Ukungalungi kwe-valve ye-rubber seal butterfly kukuba xa isetyenziselwa i-throttling, i-cavitation iya kwenzeka ngenxa yokusetyenziswa okungafanelekanga, okubangela ukuba isihlalo se-rubber sihlambuluke kwaye sonakalise.Ngenxa yesi sizathu, iivalve ze-butterfly ezitywinwe ngentsimbi ziye zaphuhliswa kumazwe ngamazwe, kwaye indawo ye-cavitation iyancipha.Kwiminyaka yakutshanje, ilizwe lam liye lavelisa izivalo zebhabhathane ezitywinwe ngentsimbi.EJapan, iivalve zebhabhathane ezimilise okwekama ezinokumelana ne-cavitation, ukungcangcazela okuphantsi kunye nengxolo ephantsi ziye zaphuhliswa kwiminyaka yakutshanje.
Ngokuqhelekileyo, ubomi besihlalo sokutywina i-butterfly valve yiminyaka eyi-15-20 yerabha kunye ne-80-90 iminyaka yesinyithi phantsi kweemeko eziqhelekileyo.Nangona kunjalo, ukhetho oluchanekileyo luxhomekeke kwiimfuno zeemeko zokusebenza.
Ubudlelwane phakathi kwedigri yokuvula ivalve yebhabhathane yokutywina yentsimbi kunye nesantya sokuhamba ngokusisiseko sitshintsha ngokulandelelana.Ukuba isetyenziselwa ukulawula ukuhamba, iimpawu zayo zokuhamba nazo zihambelana ngokusondeleyo nokumelana nokuhamba kombhobho.Ngokomzekelo, imibhobho emibini ifakwe kunye nobubanzi obufanayo bevalve kunye nefom, kodwa i-coefficient yokulahlekelwa kombhobho yahlukile, kwaye izinga lokuhamba kwevalve liya kwahluka kakhulu.Ukuba i-valve ikwimeko enoluhlu olukhulu lwe-throttle, umva weplate ye-valve ixhomekeke kwi-cavitation, enokonakalisa i-valve.Ngokuqhelekileyo, isetyenziswe ngaphandle kwe-15 °.
Xa uhlengahlengiso lwentsimbi yebhabhathane itywina lukwindawo ephakathi yokuvula, imilo yokuvula eyenziwe ngumzimba wevalvu kunye nencam yangaphambili yepleyiti yebhabhathane igxile kwi-valve shaft, kwaye amacala amabini abunjwa ukuze agqibezele amazwe ahlukeneyo.Incam engaphambili yepleyiti yebhabhathane kwelinye icala iya kwicala lamanzi aqukuqelayo, kwaye elinye icala liqukuqela ngasemva.Ke ngoko, elinye icala lomzimba wevalve kunye nepleyiti yevalve yenza ukuvulwa okufana nombhobho, kwaye elinye icala lifana nokuvula i-throttle.Icala lombhobho linesantya sokuqukuqela esikhawuleza kakhulu kunecala le-throttle, kwaye ivalve yecala le-throttle iya kuvelisa i-negative Uxinzelelo, izitywina zerabha zihlala ziwe.
I-torque esebenzayo yohlengahlengiso lwebhabhathane yentsimbi inamaxabiso ahlukeneyo ngenxa yokuvula nokuvala ukwahluka kweendlela zevalve.Ivalve yebhabhathane ethe tyaba, ngakumbi i-valve yebhabhathane enobubanzi obukhulu, ngenxa yobunzulu bamanzi, i-torque eveliswa ngumahluko phakathi kweentloko zamanzi aphezulu nasezantsi e-valve shaft ayinakuhoywa.Ukongezelela, xa i-elbow ifakwe kwicala lokungena kwi-valve, ukuhamba kwe-bias kwenziwa kwaye i-torque iya kwanda.Xa i-valve iphakathi kokuvula, indlela yokusebenza kufuneka izivalele ngenxa yesenzo se-torque yamanzi.

I-Nortech ngomnye wabavelisi abakhokelayo bevalvu yeshishini e-China kunye nesiqinisekiso somgangatho we-ISO9001.
