I-GDF-1 Motorized Ball Valve Special for Gas Pipeline
Indawo yokufaka
I-valve yebhola elintantayo ingafakwa epayipini legesi
Izinzuzo Zomkhiqizo
Isici kanye nezinzuzo zevalvu yepayipi yegesi
1. Ingcindezi yokusebenza inkulu, futhi i-valve ingavulwa futhi ivalwe ngokuzinzile endaweni yokusebenza engu-0.4MPa.
2. Isikhathi sokuvula nokuvala i-valve sifushane, futhi isikhathi sokuvula nokuvala i-valve singaphansi noma silingana nama-50s ngaphansi komkhawulo wokusebenza kwamandla ka-7.2V.
3. Akukho ukulahlekelwa kwengcindezi, futhi idizayini yesakhiwo sokulahlekelwa kwe-zero-pressure ene-diameter ye-valve elingana nobubanzi bepayipi iyamukelwa.
4. Ukusebenza kokuvala kwe-valve yokuvala kuhle, futhi uphawu lwenziwe ngerabha ye-nitrile enokumelana nokushisa okuphezulu (60℃) kanye nezinga lokushisa eliphansi (-25℃).
5. Ngokushintsha komkhawulo, ingakwazi ukubona ngokunembile isimo esikuso se-valve yokushintsha.
6. I-valve yokuvala isebenza kahle, ngaphandle kokudlidliza nomsindo ophansi.
7. Ibhokisi lenjini negiya livalwe ngokugcwele, futhi izinga lokuvikela lithi ≥IP65, elivimbela ngokuphelele i-transmission medium ukuthi ingangeni, futhi inokusebenza okuhle kokuvikela ukuqhuma.
8. Umzimba we-valve wenziwe nge-aluminium, engakwazi ukumelana nokucindezela kwe-1.6MPa, ukumelana nokushaqeka nokudlidliza, futhi ivumelane nezimo eziyinkimbinkimbi.
9. Ingaphezulu lomzimba we-valve li-anodized, elihle futhi elihlanzekile futhi linokusebenza okuhle kokulwa nokubola.
Umyalelo Wokusetshenziswa
1. Intambo ebomvu kanye nentambo emnyama yizintambo zamandla, intambo emnyama ixhunywe ku-electrode ephozithivu, futhi intambo ebomvu ixhunywe ku-electrode eyinegethivu ukuze uvule ivalvu.
2. Imigqa yokuphuma kwesignali endaweni yokuzikhethela: Imigqa emhlophe emi-2 imigqa yesignali evulekile ye-valve endaweni, efinyezwayo lapho i-valve isendaweni; Imigqa emi-2 eluhlaza okwesibhakabhaka imigqa yesignali ye-valve-vala endaweni, ene-circuited emfushane lapho i-valve isendaweni; (Ngemva kokuthi i-valve ivuliwe noma ivaliwe, ukunikezwa kwamandla kuvame ukunwetshwa ama-5s ukuze kuqinisekiswe ukuzinza kwesignali esendaweni)
3. Ibhokisi le-deceleration le-valve lingashintshwa ngama-degree angu-180 lilonke ngokuvumelana nokunethezeka kwekhasimende ukufaka ibhokisi lokulawula, futhi i-valve ingasetshenziswa ngokujwayelekile ngemva kokujikeleza.
4. Sebenzisa amabhawodi e-flange ajwayelekile ukuxhuma ama-valve, amapayipi, nama-flowmeters. Ngaphambi kokufakwa, ubuso bokugcina be-flange kufanele buhlanzwe ngokucophelela ukuze kuvinjwe i-iron slag, ukugqwala, uthuli nezinye izinto ezibukhali endaweni yokuphela ekukhipheni i-gasket futhi kubangele ukuvuza.
5. I-valve kufanele ifakwe epayipini noma i-flowmeter i-valve ivaliwe. Akuvunyelwe ngokuphelele ukuyisebenzisa esimweni sokucindezelwa ngokweqile noma ukuvuza kwegesi kanye nokubona ukuvuza ngomlilo ovulekile.
6. Ukubukeka kwalo mkhiqizo kunikezwe ne-nameplate.
