DN5080 Gas Pipeline Motor Floating Ball Valve
Tlhophiso Sebaka
The floating-ball valve e ka kenngoa phapeng ea khase
Melemo ea Sehlahisoa
Tšobotsi le melemo ea valve ea peipi ea peipi ea khase
1. Khatello ea ho sebetsa e kholo, 'me valve e ka buloa le ho koaloa ka mokhoa o tsitsitseng sebakeng sa ho sebetsa sa 0.4MPa;
2. Nako ea ho bula le ho koala valve e khutšoanyane, 'me nako ea ho bula le ho koala ea valve e ka tlaase ho kapa e lekana le 50s tlas'a moeli o sebetsang oa 7.2V;
3. Ha ho na tahlehelo ea khatello, 'me moralo oa mohaho oa tahlehelo ea khatello ea zero o nang le bophara ba valve o lekanang le bophara ba pipe o amoheloa;
4. Ts'ebetso ea ho koala ha valve ea ho koala e ntle, 'me tiiso e entsoe ka rabara ea nitrile e nang le mocheso o phahameng oa mocheso (60 ℃) le mocheso o tlase (-25 ℃).
5. Ka phetoho ea moeli, e ka lemoha ka nepo boemo ba boemo ba valve ea ho fetola;
6. The on-off valve e tsamaea hantle, ntle le ho thothomela le ka lerata le tlaase;
7. Lebokose la motlakase le li-gear li tiisitsoe ka ho feletseng, 'me boemo ba tšireletso ke ≥IP65, bo thibelang ka ho feletseng mokhoa oa phetisetso ho kena,' me o na le ts'ebetso e ntle ea ho phatloha;
8. 'Mele oa valve o entsoe ka aluminium, e khonang ho mamella khatello ea 1.6MPa, ho hanela ho tsosoa le ho thothomela, le ho ikamahanya le maemo a thata;
9. Bokaholimo ba 'mele oa valve ke anodized, e ntle ebile e hloekile ebile e na le ts'ebetso e ntle ea anti-corrosion;
Taelo Bakeng sa ho Sebelisa
1. Mohala o mofubelu le mohala o motšo ke lithapo tsa matla, mohala o motšo o kopantsoe le electrode e ntle, 'me mohala o mofubelu o kopantsoe le electrode e fosahetseng ho bula valve;
2. Mehala ea tlhahiso ea pontšo ea boemo ba boikhethelo: Methapo e 2 e tšoeu ke melapo e bulehileng ea li-valve, e khutšoanyane ha valve e le teng; Methapo e 2 e putsoa ke mela e koaletsoeng ea li-valve, e khutsufalitsoeng ha valve e le teng; (Ka mor'a hore valve e buloe kapa e koetsoe, hangata motlakase o atolosoa bakeng sa 5s ho netefatsa botsitso ba lets'oao le boemong)
3. Lebokose la deceleration la valve le ka fetoloa likhato tsa 180 ka kakaretso ho ea ka boiketlo ba moreki ho kenya lebokose la taolo, 'me valve e ka sebelisoa ka tloaelo ka mor'a ho potoloha;
4. Sebelisa liboutu tse tloaelehileng tsa flange ho hokela li-valve, liphaephe le li-flowmeters. Pele ho kenngoa, sefahleho sa ho qetela sa flange se lokela ho hloekisoa ka hloko ho thibela slag ea tšepe, mafome, lerōle le lintho tse ling tse bohale holim'a metsi ho tloha ho senya gasket le ho baka ho tsoa;
5. Belofo e lokela ho kenngoa phapeng kapa phallong e nang le valve e koetsoeng. E thibetsoe ka ho feletseng ho e sebelisa boemong ba khatello e feteletseng kapa ho lutla ha khase le ho lemoha ho lutla ka mollo o bulehileng;
6. Ponahalo ea sehlahisoa sena e fanoe ka letlapa la mabitso.
