Ukuhlolwa kweValve
I. IkhwalithiImfuneko
Izidingo ezifanele zekhwalithi ye-valve sezibekiwephambiliezindinganisweni.
①Ingxenye yamakhemikhali kanyeimpahla yemishinizezinto eziyinhloko ze-valve zihambisana nezidingo emazingeni abalulekile wezinto ezibonakalayo.
②Iphutha lomumo nosayizi wevalvuukusakazaukuhlangabezana nemithethonqubo emidwebeni.
③IokungacutshunguliweIngaphezulu lama-valve castings lizoba sicaba, libushelelezi futhi lingangeniisihlabathi esinamathelayo, isikhumba se-oxide, imbobo,ukufakwa kwesihlabathi, imifantu noma okunye ukukhubazeka.The i-typecastingisibonakaliso siyakucaca, futhispruefuthiisikhuphukelikufanele igcinwe ilingana ne-castings surface ngemva kokuhlanza.
④Zonke izingxenye ze-valvengizouxhumeke ngokuqinile futhi ukhululeke ekuxegisweni.
⑤Timiphumela yokuhlolwa kwengcindezi futhiukubeka uphawuukuhlolwa kokusebenza kwe-valvevumelanato imfunekos wezindinganiso zokuhlola ezifanele.
⑥Iukusebenza kwe-valve kufanele kube ngaphansi kwengcindezi encane futhi kuqokweingcindezi ehlukile, futhi i-valve yokuqala neyokumisa izokhululeka kuyoukuphoqa.
⑦Ine-ezithileizikhathi zokusebenza nempilo yesevisi.
⑧It's evezwe kangconoumthamo wokugeleza(okusho ukuthiingcindeziukulahlekelwa ku-valve kuncane ngemva kokudlula kuyo).
II.Indlela Yokuhlola Nokuhlola
1,UkusakazaIkhwalithi
Iukusakazaubujamo nobukhulu buzokhambisana neimfunekoyemidwebo yobuchwepheshe nemithethonqubo evelaumfuni.Iubuncaneukuqina kodonga lwezingxenye ze-valve, iphutha lobude besakhiwo,ukususwa kwe-abrasionimvume yeipuleti lesangoakufanele kube ngaphansi kwezimfuneko zezinga lobuchwepheshe bomkhiqizo kanye nemidwebo yomkhiqizo.Ubuso obumangelengelei-valvefuthi igobolondo elicindezelwe lomkhiqizo we-valve ophelile ngeke libe nemifantu,ukuvala okubandayo, ukufakwa kwesihlabathi, izimbotshana nokunye ukukhubazeka.The isihlabathi esinamathelayo, sprue, isikhuphukelifuthiisikhumba se-oxidephezu kwe-castings surface kufanele ihlanzwe.
2,IngcindeziHlola
Ukuhlolwa kwengcindezi yikho kakhuluokuyisisekeloukuhlolwa kwe-valve.EI-valve ngayinye kufanele yenzelwe ukuhlolwa kwengcindezi ngaphambi kokulethwa efekthri.Tingcindezi yokuhlola kanye nobude besikhathi kulandela umthethonqubo kuI-GB/T13927, futhi izinto zokuhlola zihlanganisa ukuhlolwa kwegobolondo nokuhlolwa kokuvala uphawu.Uma kukhonaemuvaisakhiwo sokubeka uphawu ku-valve, kuyadingeka ukuqhubaukuhlolwa kwe-back seal. Dumchamo inqubo test, theamandla angaphandleokungase kuthinte umphumela wokuhlolwa akufanele kusetshenziswe kuvalvu.Ingcindezi yokuhlola izogcina ingashintshi phakathi nenqubo yokubamba ingcindezi nokuhlolwa.
Ukuhlolwa kwegobolondo levalvu kuwuhlobo lokuhlolwa kwengcindezi yegobolondo le-valve elixhunywe umzimba we-valve nekhava.Inhloso yayo ukuhlolaukubumbanaphakathi kwe-valve yomzimba kanye nesembozo, okungukuthi i-anti-ingcindeziumthamo wegobolondo eliphelele kufaka phakathi ukuxhumana komzimba we-valve nesembozo.
Iukuhlolwa kokuvala uphawu ukuhlola ukusebenza kweizingxenye ezivuliwekanye ne-valvei-sealing pair, futhi ingahlukaniswa ngokuhlolwa kokuvala uphawu koketshezi olunomfutho ophezulu kanye nokuhlolwa kokuvalwa komoya okunomfutho ophansi.
I-EC ingakunikeza ini?
Ezomnotho: Ngaphansi kwenani lezimboni, jabulela isevisi yokuhlola esheshayo nesezingeni eliphezulu
Isevisi eshesha kakhulu: Ngenxa yokuhlela ngokushesha, isiphetho sokuqala sokuhlolwa kwe-EC singatholwa esizeni ngemva kokuqedwa kokuhlolwa, futhi umbiko wokuhlola osemthethweni ovela kwa-EC ungatholwa lungakapheli usuku olu-1 lomsebenzi;ukuthunyelwa ngesikhathi kungaqinisekiswa.
Ukugada okusobala: Impendulo yesikhathi sangempela yabahloli;ukuphathwa okuqinile kokusebenza esizeni
Iqinile futhi ithembekile: Amaqembu ochwepheshe e-EC ezweni lonke ahlinzeka ngemisebenzi yobungcweti kuwe;Ithimba elizimele elizimele, elivulekile nelingenakonakala lihlelelwe ukuthi lihlole amaqembu okuhlola endaweni ngokungahleliwe futhi liqondise esizeni.
Isevisi eyenziwe ngokwezifiso: I-EC inekhono lesevisi elihamba kulo lonke uchungechunge lokuhlinzekwa kwemikhiqizo.Sizohlinzeka ngohlelo lwesevisi yokuhlola oluhambisana nesidingo sakho, ukuze sixazulule izinkinga zakho ngokuqondile, sinikeze inkundla yokuxhumana ezimele futhi siqoqe iziphakamiso zakho nempendulo yesevisi mayelana nethimba lokuhlola.Ngale ndlela, ungabamba iqhaza ekuphathweni kwethimba lokuhlola.Ngesikhathi esifanayo, ngokushintshisana kobuchwepheshe nokuxhumana, sizokunikeza ukuqeqeshwa kokuhlola, inkambo yokuphatha ikhwalithi kanye nesemina yobuchwepheshe ngesidingo sakho kanye nempendulo.
Ithimba Lekhwalithi ye-EC
Isakhiwo samazwe ngamazwe: i-QC ephakeme ihlanganisa izifundazwe zasekhaya namadolobha kanye namazwe ayi-12 aseNingizimu-mpumalanga ye-Asia
Amasevisi endawo: I-QC yendawo ingahlinzeka ngezinsizakalo zokuhlola ezichwepheshile ngokushesha ukuze wonge izindleko zakho zokuhamba.
Ithimba lochwepheshe: indlela eqinile yokungena kanye nokuqeqeshwa kwamakhono embonini kuthuthukisa ithimba lesevisi eliphakeme.
