¢ Ukwethulwa kwe-gasket
I-Polytetrafluoroethylene (PTFE) packing gasket iwuhlobo lwecushion eyinhlanganisela engeyona eyensimbi, ngokuvamile eyakhiwa izingxenye ezimbili: isembozo nesishuthekayo. Umsebenzi oyinhloko wemvilophu i-anti-corrosion, ngokuvamile eyenziwa nge-polytetrafluoroethylene. I-insert (filler) yinto engeyona eyensimbi enezinsimbi noma ngaphandle kwayo, ngokuvamile okwenziwa ngeshidi lerabha le-asbestos.
I-Polytetrafluoroethylene (PTFE) yokupakisha i-gasket ifaneleka ngokuyinhloko indiza egcwele kanye nokuxhumeka kwepayipi lensimbi lobuso obuphakanyisiwe. Ilungele i-corrod medium ene-pressure ye-PN engu-0.6 ~ 5.0mpa kanye nezinga lokushisa elisebenzayo lika-0 ~ 150 ¡æ noma eliphakathi nendawo elinezidingo zokuhlanzeka okuphezulu.
¢ Ú Uhlobo lwe-gasket
I-Polytetrafluoroethylene (PTFE) gasket ye-pipe flange ingahlukaniswa ngezinhlobo ezintathu ngokuya nezindlela zokukhiqiza: uhlobo lokusika (s uhlobo), uhlobo lwemishini (uhlobo lwe-M) kanye nohlobo lokugoqa (uhlobo F).
Ku-gasket yokupakisha eyenziwe ngomshini, ububanzi bangaphakathi bongqimba bokupakisha bungakwazi ukuhambisana nobubanzi bangaphakathi be-flange, ukuze kuvinjwe i-eddy current yoketshezi ku-flange. Ngokuqondene ne-gasket yokupakisha egoqiwe, yenziwe ngefilimu ye-polytetrafluoroethylene (PTFE) engu-0.4-0.8 mm obukhulu. Ngemuva kokuvalwa kokushisa, iziphetho zombili ze-gasket zigoqwe ngaphandle kwe-annular core material ngesimo sika-U. Kulula ukwenza futhi ifanele ukuvala uphawu lwe-flange enkulu.
