I-GB Cast Steel Globe Valve NgeFlange Iphetha Insimbi Engagqwali
Incazelo Yokukhiqiza
● Imikhiqizo yamavalvu embulunga yonke iklanywe futhi yakhiqizwa ngokwezinga likazwelonke le-GB12235, elinesakhiwo esinengqondo, ukubekwa uphawu okuthembekile, ukusebenza okuhle kakhulu nokubukeka okuhle.
● I-valve disc kanye ne-valve seat seat sealing surface yenziwe nge-iron-based alloy surfacing noma i-stellite cobalt-based hard alloy Surfacing, enokumelana okuhle nokugqokwa, ukumelana nokushisa okuphezulu, ukumelana nokugqwala, ukumelana nokuklwejwa okuhle nempilo ende yesevisi.
● Isiqu se-valve siyacishwa futhi siyaqina futhi sine-nitrided engaphezulu, enokumelana nokugqwala okuhle nokunganyakazi.
● Amazinga ahlukahlukene e-piping flange namafomu angaphezulu okuvala i-flange angasetshenziswa ukuze kuhlangatshezwane nezidingo ezihlukahlukene zobunjiniyela kanye nezidingo zomsebenzisi.
● Isigxivizo esihlanekezelwe senziwe ngesihlalo sophawu lokuxhuma okunentambo noma ukuvela komzimba kwensimbi engagqwali ye-austenitic, enokwethenjelwa ekubekweni uphawu, futhi ukupakishwa kungashintshwa nsuku zonke ngaphandle kokumisa uhlelo ngokufanele nangokushesha ngaphandle kokuphazamisa ukusebenza kwesistimu.
● Ukukhethwa kwezinto zokusebenza kuhle, kuhambisana nezindinganiso ezifanele zasekhaya nezangaphandle, futhi ikhwalithi iyonke yezinto zokwakha iphezulu.
● Ihlangabezana nezidingo zezindinganiso ezithuthukisiwe ekhaya naphesheya, ngokubekwa uphawu okuthembekile, ukusebenza okuhle kakhulu nokubukeka okuhle.
● Ipheya yokuvala isihambile futhi inengqondo.Izindawo zokuvala zepuleti lesango kanye nesihlalo se-valve zenziwe ngama-alloys aqinile asuselwa ku-Stellite cobalt anobunzima obuhlukahlukene.Ukubekwa uphawu kunokwethenjelwa, ukuqina okuphezulu, ukumelana nokugqokwa, ukumelana nezinga lokushisa eliphezulu, ukumelana nokugqwala, anti- Ukusebenza kahle komhuzuko nokuphila isikhathi eside.
● Isiqu se-valve siyacishwa futhi siyaqina futhi sine-nitrided engaphezulu, ekwazi ukumelana nokugqwala okuhle, ukumelana nokuklwebheka kanye nokungagugi.
● Isakhiwo sesango elinwebekayo sohlobo lwe-wedge siyamukelwa, ama-diameter aphakathi nendawo amakhulu anikezwa ama-thrust bearings, amandla okushayisana mancane, futhi afakwe ibhukwana lomthelela, elingavulwa futhi livalwe kalula.
● Isikali esinogqinsi.Ugqinsi lungaphezu kuka-10% ugqinsi kunamavalvu embulunga afanayo, futhi lunamandla okumelana nokugqwala okucindezelayo.
Indawo Yesicelo
Le valve ifanele izimboni ezihlukahlukene ezifana ne-petroleum, amakhemikhali, amandla kagesi, insimbi, izimayini, ukushisa, njll.
Indawo esetshenziswayo amanzi, uwoyela, isitimu, i-acid medium namanye amapayipi ngaphansi kwezimo zokusebenza ezehlukene.
