Chidziwitso choyambirira cha gaskets wamba

Tepi yopanda zitsulo

Zomwe zimagwiritsidwa ntchito nthawi zambiri sizitsulo zachitsulo, monga graphite yosinthika (<600 ° C), polytetrafluoroethylene (-200 ~ 260 ° C), bolodi lopangidwa ndi mphira.

Riboni ya Metal

StrapsShape: V, W, wavy, etc.Zinthu: 0.15 ~ 0.25 chitsulo chochepa cha carbon, chitsulo chosapanga dzimbiri, mkuwa ndi ma alloys ena osagwirizana ndi dzimbiri, etc.Function: kulamulira kulimba kwa psinjika kwa gasket, kusindikiza;Wonjezerani kuuma konse kwa gasket.

mphete yamkati

Mfundo: Mphete yamkati imakhudzana ndi madzimadzi, ndipo zinthu zake ziyenera kugonjetsedwa ndi dzimbiri za sing'anga yosindikiza.

Zida: carbon zitsulo, zitsulo zosapanga dzimbiri, dzimbiri zosagwira kasakaniza wazitsulo, etc.

Ntchito: Kupewa kusiyana pakati pa gawo losindikiza ndi chidebe kapena chitoliro cha chitoliro kuti mupewe kusiyanaku kumasokoneza kutuluka kwamadzimadzi komanso kukokoloka kwamadzi kwa gasket.Pamene kuthamanga madzimadzi mkati ndi kutentha ndi mkulu, dzimbiri mkati madzimadzi ndi abrasion ndi oopsa, madzimadzi amaletsedwa kukhalabe mu kusiyana flange, gasket kukula ndi lalikulu kapena ntchito otukukira ndi concave flange ndi nthawi zina, mphete yamkati. yakhazikitsidwa.

Kupeza mphete (ring yakunja)

Ntchito: kulimbikitsa ndikuyika bwino kwa thupi la gasket, kuletsa kukanikizana kolimba kwambiri kuti zisataye kuthekera kwa gasket ndikuletsa gasket kuti lisatayike. Zofunika: mphete yolimbikitsira yakunja kapena mphete yakunja ndi chitsulo cholimba, (monga mpweya zitsulo, zitsulo zosapanga dzimbiri, zina dzimbiri zosagwira aloyi) mphete yolimbikitsa yakunja sikugwirizana ndi sing'anga yosindikiza, kotero sikuyenera kukana dzimbiri sing'anga, choncho nthawi zambiri amapangidwa ndi carbon steel material.The kunja kulimbikitsa mphete akhoza komanso kukhala lonse ndi zinthu zosindikiza, monga zitsulo toothed gasket ndi wave toothed gulu gasket.

2, polytetrafluoroethylene gasket

Mu zotheka ntchito zosiyanasiyana kutentha (-180 — 250 ℃) sangathe dzimbiri ndi mankhwala ndi zosungunulira, komanso akhoza kuchita odana electrochemical dzimbiri chitoliro kutchinjiriza chitoliro gasket. flange ndi flange ndi madzi mzere, osati kwa flange lonse.Nthawi zambiri amagwiritsidwa ntchito polimbana ndi dzimbiri.Kuti akwaniritse kusindikiza kwabwino, gasket imatha kukutidwa ndi phala la teflon.Koma kutayikira kukana, psinjika kukana kuposa PTFE lathyathyathya gasket ndi wapamwamba, angagwiritsidwe ntchito lonse flange.The osachepera preload enieni kuthamanga y wa chisindikizo ndi 11.77-19.6MPa, ntchito kutentha ndi 200 ℃, kuthamanga ndi za 0.98MPa .

Zitsanzo zama tag:

Mtundu wa gasket: wokhala ndi mphete yamkati ndikuyika ngati mphete;Mphete ndi chitsulo chochepa cha carbon, lamba wachitsulo ndi OCr18Ni9;M'mimba mwake mwadzina 150mm;Kupanikizika mwadzina 4.OMpa(40bar);Gasket kukula muyezo GB/T4622.2-2003;

Zolemba ndi: D 1222-DN150-PN40 GB/T4622.2

Mtundu wa gasket: mtundu woyambira;Zida za gasket: lamba wachitsulo ndi 0Cr18Ni9, Lamba wodzaza ndi graphite wosinthika;M'mimba mwake mwadzina 150mm;Kupanikizika mwadzina 4.OMpa(40bar);Gasket kukula muyezo GB/T4622.2-2003;
