I-Valve Yeluvivane Lehleti Ngerabha Lenekuvala Kwe-EPDM: Umbiko Lophelele

**Emavalvu e-butterfly lahleti ngerabha lanetimphawu te-EPDM: umbono lophelele**

Emavalvu evivanetincenye letibalulekile etincenyeni letehlukahlukene tetimboni, kuniketa kulawula kugeleza lokuphumelelako emaphayiphini. Emkhatsini wetinhlobo letehlukene te .emavalvu evivane, emavalvu e-butterfly lahleti ngerabha agcamile ngenca yekwakhiwa kwawo lokuhlukile kanye nekusebenta kwawo. Lokunye lokubaluleke kakhulu kulesigaba kwemukelwa kwetimphawu te-EPDM (ethylene propylene diene monomer), lokwenta ncono kusebenta kanye nekucina kwevalve.

Timphawu te EPDM tatiwa ngekumelana kwato lokuhle kakhulu nekushisa, i-ozone kanye nesimo selitulu, kwenta kutsi tilungele kusetjentiswa lokudzinga kuvalwa lokutsembekile etimeni letilukhuni. Uma kuhlanganiswa kumavalvu e-butterfly lahleti ngerabha, timphawu te-EPDM tiniketa kuvalwa lokucinile, kunciphisa ingoti yekuvuta kanye nekucinisekisa kulawula kugeleta lokukahle. Loku kubaluleke kakhulu etimbonini letifana nekuhlanta emanti, kucubungula emakhemikhali kanye netinhlelo te-HVAC, lapho khona kugcina bucotfo beluhlelo kubaluleke kakhulu.

Emavalvu evivane lahleti ngerabhange EPDM timphawu baniketa tinzuzo letinyenti. Kwekucala, lentfo ye EPDM ingamelana nelizinga lelikhulu lekushisa, ngalokuvamile -40°C kuya ku 120°C, kwenta kutsi ilungele kokubili kusetjentiswa lokushisako nalokubandzako. Kwesibili, kugucugucuka kwesihlalo serabha kuvumela kusebenta kahle, kunciphisa i-torque ledzingekako yekuvula nekuvala i-valve. Lesi sici akugcini nje ngekutfutfukisa umuva wemsebentisi, kepha futsi kwandzisa impilo yemhlangano wevalve.

Ngetulu kwaloko, umklamo we-valve we-butterfly lolula, lohambisana nekuvala kwayo lokucinile kwe-EPDM, kuvumela kufakwa nekunakekelwa lokulula. Basebentisi bangasheshe bashintje luphawu ngaphandle kwesidzingo semathuluzi lakhetsekile, kucinisekisa sikhatsi lesincane sekuphumula.

Ekuphetseni, emavalvu e-butterfly lahleti ngerabha lanetimphawu te-EPDM amelela kusungulwa lokubalulekile ebuchwephesheni bekulawula kugeleza. Kucina kwawo, kumelana netintfo temvelo kanye nekunakekelwa kalula kwenta kutsi kube kukhetsa lokusetulu kwetintfo letiningi letisetjentiswako etimbonini. Njengobe lemboni ichubeka nekutfutfuka, kufuna tisombululo temavalvu letitsembekile naletisebenta kahle akungabateki kutsi kutawukhula, ngaleyo ndlela kuhlanganiswe indzima yemavalvu e-butterfly lavalwe yi-EPDM ebunjiniyela besimanje.
