Onani Mitundu ya Vavu, Mapulogalamu ndi Zosankha Zosankha

Tiyeni tiwone mitundu yosiyanasiyana ya ma cheki ma valve ndikukambirana momwe amagwirira ntchito, momwe amagwiritsidwira ntchito, komanso momwe tingasankhire mtundu woyenera.
Machitidwe opangidwa kuti alole zofalitsa zamadzimadzi kuti ziyende munjira imodzi yokha nthawi zambiri zimakhala ndi ma valve oyendera.Zitsanzo za machitidwe oterowo zimaphatikizapo mapaipi amadzimadzi, kumene zinyalala zimatha kuyenda njira imodzi.Fufuzani ma valves amagwiritsidwanso ntchito komwe kubwerera kumbuyo kungayambitse kuwonongeka kwa zipangizo.Tisanayambe kupeza. mumitundu yosiyanasiyana yama valavu, ntchito, ndi zosankha, tiyeni timvetsetse momwe ma valavu amagwirira ntchito.
Valve yowunikira kapena valavu yowunikira ndi chipangizo chomwe chimalepheretsa kutuluka kwa madzi m'njira imodzi yokha.Chotsani ma valve ali ndi ma doko awiri, cholowera ndi chotulukira, ndipo amapangidwa kuti ateteze kutuluka kwa madzi m'machitidwe osiyanasiyana a mafakitale. fufuzani ma valve, ndipo amasiyana ndi makina omwe amachititsa kuti atsegule ndi kutseka. zimagwira, zoyendetsa kapena kulowererapo kwa anthu kuti zigwire ntchito moyenera.Zimakhala zotsika mtengo, zogwira mtima komanso zosavuta kuziyika.Ndiko kuti, valve yowunikira idzagwira ntchito pokhapokha ngati pali kusiyana kwapakati pakati pa kulowetsa ndi kutuluka.Kuthamanga kochepa kosiyana komwe dongosolo liyenera kupitirira. kuti valavu itsegulidwe imatchedwa "kuthamanga kwapang'onopang'ono."Malingana ndi mapangidwe ndi kukula kwake, mtengo wa kusweka uku kumasiyanasiyana ndi valve yowunikira.Valvu idzatseka pamene pali kupanikizika kwa msana kapena kuthamanga kwapamwamba kuposa Kutsekera kwa valve yotsekera kumasiyanasiyana malinga ndi kapangidwe kake, mwachitsanzo, valavu yoyang'ana mpira imakankhira mpira kumtunda kuti utseke. Kutseka kumeneku kungathenso kuthandizidwa ndi mphamvu yokoka kapena akasupe.
Monga tanenera kale, pali mitundu yambiri ya ma valve owunika, iliyonse yomwe imapangidwira ntchito yake yapadera. kukhala ndi akasupe, matupi a valve, ma discs ndi otsogolera.Pamene kulowetsedwa kolowera kumakhala kokwanira kuti kugonjetse kupanikizika kwapang'onopang'ono ndi mphamvu ya masika, imakankhira phokoso la valve, kutsegula dzenje ndikulola kuti madzi azidutsa mu valve. adzakankha kasupe ndi disc motsutsana ndi dzenje / orifice, kusindikiza valavu.Kuyenda kwaufupi ndi kasupe wothamanga mofulumira kumalola kuyankha mwamsanga panthawi yotseka.Mtundu wa valve uwu ukhoza kuikidwa molunjika kapena molunjika, mogwirizana ndi dongosolo, choncho ziyenera kuchotsedwa kwathunthu kuti ziwonedwe kapena kukonzedwa.Zotsatirazi ndi mitundu ina ya ma valve cheke:
Mitundu ina ya ma cheke ma valve ndi ma valve owunika padziko lonse lapansi, ma valve a butterfly/wafer check valves, ma valve apapazi, ndi ma valve oyendera duckbill.
Ma valve owunikira amagwiritsidwa ntchito pafupifupi m'mafakitale onse kumene madzi amadzimadzi amayenera kuyenda kumbali imodzi.Ma valvewa amagwiritsidwanso ntchito pazida zapakhomo monga makina ochapira ndi otsuka mbale.Malingana ndi mapangidwe ndi momwe amagwirira ntchito, ma valve owunika angagwiritsidwe ntchito pazinthu zotsatirazi. kugwiritsa ntchito:
Zina zomwe muyenera kuziganizira posankha valavu yowunika ndi izi: Kugwirizana kwa zinthu za valavu yoyendera ndi sing'anga yamadzimadzi.
Onetsetsani ma valve ndi zipangizo zodziwika bwino m'mafakitale omwe si otsika mtengo komanso odalirika, komanso osavuta kugwiritsa ntchito.Mukagula valavu yowunikira, onetsetsani kuti mukumvetsa zosowa zanu zapadera ndikuyang'ana njira zosankhidwa za valve.Komanso, onetsetsani kuti mukumvetsa kukhazikitsa zofunikira kuti mupewe zovuta zamayendedwe oyenda kapena kuwonongeka kwa makina anu chifukwa cha kuchuluka kwamphamvu.
Charles Kolstad wakhala ndi Tameson kuyambira 2017 ndipo akuchokera ku United States of America.Ali ndi digiri ya Mechanical Engineering kuchokera ku yunivesite ya St. Thomas, Minnesota, USA.Amagwira ntchito kutali pamene akuyenda ku Ulaya, Asia ndi America. amapita ku likulu la Tameson nthawi ndi nthawi kukakumana ndi mamembala atsopano ndikugwira ntchito kuofesi.
