Cabbirka caadiga ah ee ANSI-Standard check valves

Thehubi waalkanashqadeeyay, la soo saaray, la soo saaray oo la tijaabiyay si waafaqsan heerka Maraykanku waxa loo yaqaan heerka Ameerikahubi waalka, haddaba waa maxay cabbirka caadiga ah ee halbeegga Ameerikahubi waalka? Waa maxay faraqa u dhexeeya isaga iyo valve hubinta heerka qaranka? Waqtigan xaadirka ah, cabbirka caadiga ah ee halbeegga Ameerikahubi valvesaad bay caan u tahay in loo qaabeeyo oo loo soo saaro si waafaqsan heerarka API iyo ASME, iyo qaar badan oo ka mid ah halbeegyada valve ee Maraykanka ayaa dhab ahaantii ku badan adduunka. Cabirka caadiga ah ee valves hubinta Heerka Ameerika waa sida soo socota: Heerarka naqshadeynta: API 6D, ASME B16.34, API 594, BS 1868, GB/T 12235, GB/T 12236, JB/T 8937 Dhererka qaabdhismeedka: ASME B16.10 , API 6D, GB/T 12221 Heerarka isku xirka: ASME B16.5, ASME B16.47, ASME B16.25, GB/T 9113, JB/T 79, HG/ T 20592 Tijaabada cadaadiska: API 598, API 6D, GB/T 13927, GB/T 26480 Cadaadiska iyo qiimeynta heerkulka: ASME B16. 34, GB/T 12224 Isticmaalka alwaaxyada globe ee Maraykanka ee gudaha deegaanka cadaadis-sare Farqiga ugu weyn ee u dhexeeya heerka Americanhubi valvesiyo heerka qarankahubi valveswaa sida soo socota: 1. Halbeegga dhexroorka magacu waa kala duwan yahay; 2. Calamada baalku way ka duwan tahay; 3. Dhererka qaabdhismeedku wuu ka duwan yahay; 4. Shuruudaha kormeerku way kala duwan yihiin.
