Indlela yokuguqula iValve Pressure PSI, BAR kunye neMPA?

Ukuguqulwa kwe-PSI kunye ne-MPA, i-PSI yiyunithi yoxinzelelo, ichazwa njenge-intshi yaseBritani / i-intshi yesikwere, i-145PSI = 1MPa, kunye ne-PSI yesiNgesi ibizwa ngokuba yi-Pounds per square in.Ungabala zonke iiyunithi ezineeyunithi zoluntu:1bar≈14.5PSI, 1PSI = 6.895kpa = 0.06895barIYurophu kunye neMelika kunye namanye amazwe asetyenziselwa ukusebenzisa i-PSI njengeyunithi.

E-China, ngokuqhelekileyo sichaza uxinzelelo lwegesi kwi "kg" (endaweni ye "pound").Iyunithi yomzimba yi “KG/CM^2″, kwaye uxinzelelo lwekhilogram enye ngamandla ekhilogram enye kwisikwere sesentimitha.

Iiyunithi ezisetyenziswa phesheya zi "PSI", kwaye iyunithi ethile yi "LB/In2", eyi "pound/square inch".Le yunithi ifana neleyibhile yobushushu (F).

Ukongeza, kukho i-PA (i-Pascal, enye i-Newton ikwimitha yesikwere enye), i-KPA, i-MPA, i-BAR, ikholomu yamanzi e-millimeter, i-millimeter mercury kunye nezinye iiyunithi zoxinzelelo.

1 Ibha (BAR) = 0.1 MPa (MPA) = 100 Knaka (KPA) = 1.0197 kg/square centimeter

1 Uxinzelelo oluqhelekileyo lwe-atmospheric (ATM) = 0.101325 MPa (MPA) = 1.0333 Ibha (BAR)

Ngenxa yokuba umahluko weyunithi umncinci kakhulu, unokukhumbula oku:

I-1 Ibha (BAR) = 1 Uxinzelelo oluqhelekileyo lwe-atmospheric (ATM) = 1 kg/square centimeter = 100 kilo (KPA) = 0.1 MPa (MPA)

Uguqulo lwePSI luhamba ngolu hlobo lulandelayo:

1 Uxinzelelo oluqhelekileyo lwe-atmospheric (ATM) = 14.696 pound / intshi 2 (PSI)

Ubudlelwane botshintsho loxinzelelo:

Uxinzelelo lwe-1 Bar (BAR) = 10^ 5 Pa (PA) 1 Dadin / cm 2 (dyn / cm2) = 0.1 Pa (PA)

1 Terr = 133.322 Pa (PA) 1 mm Hg (mmHg) = 133.322 Pa (PA)

Ikholamu yamanzi eyi-1 mm (mmh2O) = 9.80665 Pa (PA)

1 Ubunjineli boxinzelelo lwe-atmospheri = 98.0665 kite (KPA)

1 Knipa (KPA) = 0.145 pounds/inch 2 (PSI) = 0.0102 kg/cm 2 (kgf/cm2) = 0.0098 uxinzelelo lwe-atmospheric (ATM)

I-1 pound force/intshi 2 (PSI) = 6.895 kenta (KPA) = 0.0703 kg/cm 2 (kg/cm2) = 0.0689 Ibha (ibha) = 0.068 uxinzelelo lwe-atmospheric (ATM)

1 Uxinzelelo lwe-atmospheric ngokomzimba (ATM) = 101.325 Kenpa (KPA) = 14.696 iipounds / intshi 2 (PSI) = 1.0333 Ibha (BAR)

Kukho iindidi ezimbini zeiivalve: enye yinkqubo "yoxinzelelo lwegama" emelwe yiJamani (kubandakanywa nelizwe lam) kwiqondo lokushisa eliqhelekileyo (e-China yi-100 degrees kunye neJamani yi-120 degrees).Enye "inkqubo yoxinzelelo lobushushu" emelwe yi-US emelwe kwiqondo lokushisa elithile kwiqondo elithile.

Phakathi kwenkqubo yokushisa kunye noxinzelelo e-United States, ngaphandle kwe-150LB esekelwe kwii-degrees ze-260, amanye amanqanaba kuwo onke amanqanaba asekelwe kwi-454 degrees.

I-250 -pound (150PSI = 1MPa) No. 25 i-valve yensimbi ye-carbon yayiyi-degrees ze-260, kwaye uxinzelelo oluvumelekileyo lwaluyi-1MPa, kwaye uxinzelelo lokusetyenziswa kwiqondo lokushisa lalilikhulu kakhulu kune-1MPa, malunga ne-2.0MPa.

Ngoko ke, ngokuqhelekileyo, inqanaba loxinzelelo lwegama elihambelana nomgangatho we-US 150LB yi-2.0MPa, kunye nenqanaba loxinzelelo oluqhelekileyo oluhambelana ne-300LB yi-5.0MPa njalo njalo.

Ngoko ke, awukwazi ukutshintsha iqondo loxinzelelo kunye neqondo lokushisa ngokwendlela yokuguqulwa koxinzelelo.
