Isangoi-valvei-fastener, ukupakisha kanye nenqubo yokukhiqiza i-fastener ye-gasket material
Izinto zokusetshenziswa zezinsimbi ze-valve zesango, izinto zokupakisha, izinto zokwakha ze-gasket nokukhetha, izibophelelo ikakhulukazi zifaka amabhawodi, amabhawodi anamakhanda amaningi namantongomane. Izixhumi zithwala ngokuqondile amandla kumavalvu esango, abaluleke kakhulu ukugwema ukulahleka kwemidiya. Ngakho-ke, izinto zokusetshenziswa ezikhethiwe kufanele ziqinisekise amandla anele kanye nokuqina kokuphuka ekushiseni kwesicelo.
1. Izinto zokusetshenziswa zama-fasteners
Ama-fasteners ikakhulukazi afaka amabhawodi, amabhawodi anamakhanda amaningi namantongomane. Izinsimbi zithwala ngokuqondile amandla kumavalvu esango, abaluleke kakhulu ukugwema ukulahleka kwemidiya. Ngakho-ke, izinto zokusetshenziswa ezikhethiwe kufanele ziqinisekise amandla anele kanye nokuqina kokuphuka ekushiseni kwesicelo.
Lapho ukhetha izinto zokubopha ngokuya ngengcindezi ephakathi nendawo, zingakhethwa ngokuya ngeThebula 5-1.
Ubukhulu obujwayelekile Pg(Mpa) izinga lokushisa eliphakathi (℃) 300350400425450530 bolt
Inqubo yokwelapha ukushisa iyadingeka lapho kusetshenziswa izinto ze-carbon steel. Lapho izingxenye eziqinisayo zinezindinganiso ezikhethekile zokumelana nokugqwala, i-Cr17Ni2, 2Cr13, 1Cr18Ni9 nezinye insimbi engagqwali engamelana ne-asidi ingakhethwa.
Okwesibili, izinto zokusetshenziswa zokugcwalisa
Emzimbeni we-valve, ukupakisha kusetshenziselwa ukugcwalisa isikhala esingaphakathi segumbi lokupakisha i-valve eyodwa ukuze kugwenywe ukuvuza kwemidiya ngesihlalo sevalvu kanye negumbi lokupakisha i-valve eyodwa yokugeleza kwendawo yangaphakathi.
1. Isidingo sezigcwalisi
I-1) Ukumelana nokugqwala okuhle, ukupakisha kanye nokuxhumana okuphakathi, kumele ukwazi ukumelana nokugqwala kwe-medium.
2) Isakhiwo esihlangene, ukupakisha akuvuzi ngaphansi kwethonya lokushisa eliphakathi nendawo nokusebenza.
I-3) Ukumelana nokungqubuzana okuphansi ukunciphisa i-torque yokushayisana phakathi kwesihlalo nokupakisha.
2, uhlobo lokupakisha
Ukupakisha kungahlukaniswa kube ukupakisha okuthambile kwepulasitiki nokupakisha kanzima izinhlobo ezimbili:
1) Ipulasitiki ethambile yokugcwalisa: yenziwe ngezinto zokutshala eziluhlaza, okungukuthi, ilineni, ukotini, ilineni, njll., noma ngamaminerali, okungukuthi ukotini we-glass fiber, noma nge-glass fiber cotton enocingo lwensimbi kanye nentambo ye-graphite eboshwe ngaphandle; futhi kugxiliswe kusigcwali esakhayo, kanye namathuba amasha ezinto ezingavuthiwe zokugcwalisa i-graphite eminyakeni yamuva. Ukupakisha impahla yezitshalo eziluhlaza kubiza kakhulu, ikakhulukazi kusetshenziselwa ama-valve okucindezela okuphansi ngaphakathi kuka-100 ℃; Ukupakishwa kwamaminerali kulungele i-valve yesango engu-450-500 ℃. Eminyakeni yamuva nje, ukwakhiwa kwe-plastic O-ring njenge-filler kuya ngokuya kuduma, kodwa izinga lokushisa eliphakathi ngokuvamile lilawulwa ngaphakathi kwe-60 ℃. Ukupakisha ekushiseni okuphezulu kanye ne-valve yokucindezela okuphezulu nakho kwenziwa nge-asbestos ehlanzekile ne-flake graphite powder.
I-2) Ukupakisha okuqinile: ukupakisha okwenziwe ngezinto zensimbi noma insimbi exutshwe ne-asbestos, i-graphite yokuhlanzeka okuphezulu kanye ne-polytetrafluoroethylene ukucindezela ukubala nokwenza ukupakisha, isicelo sokupakisha insimbi sincane.
3, ukukhethwa ukugxusha
Ukukhethwa kokugcwalisa kufanele kusekelwe kokuphakathi, izinga lokushisa kanye nengcindezi yokukhetha, izinto zokusetshenziswa ezivamile zinamaphuzu alandelayo:
1) Amafutha endwangu ye-asbestos, angakhethwa ngokusho kweThebula 5-2.
2) Indwangu ye-asbestos yepulasitiki: ingakhethwa ngokusho kweThebula 5-3.
3) Indwangu ye-asbestos yokuhlanzeka okuphezulu kwe-graphite: indwangu ye-asbestos ehlanganiswe ne-flake graphite, izinga lokushisa lingasetshenziswa ngaphezu kuka-450 ℃, ingcindezi yokusebenza ingafinyelela ku-16Mpa, ngokuvamile efanelekile umusi wokucindezela okuphezulu. Muva nje futhi kancane kancane ukusetshenziswa kokugcwalisa ifonti yengcindezi yabantu abadala, ukubekwa kwejubane ethangeni, isakhiwo esihlangene.
4) i-polytetrafluoroethylene: Lesi isigcwalisi esisetshenziswa kabanzi kulesi sigaba. Itholakala ikakhulukazi endaweni ebolayo, kodwa izinga lokushisa alikwazi ukuba ngaphezu kuka-200 ℃. Ngokuvamile, yenziwe nge-sppressor noma imoto yenduku eyindilinga, njengoba kukhonjisiwe kuMfanekiso 5-1 ngezansi.

Uhlobo lwe-Screw: umshini wokugcoba umshini wekhanda; Kuzoba khona umshini wokubhoboza we-punch wokufa okubili, umshini wokubhoboza we-punch wokufa okubili, umshini wokubhoboza obulalayo abathathu, umshini wokubhoboza we-punch abathathu, umshini wokubhoboza kane wokufa, umshini wokubhoboza oyisihlanu wokufa, umshini wokubhoboza oyisithupha, umshini wokubhoboza oyisithupha, kanye nohlobo ngalunye ngokusho kobukhulu bochungechunge. , okufana ne-die two punch ku: 0# umshini, umshini wemizuzu, isandiso esingu-2, umshini owodwa nohhafu, isandiso sokuthathu lezi...
Imishini ebalulekile yokukhiqiza izinsimbi:
I-1, isigaba sesikulufa: umshini wokuhlikihla umshini wekhanda; Kuzoba khona umshini wokubhoboza we-die two, umshini wokubhoboza wokufa ababili, abathathu bafe abathathu, umshini wokubhoboza abathathu, abane bafe umshini wokubhoboza, abahlanu bafe abahlanu, abayisithupha bafe abayisithupha, futhi ngamunye uhlukaniswe uchungechunge ngokusho kwe usayizi, njenge-die two punching into: 0# umshini, umshini wemizuzu, isandiso esingu-2, umshini owodwa nohhafu, isandiso esithathu;
2, amantongomane: amantongomane extrusion abandayo ukwakha umshini othomathikhi eshaya;
3. Uhlobo lwe-gasket: i-punch yesivinini esikhulu;
4, amazinyo: umshini wokugoqa ucingo;
5, pin class: CNC lathe CNC lathe CNC umshini wokugaya;
6, ukuguqula izingxenye: CNC umshini wokugaya; Isikhungo sokucubungula;
Ngokusho kobuchwepheshe bokucubungula, izinsimbi zingahlukaniswa zibe ukubumba okushisayo nokubandayo, okungukuthi, i-pier eshisayo kanye ne-cold pier (extrusion processing).
Ngokusho kokuhlolwa okubandayo kwe-extrusion (i-cold top forging), kunqunywa ukuthi:
Ngokuvamile, izinto zokusetshenziswa zamabhawodi ekhanda le-hexagon yangaphandle kufanele ziqinisekise ukuthi ukucindezela okungenani ku-1/20(l [ubude obuhlobene besampula] ukuhlolwa · igridi, kanye namantongomane abandayo aphakeme, izikulufu ezibandayo ze-hexagon namabhawudi aseFrance, kufanele qinisekisa ukuthi ukuhlolwa kokuchezuka kwengcindezi engu-11311 kufinyelela ezingeni.
Ukucaciswa kwezinto ezingavuthiwe zenqubo yokucasula okubandayo nokushisayo
Ubulukhuni bezinto ezijwayelekile ze-pier ebandayo buphansi kancane, futhi ipulasitiki ingcono, ehambisana ne-plasticity deformation lapho i-pier ebandayo ikhiqizwa futhi icutshungulwa futhi igoqwe. Insimbi enekhabhoni ephansi noma ukuvikelwa kwemvelo kwekhabhoni ephansi, insimbi ye-carbon carbon steel idinga ukuncibilika, ukuqina okucishayo
Ukubukeka kwezinto ezisetshenziswayo ezijwayelekile kunqubo yesihloko esishisayo kungcono. Izinga lokushisa lokushisa alikwazi ukuvela isimo sekristalu esimahhadla, ngaphandle kwalokho ungqimba lwe-oxidation luthinta ngqo ukubukeka kwekhwalithi yomkhiqizo.
Ukukhiqizwa kwe-fastener nezinyathelo zokucubungula: i-disk element - quenching - pickling passivation - intambo yokudweba - ikhanda - amazinyo agijimayo - inqubo yokushisa ukushisa - inqubo ye-electroplating - ukupakishwa kwangaphandle Lena inqubo yokuhlanganisa ibholithi.
Iyunithi yediski: ibhekisela kukhebuli oyithengile futhi
Ukucisha: Kwenyusa ubulukhuni bekhebula. (Le nqubo ibalulekile, futhi manje isetshenziswa esithandweni somlilo esiqhubekayo sokushisa ukucindezeleka okuphezulu)
I-Pickling passivation: iwukugeza ukugqwala, izinsalela phezu kwekhebula
Donsa ucingo: Donsa ucingo uphume endaweni oyidingayo ukuze wenze ibhawodi
Inhloko: Inhloko yebhawodi ikhishwa ngokubunjwa okubandayo kwe-extrusion. (Uma ingaphezu kwe-M20 bolts, idinga ukubomvu, okungukuthi, udinga ukufudumala bese ushaya ikhanda, kodwa lolo hlobo lwe-bolt surface aluhle kakhulu, ngenxa yongqimba lwe-oxide)
Ukubumba amazinyo: kubhekisela esikhaleni nesikulufa samazinyo esidingekayo
Inqubo yokwelapha ukushisa: Le nqubo ibaluleke kakhulu ukucacisa amazinga okusebenza kwebhawudi
Inqubo ye-Electroplating: Ingaphezulu lensimbi liphathwa nge-hue yendawo oyifunayo
Isikhathi sokuthumela: Feb-21-2023
