Emkhakheni wama-valve ezimbonini, ama-butterfly valves asetshenziswa kakhulu ezimbonini ezihlukahlukene ezifana nowoyela negesi, ukwelashwa kwamanzi, ukucubungula amakhemikhali, njll. Phakathi kwezinhlobo ezahlukene zamavalve ovemvane, kukhona okubili okuhamba phambili: i-butterfly valve eccentric kabili kanye ne-eccentric kathathu. uvemvane valve.Kulesi siqhathaniso esibanzi, sizobheka ngokujulile ukuklama, izinzuzo, ukungalungi kanye nokusetshenziswa kwalawa ma-valve amabili.
I-valve yevemvane ye-Offset kabili
Njengoba igama liphakamisa, ama-valve e-butterfly e-double offset ane-offsets emibili: i-offset yokuqala i-shaft eccentricity, okungukuthi, i-offset ye-axis ye-shaft ukusuka emgqeni ophakathi wepayipi, futhi i-offset yesibili i-eccentricity yophawu, okungukuthi, i-geometry ye-valve disc seal.Lo mklamo unezinzuzo ezibalulekile kanye nokubi.
Izinzuzo ze-valve butterfly eccentric ephindwe kabili
1. Ukugqoka okuncishisiwe
Inhloso yokwakheka kwe-shaft eccentricity ukunciphisa ukungqubuzana phakathi kwepuleti le-valve nesihlalo se-valve phakathi nenqubo yokuvula nokuvala, ngaleyo ndlela kwehliswe ukuguga nokunciphisa ingozi yokuvuza.Ingase futhi inwebe impilo ye-valve uvemvane futhi inciphise izindleko zokunakekela.
2. Ukubekwa uphawu okuthuthukisiwe
I-eccentricity yesibili yenza indawo yokuvala ixhumane nesihlalo se-valve kuphela esigabeni sokugcina sokuvala, esingaqinisekisi kuphela uphawu oluqinile, kodwa futhi lulawula ngokuphumelelayo okuphakathi.
3. I-torque encishisiwe
Umklamo we-double offset wehlisa i-coefficient yokungqubuzana, okunciphisa amandla adingekayo ukuze uvule futhi uvale i-valve uvemvane.
4. Ukubekwa uphawu kabili
Amavalvu ovemvane ane-eccentric ephindwe kabili angahlinzeka ngokuvala okuqondisayo kabili, okuvumela ukugeleza okukabili, futhi kulula kakhulu ukukufaka nokusetshenziswa.
Ububi be-double eccentric butterfly valves:
1. Izindleko eziphakeme
Idizayini ethuthukisiwe nezinto zokwakha zamavalvu ovemvane ane-eccentric kabili ngokuvamile kubangela izindleko zokukhiqiza eziphakeme uma kuqhathaniswa namavalvu ovemvane aphakathi nendawo.
2. Umfutho wamanzi owengeziwe ulahlekelwa
Ngenxa yokuqina kwepuleti le-valve ye-eccentric ephindwe kabili, isihlalo se-valve egqamile, namaphaseji amancane, umfutho wamanzi olahlekelwa yivalve uvemvane ungase unyuke.
3. Ibanga lokushisa elilinganiselwe
Amavalvu evemvane eccentric kabili angase akhawulelwe lapho uphatha izinga lokushisa eliphansi kakhulu noma imidiya yezinga lokushisa eliphezulu ngenxa yokuthi izinto ezisetshenziswayo zingase zingamelani nezinga lokushisa elidlulele.
Ivalve uvemvane ye-Offset kathathu
Ivalvu yevemvane ephindwe kathathu imelela ukuthuthukiswa okuqhubekayo komklamo we-butterfly valve enama-offset amathathu.Ngesisekelo se-eccentric ephindwe kabili, i-eccentricity yesithathu i-offset ye-axis uma kuqhathaniswa nendawo ephakathi komzimba we-valve.Lo mklamo omusha uyinzuzo eyingqayizivele ngaphezu kwevalve uvemvane ephakathi nendawo.
Izinzuzo zama-valve evemvane eccentric kathathu
1. Ukuvuza okunguziro
Umumo oyingqayizivele wesici sokuvala se-valve uvemvane eccentric kathathu uqeda ukungqubuzana nokuguga, okuholela ekuvaleni okuqinile kukho konke ukuphila kwe-valve.
2. Ukushisa okuphezulu nokumelana nokucindezela okukhulu
Kokubili i-valve uvemvane we-all-metal triple eccentric kanye ne-valve uvemvane enezingqimba eziningi ezintathu ingakwazi ukumelana nezinga lokushisa eliphezulu noketshezi olunomfutho ophezulu.
3. Umklamo ongashi
Zonke izinto zokwakha ze-valve ye-butterfly eccentric kathathu zingahlangabezana nezindinganiso eziqinile zokuvikela umlilo, ziyenze ivelele ekusetshenzisweni komlilo.
4. I-torque ephansi kanye nokungqubuzana
I-valve yevemvane eyi-eccentric eccentric kathathu inganciphisa futhi i-torque yokusebenza kanye nokungqubuzana, ngaleyo ndlela ifeze ukusebenza kahle, inciphise i-torque futhi inwebe impilo yesevisi.
5. Uhlu olubanzi lwezinhlelo zokusebenza
I-valve ye-butterfly eccentric kathathu ilungele ukusetshenziswa okuhlukahlukene, okuhlanganisa uwoyela negesi, i-petrochemical, ukukhiqiza amandla kanye nezimboni zokucwenga.
Ukungalungi kwama-valve evemvane eccentric kathathu
1. Izindleko eziphakeme
Ivalvu yevemvane eyi-triple eccentric ivame ukuba nezindleko zokukhiqiza eziphakeme ngenxa yokwakheka kwayo okuthuthukile kanye nesakhiwo.
2. Ukulahlekelwa ikhanda kancane
I-offset eyengeziwe ekwakhiweni kwe-eccentric kathathu ingase ibangele ukulahlekelwa kwekhanda okuphakeme kancane kune-valve ye-eccentric ephindwe kabili.
I-valve uvemvane ene-eccentric ephindwe kabili VS ivalve uvemvane oluphindwe kathathu
1. Isihlalo se-valve
Isihlalo se-valve se-valve uvemvane eccentric kabili ngokuvamile sishunyekwa ku-groove ku-valve plate futhi senziwe ngerabha efana ne-EPDM, ukuze sifinyelele uphawu olungangeni moya, kodwa asifanele ukusetshenziswa kwezinga lokushisa eliphezulu.Isihlalo sevalvu se-valve yevemvane eyi-eccentric kathathu siyinsimbi yonke noma enezingqimba eziningi, ngakho-ke sifaneleka kakhulu izinga lokushisa eliphezulu noma uketshezi olubolayo.
2. Izindleko
Kungakhathaliseki ukuthi izindleko zokuklama noma inkimbinkimbi yenqubo yokukhiqiza, ama-valve evemvane eccentric kathathu aphakeme kunama-valve uvemvane ane-eccentric kabili.Kodwa-ke, imvamisa yokugcinwa kwangemuva kokugcinwa kwama-valve eccentric kathathu iphansi kunaleyo yama-valve eccentric kabili.
3. Torque
Inhloso yasekuqaleni yedizayini yevalvu uvemvane eccentric kathathu ukwehlisa ukuguga nokungqubuzana.Ngakho-ke, i-torque ye-valve uvemvane eccentric kathathu incane kunaleyo yevalve uvemvane eccentric kabili.
