa ngozi.

Miyezo: Ma valve ambiri, okhala ndi zizindikiro pa thupi la valve;Ngati sichoncho, chiyenera kudziwika bwino molingana ndi mfundo yogwirira ntchito ya valve.Chipinda cha valve cha valve yapadziko lonse ndi chosasinthika, ndipo madzi amadzimadzi ayenera kuloledwa kudutsa pa doko la valve kuchokera pansi mpaka pamwamba, kotero kuti kukana kwamadzimadzi kumakhala kochepa (kutsimikiziridwa ndi mawonekedwe), kutsegula ndikupulumutsa ntchito (chifukwa cha kupanikizika kwapakati kukwera), ndipo sing'angayo siimakakamiza kulongedza pambuyo potseka, yomwe ndi yosavuta kukonza.Ichi ndichifukwa chake valve yoyimitsa siyingatembenuzidwe.Osatembenuza valavu yachipata (ndiko kuti, gudumu lamanja pansi), apo ayi sing'angayo ikhalabe mu danga la valve kwa nthawi yaitali, yosavuta kuwononga tsinde la valve, ndipo ndizovuta pazinthu zina.Ndizovuta kwambiri kusintha kulongedza panthawi yomweyo.Tsegulani valavu yachipata, musakhazikitse pansi, apo ayi chifukwa cha chinyezi ndi dzimbiri zomwe zikuwonekera.Kwezani valavu cheke, unsembe kuonetsetsa kuti valavu chimbale ofukula, kuti Nyamulani kusintha.Swing cheke valavu, unsembe kuonetsetsa kuti pini mlingo, kuti kugwedezeka kusinthasintha.Valavu yochepetsera kuthamanga iyenera kuyikidwa molunjika pa chitoliro chopingasa, ndipo osapendekera mbali iliyonse.

Kuyika kwa 2.Valve musanayambe kuyang'anitsitsa khalidwe lofunika.

Zotsatira: Zingatsogolere ku kayendetsedwe ka kayendedwe ka valve sikusintha, kutsekedwa momasuka komanso kutuluka kwa madzi (gasi), zomwe zimapangitsa kukonzanso, komanso kukhudza madzi abwino (gasi).

Miyezo: Musanakhazikitse ma valve, kuyesa kwamphamvu ndi kulimba kuyenera kuchitidwa.Kuyesaku kudzachitika potengera 10% ya kuchuluka kwa gulu lililonse (giredi lomwelo, mawonekedwe omwewo, mtundu womwewo), osachepera imodzi.Kwa ma valve otsekedwa ozungulira omwe amaikidwa pa chitoliro chachikulu chomwe chimagwira ntchito yocheka, mayesero a mphamvu ndi zolimba ayenera kuchitidwa mmodzimmodzi.Mphamvu ya mavavu ndi kulimba koyezetsa kumayenera kutsatira malamulo ovomerezeka.

3.Butterfly valve flange yokhala ndi valavu wamba.

Zotsatira zake: kukula kwa valavu ya butterfly ndi yosiyana ndi flange wamba.Ma flanges ena amakhala ndi mainchesi ang'onoang'ono amkati, ndipo valavu ya butterfly ndi yayikulu, zomwe zimapangitsa kuti valavu isatsegule kapena kutsegula mwamphamvu.

Miyezo: Flange iyenera kukonzedwa molingana ndi kukula kwenikweni kwa valavu ya butterfly.
