Pono ʻoe e kūʻai i nā valve PVC no kahi papahana, akā ʻoi aku ka nui o ka waihona. Poepoe, nānā, pepeke, diaphragm—ke koho ʻana i ka mea hewa, ʻo ia hoʻi, he ʻōnaehana lele, hāʻule, a ʻaʻole holo pololei.

Hoʻokaʻawale ʻia nā ʻano nui o nā valve PVC e kā lākou hana: nā pahu pōlele no ka mana on / off, nānā i nā valve e pale i ka hoʻihoʻi ʻana, nā valve butterfly no ka throttling pipes nui, a me nā valve diaphragm no ka mālama ʻana i nā wai corrosive a maʻemaʻe paha.

He nīnau kēia aʻu e kamaʻilio pinepine ai me kaʻu mau hoa, me Budi, he luna kūʻai kiʻekiʻe ma Indonesia. ʻO kāna mau mea kūʻai mai, mai nā ʻaelike a hiki i nā mea kūʻai aku, pono lākou e ʻike i ka loaʻa ʻana o ka mea hana kūpono no ka hana. Aʻōnaehana paipuʻO ka ikaika wale nō e like me kona mea nāwaliwali loa, a koho i ka pololeiʻano valveʻo ia ka hana mua i ke kūkulu ʻana i kahi ʻōnaehana hilinaʻi a lōʻihi. ʻO ka hoʻomaopopo ʻana i kēia mau ʻokoʻa ʻaʻole ia he ʻike loea wale nō; ʻo ia ke kumu o kahi papahana holomua.

Aia nā ʻano ʻokoʻa o nā pahu PCV?

Lohe ʻoe i ka huaʻōlelo “PVC valve” a manaʻo paha ʻoe he huahana maʻamau. Hiki i kēia manaʻo ke alakaʻi iā ʻoe e hoʻokomo i kahi valve hiki ʻole ke mālama i ke kaomi a hana paha i ka hana āu e pono ai.

ʻAe, he nui nā ʻano o nā valve PVC, kēlā me kēia me kahi mīkini kūloko kū hoʻokahi i hoʻolālā ʻia no kahi hana kikoʻī. ʻO ka mea maʻamau no ka hoʻomaka ʻana/ka hoʻokuʻu ʻana i ke kahe (nā pahu pōlele) a me ka pale ʻana i ka hoʻihoʻi ʻana (nā pahu pahu).

ʻO ka noʻonoʻo ʻana he like nā valve PVC a pau he hewa maʻamau. ʻO ka ʻoiaʻiʻo, ʻo ka ʻāpana "PVC" e wehewehe wale i ka mea i hana ʻia ai ka pahu mai loko mai o ka paʻa paʻa a paʻa i ka corrosion. ʻO ka māhele "valve" e wehewehe i kāna hana. No ke kōkua ʻana iā Budi a me kāna hui e alakaʻi i kā lākou mea kūʻai, hoʻokaʻawale mākou iā lākou e kā lākou hana mua. ʻO kēia hoʻonohonoho maʻalahi e kōkua i nā mea a pau e koho i ka huahana kūpono me ka hilinaʻi.

Eia kahi wehewehe kumu o nā ʻano maʻamau āu e ʻike ai i ka hoʻokele wai:

He aha nā ʻano ʻehā o PVC?

ʻIke ʻoe i nā lepili like ʻole e like me PVC-U a me C-PVC a noʻonoʻo inā pili lākou. ʻO ka hoʻohana ʻana i ka valve maʻamau i loko o kahi laina wai wela no ka mea ʻaʻole ʻoe i ʻike i ka ʻokoʻa hiki ke kumu i ka pōʻino.

ʻO kēia nīnau e pili ana i ka mea plastik, ʻaʻole ke ʻano valve. ʻO nā mea PVC-ʻohana maʻamau ʻehā he PVC-U (maʻamau, no ka wai anuanu), C-PVC (no ka wai wela), PVC-O (ikaika kiʻekiʻe), a me M-PVC (impact-modified).

He nīnau maikaʻi kēia no ka mea hiki i ka puʻuwai o ka maikaʻi o ka huahana a me ka palekana noi. maʻalahi nā ʻano valve me nā ʻano mea. Ma Pntek, ke manaʻoʻiʻo nei mākou he hoa kūleʻa ka hoa hoʻonaʻauao, no laila he mea koʻikoʻi ka wehewehe ʻana i kēia. ʻO ka mea i hana ʻia i kāu valve e kuhikuhi i kona mau palena wela, ka helu kaomi, a me ke kūpaʻa kemika.

PVC-U (Polyvinyl Chloride ʻAʻole i hoʻopili ʻia)

ʻO kēia ke ʻano maʻamau o PVC i hoʻohana ʻia no nā paipu, nā mea pono, a me nā kiwi ma ʻAmelika ʻĀkau, ʻEulopa, a me Asia. He ʻoʻoleʻa, ʻoi aku ka maikaʻi o ke kumu kūʻai, a kūpaʻa loa i nā ʻano kemika. ʻO ia ka maʻamau no nā noi wai anuanu. ʻO ka hapa nui o kā mākou Pntek ball valve a nānā i nā kiwi a Budi i hana ʻia mai ka PVC-U kiʻekiʻe.

C-PVC (Chlorinated Polyvinyl Chloride)

Hele ʻo C-PVC i kahi kaʻina hana chlorination. Hoʻonui nui kēia hoʻololi maʻalahi i kona pale wela. ʻOiai e hoʻohana wale ʻia ka PVC-U a hiki i 60°C (140°F), hiki iā C-PVC ke mālama i nā mahana a hiki i 93°C (200°F). Pono ʻoe e hoʻohana i nā kiwi C-PVC no nā laina wai wela.

Nā ʻano ʻē aʻe

ʻAʻole maʻamau ka PVC-O (Oriented) a me M-PVC (Modified) no nā kiwikā a ʻoi aku ka nui no nā paipu kaomi kūikawā, akā maikaʻi ke ʻike aia lākou. Hoʻolālā ʻia lākou no nā pae kiʻekiʻe o ke kaomi a me ka ikaika hopena maikaʻi.

He aha nā ʻano kiwi nui ʻeono?

Ke kūkulu nei ʻoe i kahi ʻōnaehana paʻakikī a pono ʻoe ma mua o kahi valve on/off maʻalahi. ʻO ka ʻike ʻana i nā inoa e like me "Globe" a i ʻole "Gate" hiki ke huikau inā ʻoe e hana nui me nā pahu pōpō PVC.

ʻO nā ʻohana hana nui ʻeono o nā kiwi, ʻo ia ka Ball, Gate, Globe, Check, Butterfly, a me Diaphragm valves. Loaʻa ka hapa nui i ka PVC no ka lawelawe ʻana i nā noi kahi e ʻino ai nā pahu metala a ʻoi aku ka pipiʻi.

ʻOiai mākou e kālele ana i nā ʻano PVC maʻamau, ʻo ka hoʻomaopopo ʻana i ka ʻohana valve holoʻokoʻa e kōkua iā ʻoe e ʻike i ke kumu i koho ʻia ai kekahi mau valve ma luna o nā mea ʻē aʻe. ʻO kekahi nā kūlana ʻoihana, aʻo nā mea ʻē aʻe no nā hana kikoʻī loa. Kōkua kēia ʻike ākea i ka hui o Budi e pane i nā nīnau kikoʻī loa o nā mea kūʻai aku.

No ka hooponopono wai nui,kiwi poepoe, nā pahu hopu, akiwi leleʻo ia nā ʻano PVC koʻikoʻi e ʻike.

He aha nā ʻano ʻano like ʻole o nā kiwi nānā PVC?

Pono ʻoe i ka valve check no ka pale ʻana i ka hoʻi hope, akā ʻike ʻoe i nā koho e like me "swing," "ball," a me "spring." ʻO ka hoʻokomo ʻana i ka mea hewa hiki ke alakaʻi i nā hemahema, ka hāmare wai, a i ʻole ka hana ʻole o ka valve.

ʻO nā ʻano nui o nā ʻāpana nānā PVC ʻo ka nānā ʻana i ka swing check, ball check, and spring check. Hoʻohana kēlā me kēia i kahi mīkini passive ʻē aʻe e hoʻōki i ke kahe ʻana a kūpono i nā ʻano paipu like ʻole a me nā kūlana kahe.

ʻO ka valve check ka mea mālama leo o kāu ʻōnaehana, e hana maʻalahi me ka ʻole o nā lima a i ʻole ka mana o waho. Akā ʻaʻole hana like nā kahu a pau. He mea koʻikoʻi ke koho ʻana i ka mea kūpono no ka pale ʻana i ka paila a me ka pono o ka ʻōnaehana. He kikoʻī kēia aʻu e hoʻoikaika mau nei me Budi, no ka mea, pili pololei ia i ka hilinaʻi lōʻihi o kāna mau mea kūʻai aku.

PVC Swing Check Valve

ʻO kēia ke ʻano maʻalahi. Hōʻike ʻia ia i kahi flap hinged (a i ʻole disc) e hāmama me ke kahe o ka wai. Ke kū a hoʻohuli paha ke kahe, ʻo ka ʻumekaumaha a me ke kaomi hope e koli i ka pā e pani i kona noho. Hana maikaʻi lākou i nā paipu ākea a i ʻole nā ​​paipu kūpaʻa me ke kahe i luna.

ʻO ka pahu hoʻopaʻa pōpō PVC

ʻO kēia kā mākou mea kūikawā ma Pntek. Noho ka poepoe poepoe ma ke keena. Hoʻokuʻu ke kahe i mua i ka pōleʻa mai ke ala kahe. Ke hoʻohuli ke kahe, hoʻihoʻi ʻo ia i ka pōleʻa i loko o ka noho, hana i kahi sila paʻa. Hiki iā lākou ke hilinaʻi nui, hiki ke hoʻokomo ʻia ma ka ʻaoʻao a i ʻole ma ka ʻaoʻao, ʻaʻohe hinges a i ʻole nā ​​​​punawai e pau ai.

ʻO ka pahu hōʻoia punawai PVC

Hoʻohana kēia ʻano i ka pūnāwai e kōkua i ka pani wikiwiki ʻana i ka valve ke pau ke kahe. He mea maikaʻi loa kēia hana pani wikiwiki no ka pale ʻana i ka hāmare wai—ka hawewe pōʻino i hana ʻia e ka hoʻōki koke ʻana i ke kahe. Hiki iā lākou ke hoʻokomo i kēlā me kēia orientation.

Ka hopena

ʻO ke koho ʻana i ka valve PVC kūpono, ʻo ia ka hoʻomaopopo ʻana i kona ʻano - pōpō no ka mālama ʻana, e nānā no ka hoʻihoʻi ʻana - a me ka mea plastik ponoʻī. Mālama kēia ʻike i ka hilinaʻi o ka ʻōnaehana, pale i nā hemahema, a kūkulu i ka hilinaʻi o ka mea kūʻai aku.
