Valve yowongolerambiri yachitukuko yowongolera mfundo zoyika ma valve achidule achidule
1. Kupanga ma valve oyendetsa kumagwirizana kwambiri ndi chitukuko cha njira zopangira mafakitale.
Kale, pofuna kuti madzi aziyenda bwino m’mitsinje kapena m’mitsinje, anthu ankagwiritsa ntchito miyala ikuluikulu kapena mitengo ikuluikulu kuletsa kutuluka kwa madzi kapena kusintha kumene madzi akupita.
Chitukuko cha Aigupto ndi Chigiriki chinapanga mitundu ingapo yakale ya valve, yomwe imagwiritsidwa ntchito pa ulimi wothirira mbewu, mwa zina.
Komabe, ambiri amavomereza kuti Aroma akale adapanga njira yamadzi yothirira mbewu mwaukadaulo kwambiri, yokhala ndi mapulagi ndi mavavu opangira ma cheke komanso kugwiritsa ntchito ma valavu otchinga kuti madzi asayende mozungulira.
Panthawi ya Renaissance, ojambula ndi oyambitsa. LeonardodaVinc adapanga ma valve opangira ngalande, ntchito zothirira ndi makina ena akuluakulu a hydraulic, ndipo mayankho ake ambiri akadalipo lero.
Mbiri yamakono ya mafakitale a valve yayendera limodzi ndi mafakitale. Ndi kupita patsogolo kwa mafakitale, ThomasNewcomen adapanga injini ya nthunzi yamafakitale ndi desiki yakutsogolo mu 1705, zomwe zimafuna kuwongolera magwiridwe antchito a injini ya nthunzi. JamesWatt adapanga chowongolera chosinthira liwiro ndi desiki yakutsogolo. Anthu ochulukirachulukira amalabadira kuwongolera kwamadzimadzi.
Woyang'anira wakale kwambiri anali wowongolera mpope wopangidwa ndi WilliamFisher mu 1880. Anali wodzidalira yekha ndi nyundo yolemera. Pamene kupanikizika kumbuyo kwa valve kunawonjezeka, kutsegulidwa kwa olamulira kunachepetsedwa pansi pa zochita za nyundo yolemera, kuti akwaniritse zotsatira zoyendetsera mphamvu zokhazikika.
M'zaka za m'ma 1930 mpaka zaka za m'ma 1930, mawonekedwe a ma valve ozungulira a valavu yozungulira (b>

Mu 70's valavu yowongolera manja imagwiritsidwa ntchito kwambiri pakuwongolera njira zopangira mafakitale, ma eccentric rotary valve opangidwa ndi eccentricplugv>
Valavu yozungulira ya Eccentric ili ndi kusindikiza kwabwino, kutulutsa kwakukulu, kumatha kugwiritsidwa ntchito pakanthawi kosiyana.
Kuyambira kumayambiriro kwa zaka za m'ma 80, valavu yaing'ono yaing'ono yabwino inabadwa, yomwe imapangitsa kulemera ndi kutalika kwa valve yoyendetsera kutsika komanso mphamvu yothamanga bwino.
Kuyambira kumayambiriro kwa zaka za m'ma 1990, pogwiritsa ntchito makina oyendetsa makompyuta, zofunikira za mavavu owongolera anzeru zikuchulukirachulukira, ndipo zabadwa mitundu yosiyanasiyana yamagetsi yamagetsi yamagetsi ndi mavavu owongolera mabasi okhala ndi mavavu anzeru.
Kumayambiriro kwa zaka za zana la 2l, valavu yoyang'anira fieldbus yagwiritsidwa ntchito, ndikuyenda pansi kwa kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe kake
Kukula kwa valavu yoyang'anira ndi kuwongolera njira zama mafakitale kumachitika mogwirizana.
Pofuna kupititsa patsogolo kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe kake.
Mwachitsanzo, zinthu zodziwikiratu ndi zotumizira zimafunikira kuzindikira kwapamwamba ndi kufalikira, kuyankha mwachangu komanso kukhazikika kwa data; Oyang'anira ndi ma actuators ena amafunikira malo ang'onoang'ono akufa ndi kukangana, kubwereza kwabwinoko komanso nthawi yayitali yoyankha, ndipo atha kupereka chipukuta misozi chifukwa cha zomwe sizikuyenda mzere wa chinthucho.
Panthawi imodzimodziyo, chifukwa cha njira zazikulu komanso zabwino zopangira mafakitale, olamulira ndi zina zotero amaikanso patsogolo zofunikira.
Mfundo zazikuluzikulu za kukonza ma valve zimayambitsidwa mwachidule
Ndi njira zotani zoyikitsira zosinthira malo oyika ma valve, zomwe zitha kupititsa patsogolo magwiridwe antchito a valve ndikuchepetsa kuvala kwa ma valve? Zotsatirazi ndikuyambitsa mfundo zazikuluzikulu zosinthira kuyika ma valve kuti muwerenge. 1) Malo oyika, kutalika, malo olowera ndi njira yotulutsira ayenera kukwaniritsa zofunikira, ndipo kulumikizana kuyenera kukhala kolimba komanso kolimba. 2) Chigwiriro cha mitundu yonse ya mavavu apamanja omwe amaikidwa papaipi yotsekereza matenthedwe siyenera kutsika. 3) Valavu iyenera kuyang'aniridwa musanayike. Dzina la valve liyenera kugwirizana ndi dziko lamakono la "Universal Valve Mark" GB 12220. Kwa valavu yomwe mphamvu yake yogwira ntchito ndi yaikulu kuposa 1.0MPa ndipo imagwira ntchito yocheka pa chitoliro chachikulu, kuyesa mphamvu ndi zolimba ziyenera kuchitidwa. kunja musanayike, ndipo valavu yoyenerera ingagwiritsidwe ntchito. Kuyesa kwamphamvu, kuthamanga kwa mayeso ndi nthawi 1.5 kukakamiza mwadzina, nthawiyo si yochepera 5min, chipolopolo cha valve, kulongedza kuyenera kukhala koyenera popanda kutayikira. Kulimbitsa thupi, kuthamanga kwa mayeso ndi nthawi 1.1 za kukakamiza mwadzina; Kupanikizika kwa mayeso mu nthawi yoyeserera kuyenera kukwaniritsa zofunikira za GB 50243 muyezo, pamalo osindikizira a disc palibe kutayikira komwe kumayenera.
