Ndi mwayi kulandira mafunso kuchokera ku ntchito yothirira ku Morocco.Makasitomala ndi wotsogolera ntchito yothirira ku Morocco ndipo ndife okondwa kugwira naye ntchito.Makasitomala ali ndi zaka zopitilira 10 mumsika wothirira, ndipo amamvetsetsa mozama za kapangidwe ka polojekiti ndi valavu.Panthawi imodzimodziyo, makasitomala ali ndi zofunikira kwambiri za ma valve.Monga wopanga valavu ndi zaka zoposa 20 valavu kupanga zinachitikira, timatsatira mfundo kasitomala choyamba, pamodzi ndi mmene zinthu zilili mapolojekiti kasitomala ndi zosowa valavu, kupereka makasitomala ndi ntchito-wokonda madzimadzi mayankho.Pano, tikuthokozanso kwambiri kasitomala pogawana nafe momwe polojekitiyi ikuyendera, zomwe zimatithandiza kuti tipeze yankho labwino kwambiri.

Kuthirira ndi imodzi mwamafakitale omwe akuyembekeza kwambiri pakadali pano.Anthu amafunikira chakudya kuti apulumuke, ndipo pamene chiwerengero cha anthu chikukula, kufunika kwa chakudya kudzakweranso.Izi zinapangitsanso kuti ntchito yothirira ipite patsogolo.

Valavu ingagwiritsidwe ntchito poyendetsa kayendetsedwe ka kayendedwe ka payipi yaikulu ya madzi, kuthandizira kutuluka kwakukulu kwa famu, kutsekereza kapena kuyendetsa madzi, feteleza ndi mankhwala ophera tizilombo.Yambani ntchito yothirira, kuchepetsa ndalama za ogwira ntchito, ndikuwonjezera zokolola.
Pansipa, tikuwonetsa vavu ya COVNA yofunikira pa ulimi wothirira.

Valve ya Butterfly

Vavu ya butterfly ndi valavu yotembenukira kotala.Ubwino wake umaphatikizira kukula kwakukulu, kapangidwe kakang'ono, kupulumutsa malo oyika, ndipo kumatha kuwongolera bwino kuyenda kwamadzimadzi.Chifukwa cha kukula kwake kwakukulu, imatha kufika mainchesi 72.Choncho, ndizoyenera kwambiri kuyika mu mapaipi akuluakulu amadzi.

Pa nthawi yomweyi, tikukulimbikitsani kuti mugwiritse ntchitovalavu ya butterfly yamagetsi.Makina opangira magetsi ali ndi torque yayikulu, yomwe imatha kutsimikizira kuti valavu yagulugufe imatha kutsegulidwa kapena kutsekedwa kwathunthu.Panthawi imodzimodziyo, makina opangira magetsi amatha kulandira kapena zizindikiro zowonetsera, ndipo amatha kulamulira patali kutsegula kapena kutseka kwa valve kudzera mu dongosolo lolamulira kuti azindikire makina opanga mafakitale.

Kuphatikiza pa ma valve agulugufe amagetsi, titha kuperekansomavavu agulugufe amanjandimavavu a butterfly pneumatickuti musankhepo.

Valve ya Mpira

Mavavu onse a mpira ndi agulugufe ali m'gulu la quarter turn valve series.Chifukwa cha valavu yaing'ono ya mpira, nthawi zambiri amalangizidwa kuti ayike mu payipi ya madzi a nthambi kuti asinthe kayendedwe ka madzi.Valve ya mpira imathanso kusinthidwa kukhala valavu yanjira ziwiri kapena valavu yanjira zitatu kuti ikuthandizireni kusintha kayendedwe ka sing'anga.

Timalangizabe kuti musankhevalavu yamagetsi yamagetsikuti akupatseni njira yophatikizira yowongolera madzimadzi.Pa nthawi yomweyo, tikhoza kuperekavalavu ya mpira wamanjandivalavu ya mpira wa pneumaticchifukwa cha kusankha kwanu.

Pamwambapa, ndikuyambitsa mwachidule mavavu a COVNA omwe angagwiritsidwe ntchito kuthirira.Ngati muli ndi zosowa za mavavu a COVNA, chonde tiuzeni kuti mupeze mayankho oyenera a valve ndi mitengo yabwino!
