IValve yeBhola eWeld ngokupheleleyo
Ingcaciso yeMveliso
Ibhola yevalve yebhola edadayo ixhaswa ngokukhululekileyo kwiringi yokutywina. Phantsi kwentshukumo yoxinzelelo lolwelo, idityaniswe ngokusondeleyo neringi yokutywina esezantsi ukuze yenze isiphithiphithi esisezantsi sotywino olusecaleni.
Ibhola yevalve yebhola elungisiweyo ene-shaft ejikelezayo enyukayo nasezantsi, igxininiswe kwindawo yokuthwala ibhola, ke ngoko, ibhola igxininisiwe, kodwa umsesane wokutywina uyadada, umsesane wokutywina kunye noxinzelelo lwentwasahlobo kunye nolwelo kwibhola, isiphelo esinyukayo sebhola. itywina.Isetyenziselwa uxinzelelo oluphezulu kunye nezicelo ezinkulu zecaliber.
Inxalenye yokuqhuba yevalve ngokwesakhiwo sevalve kunye neemfuno zomsebenzisi, usebenzisa isibambo, i-turbine, umbane, i-pneumatic, njl., inokusekelwe kwimeko yangempela kunye neemfuno zomsebenzisi ukukhetha indlela efanelekileyo yokuqhuba.
Olu chungechunge lweemveliso zevalve yebhola ngokwemeko ephakathi kunye nombhobho, kunye neemfuno ezahlukeneyo zabasebenzisi, uyilo lokuthintela umlilo, i-anti-static, njengesakhiwo, ukuchasana nobushushu obuphezulu kunye nobushushu obuphantsi kunokuqinisekisa i-valve phantsi kweemeko ezahlukeneyo zihlala. umsebenzi, isetyenziswa ngokubanzi irhasi yendalo, i-oyile, ishishini imichiza, metallurgy, ukwakhiwa ezidolophini, ukhuselo lokusingqongileyo, amayeza, ukutya kunye namanye amashishini.
