Ukulimala kwe-seal ye-steam valve kuyimbangela eyinhloko yokuvuza kwangaphakathi kwe-valve. Kunezizathu eziningi zokwehluleka kwe-seal ye-valve, phakathi kwazo ukwehluleka kwe-seal pair eyakhiwe yi-valve core kanye nesihlalo kuyimbangela eyinhloko.
Kunezizathu eziningi zomonakalo wobuso bokuvala ama-valve, okuhlanganisa ukuguguleka komshini kanye nokuguguleka okusheshayo okubangelwa ukukhetha okungalungile, ukugoba kwemidiya, ukugqwala okuhlukahlukene, ukuminyana kokungcola, ukukhethwa kwe-valve core kanye nezinto zesihlalo kanye nenqubo yokwelapha ukushisa, ukuguqulwa kwe-sealing pair okubangelwa isando samanzi, njll. Ukuguguleka kwe-electrochemical, ukuxhumana kwezindawo zokuvala, ukuxhumana phakathi kobuso bokuvala nomzimba wokuvala nomzimba we-valve, kanye nomehluko wokuhlushwa kwe-medium, umehluko wokuhlushwa kwe-oxygen, njll., kuzodala umehluko ongaba khona, ukugqwala kwe-electrochemical kuzokwenzeka, futhi ubuso bokuvala ohlangothini lwe-anode buzoguguleka. Ukuguguleka kwamakhemikhali kwe-medium, i-medium eduze kobuso bokuvala kuzosebenza ngqo ngamakhemikhali nobuso bokuvala ngaphandle kokukhiqiza ugesi, kugqwale ubuso bokuvala.
Ukuguguleka kanye nokuguguleka kwe-medium, okuwumphumela wokuguguleka, ukuhlanzwa kanye nokuguguleka kwe-sealant surface lapho i-medium isebenza. Uma i-medium isesimweni esithile, izinhlayiya ezincane ezintantayo ku-medium zingqubuzana ne-sealant surface, okubangela umonakalo wendawo, kanti i-medium ehamba ngesivinini esikhulu ihlanza ngqo i-sealant surface, okubangela umonakalo wendawo. Ithinta i-sealant surface, okubangela umonakalo wendawo. Ukuguguleka kwe-medium kanye nesenzo sokushintshana sokuguguleka kwamakhemikhali kuzoguguleka kakhulu i-sealant surface. Umonakalo obangelwa ukukhetha okungafanele kanye nokuphathwa kabi. Kubonakala kakhulu ngokuthi i-valve ayikhethwanga ngokwezimo zokusebenza, futhi i-valve yokuvala isetshenziswa njenge-throttle valve, okuholela ekucindezelekeni okukhulu kokuvala kanye nokuvala okusheshayo noma ukuvala okubi, okubangela ukuthi i-sealant surface iguguleke futhi iguge.
Ikhwalithi yokucubungula yendawo yokuvala ayilungile, ikakhulukazi ibonakala ngamaphutha afana nokuqhekeka, ama-pores kanye ne-ballast endaweni yokuvala, okubangelwa ukukhethwa okungafanele kwemininingwane yokuvala nokushisa kanye nokuphathwa kabi ngesikhathi sokuvala nokushisa, kanti indawo yokuvala inzima kakhulu. Uma iphansi kakhulu, ibangelwa ukukhethwa kwezinto ezingalungile noma ukwelashwa okushisa okungafanele. Ubulukhuni bendawo yokuvala abulingani futhi abumelani nokugqwala. Ukufakwa okungalungile kanye nokugcinwa okungekuhle kuholela ekusebenzeni okungajwayelekile kwendawo yokuvala, futhi i-valve isebenza ngendlela enesifo, elimaza indawo yokuvala ngaphambi kwesikhathi. Ngezinye izikhathi ukusebenza okunonya kanye namandla okuvala ngokweqile nakho kuyimbangela yokwehluleka kwendawo yokuvala, kodwa ngokuvamile akulula ukuyithola nokuyahlulela.
Ukuminyana kokungcola kuyinkinga evamile, ngoba i-welding slag kanye nezinto ze-gasket eziningi ezingahlanzwa ekushiseni kwamapayipi omusi, kanye nokukalwa nokuwa kohlelo lomusi kuyizimbangela eziyinhloko zokungcola. Uma isihlungi somusi esine-mesh engu-100 singafakwanga phambi kwe-valve yokulawula, kulula kakhulu ukulimaza indawo yokuvala ebangelwa yi-jam. Kungabonakala ukuthi izizathu zomonakalo ebusweni bokuvala zingafingqwa njengomonakalo owenziwe ngumuntu kanye nomonakalo wokusetshenziswa. Umonakalo owenziwe ngumuntu ubangelwa yizici ezifana nomklamo ongemuhle, ukukhiqizwa okubi, ukukhethwa kwezinto okungafanele, ukufakwa okungafanele, ukusetshenziswa okubi kanye nokugcinwa okubi. Umonakalo wokusetshenziswa uwukuguguleka kwe-valve ngaphansi kwezimo zokusebenza ezijwayelekile, futhi kungumonakalo obangelwa ukuguguleka okungenakugwenywa kanye nokuguguleka kwendawo yokuvala yi-medium. Ukuvimbela umonakalo kunganciphisa ukulahlekelwa futhi kwandise impilo yesevisi. Kungakhathaliseki ukuthi hlobo luni lomonakalo, khetha i-valve yomusi efanele kahle, ufake, ulungiselele futhi ulungise amaphutha ngokuhambisana ngokuqinile nencwadi yokufaka. Ukugcinwa njalo kuwukwandisa impilo ye-valve nokunciphisa ukuvuza okubangelwa umonakalo ebusweni bokuvala.
