Rubber Seated Butterfly Valve ni EPDM sigicogo: A lajɛlen

**Butterfly valves sigilen bɛ lastikuw kan ni EPDM sigilanw ye: jateminɛ bɛɛ lajɛlen**

Butterfly (butterfly) bɔgɔlanwye fɛn nafamaw ye izini baara suguya caman na, minnu bɛ jibɔ kɔlɔsili ɲuman di pibilikiw kɔnɔ. A suguya wɛrɛw cɛmabutterfly valvew (wuluwuluw)., butterfly valves sigilen bɛ lastikuw la, olu bɛ bɔ kɛnɛ kan k’a sababu kɛ u dilanni n’u baarakɛcogo ɲɔgɔn tɛ. Ɲɛtaa minnu nafa ka bon kosɛbɛ nin kulu in na, olu dɔ ye EPDM (éthylène propylène diène monomère) sigilanw tali ye, o min bɛ sumanmugu baarakɛcogo n’a muɲuli ɲɛ.

EPDM sigilanw dɔnna u ka se ka funteni, ozɔni ani waati cogoyaw kɛlɛ kosɛbɛ, o b’a to u ka ɲi kosɛbɛ baarakɛcogo la minnu bɛ sigili dafalen wajibiya cogo gɛlɛnw na. Ni u donna wuluwuluw kɔnɔ minnu sigilen don ni lastikuw ye, EPDM sigilanw bɛ da siri kosɛbɛ, o bɛ dɔ bɔ bɔgɔbɔli farati la ani ka jibɔ kɔlɔsili ɲuman sabati. O nafa ka bon kosɛbɛ iziniw na i n’a fɔ ji saniya, kemikɛli ani HVAC sigidaw, yɔrɔ minnu na sigida dafalen marali nafa ka bon kosɛbɛ.

Lastikuw sigilen bɛ butterfly valvesni EPDM sigilanw bɛ nafa caman di. A fɔlɔ, EPDM fɛn bɛ se ka funteni hakɛ caman muɲu, a ka c’a la -40°C fo 120°C, o b’a to a bɛ bɛn funteni ni nɛnɛ bɛɛ ma. Filanan, lastikuw sigilan bɛ se ka wuli ka bɔ a nɔ na, ​​o bɛ kɛ sababu ye ka baara kɛ ka ɲɛ, o bɛ dɔ bɔ girinya la min ka kan ka kɛ walasa ka da wuli ani ka da tugu. O kɛcogo in tɛ baarakɛlaw ka dɔnniya bonya dɔrɔn, nka a bɛ valve lajɛlen ka ɲɛnamaya janya fana.

Ka fara o kan, butterfly valve in dilanni nɔgɔyalen, n’o farala a ka EPDM sigilan barikama kan, o b’a to a sigili n’a ladonni ka nɔgɔn. Baarakɛlaw bɛ se ka sigilan wuli joona k’a sɔrɔ u mago tɛ baarakɛminɛn kɛrɛnkɛrɛnnenw na, o bɛ kɛ sababu ye ka baarakɛwaati dɔgɔya.

Kuncɛli la, wuluwulu sigilenw ni lastikuw ye minnu bɛ ni EPDM sigilanw ye, olu bɛ fɛn kuraba jira jibɔ kɔlɔsili fɛɛrɛ la. U muɲuli, u ka se ka sigida kow kɛlɛ ani u ladonni nɔgɔya b’u kɛ sugandili sanfɛla ye izini baara caman na.
