1. Izici zesakhiwo
Kunomehluko osobala phakathi kwevalve yovemvane yesigaba A kanye nesigaba B sovemvane ivelufa ngesakhiwo.
1.1 Isigaba A Amavalvu ovemvane awuhlobo "olugxile", ngokuvamile anesakhiwo esilula, esihlanganisa umzimba wevalvu, idiski yevalvu, isihlalo sevalvu, i-valve shaft kanye nedivaysi yokudlulisela. I-valve disc ine-disc futhi izungeza i-valve shaft ukulawula ukugeleza koketshezi.
1.2 Ngokuphambene, ama-valve e-butterfly esigaba B awuhlobo lwe-"offset", okusho ukuthi i-shaft isusiwe kudiski, iyinkimbinkimbi kakhulu futhi ingase ibe nezimpawu ezengeziwe, izisekelo, noma ezinye izingxenye zokusebenza ukuze zinikeze ukusebenza kokuvala okukhulu nokuzinza.
2. Aizinhlelo zokusebenza ezimweni ezahlukene zokusebenza
Ngenxa yomehluko wesakhiwo, i-valve ye-butterfly yesigaba A kanye ne-valve ye-butterfly yesigaba B nazo zisetshenziswa ezimeni zokusebenza ezahlukene.
2.1 Isigaba A amavalvu ovemvane asetshenziswa kakhulu ekucindezelweni okuphansi, ohlelweni lwamaphayiphi obubanzi obukhulu, njengamapayipi amanzi, ukungena komoya nezinye izimboni, ngenxa yesakhiwo sawo esilula, usayizi omncane, isisindo esilula nezinye izici.
2.2 I-valve ye-butterfly yeSigaba B ifaneleka kakhulu ekusetshenzisweni kokusebenza okunezidingo zokusebenza zokuvala okuphezulu nokucindezela okukhulu okuphakathi nendawo, okufana namakhemikhali, uphethiloli, igesi yemvelo nezinye izimboni.
3. Ukuqhathaniswa kwenzuzo yokusebenza
3.1 Ukusebenza kokuvala: amavalvu ovemvane esigaba B ngokuvamile angcono kunesigaba A sovemvane ekusebenzeni kokuvala, ngenxa yesakhiwo sawo esiyinkimbinkimbi kanye nomklamo owengeziwe wophawu. Lokhu kwenza i-valve ye-butterfly yesigaba B ukuthi igcine umphumela omuhle wokuvala endaweni enzima njengomfutho ophezulu kanye nezinga lokushisa eliphezulu.
3.2 Umthamo wokugeleza: Umthamo wokugeleza wesigaba I-valve uvemvane unamandla, ngoba idizayini yediski ye-valve ilula, ukumelana noketshezi oludlulayo kuncane. I-valve ye-butterfly yesigaba B ingase ithinte ukusebenza kahle kokugeleza koketshezi ngezinga elithile ngenxa yesakhiwo sayo esiyinkimbinkimbi.
3.3 Ukuqina: Ukuqina kwamavalvu ovemvane esigaba B kuvame ukuba phezulu, ngenxa yokuthi ukwakheka kwesakhiwo nokukhetha kwempahla kunaka kakhulu ukuzinza kwesikhathi eside kanye nokumelana nokugqwala. Nakuba i-valve ye-butterfly yesigaba A ilula ngesakhiwo, ingase ibe sengozini yokucekelwa phansi kwezinye izindawo ezinokhahlo.
4. Ukuthenga izinyathelo zokuphepha
Lapho uthenga isigaba A kanye nesigaba B, ama-butterfly valves, lezi zinto ezilandelayo zidinga ukucatshangelwa:
4.1 Izimo zokusebenza: Khetha isigaba esifanele se-butterfly valve ngokuya ngengcindezi yokusebenza, izinga lokushisa, eliphakathi nendawo nezinye izimo zesistimu yamapayipi. Isibonelo, ama-valve e-butterfly esigaba B kufanele anikezwe kuqala ekucindezelweni okuphezulu nasezindaweni zokushisa okuphezulu.
4.2 Izidingo zokusebenza: Izidingo zokusebenza ezicacile, ezidingekayo ukuze uvule futhi uvale ngokushesha, ukusebenza njalo njll., ukukhetha isakhiwo sevalve uvemvane esifanele kanye nemodi yokudlulisela.
4.3 Umnotho: Ngaphansi kwesisekelo sokuhlangabezana nezidingo zokusebenza, cabangela umnotho we-butterfly valve, okuhlanganisa izindleko zokuthenga, izindleko zokunakekela, njll., amavalvu ovemvane esigaba A ngokuvamile anenani eliphansi, kuyilapho isigaba B butterfly valves, nakuba engcono ukusebenza, kungase futhi kube phezulu ngentengo.
