PTFE, RPTFE, PEEK, DEVLON / NYLON, PPL ukurikije igitutu gitandukanye, ingano n'imiterere y'akazi.
Ibikoresho bisanzwe kumupira wa valve byoroshye gufunga ibikoresho bizaba
azaba BUNA-N, PTFE, RPTFE, VITON, TFM, nibindi
Kurondora ibintu bike byingenzi biranga:
BUNA-N (HYCAR cyangwa Nitrile)- Ubushyuhe ni -18 kugeza 100 ℃ ntarengwa.Buna-N ni polymer rusange-ifite intego nziza yo kurwanya amavuta, amazi, ibishishwa hamwe namazi ya hydraulic.Irerekana kandi kwikuramo neza, kurwanya abrasion, nimbaraga zikaze.Iyi ngingo ikora neza cyane mubice bitunganyirizwamo ibikoresho fatizo bya paraffin, aside irike, amavuta, alcool cyangwa glycerine, kubera ko bitagize ingaruka rwose.Ntigomba gukoreshwa hafi yumuti mwinshi (acetone, ketone), hydrocarbone ya chlorine, ozone cyangwa hydrocarbone ya nitro.Hycar ni umukara mu ibara kandi ntigomba gukoreshwa aho amabara adashobora kwihanganira.Bifatwa nkuwasimbuwe na neoprene.Itandukaniro nyamukuru ni: Buna-N ifite ubushyuhe buri hejuru;neoprene irwanya amavuta.
EPDM- Igipimo cy'ubushyuhe kiva kuri -29 ℃ kugeza 120 ℃.EPDM ni polyester elastomer ikozwe muri Ethylene-propylene diene monomer.EPDM ifite abrasion nziza kandi irwanya amarira kandi itanga imiti irwanya aside irike na alkaline.Irashobora kwibasirwa namavuta kandi ntabwo isabwa kubisabwa birimo amavuta ya peteroli, acide ikomeye, cyangwa alkaline ikomeye.EPDM ntigomba gukoreshwa kumurongo wikirere ucometse.Ifite ibihe byiza bidasanzwe gusaza no kurwanya ozone..Nibyiza rwose kuri ketone na alcool.
PTFE (TFE ya Teflon)- PTFE niyo irwanya imiti ya plastiki zose.Ifite kandi ibikoresho byiza byumuriro nubushyuhe bwamashanyarazi.Imikorere ya mashini ya PTFE iri hasi ugereranije nibindi bikoresho bya plastiki yubuhanga, ariko imitungo yayo iguma kurwego rwingirakamaro hejuru yubushyuhe bukabije (-100 ℃ kugeza 200 ℃, bitewe nibirango nibisabwa).
RTFE (TFE ishimangiwe/ RPTFE)- Ubushyuhe busanzwe ni -60 ℃ kugeza 232 ℃.RPTFE / RTFE yiyongereyeho ijanisha ryatoranijwe ryuzuza fibre ibirahure kugirango byongere imbaraga no kurwanya imyambarire idahwitse, imbeho ikonje, hamwe no kwinjira mubyicaro bibumbabumbwe. Gukomeza kwemerera gukoreshwa kumuvuduko mwinshi nubushyuhe burenze TFE ituzuye.RTFE ntigomba gukoreshwa mubisabwa byibasira ikirahure, nka hydrofluoric aside na caustique ikomeye.
CARBON YUZUYE TFE- Ubushyuhe ni -50 ℃ kugeza 260 ℃.Carbone yuzuye TFE nikintu cyiza cyicaro cyogukoresha amavuta kimwe nubushyuhe bwo hejuru bushingiye kumavuta yubushyuhe.Abuzuza harimo na grafite bashoboza iki cyicaro kugira ubuzima bwiza bwizunguruka kuruta izindi ntebe za TFE zuzuye cyangwa zishimangiwe.Kurwanya imiti bingana nizindi ntebe za TFE.
TFM1600-TFM1600 ni verisiyo yahinduwe ya PTFE igumana imiterere idasanzwe ya chimique nubushyuhe bwa PTFE, ariko ikagira ubukonje buke bwo gushonga cyane.Ibisubizo bigabanya ubukonje bwimitsi ikonje, ibyinjira nibidafite agaciro. Ibibanza biroroshye kandi bigabanya torque.Inyigisho serivisi ya TFM1600 ni -200 ℃ kugeza 260 ℃.
TFM1600 + 20% GF-TFM1600 + 20% GF ni fibre yikirahure ya verisiyo ya TFM1600.Bisa na RTFE, ariko hamwe ninyungu za TFM1600, verisiyo yuzuye ibirahuri itanga imbaraga zo kurwanya abrasion kandi ikanoza ituze kumuvuduko mwinshi.
TFM4215- TFM4215 ni intore ishushanya karubone yuzuye ibikoresho bya TFM. Carbone yongeyeho itezimbere ituze ryumuvuduko mwinshi hamwe nubushyuhe.
VITON (Fluorocarbon, FKM, cyangwa FPM)- Igipimo cy'ubushyuhe kiva kuri 29 ℃ kugeza 149 ℃.Fluorocarbon elastomer isanzwe ihujwe nubwinshi bwimiti.Kubera ubwo buryo bwinshi bwo guhuza imiti buringaniye hamwe nubushyuhe butandukanye, fluorocarbon elastomer imaze kwemerwa cyane nkigikoresho cyo kubaka icyicaro cy irembo ryicyuma. .Nibyiza cyane muri serivisi ya hydrocarubone.Ibara ni imvi (umukara) cyangwa umutuku kandi irashobora gukoreshwa kumurongo wimpapuro zumye.Fluorocarubone (VITON) ntabwo ikwiranye na serivise zamazi cyangwa amazi ashyushye, nyamara, muburyo bwa o-ring irashobora kwemerwa kumirongo ya hydrocarubone ivanze namazi ashyushye bitewe ku bwoko / ikirango.Kubikoresho byicaro FKM irashobora gutanga imbaraga nyinshi kubushakashatsi bwamazi ashyushye.
PEEK-Polyetheretherketone-yumuvuduko mwinshi igice cya-elastomer elastomer.Bikwiranye numuvuduko mwinshi na serivisi yubushyuhe.Iratanga kandi imbaraga zo kurwanya ruswa. Igipimo cy'ubushyuhe -56,6 ℃ kugeza 288 ℃.
DELRIN / POM-Icyicaro cyihariye cya Delrin gitangwa kumuvuduko mwinshi hamwe na serivise yubushyuhe bwo hasi.Bishobora gukoreshwa mukirere cyumuvuduko mwinshi, peteroli nibindi bitangazamakuru bya gaze ariko ntibikwiranye na okiside ikomeye. Igipimo cyubushyuhe-50 ℃ kugeza 100 ℃.
NYLON / DEVLON-Nylon (polyamide) intebe zitangwa kumuvuduko mwinshi hamwe na serivisi yubushyuhe bwo hasi.Birashobora gukoreshwa mubushyuhe bwo hejuru, peteroli nibindi bitangazamakuru bya gaze ariko ntibikwiranye na okiside ikomeye.Ubushyuhe -100 ℃ kugeza 150 ℃.Devlon ifite ibiranga igihe kirekire cyo kwinjiza amazi yo hepfo, kurwanya umuvuduko ukabije no kutagira umuriro mwiza.Devlon ikoreshwa cyane mumiyoboro ya peteroli na gaze karemano mumahanga ya trunnion ball valve class 600 ~ 1500lb.
