I-Rubber Seated Butterfly Valve enokuvalwa kwe-EPDM: Uhlolojikelele Oluphelele

**Amavalvu ovemvane ahlezi enjoloba anezigxivizo ze-EPDM: ukubuka konke**

Ama-valve e-Butterflyziyizingxenye ezibalulekile ezinhlelweni ezihlukene zezimboni, ezihlinzeka ngokulawula okusebenzayo kokugeleza kwamapayipi. Phakathi kwezinhlobo ezahlukene zeizivalo uvemvane, ama-valve uvemvane ahlezi enjoloba agqama ngenxa yomklamo wawo oyingqayizivele nokusebenza kwawo. Enye yentuthuko ebaluleke kakhulu kulesi sigaba ukwamukelwa kwezimpawu ze-EPDM (ethylene propylene diene monomer), okuthuthukisa ukusebenza nokuqina kwe-valve.

Izigxivizo ze-EPDM zaziwa ngokumelana kwazo okuhle kakhulu nokushisa, i-ozone kanye nesimo sezulu, okuzenza zilungele izinhlelo zokusebenza ezidinga ukuvalwa okuthembekile ezimeni ezinzima. Uma ihlanganiswe kumavalvu ovemvane ahlezi enjoloba, izigxivizo ze-EPDM zinikeza ukuvala okuqinile, okunciphisa ubungozi bokuvuza kanye nokuqinisekisa ukulawulwa kokugeleza okuphelele. Lokhu kubaluleke kakhulu ezimbonini ezinjengokuhlanza amanzi, ukucubungula amakhemikhali kanye nezinhlelo ze-HVAC, lapho ukugcinwa kobuqotho besistimu kubalulekile.

Amavalvu ovemvane ahlezi erabhangezimpawu ze-EPDM zinikeza izinzuzo ezimbalwa. Okokuqala, impahla ye-EPDM ingamelana nezinga lokushisa elibanzi, ngokuvamile -40°C kuya ku-120°C, ikwenze ifaneleke kokubili izicelo ezishisayo nezibandayo. Okwesibili, ukuguquguquka kwesihlalo senjoloba kuvumela ukusebenza kahle, ukunciphisa i-torque edingekayo ukuze uvule futhi uvale i-valve. Lesi sici asigcini nje ngokuthuthukisa isipiliyoni somsebenzisi, kodwa futhi sandisa impilo yomhlangano we-valve.

Ngaphezu kwalokho, idizayini yevalve uvemvane engasindi, ehlanganiswe nophawu lwayo oluqinile lwe-EPDM, ivumela ukufakwa nokugcinwa kalula. Abasebenzisi bangashintsha ngokushesha uphawu ngaphandle kwesidingo samathuluzi akhethekile, baqinisekise ukuphumula okuncane.

Sengiphetha, ama-valve evemvane ahlezi enjoloba anezigxivizo ze-EPDM amelela ukusha okuphawulekayo kubuchwepheshe bokulawula ukugeleza. Ukuqina kwazo, ukumelana nezimo zemvelo kanye nokugcinwa kalula kwazo kuzenza zibe yisinqumo esiphezulu ezinhlobonhlobo zezicelo zezimboni. Njengoba imboni iqhubeka nokuvela, isidingo sezixazululo zama-valve ezinokwethenjelwa nezisebenza kahle ngokungangabazeki sizokhula, ngaleyo ndlela kuhlanganiswe indima yama-butterfly avaliwe e-EPDM kubunjiniyela besimanje.
