Mokhoa oa ho khetha valve ea lefats'e - TWS Valve

Li-valve tsa globe li sebelisoa haholo ebile li na le mefuta e mengata. Mefuta e ka sehloohong ke li-valve tsa li-globe tsa bellows, li-valve tsa globe tsa flange, li-valve tsa globe tse ka hare, li-valve tsa globe tsa tšepe e sa hloekang, li-valve tsa globe tsa DC, li-valve tsa globe tsa nale, li-valve tsa sebopeho sa Y, li-angle globe valves, joalo-joalo. , belofo ea tšepe ea tšepe e entsoeng ka tšepe, valve ea tšepe e entsoeng ka tšepe; mokhoa oa ho khetha mofuta ke oa bohlokoa haholo, o hloka ho khethoa ho ea ka litšobotsi tsa bohareng, mocheso, khatello le maemo a sebetsang. Melao e khethehileng ea khetho ke e latelang:

1. Valve ea globe ea pneumatic e lokela ho khethoa pompong kapa sesebelisoa sa mocheso o phahameng le bohareng ba khatello e phahameng. Tse kang mocheso o phahameng le liphaephe tse nang le khatello e phahameng ka har'a limela tsa matla a mocheso le mekhoa ea petrochemical;

2. Valofo ea globe ea phallo e tobileng e lokela ho sebelisoa pompong moo litlhoko tsa ho hanyetsa convection li seng thata;

3. Sephahla sa nale, valve ea lisebelisoa, sampling valve, valve gauge gauge, joalo-joalo e ka sebelisoa bakeng sa valve e nyenyane ea pneumatic globe;

4. Ho na le phetoho ea phallo kapa khatello ea khatello, empa litlhoko tsa ho nepahala ha phetoho ha li phahame, 'me bophara ba pipeline bo batla bo le nyane. Ka mohlala, ka pipeline e nang le bophara ba lebitso la ≤50mm, ho molemo ho sebelisa valve ea ho emisa pneumatic le valve ea ho laola motlakase;

5. Bakeng sa mokhoa o bonolo oa ho tiisa crystallization, khetha valve ea ho thibela mocheso e thibelang mocheso;

6. Bakeng sa maemo a khatello e phahameng haholo, ho lokela ho khethoa li-valve tsa globe tse entsoeng;

7. Manyolo a manyenyane le manyolo a maholo ka tlhahiso ea liindasteri ea maiketsetso a lokela ho khetha khatello e phahameng ea angle globe valve kapa khatello e phahameng ea angle throttle valve e nang le khatello ea lebitso la PN160 khatello ea lebitso 16MPa kapa PN320 khatello ea lebitso 32MPa;

8. Sebakeng sa desiliconization workshop le liphaephe tse atisang ho pheha ka mokhoa oa alumina Bayer, ho bonolo ho khetha valve ea globe e phallang ka ho toba kapa valve e phallang ka ho toba e nang le 'mele o arohaneng oa valve, setulo sa valve se ntšitsoeng le samente. carbide sealing para;

9. Mererong ea phepelo ea metsi le ea ho futhumatsa mohahong oa litoropo, sebaka se senyenyane se senyenyane, 'me ho ka khethoa valve ea pneumatic shut-off, valve balance kapa plunger valve, ka mohlala, tsela ea lebitso e ka tlaase ho 150mm.

10. Ho molemo ho khetha bellows globe valve e tsoang kantle ho naha bakeng sa high mocheso mouoane le chefo le kotsi mecha ea litaba.

11. Bakeng sa valve ea globe ea acid-base, khetha valve ea globe ea tšepe e sa hloekang kapa e nang le fluorine-lined globe valve.
