Emkhakheni wamavalvu ezimboni, amavalvu amavemvane asetshenziswa kabanzi ezimbonini ezahlukene ezifana namafutha negesi, ukwelashwa kwamanzi, ukucubungula amakhemikhali, njll. Phakathi kwezinhlobo ezahlukene zamavalvu amavemvane, izinhlobo ezimbili zihola phambili: ivalvu yamavemvane e-eccentric ephindwe kabili kanye nevalvu yamavemvane e-eccentric ephindwe kathathu. Kulokhu kuqhathanisa okuphelele, sizobheka ngokujulile ukwakheka, izinzuzo, ukungalungi kanye nokusetshenziswa kwalawa mavalvu amabili.
I-valve yebhabhathane eliphindwe kabili
Njengoba igama lisikisela, amavalvu e-butterfly aphindwe kabili aneziphazamiso ezimbili: i-offset yokuqala iwukungabonakali kwe-shaft, okungukuthi, i-offset ye-axis ye-shaft kusukela enkabeni yepayipi, kanti i-offset yesibili iwukungabonakali kwe-seal, okungukuthi, i-geometry ye-valve disc seal. Lo mklamo unezinzuzo ezinkulu kanye nokungalungi.
Izinzuzo zevalvu yebhabhathane ephindwe kabili
1. Ukuncipha kokuguguleka
Inhloso yomklamo wokungajwayelekile komgodi ukunciphisa ukungqubuzana phakathi kwepuleti levalvu nesihlalo sevalvu ngesikhathi senqubo yokuvula nokuvala, ngaleyo ndlela kuncishiswe ukuguguleka futhi kuncishiswe ingozi yokuvuza. Kungandisa futhi impilo yevalvu yevelufa futhi kuncishiswe izindleko zokulungisa.
2. Ukuvalwa okuthuthukisiwe
Ukuqina kwesibili kwenza indawo yokuvala ithinte isihlalo se-valve kuphela esigabeni sokugcina sokuvala, okungagcini nje ngokuqinisekisa ukuvalwa okuqinile, kodwa futhi kulawula ngempumelelo i-medium.
3. I-torque encishisiwe
Umklamo we-double offset unciphisa i-friction coefficient, okunciphisa amandla adingekayo ukuvula nokuvala i-butterfly valve.
4. Ukuvalwa kwezinhlangothi ezimbili
Amavalvu ebhabhathane aphindwe kabili anganikeza ukuvalwa kwezinhlangothi zombili, okuvumela ukugeleza kwezinhlangothi zombili, futhi kulula kakhulu ukuwafaka nokusebenzisa.
Izinkinga zama-valve e-butterfly aphindwe kabili:
1. Izindleko eziphezulu
Umklamo othuthukisiwe kanye nezinto zokwakha amavalvu ebhabhathane aphindwe kabili ngokuvamile kuholela ezindleleni zokukhiqiza eziphakeme uma kuqhathaniswa namavalvu ebhabhathane aphakathi nendawo.
2. Ukwehla kwengcindezi yamanzi eningi
Ngenxa yepuleti levalvu eliphindwe kabili elijiyile, isihlalo sevalvu esiphumayo, kanye nezindlela ezincane, umfutho wamanzi olahlekelwa yivalvu yebhabhathane ungakhuphuka.
3. Ububanzi bokushisa obulinganiselwe
Amavalvu ebhabhathane aphindwe kabili angancishiswa lapho kuphathwa izinga lokushisa eliphansi kakhulu noma izinga lokushisa eliphezulu ngoba izinto ezisetshenziswayo zingase zingabi namandla okumelana namazinga okushisa aphezulu.
Ivalvu yebhabhathane elingaphandle kathathu
Ivalvu yebhabhathane eliyi-triple offset imelela intuthuko eyengeziwe yomklamo wevalvu yebhabhathane eneziphazamiso ezintathu. Ngokusekelwe kokungajwayelekile okuphindwe kabili, ukungajwayelekile kwesithathu ukuphazamiswa kwe-axis uma kuqhathaniswa nesikhungo somzimba wevalvu. Lo mklamo omusha uyinzuzo eyingqayizivele kunevalvu yebhabhathane yendabuko ephakathi nendawo.
Izinzuzo zamavalvu e-butterfly aphindwe kathathu
1. Akukho ukuvuza
Isimo esiyingqayizivele sesici sokuvala sevalvu yebhabhathane eliyi-triple eccentric siqeda ukungqubuzana nokuguguleka, okuholela ekuvalekeni okuqinile kuyo yonke impilo yevalvu.
2. Ukushisa okuphezulu kanye nokumelana nokucindezela okuphezulu
Kokubili ivalvu yebhabhathane eliyinsimbi yonke kanye nevalvu yebhabhathane eliyi-multi-layer triple eccentric lingakwazi ukusingatha izinga lokushisa eliphezulu kanye noketshezi olunomfutho ophezulu.
3. Umklamo ongashi
Zonke izinto zevalvu yebhabhathane engavamile kathathu zingahlangabezana nezindinganiso eziqinile ezingashi, okwenza kube ngcono kakhulu ekusetshenzisweni okungashi.
4. I-torque ephansi kanye nokungqubuzana
I-valve ye-butterfly eccentric kathathu inganciphisa kakhulu i-torque yokusebenza kanye nokungqubuzana, ngaleyo ndlela ifinyelele ukusebenza okubushelelezi, inciphise i-torque futhi yandise impilo yesevisi.
5. Uhla olubanzi lwezicelo
I-valve ye-butterfly eccentric kathathu ifanelekela izinhlelo zokusebenza ezahlukahlukene, okuhlanganisa uwoyela negesi, i-petrochemical, izimboni zokuphehla ugesi kanye nezokuhlanza.
Izinkinga zamavalvu e-butterfly aqinile kathathu
1. Izindleko eziphezulu
Ivalvu yebhabhathane eliyi-triple eccentric ivame ukuba nezindleko eziphezulu zokukhiqiza kokuqala ngenxa yomklamo wayo othuthukisiwe kanye nesakhiwo.
2. Ukulahlekelwa ikhanda okuphezulu kancane
Ukwengezwa okwengeziwe ekwakhiweni kwe-eccentric kathathu kungabangela ukulahlekelwa kwekhanda okuphezulu kancane kune-valve eccentric ephindwe kabili.
Ivalvu yebhabhathane ephindwe kabili engavamile VS ivalvu yebhabhathane ephindwe kathathu engavamile
1. Isihlalo sevalvu
Isihlalo sevalvu sevalvu yebhabhathane ephindwe kabili ngokuvamile sifakwe emseleni osepuletini levalvu futhi senziwe ngerabha efana ne-EPDM, ngakho-ke singagcina isivalo singangeni moya, kodwa asifanele ukusetshenziswa kwezinga lokushisa eliphezulu kakhulu. Isihlalo sevalvu sevalvu yebhabhathane ephindwe kathathu singensimbi noma sinezingqimba eziningi, ngakho-ke sifaneleka kakhulu ezitsheni ezishisa kakhulu noma ezibolayo.
2. Izindleko
Kungakhathaliseki ukuthi izindleko zokuklama noma inqubo yokukhiqiza iyinkimbinkimbi, amavalvu ebhabhathane aphindwe kathathu aphezulu kunamavalvu ebhabhathane aphindwe kathathu. Kodwa-ke, imvamisa yokulungiswa kwamavalvu ebhabhathane aphindwe kathathu iphansi kuneyamavalvu ephindwe kathathu.
3. I-Torque
Inhloso yokuqala yomklamo wevalvu yebhabhathane eliyi-triple eccentric iwukunciphisa kakhulu ukuguguleka nokungqubuzana. Ngakho-ke, i-torque yevalvu yebhabhathane eliyi-triple eccentric incane kuneyevalvu yebhabhathane eliyi-double eccentric.
