Ivalufa yebhabhathane ene-Eccentric ephindwe kabini
Yintoni iValve yebhabhathane eEccentric ephindwe kabini ?
Ivalufa yebhabhathane ene-Eccentric ephindwe kabini yimveliso yoyilo ephindwe kabini eneteknoloji ehamba phambili yehlabathi.Le valve yebhabhathane inesakhiwo esikhethekileyo esinentsebenzo yokutywina ethembekileyo, iimeko ezibanzi zokusebenza kunye netorque ephantsi yokusebenza.
iimpawu eziphambili zeevalvu zebhabhathane eccentric yi-double eccentric, ekwabizwa ngokuba yi-double offset disc design.
ivumela i-disc ukuba ihambe esitulweni inciphisa itorque kunye nokunxiba kwesitulo, yinzuzo enkulu xa kuthelekiswa neevalvu zebhabhathane.
Uxinzelelo kwi-disc lukhutshwa emva kweedigri ezimbalwa zokuvula ezinciphisa ukunxiba kwe-disc seal.Ngapha koko, uyilo lunciphisa ukunyanzeliswa kokutywinwa okuqinisekisa iitorque eziphantsi zokusebenza.
Ukutywinwa kwe-shaft kutshintshwa phantsi koxinzelelo ukwenzela ukuba kube lula ukugcinwa.Ukutywinwa kwe-EPDM kukhuselekile ukuqina ngaphakathi nangaphandle, kwaye ukutywinwa kwe-NBR kukhuseleka kubumdaka kunye nolwelo oluvela ngaphandle.
Ukukhuhlana okuphantsi kweebheringi ze-PTFE ziqinisekisa iitorque zokusebenza eziphantsi kwaye i-shaft ekhuselweyo iphelisa ukuqina okukhuselekileyo kuba kungekho miphezulu yentsimbi edibeneyo engafakwanga evezwe kumajelo eendaba.

- Ukusebenza kwetywina okuthembeke kakhulu: ukuvuza kwe-bi-directional zero
- kulula ukutshintsha isihlalo ngokususa isifakelo, esilungele ukulungiswa.
- Kukho isakhiwo esikhuselekileyo sokuvuthela phezulu kwisiqu
- Iimpawu zohlengahlengiso ezigqwesileyo
- Uyilo lobungqina bomlilo
Ukutywina ubuchule beIvalufa yebhabhathane ene-Eccentric ephindwe kabini
Uhlobo lwe-Stem-upstream
Xa i-media iphuma ngasemva kwevalve yebhabhathane ukuya ngaphambili, ipleyiti yebhabhathane iyazitywina ngenxa yokunyuka kweendaba kunye noxinzelelo lwesihlalo.
Uhlobo lwe-Stem-downstream
Xa ijelo losasazo libaleka lisuka phambi kwevalve yebhabhathane ukuya ngasemva, i-medium yenza i-thrust kwi-engile yangasemva kwesihlalo kwaye ipleyiti yebhabhathane yenza uxinzelelo lokuzitywina.
Uhlobo lokuSebenza lweValve yeButterfly ephindwe kabini
Phatha i-lever yeevalvu zebhabhathane ezomeleleyo DN40-DN200.
Umsebenzisi webhokisi yegiya yoluhlu olupheleleyo lweevalvu zamabhabhathane.
I-actuator ye-pneumatic yoluhlu olupheleleyo lweevalvu zebhabhathane
I-actuator yombane yoluhlu olupheleleyo lweevalvu zebhabhathane
Isiqu sasimahla ngaphandle kwe-activator, eyenzelwe abathengi abanee-activators zakho.

uMboniso weMveliso:
Isetyenziselwa ntoni iValve yeButterfly eEccentric?
Ukwenza okuphezuluivalve yebhabhathane eccentric kabiniizicelo
I-1: Iimeko zokusebenza eziphezulu zesantya esiphezulu: kwinkqubo yokwahlula umoya, inokwenziwa ixesha elide ngaphakathi kwesibini sokutshintsha,
Ubomi bunokufikelela kwi-1 yezigidi zamaxesha
I-2: Iimeko zokusebenza eziphezulu zokushisa: Isihlalo sezinto ze-PPL zifanelekile kubushushu obuphezulu be-250 degrees C.
I-3: Uxinzelelo oluphezulu oluphindwe kabini kwiimeko ezi-6 zokutywinwa: kwinkqubo yokugqiba i-condensate inoluhlu olubanzi lwezicelo.
I-4: Iimeko zokusebenza kwe-oksijeni: Le valve emva kokunyanga kwe-degreasing ingasetyenziselwa iimeko zokusebenza ze-oksijini, kwiindawo
Ngokumalunga nokulungiselela, ukudibanisa, ukuvavanywa kunye nokupakishwa, i-valve ihlanjululwa ngokuhambelana ngokuthe ngqo neenkqubo.
5: Iimeko zevacuum: umgangatho ophezulu wokusebenza (i-double eccentric) ivalve yebhabhathane ireyithwe itywina ukuze kuphunyezwe ivacuum
2x10-2.Iivalve ezikhethekileyo eziphezulu ze-vacuum ezine-vacuum ye-2x10-5 nazo ziyafumaneka.
