Vavu ndiye chida chodziwika bwino m'mabizinesi amankhwala. Zikuwoneka zosavuta kukhazikitsa ma valve, koma ngati simutsatira teknoloji yoyenera, zidzayambitsa ngozi zachitetezo. Lero ndikufuna kugawana nanu zina zokhuza kukhazikitsa ma valve.
1. Mayeso a Hydrstatic pa kutentha koipa panthawi yomanga m'nyengo yozizira.
Zotsatira zake: chifukwa chubu limaundana mwachangu pakuyesa kwa hydraulic, chubucho chimazizira.
Miyezo: yesetsani kuyesa ma hydraulic mayeso asanayambe nyengo yachisanu, ndipo pambuyo poyesa kukakamiza kuwomba madzi, makamaka madzi mu valavu ayenera kuchotsedwa muukonde, apo ayi valavu idzachita dzimbiri, yolemetsa ndi yozizira. Ntchitoyi iyenera kuchitika m'nyengo yozizira, pansi pa kutentha kwamkati, ndipo madzi ayenera kuwombedwa pambuyo poyesa kukakamiza.
2, Kuyesa kwamphamvu kwa hydraulic system yamapaipi komanso kulimba, kuyang'anira kutayikira sikokwanira.
Zotsatira zake: kutayikira kumachitika pambuyo pa opaleshoni, zomwe zimakhudza kugwiritsa ntchito bwino.
Miyezo: Pamene dongosolo la mapaipi likuyesedwa malinga ndi zofunikira za mapangidwe ndi zomangamanga, kuwonjezera pa kujambula mtengo wa kuthamanga kapena kusintha kwa madzi mkati mwa nthawi yotchulidwa, makamaka fufuzani mosamala ngati pali vuto lotayira.
3, mbale ya butterfly valve flange yokhala ndi mbale wamba ya valve flange.
Zotsatira: gulugufe valavu flange mbale ndi wamba valavu flange mbale kukula ndi osiyana, ena flange m'mimba mwake ndi yaing'ono, ndi gulugufe valavu chimbale chachikulu, chifukwa osati lotseguka kapena molimba lotseguka ndi kupanga valavu kuwonongeka.
Miyezo: mbale ya flange iyenera kukonzedwa molingana ndi kukula kwenikweni kwa valavu ya butterfly.
4. Njira yopangira ma valve ndi yolakwika.
Mwachitsanzo: fufuzani valavu yamadzi (nthunzi) yoyenda yosiyana ndi chizindikiro, tsinde la valve limayikidwa pansi, valavu yoyang'ana yopingasa kuti mutenge kuikapo, kukwera kwa tsinde lachipata kapenavalavu yagulugufe yofewachogwirira sichikutsegula, pafupi ndi malo, etc.
Zotsatira zake: kulephera kwa valve, kukonza zosinthira kumakhala kovuta, ndipo shaft ya valve yomwe ikuyang'ana pansi nthawi zambiri imayambitsa kutuluka kwa madzi.
Miyezo: mosamalitsa malinga ndi malangizo a unsembe valavu unsembe, lotseguka ndodo chipata valavu kusunga valavu tsinde elongation kutsegula kutalika, gulugufe valavu mokwanira kuganizira chogwirira kasinthasintha danga, mitundu yonse ya tsinde valavu sangakhale pansi pa malo yopingasa, ngakhale pansi .
5. Mafotokozedwe ndi zitsanzo za valve yoyikidwa sizikugwirizana ndi zofunikira za mapangidwe.
Mwachitsanzo, kuthamanga kwadzina kwa valve kumakhala kochepa kusiyana ndi kuyesa kwa dongosolo; chakudya madzi nthambi chitoliro utenga ndivalve pachipatapamene chitoliro m'mimba mwake ndi zosakwana kapena wofanana 50mm; chitoliro choyamwa pampu yamoto chimatenga valavu ya butterfly.
Zotsatira: zimakhudza kutsegula ndi kutseka kwabwino kwa valve ndikusintha kukana, kupanikizika ndi ntchito zina. Ngakhale kuyambitsa ntchito ya dongosolo, kuwonongeka kwa valve kumakakamizika kukonzanso.
Miyezo: Dziwani bwino kuchuluka kwa mavavu osiyanasiyana, ndipo sankhani mawonekedwe ndi mitundu ya mavavu molingana ndi kapangidwe kake. Kuthamanga mwadzina kwa valve kudzakwaniritsa zofunikira za kupanikizika kwa dongosolo la kuyesa.
6. Vavu inversion
Zotsatira:chekeni valavu, valavu yochepetsera kupanikizika ndi ma valve ena ali ndi njira, ngati atayikidwa inverted, valve throttle idzakhudza zotsatira za utumiki ndi moyo; valavu yochepetsera kuthamanga sikugwira ntchito konse, valavu yoyang'ana ingayambitse ngozi.
Miyezo: valavu wamba, yokhala ndi chizindikiritso pathupi la valve; ngati ayi, ziyenera kudziwika bwino molingana ndi mfundo yogwirira ntchito ya valve. Vavu yachipata sayenera kutembenuzidwa (ndiko kuti, gudumu lamanja pansi), apo ayi zipangitsa kuti sing'angayo ikhalebe mu danga la boncover kwa nthawi yayitali, yosavuta kuwononga tsinde la valve, ndipo zimakhala zovuta kwambiri kuti zilowe m'malo modzaza. Ma valve okwera tsinde samayika pansi, apo ayi amawononga tsinde la valve chifukwa cha chinyezi.Chovala chowongolera cha swing, unsembe kuonetsetsa kuti pini kutsinde mlingo, kuti kusintha.
