Ucwaningo Ngethonya Lokunyakaza Kwevaluvu Yenaliti Yomjovo Wenjini Kadizili Ezicini Zomjovo Zembobo Ngayinye (ingxenye1)

Njengoba imithetho yokukhipha igesi nemithetho yokusetshenziswa kukaphethiloli iya ngokuya iqina, izinjini ezivuthayo zangaphakathi ziyaqhubeka nokuya eziqondisweni ezihlanzekile, eziphumelelayo, nezonga amandla.Imithetho eqinile yokukhipha uphethiloli ibeka phambili izidingo eziphakeme zohlelo lokunikezwa kukaphethiloli, futhi umfutho womjovo kaphethiloli ungafinyelela cishe ku-250MPa noma ngisho nangaphezulu.Isitimela esivamile esinengcindezi ephezulu sesiphenduke insakavukela emkhakheni wezinjini zikadizili ngenxa yezinzuzo zayo eziyingqayizivele, kanti isijojo sikaphethiloli, njengoba i-terminal actuator exhuma isistimu yesitimela esinengcindezi ephezulu kanye nomjovo kaphethiloli ongezansi, iyazicacela.Umbhangqwana we-valve yenaliti awugcini nje ngokuthwala indima yokugcotshwa kukaphethiloli, ukuvala uphawu nokujikeleza, kodwa futhi usebenza njengengxenye yokwenziwa okuqondile komjovo kaphethiloli, onquma izici zokujova uphethiloli nesifutho, bese uthinta ikhwalithi elandelayo yokuxuba uphethiloli negesi izici zokukhishwa.

Umhlangano we-valve yenaliti wakhiwe nge-valve yenaliti kanye nomzimba we-valve yenaliti.Ngokukhula okuqhubekayo komfutho ojwayelekile womjovo wesitimela ovamile, ukugeleza kukaphethiloli wengcindezi ephezulu ku-nozzle (okuhlanganiswe ukuhlanganiswa kwevalvu yenaliti, igumbi lokucindezela, njll.) akugcini nje ngokuba nenombolo ye-Reynolds ephezulu. ihambisana ne-cavitation ebangelwa ukufinyela kwe-pulse kanye nokunyakaza kwe-vortex ye-fluid, okwenza ukugeleza okuyinkimbinkimbi kwegesi-uketshezi lwezigaba ezimbili, okuphinde kuthinte ikhwalithi ye-atomization kaphethiloli ekuphumeni kwembobo ye-nozzle.Ngokusekelwe kulokhu, ngokombono wokunyakaza kwesikhashana kwe-valve yenaliti, leli phepha lihlaziya ithonya lokunyakaza okuvamile (ngaphandle kokucabangela i-eccentricity) nokunyakaza okungavamile (kucatshangelwa i-eccentricity) ye-valve yenaliti ekugelezeni kwangaphakathi nezici zomjovo zomunye nomunye. hole, futhi ithuthukisa indlela ebheka ukucindezelwa kwamafutha kaphethiloli.Ngokusekelwe kumodeli ye-gas-liquid yezigaba ezimbili zokugeleza kwe-transonic ku-nozzle, izici ezinethonya zokuwohloka kokunwebeka kanye nokunyakaza kwe-eccentric ye-valve yenaliti kuyahlolwa, okunikeza isisekelo sethiyori sokuthuthukisa ukwakheka nokukhiqizwa komjovo.
