Izinto ezintathu eziqhelekileyo ezisetyenziswayo zokutywina kwiivalvu ze-solenoid

1. I-NBR irabha yerabha
Ivalve ye-solenoid yenziwe nge-emulsion polymerization ye-butadiene kunye ne-acrylonitrile. Irabha yeNitrile iveliswa ikakhulu yi-polymerization ye-emulsion yobushushu obuphantsi. Inokumelana ne-oyile okugqwesileyo, ukumelana nokunxiba okuphezulu, ukumelana nobushushu okulungileyo, kunye nokuncamathela okuqinileyo. Ukungalungi kwayo kukunganyangeki kobushushu obuphantsi, ukunganyangeki kwe-ozone, iipropathi ezilambathayo zombane, kunye nokuqina okuncinci. Eyona njongo yevalve ye-solenoid: irabha ye-nitrile yesivalo se-solenoid isetyenziselwa ukwenza iimveliso ezichasene ne-oyile. Iivalvu ze-Solenoid ezinjengemibhobho enganyangekiyo kwioyile, iiteyiphu, iidiaphragm zerabha kunye neengxowa ezinkulu zeoyile ziqhele ukusetyenziselwa ukwenza iimveliso ezibunjiweyo ezikwaziyo ukumelana neoyile, ezinje nge-O-ring, izitywina zeoyile, kunye nesikhumba. Izitya, i-diaphragm, iivalvu, izivunguvungu, njl. njl. zikwasetyenziselwa ukwenza amaphepha erabha kunye namalungu anganxibi
2. I-EPDM EPDM (i-Ethylene-Propylene-Diene Monomer) i-solenoid valve Eyona nto iphambili kwi-EPDM kukumelana kwayo ne-oxidation, i-ozone kunye ne-corrosion. Kuba i-EPDM yeyosapho lwe-polyolefin, ineempawu ezibalaseleyo zokuqunjelwa. Kuzo zonke iirubbers, i-EPDM ine-gravity esezantsi. Isivingco se-solenoid sinokufunxa inani elikhulu lokugcwalisa kunye neoyile ngaphandle kokuchaphazela iimpawu zalo. Ke ngoko, iikhompawundi zerabha ezisezantsi zinokuveliswa. Solenoid valve ulwakhiwo lweemolekyuli kunye neempawu: I-EPDM yiterpolymer ye-ethylene, propylene kunye ne-diene-conjugated diene. I-Diolefins inesakhiwo esikhethekileyo. Inye kuphela yee-bond ezimbini ze-solenoid valve ezinokukhutshelwa, kwaye iibhondi eziphindiweyo ezingasetyenziswanga zisetyenziselwa ukunxibelelana. Enye into engafakwanga isaturated ayizukuba yeyona nto iphambili kuyo, kodwa iya kuba lityathanga lasecaleni kuphela. Ikhonkco ephambili ye-polymer ye-EPDM igcwele ngokupheleleyo. Eli nqaku levaloli ye-solenoid yenza i-EPDM inyamezele ubushushu, ukukhanya, ioksijini, ngakumbi i-ozone. I-EPDM ngokuqinisekileyo ayisiyi-polar, inokuchasana nezisombululo ze-polar kunye neekhemikhali, inokutsalwa kwamanzi okuphantsi, kwaye ineempawu ezifanelekileyo zokugquma. Iimpawu zevaloli zeSolenoid: â ‘ukuxinana okuphantsi kunye nokuzaliswa okuphezulu; â‘¡ ukuxhathisa ukwaluphala; â ‘resistance umhlwa; â ‘£ ukumelana nomphunga wamanzi; ⑤ ukumelana nobushushu bamanzi; â ‘performance ukusebenza kombane; ⑦ ukuthamba; ⑧ ukubambelela.
3. VITON ifluorine ngerabha (FKM)
Irabha ene-fluorine kwimolekyuli yevaluva ye-solenoid ineentlobo ezahlukeneyo ngokuxhomekeke kumxholo we-fluorine, okt ulwakhiwo lwe-monomer; irabha yefluorine yethambo le-solenoid valve hexafluoride ilunge ngakumbi kune-silicone yerabha kukumelana neqondo lobushushu eliphezulu, ukumelana kwemichiza, kunye nevaloli yesolenoid iyamelana neeoyile ezininzi kunye nezinto zokunyibilikisa (ngaphandle kweetoni kunye neesters), ukumelana nemozulu, ukumelana neozone kulungile, kodwa kuyabanda ukuxhathisa kuyinto embi; Izivalo ze-solenoid ngokubanzi zisetyenziswa ngokubanzi kwiimoto, izithuthuthu, i-B kunye nezinye iimveliso, kunye namatywina kwizityalo zemichiza. Uluhlu lobushushu olusebenzayo -20 ° C. ～260â „ƒ, uhlobo olunobushushu obusezantsi obunokusetyenziswa xa kusetyenziswa iimfuno ezinobushushu obuphantsi, ezinokusetyenziswa kwi - 40â„ ƒ, kodwa ixabiso liphezulu.
