Umgangatho ophezulu weeBellows ezitywinwe iValve yeGlobe
GW Bellow ivalve yeglowubhu yetywina
Umsebenzi wevalvu yeglowubhu yetywina kukutywina kunye nokuthintela okuphakathi ekuvuzeni kwesikhondo sevalvu.Isiphelo esisezantsi se-bellows sidityaniswe nesiqu sevalve ngokutywinwa kwe-welding, kwaye isiphelo esiphezulu sidityaniswe nedlala ngokutywinwa kwe-welding.Ngokubanzi, i-metal spiral wound gasket ifakwe phakathi kwedlala kunye neflange ephezulu ukuqinisekisa ukutywinwa.Ivalve yeglowubhu ye-bellows itywina inokusebenza okuqinileyo, kwaye ayifane ivuze.
Umda wesicelo: i-petroleum, ishishini lemichiza, ishishini lamayeza, isichumisi sekhemikhali, ishishini lamandla ombane, njl.

1. Ivalve yokumisa i-Bellows, icandelo layo elingundoqo lemivungu yentsimbi, isiphelo esisezantsi kunye ne-valve stem indibano yamkele i-welding ye-welding ezenzekelayo, kwaye isiphelo esiphezulu sidityaniswe ngokuzenzekelayo ngepleyiti yokudibanisa ukuze yenze umqobo wesinyithi phakathi kwendawo yolwelo kunye nomoya ukuya. qinisekisa ukuvuza kweqanda kwisiqu sevalvu.
2. I-Valve disc ithatha uyilo oluhambelanayo, isiphumo esingcono sokutywinwa kunye nobomi benkonzo ende.
3. Uyilo olutywiniweyo oluphindwe kabini (imvubelo + ukupakishwa) kwimeko yokungaphumeleli kwemivumbo kunye nokuvuza, ukupakishwa kwesikhondo sevalve kuya kuthintela ukuvuza kwaye kuhambelane nomgangatho wokutywinwa wamazwe ngamazwe.
4. Isigqubuthelo sevalve sixhotyiswe ngokudityaniswa kwegrisi, esinokuthambisa ngokuthe ngqo i-valve stem, i-nut kunye nomkhono we-shaft, ngokungafaniyo nendlela yendabuko yokuthambisa intambo kuphela.
5. I-Ergonomic design handwheel, ubomi benkonzo ende, kulula kwaye kulula ukusebenza, ikhuselekile kwaye inokwethenjelwa.
