Ukusila yindlela esetjenziswa khulu yokuqeda ukuvala indawo yamavalvu ngesikhathi sokwenza. Ukugaya kungenza bona indawo yokuvala ivalvu ithole ukunemba okuphezulu, uburhaba bejamo lejometri noburhaba bendawo, kodwana angeze kwathuthukisa ukunemba kobujamo obufanako hlangana neendawo zokuvala. Ukunemba kwezinga lokuvala kwevalvu yephasi kuvamise ukuba ngu-0.001~0.003mm; ukunemba kwejamo lejometri (okufana nokungalingani) kungu-0.001mm; uburhaba bephasi buyi-0.1~0.008.
Umthetho oyisisekelo wokuvala ukugaya indawo ufaka hlangana izinto ezihlanu: ikambiso yokugaya, ukunyakaza kokugaya, ijubane lokugaya, umfutho wokugaya kanye nokuvunyelwa kokugaya.
1. Ikambiso yokugaya
Ithulusi lokugaya kanye nendawo yendandatho yokuvala zihlanganiswe kuhle, begodu ithulusi lokugaya lenza ukunyakaza okuyinkimbinkimbi kokugaya ebusweni bokuhlangana. Iinhlahla zibekwa hlangana nethulusi lokuvala kanye nendawo yokuvala. Lokha ithulusi lokuvala kanye nendawo yendandatho yokuvala ihamba ngokuya komunye nomunye, ingcenye yeenthoro ezihlabako ezise-abrasive izokutjhelela nofana igijima hlangana nethulusi lokuvala nendawo yendandatho yokuvala. isendlalelo sensimbi. Iinqongo ezisebusweni bendandatho yokuvala zithoma ngokugaya, bese kuthi i-geometry etlhogekako ifinyelelwe kancanikancani.
Ukusila akusiyo kwaphela ikambiso yemitjhini yezinto ezihlikihla iinsimbi, kodwana nesenzo samakhemikhali. Amafutha ase-abrasive angakha ifilimu ye-oxide ebusweni obuzokusetjenzwa, ngaleyo ndlela kurhabise ikambiso yokugaya.
2 . ukunyakaza kokugaya
Lokha ithulusi lokugaya kanye nendawo yendandatho yokuvala nayihamba ngokuya komunye nomunye, inani leendlela ezitjhelelako ezihlobeneko zephuzu ngalinye ebusweni bendandatho yokuvala ukuya ethuluzini lokugaya kufanele lifane. Godu, indlela yokunyakaza okuhlobeneko kufanele ihlale itjhuguluka. Ukutjhuguluka njalo kwendlela yokunyakaza kuvimbela ithoro ngalinye elihlabako bona lingabuyeli umzila walo ebusweni bendandatho yokuvala, ukwenzela bona kungabangeli amatshwayo wokuguga abonakalako begodu kwandise uburhaba bendawo yendandatho yokuvala. Ukungezelela, ukutjhuguluka okuragela phambili kwendlela yokunyakaza angeze kwenza bona i-abrasive isabalaliswe ngokulinganako, ukwenzela bona insimbi ebusweni bendandatho yokuvala ingasika ngokulinganako.
Nanyana ukunyakaza kokugaya kubudisi begodu indlela yokunyakaza itjhuguluka khulu, ukunyakaza kokugaya kuhlala kwenziwa eduze nendawo yokubopha yethulusi lokugaya kanye nendawo yendandatho yokuvala. Kungakhathaliseki bona kukusila ngezandla nofana kugaya ngomtjhini, ukunemba kwejamo lejometri lendawo yokuvala indandatho kuthinteka khulu ngokunemba kwejamo lejometri yethulusi lokugaya nokunyakaza kokugaya.
3. ibelo lokusila
Ukunyakaza kokugaya okurhabako, ukugaya kusebenza kuhle. Ijubane lokugaya lirhaba, iinhlayiya ezinengi ezihlabako zidlula ebusweni bendawo yokusebenza ngesikhathi seyunithi, begodu insimbi enengi iyaqunywa.
Ijubane lokugaya livamise ukuba yi-10~240m/min. Eensetjenzisweni ezitlhoga ukunemba okukhulu kokugaya, ijubane lokugaya ngokuvamileko alidluli i-30m/min. Ijubane lokusila lendawo yokuvala yevalvu lihlotjaniswa nento yendawo yokuvala. Ijubane lokugaya indawo yokuvala ithusi nensimbi ephosiweko yi-10 ~ 45m/min; indawo yokuvala yensimbi eqinileko ne-alloy eqinileko yi-25~80m/min; indawo yokuvala ye-austenitic stainless steel 10~25m/min.
4. ukugandeleleka kokusila
Ukusebenza kuhle kokugaya kukhuphuka ngokukhula komfutho wokugaya, begodu umfutho wokugaya akukafaneli ube phezulu khulu, ngokuvamileko 0.01-0.4MPa.
Lokha nawugaya indawo yokuvala yensimbi, ithusi kanye nensimbi engagqwali ye-austenitic, umfutho wokugaya ngu-0.1~0.3MPa; indawo yokuvala yensimbi eqinileko ne-alloy eqinileko ngu-0.15~0.4MPa. Thatha inani elikhulu lokugaya okurhabako kanye nenani elincani lokugaya okuncani.
5. Isibonelelo sokusila
Njengombana ukugaya kuyindlela yokuqeda, inani lokusika lincani khulu. Ubukhulu besibonelelo sokugaya buya ngokunemba kokusebenza ngomtjhini kanye noburhaba bendawo yendlela edlulileko. Ngaphasi kwesizathu sokuqinisekisa ukususwa kwemikhondo yokucubungula yendlela edlulileko nokulungisa iphutha lejometri lendandatho yokuvala, isibonelelo sokugaya sincani, kungcono.
Indawo yokuvala kufanele igayiwe kancani ngaphambi kokugaywa. Ngemva kokugaya okuhle, indawo yokuvala ingavalwa ngqo, begodu ubuncani bokugaya bu: ububanzi buyi-0.008 ~ 0.020mm; isabelo sendiza singu-0.006~0.015mm. Thatha inani elincani lokha ukugaya ngezandla nofana ubudisi bezinto buphezulu, begodu uthathe inani elikhulu lokha ukugaya ngomtjhini nofana ubudisi bezinto buphasi.
Indawo yokuvala yomzimba wevalvu ayilula ukusilwa nokusetjenzwa, ngalokho ukujika okuncani kungasetjenziswa. Ngemva kokuqeda ukujika, indawo yokuvala kufanele ibe phasi ngaphambi kokuqeda, begodu isabelo sendiza siyi-0.012~0.050mm.
I-Tianjin tanggu water-seal valve Co.,ltd beyikhethekileko ekukhiqizeniivalvu yevithamini ehleziko, ivalvu yesango, I-Y-strainer, ivalvu yokulinganisa, ivalvu yokuhlola i-wafer, njll.
