I-tape engeyona yensimbi
Izinto ezisetshenziswa ngokuvamile ezingezona ezensimbi, njenge-graphite eguquguqukayo (<600 ° C), i-polytetrafluoroethylene (-200~260 ° C), ibhodi eliyinhlanganisela yerabha eliqiniswe ngefiber.
Iribhoni Lensimbi
I-StrapShape: V, W, wavy, njllIzinto ezibonakalayo: 0.15 ~ 0.25 insimbi ye-carbon ephansi, insimbi engagqwali, ithusi namanye ama-alloys aphikisana nokugqwala, njll.Umsebenzi: lawula ukuqina kokucindezela kwe-gasket, ukuvala;Khulisa ukuqina okuphelele kwe-gasket.
Indandatho yangaphakathi
Isimiso: Iringi yangaphakathi ihlangene noketshezi, futhi impahla yayo kufanele imelane nokugqwala kwendawo yokuvala.
Izinto zokwakha: i-carbon steel, insimbi engagqwali, amanye ama-alloys angagqwali, njll.
Umsebenzi: Ukuvimbela igebe phakathi kwengxenye yokuvala kanye nesiqukathi noma i-flange yepayipi ukuze ugwemeLeli gebe liphazamisa ukugeleza koketshezi kanye nokuguguleka koketshezi okuwumphumela we-gasket.Lapho ingcindezi yoketshezi lwangaphakathi kanye nezinga lokushisa liphezulu, ukugqwala koketshezi lwangaphakathi kanye nokuhuzuka kushubile, uketshezi luyavinjelwa ukuba luhlale esikhaleni se-flange, ubukhulu be-gasket bukhulu noma ukusetshenziswa kwe-convex ne-concave flange nezinye izikhathi, iringi yangaphakathi. isethiwe.
Indandatho yendawo (indandatho yangaphandle)
Umsebenzi: ukuqinisa nokuma okulungile komzimba we-gasket, ukuvimbela ukuminyanisa okuqine kakhulu ekulahlekelweni amandla e-springback e-gasket futhi kuvimbele i-gasket ukuthi ingaxegi.Impahla: Indandatho yangaphandle eqinisayo noma into eyindandatho yangaphandle iyinsimbi eqinile, (njenge i-carbon steel, insimbi engagqwali, amanye ama-alloys aphikisana nokugqwala) indandatho yangaphandle yokuqinisa ayihlangene nendawo yokuvala, ngakho-ke ayidingeki ukumelana nokugqwala okuphakathi, ngakho-ke kuvame ukwakhiwa nge-carbon steel material.Indandatho yangaphandle yokuqinisa ingakwazi futhi ukumelana nokugqwala okuphakathi. zenziwe zibe ziphelele ngezinto zokuvala, njenge-metal toothed gasket kanye ne-wave toothed composite gasket.
2, i-polytetrafluoroethylene gasket
Ekusetshenzisweni okungenzeka kwebanga lokushisa (-180 — 250 ℃) akunakugqwala ngamakhemikhali nezinyibilikisi, kodwa futhi ingenza ipayipi lokugqwala elilwa ne-electrochemical corrosion gasket. i-flange ne-flange enomugqa wamanzi, hhayi i-flange ebanzi.Okuningi okusetshenziselwa izikhathi zokumelana nokugqwala.Ukuze kuzuzwe umphumela omuhle wokuvala, i-gasket ingambozwa nge-teflon paste.(2) I-Polytetrafluoroethylene izwa i-gasket: izakhiwo zayo zamakhemikhali ziyafana ne-polytetrafluoroethylene gasket flat.Kodwa ukumelana nokuvuza, ukumelana nokucindezela kune-PTFE flat gasket ephakeme, ingasetshenziselwa i-flange ebanzi.Ingcindezi encane yokulayisha kuqala y yophawu ingu-11.77-19.6MPa, izinga lokushisa lokusetshenziswa lingu-200 ℃, ingcindezi imayelana no-0.98MPa .
Izibonelo zamathegi:
Uhlobo lwe-gasket: ngendandatho yangaphakathi futhi isethwe njengohlobo lwendandatho;Indaba yendandatho iyinsimbi ephansi ye-carbon, impahla yebhande lensimbi i-OCr18Ni9;Ubukhulu obujwayelekile buyi-150mm;Ukucindezela okulinganiselwe 4.OMpa(40bar) ;Usayizi we-Gasket standard GB/T4622.2-2003;
Ibhalwe ukuthi: D 1222-DN150-PN40 GB/T4622.2
Uhlobo lwe-gasket: uhlobo oluyisisekelo;Impahla ye-Gasket: impahla yebhande lensimbi yi-0Cr18Ni9, Into yebhande lokugcwalisa i-graphite eguquguqukayo;Ubukhulu obujwayelekile buyi-150mm;Ukucindezela okulinganiselwe 4.OMpa(40bar) ;Usayizi we-Gasket standard GB/T4622.2-2003;
Imakwe ngokuthi: A 0220-DN150-PN40 GB/T4622.2
