Valavu ya Gulugufe Yokhala ndi Mphira yokhala ndi Chisindikizo cha EPDM: Chidule Chathunthu

**Ma valve a gulugufe okhala ndi rabara okhala ndi zisindikizo za EPDM: chidule chathunthu**

Ma valve a gulugufendi zinthu zofunika kwambiri pa ntchito zosiyanasiyana zamafakitale, zomwe zimathandiza kuti pakhale njira yoyendetsera bwino kayendedwe ka madzi m'mapaipi. Pakati pa mitundu yosiyanasiyana yamavavu a gulugufeMa valve a gulugufe okhala ndi rabara amaonekera bwino chifukwa cha kapangidwe kawo kapadera komanso magwiridwe antchito awo. Chimodzi mwa zinthu zofunika kwambiri pagululi ndikugwiritsa ntchito zisindikizo za EPDM (ethylene propylene diene monomer), zomwe zimapangitsa kuti valavuyo izigwira ntchito bwino komanso kuti ikhale yolimba.

Zisindikizo za EPDM zimadziwika kuti zimalimbana bwino ndi kutentha, ozone ndi nyengo, zomwe zimapangitsa kuti zikhale zoyenera kugwiritsidwa ntchito pofunikira kutsekedwa kodalirika m'malo ovuta. Zikaphatikizidwa mu ma valve a gulugufe okhala ndi rabara, zisindikizo za EPDM zimatseka bwino, kuchepetsa chiopsezo cha kutuluka kwa madzi ndikuwonetsetsa kuti kuyenda kwa madzi kukuyenda bwino. Izi ndizofunikira kwambiri m'mafakitale monga kuyeretsa madzi, kukonza mankhwala ndi machitidwe a HVAC, komwe kusunga umphumphu wa makina ndikofunikira.

Ma valve a gulugufe okhala ndi mphiraNdi zisindikizo za EPDM, zinthu za EPDM zimatha kupirira kutentha kwakukulu, nthawi zambiri -40°C mpaka 120°C, zomwe zimapangitsa kuti zikhale zoyenera kugwiritsidwa ntchito kutentha ndi kuzizira. Chachiwiri, kusinthasintha kwa mpando wa rabara kumalola kuti ugwire bwino ntchito, kuchepetsa mphamvu yofunikira kuti mutsegule ndi kutseka valavu. Izi sizimangowonjezera zomwe ogwiritsa ntchito amagwiritsa ntchito, komanso zimawonjezera moyo wa valavu.

Kuphatikiza apo, kapangidwe kake kopepuka ka valavu ya gulugufe, pamodzi ndi chisindikizo chake champhamvu cha EPDM, zimathandiza kuti kuyika ndi kukonza zikhale zosavuta. Ogwiritsa ntchito amatha kusintha chisindikizocho mwachangu popanda kugwiritsa ntchito zida zapadera, zomwe zimapangitsa kuti nthawi yogwira ntchito ikhale yochepa.

Pomaliza, mavavu a gulugufe okhala ndi mphira okhala ndi zisindikizo za EPDM akuyimira luso lalikulu muukadaulo wowongolera kuyenda kwa madzi. Kulimba kwawo, kukana zinthu zachilengedwe komanso kusamalitsa kosavuta kumapangitsa kuti akhale chisankho chabwino kwambiri pamafakitale osiyanasiyana. Pamene makampani akupitilizabe kusintha, kufunikira kwa mayankho odalirika komanso ogwira ntchito bwino a mavavu mosakayikira kudzakula, motero kuphatikiza ntchito ya mavavu a gulugufe otsekedwa a EPDM muukadaulo wamakono.
