ʻO kēlā me kēia hulina pūnaewele wikiwiki no ka valve e hōʻike i nā hopena like ʻole: manual a ʻakomi paha, keleawe a i ʻole ke kila kila, flanged a i ʻole NPT, hoʻokahi ʻāpana, ʻelua a ʻekolu ʻāpana, a pēlā aku. Me ka nui o nā ʻano valve e koho ai, pehea ʻoe e maopopo ai ke kūʻai nei ʻoe i ke ʻano kūpono? ʻOiai e kōkua kāu noi i ke alakaʻi ʻana iā ʻoe i ke koho ʻana i ka valve kūpono, he mea nui e loaʻa i kahi ʻike kumu o nā ʻano ʻano valve i hāʻawi ʻia.

He kino hoʻoheheʻe paʻa ko ka ʻāpana pōpō pōleʻa hoʻokahi e hōʻemi i ka pilikia o ka leakage. He maʻalahi lākou a ʻaʻole hoʻoponopono ʻia.

ʻO nā ʻāpana kinipōpō ʻelua kekahi o nā mea maʻamau i hoʻohana ʻiakiwi poepoe. E like me ka inoa i hōʻike ʻia, ʻelua ʻāpana pōpō pōleʻa ʻelua ʻāpana, kahi ʻāpana me kahi ʻāpana i hoʻopili ʻia ma kekahi ʻaoʻao a me ke kino valve. Hoʻopili ka ʻāpana ʻelua ma luna o ka ʻāpana mua, paʻa i ka ʻoki ma kahi a me ka pili hope ʻelua. Ke kau ʻia, ʻaʻole hiki ke hoʻoponopono ʻia kēia mau valve ke ʻole lākou e lawe ʻia mai ka lawelawe.

Eia hou, e like me ka inoa i hōʻike ʻia, ʻekolu ʻāpana ʻāpana pōleʻa ʻekolu ʻāpana: ʻelua mau pāpale a me kahi kino. Hoʻopili maʻamau a hoʻopaʻa ʻia nā pāpale hope i ka paipu, a hiki ke wehe maʻalahi ke kino no ka hoʻomaʻemaʻe a hoʻoponopono ʻole me ka wehe ʻole ʻana i ka pāpale hope. Hiki i kēia ke koho nui loa no ka mea e pale ana i ka laina hana mai ka pani ʻana i ka wā e pono ai ka mālama.

Ma ka hoʻohālikelike ʻana i nā hiʻohiʻona o kēlā me kēia valve me kāu koi noi, hiki iā ʻoe ke hana i kahi hoʻoholo hoʻoholo i kūpono i kāu mau pono. E kipa i kā mākou pūnaewele valve e aʻo e pili ana i kā mākou laina huahana valve a i ʻole e hoʻomaka e hoʻonohonoho i kēia lā.

Hōʻike UV
Keʻokeʻopaipu PVC,ʻO ke ʻano i hoʻohana ʻia no ka paipu, wāwahi i ka wā e ʻike ʻia ai i ke kukui UV, e like me ka lā. ʻAʻole kūpono kēia mea no nā noi waho kahi e uhi ʻole ʻia ai, e like me nā pou hae a me nā noi hale. I ka wā lōʻihi, hoʻemi ka hoʻolaha ʻana o UV i ka maʻalahi o ka mea ma o ka polymer degradation, hiki ke alakaʻi i ka hoʻokaʻawale ʻana, ka haki ʻana, a me ka ʻokiʻoki.

haʻahaʻa wela
Ke hāʻule ka mahana, lilo ka PVC i mea palupalu. Ke hōʻike ʻia i nā mahana maloʻo no nā manawa lōʻihi, e lilo ia i mea palupalu a maʻalahi. ʻAʻole kūpono ʻo PVC no nā noi e pili ana i nā mahana maloʻo like ʻole, ʻaʻole pono e maloʻo ka wai i lokoNā paipu PVCno ka mea, hiki ke hana i ka pohā a me ka pohā.

makahiki
ʻO nā polymers a me nā plastics a pau e hoʻohaʻahaʻa i kekahi degere i ka manawa. He huahana ia o kā lākou hui ʻana. I ka wā lōʻihi, hoʻopili ʻo PVC i nā mea i kapa ʻia he plasticizers. Hoʻohui ʻia nā plasticizers i ka PVC i ka wā o ka hana ʻana e hoʻonui i kona maʻalahi. Ke neʻe lākou i waho o nā paipu PVC, ʻaʻole i liʻiliʻi wale nā ​​paipu ma muli o ka nele o lākou, akā waiho pū ʻia me nā hemahema ma muli o ka nele o nā molekala plasticizer, hiki ke hana i nā māwae a i ʻole nā ​​​​fissures i nā paipu.

hōʻike kemika
Hiki i nā paipu PVC ke lilo i palupalu mai ka ʻike kemika. Ma ke ʻano he polymer, hiki i nā kemika ke loaʻa kahi hopena maikaʻi ʻole i ka hana ʻana o PVC, wehe i nā mea paʻa ma waena o nā molekala i loko o ka plastic a me ka wikiwiki i ka neʻe ʻana o nā plasticizers mai nā paipu. Hiki i nā paipu ho'okahe PVC ke lilo i mea ma'alahi ke 'ike 'ia i nā kinikini he nui, e like me nā mea i loa'a i loko o nā mea ho'okahe wai.
