1. Izici zesakhiwo
Kunemehluko osobala phakathi kwevalvu yebhabhathane yesigaba A kanye nevalvu yebhabhathane yesigaba B ngesakhiwo.
1.1 Isigaba A amavalvu ebhabhathane awuhlobo "olugxile", ngokuvamile anesakhiwo esilula, esakhiwe umzimba wevalvu, idiski yevalvu, isihlalo sevalvu, umshafu wevalvu kanye nedivayisi yokudlulisela. Idiski yevalvu inomumo wediski futhi ijikeleza umshafu wevalvu ukulawula ukugeleza koketshezi.
1.2 Ngokuphambene nalokho, ama-valve e-butterfly esigaba B ayizinhlobo "zohlobo lwe-offset", okusho ukuthi i-shaft isuselwe kudiski, iyinkimbinkimbi kakhulu futhi ingaqukatha izimbobo ezengeziwe, izisekelo, noma ezinye izingxenye ezisebenzayo ukuze kuhlinzekwe ukusebenza okukhulu kokuvala nokuzinza.
2. Aizicelo ezimweni ezahlukene zokusebenza
Ngenxa yokwehluka kwesakhiwo, ivalvu yebhabhathane yesigaba A kanye nevalvu yebhabhathane yesigaba B nazo ziyasetshenziswa ezimweni zokusebenza ezahlukene.
2.1 Amavalvu e-butterfly esigaba A asetshenziswa kabanzi ohlelweni lwamapayipi olunomfutho ophansi, olunobubanzi obukhulu, njengokukhipha amanzi, ukungenisa umoya kanye neminye imboni, ngenxa yesakhiwo sawo esilula, usayizi omncane, isisindo esincane kanye nezinye izici.
2.2 I-valve ye-butterfly yesigaba B ifaneleka kakhulu ekusetshenzisweni okusebenzayo okunezidingo eziphezulu zokusebenza kokuvala kanye nomfutho omkhulu ophakathi, njengamakhemikhali, uphethiloli, igesi yemvelo kanye neminye imboni.
3. Ukuqhathaniswa kwenzuzo yokusebenza
3.1 Ukusebenza kokuvala: ama-valve e-butterfly esigaba B ngokuvamile angcono kune-valve ye-butterfly yesigaba A ekusebenzeni kokuvala, ngenxa yesakhiwo sawo esiyinkimbinkimbi kanye nomklamo owengeziwe wokuvala. Lokhu kwenza i-valve ye-butterfly yesigaba B ikwazi ukugcina umphumela omuhle wokuvala ezindaweni ezinzima njengokucindezela okuphezulu kanye nokushisa okuphezulu.
3.2 Umthamo wokugeleza: Umthamo wokugeleza wevalvu yevemvane yesigaba A uqinile, ngoba ukwakheka kwediski yevalvu kulula kakhulu, ukumelana kokudlula koketshezi kuncane. Ivalvu yevemvane yesigaba B ingathinta ukusebenza kahle kokugeleza koketshezi ngezinga elithile ngenxa yesakhiwo sayo esiyinkimbinkimbi.
3.3 Ukuqina: Ukuqina kwamavalvu evemvane esigaba B kuvame ukuba phezulu, ngoba ukwakheka kwawo kanye nokukhethwa kwezinto kunaka kakhulu ukuzinza kwesikhathi eside kanye nokumelana nokugqwala. Nakuba ivalvu yevemvane yesigaba A ilula ngesakhiwo, ingaba sengozini enkulu yokubhujiswa kwezinye izindawo ezinzima.
4. Izinyathelo zokuqapha zokuthenga
Uma uthenga ama-valve e-butterfly esigaba A kanye nesigaba B, lezi zinto ezilandelayo kufanele zicatshangelwe:
4.1 Izimo zokusebenza: Khetha isigaba esifanele sevalvu yevemvane ngokuya ngengcindezi yokusebenza kwayo, izinga lokushisa, isilinganiso kanye nezinye izimo zesistimu yamapayipi. Isibonelo, amavalvu evemvane esigaba B kufanele anikezwe kuqala ezindaweni ezicindezelayo nezishisa kakhulu.
4.2 Izidingo zokusebenza: Izidingo zokusebenza ezicacile, njengokudingekayo ekuvuleni nasekuvaleni okusheshayo, ukusebenza njalo njalo njll., ukuze ukhethe isakhiwo se-butterfly valve esifanele kanye nemodi yokudlulisela.
4.3 Umnotho: Ngaphansi kwesisekelo sokuhlangabezana nezidingo zokusebenza, cabanga ngomnotho wevalvu yevemvane, okuhlanganisa nezindleko zokuthenga, izindleko zokulungisa, njll., amavalvu evemvane esigaba A avame ukuba phansi ngentengo, kuyilapho amavalvu evemvane esigaba B, nakuba esebenza kangcono, nawo angase abe phezulu ngentengo.
