I-API Aluminium Double/Triple Offset Lug/Wafer/Flange Butterfly Valve Imboni yePetrochemical China ifektri
Iyini i-Triple offset butterfly valve lug?
I-valve ye-butterfly ephindwe kathathu,obeye aziwe njengoivalvu 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.
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.
Umklamo we-valve ye-butterfly ephindwe kathathu
- I-offset yokuqala ukuthi i-valve shaft ingemuva kwe-disc shaft ukuze i-seal ikwazi ukuvala ngokuphelele isihlalo se-valve.
- I-offset yesibili ukuthi umugqa ophakathi we-valve shaft ususwa epayipini kanye nomugqa ophakathi we-valve ukuze kugwenywe ukuphazamiseka kokuvulwa nokuvalwa kwe-valve.
- I-offset yesithathu ukuthi i-axis yekhoni yesihlalo iyaphambuka kusukela enkabeni yeshaft yevalvu, okuqeda ukungqubuzana ngesikhathi sokuvala nokuvula futhi kufinyelele uphawu lokucindezela olufanayo oluzungeze sonke isihlalo.
Lokhu okungenhla yisingeniso se-ivalvu yebhabhathane engavamile kathathu. Luhlobo lwevalvu yebhabhathane esebenza kahle kakhulu esetshenziswa njengamanje emikhakheni eminingi.
Izici eziyinhloko ze-Triple offset butterfly valve lug
- 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.
- Ukupakisha i-gland okunezingcezu ezimbili kanye nokupakisha i-graphite kunciphisa ingozi yokukhishwa kwangaphandle.
- Ukuxhumeka okuqinile kwe-shaft-to-disc ukuze kube nokuqina okuphezulu kwe-shaft.
- Ama-gasket enxeba elijikelezayo, izindandatho zokuvala kanye nokupakisha zingashintshwa ngaphandle kwamathuluzi akhethekile.
- Ama-bearings aqinile amelana nemithwalo ephezulu yokucindezela kanye nokuguguleka.
- Ukuphathwa kwengozi yokukhipha umgodi ngaphakathi nangaphandle kuhambisana nezindinganiso zomhlaba wonke.

Umbukiso Womkhiqizo:
Isicelo: I-valve ye-butterfly ephindwe kathathu
Lolu hlobo lweI-valve ye-butterfly ephindwe kathathu 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.
