I-valve uvemvane oluqinile olunama-bidirectionalinsimbi iye ensimbi ivaliwe.Kungaba futhi indandatho yophawu lwensimbi eya ensimbi evalwe uphawu noma yensimbi engagqwali eyindandatho yensimbi evalwe uphawu.Ngaphezu kwemodi yokushayela kagesi, i-valve ye-butterfly eqinile yezindlela ezimbili nayo ingashayelwa ngesandla, ngomoya, njll.
I-disc yeizindlela ezimbili metal seal uvemvane valveifakwe ohlangothini lobubanzi bepayipi.Kusiteshi esiyisilinda somzimba we-valve uvemvane, i-disc izungeza i-eksisi, futhi i-engeli yokuzungeza iphakathi kuka-0° no-90°.I-valve ivuleke ngokugcwele lapho i-disc izungeza ibe ngu-90°.
Ihlukaniswa ngokwesakhiwo: ihlukaniswe yaba i-valve uvemvane evala uphawu, ivalvevemvane evala uphawu olulodwa, i-valve uvemvane eccentric evala kabili futhii-valve ye-butterfly emithathu eccentric.
Ihlukaniswa ngokuvala izinto ezingaphezulu: ingahlukaniswa ngamavalve evemvane aqinile ahlanganisa izindlela ezimbili, okuyizinto ezithambile ezingezona ezensimbi noma izinto eziqinile zensimbi kuya ezintweni ezithambile ezingezona ezensimbi;futhi iphinde ihlukaniswe ngensimbi eqinile yokuvalwa kwama-butterfly valves, lapho ubuso obuvalayo buhlanganiswe ngezinto eziqinile zensimbi kuya ezintweni eziqinile zensimbi.
Isitoreji, Ukufakwa kanye nokusetshenziswa
1. Zombili iziphetho zevalvu zizovinjwa futhi zigcinwe ekamelweni elomile nelingena umoya.Kufanele ihlolwe njalo ukuze igcinwe isikhathi eside.
I-2.I-valve izohlanzwa ngaphambi kokufakwa ukuze kuqedwe ukukhubazeka okubangelwa ngesikhathi sokuthutha.
3. Ngesikhathi sokufakwa, amamaki kuvalvu kufanele ahlolwe.Futhi ukunakwa okukhethekile kuzokhokhwa ukuthi isiqondiso sokugeleza kwe-medium sihambisana nalokho okuphawulwe ku-valve.
4. Kumavalve ovemvane ane-actuator kagesi, kuzomele kuqashelwe ukuthi amandla kagesi axhunyiwe kufanele ahambisane nalawo akubhukwana ledivayisi kagesi.
Amaphutha Angenzeka, Izimbangela kanye Nezindlela Zokuqeda
1. Ukuvuza ku-filler
Uma amantongomane epuleti lokucindezela lokupakisha engaqiniswa noma aqiniswe ngokungalingani, amantongomane angaqiniswa kahle.Uma ukuvuza kuqhubeka, inani lokupakisha lingase linganele.Ngalesi sikhathi, ukupakisha kungalayishwa futhi bese uqinisa amantongomane.
2. Ukuvuza engxenyeni evalayo ye-valve yomzimba ne-disc plate
1) Hlanza ukungcola okuphakathi nendawo yokuvala.
2) Uma indawo yokuvala ilimele, phinda ugaye noma umshini bese ugaya umzimba we-valve futhi ngemva kokulungisa ukushisela.
3) Uma indawo ye-eccentric ingalungile, lungisa indawo ye-eccentric ibe indawo efanele ngesikhathi sokufaka.
