Isihlalo Esimnyama/Esiluhlaza PTFE/ FPM +EPDM Isihlalo Sevalve Yerabha Yesihlalo Sovemvane
I-PTFE + EPDM izihlalo ze-valve yenjoloba ehlanganisiwe ekhiqizwa yi-SML zisetshenziswa kakhulu kwendwangu, isiteshi samandla, i-petrochemical, ukushisa kanye nesiqandisi, imithi, ukwakha umkhumbi, i-metallurgy, imboni yokukhanya, ukuvikelwa kwemvelo kanye neminye imikhakha.
Ukusebenza komkhiqizo: ukumelana nokushisa okuphezulu, ukumelana okuhle kwe-asidi ne-alkali nokumelana nowoyela; enokuqina okuhle kwe-rebound, eqinile futhi ehlala isikhathi eside ngaphandle kokuvuza.
I-PTFE+EPDM
Ulayini we-Teflon (PTFE) umbondela i-EPDM ehlanganiswe neringi ye-phenolic eqinile kupherimitha yesihlalo esingaphandle. I-PTFE inweba phezu kobuso besihlalo kanye nobubanzi be-flange seal yangaphandle, imboze ngokuphelele ungqimba lwe-EPDM elastomer lwesihlalo, oluhlinzeka ngokuqina kokuvala iziqu ze-valve kanye nediski evaliwe.
Ibanga lokushisa: -10°C ukuya ku-150°C.
I-PTFE (i-Polytetrafluoroethylene)
I-PTFE (i-Teflon) iyi-polymer esekelwe ku-fluorocarbon futhi ngokuvamile ingevani namakhemikhali kakhulu kuwo wonke amapulasitiki, kuyilapho igcina izici ezinhle kakhulu zokushiswa kokushisa nezikagesi. I-PTFE futhi ine-coefficient ephansi yokungqubuzana ngakho ilungele izinhlelo zokusebenza eziningi zetorque ephansi.
Lokhu okuqukethwe akukona-angcolisi futhi kwamukelwe yi-FDA ngezicelo zokudla. Nakuba izakhiwo zemishini ze-PTFE ziphansi, uma ziqhathaniswa namanye amapulasitiki akhiwe, izakhiwo zawo zihlala ziwusizo phezu kwezinga lokushisa elibanzi.
Ibanga lokushisa: -38°C ukuya +230°C.
Umbala: omhlophe
I-torque adder: 0%

Izindandatho zethu ezihlanganisiwe ze-EPDM+PTFE ziyisibonelo sokuqanjwa kwesayensi yezinto ezibonakalayo, ehlanganisa ukuqina nokuguquguquka kwerabha ye-EPDM nokungangeni kwamakhemikhali nokumelana nezinga lokushisa kwe-PTFE. Lokhu kwakheka okuyingxubevange kuqinisekisa ukusebenza okuhle ezinhlelweni ezibandakanya amanzi, uwoyela, igesi, uwoyela oyisisekelo, kanye nama-asidi anolaka. Kungakhathaliseki ukuthi usezimbonini ze-petrochemical, ezemithi, zasolwandle, noma ezivikela imvelo, izixazululo zethu zokuvala ziklanyelwe ukuhlangabezana futhi zeqe izimfuneko eziqinile zezinga lokushisa eliphezulu kanye nezimo ezigqwalile. I-DN50 kuya ku-DN600, iwenza afaneleke ngokuphelele ezinhlotsheni ezahlukahlukene zamavalvu kufaka phakathi uhlobo lwe-wafer oluphakathi nendawo oluthambile oluvala uphawu lwevemvane amavalvu kanye ama-valve e-butterfly we-pneumatic wafer. Izici zedizayini eziyingqayizivele ezifana ne-wafer, iziphetho ze-flange, kanye nohlobo lwe-lug shaft ephindwe kabili ngaphandle kwephini linikeza kalula ukufaka nokuqinisekisa ukulingana okuvikelekile, okunciphisa ubungozi bokuvuza. Ukuzibophezela kwethu kukhwalithi nokuqamba okusha kubonakala kuyo yonke i-EPDM+PTFE ehlanganisiwe yokuvalwa kwamavalvu evamvane iringi esiyikhiqizayo, okwenza i-Sansheng Fluorine Plastics uye kwakho-umthombo wezixazululo ezithembekile zokuvala ama-valve.
