Ukugaya kuyindlela esetshenziswa kakhulu yokuqedela esetshenziswayo yendawo yokubopha ye-valves kwinqubo yokukhiqiza. Ukugaya kungenza ingaphezulu le-valve leaving surface lithole ukunemba okuphezulu, ukwakheka kwejometri nobulukhuni, kepha alukwazi ukuthuthukisa ukunemba kwesikhundla phakathi kwendawo yokubekwa uphawu. Ukunemba okubucayi kwe-Ground Valve Seaning komhlaba kuvame ukuba ngu-0.001 ~ 0.003mm; ukunemba kwesimo sejometri (njengokungalingani) ngu-0,001mm; Ubulukhuni baphezulu ngu-0.1 ~ 0.008.
Isisekelo esiyisisekelo sokugaya okukaamboni komhlaba sifaka izici ezinhlanu: inqubo yokugaya, ukunyakaza kokugaya, isivinini sokugaya, ingcindezi yokugaya kanye nesibonelelo sokugaya kanye nemvume yokugaya kanye nemvume yokugaya.
1. Inqubo yokugaya
Ithuluzi lokugaya kanti ingaphezulu lendandatho yokubopha uphawu lihlanganiswe kahle, futhi ithuluzi lokugaya lenza ukunyakaza okugayiwe okuyinkimbinkimbi kanye endaweni ehlanganisiwe. Abrasives abekwe phakathi kwethuluzi lokushaya kanye nendandatho yendandatho yokubopha. Lapho ithuluzi lokushaya kanye nendawo yendandatho yokubopha uphawu lihamba ngokuhlobene, okuyingxenye yezingqwe ezingezona ezihlangene kuzo ukuslayida noma ukugoqa phakathi kwethuluzi lokushaya kanye nobuso bendandatho yokubopha. ungqimba lwensimbi. Iziqongo ngaphezulu kwendandatho yokubopha uphawu ziyindawo yokuqala, bese kutholakala i-geometry edingekayo kancane kancane.
Ukugaya akuyona kuphela inqubo yokwenza imishini yokuthambekela kwezinsimbi, kodwa futhi nesenzo samakhemikhali. Amafutha angenamsoco angakha ifilimu ye-oxide ebusweni ukuthi acutshungulwe, ngaleyondlela esheshayo inqubo yokugaya.
2 . ukunyakaza kokugaya
Lapho ithuluzi lokugaya futhi ingaphezulu lendandatho yokubopha uphawu lihamba ngokuhlobene, isamba sezindlela ezihambelana nezikhonkwane zephuzu ngalinye ngaphezulu kwendandatho yokubopha kufanele kufane. Futhi, indlela yokunyakaza okuhlobene kufanele iguquke njalo. Ukushintshwa okuqhubekayo kokuqondisa okuvinjelwe kuvimbela okusanhlamvu ngakunye kusuka ekuphindaphindeni i-trajectory yayo ebusweni bendandatho yokubopha, ukuze kungabingeli ukugqokwa kwendandatho yokubopha. Ngaphezu kwalokho, ukuguqulwa okuqhubekayo kokuqondisa kokunyakaza akunakukwenza ukuthi kusatshalaliswe ngokulinganayo, ukuze insimbi ebukhona endandatho yokubopha uphawu inganqunywa ngokulinganayo.
Yize ukunyakaza kokugaya kuyinkimbinkimbi futhi ukuqondiswa kokunyakaza kushintsha kakhulu, ukunyakaza kokugaya kuhlale kwenziwa phambi kwe-bonding force of the horting ring. Noma ngabe kungukugaya okwenziwa ngesandla noma ukunciphisa imishini, ukunemba kwesimo sejometri sokubekwa kwendandatho kwendandatho kuthinteka kakhulu ngokunemba kwesimo sejometri yethuluzi lokugaya nokunyakaza kokugaya.
3. isivinini sokugaya
Ngokushesha inhlangano yokugaya, esebenza kahle kakhulu ukugaya. Ijubane lokugaya liyashesha, izinhlayiya ezixakile ngokwengeziwe zidlula ebusweni bomsebenzi wesikhathi ngasinye isikhathi, futhi insimbi ethile iyanqunywa.
Ijubane lokugaya livame ukuba yi-10 ~ 240m / min. Kwemisebenzi yokusebenza edinga ukucaciswa okuphezulu kokugaya, ijubane lokugaya ngokuvamile alidluli ama-30m / min. Ijubane lokugaya lendawo yokubekwa uphawu le-valve lihlobene nokuqukethwe kwendawo yokubekwa uphawu. Ijubane lokugaya lendawo yokubekwa uphawu lethusi ne-cast iron yi-10 ~ 45m / min; indawo ebekelwe uphawu lensimbi elukhuni kanye ne-hard alloy ngu-25 ~ 80m / min; indawo ebekelwe uphawu lensimbi engenacala elingenacala 10 ~ 25m / min.
4. Ingcindezi Yokugaya
Ukusebenza kahle kokugaya kwandisiwe ngokwanda kwengcindezi yokugaya, futhi ingcindezi yokugaya akufanele ibe phezulu kakhulu, ngokuvamile 0.01-0.4MPA.
Lapho ugaya indawo yokubekwa uphawu ye-cast iron iron, ithusi nensimbi engenacala, ingcindezi yokugaya yi-0.1 ~ 0.3MPA; Indawo ebopha uphawu lensimbi elukhuni kanye ne-hard alloy ngu-0.15 ~ 0.4MPA. Thatha inani elikhudlwana lokugaya okunamandla nenani elincane lokugaya okuhle.
5. Isibonelelo Sokugaya
Njengoba ukugaya kuyinqubo yokuqeda, inani lokusika lincane kakhulu. Usayizi wesibonelelo sokugaya kuncike ekunembeni kwemishini kanye nokuqina kwenqubo yangaphambilini. Ngaphansi kwesisekelo sokuqinisekisa ukususwa kweminonjana yokucubungula kwenqubo yangaphambilini nokulungisa iphutha lejometri lendandatho yokubopha, incane isibonelelo sokugaya, okungcono.
Indawo yokubopha uphawu kufanele ibe yinhlabathi kahle ngaphambi kokugaya. Ngemuva kokugaya okuhle, ingaphezulu lokubekwa uphawu lingabhalelwa ngqo, futhi imvume ephansi yokugaya yile: Imvume yobubanzi ingu-0.08 ~ 0.020mm; Imvume yendiza ingu-0.006 ~ 0.015mm. Thatha inani elincane lapho ukugaya okwenziwa ngesandla noma ukuqina okubonakalayo kuphakeme, futhi kubhekwe inani elikhulu lapho ukugaya okugaya noma ukugedla okwenziwe ngezinto ezibonakalayo kuphansi.
Ingaphezulu lesivalo se-valve liphazamisa ukuba yindawo futhi licutshungulwe, ukuguquka okuhle kungasetjenziswa. Ngemuva kokuqeda ukujika, indawo yokubopha uphawu kufanele ibe yinhlabathi enzima ngaphambi kokuqeda, futhi imvume yendiza ingu-0.012 ~ 0.050mm.
I-Tianjin Tanggu Water-Seal-Seal-Seal I-Co, Ltd yaqanjwa ekwakhiweniUkukhulisa i-Butterfly valve Valve, I-SAGE VALVVVE, Y-strainer, ukulinganisa i-valve, I-valve yokuhlola, njll.
