Ukubeka uphawu ukuvimbela ukuvuza, futhi umgomo wokuvala ama-valve nawo uyacwaningwa ekuvimbeleni ukuvuza. Kunezici eziningi ezithinta ukusebenza kokuvalwa kweizivalo uvemvane, ikakhulukazi okuhlanganisa okulandelayo:
1. Isakhiwo sokubeka uphawu
Ngaphansi kokushintsha kwezinga lokushisa noma amandla okuvala, ukwakheka kwepheya yokuvala kuzoshintsha. Ngaphezu kwalokho, lolu shintsho luzothinta futhi luguqule amandla phakathi kwamapheya okuvalwa, ngaleyo ndlela kunciphise ukusebenza kokuvala ama-valve. Ngakho-ke, lapho ukhetha uphawu, qiniseka ukuthi ukhetha uphawu nge-deformation elastic. Ngesikhathi esifanayo, futhi unake ubukhulu bendawo yokubeka uphawu. Isizathu siwukuthi indawo yokuxhumana ye-pair yokufaka uphawu ayikwazi ukufaniswa ngokuphelele. Lapho ububanzi bendawo yokuxhumana yendawo yokuvala inyuka, amandla adingekayo ukuze kuvalwe ayanda.
2. Ukucindezela okuqondile kwendawo yokuvala uphawu
Ingcindezi ethile yendawo yokuvala ithinta ukusebenza kokuvala kweivalve uvemvanekanye nempilo yesevisi ye-valve. Ngakho-ke, ukucindezela okuqondile kwendawo yokubeka uphawu nakho kuyisici esibaluleke kakhulu. Ngaphansi kwezimo ezifanayo, ukucindezela okuphezulu kakhulu kuzodala ukulimala kwe-valve, kodwa ukucindezela okuncane kakhulu okuqondile kuzodala ukuvuza kwe-valve. Ngakho-ke, sidinga ukucabangela ngokugcwele ukufaneleka kwengcindezi ethile lapho siklama.
3. Izinto ezibonakalayo ze-medium
Izici ezibonakalayo ze-medium nazo zithinta ukusebenza kokutywinwa kweivalve uvemvane. Lezi zakhiwo zomzimba zihlanganisa izinga lokushisa, i-viscosity, kanye ne-hydrophilicity ebusweni, phakathi kokunye. Ukushintsha kwezinga lokushisa akuthinti nje kuphela ukuxega kombhangqwana ovala uphawu kanye nokushintsha kobukhulu bezingxenye, kodwa futhi kunobuhlobo obungenakuhlukaniswa ne-viscosity yegesi. I-viscosity yegesi iyanda noma yehla ngokunyuka noma ukuncipha kwezinga lokushisa. Ngakho-ke, ukuze kuncishiswe ithonya lokushisa ekusebenzeni kokuvala kwe-valve, lapho siklama ipheya yokuvala, kufanele siyiklame njengevalvu enesinxephezelo esishisayo njengesihlalo sevalvu enwebekayo. I-viscosity ihlobene nokungena koketshezi. Lapho ngaphansi kwezimo ezifanayo, i-viscosity enkulu, ikhono lokungena eliphansi loketshezi. I-hydrophilicity ebusweni isho ukuthi uma kunefilimu endaweni yensimbi, ifilimu kufanele isuswe. Ngenxa yale filimu kawoyela emincane kakhulu, izobhubhisa i-hydrophilicity ebusweni, okuholela ekuvinjweni kwemigudu yoketshezi.
4. Ikhwalithi yokuvala uphawu
Izinga lepheya yokuvala ngokuyinhloko lisho ukuthi kufanele sihlole ukukhethwa, ukufanisa kanye nokukhiqiza ukunemba kwempahla. Isibonelo, i-valve disc ihambisana kahle nendawo yokuvala isihlalo se-valve, engathuthukisa ukusebenza kokuvala.
Ukuvuza kwevalvu kuvame kakhulu empilweni nasekukhiqizeni, okungadala ukungcola noma kulethe ingozi empilweni, njengokuvuza kwamavalvu amanzi kampompi, nemiphumela engathi sína, njengobuthi, obuyingozi, obuvutha umlilo, ukuqhuma kanye Nokuvuza kwemithombo yezindaba egqwalayo, njll. , iwusongo olukhulu ekuphepheni komuntu siqu, ukuphepha kwempahla kanye nezingozi zokungcoliswa kwemvelo. Khetha izimpawu ezifanele ngokwezindawo ezahlukene kanye nezici zokusebenzisa.
