I-GB Forged Steel Trunnion Ball Valves: Uhlalutyo olunzulu lwesakhiwo kunye neempawu
Umgangatho wesizwe owenziweyo wentsimbi yevalve yebhola esisigxina sisixhobo sevalvu yoshishino enoyilo olugqwesileyo kunye nokusebenza okuphezulu. Uyilo kunye nokuveliswa kwayo kuhambelana ngokungqongqo nemigangatho yelizwe laseTshayina ukuqinisekisa ukuthembeka nokuzinza kwayo. Oku kulandelayo yintshayelelo eneenkcukacha kumgangatho wesizwe womgangatho wentsimbi yentsimbi esisigxina yevalve yebhola:
1. Iimpawu zesakhiwo:
-Uphawu oluphambili lwe-valve yebhola esisigxina kukuba ibhola igxininiswe kwaye ayikwazi ukuhamba, kwaye ukutshintshwa kufezekiswa ngokuhamba kwesihlalo sevalve. Olu luyilo lwenza umsebenzi uzinzile kwaye unokwethenjelwa.
-Ukusetyenziswa kwezinto zensimbi ezibunjiweyo kwandisa ukunyanzeliswa koxinzelelo kunye nokuxhatshazwa kwe-valve, okwenza kube lula ukulungelelanisa neendawo zokusebenza ezinzima.
2. Iimathiriyeli zecandelo eliphambili:
-Amacandelo aphambili omgangatho wesizwe owenziwe ngentsimbi eqingqiweyo iivalve zebhola zentsimbi zihlala zenziwe nge-carbon steel kunye nezixhobo zensimbi ezingenasici ukuze zivumelane neemeko zokusebenza kunye neendawo ezahlukeneyo.
3. Iindawo zokufaka izicelo:
-Ngenxa yokusebenza kwayo okugqwesileyo kunye nokuthembeka, umgangatho wesizwe owenziwe ngentsimbi yentsimbi esisigxina isetyenziswa 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. Imilinganiselo yoqhagamshelwano lwangaphandle kunye nobunzima:
-Ubungakanani boxhumo lwangaphandle kunye nobunzima beevalve zebhola ezisisigxina zingahluka ngokuxhomekeka kuxinzelelo lokusebenza kunye nobubanzi. Ngokomzekelo, kwi-PN1.6MPa kunye ne-DN50 iivalve zebhola, imilinganiselo yazo yangaphandle yi-216mm kunye nobunzima bayo yi-50kg.
6. 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 eqingqiweyo yevalve yebhola idlala indima ebalulekileyo kwiinkalo ezahlukeneyo zoshishino ngenxa yesakhiwo sayo esisodwa kunye nokusebenza okuphezulu. Ukuqonda iimpawu zayo ezisisiseko kunye nokusetyenziswa kunokunceda ukusebenzisa esi sixhobo ngcono, ukuphucula ukusebenza kakuhle kwemveliso kunye nokhuseleko.
