He kiʻekiʻe loa ke kūpaʻa kemika o ka PTFE a hiki ke pale aku i ka pala mai ka hapa nui o nā mea waikawa a me ka alkali, no laila kūpono ka noho PTFE a me ka disc i hoʻopaʻa ʻia me ka PTFE no nā ʻōnaehana paipu me nā mea ʻino.
Loaʻa i ka PTFE butterfly valve ke kūpaʻa maikaʻi loa i ka wela a me ke anu a hiki ke mālama i ka hana paʻa ma lalo o nā mahana koʻikoʻi.
He haʻahaʻa loa ka coefficient friction o ka mea PTFE, e kōkua ana i ka hōʻemi ʻana i ka torque hana a e maʻalahi a laumania ka hana o nā valves butterfly.
ʻOkoʻa ma waena o ka noho PTFE o ka PTFE Liner:
Ua kāʻei ʻia ka noho valve PTFE ma luna o ke kākoʻo laholio paʻakikī a hoʻokumu pololei ʻia i loko o ke ʻano holoʻokoʻa o ka noho valve.
Hoʻokomo ʻia i loko o ke kino valve e hāʻawi i ka hana sila.
ʻO ka uhi PTFE kahi papa o ka PTFE i hoʻopili ʻia i loko o ke kino valve, me nā ʻaoʻao hopena kahi e pili ai i ka paipu.
Hoʻohana nui ʻia nā kiwikā pepeke PTFE-lined Disc a me nā kiwikā pepeke noho PTFE i nā kemika, nā lāʻau lapaʻau, ka hana mana a me nā ʻoihana ʻē aʻe. Ua hoʻolālā kūikawā ʻia kēia mau kiwikā e kāohi i ke kahe o nā wai ʻino.
Hāʻawi ka uhi PTFE i loko o ka valve i ka pala maikaʻi loa a me ke kūpaʻa wela kiʻekiʻe, e kūpono ana no nā ʻano hana ʻoihana like ʻole. ʻO ka hoʻolālā kaila wafer o kēia mau valves butterfly e māmā ai lākou a maʻalahi hoʻi e hoʻokomo ma waena o nā flanges.
Ua kaulana nā kiwikā pepeke PTFE noho wafer no ko lākou kūpaʻa a me nā koi mālama haʻahaʻa. Hoʻemi ka hoʻolālā disc o ka kiwikā i ka haunaele a hiki ke hoʻonui i nā kahe kahe, e lilo ia i hopena kūpono no nā noi ʻoihana. Hoʻomaʻalahi ka hoʻolālā liʻiliʻi o kēia mau kiwikā i ka hoʻokomo ʻana i nā wahi ʻoihana a mālama i kahi waiwai nui.
