Khatello ea lebitso (PN) le Class American standard pound (Lb) ka bobeli ke lipontšo tsa khatello.Phapang ke hore khatello eo ba e emelang e lumellana le mocheso o fapaneng oa litšupiso.Sistimi ea Europe ea PN e bua ka khatello e ts'oanang ho 120 ℃, ha maemo a Class American a bua ka khatello e tšoanang ho 425.5 ℃.
Ka hona, phapanyetsanong ea boenjiniere, phetoho ea khatello e ke ke ea etsoa feela.Ka mohlala, phetoho ea khatello ea CLAss300 # e lokela ho ba 2.1MPa, empa haeba mocheso oa tšebeliso o nkoa, khatello e lumellanang e tla phahama, e lekanang le 5.0MPa ho ea ka mocheso le teko ea khatello ea thepa.
Ho na le mefuta e 'meli ea mekhoa ea li-valve: e' ngoe ke "khatello ea lebitso" e emetsoeng ke Jeremane (ho kenyeletsoa Chaena) 'me e itšetlehile ka khatello e lumelletsoeng ea ho sebetsa mocheso o tloaelehileng (100 ° C Chaena le 120 ° C Jeremane).E 'ngoe ke "sistimi ea khatello ea mocheso" e emeloang ke United States le khatello e lumelletsoeng ea ho sebetsa mochesong o itseng.
Tsamaisong ea mocheso le khatello ea United States, ntle le 150Lb, e thehiloeng ho 260 ° C, maemo a mang a thehiloe ho 454 ° C. Khatello e amohelehang ea No. 25 carbon steel valve ea 150lb (150PSI = 1MPa) ho 260. ℃ ke 1MPa, 'me khatello e lumelletsoeng mochesong o tloaelehileng e kholo haholo ho feta 1MPa, e ka bang 2.0MPa.
Ka hona, ka kakaretso, sehlopha sa khatello ea lebitso se lumellanang le maemo a Amerika a 150Lb ke 2.0MPa, 'me sehlopha sa khatello ea lebitso se lumellanang le 300Lb ke 5.0MPa, joalo-joalo. foromo ea phetoho.
