Ivalvu yeButterfly ephindwe kabini ehleli phantsi
Zithini iivalvu zebhabhathane ezingaqhelekanga ezimbini?
Ivalvu yeButterfly ephindwe kabini engaqhelekangayimveliso 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.
Isangqa sokutywina sevalvu yebhabhathane engaqhelekanga kabini senziwe nge-elastomer efakwe kwidiski, ifumaneka kwisicelo sokutywina esingacwangciswanga, isetyenziswa kakhulu emanzini okanye kwisixhobo samanzi sikamasipala.
Into eyenza yahluke kwezinye iivalvu zebhabhathane, yidizayini yediski ephindwe kabini okanye ephindwe kabini.
Ivumela idiski ukuba isuke esihlalweni, nto leyo enciphisa i-torque yokubaleka kunye nokuguguleka kwesihlalo, yinzuzo enkulu xa ithelekiswa neevalvu zebhabhathane eziqinileyo.
Iivalvu zebhabhathane ezijijekileyo ezimbini, ezineringi yokutywina eqiniswe ngepleyiti yokugquma, ziya kwenza ivalvu ibe nomphezulu wokuzinza ongapheliyo kwisangqa kwaye zenze ivalvu ingachukumisi isihlalo kwaphela xa ivuliwe ngokupheleleyo. Olu yilo luya kwenza isihlalo singabi nangxaki ingako kwaye ngokufanelekileyo luya kwandisa ubomi baso. Kwindlela eqhelekileyo, le valve yebhabhathane elungelelaniswe kwicala ngalinye inqunyelwe kwiklasi ye-150.

Qulawulo lomgangatho kwiqhekeza ngalinye levalvu yebhabhathane
Iimpawu eziphambili ze Iivalvu zebhabhathane ezi-eccentric ezimbini zerabha ehleli phantsi:
Ubomi benkonzo ende ngenxa yediski ethambekileyo
Uxinzelelo kwidiski lukhutshwa emva kokuvulwa okuncinci okunciphisa ukuguguleka kwetywina lediski. Ngaphezu koko, uyilo lunciphisa ukucinezelwa kwetywina okuqinisekisa ukuba ii-torque ezisebenzayo ziphantsi.
Uyilo lwezihlalo ezimbini
Uyilo lwesihlalo esidibeneyo lunesihlalo sentsimbi esifakwe ngomatshini nesigqunywe nge-epoxy esidityaniswe emzimbeni. Uyilo lwesihlalo sentsimbi engagqwaliyo luneringi yesihlalo enokutshintshwa eyenziwe ngentsimbi engagqwaliyo etywinwe nge-O-ring ukuze kuthintelwe ukuvuza phantsi kweringi yesihlalo.
Iimpawu zoyilo lwe-shaft
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.
Itywina lediski lenzelwe ukusebenza kakuhle
I-disc seal yenzelwe ukuba iqine kakuhle kwindawo echanekileyo, inika umsebenzi othembekileyo kakhulu. Umgangatho werabha ogqwesileyo wenza kube nokwenzeka ukunciphisa ubungakanani berabha, nto leyo eqinisekisa ukuba i-torque yokuvala iphantsi. I-EPDM seal ivunyiwe yi-ACS kunye ne-WRAS.
Ukuqina kwecala eliphakathi
Iivalvu zibhekisa kwicala elinye kwaye zibhekisa kwicala elinye xa ufuna uncedo.
Itywina elinokutshintshwa kwidiski elinokulungiswa okungayekiyo
Uyilo lwe-Ddouble offset lubangela ukuba izihlalo zingagugi kakhulu, i-torque iphantsi
Ukungqubana okuncinci kuqinisekisa ubomi bokusetyenziswa ixesha elide
Indandatho yokutywina evuselelekayo
Umzimba wepeyinti ye-Epoxy kunye nediski
I-flange ephezulu ye-ISO 5211 yokusebenza ngeendlela ezahlukeneyo
Akukho kuvuza kumacala omabini
Uhlobo Lokusebenza Kwerabha Yesigqubuthelo Sebhabhathane Esine-Double Eccentric Eccentric Ehleliyo
ngenxaIivalvu ezimbini ze-buttefly ezingaqhelekanga zerabha ezihleli phantsi, sibonelela
Ukusebenza kwebhokisi yegiya ngesandla, i-actuator ye-pneumatic, i-actuator yombane, kunye nee-actuator ze-hydraulic ukhetho lwakho.
