Ukulimala kophawu lwe-valve yesitimu kuyimbangela eyinhloko yokuvuza kwangaphakathi kwe-valve.Kunezizathu eziningi zokungaphumeleli kwe-valve seal, phakathi kwazo ukwehluleka kwe-pair yokuvala okuhlanganiswe ne-valve core kanye nesihlalo kuyisizathu esiyinhloko.
Kunezizathu eziningi zokulimala kwe-valve sealing surface, okuhlanganisa ukuguga komshini kanye nokuguguleka kwesivinini esiphezulu okubangelwa ukukhetha okungalungile, i-cavitation yemidiya, ukugqwala okuhlukahlukene, ukugqwala kokungcola, ukukhethwa kwe-valve core kanye nesihlalo sempahla kanye nenqubo yokwelapha ukushisa, ukuguqulwa ipheya evalayo edalwe isando samanzi, njll. Ukuguguleka kwe-electrochemical, ukuthintana kwendawo evalayo, ukuxhumana phakathi kwendawo yokuvala nomzimba ovalayo kanye nomzimba we-valve, kanye nomehluko wokugxiliswa kwento emaphakathi, umehluko wokuhlangana komoyampilo , njll., izodala umehluko ongaba khona, ukugqwala kwe-electrochemical, futhi indawo yokuvala ohlangothini lwe-anode izoguguleka.Ukuguguleka kwamakhemikhali kwendawo ephakathi nendawo, okuphakathi nendawo eduze nendawo evalekayo kuzosebenza ngamakhemikhali ngokuqondile nendawo yokuvala ngaphandle kokukhiqiza amandla, kugugude indawo evalekayo.
Ukuguguleka kanye ne-cavitation ye-medium, okuwumphumela wokuguga, ukushaywa kanye ne-cavitation yendawo yokuvala lapho okuphakathi kusebenza.Uma i-medium isejubaneni elithile, izinhlayiya ezinhle ezintantayo phakathi nendawo zishayisana nendawo yokuvala, zidale umonakalo wendawo, kanti i-high-speed medium ezihambayo igeza ngokuqondile indawo yokuvala, ibangele umonakalo wendawo.Ithinta indawo yokuvala, ibangele umonakalo wendawo.Ukuguguleka kwe-medium kanye nesenzo esishintshayo sokuguguleka kwamakhemikhali kuzoguguleka kakhulu indawo evalekile.Umonakalo odalwe ukukhetha okungalungile nokungaphathwa kahle.Iboniswa ngokuyinhloko ukuthi i-valve ayikhethiwe ngokuvumelana nezimo zokusebenza, futhi i-valve yokuvala isetshenziswa njenge-valve ye-throttle, okuholela ekucindezelweni okuvala ngokweqile nokuvalwa okusheshayo noma ukuvala okungalungile, okubangela ukuthi indawo yokuvala ibe yi-valve. igugulekile futhi igugile.
Izinga lokucutshungulwa kwendawo yokuvala alilungile, ikakhulukazi libonakaliswa ngokukhubazeka okufana nokuqhekeka, ama-pores kanye ne-ballast endaweni evalwayo, okubangelwa ukukhethwa okungalungile kokucaciswa okungaphezulu kanye nokwelashwa kokushisa kanye nokusetshenziswa kabi ngesikhathi sokwelashwa kokungaphezulu nokushisa, indawo yokuvala iqine kakhulu.Uma iphansi kakhulu, ibangelwa ukukhetha okungalungile kwezinto noma ukwelashwa okungalungile kokushisa.Ubulukhuni bendawo yokuvala abulingani futhi abukwazi ukumelana nokugqwala.kwe.Ukufakwa okungalungile nokugcinwa okungalungile kuholela ekusebenzeni okuningi okungavamile kwendawo yokuvala, futhi i-valve isebenza ngendlela enesifo, elimaza ngaphambi kwesikhathi indawo yokuvala.Ngezinye izikhathi ukusebenza okunonya kanye namandla okuvala ngokweqile nakho kuyizizathu zokuhluleka kwendawo yokubeka uphawu, kodwa ngokuvamile akulula ukuthola nokwahlulela.
I-jam yokungcola iyinkinga evamile, ngoba i-slag ye-welding kanye ne-gasket material eyeqile engahlanzwa ekushiselweni kwamapayipi e-steam, futhi ukukala nokuwa kwesistimu ye-steam yizimbangela eziyinhloko zokungcola.Uma isihlungi se-steam esingu-100 mesh singafakiwe phambi kwevalvu yokulawula, kulula kakhulu ukulimaza indawo yokuvala ebangelwa ujamu. umonakalo owenziwe umuntu kanye nokulimala kwesicelo.Umonakalo owenziwe umuntu ubangelwa izici ezifana nokuklama okubi, ukukhiqizwa okungalungile, ukukhetha okungafanele kwempahla, ukufakwa ngendlela engafanele, ukusetshenziswa kabi kanye nokungakhathalelwa kahle.Ukulimala kwesicelo ukuguga nokudabuka kwevalvu ngaphansi kwezimo ezijwayelekile zokusebenza, futhi kuwumonakalo odalwe ukuguguleka okungenakugwemeka nokuguguleka kwendawo evalekayo yi-medium.Ukuvimbela ukulimala kunganciphisa ukulahlekelwa futhi kunwebe impilo yesevisi.Kungakhathaliseki ukuthi hlobo luni lomonakalo, khetha i-valve yesitimu efanele ngendlela efanele, faka, lungisa futhi ulungise ngokuhambisana ngokuqinile nebhukwana lokufaka.Ukugcinwa okuvamile kungukwelula isikhathi se-valve nokunciphisa ukuvuza okubangelwa ukulimala kwendawo yokuvala.
