I-GB cast steel Trunnion ball valves : Uhlalutyo olunzulu lwesakhiwo kunye neempawu
Umgangatho wesizwe owenziwe ngentsimbi yentsimbi esisigxina sisixhobo sevalve esisetyenziswa ngokubanzi kwiinkqubo zemibhobho yoshishino. Imigangatho yayo yoyilo ihambelana nemigangatho yelizwe laseTshayina kwaye ineempawu ezithile zesakhiwo kunye neenzuzo zokusebenza. Oku kulandelayo yintshayelelo eneenkcukacha kazwelonke yomgangatho wentsimbi yevalve yebhola esisigxina:
1. Iimpawu zesakhiwo:
-Uphawu oluphambili lwe-valve yebhola esisigxina kukuba ibhola igxininiswe kwaye ayikwazi ukuhamba, kwaye ukutshintshwa kufezekiswa ngokuhamba kwesihlalo sevalve. Olu luyilo lwenza lula ulwakhiwo lwevalve, lwenza umsebenzi uzinze kwaye uthembekile.
-Ukusetyenziswa kwempahla yentsimbi kwandisa ukunyanzeliswa koxinzelelo kunye nokuxhatshazwa kwe-valve, okwenza kube lula kuluhlu olubanzi lweendawo zokusebenza.
2. Iimathiriyeli zecandelo eliphambili:
-Izinto eziphambili zecandelo lomgangatho wesizwe owenziwe ngentsimbi yentsimbi esisigxina i-valve yebhola edibeneyo ibandakanya i-carbon steel, insimbi engenasici, njl.
3. Iindawo zokufaka izicelo:
-Ngenxa yokusebenza kwayo okugqwesileyo kunye nokuthembeka, iivalvu zebhola ezimisiweyo zesizwe ezisemgangathweni zisetyenziswa ngokubanzi kwiinkqubo zemibhobho kumashishini afana nepetroleum, imichiza, kunye negesi yendalo ukulawula ukuhamba kweendaba.
4. Imigangatho yokwenziwa:
-Uyilo, ukuveliswa, kunye nokuvavanya le valve yebhola zenziwa ngokuhambelana nemigangatho yelizwe efana ne-GB / T12237, ukuqinisekisa umgangatho kunye nokusebenza kwemveliso.
5. Ugcino kunye nogcino:
-Hlola rhoqo imeko yokusebenza kwevalve, ucoce ukungcola okuqokelelweyo ngexesha elifanelekileyo, kwaye ugcine ukucoceka kwevalve.
-Ii-valve ezingasetyenziswanga ixesha elide, imisebenzi yokuvula kunye nokuvala rhoqo kufuneka iqhutywe ukukhusela ibhola ekubambeleleni kwisihlalo se-valve.
Isishwankathelo, umgangatho wesizwe owenziwe ngentsimbi yentsimbi esisigxina idlala indima ebalulekileyo kwiinkalo ezahlukeneyo zoshishino ngenxa yesakhiwo esiyingqayizivele kunye nokusebenza okuphezulu. Ukuqonda iimpawu zayo ezisisiseko kunye neendlela zokusetyenziswa kunokunceda ukusebenzisa esi sixhobo ngcono, ukuphucula ukusebenza kakuhle kwemveliso kunye nokhuseleko.
