China siyani valavu yogwira ntchito mwatsatanetsatane: kudula kapena kulumikiza njira yamadzimadzi

China kuyimitsa valavu ntchito mfundo mwatsatanetsatane: kudula kapena kulumikiza madzimadzi valavu Chinese globe valavu amagwiritsidwa ntchito kulamulira madzimadzi, mfundo yake yogwira ntchito ndi kuzindikira kulamulira madzimadzi potseka kapena kulumikiza njira madzimadzi. Nkhaniyi ikupatsani chidziwitso chatsatanetsatane cha momwe ma valve aku China amagwirira ntchito potengera akatswiri. 1. Momwe zimagwirira ntchito Ntchito yaikulu ya valve yoyimitsa ndikudula kapena kulumikiza njira yamadzimadzi mu payipi kuti muzitha kuyendetsa bwino komanso kuthamanga kwa madzi. Pamene valavu yaku China imatsekedwa, madzimadzi sangathe kudutsa mu valve; Vavu yaku China ikatsegulidwa, madzimadzi amatha kudutsa valavu. Mfundo yogwirira ntchito ya valve yaku China yapadziko lonse lapansi imatengera kapangidwe ka pisitoni kapena elevator. Pamene sing'anga (monga gasi kapena madzi) idutsa mu valve yoyimitsa ya ku China, kupanikizika kwa sing'anga kumapangitsa pisitoni kapena elevator kutsika pansi, zomwe zidzakanikiza kusindikiza pamwamba pa valavu kumbali zonse ziwiri za njira ndikuletsa kutuluka kwa sing'anga. Pamene kuli kofunikira kutsegula valavu, ingokwezani pisitoni kapena elevator m'mwamba kuti malo osindikizira asiye malekezero awiri a njirayo kuti ayambe kuyenda. 2. Gulu ndi makhalidwe Malingana ndi mapangidwe ndi ntchito zosiyanasiyana, ma valve a dziko la China akhoza kugawidwa mumtundu wowongoka, mtundu wa Angle, mtundu wa njira zitatu ndi mitundu ina. Mitundu yosiyanasiyana ya ma valve aku China ali ndi mawonekedwe osiyanasiyana komanso kuchuluka kwa ntchito. (1) Valavu yaku China yowongoka: Yowongoka kudzera mu valavu yaku China ndi mtundu womwe umagwiritsidwa ntchito kwambiri ndi valavu yaku China, yomwe ili ndi mawonekedwe osavuta, kupanga kosavuta komanso mtengo wotsika. Chowongoka chodutsa ku China valavu yapadziko lonse lapansi ndiyoyenera kutsika pang'ono, ntchito zazikulu zowongolera madzimadzi. (2) Angle Chinese globe valve: Angle Chinese globe valve ndi mtundu wamba wa valavu yaku China, mawonekedwe ake ndi ovuta kwambiri, koma amakhala ndi ntchito yabwino yosindikiza komanso kusintha. Angle Chinese globe valve ndiyoyenera kuthamanga kwambiri, ntchito zochepa zowongolera madzimadzi. (3) Valavu yapadziko lonse yaku China yanjira zitatu: Vavu yapadziko lonse ya China yanjira zitatu ndi mtundu wa valve wapadziko lonse wa China womwe ungagwiritsidwe ntchito kuwongolera mayendedwe atatu a njira yamadzimadzi. Valavu yapadziko lonse yachi China yanjira zitatu ndiyoyenera kugwiritsa ntchito pomwe njira zopitilira ziwiri zamadzimadzi ziyenera kuyendetsedwa nthawi imodzi. Mwachidule, mitundu yosiyanasiyana ya mavavu aku China ali ndi mawonekedwe osiyanasiyana komanso kuchuluka kwa ntchito, ndipo mtundu woyenera wa ma valve aku China uyenera kusankhidwa molingana ndi momwe amagwirira ntchito komanso zofunikira zogwiritsira ntchito. Ndikukhulupirira kuti mawu oyamba ankhaniyi atha kukupatsirani malangizo ndi chithandizo.
