3. Yenza "izindlu ezintathu" zeValve
Ngokungqinelana nomoya weentlanganiso ezimbini zeKaifeng kunye nezimvo zeZiko eliShindisiweyo loMphathiswa Wez lomatshini, iZiko loPhando oluPhakamileyo "liphinde lenze umsebenzi we-valves enkulu" yokuphumelela kwendawo yokuphumelela kwimveliso eyahlukeneyo kwishishini. Umsebenzi "othathu" ngumsebenzi obalulekileyo wobugcisa, ongumlinganiso osebenzayo wokukhawulezisa ukutshintsha kobuchwephesha bamashishini kunye nokuphucula inqanaba le-valve. I-valve "yokusebenza" isebenza ngokokusebenza "ezine ezilungileyo" (kulula ukuzakha, kulula ukulungisa kunye "nokudibana okuhle) kunye" neparamitha ezine "(iinxalenye zomsebenzi) imigaqo, iinxalenye zomsebenzi, Umxholo ophambili womsebenzi unemiba emithathu, enye kukwenza lula iintlobo ezixineneyo; enye kukuqulunqa kwaye ihlaziye i-batch yemigangatho yobugcisa; Elesithathu kukukhetha kwaye ligqibezela iimveliso.
4. Uphando lobugcisa lukhuthaze ukuphuculwa kophando lwezenzululwazi
. Ngo-1971, abaphandi benzululwazi babuyela kwiqela elinye, kwaye i-vaboratoring yevalup ye-valve yanda kubantu abangaphezu kwama-30, kwaye yathunyelwa inkonzo yokulungiselela uphando lobugcisa. Kwakhiwe ilabhoratri elula, kufakwe isixhobo sovavanyo lokuhamba nokuhamba kweenyawo, kunye noxinzelelo oluthile, ukupakisha kunye nolunye oomatshini bovavanyo lwenziwe kwaye lwenziwa uphando kwi-valve yokupakisha.
. Phakathi kwazo, kukho izinto ezi-8 zokulungiswa kwe-thermal, izinto ezili-16 zokupakisha, izinto ezi-6 zokupakisha, i-1 yento yesixhobo sombane, kunye ne-6 yovavanyo. Emva kwexesha, kwi-Harbin Welling IZiko loPhando, iZiko loPhando lweMfuno Matshini, abasebenzi abakhethekileyo baqeshwa ukuze baqokelelene, kwaye basebenzise iiNkomfa zophando eziPhezulu ze-1986. Ngeenkqubo zophando eziphezulu ze-1986 zenziwe ngophando lobugcisa Umsebenzi, oye wakhuthaza ukuphuculwa kophando lwezenzululwazi kumzi-mveliso we-veli. Iziphumo zabo eziphambili zezi zilandelayo:
1) Takisha kumhlaba wokutywina. Uphando lophando lokutywina lujolise ekusombululeni ingxaki yokuvuza kwangaphakathi kweivalve. Ngelo xesha, izinto zokutywina komhlaba ikakhulu zazingama-20ccrcc13 ne-12cct18n18ni9, ezazihluthwa ziingxaki eziphantsi, iingxaki ezimfutshane zangaphakathi ezikwiimveliso zevalve, kunye nobomi benkonzo omfutshane. IZiko loPhando lweShenyang Valve, i-Harbin Welding Institute kunye ne-Harban Boiler Umzi-mveliso wasenzela iqela elidibeneyo lophando. Emva kweminyaka emi-2 yokusebenza nzima, uhlobo olutsha lwe-chrome-manganese itywina ngezinto zokwenza indawo (i-20cc122) yaphuhliswa. Umxholo unenkqubo elungileyo yokusebenza. Ukuxhathisa okuhle, ubomi benkonzo ende, kwaye akukho Cokelium kunye neChromium engaphantsi, emva kovavanyo lobuchwephesha, lubaluleke kakhulu ekuqinisekiseni.
2) Ukuzalisa uphando. Injongo yophando lokupakisha kukusombulula ingxaki yokuvuza kwe-valve. Ngelo xesha, ukupakisha i-velic yayingafakwanga i-Asbestos ye-ASBESSOS kunye nerabha yerabha, kwaye intsebenzo yokutywina yayingalunganga, ebangela ukuvuza ivalve. Ngo-1967, iZiko loPhando oluQhelekileyo loMatshini abahleliweyo laququzelela iqela lemibhobho yokuphanda ukuba liphande ngezityalo ezithile zemichiza, iZityalo zeoyile kunye nezityalo zovavanyo ze-anti-colosion kunye neziqu zokuhamba kunye ne-verosion.
3) Uvavanyo lwentsebenzo yemveliso kunye nophando olusisiseko lwe-theoretical. Ngelixa uqhuba uphando lobugcisa,ishishini le-valveKwakhona ngenxa yokuvavanywa kwentsebenzo yemveliso kunye nophando olusisiseko lwe-theoretical, kwaye baphumelele iziphumo ezininzi.
I-5. Yenza inguqu yetekhnoloji yamashishini
Emva kweNkomfa yeKaifeng ngo-1973, ishishini liphela liphumeze inguqu yeTekhnoloji. Ezona ngxaki ziphambili zikho kwishishini le-veli ngelo xesha: okokuqala, inkqubo yayibubuyile, i-Count yayenziwe ngesandla, isixhobo esinenjongo kunye nemishini yenjongo eqhelekileyo esetyenziselwa ukubanda. Kungenxa yokuba iindidi kunye neenkcazo zomzi-mveliso ngamnye ziphindaphindwe kakhulu, kwaye inani likhulu kwilizwe liphela, kodwa emva kokusasazwa komzi-mveliso ngamnye, i-batch yemveliso incinci kakhulu, echaphazela ukungasebenzi komthamo wemveliso. Ukuphendula kwezi ngxaki zingasentla, iZiko eliShukumileyo neMphathiswa LOKUQALA LOKUQALA LOKUQALA: Lungelelanisa i-virve vallows ekhoyo, yenza ucwangciso oluhlanganisiweyo, ukwandisa ukuveliswa kobuninzi; Ukwamkelwa kwetekhnoloji yoThengiso, ukuseka imigca kwiNdawo, kunye nokusebenzisana neeNtloko eziphambili kunye nezikhala.

. Ukuphola ngokuchanekileyo kunokuqonda i-chip-encinci okanye i-chip-free chien. Ilungele isango, ukupakisha i-gland kunye ne-valve kunye ne-bonnet yeevalve ezincinci zedayam, kunye nezibonelelo zoqoqosho ezicacileyo. Ngo-1969, uShanghai Lianggong Valve Palve uqalise ukuphunyezwa kwenkqubo yokuphosa iveli kwiveli, ye-PN16.
. Njengango-1964, i-shanghai ivutha lemizi-nkqubo. Emva koko, i-shanghai ivutha lemizi-mveliso kwaye yenziwa kwaye yavelisa umgca ozenzekelayo wemveliso ye-DN500 ye-DN100 ye-DN100 yeBennet Valve kunye ne-bonnet ngo-1966.
I-6.
Ukwenzela ukuhlangabezana neemfuno zeseti ezinkulu ezigqityiweyo zezixhobo ezifana nepetroleum, ishishini lekhemikhali, ishishini lombane, ishishini le-Petrollgergy kunye ne-Verochemical kunye ne-Veroheminer kunye ne-Petrochemical kunye ne-Verochemical kunye ne-Petrolgrical Specieres, ephucule inqanaba lokulinganisa lweemveliso ze-valve.
Isishwankathelo se-03
Ukujonga emva ngo-1967-1978, ukuphuculwa kweivalve Ishishini lachaphazeleka kakhulu. Ngenxa yophuhliso olukhawulezileyo lwepetroleum, amachiza, amaqhina ombane, amashishini e-MetalArgergergergers, iivali eziphezulu neziphakathi nezexesha eliphakathi nezethutyana. Ngo-1972, umbutho wecandelo le-valve waqala ukuphinda uqalise kwaye wenze imisebenzi. Emva kweenkomfa ezimbini zeKaifeng, ziqhutywa ngamandla "umsebenzi" othathu wokuzalwa "kunye nomsebenzi wophando wobugcisa, ukumisela i-wave yenguqu yenguqu kwishishini lonke. Ngo-1975, ishishini le-valve laqala ukulungisa, kwaye imveliso yeshishini ithathe ithuba elingcono.
Ngo-1973, iKhomishini yokuCwangcisa kukaRhulumente yamkele amanyathelo okusebenza kwemveliso yokwanda kwemveliso ephezulu nephakathiivali. Emva kotyalo-mali, ishishini le-vall iqhubekisiwe utshintsho olunokubakho. Ngotshintsho lwetekhnoloji kunye nokukhuthaza, abanye betekhnoloji abaye bamkelwa, ukuze inqanaba lokuqhubekeka ukubanda kulo lonke ishishini liphuculwe kwinqanaba elithile, kwaye inqanaba lokulungiswa koomatshini liphuculwe ukuya kuthi ga kwinqanaba elithile. Emva kokukhuthaza i-Plasma Spreling yeWeling, umgangatho wemveliso weevalva eziphezulu nephakathi ziphuculwe kakhulu, kunye nengxaki "ye-" enye emfutshane neyesibini iphuculwe. Ngokuzaliswa kunye nokusebenza kweeProjekthi ezingama-32 zokuSebenza kweeProjekthi ze-32, ishishini le-van ye-china linendawo enamandla kunye nemveliso enkulu. Ukususela ngo-1970, impatho yee-valves eziphezulu nephakathi kunye nephakathi ziye zaqhubeka zikhula. Ukususela ngo-1972 ukuya ku-1975, itheko inyuke ukusuka kwi-21,2845 ye-38 500t, ngokunyuka kwe-1,216T kwiminyaka emi-4, i-valve yonyaka ithe yazinza kwinqanaba lama-70,000 kwiitoni ezingama-70,000 ukuya kwi-80,000 yeetoni. Ngeli xesha,ivalve Ishishini liphuhlise ngamandla iimveliso ezintsha, kungekuphela nje iintlobo ezahlukeneyo zeeValupe-valves ziphuhliswe kakhulu, kodwa kwane-valves ekhethekileyo yezikhululo zamandla, ishishini eliphezulu, ishishini eliphezulu kunye neeValupas zenyukhwe, kunye neeValupas zenyukhwe. Ukuba i-1960s yayilixesha lokukhula okukhulu kweeVlanga ngokubanzi, ke nge-1970s yayilixesha lophuhliso olukhulu lweevavaphu ezizodwa. Umthamo oxhasayo wasekhayaivali iye yaphuculwa kakhulu, eyayihlangabezana neemfuno zophuhliso lwamacandelo oqoqosho lwesizwe.
