I-valve yevemvane eyi-eccentric ephindwe kabili iqanjwe ngezakhiwo zayo ezimbili ezi-eccentric.Ngakho-ke injani i-double eccentric structure?
Okubizwa ngokuthi i-double eccentric, i-eccentric yokuqala ibhekisela ku-valve shaft ephuma phakathi nendawo yokuvala, okusho ukuthi isiqu singemuva kobuso bepuleti le-valve.Lokhu kufiphala kwenza indawo ethintana nayo kokubili ipuleti le-valve nesihlalo se-valve indawo yokuvala, enqoba ngokuyisisekelo ukushiyeka okungokwemvelo okukhona kuma-valve ovemvane agxilile, ngaleyo ndlela kuqede ithuba lokuvuza kwangaphakathi empambanweni yomgwaqo engenhla nephansi phakathi kwe-valve shaft kanye isihlalo se-valve.
Enye i-eccentricity ibhekisela esikhungweni somzimba we-valve kanye ne-stem axis yesokunxele nesokudla, okungukuthi, isiqu sihlukanisa ipuleti uvemvane zibe izingxenye ezimbili, eyodwa ngaphezulu nenye ngaphansi.Lokhu kucacile kungenza ipuleti le-butterfly ekuvuleni nasekuvaleni likwazi ukunqanyulwa ngokushesha noma lisondele eduze kwesihlalo se-valve, kunciphise ukungqubuzana phakathi kwepuleti le-valve nesihlalo se-valve esivaliwe, kunciphise ukuguga, kunciphise ukuvuleka nokuvala ithoshi, futhi wandise impilo yesevisi yesihlalo se-valve.
Amavaluvu Evemvane E-Eccentric Avala Kanjani?
Isiyingi sangaphandle sepuleti levalvu kanye nesihlalo esivalekile se-double eccentric butterfly valve senziwa ngomshini endaweni ene-hemispherical, futhi indawo eyindilinga yangaphandle yepuleti le-valve incindezela indawo engaphakathi eyindilinga yesihlalo esivaliwe ukuze kukhiqizwe ukuwohloka okunwebekayo ukuze kufinyelelwe ukuvala okuvaliwe. isimo.Uphawu lwe-valve uvemvane oluyi-eccentric ephindwe kabili luyingxenye yesakhiwo sokuvala, okusho ukuthi indawo yokuvala ye-valve plate kanye nesihlalo sevalvu sixhumene nomugqa, futhi indandatho yokuvala ngokuvamile yenziwe ngerabha noma i-PTFE.Ngakho-ke ayimelani nokucindezela okuphezulu, futhi isicelo ohlelweni lokucindezela okuphezulu kuzoholela ekuvuzeni.
Ithini Ingxenye Eyinhloko Yevalve Ye-Butterfly Ephindwe Kabili?
Kusukela Esithombeni Ngenhla, Singabona Ngokusobala Ukuthi Izingxenye Eziyinhloko Ze-Double Eccentric Butterfly Valve Ziqukethe Izinto Eziyisikhombisa Ezilandelayo:
Umzimba: Izindlu eziyinhloko ze-valve, ngokuvamile ezenziwe ngensimbi eyinsimbi, i-ductile iron, noma insimbi engagqwali, iklanyelwe ukubeka izingxenye zangaphakathi zevalvu.
I-Disc: Ingxenye emaphakathi yevalvu ezungeza ngaphakathi komzimba wevalvu ukulawula ukugeleza koketshezi.I-disc ngokuvamile yenziwe ngensimbi ekhonjiwe, insimbi ekhonjiwe noma ithusi futhi inomumo oyisicaba noma ogobile ukuze ihambisane nokuma komzimba we-valve.
Ama-Shaft Bearings: ama-shaft bearings atholakala emzimbeni we-valve futhi asekela umgodi, owuvumela ukuthi ujikeleze kahle futhi unciphise ukungqubuzana.
Indandatho yokuvala: indandatho yerabha yokuvala igxilwe epuleti levalvu ngepuleti lokucindezela nezikulufu zensimbi engagqwali, futhi isilinganiso sokuvala amavalvu silungiswa ngokulungisa izikulufu.
Isihlalo Sokuvala: siyingxenye yevalvu evala idiski futhi igweme ukuvuza koketshezi ngevalvu lapho ivaliwe.
I-Shaft ye-Drive: ixhuma i-actuator ku-flap ye-valve futhi idlulisele amandla ahambisa i-valve flap endaweni oyifunayo.
I-Actuator: ilawula indawo yediski ngaphakathi komzimba wevalvu.Futhi ngokuvamile ogibele phezu umzimba valve.
Umthombo Wesithombe: Hawle
Ividiyo elandelayo inikeza umbono obonakalayo nonemininingwane wedizayini kanye nesici se-valve uvemvane eccentric kabili.
Izinzuzo Nemibi Yevalve Ye-Butterfly Eccentric Ephindwe Kabili
Izinzuzo:
1 Idizayini enengqondo, ukwakheka okuhlangene, kulula ukuyifaka nokuhlakaza, ukusebenza okuvumelana nezimo, ukonga abasebenzi, okulula, nokulungisa kalula.
2 Ukwakheka kwe-eccentric kunciphisa ukungqubuzana kwendandatho yokuvala futhi kwandise impilo yesevisi ye-valve.
3 Kuvalwe ngokuphelele, ukuvuza kwe-zero.Ingasetshenziswa esimweni se-vacuum ephezulu
4 Shintsha impahla ye-valve plate seal, butterfly plate, shaft, njll., engasetshenziswa ezinhlobonhlobo zemidiya namazinga okushisa ahlukene.
5 Isakhiwo sohlaka, amandla aphezulu, indawo enkulu yokuchichima, ukumelana nokugeleza okuncane
Ububi:
Ngenxa yokuthi ukubekwa uphawu kuyisakhiwo sokuvala indawo, indawo yokuvala yepuleti levemvane kanye nesihlalo se-valve kuxhumene nomugqa, futhi ukuvala uphawu kukhiqizwa ukuguqulwa kwe-elastic okubangelwa ipuleti levemvane licindezela isihlalo se-valve, ngakho-ke kudinga ukuvala okukhulu. isikhundla futhi inomthamo ophansi wokucindezela okuphezulu nokushisa okuphezulu.
Ibanga Lokusebenza LeValve Yevemvane Ye-Offset Ekabili:
- Izinhlelo zokuhlanza nokusabalalisa amanzi
- Imboni yezimayini
- Ukwakhiwa kwemikhumbi kanye nezindawo zokumba
- Izitshalo zamakhemikhali kanye ne-petrochemical
- Amabhizinisi okudla namakhemikhali
- Izinqubo zikawoyela negesi
- Isistimu yokucima umlilo
- Amasistimu we-HVAC
- Uketshezi namagesi angenalo ulaka (igesi yemvelo, i-CO-gas, imikhiqizo ye-petroleum, njll.)
