Pali mitundu yambiri yavalavu ya butterfly discmolingana ndi kagwiritsidwe ntchito ka ma valve agulugufe, miyeso yodziwika bwino ya agulugufe m'matangadza amachokera ku DN50-DN600, kotero tiwonetsa ma disc a valve malinga ndi makulidwe omwe amagwiritsidwa ntchito nthawi zonse.
1.Nayiloni Coated Valve Disc
Kupopera mbewu kwa nayiloni ndiukadaulo wamba wopaka pamwamba womwe umapopera tinthu ta nayiloni mumadzimadzi pamwamba pa gawo lapansi ndikupanga filimu yolimba komanso yolimba ya nayiloni ikakhazikika.Kupaka utoto wa nayiloni kuli ndi ntchito zambiri komanso mawonekedwe ogwiritsira ntchito, nazi zina mwazogwiritsa ntchito nthawi zambiri:
- Chitetezo choletsa dzimbiri: Kupaka kwa nayiloni kumatha kugwiritsidwa ntchito ngati chitetezo chapamwamba chachitsulo.Nayiloni ili ndi zinthu zabwino zotsutsana ndi dzimbiri, imatha kudzipatula chitsulo ndi sing'anga yotuluka kunja, kutalikitsa moyo wa valavu.
- Chepetsani kukangana: Nayiloni ili ndi mawonekedwe abwinoko ochepetsa mikangano, imatha kuchepetsa kukangana pakati pa mpando wa valve ndi disc.
- Kukana kuvala: Nayiloni imakhala ndi ntchito yabwino yosamva kuvala, imatha kuchepetsa kukanda kwa disc.
2.PTFE Lining Valve Disc
- Non-yomata: Pamwamba pa PTFE chimbale kwambiri poterera ndi sanali zomata, akhoza modabwitsa kuchepetsa yomata kwa sing'anga zopinga.
- Kukana dzimbiri: PTFE ili ndi ntchito yabwino yotsutsa-zikuwononga, imatchedwa Mfumu ya pulasitiki chifukwa cha zinthu zodabwitsa zotsutsana ndi dzimbiri, imatha kugonjetsedwa ndi asidi ambiri amphamvu ndi alkali media.
- Chemical inertness: PTFE ndi inertness zambiri za mankhwala.Ikhoza kukana dzimbiri la mankhwala ambiri.
- Kuvala zosagwira: Ngakhale PTFE ndi zinthu zofewa, koma zimakhala ndi ntchito yabwino yosamva kuyerekeza ndi pulasitiki ina ngakhale chitsulo.Chimbale chokhala ndi PTFE pamwamba chimakhala ndi nthawi yayitali chifukwa cha mawonekedwe ake.
3.Aluminium Bronze Valve Disc
Aluminium bronze ndi aloyi yamkuwa yomwe nthawi zambiri imakhala ndi aluminium, mkuwa ndi zinthu zina zophatikizika monga manganese, chitsulo ndi zinki.Ili ndi zabwino zambiri zomwe zimapangitsa kuti zigwiritsidwe ntchito mosiyanasiyana.
- Kukana kwa dzimbiri: Mkuwa wa aluminiyamu umalimbana bwino ndi dzimbiri, makamaka m'malo amadzi am'nyanja ndi amchere.Izi zimapangitsa kukhala chinthu chomwe chimagwiritsidwa ntchito kwambiri pamakina apanyanja ndi akunyanja monga ma propellers, ma valve ndi mapaipi.
4.Nickel Plate Butterfly Valve Disc
- Makhalidwe odana ndi dzimbiri: Mbale ya Nickel imatha kuteteza pamwamba pa chimbale chachitsulo cha ductile kuti chisawonongeke ndi makina ogwiritsira ntchito.
- Kuuma: Ndi mbale ya nickel, pamwamba pa DI disc imatha kukhala yolimba kuposa kale.Itha kuthandizira kukana kwa disc kuchokera ku zopinga zapakatikati.
5.Rubber Lining Valve Disc
- Kusindikiza kwabwino: Disiki yokhala ndi mphira ya rabara idzakhala ndi ntchito yabwino kwambiri yosindikiza poyerekeza ndi chitsulo chachitsulo, ipereka mawonekedwe odalirika osindikiza.Imathandiza valavu kuteteza kutayikira.
6.Chimbale cha Butterfly Valve Chokwera Kwambiri
- Kupanga kwapadera kwa disc yothamanga kwambiri kumapereka magwiridwe antchito abwino kwambiri.Malinga ndi shafe yake yapadera komanso miyeso yolondola, imachepetsa kukana ndi kutsika kwapa media ogwira ntchito, kukwaniritsa kuthamanga kwambiri.
