Ukucaciswa kwevalvu nezigaba kuzohambisana nezidingo zemibhalo yokuklama amapayipi
1, ibehlola i-valveimodeli kufanele ikhonjiswe ngokwezidingo zenombolo KAZWELONKE.Uma izinga lebhizinisi, kufanele libonise incazelo efanele yemodeli.
2, ibehlola i-valveingcindezi yokusebenza, izidingo ≥ ingcindezi yokusebenza kwepayipi, ngaphandle kokuthinta intengo yendawo, i-valve ingakwazi ukumelana nokucindezela kufanele kube kukhulu kunokucindezela kwangempela kwepayipi;Noma yiluphi uhlangothi lwe-valve kufanele lukwazi ukumelana ne-1.1 izikhathi zokucindezela kwe-valve ngaphandle kokuvuza;Isimo esivulekile se-valve, umzimba we-valve kufanele ukwazi ukumelana kabili nezidingo zokucindezela kwe-valve.
3, hlola i-valveamazinga okukhiqiza, kufanele achaze isisekelo senombolo Ejwayelekile KAZWELONKE, uma izinga lebhizinisi, inkontileka yokuthenga kufanele ifakwe kudokhumenti yebhizinisi.
Khetha impahla ye-valve yokuhlola
1. Impahla yevalvu, njengoba ipayipi lensimbi elimpunga linganconywa kancane kancane ukuthi lisetshenziswe, impahla yomzimba wevalvu kufanele ikakhulukazi ibe insimbi esakazwayo, futhi ibonise inombolo yomkhiqizo kanye nedatha yangempela yokuhlola ngokomzimba namakhemikhali yokulingisa.
2, i-stem material, lwela isiqu sensimbi engagqwali (20Cr13), i-valve enkulu yobubanzi kufanele futhi ibe isiqu esishumekiwe sensimbi engagqwali.
3, impahla yamantongomane, kusetshenziswa ithusi elicijile le-aluminium noma ithusi elicijile le-aluminium, futhi ubulukhuni namandla kukhulu kunesiqu
I-4, i-stem bushing material, ubulukhuni namandla ayo akufanele kube kukhulu kunesiqu, futhi esimweni sokucwiliswa kwamanzi nesiqu, umzimba we-valve awukhiqizi i-electrochemical corrosion.
5. Impahla yendawo yokuvala:
Izinhlobo zama-valve zihlukile, izindlela zokuvala kanye nezidingo zezinto ezibonakalayo zihlukile;
(2) I-valve yesango le-wedge evamile, impahla yensimbi yethusi, imodi yokulungisa, imodi yokugaya kufanele ichazwe;
(3) Idatha yokuhlolwa ngokomzimba, amakhemikhali nempilo yevalvu yesango elithambile kanye nempahla yomugqa wamapuleti;
(4) Ivalve yovemvane kufanele ikhombise into engaphezulu evalayo emzimbeni wevalvu kanye nezinto ezivalayo epuleti levemvane;Idatha yabo yokuhlola ngokomzimba namakhemikhali, ikakhulukazi izidingo zezempilo zenjoloba, ukusebenza okulwa nokuguga, ukumelana nokugqoka;Irabha kanye nerabha ye-epDM kuvame ukusetshenziswa, futhi irabha egaywe kabusha inqatshelwe ngokuphelele.
6, ukupakisha shaft valve
(1) Ngenxa yokuthi ama-valve kunethiwekhi yamapayipi avame ukuvulwa futhi avalwe ngokungavamile, ukupakisha kuyadingeka ukuthi kungasebenzi eminyakeni embalwa, ukupakisha akugugi, futhi umphumela wokuvala ugcinwa isikhathi eside;
(2) Ukupakishwa kwe-valve shaft kufanele futhi kube nokuvuleka nokuvala njalo, umphumela omuhle wokuvala;
(3) Ngenxa yalezi zidingo ezingenhla, isigcwalisi se-valve shaft asishintshi impilo yonke noma ngaphezulu kweminyaka eyishumi;
(4) Uma ukupakisha kudinga ukushintshwa, umklamo wevalvu kufanele ucabangele izinyathelo zokushintsha ngaphansi kwesimo sokucindezela kwamanzi.
Hlola ukusebenza kwe-valve test
1. Uma ukucaciswa okuthile kwevalvu kukhiqizwa ngamaqoqo, ukusebenza okulandelayo kuzohlolwa yiziphathimandla:
I-torque yokuvula nokuvala ye-valve ngaphansi kwengcindezi yokusebenza;
(2) ngaphansi kwengcindezi yokusebenza, ukuvuleka okuqhubekayo nokuvala izikhathi zevalvu kungaqinisekiswa;
(3) Ivalvu esesimweni sokudluliswa kwamanzi epayipini lokutholwa kwe-coefficient yamapayipi.
2. Ukuhlola okulandelayo kufanele kwenziwe ngaphambi kokuthi i-valve ihambe efektri:
(1) Lapho i-valve ivuliwe, umzimba we-valve kufanele uthwale kabili ukutholwa kwengcindezi yangaphakathi yevelu ye-valve yokusebenza kwengcindezi;
(2) Ngaphansi kwesimo esivaliwe, izinhlangothi zombili zevalvu ngokulandelana kwazo ngaphansi kwenani le-valve eyi-11, akukho ukuvuza;Kodwa metal seal uvemvane valve, ukuvuza value akuyona mkhulu kunezidingo ezifanele
I-anticorrosion yangaphakathi nangaphandle ye-valve yokuhlola
1, umzimba we-valve (kuhlanganise no-gearbox) ngaphakathi nangaphandle, kufanele kuqala udutshulwe uqhumisa ukugqwala kokuhlanza isihlabathi, ulwele ukufaka i-electrostatic spraying powder non-toxic epoxy resin, ukujiya kuze kufike ku-0?Ngaphezu kuka-3 mm.I-valve enkulu ye-electrostatic spraying non-toxic epoxy resin kunzima, kufanele futhi ibhulashwe, ifuthwe ngopende ofanayo ongenabuthi we-epoxy.
2. Zonke izingxenye zomzimba we-valve kanye nepuleti le-valve zidinga i-anticorrosion ephelele.Ngakolunye uhlangothi, ngeke igle uma icwiliswe emanzini, futhi ngeke kube khona ukugqwala kwe-electrochemical phakathi kwezinsimbi ezimbili.Izinto ezimbili ezibushelelezi zokunciphisa ukumelana namanzi.
3. Izidingo zezempilo ze-anticorrosive epoxy resin noma upende emzimbeni wevalvu kufanele zihlolwe iziphathimandla ezigunyaziwe ezihambisanayo.Izakhiwo zamakhemikhali nezomzimba kufanele nazo zihlangabezane nezidingo ezifanele.
Ukupakishwa kwe-valve nezokuthutha
1. Izinhlangothi zombili ze-valve kufanele zilungiswe ngepuleti lokuvimbela ukukhanya.
2. Amavalvu okulinganisa aphakathi nendawo namancane kufanele abotshwe ngentambo yotshani futhi ahanjiswe ngeziqukathi.
I-3, i-valve enkulu yobubanzi nayo inohlaka lwamapulangwe olulula lwamaphakheji angaguquki, ukuze ugweme ukulimala ngesikhathi sokuthutha
