ʻO ka PTFE Lining Pneumatic Operation Wafer Butterfly Valve Features
ʻO ka valve butterfly PTFE-lining he kūpono ia no nā wahi kūikawā e like me ka waikawa ikaika, alkali ikaika corrosive environment, petroleum, kemika, meaʻai, etc.
Hiki ke hoʻokō ʻia ka hana kūʻē anti-corrosion ke hoʻopaʻa ʻia ʻo PTFE ma waena o ke kino valve a me ka disc valve.
Na Hiʻona Sila
ʻO ka hoʻopaʻa ʻana i ke kumu o ka valve, ʻaʻole wale ka hoʻopaʻa ʻana ma waena o ka diski luna a me lalo a me ka noho (ke sila mua), akā hoʻohana pū kekahi i ka hoʻolālā preload disc spring a me ka pā valve inlaid O-ring seal (sila ʻelua).Ma o ke kaomi axial valve butterfly, ʻoi aku ka paʻa o ka pā valve a me ka hoʻopaʻa ʻana i ka noho o ka valve, i ka manawa like ke kaomi ʻana i ka lua O-ring i ke kolu o ka sila ʻana.
Loaʻa ka bearing self-lubricating i ke kūlana hole stem valve, kahi e hana ai i ke kūlana axial a me ka hoʻololi paʻa.
No ka PTFE-lining butterfly valve, hiki i ka mānoanoa o ka papa ke hiki i 3 〜5MM hiki ke kū i ka 12 〜20KV EDM (caliber a me nā mea ʻē aʻe), nā mea koho PTFE / FEP / PFA a pēlā aku.
