Umgangatho ophezulu woShishino wePSB ujingi wokukhangela ivalvu yaseTshayina umnikezeli wefektri Umenzi
Yintoni ivalve yokukhangela ujingi yePSB?
Iivalvu zokutshekisha, iivalvu ezingabuyiyo, ziyilelwe ukuthintela ukubuya umva kokuhamba kwindlela yemibhobho.Ezi zivalo zenziwa zisebenze yimathiriyeli ehambayo kumbhobho.Uxinzelelo lolwelo oludlula kwisistim luvula ivalve, ngelixa nakuphi na ukuguqulwa kokuhamba kuya kuvala ivalve.Ukuvalwa kufezwa ngobunzima bomatshini wokutshekisha, ngoxinzelelo lwangasemva, ngentwasahlobo, okanye ngokudityaniswa kwezi ndlela.
Ivalve yokujonga ujingi yePSB,ivalve yokukhangela ujingi eyilwe kwaye yenziwe ngokuhambelana ne-ASME B16.34,uvavanyo kwaye uhlole ukuya kwi-API598,API6D.
Oko kuvuleka kufuneka kucace ukuze nantoni na idlule.I-disc idityaniswe kwihinge, ngoko ke idiski inokujiyiza ivuleke okanye ivalwe xa ulwelo lubetha idiski.Kufana nocango olusisangqa.Isalathiso sokuhamba yeyona nto ibalulekileyo xa usebenzisa ezi valves.
Xa ulwelo luhamba ngendlela oyifunayo, uxinzelelo lokuhamba lutyhala ucango luvuleke, luvumela ulwelo ukuba ludlule.Xa ulwelo luhamba ngendlela engalunganga, kwenzeka okwahlukileyo.Amandla olwelo olubuya ngevalvu lutyhala idiski kwisitulo sayo, ivale ivalve.Xa ufaka ivalve yokujonga ujingi, kubalulekile ukuba ivuleke xa ulwelo ludlula kwicala olifunayo.Ukuba ufaka enye yezi valve kwaye akukho manzi adlulayo, yindlela engafanelekanga yokujikeleza kwaye kufuneka iphinde ifakwe.Ukuba ivalve yakho yokujonga ujingi inoyilo lwenyani lomanyano, inokususwa ngokulula kumbhobho.Ezi zivalo zifumaneka ngeendlela ezininzi ezahlukeneyo.Iivalvu zentsimbi zokujonga ujingi zidla ngokubonwa kusetyenziso olunzima lwemizi-mveliso.
Iimpawu eziphambili ze-PSB swing check valve
Iimpawu eziphambili zeI-ASME Swing Check Valves:
- ● Umzimba kunye nesigqubuthelo: Precision machined castings.stem ayingeni emzimbeni.
- ● Umzimba kunye nesigqubuthelo esidityanisiweyo: i-spiral wound gasket, intsimbi engatyiwayo enegraphite okanye i-PTFE.
- ● Ukudibanisa i-Disc: I-disc engajikeleziyo ibotshelelwe ngokukhuselekileyo kwi-disc hanger nge-lock nut kunye ne-cotter pin.I-disc hanger ixhaswa kwiphini yehinge yediskhi eyomeleleyo eneempawu ezithwalayo ezibalaseleyo.Zonke iindawo zifikeleleka ukusuka phezulu ukuze zisebenze lula.
- ● Flanges:ASME B16.5,Class150-300-600-900-1500-2500
