Isangoivalvei-fastener, ukupakisha kunye ne-gasket yezixhobo zokukhetha inkqubo yokuvelisa i-fastener
Izinto ezikrwada zokuqhoboshela ivalvu yesango, izinto zokupakisha, izixhobo ze-gasket kunye nokukhethwa, izibophelelo ikakhulu ziquka iibholiti, iibholiti zentloko ezininzi kunye namantongomane. Izibophelelo zithwala ngokuthe ngqo amandla kwiivalvu zesango, ezibaluleke kakhulu ukuphepha ukulahleka kweendaba. Ngoko ke, izinto ezikhethiweyo ezikhethiweyo kufuneka ziqinisekise amandla okwaneleyo kunye nokuqina kweqhekeza kwiqondo lokushisa lesicelo.
1. Imathiriyeli ekrwada yeefasteners
Iifasteners ikakhulu ziquka iibholiti, iibholiti zentloko ezininzi kunye namantongomane. Izibophelelo zithwala ngokuthe ngqo amandla kwiivalvu zesango, ezibaluleke kakhulu ukuphepha ukulahleka kweendaba. Ngoko ke, izinto ezikhethiweyo ezikhethiweyo kufuneka ziqinisekise amandla okwaneleyo kunye nokuqina kweqhekeza kwiqondo lokushisa lesicelo.
Xa ukhetha izinto ze-fastener ngokoxinzelelo oluphakathi kunye nokushisa, zinokukhethwa ngokweThebhile 5-1.
Idayamitha eqhelekileyo Pg(Mpa) ubushushu obuphakathi (℃) 300350400425450530 bolt
Inkqubo yokushisa ukushisa iyadingeka xa kusetyenziswa izinto ze-carbon steel. Xa iindawo eziqinisiweyo zinemigangatho ekhethekileyo yokumelana nokubola, i-Cr17Ni2, i-2Cr13, i-1Cr18Ni9 kunye nezinye i-acids stainless resistant steel zingakhethwa.
Eyesibini, i-filler ekrwada
Kumzimba wevalvu, ukupakishwa kusetyenziselwa ukugcwalisa isithuba sangaphakathi segumbi lokupakisha ivalve enye ukunqanda ukuvuza kwemithombo yeendaba ngesitulo sevalve kunye negumbi lokupakisha ivalve enye yendawo yangaphakathi.
1. Imfuno yokugcwaliswa
I-1) Ukumelana nokugqwesa okulungileyo, ukupakisha kunye noqhagamshelwano oluphakathi, kufuneka lukwazi ukuxhathisa ukubola kwe-medium.
2) Isakhiwo esiqinileyo, ukupakisha akuvuzi phantsi kwefuthe lobushushu obuphakathi kunye nokusebenza.
I-3) Ukuxhatshazwa okuphantsi kokunciphisa ukunciphisa i-torque ye-friction phakathi kwesihlalo kunye nokupakisha.
2, uhlobo lokupakisha
Ukupakisha kunokwahlulwa kube yiplastiki ethambileyo yokupakisha kunye nokupakisha kanzima kwiindidi ezimbini:
1) Isithambiso seplastiki esithambileyo: senziwe ngezinto zokutyala eziluhlaza, ezizezi, ilinen, iqhaphu, ilinen, njl. kunye nomhlaba kwi-filling filler, kunye namathuba amatsha ezinto eziguquguqukayo zegraphite filler kule minyaka yakutsha nje. Ukupakisha izinto zezityalo eziluhlaza kuneendleko eziphezulu, ikakhulu ezisetyenziselwa iivalvu zoxinzelelo oluphantsi ngaphakathi kwe-100 ℃; Ukupakishwa kwamaminerali kufanelekile kwi-valve yesango ye-450-500 ℃. Kwiminyaka yakutshanje, ukwakhiwa kwe-O-ring yeplastiki njenge-filler ithandwa ngokuthe ngcembe, kodwa ubushushu obuphakathi bulawulwa ngokubanzi ngaphakathi kwe-60 ℃. Ukupakishwa kwiqondo lokushisa eliphezulu kunye ne-valve yoxinzelelo oluphezulu lwenziwe nge-asbestos ecocekileyo kunye ne-flake ye-graphite powder.
2) Ukupakisha okunzima: ukupakisha okwenziwe ngezinto zetsimbi okanye isinyithi exutywe ne-asbestos, igraphite ecocekileyo kunye ne-polytetrafluoroethylene yokucofa i-calcination kunye nokwenza ukupakisha, isicelo sokupakisha isinyithi sincinci.
3, ukhetho lokuxutywa
Ukhetho lokuzalisa kufuneka lusekelwe kumbindi, ubushushu kunye noxinzelelo lokukhetha, izixhobo eziqhelekileyo eziluhlaza zinala manqaku alandelayo:
1) I-oyile kwilaphu le-asbestos, inokukhethwa ngokweThebhile 5-2.
2) Ilaphu le-asbestos yeplastiki: inokukhethwa ngokweThebhile 5-3.
I-3) ilaphu le-asbestos elicocekileyo legraphite: ilaphu le-asbestos liqatywe kwi-flake yegraphite, ubushushu bunokusetyenziswa ngaphezu kwe-450 ℃, uxinzelelo lokusebenza lunokufikelela kwi-16Mpa, lufanelekile ngokubanzi kumphunga woxinzelelo oluphezulu. Kutshanje kwaye ngokuthe ngcembe ukusetyenziswa koxinzelelo lwefonti yokugcwaliswa kwabantu abadala, ukubekwa kwesantya ethangeni, ubume obubambeneyo.
I-4) i-polytetrafluoroethylene: Le yinto esetyenziswa kakhulu ukuzalisa kweli nqanaba. Ifumaneka ngakumbi kwindawo engcolisayo, kodwa ubushushu abunakuba ngaphezulu kwe-200℃. Ngokuqhelekileyo, yenziwe nge-sppressor okanye imoto yentonga ejikelezayo, njengoko kuboniswe kuMzobo 5-1 ngezantsi.

Uhlobo lwe-Screw: umatshini wokucoca umatshini wentloko; Kuya kubakho umatshini wepunch wokufa ababini, umatshini wokufa kabini wokufa, abathathu bafa abathathu ngoomatshini, abane bafa umatshini wepunch ezine, abahlanu bafa abahlanu, abathandathu bafa umatshini wepunch ezintandathu, kwaye uhlobo ngalunye ngokobungakanani bothotho. , okufana ne-die two punch ku: 0# umatshini, umatshini wemizuzu, 2 ulwandiso, umatshini emibini enesiqingatha, ulwandiso oluthathu olu...
Izixhobo eziphambili zokwenza iziqhoboshi:
I-1, iklasi ye-screw: umatshini wokucoca umatshini wentloko; Kuya kubakho umatshini wokungqiya kabini wokufa, ababini bafa abane, abathathu bafa abathathu ngoomatshini, abane bafa abane, abahlanu bafa abahlanu, abathandathu bafa abathandathu, kwaye ngamnye wahlulwe waba luluhlu ubukhulu, ezifana die ezimbini punching zibe: 0 # umatshini, umatshini imizuzu, 2 ulwandiso, umatshini ezimbini ezinesiqingatha, ulwandiso ezintathu;
2, amantongomane: amantongomane extrusion abandayo ukwenza umatshini ozenzekelayo ukutephulela;
3. Uhlobo lweGasket: i-punch yesantya esiphezulu;
4, amazinyo: ucingo rolling machine;
I-5, iklasi ye-pin: i-CNC lathe ye-CNC i-lathe ye-CNC yomshini wokusila;
I-6, iinxalenye zokuguqula: umatshini wokugaya i-CNC; Iziko lokulungisa;
Ngokwetekhnoloji yokucubungula, i-fasteners inokwahlulwa ibe yi-forging eshushu kunye ne-forging ebandayo, oko kukuthi, i-pier eshushu kunye ne-pier ebandayo (i-extrusion processing).
Ngokwe-extrusion ebandayo (i-cold top forging) ilinge, kumiselwa ukuba:
Ngokubanzi, izinto ezikrwada zeebholiti zehexagon zangaphandle kufuneka ziqinisekise ukuba uxinzelelo luyi-1/20 ubuncinane (l [ubude obunxulumene nesampulu] uvavanyo · igridi, kunye namantongomane aphezulu abandayo, izikrufu zehexagon ezibandayo kunye neebholiti zesiFrentshi, kufuneka qinisekisa ukuba uvavanyo lokutenxa koxinzelelo lwe-11311 lufikelela kumgangatho.
Ukucaciswa kwemathiriyeli ekrwada yenkqubo yokuphazamiseka ebandayo kunye neshushu
Ubunzima bezinto eziqhelekileyo ze-pier ezibandayo ziphantsi kancinci, kwaye iplastiki ingcono, ehambelana nokuguqulwa kweplastiki xa i-pier ebandayo ikhiqizwa kwaye iqhutywe kwaye iqengqeleke. Intsimbi ephantsi yekhabhoni okanye ukukhuselwa kokusingqongileyo kwekhabhoni ephantsi, i-carbon carbon steel medium kufuneka ifakwe i-annealed, ukucima ubunzima
Ukubonakala kwezinto eziqhelekileyo ezisemgangathweni kwinkqubo yesihloko esishushu kungcono. Ubushushu bobushushu alinakuvela kwimeko yekristale erhabaxa, kungenjalo umaleko we-oxidation uchaphazela ngqo ukubonakala komgangatho wemveliso.
Ukuveliswa kwe-Fastener kunye namanyathelo okucubungula: i-disk element - ukucima - i-pickling passivation - umzobo wocingo - intloko - ukuqengqeleka kwamazinyo - inkqubo yonyango lokushisa - inkqubo ye-electroplating - ukupakishwa kwangaphandle Le yinkqubo yokuhlanganiswa kwebholithi.
Iyunithi yediski: ibhekisa kwintambo oyithengileyo
Ukucima: Yandisa ubulukhuni bentambo. (Le nkqubo ibalulekile, kwaye ngoku isetyenziswa kwisithando somlilo esiqhubekayo soxinzelelo oluphezulu)
Pickling passivation: kukuhlamba umhlwa, intsalela kumphezulu wentambo
Tsala ucingo: Tsala ucingo luphume kwindawo owufunayo ukwenza ibholithi
Intloko: Intloko yebholithi ikhutshiwe yi-extrusion ebandayo eyenza. (Ukuba ingaphezulu kwe-M20 bolts, kufuneka ibe bomvu, oko kukuthi, kufuneka ufudumale uze ubethe intloko, kodwa olo hlobo lwebholithi alukho luhle kakhulu, ngenxa ye-oxide layer)
Ukubumba amazinyo: kubhekiselele kwisithuba esifunekayo samazinyo kunye nesikrufu
Inkqubo yokunyanga ukushisa: Le nkqubo ibaluleke kakhulu ukucacisa amanqanaba okusebenza kwebholithi
Inkqubo ye-Electroplating: Umphezulu wesinyithi uphathwa kwi-hue yomhlaba oyifunayo
