3.3 Izicelo eziphambili zoshishino zonyango lwe-cryogenic
3.3.1 Yandisa ubomi benkonzo yamalungu kunye nezixhobo kunye nokuphucula ukuxhathisa ukunxiba
Ubushushu obuphantsi beteknoloji ye-cryogenic processing inokuphucula kakhulu ubomi benkonzo yezinto ezi: i-high-speed steel, isixhobo sentsimbi, intsimbi yokufa, i-electrode yobhedu, izinto zomgubo, i-alloy eqinile, i-ceramic, njl. ubomi benkonzo yeenxalenye zezinye iinkampani zaseMelika kunye nezinye iiyunithi zaseTshayina ziboniswe kwiThebhile 2 kunye neTheyibhile 3, ngokulandelelanayo. Itheyibhile ye-4 ibonisa i-coefficient elinganayo yokuguqulwa kokumelana nokunxiba kwezinye izinto ezisetyenziswa ngokuqhelekileyo zokufa emva konyango lwe-cryogenic. Njengoko kunokubonwa kwiitheyibhile ezintathu ezilandelayo, unyango lwe-cryogenic luvelisa iziphumo ezahlukeneyo kwiindawo kunye nezixhobo zezixhobo ezahlukeneyo, kunye nokuxhatshazwa kwezixhobo kunye nezixhobo ziphuculwe kakhulu.
Uluhlu lwesi-2 Imizekelo yeenkampani ezithile e-United States ezisebenzisa unyango lwe-cryogenic ukwandisa ubomi benkonzo yamalungu
Itheyibhile 3 Imizekelo yobomi benkonzo yasekhaya cryogenic unyango workpieces eliphezulu
Itheyibhile 4 Ukutshintsha kobomi besikhunta emva konyango lwe-cryogenic
Itheyibhile 5 Ukuveliswa kwentsimi kunye neziphumo zokuvavanya unyango lwe-cryogenic
3.3.2 Ukuphucula uzinzo lwemathiriyeli
Ukuphucula ukuzinza kwezixhobo sesinye isicelo esiyimpumelelo sonyango lwe-cryogenic kwi-aluminium, ubhedu, i-Chin kunye ne-300 series steels stainless steels, ngokugqithiseleyo i-aluminium kunye ne-alloys yayo.
3.3.3 Ukuphucula iimpawu zemathiriyeli
Unyango lwe-Cryogenic lunokuphucula nokuphucula izinto eziphathekayo, njengamandla, ukuxhathisa ukukhathala, ukuxhathisa ukubola, njl.
Ngophuhliso loshishino lwanamhlanje, iimfuno zezinto eziphathekayo ziphezulu kwaye ziphezulu. Kukho iindlela ezimbini eziphambili kuphando lwezixhobo zangoku:
① Hlala uphuhlisa itekhnoloji entsha, iinkqubo ezintsha kunye nezixhobo ezitsha zokuphuhlisa iintlobo ngeentlobo zemathiriyeli eneemfuno ezizodwa okanye iipropathi ezigqwesileyo, ezinje ngokuqiniswa ngokukhawuleza, i-alloying yoomatshini, ukubekwa kwejethi, ukubumba inaliti kunye nezinye iinkqubo zokuphuhlisa i-microcrystalline, amorphous, quasicrystal, nanocrystalline. izinto zokwakha kunye nokusebenza.
② Kwizinto zemveli ezikhoyo ezifana nentsimbi kunye nentsimbi, i-aluminium, ubhedu kusetyenziswa ukuhlanjululwa kwe-ultra-pure, ukulungiswa okukhulu kwe-deformation, i-cryotreatment kunye nezinye izinto ezikhethekileyo kunye neteknoloji yokucubungula, kwisiseko ayitshintshi ukubunjwa kwezinto ezikhoyo ngesiseko iphucule kakhulu ukusebenza kwayo, ukuze iphucule ngokusebenzayo ukusetyenziswa nokubuyiselwa kwezibonelelo. Ngelo xesha, izinto eziphathekayo zinokuphuculwa, kwaye iindleko zingancitshiswa ukunciphisa umonakalo wokusingqongileyo, ngokungathandabuzekiyo ubonelela ngendlela efanelekileyo yokusombulula iingxaki ezikhulayo zamandla kunye nokusingqongileyo. Ngoko ke izifundo izinto zonyango cryogenic iya kuba ulwalathiso uphando ebalulekileyo yabasebenzi zenzululwazi eziphathekayo ekhaya nakwamanye amazwe, kodwa uzinzo uphando ekhoyo zombini kwinkqubo cryogenic unyango kunye nendlela yokusebenza kwezinye izinto uphando kusekho iintsilelo ezininzi, kuba ezinkulu kunye nokusetyenziswa unyango cryogenic kwishishini kwazisa imiqobo, Ngoko ke, uphuhliso kunye nophando lwenkqubo cryogenic oluzinzileyo kunye nenkqubo cryogenic unyango lwesinyithi non-ayoni iya kuba kugxininiso lophando kule nkalo.
Ngophuhliso lwenzululwazi kunye nobuchwepheshe kunye noqoqosho, ukucaciswa kwevalve kuyanda ngakumbi, kwaye kuye kwavela iintlobo ezintsha nezikhethekileyo zevalve, ezingaphaya koluhlu lwevalvu egqunywe yindlela ekhoyo yokuqulunqa ivalve ye-JB/T 308 kwilizwe lethu. . Indlela edityanisiweyo yokuhlanganiswa kwemodeli yevalvu idlala indima ebalulekileyo ekukhawuleziseni uphuhliso lwentsebenziswano yoshishino lwevalvu, ngakumbi ukuphucula ikhonkco lemizi-mveliso, kunye nokucokisa rhoqo ukwahlulwa kwezentlalo zabasebenzi.
Okokuqala, indima yemodeli yevalve
Ngophuhliso lwenzululwazi kunye nobuchwepheshe kunye noqoqosho, iinkcukacha zevalvu ziya zisanda, kwaye iintlobo ngeentlobo zeevalvu ezintsha nezikhethekileyo ziyavela, ezingaphaya koluhlu lwevalvu egqunywe yindlela ekhoyo yokuhlanganiswa kwevalvu ye-JB/T 308 ilizwe lethu. Indlela edityanisiweyo yokuhlanganiswa kwemodeli yevalvu idlala indima ebalulekileyo ekukhawuleziseni uphuhliso lwentsebenziswano yoshishino lwevalvu, ngakumbi ukuphucula ikhonkco lemizi-mveliso, kunye nokucokisa rhoqo ukwahlulwa kwezentlalo zabasebenzi.
Kwangaxeshanye, ngenxa yoshishino lwevalvu luyanda ukhuphiswano oluqatha, abavelisi bevalufa nganye enkulu ekhaya nakwamanye amazwe ukuze bagcinwe kwipetroleum, imichiza, amandla ombane kunye nenye inkqubo enkulu yebhidi yeprojekthi inokubandakanya ngakumbi iimpawu zeemveliso zabo, ukukhusela. imidla yabo yezoqoqosho, kaninzi abasebenzisi JB/T 308 indlela yokusekwa kwevalvu emanyeneyo, nge-sui generis valve model indlela yokusekwa.
Ezimbini, i-JB/T 308-2004 imodeli yokulungiselela indlela yevalvu
I-JB/T 308-2004 Indlela yokuLungiselela iModeli yeValve iyasebenza kulungiselelo lwemodeli yeevalvu zesango, iivalvu zeglowubhu, iivalve ze-throttle, iivalve zebhabhathane, iivalve zebhola, i-diaphragm valves, iplagi valves, itshekhi ivalvu, iivalvu zokhuseleko, iivalve zokunciphisa uxinzelelo, i-steam traps. , iivalvu zokuvuthela, iivalve zeplunger kunye nezinye iimveliso kwiivalvu jikelele.
Imodeli yevalve echazwe yi-JB / T 308-2004 iqulunqwe zezi zinto zilandelayo: uhlobo lwevalve, imowudi yokuqhuba, ifom yokudibanisa, ifom yesakhiwo, ukutywinwa kwezinto ezingaphezulu okanye uhlobo lwe-lining material, ikhowudi yoxinzelelo okanye ikhowudi yokusebenza kwiqondo lokushisa, umzimba wevalve. impahla kunye nezinye iinxalenye ezisixhenxe.
Ikhowudi yodidi lwevalvu:
Ikhowudi yohlobo lwevalve iqukethe ikhowudi ekhethekileyo kunye nekhowudi esisiseko.
Igama lekhowudi esisiseko:
IKHOWUDI YOHLOBO LWEVALIVI IYA KUCACISWA NGOONObumba baseTshayina be-PINYIN NJENGETHEYIBHILE KANYE 2.1 NGEZANSI.
