I-valve uvemvane lwe-taike lungahlukaniswa lube i-valve uvemvane womoya, i-valve uvemvane kagesi, i-valve uvemvane, njll. I-valve uvemvane uhlobo lwe-valve esebenzisa ipuleti uvemvane eliyindilinga njengengxenye yokuvula nokuvala futhi izungeza nesiqu se-valve ukuze ivuleke, vala, futhi ulawule umzila owuketshezi. Ipuleti uvemvane we valve uvemvane ifakwe ohlangothini ububanzi iphayiphi. Kusiteshi esiyisilinda somzimba wevalvu uvemvane, ipuleti uvemvane okumise okwediski lizungeza i-eksisi, nge-engeli yokuzungezisa phakathi kuka-0 ° no-90 °. Lapho ukujikeleza kufinyelela ku-90 °, i-valve ivuliwe ngokugcwele. I-Butterfly valve, eyaziwa nangokuthi i-flap valve, iyisakhiwo esilula esilawulayo futhi ingasetshenziselwa ukushintsha ukulawulwa kwemidiya yamapayipi anengcindezi ephansi. I-Butterfly valve (isiNgisi: i-butterfly valve) ibhekisela ohlotsheni lwe-valve lapho ingxenye yokuvala (idiski noma idiski) iyidiski ezungeza i-axis yevalvu ukuze kuvuleke nokuvala. Isebenza ikakhulukazi njenge-valve yokuvala kanye ne-throttling kumapayipi. Ingxenye yevalve uvemvane evula futhi evala ipuleti uvemvane olumise okwediski elizungeza i-eksisi yalo ngaphakathi komzimba wevalvu ukuze kufezwe injongo yokuvula, ukuvala noma ukulungisa. I-valve uvemvane ngokuvamile ingaphansi kuka-90 ° ukusuka ekuvulekeni ngokugcwele kuya ekuvalekeni ngokugcwele, futhi i-valve uvemvane nesiqu azinawo amandla okuzivalela. Ukuze ubeke ipuleti levemvane, isinciphisi segiya lezikelemu sidinga ukufakwa esiqwini sevalvu. Ukusetshenziswa kwesinciphisi segiya lezikelemu akugcini nje ngokwenza ipuleti levemvane libe nekhono lokuzikhiya futhi lime kunoma iyiphi indawo, kodwa futhi lithuthukisa ukusebenza kwe-valve. Izici zama-valve ovemvane ezimbonini ukumelana nezinga lokushisa eliphezulu, i-high pressure range, ubukhulu bobukhulu obujwayelekile, umzimba we-carbon steel, nendandatho yensimbi esikhundleni sendandatho yerabha yokuvala ipuleti le-valve. Amavalvu amakhulu ovemvane asezingeni eliphezulu akhiqizwa ngamapuleti ensimbi ashiselayo futhi asetshenziselwa ikakhulukazi amapayipi egesi aphakathi nendawo namapayipi egesi.
Ama-valve ovemvane angahlukaniswa abe uhlobo lwepuleti le-offset, uhlobo lwepuleti eliqondile, uhlobo lwepuleti ethambekele, kanye nohlobo lwe-lever ngokusho kwesakhiwo sazo. Ngokwefomu lokufaka uphawu, lingahlukaniswa ngezinhlobo ezimbili: okuvalwe ngokuqhathaniswa futhi kuvalwe kanzima. Uhlobo lokuvala oluthambile luvamise ukusebenzisa ukuvala indandatho yerabha, kanti uhlobo oluqinile lokuvala luvamise ukusebenzisa ukuvala indandatho yensimbi. Ngokusho kohlobo lokuxhuma, ingahlukaniswa ibe uxhumano lwe-flange nokuxhumeka kwe-wafer; Ngokwemodi yokudlulisela, ingahlukaniswa ngezinhlobo eziningana: i-manual, i-gear transmission, i-pneumatic, i-hydraulic, ne-electric.
1. Izinzuzo Butterfly Valves
1. Ukuvulwa nokuvala okulula nokusheshayo, ukonga abasebenzi, ukumelana noketshezi oluphansi, futhi kungasetshenziswa njalo.
2. Isakhiwo esilula, usayizi omncane, nesisindo esincane.
3. Ingakwazi ukuthutha udaka futhi igcine uketshezi oluncane emlonyeni wepayipi.
4. Ngaphansi kwengcindezi ephansi, ukubekwa uphawu okuhle kungafinyelelwa.
5. Ukusebenza okuhle kokushuna.
2. Ukubi kwe-Butterfly Valves
1. Ingcindezi yokusebenza kanye nebanga lokushisa lincane.
2. Ukusebenza kahle kokuvala uphawu.
3, Ukufakwa nokugcinwa kwama-valve ovemvane
1. Ngesikhathi sokufakwa, i-disc ye-valve kufanele imiswe endaweni evaliwe.
2. Isikhundla sokuvula kufanele sinqunywe ngokuvumelana ne-angle yokujikeleza yepuleti levemvane.
3. Ama-valve ovemvane anama-bypass valve kufanele avulwe ngaphambi kokuvula.
4. Ukufakwa kufanele kwenziwe ngokuvumelana nemiyalelo yokufaka yomkhiqizi, futhi ama-valve e-butterfly esindayo kufanele abe nesisekelo esiqinile.
5. Ipuleti uvemvane wevalve uvemvane ifakwe ohlangothini ububanzi iphayiphi. Kusiteshi esiyisilinda somzimba wevalvu uvemvane, ipuleti uvemvane okumise okwediski lizungeza i-eksisi, nge-engeli yokuzungezisa phakathi kuka-0 ° no-90 °. Lapho ukujikeleza kufinyelela ku-90 °, i-valve ivuliwe ngokugcwele.
6. Uma i-valve ye-butterfly iyadingeka ekulawuleni ukugeleza, into esemqoka ukukhetha usayizi olungile kanye nohlobo lwe-valve. Isimiso sesakhiwo samavalve ovemvane sifaneleka ngokukhethekile ekwenzeni ama-valve anobubanzi obukhulu. Ama-valve e-Butterfly awasetshenziswa kakhulu kuphela ku-petroleum, igesi, amakhemikhali, ukwelashwa kwamanzi nezinye izimboni ezijwayelekile, kodwa futhi asetshenziswa ohlelweni lwamanzi okupholisa esiteshini samandla ashisayo.
7. Kunamavalvu ovemvane amabili avame ukusetshenziswa: ivalve yovemvane yohlobo lwe-wafer kanye nevalve yohlobo lwe-butterfly. I-valve yovemvane yohlobo lwe-wafer iyivalvu exhunywe phakathi kwama-flange amapayipi amabili kusetshenziswa amabhawodi anamakhanda akabili. I-valve yohlobo lwe-butterfly iyi-valve ene-flange, futhi ama-flange emikhawulweni yomibili ye-valve axhunywe kwi-flange yepayipi kusetshenziswa amabhawudi.
8. Ipuleti uvemvane wevalve uvemvane ifakwe ohlangothini ububanzi iphayiphi. Kusiteshi esiyisilinda somzimba wevalvu uvemvane, ipuleti uvemvane okumise okwediski lizungeza i-eksisi, nge-engeli yokuzungezisa phakathi kuka-0 ° no-90 °. Lapho ukujikeleza kufinyelela ku-90 °, i-valve ivuliwe ngokugcwele.
