DIN ANSI UPVC CPVC PPH PVDF Wafer Check Manufacture ea Valve
Lihlahisoa tsa Lihlahisoa
1) Bolelele bo bokhutšoane ba sefahleho le sefahleho le ho kenya habonolo.
2) Ho hanyetsa kutu e phahameng, e bobebe ebile e theko e boima.
3) UPVC, CPVC wafer check valve e bulehile ka ho feletseng angle e ka bang 40 °
4) Ka lebaka la bophara bo bonyenyane ba ka hare ba li-flange tsa PPH, ho fumana sebaka se seholoanyane sa ho bula, hoa hlokahala ho chamfer flange kapa ho eketsa poleiti ea ho hokahanya pakeng tsa flange le valve.
Molemo oa li-valve tsa ho hlahloba liphaephe ke ofe?
Wafer check valve e na le bolelele ba sebopeho sa li-valve tse khutšoane, boholo bo nyane le boima bo bobebe. ho koala valve ka potlako, khatello ea hamore e tlaase ea metsi, tsela e phallang e boreleli, ho hanyetsa metsi a tlaase. phaephe e tšekaletseng kapa phaephe e emeng e ka sebelisoa. Ho bonolo ho kenya, ketso e hlokolosi, ts'ebetso e ntle ea ho tiisa, ho otla ha valve e khutšoanyane, phello e nyenyane ea valve, sebopeho se bonolo, sebopeho se setle, bophelo bo bolelele ba tšebeletso, ho tšepahala ho phahameng. E thibela phallo e bohareng ea backflow / reverse, taolo ea othomathike ea ho bula le ho koala joalo-joalo.
Wafer check valve e sebelisoa haholo-holo ho petrochemical, tšepe le metallurgy ea tšepe, matla a motlakase le lisebelisoa tse ling tsa indasteri, litoropo le libaka tse phahameng tsa metsi le marang-rang a drainage. Hobane bolelele ba sebopeho sa valve ea ho hlahloba khokahanyo e khuts'oane ho feta valve ea tlhahlobo ea khokahano ea flange ea setso. Ke eona e loketseng ka ho fetisisa bakeng sa libaka tse nang le moeli oa sebaka sa ho kenya.
Ke eng eo u lokelang ho e ela hloko ha u kenya valve ea ho hlahloba liphaephe?
1. Ha ho lumelloe ho kenya valve ho sebopeho sa pompo ea flange, 'me ho kgothaletswa ho kenya valve bonyane makhetlo a 10 bolelele ba bophara ba lebitso (DN) 2 limithara ka ntle ho sebaka sa botsitso.
2. Ha u kenya valve, ho kgothaletswa ho sebelisa gasket e bataletseng ho fumana hore na ho tiisa ho tiisa eng.
3. Liphaephe tse nang le marako a marako a fetang 10 bar ha lia lumelloa. 4.
4. E loketse ho kenngoa ka holimo kapa ka holimo, ho kenngoa ka holimo ho lumella feela tataiso ea mokelikeli ho ea holimo.
5. Kenya valve pakeng tsa flanges (axis alignment) 'me u kenye torque e khothalletsoang ho tiisa li-flange ka bobeli.
