Amavalvu ovemvane anosayizi omkhulu ngokuvamile abhekisela kumavalve ovemvane anobubanzi obukhulu kuno-DN500, ngokuvamile axhunywe ama-flange, ama-wafer.Kunezinhlobo ezimbili zamavalvu ovemvane anobubanzi obukhulu: i-valve uvemvane eligxilile kanye namavalve uvemvane.
Ungakhetha kanjani i-valve ye-butterfly enkulu?
1. Uma usayizi we-valve umncane kune-DN1000, ingcindezi yokusebenza ingaphansi kwe-PN16, futhi izinga lokushisa lokusebenza lingaphansi kuka-80℃, ngokuvamile sincoma i-valve butterfly yomugqa ogxilile njengoba izokonga kakhulu.
2. Ngokuvamile, lapho ububanzi bukhulu kuno-1000, sincoma ukusebenzisa i-valve butterfly eccentric, ukuze i-torque ye-valve incishiswe ngempumelelo ngenxa ye-eccentric angle ye-valve, evumela ukuvulwa nokuvalwa kwe-valve. i-valve.Ngaphezu kwalokho, i-valve butterfly eccentric inganciphisa noma iqede ukungqubuzana phakathi kwepuleti le-valve nesihlalo se-valve ngenxa ye-eccentric angle, futhi ithuthukise impilo yesevisi ye-valve.
3. Ngesikhathi esifanayo, ukwethulwa kwezihlalo zensimbi kuthuthukisa izinga lokushisa nokucindezela ukumelana kwama-valve emvemvane futhi kwandise ububanzi bokusebenzisa ama-valve.Ngakho-ke i-valve uvemvane enobubanzi obukhulu ephakathi nendawo ngokuvamile ingasetshenziswa kuphela ezimeni ezinengcindezi ephansi njengamanzi, kuyilapho i-valve uvemvane eccentric ingasetshenziswa ezindaweni ezinezimo zokusebenza eziyinkimbinkimbi kakhulu.

Isetshenziswa kuphi i-Big Size Butterfly valve
Ama-valve ovemvane anosayizi omkhulu asetshenziswa ezinhlobonhlobo zezinhlelo zokusebenza zezimboni lapho kudingeka khona isilinganiso esikhulu sokugeleza.Ezinye izinhlelo zokusebenza ezijwayelekile zamavalve evemvane ezinosayizi omkhulu zifaka:
1. Izikhungo zokuhlanza amanzi: Amavalvu ovemvane avame ukusetshenziswa ezindaweni zokuhlanza amanzi ukuze kulawulwe ukugeleza kwamanzi ngamapayipi amakhulu.
2. Izitshalo zikagesi: Amavalvu ovemvane asetshenziswa ezimbonini zikagesi ukuze kulawulwe ukugeleza kwamanzi noma isimusi ngamapayipi aphakela izinjini zomoya.
3. Izitshalo zokucubungula amakhemikhali: Amavalvu ovemvane asetshenziswa ezimbonini zokucubungula amakhemikhali ukulawula ukuhamba kwamakhemikhali ngamapayipi.
4. Imboni kawoyela negesi: Amavalvu ovemvane asetshenziswa embonini kawoyela negesi ukuze kulawulwe ukugeleza kukawoyela, igesi, nolunye uketshezi ngamapayipi.
5. Amasistimu e-HVAC: Amavalvu ovemvane asetshenziswa ezinhlelweni zokushisisa, zokungenisa umoya, nezomoya (HVAC) ukuze kulawulwe ukugeleza komoya emiseleni.
6. Imboni yokudla neziphuzo: Amavalvu ovemvane asetshenziswa embonini yokudla neziphuzo ukulawula ukuhamba koketshezi namagesi ngokusebenzisa imishini yokucubungula.
Sekukonke, amavalvu ovemvane anosayizi omkhulu asetshenziswa kunoma yisiphi isicelo lapho izinga lokugeleza elikhulu lidinga ukulawulwa futhi livalwe ngokushesha nangempumelelo.
Hlobo luni lwama-actuator oluvame ukusetshenziselwa ama-valve ovemvane anobubanzi obukhulu?
1.I-Worm Gear-Igiya lezikelemu lilungele amavalvu ovemvane osayizi abakhulu.Futhi iwukukhetha Kwezomnotho nokuphephile, Akudingi ukuncika endaweni yendawo, indawo eyanele yokusebenza.Ibhokisi legiya lezikelemu lingakhuphula itorque, kodwa lizonciphisa isivinini sokushintshwa.I-Worm gear butterfly valve iyakwazi ukuzivala futhi ngeke ihlehlise ukushayela.Mhlawumbe kukhona inkomba yesikhundla.
2.I-Electric Actuator-Ivalve yovemvane enobubanzi obukhulu kagesi idinga ukuhlinzeka amandla kagesi endlela eyodwa noma amandla kagesi ezigaba ezintathu esizeni, ngokuvamile i-voltage yendlela eyodwa engu-22V, i-voltage yezigaba ezintathu engu-380V, ngokuvamile amabhrendi aziwa kakhulu. I-Rotork.Isebenza ekusetshenzisweni kukagesi wamanzi, i-metallurgical, izicelo zasolwandle, ukudla kanye nezicelo zemithi, njll. idlala indima enkulu.
3.I-Hydraulic Actuator-I-valve enkulu ye-hydraulic butterfly ene-diameter inesiteshi se-hydraulic, izinzuzo zayo izindleko eziphansi, umsebenzi ozinzile nothembekile, ukusebenza okuphephile, kanye nekhono lokuvula nokuvala ngokushesha.
4.I-Pneumatic Actuator-Enkulu uvemvane womoyai-valve ikhetha i-valve ye-butterfly eqinile yensimbi enezinga eliphezulu ye-eccentric, ekwazi ukumelana nokushisa okuphezulu, evumelana nezimo, ukuyivula nokuvala kalula, futhi ivalwe ngokuphephile.I-actuator ye-butterfly valve actuator enobubanzi obukhulu, ngokwezimo zokusebenza zesayithi ukuze ukhethe..esetshenziswa kabanzi embonini ye-metallurgical ohlelweni lwepayipi yegesi yesithando somlilo ukugwema ukushisa kwegesi epayipini.
Ukusetshenziswa kosayizi omkhulu we-butterfly valve
I-valve ye-butterfly kagesi enobubanzi obukhulu isetshenziswa kabanzi ohlelweni lokushisa esiteshini samandla kanye nesistimu yokuqhekeka kwe-fan main duct kanye nensimbi, i-metallurgy, amakhemikhali nezinye izinhlelo zezimboni, kanye nokuvikelwa kwemvelo, ukuhlanzwa kwamanzi, ukuhlinzekwa kwamanzi ebhilidi eliphezulu kanye nepayipi lokudonsa amanzi. ukunqamula noma ukulawula indima yokugeleza.
Ngokusho kokukhethwa kwezinto ezibonakalayo kungasetshenziswa ezimweni ezingagqwali ze-carbon steel: -29 ℃ ~ 425 ℃ insimbi engagqwali: -40 ℃ ~ 650 ℃;imidiya esebenzayo yomoya, amanzi, indle, umusi, igesi, uwoyela, njll. Uhlobo lukagesi lwe-flange oluqinile lwe-butterfly valve luyingxenye ye-valve ye-butterfly yensimbi eqinile, isebenzisa isakhiwo se-eccentric esisezingeni eliphezulu se-multi-level ezintathu, sakhiwe i-actuator kagesi ye-DZW metal kanzima uphawu uvemvane valve.Izinga lokucindezela PN10-25=1.02.5MPa;Isilinganiso: DN50-DN2000mmimpahla: WCB cast steel carbon steel;304 insimbi engagqwali/316 insimbi engagqwali/304L insimbi engagqwali/316L insimbi engagqwali.
I-valve ye-butterfly kagesi enobubanzi obukhulu inesakhiwo esithembekile sokuvala imidiya yezindlela ezimbili, ukuvuza kwayo kunguziro;asikho isidingo sokususa i-valve epayipini ukuze ufake uphawu (ububanzi obukhulu kune-DN700);ama-bearings for self-lubricating bearings, awekho umjovo kawoyela, ukungqubuzana okuphansi;mpo, enezingqimba izinhlobo ezimbili zokufakwa, ngokuya ngezidingo zokuhlinzekwa;umzimba valve, butterfly ipuleti impahla ingasetshenziswa ingxubevange cast iron, ukusebenzisa abezindaba amanzi olwandle.
