Ukonakala kwesitywina sevalve yomphunga ngoyena nobangela wokuvuza kwangaphakathi kwevalve.Kukho izizathu ezininzi zokungaphumeleli kwesitywina se-valve, phakathi kwayo ukungaphumeleli kwesibini sokutywinwa okuhlanganiswe nesiseko se-valve kunye nesihlalo sesona sizathu.
Kukho izizathu ezininzi zomonakalo wokutywinwa kwendawo yokutywinwa kwevalve, kubandakanywa ukunxiba komatshini kunye nokukhukuliseka kwesantya esiphezulu okubangelwa kukukhetha okungalunganga, i-cavitation yeendaba, i-corrosion eyahlukeneyo, i-jamming yokungcola, ukukhethwa kwesiseko se-valve kunye nezinto zokuhlala kunye nenkqubo yokunyanga ukushisa, iperi yokutywina ebangelwa yihamile yamanzi, njl njl. , njl., iya kuvelisa ukungafani okunokwenzeka, i-electrochemical corrosion iya kwenzeka, kwaye indawo yokutywina kwicala le-anode iya kuchithwa.Ukhukuliseko lwekhemikhali oluphakathi, okuphakathi kufutshane nomphezulu wokutywina kuya kusebenza ngokuthe ngqo kwikhemikhali kunye nomphezulu wokutywina ngaphandle kokuvelisa umsinga, ukhukulise umphezulu wokutywina.
Ukuguguleka kunye ne-cavitation ye-medium, okuyisiphumo sokugqoka, ukutshitshiswa kunye ne-cavitation yendawo yokutywina xa i-medium isebenza.Xa i-medium ikwisantya esithile, amasuntswana amahle adadayo phakathi angqubana nendawo yokutywina, ebangela umonakalo wendawo, kunye nesantya esiphezulu esishukumayo sihlamba ngqo umphezulu wokutywina, okwenza umonakalo wendawo.Ukuchaphazela umphezulu wokutywina, kubangela umonakalo wendawo.Ukhukuliseko oluphakathi kunye nesenzo esitshintshanayo sokhukuliseko lwekhemikhali luya kuwukhukulisa ngamandla umphezulu wokutywina.Umonakalo obangelwa kukukhetha okungafanelekanga kunye nokuphathwa kakubi.Ibonakaliswe ngokukodwa ukuba i-valve ayikhethwanga ngokwemiqathango yokusebenza, kwaye i-valve yokuvala i-valve isetyenziswe njenge-valve ye-throttle, ekhokelela ekunyanzeliseni ukuvala ngokugqithisileyo kunye nokuvalwa ngokukhawuleza okanye ukuvalwa kakubi, okubangela ukuba indawo yokutywina ibe yinto enzima. igugile kwaye igugile.
Umgangatho wokulungiswa komphezulu wokutywina awulungile, ubonakaliswa ikakhulu kwiziphene ezinje ngokuqhekeka, iipores kunye ne-ballast kumphezulu wokutywina, ezibangelwa kukukhetha okungafanelekanga komphezulu kunye neenkcukacha zonyango lobushushu kunye nokuphathwa kakubi ngexesha lokujonga kunye nonyango lobushushu, umphezulu wokutywina uqine kakhulu.Ukuba iphantsi kakhulu, ibangelwa kukukhethwa kwezinto ezingalunganga okanye unyango olungafanelekanga lokushisa.Ubunzima bomphezulu wokutywina abulingani kwaye abukwazi ukumelana nokuhlwa.ye.Ukufakela okungafanelekanga kunye nokugcinwa kakubi kukhokelela ekusebenzeni okungaqhelekanga kwendawo yokutywina, kwaye i-valve isebenza ngendlela enesifo, eyonakalisa ngokukhawuleza indawo yokutywinwa.Ngamanye amaxesha ukusebenza ngokukhohlakeleyo kunye nokuvala ngokugqithisileyo kukwazizathu zokungaphumeleli kwendawo yokutywina, kodwa kaninzi akulula ukuyifumana kunye nokugweba.
I-jam yokungcola yingxaki eqhelekileyo, kuba i-welding slag kunye ne-gasket engaphezulu kwezinto ezingahlanjululwanga kwi-welding yeepayipi ze-steam, kunye nokunyuka kunye nokuwa kwenkqubo ye-steam yizona zizathu zokungcola.Ukuba isihluzo se-100 se-mesh yomphunga asifakwanga phambi kwevalve yolawulo, kulula kakhulu ukonakalisa umphezulu wokutywina obangelwa yijam. Umonakalo owenziwe ngumntu kunye nomonakalo wesicelo.Umonakalo owenziwe ngumntu ubangelwa zizinto ezifana noyilo olulambathayo, ukwenziwa kakubi, ukukhetha izinto ngendlela engafanelekanga, ukufakwa ngokungafanelekanga, ukusetyenziswa kakubi kunye nokugcinwa kakubi.Umonakalo wesicelo kukuguga kunye nokukrazula kwevalve phantsi kweemeko eziqhelekileyo zokusebenza, kwaye ngumonakalo obangelwa ukhukuliseko olungenakuphepheka kunye nokukhukuliseka kwendawo yokutywina ngokuphakathi.Ukuthintela umonakalo kunokunciphisa ilahleko kunye nokwandisa ubomi benkonzo.Kungakhathaliseki ukuba luhlobo luni lomonakalo, khetha i-valve efanelekileyo yomphunga ngokuchanekileyo, faka, ulungiselele kwaye ulungise ngokuhambelana ngokungqongqo kunye nencwadana yokufakela.Ukugcinwa rhoqo kukwandisa ubomi bevalve kunye nokunciphisa ukuvuza okubangelwa ngumonakalo kwindawo yokutywina.
