Xa abantu abaninzi besiva 'ivalve yentsimbi engenastainless', baba nomfanekiso wehardware emenyezelayo, engenakonakala. Leyo yimbono yokuqala ephosakeleyo. Inyani ikude kakhulu kwaye inomdla ngakumbi. Ayisiyomathiriyeli kuphela; imalunga nesakhiwo okuziinkozo ukusuka ekugaleleni, ukunyamezelana machining, ibakala ethile ukumelana cocktail ethile imichiza, kunye norhwebo-offs olungenakuthintelwa. Ndibone iiprojekthi ezininzi kakhulu ze-generic 304 okanye i-316 valve kuyo yonke into, kuphela ukujongana nokusilela kwangaphambi kwexesha ebaleni. Ipolishi yifacade nje. Ibali lokwenyani likwi-metallurgy kunye ne-craft craft emva kwayo.
Isiseko: Iqala ngokuCasa
Awukwazi ukutshiza ivalve ethembekileyo ukusuka kwindawo engalunganga. Apha kulapho amashumi eminyaka yamava, njengale nto uyifumanayo kwintsebenzo yexesha elide, ibaluleke ngokwenene. Ndikhumbula ndivavanya ibhetshi ye ivalve yentsimbi engenasici imizimba yomgca wokutya kweekhemikhali. Ephepheni, zaziyi-316L. Ngokubonakalayo, babelungile. Kodwa phantsi kovavanyo lokungena kwedayi, inethiwekhi ye-micro-shrinkage porosity yabonakala, kanye kwicandelo elibalulekileyo eludongeni. Elo bhetshi lalimiselwe indawo yekloridi. Bekuya kuba kukuvuza okulindileyo ukuba kwenzeke. Ulawulo lwenkqubo ye-Foundry-indlela abalawula ngayo ubushushu obuthululwayo, izinto zokungunda, kunye namazinga okupholisa-yinto yonke. Inkampani ebisele ikumdlalo wokuphosa ngaphezulu kweminyaka engama-30, njengeQingdao Qiangsenyuan Technology (QSY), ibiya kuzilungisa ezi ziguquguqukayo ngokuphindaphinda. Ugxininiso lwabo kubumba lweqokobhe kunye nokuphosa utyalo-mali lungundoqo kwiivalvu; ezi ndlela zibonelela ngokuchaneka okubhetele komgangatho kunye nokugqiba komphezulu kwiipaseji ezintsonkothileyo zangaphakathi xa kuthelekiswa nezinye iindlela zokugalela isanti, nto leyo ethetha ukucocwa kokulungiswa komatshini kunye nemveliso yokugqibela engaguqukiyo.
Ukukhethwa kwezinto ezibonakalayo kwinqanaba lokuphosa sesinye isigqibo esincinci. Insimbi engenasici luhlu olukhulu. Ngomgca oqhelekileyo wamanzi, i-CF8 (i-cast elingana nama-304) inokwanela. Kodwa kwizicelo zaselunxwemeni ngesitshizi setyuwa rhoqo, ujonge ibakala eliphindwe kabini, into efana neF55. Ubunzima bokuphosa butsiba ngokukhawuleza. Ukubunjwa kwe-alloy kufuneka kubanjwe ngaphakathi kwefestile eqinile kakhulu, kwaye unyango lobushushu emva kokuphosa ukufezekisa ibhalansi echanekileyo ye-ferrite-austenite ibalulekile. Ndibone iivalvu ziqhekeka ngexesha lomatshini ngenxa yokuba umjikelo wonyango lobushushu wawucinywe ngamaqondo ambalwa. Kusisikhumbuzo sokuba ukusebenza kwevalve kuvalelwe ixesha elide ngaphambi kokuba ifike kwibhentshi yendibano.
Kulapho ubungcali kwii-alloys ezikhethekileyo, njenge-nickel-based based, iba yinto efanelekileyo. Saba neprojekthi ebandakanya umphunga weacetic acid eshushu. Umgangatho we-316L ngewuhlafunwa. Isisombululo yayiyivalve yomzimba ephoswe kwi-Alloy 20Cb3. Isakhono se-Foundry yokuphatha i-exotics enjalo asiyo-bar yecala; lubuchule obungundoqo bokujongana nenkonzo eyonakalisayo. Ayikokuba nengxubevange kuluhlu; kukwazi ukuphosa ngaphandle kokubangela iinyembezi ezishushu okanye ulwahlulo.
UMatshini: Apho ukuchaneka kuhlangana khona nokusebenzayo
Ukubunjwa ngumfanekiso oqingqiweyo. Ubuchwephesha buyenza iphile. Kwaye nantsi inyani ebonakalayo: isicwangciso somatshini se ivalve yentsimbi engenasici Umzimba wahlukile kulowo webhloko yentsimbi ethambileyo. umsebenzi Stainless-nzima. Ukuba isixhobo sakho asikho bukhali, isantya sakho kunye nokutya akulunganga, uya kutshisa umphezulu kunokuba usike, udale umaleko oqinileyo, obhityileyo onokuqalisa iintanda phantsi koxinzelelo lwebhayisikile. Ndiyifunde le ndlela kabuhlungu kwangethuba, ndivelisa iseti yeevalvu zesango eziye zagalela kwaye zabanjwa ngexesha lovavanyo lokuqala loxinzelelo. Ukugqiba kwakukuhle, kodwa kusebenze kakubi.
Amaziko omatshini e-CNC abonelela ngokuphinda-phinda, kodwa ulwazi lomdwelisi lulo oluyenza ithembeke. Ulandelelwano lwemisebenzi lubalulekile. Ngaba uyayirhaxa ipokotho yesitulo phambi okanye emva kokugrumba umngxuma wesikhondo? Uwulungisa njani umzimba omile ngendlela engaqhelekanga ukuze ugqibezele ukudlula kwiflange ngaphandle kokwenza uxinzelelo? Kwiivalvu ezininzi ezintsonkothileyo, oku kuba yiphazili ye-3D. Ivenkile enamava anzulu e-CNC, onokuthi uyilinganise kwiipotfoliyo zabo kwiindawo ezifana ne-https://www.tsingtaocnc.com, ikholisa ukuba nokuhamba komsebenzi kumiliselwe. Abayikusika isinyithi nje; balawula uxinzelelo olushiyekileyo kunye nokugcina iireferensi zedatum kuzo zonke iiseti ezininzi.
Emva koko kukho ukugqiba. I-32 Ra microfinish kwisitulo sevalve yebhola inokuchazwa. Ukuphumeza oko kumphezulu wecast stainless, ngokuqhubekayo, kumakhulu eeyunithi, bubuchule. Ihlala ibandakanya indibaniselwano ye-CNC yokujika kwaye emva koko i-lapping ezinikeleyo okanye umsebenzi wokusila. Ndikhe ndandwendwela iindibano zocweyo apho eli nyathelo lokugqibela lisasenziwa ngamagcisa anamava anokuthi 'azive' isiphelo. Kukudityaniswa kwe-CNC yangoku kunye nobuchule obubambekayo obuhlala buvelisa eyona ndawo inokuthenjwa yokutywina.
INdibano kunye neMigibe yoVavanyo
Kulapho amacandelo alungileyo anokuba yivalve embi. Indibano ibonakala iqondile: beka umzimba, i-trim (isiqu, ibhola, isihlalo), kunye nokutywinwa kunye. Kodwa usathana usezinkcukacha. Impazamo eqhelekileyo kukubhuqa ngokugqithisileyo umlandeli wedlala kwivalve yesikhondo esinyukayo. Oku kuphazamisa ukupakishwa, kudala ukungqubana okugqithisileyo kwisiqu, kwaye kukhokelela ekunxibeni kwangaphambi kwexesha kunye nevalve esebenza nzima. Iimpawu zetorque zikhona ngesizathu, kodwa zihlala zingahoywa kumgangatho wevenkile ngokukhawuleza ukugqiba iodolo.
Uvavanyo yenye indawo enomahluko obanzi. Uvavanyo lweqokobhe le-hydrostatic lusemgangathweni, ngokuqinisekileyo. Kodwa ngaba uvavanyo lubandakanya uvavanyo lwesihlalo sokubetha kancinci kwiivalvu zokuvala? Kwinkonzo ebalulekileyo, kufuneka. Ndikhumbula imeko apho ibhetshi ye intsimbi engenasici iivalve zeglowubhu ziluphumelele uvavanyo lweqokobhe kodwa zavuza kakubi kuvavanyo lwesitulo. Isizathu esisisiseko sasilandelwa emva kokuphazamiseka okuncinci ngexesha lokusila kokugqibela kwediski kunye nesihlalo-ingxaki kuphela uvavanyo lwesihlalo oluya kubonisa. Umvelisi ongqongqo uya kuba neprotocol yovavanyo ehleliweyo, hayi nje ipop yoxinzelelo olunye.
Kwaye makhe sithethe ngococeko. Kwinkonzo ye-oxygen okanye izicelo zamachiza, oku kubaluleke kakhulu. Nayiphi na igrisi, uthuli, okanye amasuntswana esinyithi ashiywe kumatshini anokuba yingozi yomlilo okanye umthombo wongcoliseko. Indawo yendibano ifanele ilawulwe, yaye iinkqubo zokucoca nokufakwa kweengxowa kufuneka zibe ngqongqo. Yindleko esoloko ingahoywa eyohlula ivalve yempahla ethembeke kakhulu.
Iintsilelo zokwenyani zeHlabathi kunye neZifundo
Akukho nto ifundisa njengokungaphumeleli. Sakha safakela uthotho lweevalvu zebhola estainless ezingama-304 kumgca wokupholisa weplanti yonxweme (amanzi anebraki). Kwiinyanga ezili-18, sasijongene nokuvuza okujikeleze isiqu kunye ne-body seals. Oyena nobangela yaba kukudleka kweentanda. Ngelixa i-304 inokumelana ne-corrosion jikelele, i-micro-environment emileyo phakathi kwesiqu kunye nokupakisha, kwaye phantsi kwee-gaskets, yenze iiseli zoxinaniso lwe-oksijini. I-chlorides igxininise, kwaye i-pitting yaqala. Sitshintshele kwiivalvu ezingama-316 ezinoyilo olungcono lwe-gasket kwaye sichaze umjikelo wolondolozo rhoqo. Isifundo: Ukukhethwa kwemathiriyeli kufuneka kuthathelwe ingqalelo indawo engqongileyo ethile, kubandakanywa iindawo ezimileyo kunye neentanda.
Esinye isifundo savela kwibhayisekile eshushu. Iseti yeevalvu ze-316L ezisamente kumgca wokubuya we-condensate umphunga uqale ukuqhekeka kuqhagamshelo lwebhonethi yomzimba emva konyaka wenkonzo. Uphando lwalatha ukudinwa kwe-thermal. Ukuphosa, ngelixa isandi, sasinomxholo ophezulu wekhabhoni kwibakala (kumda ophezulu we-spec). Oku, kudibene nokufudumeza okuphindaphindiweyo ngokukhawuleza kunye nokupholisa, ukukhuthaza imvula ye-carbide kwimida yengqolowa, ukunciphisa i-ductility. Ukulungiswa yayikukukhupha iivalvu kunye nesiqinisekiso se-L-grade (ikhabhoni ephantsi) kunye nembali yonyango lobushushu obulawulwayo. Ibethelele ukuba isiqinisekiso somatshini wephepha sisiqalo, ayisosiqinisekiso.
Ukufumana kunye nexabiso leQela eliKhethekileyo
Oku kundizisa ekufuneni. Ukufumana umthengisi olawula inkqubo ukusuka kwi-melt ukuya kwivenkile yomatshini kuyinzuzo enkulu. Xa kuvela ingxaki, awubambeki kuthungelwano phakathi kwe-Foundry kunye nevenkile yomatshini utyholana. Umenzi odityanisiweyo othe nkqo, okanye onentsebenziswano eyendele nzulu njengenkampani eye yavela ngaphezulu kweminyaka engama-30 ukusuka ekufakweni kumatshini ochanekileyo, unokuwulanda umba ubuyela kwingcambu yawo. Ngaba yayikubandakanywa kwe-slag kwi-casting? Ukungcangcazela kwezixhobo ngexesha lomsebenzi womatshini wesihlanu? Banokufumanisa.
Ukujonga amandla omthengisi, njengalawo achazwe kwi-Qingdao Qiangsenyuan Technology Co., Ltd., ibalisa ibali. Ngaphezulu kwamashumi amathathu eminyaka ekujuleni nasekwenzeni, ukusebenza ngespectrum ukusuka kwintsimbi etyhidiweyo ukuya kwi-nickel alloys-leyo imbali ibonisa ukuba baye badibana kwaye basombulula uninzi lweegremlins ezithe ngqo. Iwebhusayithi yabo, https://www.tsingtaocnc.com, ibonisa ugqaliselo kwiinkqubo zokwenziwa kwezinto ezibalulekileyo ekwenziweni kweevalvu. Xa ukhangela a ivalve yentsimbi engenasici kwisicelo esinyanzelisayo, loo nkqubo yelifa lemveli ibaluleke kakhulu njengomzobo wokugqibela wemveliso. Ngumahluko phakathi kokuthenga indawo kunye nokuthenga inxalenye enobunzulu bokuqonda okwenziwe emva kwayo.
Ekugqibeleni, ivalve yentsimbi ethembekileyo ikukudityaniswa kwesinyithi esichanekileyo, ukuphosa okuchanekileyo, ukucwangciswa komatshini, kunye nokudibanisa okucokisekileyo. Kunqabile ukuba lolona khetho lufikelelekayo, kuba inyathelo ngalinye lixabisa. Kodwa kwizicelo zemizi-mveliso, iindleko zokungaphumeleli-ixesha lokuphumla, ukukhutshwa kwendalo, iingozi zokhuseleko-zinciphisa umahluko wexabiso lokuqala. Injongo asikokuthenga ivalve; kukuthenga isixhobo esivaliweyo, esinomda woxinzelelo esiya kusebenza kwangaphambili kubomi baso bokuyilwa. Kwaye oko kufuna ukujonga ngaphaya komphezulu ogudisiweyo.
