Ukuvala i-valve kuhloswe ukuvimbela ukuvuza, futhi isimiso sokuvala i-valve sifundwa kusukela ekuvimbeleni ukuvuza. Kunezici eziningi ezithinta ukusebenza kokuvala i-valve.amavalvu ebhabhathane, okuhlanganisa ikakhulukazi okulandelayo:
1. Isakhiwo sokuvala
Ngaphansi kokushintsha kwezinga lokushisa noma amandla okuvala, isakhiwo sebhangqa lokuvala sizoshintsha. Ngaphezu kwalokho, lolu shintsho luzothinta futhi lushintshe amandla phakathi kwebhangqa lokuvala, ngaleyo ndlela kuncishiswe ukusebenza kokuvala ivalvu. Ngakho-ke, lapho ukhetha uphawu, qiniseka ukuthi ukhetha uphawu olunokuguquguquka okunwebekayo. Ngesikhathi esifanayo, naka futhi ubukhulu bomphezulu wokuvala. Isizathu ukuthi ubuso bokuxhumana bebhangqa lokuvala abukwazi ukufana ngokuphelele. Lapho ububanzi bomphezulu wokuxhumana womphezulu wokuvala bukhula, amandla adingekayo okuvala ayanda.
2. Ingcindezi ethile yobuso bokuvala
Ingcindezi ethile yendawo yokuvala ithinta ukusebenza kokuvala kweivalvu yebhabhathanekanye nokuphila kwe-valve. Ngakho-ke, ingcindezi ethile yendawo yokuvala nayo iyisici esibaluleke kakhulu. Ngaphansi kwezimo ezifanayo, ingcindezi ethile ephezulu kakhulu izobangela umonakalo we-valve, kodwa ingcindezi encane kakhulu izobangela ukuvuza kwe-valve. Ngakho-ke, sidinga ukucabangela ngokugcwele ukufaneleka kwengcindezi ethile lapho siklama.
3. Izakhiwo zomzimba zale medium
Izakhiwo zomzimba zale nto yokuxhumana nazo zithinta ukusebenza kokuvalaivalvu yebhabhathane. Lezi zakhiwo zomzimba zifaka phakathi izinga lokushisa, i-viscosity, kanye ne-hydrophilicity yomphezulu, phakathi kwezinye. Ukushintsha kwezinga lokushisa akuthinti nje kuphela ukuthamba kwe-sealing pair kanye nokushintsha kosayizi wezingxenye, kodwa futhi kunobudlelwano obungenakuhlukaniswa ne-viscosity yegesi. I-gas viscosity iyanda noma yehla ngokushisa okwandayo noma okwehlayo. Ngakho-ke, ukuze sinciphise ithonya lokushisa ekusebenzeni kokuvala kwe-valve, lapho siklama i-sealing pair, kufanele siyiklame njenge-valve ene-thermal recompensation njengesihlalo se-valve elastic. I-viscosity ihlobene nokuvuleka koketshezi. Uma ngaphansi kwezimo ezifanayo, i-viscosity inkulu, ikhono lokungena koketshezi liyancipha. I-hydrophilicity yomphezulu isho ukuthi uma kukhona ifilimu ebusweni bensimbi, ifilimu kufanele isuswe. Ngenxa yale filimu kawoyela encane kakhulu, izobhubhisa i-hydrophilicity yomphezulu, okuholela ekuvinjweni kweziteshi zoketshezi.
4. Ikhwalithi yokubopha uphawu
Ikhwalithi yokubopha isho ukuthi kumele sihlole ukunemba kokukhetha, ukufanisa kanye nokukhiqiza kwezinto. Isibonelo, idiski yevalvu ifanelana kahle nendawo yokubopha isihlalo sevalvu, okungathuthukisa ukusebenza kokubopha.
Ukuvuza kwamavalvu kuvame kakhulu empilweni nasekukhiqizweni, okungadala imfucuza noma kulethe ingozi empilweni, njengokuvuza kwamavalvu amanzi ompompi, kanye nemiphumela emibi, efana nobuthi, okulimazayo, okuvuthayo, okuqhumayo kanye nokuvuza kwezinto ezilimazayo, njll., kuyisongo esikhulu ekuphepheni komuntu siqu, ukuphepha kwempahla kanye nezingozi zokungcola kwemvelo. Khetha izivalo ezifanele ngokwezindawo ezahlukene kanye nezici zokusebenzisa.
