Pono ʻoe e kūʻai i nā kiwikā PVC no kahi papahana, akā nui loa ka papa inoa. Pōpō, nānā, pulelehua, diaphragm—ʻo ke koho ʻana i ka mea hewa ʻo ia hoʻi kahi ʻōnaehana e liki ana, hāʻule, a hana pono ʻole paha.

Ua hoʻokaʻawale ʻia nā ʻano nui o nā kiwikā PVC e kā lākou hana: nā kiwikā pōpō no ka hoʻomalu ʻana/hoʻopau ʻana, nā kiwikā nānā e pale i ke kahe hou ʻana, nā kiwikā pepeke no ka hoʻoluhi ʻana i nā paipu nui, a me nā kiwikā diaphragm no ka lawelawe ʻana i nā wai ʻino a i ʻole nā ​​​​wai hoʻomaʻemaʻe.

He nīnau kēia aʻu e kūkākūkā pinepine ai me kaʻu mau hoa hana, me Budi, he luna kūʻai kiʻekiʻe ma Indonesia. Pono kāna mau mea kūʻai aku, mai nā mea hana a hiki i nā mea kūʻai aku, e ʻike e loaʻa ana iā lākou ka mea hana kūpono no ka hana.ʻōnaehana paipuʻo ia wale nō ka ikaika e like me kona ʻāpana nāwaliwali loa, a ke koho ʻana i ka mea kūponoʻano kiwikāʻo ia ke kaʻina 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 kekahi mau ʻano like ʻole o nā kiwikā PCV?

Lohe ʻoe i ka huaʻōlelo "PVC valve" a manaʻo paha he huahana maʻamau hoʻokahi ia. Hiki i kēia kuhi ke alakaʻi iā ʻoe e hoʻokomo i kahi valve i hiki ʻole ke lawelawe i ke kaomi a i ʻole e hana i ka hana āu e pono ai.

ʻAe, he nui nā ʻano kiwikā PVC, kēlā me kēia me kahi ʻano hana kūloko kū hoʻokahi i hoʻolālā ʻia no kahi hana kikoʻī. ʻO ka mea maʻamau no ka hoʻomaka/hoʻōki ʻana i ke kahe (nā kiwikā pōpō) a me ka pale ʻakomi ʻana i ke kahe hoʻi (nā kiwikā nānā).

ʻO ka manaʻo ʻana he like nā kiwikā PVC a pau he kuhihewa maʻamau ia. ʻO ka ʻoiaʻiʻo, ʻo ka ʻāpana "PVC" e wehewehe wale ana i ka mea i hana ʻia ai ka kiwikā—he palaki paʻa, pale i ka pala. ʻO ka ʻāpana "kiwikā" e wehewehe ana i kāna hana. No ke kōkua ʻana iā Budi a me kāna hui e alakaʻi i kā lākou mea kūʻai aku, ua hoʻokaʻawale mākou iā lākou e kā lākou hana nui. Kōkua kēia hoʻokaʻawale maʻalahi i nā mea a pau e koho i ka huahana kūpono me ka hilinaʻi.

Eia kahi wehewehe maʻalahi o nā ʻano maʻamau āu e hālāwai ai i ka hoʻokele wai:

He aha nā ʻano PVC ʻehā?

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

ʻO kēia nīnau e pili ana i ka mea palakiko, ʻaʻole ke ʻano o ka valve. ʻO nā mea ʻehā maʻamau o ka ʻohana PVC ʻo ia ka PVC-U (maʻamau, no ka wai anuanu), C-PVC (no ka wai wela), PVC-O (ikaika kiʻekiʻe), a me M-PVC (i hoʻololi ʻia e ka hopena).

He nīnau kupaianaha kēia no ka mea e pili ana i ka puʻuwai o ka maikaʻi o ka huahana a me ka palekana o ka noi. he mea maʻalahi ke huikau i nā ʻano valve me nā ʻano mea. Ma Pntek, ke manaʻoʻiʻo nei mākou he hoa kūleʻa kahi hoa i aʻo ʻia, no laila he mea nui ka wehewehe ʻana i kēia. ʻO ka mea i hana ʻia ai kāu valve e kuhikuhi i kona mau palena mahana, ka helu kaomi, a me ke kū'ē ʻana i nā kemika.

PVC-U (Polyvinyl Chloride i hoʻopili ʻole ʻia)

ʻO kēia ke ʻano PVC maʻamau i hoʻohana ʻia no nā paipu, nā mea hoʻopili, a me nā kiwikā ma ʻAmelika ʻĀkau, ʻEulopa, a me ʻAsia. He paʻa, kūpono ke kumukūʻai, a kūpaʻa loa i nā ʻano kemika like ʻole. ʻO ia ke kūlana maʻamau no nā noi wai anuanu. ʻO ka hapa nui o kā mākou mau kiwikā pōpō Pntek a me nā kiwikā nānā i kauoha ʻia e Budi ua hana ʻia mai ka PVC-U kiʻekiʻe.

C-PVC (Polyvinyl Chloride i hoʻohui ʻia me ka chlorine)

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

Nā ʻAno ʻē aʻe

ʻAʻole maʻamau ka PVC-O (Oriented) a me M-PVC (Modified) no nā valves a ʻoi aku ka nui no nā paipu kaomi kūikawā, akā he mea maikaʻi ke ʻike aia lākou. Ua hana ʻia lākou no nā helu kaomi kiʻekiʻe a me ka ikaika hopena maikaʻi aʻe.

He aha nā ʻano nui ʻeono o nā kiwikā?

Ke kūkulu nei ʻoe i kahi ʻōnaehana paʻakikī a pono ʻoe i nā mea ʻoi aku ma mua o kahi kiwikā 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 kiwikā pōpō PVC.

ʻO nā ʻohana hana nui ʻeono o nā kiwikā ʻo Ball, Gate, Globe, Check, Butterfly, a me Diaphragm. Loaʻa ka hapa nui ma PVC e lawelawe i nā noi kahi e popopo ai nā kiwikā metala a pipiʻi paha.

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 mua o nā mea ʻē aʻe. ʻO kekahi he mau kūlana ʻoihana, aʻo kekahi no nā hana kikoʻī loa. Kōkua kēia ʻike ākea i ka hui a Budi e pane i nā nīnau kikoʻī loa o ka mea kūʻai aku.

No ka mālama wai maʻamau,nā kiwikā poepoe, nā kiwikā nānā, a menā kiwikā pepekeʻo ia nā ʻano PVC nui loa e pono e ʻike.

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

Pono ʻoe i kahi valve nānā e pale aku ai i ke kahe hou ʻana, akā ʻike ʻoe i nā koho e like me "swing," "ball," a me "spring." ʻO ke kau ʻana i ka mea hewa hiki ke alakaʻi i ka hemahema, ka hāmare wai, a i ʻole ka valve ʻaʻole hana iki.

ʻO nā ʻano nui o nā kiwikā nānā PVC he nānā wili, nānā pōpō, a me ka nānā puna. Hoʻohana kēlā me kēia i kahi ʻano hana passive ʻokoʻa e hoʻōki i ke kahe hoʻihoʻi a kūpono no nā ʻano paipu like ʻole a me nā kūlana kahe.

ʻO ka valve nānā ke kiaʻi mālie o kāu ʻōnaehana, e hana aunoa ana me ka ʻole o nā lima a i ʻole ka mana o waho. Akā, ʻaʻole hana like nā kiaʻi āpau. He mea koʻikoʻi ke koho ʻana i ka mea kūpono no ka pale ʻana o ka pamu a me ka pono o ka ʻōnaehana. He kikoʻī kēia aʻu e hoʻokūpaʻa mau nei me Budi, no ka mea, pili pololei ia i ka hilinaʻi lōʻihi o nā hoʻonohonoho ʻana o kāna mea kūʻai aku.

Kiwikā Hōʻoia Swing PVC

ʻO kēia ke ʻano maʻalahi loa. Loaʻa iā ia kahi ʻaoʻao hinged (a i ʻole disc) e wehe ana me ke kahe ʻana o ka wai. Ke pau ke kahe ʻana a i ʻole e hoʻihoʻi ʻia, hoʻohuli ke koʻikoʻi a me ke kaomi hope i ka ʻaoʻao pani i kona noho. Hana maikaʻi lākou i nā paipu ākea a i ʻole nā ​​​​paipu kū pololei me ke kahe i luna.

Kiwikā Hōʻoia Pōpō PVC

ʻO kēia kā mākou hana kūikawā ma Pntek. Aia kahi pōpō poepoe i loko o kahi keʻena. Hoʻokuke ke kahe i mua i ka pōpō i waho o ke ala kahe. Ke hoʻohuli ke kahe, hoʻokuke ia i ka pōpō i loko o ka noho, e hana ana i kahi sila paʻa. He hilinaʻi loa lākou, hiki ke hoʻokomo ʻia i luna a i ʻole ka pae, a ʻaʻohe hinges a i ʻole nā ​​​​puna e pau ai.

Kiwikā Hōʻoia Puna PVC

Hoʻohana kēia ʻano i kahi 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 haʻalulu hōʻino i hana ʻia e ka hoʻōki koke ʻana o ke kahe. Hiki ke hoʻokomo ʻia i kēlā me kēia ʻano.

Hopena

ʻO ke koho ʻana i ka valve PVC kūpono, ʻo ia hoʻi ka hoʻomaopopo ʻana i kona ʻano—pōpō no ka hoʻomalu ʻana, ka nānā ʻana i ke kahe hope—a me ka mea plastik ponoʻī. Hōʻoia kēia ʻike i ka hilinaʻi o ka ʻōnaehana, pale i nā hemahema, a kūkulu i ka hilinaʻi o ka mea kūʻai aku.
