Pogwiritsa ntchito ndikupanga mapaipi amachitidwe amakala amakala, valavu yoyimilira imagwiritsidwa ntchito nthawi zambiri. Apa ndi kuwunika momwe amagwirira ntchito ndi magwiridwe ake. Lero, timvetsetsa limodzi.
Globe valve, yomwe imadziwikanso kuti valavu yodula, ndi amodzi mwamagetsi omwe amagwiritsidwa ntchito kwambiri. Ndiwotchuka chifukwa kusamvana pakati pa kusindikiza pamwamba pakutsegulira ndi kutseka ndikochepa, kulimba, kutalika kwake sikokulirapo, kosavuta kupanga, kukonza kosavuta, osati koyenera kutsika kwapakatikati, komanso koyenera kutsika kupanikizika. Gulugufe ya valve ndi valavu yosindikizidwa mokakamizidwa, chifukwa chake valavu ikatsekedwa, kuthamanga kuyenera kugwiritsidwa ntchito pa disc kukakamiza malo osindikiza kuti asatayike.
Mfundo yodula ya valve: valavu imadulidwa pamzere wake pakatikati komanso gawo lofunikira la kupindika, valavu yodulidwa, ngati mtundu wa ma valves ofunikira kwambiri, omwe amakhala ndi chikhomo pachitsulo cha valve, tsinde la valavu yolumikizana ndi axial kukanikizika kwa disc, mawonekedwe osindikiza a valavu ndi malo osindikizira a valve akukwanira bwino, kupewa kutayikira kwapakatikati pamipata pakati pa malo osindikiza.
Kusindikiza kwa valavu yapadziko lonse kumapangidwa ndi nkhope yosindikiza ya valve ndi nkhope yosindikiza ya valve. Tsinde limayendetsa chimbale cha valavu kuti chiziyenda molunjika pakati pa mpando wa valavu. Pakutsegula ndi kutseka valavu yapadziko lonse lapansi, kutalika kwake ndikochepa, ndikosavuta kusintha kayendedwe kake, ndipo ndikosavuta kupanga ndikusamalira, ndipo kukakamiza kumagwira ntchito zosiyanasiyana.
Poyerekeza ndi mafakitale opanga mtundu wina wa valavu yodula yomwe imagwiritsidwa ntchito kwambiri, kuchokera pamawonekedwe, valavu yapadziko lonse lapansi ndiyosavuta kuposa kale, yosavuta kupanga ndi kukonza. Mu moyo wautumiki, kudula kosindikiza kwa valavu sikophweka kuvala ndi zokopa, mukamatsegula ndikutseka chimbale cha valavu popanda kutsetsereka pakati pa _ kusindikiza pamwamba pampando, motero kuvala pang'ono ndikukanda pamtengo wosindikiza, kuti sinthani moyo wamautumiki a ma valavu osindikiza padziko lonse lapansi mukamayambira sitiroko yaying'ono, kutalika kwake ndi ma valve ena ang'onoang'ono. Chosavuta cha valavu yapadziko lonse ndikuti nthawi yotsegulira ndi kutseka ndi yayikulu ndipo ndizovuta kuzindikira kutsegula ndi kutseka mwachangu. Chifukwa njira yolumikizira thupi la valavu ndiyotopetsa komanso kutuluka kwamadzimadzi kumakhala kwakukulu, kutaya kwamadzi kwamadzimadzi kumakhala kwakukulu papaipi.
Kwa ma valve apadziko lonse, sikuti amangoyenera kukhazikitsa ndikusamalira, komanso kuti agwiritse ntchito.
1, tsegulani ndi kutseka valavu yapadziko lonse lapansi, mphamvuyo iyenera kukhazikika, osakhudzidwa. Kutsegula ndi kutseka kwa zida zamagetsi zamagetsi zamagetsi zapadziko lonse lapansi zaganiziranso zamphamvu izi ndipo valavu yapadziko lonse siyingafanane.
2. Valavu yapadziko lonse ikakhala yotseguka kwathunthu, chopukutira m'manja chiyenera kusinthidwa pang'ono, kuti ulusiwo ukhale wolimba, kuti tipewe kumasuka ndi kuwonongeka.
3. Mapaipi akagwiritsidwa ntchito koyamba, pamakhala zinyalala zambiri zamkati, motero valavu yodulidwa imatha kutsegulidwa pang'ono, kutsukidwa ndi kuthamanga kwa sing'anga, kenako ndikutseka pang'ono (osatsekedwa mwachangu kapena mwamphamvu, kuti zitsalira zotsalira zisapweteke malo osindikizira), adatsegulanso, kubwereza kangapo, kutsuka dothi loyera, kenako ndikuyamba kugwira ntchito yabwinobwino.
4. Nthawi zambiri mutsegule valavu yapadziko lonse lapansi, pamatha kukhala dothi pamalo osindikizira. Ikatsekedwa, njira yomwe ili pamwambayi iyeneranso kugwiritsidwa ntchito posambitsa, kenako ndikutseka mwalamulo.
5. Ngati chopukutira m'manja ndi chogwirira chawonongeka kapena kutayika, ayenera kukhala ndi zida nthawi yomweyo, ndipo sangasinthidwe ndi mbale yosunthira, kuti apewe kuwononga tsinde la valavu mbali zinayi, ndikulephera kutsegula ndi kutseka, kuti zimayambitsa ngozi pakupanga.
6, media, yozizira pambuyo poti valavu yodulidwa yatsekedwa, kuti chidule cha valavu, wothandizira akuyenera kutsekedwanso nthawi yoyenera, kuti malo osindikiza asasiye msoko wowonda, apo ayi, sing'anga kuchokera woonda msoko otaya yothamanga kwambiri, ndikosavuta kukokoloka kwa kusindikiza.
7. Ngati zapezeka kuti opaleshoniyi ndi yolemetsa kwambiri, zifukwa ziyenera kusanthulidwa. Ngati kulongedza kuli kothina, kumatha kumasuka bwino. Ngati tsinde la valavu lasokonekera, ogwira ntchitoyo ayenera kudziwitsidwa kuti akonze. Ma valve ena apadziko lonse lapansi, potsekedwa, magawo otsekera amakulitsidwe amadzimadzi, zomwe zimabweretsa mavuto otsegulira; Ngati iyenera kutsegulidwa panthawiyi, kumasula ulusi wa bonnet theka kutembenukira kutembenukira kumodzi kuti muchepetse kupsinjika kwa tsinde, kenako kokerani dzanja lamanja.
