Namuhla, ifektri iJinbin iqedele ukupakishwa kwevalvu yesango elikhulu le-DN700. Lokhuivalvu yesango le-suliceihlolwe ngokucophelela futhi yalungiswa ngamaphutha ngabasebenzi, futhi manje isipakishiwe futhi isilungele ukuthunyelwa lapho iya khona.

Ama-valve esango amakhulu anobubanzi anenzuzo elandelayo:

1. Umthamo wokugeleza onamandla: Umklamo omkhulu uvumela inani elikhulu loketshezi ukuthi lidlule, kunciphisa ukumelana koketshezi futhi kuqinisekiswe ukuthuthwa koketshezi okubushelelezi.

2. Ukusebenza kahle kokuvala: Ukusebenzisa izinto zokuvala ezisezingeni eliphezulu kungavimbela ngempumelelo ukuvuza koketshezi futhi kuqinisekise ukusebenza okuphephile kohlelo.

3. Kulula ukuyisebenzisa: Ngokuvamile iqhutshwa yi-handwheel noma i-electric actuator, okulula ukuyisebenzisa futhi ingavula futhi ivale ngokushesha.

4. Ihlala isikhathi eside futhi ithembekile: Isakhiwo siqinile, siyakwazi ukumelana nokucindezela okukhulu kanye namandla okushaya, futhi sihlala isikhathi eside.

I-valve yesango lensimbi eliyi-ductile enobubanzi obukhulu ivame ukusetshenziswa ezimweni ezilandelayo:

1. Ubunjiniyela bokulondolozwa kwamanzi: Emadamini amakhulu, ezindaweni zokugcina amanzi nakwezinye izindawo zokulondolozwa kwamanzi, amavalvu esango amakhulu asetshenziswa ukulawula ukungena nokuphuma kwamanzi nokulawula amazinga amanzi.

2. Uhlelo lokuphakelwa kwamanzi kanye nokukhipha amanzi: Emapayipini okuphakelwa kwamanzi kanye nokukhipha amanzi edolobheni, ivalvu yesango lamanzi enobubanzi obukhulu ingasetshenziswa ukulawula indlela kanye nokugeleza kwamanzi, ukuqinisekisa ukusebenza okuvamile kokuphakelwa kwamanzi kanye nokukhipha amanzi.

3. Imboni yamakhemikhali kaphethiloli: Ezinhlelweni zamapayipi ezimbonini ezifana nephethiloli namakhemikhali, amavalvu esango anobubanzi obukhulu asetshenziswa ukulawula ukugeleza koketshezi namagesi ahlukahlukene, ukuvimbela ukuvuza nezingozi.

4. Imboni kagesi: Ezitshalweni zikagesi, eziteshini ezincane nakwezinye izikhungo zikagesi, amavalvu esango amakhulu asetshenziswa ukulawula ukugeleza koketshezi olufana namanzi apholile kanye nomusi, okuqinisekisa ukusebenza okuvamile kwemishini.

5. Ukwelashwa kwendle: Ezitshalweni zokwelashwa kwendle, i-valve yesango le-flange enobubanzi obukhulu isetshenziswa ukulawula ukugeleza kanye nokuqondisa kwendle, ukuqinisekisa inqubekela phambili ebushelelezi yenqubo yokwelashwa kwendle.

Ngakho-ke,ivalvu yesango enobubanzi obukhuluIntengo isetshenziswe kabanzi emikhakheni ehlukahlukene njengobunjiniyela bokulondolozwa kwamanzi, izinhlelo zokuphakelwa kwamanzi kanye nokukhipha amanzi, amakhemikhali kaphethroli, imboni yamandla, kanye nokwelashwa kwendle ngenxa yamandla awo okugeleza aqinile, ukusebenza kahle kokuvala, ukusebenza okulula, ukuqina, kanye nokuthembeka.
