Hobaneng ha Butterfly Valve e Tiisa Li-Heroes tse sa Bonoeng tsa Litsamaiso tsa Sejoale-joale tsa Taolo ea Mekelikeli?

1. Litiiso tsa Butterfly Valve ke Eng? Sebopeho sa Motheo le Mefuta ea Bohlokoa

Li-valve tsa li-butterfly (tse boetse li bitsoalitiiso tsa setulokapaliner liner) ke likarolo tsa bohlokoa tse netefatsang ts'ebetso ea ho lutla ha li-valve tsa serurubele. Ho fapana le li-gaskets tsa setso, litiiso tsena li kopanya ka ho toba 'meleng oa valve, ho fana ka tiiso e matla pakeng tsa disc le matlo.

• Mefuta e Tloaelehileng:
• Litiiso tsa EPDM: Molemo ka ho fetisisa bakeng sa mekhoa ea metsi (-20 ° C ho ea ho 120 ° C).
• Litiiso tsa FKM (Viton®).: E loketse lik'hemik'hale le mocheso o phahameng (ho fihlela ho 200 ° C).
• PTFE Litiiso: E sebelisoa mecheng ea litaba e hloekileng haholo kapa e senyang (mohlala, ho sebetsa ka meriana).
• Litiiso Tse Matlafalitsoeng ka Tšepe: Bakeng sa lisebelisoa tsa mouoane oa khatello e phahameng (ANSI Class 600+).

2. Litiiso tsa Butterfly Valve li sebelisoa Hokae? Likopo tse holimo tsa indasteri

Li-valve tsa li-butterfly li bohlokoa liindastering mooho koala ka potlako, torque e tlase, le khanyetso ea lik'hemik'haletaba:

• Phekolo ea Metsi le Litšila: Litiiso tsa EPDM li laola ka lebaka la ho hanyetsa ozone.
• Oli le Khase: Litiiso tsa FKM li thibela ho lutla ha liphaephe tsa oli tse tala (API 609 e lumellana).
• Lijo & Seno: Litiiso tsa PTFE tsa FDA-grade li netefatsa bohloeki ts'ebetsong ea lebese.
• Sistimi ea HVAC: Litiiso tsa Nitrile li tšoara lihatsetsi ntle le ho ruruha.

3. Litiiso tsa Butterfly Valve li Sebetsa Joang? Saense ka Mora ho Zero-Leakage

• Khatello ea Elastomer: Setiiso se senyeha hanyenyane ha valve e koala, e etsa hore ho be le mokoallo o thata.
• Tiiso e Thusang ke Khatello: Ka likhatello tse phahameng (mohlala, 150 PSI +), khatello ea tsamaiso e sutumelletsa tiiso ka thata khahlanong le disc.
• Ho Tiisa ka Bidirectional: Meralo e tsoetseng pele (joalo kalitiiso tse habeli) thibela ho lutla ka mahlakoreng a mabeli a phallo.

• Li-valve tsa Flush pele li kenya lits'ebetsong tse litšila.
• Boloka litiiso tse setseng ka har'aLijana tse sirelelitsoeng ka UV.

❌U se ke ua etsa joalo:

• Ho feta tekanyo ea mocheso (e baka ho thatafala ha tiiso).
• Sebelisa petroleum grease ho EPDM (kotsi ea ho ruruha).
• Iphapanyetseho tsamaisana le disc-to-sealnakong ea ho kenya.
