¢U Ukwaziswa kwegasket
I-Polytetrafluoroethylene (PTFE) yokupakisha i-gasket luhlobo lwe-cushion ye-non-metallic composite, eyenziwa ngokubanzi ngamacandelo amabini: isigqubuthelo kunye nokufakwa. Umsebenzi oyintloko wemvulophu yi-anti-corrosion, edla ngokuba yenziwe nge-polytetrafluoroethylene. I-insert (i-filler) yinto engeyiyo-metallic kunye okanye ngaphandle kokuqiniswa kwetsimbi, edla ngokwenziwa kwiphepha le-rubber ye-asbestos.
I-Polytetrafluoroethylene (PTFE) i-gasket yokupakisha ilungele ubukhulu becala inqwelomoya epheleleyo kunye noqhagamshelo lwentsimbi yombhobho wentsimbi. Ifanelekile kwi-corrosive medium kunye ne-nominal pressure PN ye-0.6 ~ 5.0mpa kunye nokushisa okusebenzayo kwe-0 ~ 150 ¡æ okanye ephakathi kunye neemfuno zokucoceka okuphezulu.
¢Ú Uhlobo lwegasket
I-Polytetrafluoroethylene (PTFE) gasket yeflange yombhobho inokwahlulwa ibe ziindidi ezintathu ngokweendlela zokuvelisa: uhlobo lokusika (s uhlobo), uhlobo lomatshini (uhlobo lwe-M) kunye nohlobo lokusonga (uhlobo F).
Kwi-gasket yokupakisha ngomatshini, ububanzi bangaphakathi bomgangatho wokupakisha bunokuhambelana nobubanzi obungaphakathi be-flange, ukwenzela ukuba kuthintelwe i-eddy current ye-fluid kwi-flange. Ngokuphathelele i-gasket yokupakisha esongiweyo, yenziwe ngefilimu ye-0.4-0.8 mm ye-polytetrafluoroethylene (PTFE) engqingqwa. Emva kokutywinwa kobushushu, zombini iziphelo ze-gasket zisongelwe ngaphandle kwezinto ezingundoqo ze-annular kwimilo engu-U. Kulula ukwenza kwaye ilungele ukutywinwa kweflange enkulu.
