I-valve yokusakazauma iphonswa ku-valve, izinga lokucindezela kwe-valve yokuphonsa elijwayelekile liphansi kakhulu (njenge-PN16, PN25, PN40, kodwa futhi kukhona ukucindezela okuphezulu, okungaba yi-1500LD, 2500LB), iningi le-caliber lingaphezu kwe-DN50.Ama-valve okwakhazikhiqizwe ngobumba. Ngokuvamile zisetshenziswa kumapayipi ekhwalithi ephezulu. Isilinganiso sincane, futhi ngokuvamile singaphansi kwe-DN50.
A, ukuphonsa
1. Ukukhipha: inqubo yokuncibilikisa insimbi ibe uketshezi oluhlangabezana nezidingo ezithile bese luthululelwa esikhumbeni sokukhipha. Ngemva kokupholisa nokuqinisa, ukukhipha (izingxenye noma okungenalutho) kutholakala ngesimo, usayizi kanye nokusebenza okunqunyiwe. Ubuchwepheshe obuyisisekelo bomkhakha wokukhiqiza imishini yesimanje.
2, ukukhiqizwa kokubumba kwezindleko ezingenalutho kuphansi, ngesimo esiyinkimbinkimbi, ikakhulukazi ngezingxenye eziyinkimbinkimbi zomgodi, okuningi kungabonisa umnotho wayo; Ngesikhathi esifanayo, inokuvumelana nezimo okubanzi kanye nezakhiwo ezinhle zemishini eziphelele.
3, kodwa izinto ezidingekayo ekukhiqizeni ubumba (njengensimbi, izinkuni, uphethiloli, izinto zokubumba, njll.) kanye nemishini (njengesithando sensimbi, umshini wokuxuba isihlabathi, umshini wokubumba, umshini wokwenza i-core, i-shaker, umshini wokuqhumisa ngokudubula, ipuleti lensimbi elibunjiwe, njll.) ziningi kakhulu, futhi zizokhiqiza uthuli, igesi eyingozi nomsindo futhi zingcolise imvelo.
4. Ukubumba uhlobo lobuchwepheshe bokusebenza kwensimbi obusebenza ngokushisa obunomlando weminyaka engaba ngu-6000. Ngo-3200 BC, ukubumba amaxoxo ethusi kwavela eMesopotamia. Phakathi kwekhulu le-13 BC nele-10 BC, iShayina isingene esikhathini sokubumba ithusi, inqubo isifinyelele ezingeni eliphakeme impela, njengeShang Dynasty Simuwu square Ding enesisindo esingu-875 kg, iWarring States Dynasty Jinghou Yi Zunpan kanye nesibuko esibonakalayo seWestern Han Dynasty yimikhiqizo emele ukubumba kwasendulo. Ukubumba kwasekuqaleni kwakuthonywe kakhulu yizitsha zobumba, futhi iningi lokubumba kwakungamathuluzi noma izitsha zokukhiqiza kwezolimo, inkolo, impilo nezinye izici, ezinombala wobuciko oqinile. Ngo-513 BC, iShayina yakhiqiza insimbi yokuqala eqoshiwe emarekhodi abhaliwe emhlabeni - iJin Casting Ding (cishe ama-270 kg). Cishe ngekhulu lesi-8, iYurophu yaqala ukukhiqiza insimbi eqoshiwe. Ngemva kwenguquko yezimboni ngekhulu le-18, ukubumba kwangena enkathini entsha yokukhonza izimboni ezinkulu. Ekhulwini lama-20, intuthuko esheshayo yokucubungula, ithuthukise insimbi ethambile, insimbi ethambile ethambile, insimbi engagqwali enekhabhoni ephansi kakhulu kanye nethusi le-aluminium, i-aluminium silicon, i-aluminium magnesium alloy, isisekelo se-titanium, i-nickel base alloy kanye nezinye izinto zensimbi yokucubungula, futhi yasungula inqubo entsha yensimbi empunga yokucubungula ukuze yenze ukwelashwa. Ngemuva kweminyaka yama-1950, ubuchwepheshe obusha obufana nokubumba isihlabathi esimanzi ngomfutho ophezulu, ukubumba isihlabathi esiqinile ngamakhemikhali, ukwenza i-core, ukubumba ingcindezi engemihle, kanye nokunye ukubumba okukhethekile kanye nokuqhuma kwesibhamu kwaqalwa.
5. Kunezinhlobo eziningi zokukhipha. Ngokwendlela yokwenza imodeli, ihlukaniswe ngokwesiko ibe yi-0 ejwayelekile yokukhipha isihlabathi, okuhlanganisa uhlobo lwesihlabathi esimanzi, uhlobo lwesihlabathi esomile kanye nohlobo lwesihlabathi sokuqina kwamakhemikhali 3. (2) ukukhishwa okukhethekile, izinto zokubumba ezicindezelwe futhi kungahlukaniswa kube isihlabathi semvelo samaminerali njengezinto zokubumba ezikhethekile (isb., ukukhishwa kwezimali, ukukhishwa kwesikhunta, isisekelo sokukhipha isikhunta segobolondo, ukukhishwa kwengcindezi engemihle, ukukhishwa kwesikhunta, ukukhishwa kwesikhunta se-ceramic, njll.) kanye nensimbi njengezinto eziyinhloko zokukhipha ezikhethekile (njengokuphonswa kwesikhunta sensimbi, ukukhishwa kwengcindezi, ukukhishwa okuqhubekayo, ukukhishwa kwengcindezi ephansi, ukukhishwa kwe-centrifugal, njll.).
6, inqubo yokuphonsa imvamisa ifaka: (ukuphonsa (izitsha) kwenza insimbi ewuketshezi i-cast eqinile, ukuphonsa ngokwezinto zokwakha kungahlukaniswa kube isikhunta sesihlabathi, insimbi, i-ceramic, udaka, i-graphite, njll., kungahlukaniswa ngokusetshenziswa okulahlwayo, uhlobo oluhlala njalo noluhlala njalo, ikhwalithi yokulungiselela isikhunta yizinto eziyinhloko ezithonya ikhwalithi yokuphonsa; Ukuncibilika nokuthululwa kwensimbi ephonsa, insimbi ephonsa (i-alloy ephonsa) ikakhulukazi kufaka phakathi insimbi ephonsa, insimbi ephonsa kanye ne-alloy engeyona i-ferrous; (3) ukwelashwa nokuhlolwa kokuphonsa, ukwelashwa kokuphonsa, kufaka phakathi ukususwa kwemizimba yangaphandle eyinhloko kanye neyokuphonsa, ukususwa kwe-riser, i-burr yokugaya ifosholo kanye nokunye ukuvela, ukwelashwa kokushisa, ukubumba, ukwelashwa kokulwa nokugqwala kanye nomshini onzima. I-valve yepompo yokungena
Ukwakhiwa kwesibili
1, ukubumba: ukusetshenziswa kwemishini yokubumba ekucindezelweni kwensimbi ye-billet, ukuguqulwa kwepulasitiki ukuthola izakhiwo ezithile zemishini, ukuma nobukhulu obuthile bendlela yokucubungula ukubumba.
2, enye yezingxenye ezimbili eziyinhloko zokufaka. Ngokufaka kungasusa insimbi njengoba imigodi yokushisela evulekile, izakhiwo zemishini zokufaka ngokuvamile zingcono kunezingqimba ezifanayo zezinto. Ezingxenyeni ezibalulekile ezinomthwalo omkhulu nezimo zokusebenza ezinzima emishinini, ukufaka izinto zokufaka ...
3, ukubumba ngokwendlela yokwakha kungahlukaniswa kube: 0 ukubumba okuvulekile (ukubumba okukhululekile). Ukusetshenziswa kwamandla noma ingcindezi ukwenza insimbi phakathi kokubumba okubili okulwa nensimbi (ibhulokhi ye-anvil) okuphezulu nokuphansi ukuze kutholakale ukubumba okudingekayo, ikakhulukazi ukubumba ngesandla kanye nokubumba ngomshini. 2 Ukubumba imodi evaliwe. Isikhala sensimbi siguquguquka ngaphansi kwengcindezi ekamelweni lokubumba elinesimo esithile, kanti ukubumba kungahlukaniswa kube ukubumba okubandayo, ukubumba okujikelezayo, ukubumba okujikelezayo, ukukhuphula nokunye. Ngokusho kokubumba, izinga lokushisa lokubumba lingahlukaniswa libe ukubumba okushisayo (izinga lokushisa lokucubungula liphakeme kunezinga lokushisa lokubumba kabusha lensimbi engenalutho), ukubumba okufudumele (okuphansi kunezinga lokushisa lokubumba kabusha) kanye nokubumba okubandayo (izinga lokushisa elivamile).
4, izinto zokwakha ngokuyinhloko ziqukethe izingxenye ezahlukahlukene zensimbi yekhabhoni nensimbi ye-alloy, kulandele i-aluminium, i-magnesium, i-titanium, ithusi kanye ne-alloy yayo. Isimo sokuqala sezinto zokwakha sihlanganisa izinduku, amaketanga okuphonsa, izimpushana zensimbi kanye nezinsimbi eziwuketshezi. Isilinganiso sendawo yesigaba sensimbi ngaphambi kokuguqulwa kwendawo yesigaba se-die ngemuva kokuguqulwa sibizwa ngokuthi isilinganiso sokwakha. Ukukhetha okulungile kokwakha kunokuthuthukisa ikhwalithi yomkhiqizo, ukunciphisa izindleko kunobuhlobo obuhle.
