Ivalvu yeButterfly ephindwe kabini engaqhelekanga
Yintoni iValve yeButterfly eNcinci eBini?
Ivalvu yeButterfly ephindwe kabini engaqhelekanga yimveliso yoyilo oluyintsha oluphindwe kabini oluneteknoloji ephambili kwihlabathi liphela. Le valve yebhabhathane inesakhiwo esahlukileyo esinokusebenza okuthembekileyo kakhulu kokutywina, iimeko zokusebenza ezibanzi kunye ne-torque ephantsi yokusebenza.
Iimpawu eziphambili zeevalvu zebhabhathane ezi-eccentric eziphindwe kabini yi-eccentric ephindwe kabini, ekwabizwa ngokuba yi-double offset disc design.
Ivumela idiski ukuba isuke esihlalweni, nto leyo enciphisa i-torque yokubaleka kunye nokuguguleka kwesihlalo, yinzuzo enkulu xa ithelekiswa neevalvu zebhabhathane eziqinileyo.
Uxinzelelo kwidiski lukhutshwa emva kokuvulwa okuncinci okunciphisa ukuguguleka kwetywina lediski. Ngaphezu koko, uyilo lunciphisa ukucinezelwa kwetywina okuqinisekisa ukuba ii-torque ezisebenzayo ziphantsi.
Ukutywinwa kweshaft kunokutshintshwa xa kucinezelwe ukuze kube lula ukugcinwa. Ukutywinwa kwe-EPDM kuqinisekisa ukuqina ngaphakathi nangaphandle, kwaye ukutywinwa kwe-NBR kukhusela ukungcola kunye nolwelo oluvela ngaphandle.
Iibheringi zePTFE ezixineneyo nezinoxinzelelo oluphantsi ziqinisekisa ukuba ii-torque ezisebenzayo ziphantsi kwaye iziphelo zeshaft ezikhuselweyo ziqinile kuba akukho zindawo zentsimbi ezingagqunywanga ezivezwa kwimidiya.

- Uyilo olungenamlilo
Ubuchule bokuvalaIvalvu yeButterfly ephindwe kabini engaqhelekanga
Uhlobo lweStem-upstream
Xa i-media iphuma ngasemva kwe-butterfly valve iye ngaphambili, i-butterfly plate iyazivala ngenxa yokutyhala phezulu kwe-media kunye noxinzelelo lwesihlalo.
Uhlobo lwe-Stem-downstream
Xa i-media iphuma ngaphambili kwevalvu yebhabhathane iye ngasemva, i-medium ivelisa i-thrust kwi-engile yangasemva kwesihlalo kwaye ipleyiti yebhabhathane yenza i-pressure self-sealing
Uhlobo Lokusebenza lweValve yeButterfly eNcinci eBini
Isixhobo sokuphatha iivalvu zebhabhathane ezihlala ziqinile DN40-DN200.
Umqhubi webhokisi yegiya ngesandla yeevalvu zebhabhathane ezisebenzisa uluhlu olupheleleyo.
I-actuator ye-pneumatic yoluhlu olupheleleyo lweevalvu zebhabhathane
Isixhobo sombane sokukhetha uluhlu olupheleleyo lweevalvu zebhabhathane
Isiqu sasimahla esingena-actuator, senzelwe abathengi abane-actuators zakho.

Umboniso weMveliso:
Isetyenziselwa ntoni iValve yeButterfly eDual Eccentric?
Ukwenza okuphezuluivalvu yebhabhathane engaqhelekanga kabiniizicelo
1: Iimeko zokusebenza ezikhawulezayo kakhulu: kwinkqubo yokwahlula umoya, ingenziwa ixesha elide ngaphakathi kweswitshi yesekhondi e-1,
Ubomi bunokufikelela kwi-1 yezigidi
2: Iimeko zokusebenza ezinobushushu obuphezulu: Isihlalo sezinto zePPL sifanelekile kumaqondo obushushu aphezulu angama-250 degrees C.
3: Iimeko zokutywina ezinamacala amabini ezixineneyo ezinezigaba ezi-6: kwinkqubo yokugqiba i-condensate inezicelo ezininzi.
4: Iimeko zokusebenza kweoksijini: Le valve emva konyango lokususa amafutha ingasetyenziselwa iimeko zokusebenza kweoksijini, kwiindawo ezithile
Ngokuphathelele ukulungiswa, ukuhlanganiswa, ukuvavanywa kunye nokupakishwa, ivalvu icocwa ngokuhambelana neenkqubo ezimiselweyo.
5: Iimeko zokukhupha umoya: ivalvu yebhabhathane esemgangathweni esebenza kakuhle (ephindwe kabini) elinganiswe ngexabiso lokuvala umoya ukuze kufunyanwe ivasi
2x10-2. Iivalvu ezikhethekileyo ze-vacuum eziphezulu ezine-vacuum ye-2x10-5 nazo ziyafumaneka.
