Izivalo Zensimbi Ezithathu Ezisezingeni Eliphezulu Ezine-Eccentric Ze-Triple Offset Butterfly Valve Wafer En Pn16/25/40/63/100
Iyini i-Triple offset butterfly valve wafer?
I-valve ye-butterfly ephindwe kathathu ehlanganisiwe, 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.
I-valve ye-butterfly ephindwe kathathu ehlanganisiwe(eyaziwa nangokuthi i-triple offset butterfly valve) yasungulwa kulokhu.
Kunezici eziningi ze-I-valve ye-butterfly ephindwe kathathu ehlanganisiwe.Kukhona isihlalo se-valve esihambisana nomzimba, esinama-engeli ezihlalo alungiselelwe kahle, esimbozwe ngezinto ezingagqokwa ezifanele izigidi zokuvula nokuvala, insimbi engagqwali yokumelana nokugqwala, kanye nezinto zokushisa okuphezulu. Futhi indandatho yokuvala ethambile enezingqimba eziningi noma indandatho yokuvala eqinile inamathele kudiski yebhabhathane.
ukuvuza okungenalutho kwe- I-valve ye-butterfly ephindwe kathathu ehlanganisiweisetshenziswa 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.
Idizayini ye-wafer ye-butterfly offset 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-I-valve ye-butterfly ephindwe kathathu ehlanganisiwe. Luhlobo lwevalvu yebhabhathane esebenza kahle kakhulu esetshenziswa njengamanje emikhakheni eminingi.
Izici eziyinhloko ze-Triple offset butterfly valve wafer
- Ukwakhiwa kwensimbi yonke okumelana nomlilo.
- Izimbozo zezihlalo ze-Stellite® zebanga lesi-6 zinikeza ukuqina okuhle kakhulu.
- 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.
