Izinzuzo zokwelashwa kwe-cryogenic yama-valve kanye nesimo se-quo yezicelo zezimboni
Ukushisa okuphansi kobuchwepheshe bokucubungula i-cryogenic bungathuthukisa kakhulu impilo yesevisi yezinto: insimbi enesivinini esikhulu, insimbi yamathuluzi, insimbi yokufa, i-electrode yethusi, izinto eziyimpuphu, i-alloy eqinile, i-ceramic, njll. Izibonelo zokusetshenziswa kokwelashwa kwe-cryogenic ukwandisa isikhathi impilo yesevisi yezingxenye zezinkampani ezithile zaseMelika kanye namanye amayunithi aseShayina akhonjisiwe kuThebula 2 kanye neThebula 3, ngokulandelana. Ithebula lesi-4 libonisa i-coefficient elinganayo yokuguqulwa kokumelana nokugqokwa kwezinye izinto ezisetshenziswa kakhulu zokufa ngemva kokwelashwa kwe-cryogenic. Ingathuthukisa ukumelana nokugqoka; Thuthukisa amandla nokuqina; Thuthukisa ukumelana nokugqwala, ukumelana nokugqoka; Thuthukisa ukumelana nomthelela; Amandla okukhathala...

Izinzuzo kanye nokusetshenziswa kwezimboni zokwelashwa kwe-cryogenic
3.1 Izinzuzo eziyinhloko zokwelashwa kwe-cryogenic
Ingathuthukisa ukumelana nokugqoka; Thuthukisa amandla nokuqina; Thuthukisa ukumelana nokugqwala, ukumelana nokugqoka; Thuthukisa ukumelana nomthelela; Thuthukisa amandla okukhathala; Ngemuva kokwelashwa kwe-cryogenic, kungaqinisekisa ukuthi izinto eziphathwayo zihlala zinezakhiwo ezithuthukisiwe zemishini; Ayibangeli ukuwohloka kosayizi womumo; Ingasetshenziswa kumsebenzi omusha/osetshenzisiwe; Ingaqeda ukucindezeleka kwangaphakathi; Thuthukisa ukuzinza kwempahla; Izindleko zokucubungula ziphansi, ngoba ukwelula impilo yamathuluzi kunganciphisa isikhathi sokushintsha kwamathuluzi nokugaya, ukuze kongiwe izindleko zokukhiqiza; Ingakwazi ukufeza imiphumela efanayo njengezinye izindlela zokwelapha ezingaphezulu (ezifana ne-Chin plating, i-chrome, i-Teflon); Izakhiwo zamangqamuzana eziqinile zingakhiqizwa, zinciphise ukungqubuzana, ukushisa nokuguga ezindaweni ezinkulu zokuthintana.

3.3 Izicelo eziyinhloko zezimboni zokwelashwa kwe-cryogenic
3.3.1 Nweba impilo yesevisi yezingxenye namathuluzi futhi uthuthukise ukumelana nokuguga
Ukushisa okuphansi kobuchwepheshe bokucubungula i-cryogenic bungathuthukisa kakhulu impilo yesevisi yezinto: insimbi enesivinini esikhulu, insimbi yamathuluzi, insimbi yokufa, i-electrode yethusi, izinto eziyimpuphu, i-alloy eqinile, i-ceramic, njll. Izibonelo zokusetshenziswa kokwelashwa kwe-cryogenic ukwandisa isikhathi impilo yesevisi yezingxenye zezinkampani ezithile zaseMelika kanye namanye amayunithi aseShayina akhonjisiwe kuThebula 2 kanye neThebula 3, ngokulandelana. Ithebula lesi-4 libonisa i-coefficient elinganayo yokuguqulwa kokumelana nokugqokwa kwezinye izinto ezisetshenziswa kakhulu zokufa ngemva kokwelashwa kwe-cryogenic. Njengoba kungabonakala kumathebula amathathu alandelayo, ukwelashwa kwe-cryogenic kukhiqiza imiphumela ehlukene ezingxenyeni namathuluzi ezinto ezihlukahlukene, futhi ukumelana nokugqoka kwezingxenye namathuluzi kuthuthukiswa kakhulu.
Ithebula 2 Izibonelo zezinkampani ezithile e-United States ezisebenzisa ukwelashwa kwe-cryogenic ukwelula impilo yesevisi yezingxenye
Ithebula 3 Izibonelo zempilo yesevisi yokwelashwa kwe-cryogenic yasekhaya ama-workpieces aphezulu
Ithebula 4 Ushintsho lwempilo yesikhunta ngemuva kokwelashwa kwe-cryogenic
Ithebula 5 Ukukhiqizwa kwensimu kanye nemiphumela yokuhlolwa kokwelashwa kwe-cryogenic
3.3.2 Ukwenza ngcono ukuzinza kwezinto
Ukuthuthukisa ukuzinza kwezinto kungenye indlela ephumelelayo yokwelashwa kwe-cryogenic ku-aluminium, ithusi, iChin kanye nezinsimbi ezingenasici ezingama-300, ikakhulukazi i-aluminium nama-alloys ayo.
3.3.3 Ukwenza ngcono izakhiwo zempahla
Ukwelashwa kwe-Cryogenic kungathuthukisa futhi kuthuthukise izakhiwo zezinto ezibonakalayo, njengamandla, ukumelana nokukhathala, ukumelana nokugqwala, njll. Ithebula lesi-5 libonisa imiphumela yenkambu etholwe ekusetshenzisweni kocwaningo lwasenyuvesi nocwaningo lwezimboni ekukhiqizeni izimboni.
Ngokuthuthuka kwemboni yesimanje, izidingo zezakhiwo ezibonakalayo ziphakeme futhi ziphakeme. Kunamathrendi amabili amakhulu ocwaningweni lwezinto zesimanje:
① Hlala uthuthukisa ubuchwepheshe obusha, izinqubo ezintsha kanye nezisetshenziswa ezintsha zokuthuthukisa izinhlobonhlobo zezinto ezintsha ezinezidingo ezikhethekile noma izakhiwo ezinhle kakhulu, njengokuqiniswa okusheshayo, ingxubevange yemishini, i-jet deposition, ukubumba umjovo nezinye izinqubo zokuthuthukisa i-microcrystalline, i-amorphous, i-quasicrystal, i-nanocrystalline. izinto zokwakha kanye nokusebenza.
② Ngezinto ezikhona zendabuko ezifana nensimbi nensimbi, i-aluminium, ithusi esebenzisa ukuhlanzwa okuhlanzekile, ukucubungula okukhulu kwe-deformation, i-cryotreatment kanye nobunye ubuchwepheshe obukhethekile bokucubungula nokucubungula, empeleni akushintshi ukwakheka kwezinto ezikhona ngesisekelo ithuthukise kakhulu ukusebenza kwayo, ukuze ithuthukise ngempumelelo ukusetshenziswa nokubuyiselwa kwezinsiza. Ngesikhathi esifanayo, izakhiwo ezibonakalayo zingathuthukiswa, futhi izindleko zingancishiswa ukuze kuncishiswe umonakalo emvelweni, okungangabazeki ukuthi inikeza indlela enhle yokuxazulula izinkinga ezikhulayo zamandla kanye nemvelo. Ngakho-ke izifundo zezinto zokwelapha i-cryogenic zizoba isiqondiso esibalulekile socwaningo sabasebenzi besayensi yezinto ezibonakalayo ekhaya nakwamanye amazwe, kodwa ukuzinza kocwaningo olukhona kokubili kunqubo yokwelapha ye-cryogenic kanye nendlela yokwenza ezinye izinto zokucwaninga zisekhona amaphutha amaningi, ngoba ezinkulu kanye nokusetshenziswa ukwelashwa cryogenic ezimbonini kwaletha izithiyo, Ngakho-ke, ukuthuthukiswa kanye nocwaningo ezinzile cryogenic inqubo inqubo kanye cryogenic ukwelashwa indlela yezinsimbi non-ayoni kuyoba okugxilwe ucwaningo kulo mkhakha.
Ngokuthuthuka kwesayensi nobuchwepheshe kanye nomnotho, ukucaciswa kwama-valve kuya ngokuya kuyanda, futhi kuye kwavela izinhlobo ezintsha nezikhethekile zamavalvu, ezedlula kude ububanzi bevalvu embozwe indlela ekhona yokuhlanganisa imodeli ye-valve i-JB/T 308 ezweni lakithi. . Indlela ehlanganisiwe yokuhlanganiswa kwemodeli yama-valve idlala indima ebalulekile ekusheshiseni ukuthuthukiswa kokubambisana kwemboni yama-valve, ithuthukise uchungechunge lwezimboni, futhi ihlale icwenga ukuhlukaniswa kwezenhlalo kwabasebenzi.
Okokuqala, indima yemodeli ye-valve
Ngokuthuthuka kwesayensi nobuchwepheshe kanye nomnotho, ukucaciswa kwamavalvu kuya ngokuya kuyanda, futhi kuvela izinhlobonhlobo zamavalvu amasha futhi akhethekile, angaphezu kwebanga levalvu elimbozwe indlela ekhona yokuhlanganisa imodeli ye-valve JB/T 308 izwe lethu. Indlela ehlanganisiwe yokuhlanganiswa kwemodeli yama-valve idlala indima ebalulekile ekusheshiseni ukuthuthukiswa kokubambisana kwemboni yama-valve, ithuthukise uchungechunge lwezimboni, futhi ihlale icwenga ukuhlukaniswa kwezenhlalo kwabasebenzi.
Ngesikhathi esifanayo, ngenxa yokuncintisana okunamandla kwemboni ye-valve, ngamunye abakhiqizi abakhulu be-valve ekhaya nakwamanye amazwe ukuze bagcinwe ku-petroleum, amakhemikhali, amandla kagesi kanye nezinye inqubo yokubhida yephrojekthi enkulu bangakwazi ukufaka izici zemikhiqizo yabo, ukuvikela. izithakazelo zabo siqu zomnotho, ngokuvamile abasebenzisi JB/T 308 indlela yokusungulwa kwemodeli valve, by sui generis valve imodeli ukusungulwa indlela.
Okubili, indlela yokulungiselela imodeli ye-valve ye-JB/T 308-2004
I-JB/T 308-2004 Indlela Yokulungiselela Imodeli Isebenza ekulungiseni imodeli yamavalvu esango, ama-globe valves, ama-throttle valves, ama-butterfly valves, ama-ball valves, ama-diaphragm valves, amapulaki ama-valve, ama-valve okuhlola, ama-valve okuphepha, ama-valve okunciphisa umfutho, izicupho zesitimu. , ama-valve e-blowdown, ama-plunger valves neminye imikhiqizo kuma-valve ajwayelekile.
Imodeli ye-valve eshiwo yi-JB/T 308-2004 yakhiwe ngalezi zakhi ezilandelayo: uhlobo lwe-valve, imodi yokushayela, ifomu lokuxhuma, ifomu lesakhiwo, impahla engaphezulu yokuvala noma uhlobo lwempahla yomugqa, ikhodi yokucindezela noma ikhodi yokucindezela yokusebenza ekushiseni okusebenzayo, umzimba we-valve. impahla kanye nezinye izingxenye eziyisikhombisa.
Ikhodi yohlobo lwevalvu:
Ikhodi yohlobo lwe-valve iqukethe ikhodi ekhethekile kanye nekhodi eyisisekelo.
Igama lekhodi eyisisekelo:
IKHODI YOHLOBO LWEVALIYI IYOVEZWA NGEZINCWADI ZASE-PINYIN ZaseShayina NJENGETHEBULALI NGALINYE 2.1 NGEZANSI.
