I-valve ye-butterfly ephindwe kathathu yekhwalithi ephezulu i-BW China Umkhiqizi/ Umhlinzeki/ ifektri
Iyini ivalvu ye-butterfly ye-Triple offset BW?
I-valve yebhabhathane eliphindwe kathathu i-BW, eyaziwa nangokuthiivalvu yebhabhathane eliphindwe kathathu, uhlobo olulodwa lwamavalvu ebhabhathane asebenza kahle kakhulu, aklanyelwe izimo zokusebenza zomfutho ophezulu, izinga lokushisa eliphezulu, kanye nemvamisa ephezulu yokuvula nokuvala.
Ivalvu yebhabhathane efakwe irabha eqondile, enomklamo ovuthiwe kanye nobuchwepheshe bokukhiqiza, ithembekile ngekhwalithi futhi ibiza kahle. Kodwa ngezicelo ezinzima njengamazinga okushisa aphezulu noma ngezikhathi zokuvula nokuvala eziphezulu, akuvunyelwe ukusebenzisa amavalvu ebhabhathane esihlalo esithambile. Ngakho-ke amavalvu ebhabhathane aqinile, isihlalo sensimbi noma isihlalo se-ceramic, aklanyelwe amazinga okushisa aphezulu, umfutho ophezulu noma amaza aphezulu okuvala okuvulekile, asetshenziswa, kodwa ukusebenza kokuvala kwevalvu yebhabhathane eqinisiwe yendabuko bekulokhu kuyinkinga enkulu.
Ivalvu yebhabhathane eliyi-eccentric kathathu(eyaziwa nangokuthi i-triple offset butterfly valve) yasungulwa kulokhu.
ukuvuza okungenalutho kwe-ivalvu yebhabhathane engavamile kathathuisetshenziswa yindandatho yokuvala yensimbi engagqwali ehlanganisiwe efakwe kwidiski. Umklamo wokujikeleza okune-engeli yesokudla ngaphandle kokungqubuzana kwe-zero usetshenziswa yisimiso esihlukile se-triple eccentric. Iqeda ukungqubuzana phakathi kwesihlalo nendandatho yokuvala ngokujikeleza okungu-90º, I-torque encane isho ukuthi singayiqala i-valve nge-actuator encane, ukuze songe izindleko eziningi kanye nesikhala.
Izici eziyinhloko ze-Triple offset butterfly valve BW
- Ukwakhiwa kwensimbi yonke okumelana nomlilo.
- Izimbozo zezihlalo ze-Stellite® zebanga lesi-6 zinikeza ukuqina okuhle kakhulu.
- Izinkomba zediski evulekile/evaliwe kanye nesikhombisi sendawo yediski yangaphandle kwenza kube lula ukufaka/ukususa izinqubo ku-API 609.
- Indandatho yokuvala yensimbi ehlanganisiwe iqinisekisa ukusatshalaliswa okuphelele kwamandla okuhlala eduze komjikelezo wesihlalo oqondile.
- Ukubukeka kwe-flange spot kuqinisekisa ukulingana kwe-bolting nut kanye ne-washer, okwandisa ukuthembeka nokuphepha kwamalunga.
- Izindandatho zokuvala ze-duplex ne-graphite ezinezingqimba eziningi ezithathelwa indawo kalula.
- Umgodi oqiniswe kakhulu onengxenye eyodwa oklanyelwe ukudlulisa/ukugcina i-torque kahle.
- Izivikelo ze-graphite bearing ezilukiwe zivimbela ukungena kokungcola, ziqinisekisa i-torque esebenza njalo kanye nokusebenza kahle kwe-valve.

Umbukiso Womkhiqizo: I-valve ye-butterfly ephindwe kathathu i-BW
Isicelo: I-valve ye-butterfly ephindwe kathathu i-BW
Lolu hlobo lwe-Triple offset butterfly valve BW ifanele ukuphatha uketshezi oluhlukahlukene ku-oyela negesi, i-petrochemical, i-chemical, i-coal, i-desalination, i-waterworks, izimboni zokudla neziphuzo. Futhi ingasetshenziswa elangeni, elangeni kanye nelamanzi, elamandla okushisa komhlaba kanye nelamanzi, amafutha asetshenziswa ezindaweni ezishisayo, ekufudumaleni kwesifunda, ezimayini, ezindaweni zokupaka imikhumbi kanye nasemkhakheni wezindiza.
