1. Njira yoyeretsera
Slag yowotcherera, dzimbiri ndi slag mu payipi imayambitsa kutsekeka kapena kupindika m'mphepete, gawo lowongolera ndi dzenje lachivundikiro chakumunsi cha valve, zomwe zimapangitsa kukoka ndi kukanda pamwamba pa pachimake cha valve ndi malo owongolera, ndikulowa pamalo osindikizira. Izi nthawi zambiri zimachitika kumayambiriro kwa ntchito yatsopano komanso pambuyo pokonzanso. Ichi ndiye cholakwa chofala kwambiri. Pankhaniyi, ndikofunikira kuchotsa slag kuti muyeretsedwe, ndikupera ngati malo osindikizira awonongeka; nthawi yomweyo, tsegulani pulagi yapansi kuti muthamangitse slag yomwe ikugwera mu chivundikiro cha valve yapansi kuchokera pabowo, ndikutsuka payipi. Asanayambe kugwira ntchito, valavu yowongolera iyenera kutsegulidwa kwathunthu ndipo sing'angayo idzayenda kwa nthawi yayitali isanayambe kugwira ntchito bwino.
2. Njira yokwapula kunja
Pamene valavu wamba amagwiritsidwa ntchito kuwongolera sing'anga yomwe imakhala yosavuta kugwa ndipo imakhala ndi tinthu tating'onoting'ono, nthawi zambiri imatsekedwa pamphepete mwa nyanja ndi chiwongolero. Mpweya wothamanga ndi nthunzi ukhoza kulumikizidwa pansi pa pulagi ya chivundikiro chapansi cha valve. Vavu ikatsekedwa kapena kukakamira, tsegulani mpweya wakunja kapena valavu ya nthunzi kuti mutsirize ntchito yothamanga popanda kusuntha valve yolamulira, kuti valavu igwire ntchito bwino.
3. Kuyika kwa sefa yamapaipi
Kwa valavu yaing'ono ya caliber control valve, makamaka valavu yaying'ono yoyendetsera kayendedwe kake, kutulutsa kwake kumakhala kochepa kwambiri, ndipo sikuyenera kukhala ndi slag pakati. Pakakhala kutsekeka, ndi bwino kuyika zosefera papaipi kutsogolo kwa valavu kuti zitsimikizire njira yosalala ya sing'anga. Kwa valavu yowongolera yokhala ndi malo, choyikapo sichigwira ntchito bwino, ndipo cholakwika chofala kwambiri ndi kutsekeka kwa doko lake. Choncho, pogwira ntchito ndi choyikapo, mpweya uyenera kuyendetsedwa bwino. Njira yokhazikika ndikuyika valavu yochepetsera fyuluta ya mpweya paipi ya mpweya kutsogolo kwa choyikapo
4. Wonjezerani chilolezo cha throttle
Mwachitsanzo, particles olimba sing'anga kapena kuwotcherera slag ndi dzimbiri otsukidwa mu payipi sangathe kudutsa throttling orifice ndi chifukwa blockage, kupanikizana ndi zolakwa zina. Zigawo zopukutira zokhala ndi chilolezo chachikulu chopumira, monga pakati pa valve ndi manja okhala ndi zenera komanso malo otseguka, atha kugwiritsidwa ntchito m'malo mwake. Chifukwa chakuti malo otsekemera amakhala okhazikika m'malo mogawidwa mozungulira, cholakwikacho chikhoza kuthetsedwa mosavuta. Ngati ndi valavu yapampando umodzi kapena valavu yokhala ndi mipando iwiri, valavu yooneka ngati plunger imatha kusinthidwa kukhala valavu yooneka ngati V kapena valavu ya manja. Mwachitsanzo, valavu yokhala ndi mipando iwiri mu chomera chamankhwala nthawi zambiri imamangiriridwa, choncho tikulimbikitsidwa kugwiritsa ntchito valavu ya manja, ndipo vutoli limathetsedwa mwamsanga.
5. Njira yapakatikati yokwapula
Pogwiritsa ntchito mphamvu yowotcha ya sing'anga yokhayo, imatha kukwapula ndikuchotsa zinthu zomwe zimakhala zosavuta kutsitsa ndikutsekereza, kuti zithandizire kuletsa kutsekereza kwa valve. Njira zodziwika bwino ndi izi: ① kusintha kwa mtundu wotsekedwa; ② gwiritsani ntchito ma valve owongolera; ③ ikani khosi la throttle orifice pamalo owopsa kwambiri, ndipo tcherani khutu kuti muwongolere kukokoloka kwa zinthu zomwe zimagwira.
6. Njira yowongoka imasinthidwa kukhala njira ya angular
Njira yowongoka ndi inverted s flow, njira yolowera ndi yovuta, ndipo pali madera ambiri akufa kumtunda ndi m'munsi, zomwe zimapereka malo amvula yapakati. Kulumikizana kwa angular, sing'anga ngati ikuyenda mu 90 ℃ chigongono, ntchito yabwino yopukutira, malo ang'onoang'ono akufa, osavuta kupanga kukhala mzere wotuluka. Choncho, pamene valavu yowongoka yowongoka imatsekedwa pang'ono, imatha kusinthidwa kukhala valavu ya ngodya.
