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-double eccentric butterfly valve
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 anganikeza ukuvala 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 ovemvane ane-eccentric kabili angase akhawulelwe lapho uphatha izinga lokushisa eliphansi kakhulu noma imidiya yethempelesha ephezulu 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 uvemvane we-eccentric eccentric kathathu zingahlangabezana nezindinganiso eziqinile zokuvikela umlilo, ziyenze ivelele ekusetshenzisweni komlilo.
4. I-torque ephansi kanye nokungqubuzana
I-valve ye-butterfly 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
Ivalve 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 ivalvevemvane ene-eccentric 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.
