01 Di divɛlɔpmɛnt fɔ di industri de afɛkt
Frɔm 1967 to 1978, bikɔs ɔf di big chenj dɛn we dɔn apin na di soshal ɛnvayrɔmɛnt, di divɛlɔpmɛnt fɔ di valv industri dɔn afɛkt bak bad bad wan. Di men tin dɛn we de sho se pɔsin de si am na:
1. Di valv di autput de ridyus shap, εn di kwaliti de ridyus bכku bכku wan
2. Di valv sayɛns risach sistɛm we dɔn bigin fɔ tek shep dɔn afɛkt
3. Midul prɛshɔn valv prodakt dɛn kin bi shɔt tɛm bak
4. Di prodakshɔn we dɛn nɔ bin plan fɔ mek fɔ ay ɛn midul prɛshɔn valv dɛn bigin fɔ apia
02 Tek tin dɛn fɔ mek di “valv shɔt layn” lɔng .
Di kwaliti fɔ di prɔdak dɛn we de insaydi valvindustri dɔn dכn siriכs, εn afta di fכmeshכn fכ sכt tεm hεy εn mεdiכm prεshכn valv prodakt dεm, di stet de gi big impכtant to dis. Di Hevi ɛn Jɛnɛral Biuro fɔ di Fɔs Ministri fɔ Mashin bin mek wan valv grup fɔ bi di wan we go ripɔtabl fɔ di tɛknikal transfɔmeshɔn fɔ di valv industri. Afta dip invɛstigeshɔn ɛn risach, di valv tim put di “Ripɔt bɔt di Opinion dɛn bɔt di Divɛlɔpmɛnt fɔ Prodakshɔn Mɛzhɔ fɔ Ay ɛn Midul Prɛshɔn Valv”, we dɛn sɛn to di Stet Planin Kɔmishɔn. Afta risach, dɛn disayd fɔ invɛst 52 milyɔn yuan na di valv industri fɔ du tɛknikal transfɔmeshɔn fɔ sɔlv di prɔblɛm we gɛt siriɔs shɔtat fɔ ay ɛn midul prɛshɔnvalv dɛn ɛn kwaliti de go dɔŋ kwik kwik wan.
1. Tu Kaifeng mitin
Insay Me 1972, di Fɔs Mashin Dipatmɛnt bin gɛt wan nashɔnalvalvindustri wok simposiɔm na Kaifeng Siti, Henan Prɔvins. Na 125 yunit ɛn 198 ripɔt frɔm 88 valv faktri dɛm, 8 rilevɛns sayɛns risach ɛn dizayn institiut dɛm, 13 provinsial ɛn munisipaliti mashin biro dɛm ɛn sɔm pipul dɛm we de yuz am bin atɛnd di mitin. Di mitin disayd fɔ mek di tu ɔganayzeshɔn dɛn we de na di industri ɛn di intɛlijɛns nɛtwɔk kam bak, ɛn dɛn pik Kaifeng Ay Prɛshɔn Valv Faktɔri ɛn Tieling Valv Faktɔri as di ay-prɛshɔn ɛn lɔw-prɛshɔn tim lida dɛn, ɛn na Hefei Jɛnɛral Mashin Risach Instityut ɛn Shenyang Valv Risach Instityut bin ripɔtabl fɔ di intɛlijɛns nɛtwɔk wok. Di mitin bin tɔk bak bɔt ɛn stɔdi bɔt tin dɛn we gɛt fɔ du wit “tri mɔdanizashɔn”, fɔ mek di prɔdak kwaliti bɛtɛ, fɔ mek dɛn du tɛnki risach, fɔ sheb di prɔdak, ɛn fɔ divɛlɔp di industri ɛn intɛlijɛns aktiviti dɛn. Frɔm da tɛm de, di industri ɛn intɛlijɛns wok dɛn we dɛn dɔn stɔp fɔ siks ia dɔn bigin bak. Dɛn tin ya dɔn ple big pat fɔ mek dɛn prodyuz valv ɛn fɔ rivɛns di shɔt tɛm sityueshɔn.
2. Risum industri ɔganayzeshɔn aktiviti ɛn infɔmeshɔn ɛkshɛnj
Afta di Kaifeng Kɔnfrɛns insay 1972, di industri grup dɛn bigin fɔ du dɛn wok bak. Da tɛm de, na 72 faktri dɛn nɔmɔ bin tek pat pan di ɔganayzeshɔn we dɛn de mek di industri, ɛn bɔku valv faktri dɛn nɔ bin dɔn tek pat yet pan di ɔganayzeshɔn we dɛn de mek di industri. Fɔ mek dɛn ebul fɔ ɔganayz bɔku valv faktri dɛn, ɛni rijyɔn de ɔganayz di wok we di industri de du. Shenyang Ay ɛn Midul Prɛshɔn Valv Faktɔri, Beijing Valv Faktɔri, Shanghai Valv Faktɔri, Wuhan Valv Faktɔri,Tianjin Valve Faktri, Gansu Ay ɛn Midul Prɛshɔn Valv Faktɔri, ɛn Zigong Ay Prɛshɔn Valv Faktɔri na dɛn ripɔsabl fɔ di Nɔt-Ist, Nɔt Chaina, Is Chaina, Sɛntral Sawt, Nɔtwɛst, ɛn Sawt Wɛst Rijyɔn dɛn. Insay dis tɛm, di valv industri ɛn intɛlijɛns aktiviti dɛn bin difrɛn ɛn frutful, ɛn dɛn bin rili pɔpul wit di faktri dɛn na di industri. Bikɔs ɔf di divɛlɔpmɛnt pan di industri aktiviti dɛm, di ɛkshɛnj ɔf ɛkspiriɛns ɔltɛm, ɛp dɛnsɛf ɛn lanin dɛnsɛf, i nɔ jɔs de ɛp fɔ mek di prɔdak kwaliti bɛtɛ, bɔt i de ɛp bak fɔ mek di wanwɔd ɛn padi biznɛs bitwin difrɛn faktri dɛm go bifo, so dat di valv industri dɔn fɔm wan wanwɔd ɔl, insay wanwɔd, an to an Go bifo, we de sho wan say we gɛt layf ɛn we de gro.
3. Kכriכnt di “tri mכdanizεshכn” fכ valv prodakt dεm
Fɔ fala di spirit we di tu Kaifeng mitin dɛn gɛt ɛn di opinion dɛn we di Hevi ɛn Jɛnɛral Biuro fɔ di Fɔs Ministri fɔ Mashinri, di Jɛnɛral Masin Risach Instityut wan tɛm bak ɔganayz wan big-big valv “tri mɔdanizashɔn” wok wit di aktif sɔpɔt fɔ difrɛn faktri dɛn na di industri. Di “tri mɔdanizashɔn” wok na impɔtant besik tɛknikal wok, we na wan ifektiv mɛzhɔ fɔ aksɛleret di tɛknɔlɔjik transfɔmeshɔn fɔ ɛntapraiz ɛn fɔ mek di lɛvɛl fɔ valv prodak dɛn bɛtɛ. Di valv “tri mɔdanizashɔn” wok grup de wok akɔdin to di “fo gud” (i izi fɔ yuz, izi fɔ bil, izi fɔ ripɛnt ɛn gud maching) ɛn “fo yunifayshɔn” (mɔdel, pefɔmɛns paramita, kɔnɛkshɔn ɛn ɔvala dimɛnshɔn, standad pat) prinsipul dɛn. Di men tin we de insay di wok gɛt tri tin dɛn, wan na fɔ mek di difrɛn kayn dɛn we dɛn jɔyn simpul; di ɔda wan na fɔ fɔmulayt ɛn rivays wan batch ɔf tɛknikal standad; di tɔd wan na fɔ pik ɛn dɔn di prɔdak dɛn.
4. Tɛknikal risach dɔn mek sayɛns risach go bifo
(1) Divɛlɔpmɛnt fɔ sayɛns risach tim ɛn kɔnstrɔkshɔn fɔ tɛst bays We 1969 dɔn, dɛn bin muf di Jɛnɛral Mashin Risach Instityut frɔm Pekin to Hefei, ɛn dɛn bin pwɛl di ɔrijinal flɔ rɛsistɛns tɛst divays, we bin afɛkt sayɛns risach bad bad wan. Insay 1971, sayɛnsman dɛn we de du risach bin kam bak na di tim wan afta di ɔda, ɛn di valv risach lɛbɔraytri bin go ɔp to pas 30 pipul dɛn, ɛn di ministri bin gi dɛn kɔmishɔn fɔ ɔganayz tɛknikal risach. Dɛn bil wan simpul laboratori, dɛn put wan flɔ rɛsistɛns tɛst divays, ɛn dɛn disayn ɛn mek wan patikyula prɛshɔn, pak ɛn ɔda tɛst mashin dɛn, ɛn dɛn bigin di tɛknikal risach bɔt valv silin sɔfa ɛn pak.
(2) Men tin dɛn we dɛn dɔn du Di Kaifeng Kɔnfrɛns we dɛn bin gɛt insay 1973 bin mek di tɛknikal risach plan fɔ di valv industri frɔm 1973 to 1975, ɛn dɛn bin prɔpos 39 impɔtant risach prɔjek dɛn. Pan dɛn wan ya, 8 tin dɛn de we dɛn kin yuz fɔ prosɛs di tɛmal, 16 tin dɛn we dɛn kin yuz fɔ silin, 6 tin dɛn fɔ pak, 1 tin dɛn fɔ mek ilɛktrik divays, ɛn 6 tin dɛn fɔ tɛst ɛn tɛst fɔ pefɔmɛns. Leta, na di Harbin Welding Risach Instityut, Wuhan Matirial Protɛkshɔn Risach Instityut, ɛn Hefei Jɛnɛral Mashin Risach Instityut, dɛn bin pik spɛshal pipul dɛn fɔ ɔganayz ɛn kɔdinɛt inspekshɔn dɛn we dɛn kin du ɔltɛm, ɛn dɛn bin gɛt tu wok kɔnfrɛns dɛn bɔt di bɛsis pat dɛn na di ay ɛn midul prɛshɔn valv dɛn fɔ sɔm pan di ɛkspiriɛns, fɔ ɛp dɛnsɛf ɛn fɔ chenj, ɛn dɛn bin mek 1976 -Bɛsik pat dɛn risach plan insay 1980. Tru di unanimius ɛfɔt dɛn we dɛn bin du di ol industri, big big tin dεm dεn dכn mek pan tεknikal risach wok, we dεn protεkt di divεlכpmεnt fכ sayɛns risach na di valv industri. Di men tin dɛn we kin kɔmɔt frɔm am na dɛn wan ya:
1) Tak pan di silin surface. Di siling surface risach aim fɔ sɔlv di prɔblɛm fɔ intanɛnt lik ɔfdi valv. Da tɛm de, di silin sɔfa matirial dɛn na bin men wan 20Cr13 ɛn 12Cr18Ni9, we bin gɛt lɔw hadnɛs, po wear resistans, siriɔs intanɛnt lik prɔblɛm dɛn na valv prodak, ɛn shɔt savis layf. Shenyang Valve Risach Instityut, Harbin Welding Risach Instityut ɛn Harbin Boiler Factory bin mek wan triplɛ-kɔmbayn risach tim. Afta 2 ia we dɛn bin wok tranga wan, dɛn bin mek wan nyu kayn krom-manganese silin sɔfays sɔfays matirial (20Cr12Mo8). Di matirial gɛt gud prɔses pefɔmɛns. Gud skrat resistans, lɔng savis layf, ɛn nɔ nikɛl ɛn less kromiɔm, risɔs kin bi bays pan domestik, afta tɛknikal apraiz, i rili valyu fɔ promoshɔn.
2) Fɔ ful-ɔp risach. Di rizin fɔ di pak risach na fɔ sɔlv di prɔblɛm we di valv de lik. Da tɛm de, di valv pak na bin mɔ asbest we gɛt ɔyl ɛn rɔba asbest, ɛn di siling pefɔmɛns nɔ bin fayn, we bin mek di valv lik bad bad wan. Insay 1967, di Jɛnɛral Mashin Risach Instityut bin ɔganayz wan tim we de du invɛstishɔn fɔ lik we de na do fɔ chɛk sɔm kemikal plant dɛn, ɔyl rifinɛri ɛn pawa plant dɛn, ɛn afta dat dɛn bin aktiv wan fɔ du anti-kɔrɛshɔn tɛst risach pan pak ɛn valv stem dɛn.
3) Prodakt pefɔmɛns tɛst ɛn besik tiori risach. We dɛn bin de du tɛknikal risach, .di valv industriɔlso strɔng fɔ du prodakt pefɔmɛns tɛst ɛn besik tiori risach, ɛn ajɔst bɔku rizɔlt.
5. Kכriכnt tεknכlכjik transfכmeshכn fכ εntapraiz
Afta di Kaifeng Kɔnfrɛns insay 1973, di wan ol industri bin du tɛknɔlɔjik transfɔmeshɔn. Di men prɔblɛm dɛn we bin de na di valv industri da tɛm de: Fɔs, di we aw dɛn bin de du di wok bin de bak, dɛn bin de mek di kastin wit an ɔl, dɛn bin de yuz wan pat pan di kast, ɛn dɛn bin de yuz jenɛral-pɔpɔs mashin tul dɛn ɛn jenɛral-pɔpɔs fiks dɛn fɔ kol wok. Na bikɔs di vayriet ɛn spɛsifikɛshɔn dɛn fɔ ɛni faktri de duplikɛt pasmak, ɛn di nɔmba bɔku na di wan ol kɔntri, bɔt afta dɛn dɔn sheb ɛni faktri, di prodakshɔn batch rili smɔl, we de afɛkt di ɛksɛrshɔn fɔ di prodakshɔn kapasiti. Fɔ ansa di prɔblɛm dɛn we wi dɔn tɔk bɔt, di Hevi ɛn Jɛnɛral Biuro fɔ di Fɔs Ministri fɔ Mashinri bin put dɛn tin ya: ɔganayz di ay ɛn midul prɛshɔn valv faktri dɛn we de naw, mek wanwɔd planin, sheb di wokman dɛn wit sɛns, ɛn mek bɔku bɔku prodakshɔn dɛn go bifo; adopt advans teknɔlɔji, mek prodakshɔn layn dɛn, ɛn wok togɛda na di men faktri dɛn ɛn blank dɛn. Dɛn dɔn mek 4 kast stɛl blank prodakshɔn layn dɛn na di stɛl kastin wokshɔp, ɛn dɛn dɔn mek 10 kol prɔsesin prodakshɔn layn dɛn fɔ pat dɛn na siks ki faktri dɛn; wan totɛl we na 52 milyɔn yuan dɔn invɛst insay tɛknɔlɔjik transfɔmeshɔn.
. Prɛsishɔn kastin kin riliys chip-lɛs ɔ ivin chip-fri mashin. I fayn fɔ get, pak gland ɛn valv bɔdi ɛn bɔnɛt fɔ smɔl-dayamita valv dɛn, wit klia ikɔmik bɛnifit dɛn. Insay 1969, Shanghai Lianggong Valv Faktɔri bin fɔs yuz di prɛsishɔn kastin prɔses fɔ valv prodakshɔn, fɔ PN16, DN50 get valv bɔdi,
(2) Transfɔmeshɔn fɔ kol wok teknɔlɔji Insay di transfɔmeshɔn fɔ kol wok teknɔlɔji, dɛn de yuz spɛshal mashin tul ɛn prodakshɔn layn dɛn na di valv industri. As ali as 1964, Shanghai Valve No. 7 Factory bin disayn ɛn mek di get valv bɔdi krawl tayp sɛmi-ɔtomɛtik prodakshɔn layn, we na di fɔs lɔw-prɛshɔn valv sɛmi-ɔtomɛtik prodakshɔn layn na di valv industri. Afta dat, Shanghai Valve No. 5 Factory disayn ɛn mek wan sɛmi-ɔtomɛtik prodakshɔn layn fɔ DN50 ~ DN100 lɔw-prɛshɔn glob valv bɔdi ɛn bɔnɛt insay 1966.
6. Divεlכp nyu vεryut dεm tranga wan εn impruv di lεvεl fכ komplit sεt dεm
Fɔ mek dɛn ebul fɔ mit di nid fɔ big-big kɔmplit sɛt dɛn fɔ ikwipmɛnt lɛk petrolium, kemikal industri, ilɛktrik pawa, mɛtalɔji ɛn petrokemik industri, di valv industri de tray tranga wan fɔ divɛlɔp nyu prɔdak dɛn di sem tɛm we tɛknɔlɔjik transfɔmeshɔn de, we dɔn mek di maching lɛvɛl fɔ valv prodak dɛn bɛtɛ.
03 Sɔmari
We wi luk bak pan 1967-1978, di divɛlɔpmɛnt fɔ di...valv wan tɛm, di industri bin rili afɛkt. Bikɔs ɔf di kwik divɛlɔpmɛnt fɔ petrolium, kemikal, ilɛktrik pawa, mɛtalɔji ɛn kol industri, ay ɛn midul prɛshɔn valv dɛn dɔn bi “shɔt tɛm prodak” fɔ sɔm tɛm. Insay 1972, di ɔganayzeshɔn we de mek di valv industri bigin fɔ bigin bak ɛn du di wok dɛn we dɛn de du. Afta di tu Kaifeng kɔnfrɛns dɛn, dɛn bin du “tri mɔdanizashɔn” ɛn tɛnki risach wok wit trɛnk, we mek wan wef fɔ chenj di tɛknɔlɔji na di wan ol industri. Insay 1975, di valv industri bigin fɔ kɔrɛkt, ɛn di industri prodakshɔn tek wan tɔn fɔ bɛtɛ.
Insay 1973, di Stet Planin Kɔmishɔn bin gri fɔ di infrastukchɔ mɛsej fɔ mek dɛn prodyuz ay ɛn midul prɛshɔn mɔvalv dɛn. Afta di invɛstmɛnt, di valv industri dɔn du pɔtnɛshɛl transfɔmeshɔn. Tru teknɔlɔji transfɔmeshɔn ɛn prɔmoshɔn, dɛn dɔn adopt sɔm advans tɛknɔlɔji dɛn, so dat di lɛvɛl fɔ kol prɔsesin na di wan ol industri dɔn impɔtant to wan patikyula mak, ɛn di digri fɔ mɛkanayzeshɔn fɔ tɛmal prɔsesin dɔn impɔtant to sɔm mak. Afta dɛn dɔn promot di plasma sprɛy wɛldin prɔses, dɛn dɔn impɔtant di prɔdak kwaliti fɔ di ay ɛn midul prɛshɔn valv dɛn bɔku bɔku wan, ɛn di prɔblɛm we gɛt fɔ du wit “wan shɔt ɛn tu lik” dɔn impɔtant bak. Wit di komplitishon en funkshon of 32 infrastrakcha meja projek, China in valv indastri get strong faundashon en big prodakshon potenshal. Frɔm 1970, di autput fɔ ay ɛn midul prɛshɔn valv dɛn dɔn kɔntinyu fɔ gro. Frɔm 1972 to 1975, di autput inkri frɔm 21,284t to 38,500t, wit net inkris we na 17,216t insay 4 ia, we ikwal to di ɛni ia autput insay 1970. Di ɛni ia autput fɔ lɔw-prɛshɔn valv dɛn dɔn stebul na di lɛvɛl we na 70,000 to 80,000 tan. Insay dis tɛm, .di valv industri bin mek nyu prɔdak dɛn wit trɛnk, nɔto jɔs di difrɛn kayn jenɛral-pɔpɔs valv dɛn nɔmɔ dɛn dɔn divɛlɔp bɔku bɔku wan, bɔt spɛshal valv dɛn fɔ pawa steshɔn, paip layn, ɔlta-ay prɛshɔn, lɔw tɛmpracha ɛn nyuklia industri, ɛrospɛs ɛn ɔda spɛshal valv dɛn bak dɔn divɛlɔp bɔku bɔku wan. If di 1960s na bin di tɛm we dɛn bin de mek big big divɛlɔpmɛnt fɔ jenɛral-pɔpɔs valv dɛn, den di 1970s na bin tɛm we dɛn bin de divɛlɔp spɛshal valv dɛn. Di sɔpɔtin kapasiti fɔ domestikvalv dɛn dɔn rili impɔtant, we de basically mit di divɛlɔpmɛnt nid dɛm fɔ difrɛn sɛktɔ dɛm na di nashɔnal ikɔmi.
