Tekanyetso ea API 594 ke eng

API 594, e thehiloeng ke American Petroleum Institute (API), ke tekanyetso e hlakileng ea indasteri e bitsoang "Check Valve: Flanged, Lug, Wafer, le Butt-welding Types." Tlhaloso ena ea bohlokoa e laola moralo, khetho ea thepa, litekanyo tsa sebopeho, mamello ea khatello le mocheso, le mekhoa ea tlhahlobo/tlhahlobo bakeng sa li-valve tsa tlhahlobo ea indasteri.

Bongata le Ts'ebeliso ea API 594

API 594 e sebetsa ho li-valve tsa tlhahlobo tsa Mofuta oa A (tse khutšoane lifahleho li talimane) le Mofuta oa B (tse telele lifahleho li talimane). E akaretsa ka botlalo meralo e fapaneng ea meaho, ho kenyeletsoa:

• Li-valve tsa ho hlahloba ho Swing
• Li-valve tsa ho hlahloba lifti
• Valve ea Tlhahlobo ea Lipoleiti tse peli /Valve ea ho hlahloba Wafers
• Li-valve tsa ho hlahloba serurubele
  Tekanyetso ena e sebetsa bakeng sa boholo ba li-valve ho tloha ho DN 150 (NPS 6) ho isa ho DN 400 (NPS 16). E laola li-valve tse hahiloeng ka thepa e kang tšepe e putsoa, ​​​​tšepe e ductile, tšepe ea khabone, tšepe e sa hloekang le li-alloy tse ling.

Litlhoko tsa Moralo le Lisebelisoa tsa API 594

• Ho Latela Moralo: Moralo oa valve o tlameha ho latela ka tieo litlhaloso tsa API 594.
