Ubuchwepheshe obuphonsa i-butterfly valve

1. Ukuhlaziywa kwesakhiwo

(1) lokhuI-butterfly valveinesakhiwo esiyindilinga esenziwe ikhekhe, i-cavity yangaphakathi ixhunyiwe futhi isekelwa izimbambo ezi-8 zokuqinisa, i-top φ620 Hole ixhumana ne-cavity yangaphakathi, futhi konke okunyeisivalwanaivaliwe, kunzima ukulungiswa kwesihlabathi futhi kulula ukuzilimaza. Kokubili ukuqeda amandla nokuhlanza kwe-cavity yangaphakathi kuletha ubunzima obukhulu, njengoba kukhonjisiwe kuMfanekiso 1.

Ubukhulu bodonga lokukhonkotha buyehluka kakhulu, ubukhulu obuphezulu odongeni bufinyelela ku-380mm, futhi ubukhulu obuncane bodonga bungama-36mm kuphela. Lapho ukusakazwa kuqiniswe, umehluko wokushisa mkhulu, futhi i-shrinkage engalingani ingakhiqiza kalula ama-callage kanye nokuncipha kwezimpaphe, okuzodala amaphutha amanzi e-hydraulic test.

2. Inqubo Design:

. Uzinzile, ubude bekhanda le-cantilever eyinhloko yezimbobo ezimbili ezingaboni ngasohlangothini lude kunobude bomgodi, ukuze isikhungo somuntu odonsela phansi sibe nobuso bekhanda lesizinda ukuze baqinisekise ukuthi umnyombo wesihlabathi uhleliwe futhi uzinzile.

Uhlelo lokuthulula oluvaliwe luyamukelwa, ΣF Ngaphakathi: ΣF Okuvundlile: σF Straty = 1: 1.5: 1.3, i-SPRUE isebenzisa i-Cumber Tuber nge-Iron Curamic Feot, i-150 Phansi komgijimi, kanye namashubhu angama-12 we-ceramic abubanzi be-umgijimi wangaphakathi ukuze axhumane ngokulinganayo ezansi ithangi lokuqoqwa kwamanzi ezansi kwesihlungi esingezansi sokuthela phezulu, njengoba kukhonjisiwe kuMfanekiso 2

. Ubukhulu bebhokisi lesihlabathi bungama-3600 × 3600 × 1000 / 600mm, futhi bubhalwe nge-25mm elinamanzi amancane okuqinisekisa amandla anele nokuqina, njengoba kukhonjisiwe kuMfanekiso 3.

3. Ukulawulwa kwenqubo

.

Ukwenza okuyisisekelo Azikho okunye ukwesekwa kanye nezingxenye zokuphelelwa amandla ngaphandle kwekhanda eliphakathi nendawo. Uma isizinda se-carore singakwazi ukulungiswa futhi siqede, ukuhanjiswa kwesihlabathi kanye nezimbobo zomoya kuzovela ngemuva kokuthela. Ngoba indawo ephelele yesihlabathi isikhulu, ihlukaniswe izingxenye eziyisishiyagalombili. Kufanele kube namandla anele nokuqina ukuze uqinisekise ukuthi umnyombo wesihlabathi ngeke ulinyazwe ngemuva kokukhululwa kobumba, futhi ngeke alimaze ngemuva kokuthulula. Ukwehla kwezimo kwenzeka, ukuze kuqinisekiswe ubukhulu obunzulu odonga lokuphosa. Ngalesi sizathu, senza ngokukhethekile ithambo elikhethekile eliyisisekelo, futhi salibopha ethanjeni eliyisisekelo ngentambo yomoya omncane ukudweba igesi ephuma ekhanda eliyisisekelo ukuze liqinisekise ukuhlanganiswa kwesihlabathi lapho kwenza umnyombo. Njengoba kukhonjisiwe kuMfanekiso 4.

. Ngemuva kokumiswa, dweba ungqimba lwesibili ngopende we-magnesium osuselwa ngotshwala Ingxenye yekhanda eliyinhloko ilengiswa ngepayipi le-φ200 lesakhiwo esiyinhloko sethambo eliyisisekelo elinezikulufo ezintathu ze-M25, ezilungisiwe futhi zikhiywe ngebhokisi lesihlabathi eliphakeme elinezinsimbi bese lihlola ukuthi ingxenye yodonga ngayinye iyunifomu.

4. Ukuncibilika nokuthulula inqubo

. umkhondo izinto ezinjenge-p, s, ti, cr, PB, njll. Zilawulwa ngokuqinile kwinsimbi yesikebhe, futhi akukho ukugqwala kanye namafutha avunyelwe, isilinganiso sokungezwa singama-25% ~ 40%; Imali ekhokhwayo kufanele ihlanzwe ukuqhuma okudutshulwa ngaphambi kokuqinisekisa ukuqinisekisa ukuhlanzeka kwecala.

. ngangokunokwenzeka.

. Indlela evamile yokugcwala, i-0.15% ye-inoculation yesikhathi esisodwa isembozwe kwi-nodulizer ezansi kwephakethe, futhi ukugcwala kwe-spheroid kuqediwe. I-slag ikhishwe nge-inoculation yesibili ka-0.35%, futhi i-flow inoculation ka-0.15% yenziwa ngesikhathi sokuthulula.

. Insimbi ebilisiwe ayikwazi ukuphazanyiswa ngesikhathi sokuthulula, futhi inkomishi ye-sprue ihlala igcwele ukuvikela igesi kanye nokuthambisa ekubandakanyeni ekubunjweni ngomgijimi. umgodi.

5. Imiphumela yokuhlola yokuhlola

(1) Hlola amandla ashubile we-Cast Test Block: 485mpa, Elengation: 15%, iBrinell Hardness HB187.

. Isakhiwo se-metallographic sikhonjiswa kuMfanekiso 5.

.

.

(6) Ukuhlolwa kwengcindezi ye-20kg / cm2 / cm2 hydraulic Pressure ngemuva kokucubungula akukhombisanga ukuvuza

6. Isiphetho

Ngokwezici zesakhiwo sale valve yalevevelfly, inkinga yokungazinzi ngokweqile okuyisisekelo esikhulu sesihlabathi ekuhlanzeni isihlabathi okuphakathi nendawo okunzima kuxazululwa ngokugcizelela ukuklanywa kohlelo lwenqubo kanye nokusetshenziswa kwengubo ye-zirconium. Ukuhlelwa kwezimbobo ze-vent kugwema amathuba ama-pores ku-castings. Kusuka esithandweni sokulawula kanye nesikrini sokugijima, isikrini sokuhlunga se-foam ceramic kanye nobuchwepheshe be-minamic inganite kusetshenziselwa ukuqinisekisa ubumsulwa bensimbi ebilisiwe. Ngemuva kokwelashwa okuningi kwe-inoculation, isakhiwo se-metallographic of castrings kanye nokusebenza okuphelele kufinyelele kwizidingo ezijwayelekile zamakhasimende
