Nā mea e pono ai ʻoe e ʻike e pili ana i nā kiwikā pepeke AWWA

I ka wā e pili ana i nā ʻōnaehana hana wai, ka mālama ʻana i ka wai ʻino, a me nā ʻōnaehana paipu kūlanakauhale, he kakaikahi nā ʻano valve i hilinaʻi ʻia a hoʻohana nui ʻia e like me kakiwikā pulelehua AWWAʻIke ʻia no ko lākou kumukūʻai kūpono, ka maʻalahi o ka hana, a me ke ola lawelawe lōʻihi, he kuleana koʻikoʻi kēia mau kiwikā i ka hoʻoponopono ʻana i ke kahe ʻana i nā ʻōnaehana wai nui. Akā he aha ka mea e hoʻokaʻawale ai iā lākou, a pehea ʻoe e koho ai i ka mea kūpono no kāu noi?

Ma kēia ʻatikala e hāʻawi mākou iā ʻoe i nā mea āpau e pono ai ʻoe e ʻike e pili ana i kaNā kiwikā pulelehua AWWA—mai nā kūlana a me ke kūkulu ʻana a hiki i nā noi a me nā ʻōlelo aʻoaʻo koho koʻikoʻi.

1. He aha ka AWWA Butterfly Valve

An kiwikā pulelehua AWWAhe ʻano kiwikā hapaha-huli i hoʻolālā ʻia e hoʻoponopono a hoʻokaʻawale paha i ke kahe o nā wai, ʻoi aku hoʻi i nā hana wai a me nā ʻōnaehana wai hoʻoneoneo. ʻO ka huaʻōlelo "AWWA" ke kū nei no kaʻAhahui Hana Wai ʻAmelika, ka mea e hoʻonohonoho ai i nā kūlana no ka hoʻolālā, ka hana ʻana, a me ka hana ʻana o nā kiwikā i hoʻohana ʻia i nā ʻōnaehana wai kūlanakauhale a me nā ʻoihana.

ʻO ka kikoʻī maʻamau no kēia mau valvesAWWA C504, e wehewehe ana i nā koi no nā kiwikā pulelehua i noho ʻia me ka laholio mai 3 ʻīniha (75mm) a hiki i 72 ʻīniha (1800mm) ke anawaena.

2. Nā Hiʻohiʻona Koʻikoʻi o nā Kiwikā Pepeiao AWWA

1. Hana Hapahā-Huli
   Hoʻohuli ka diski i 90 degere e wehe piha a pani paha i ke ala kahe, e hiki ai ke hana wikiwiki a me ka pohō iki o ke kaomi.

2. Noho kūpaʻa
   Hoʻohana kēia mau kiwikā i nā noho laholio a elastomeric paha e hōʻoia i kahi sila paʻa a pale i ka liki ʻana, ʻoiai ma hope o ka hoʻohana lōʻihi.

3. Ke kū'ē ʻana i ka palaho
   ʻO nā uhi kūloko a me waho (ʻo ka epoxy maʻamau) e pale i ke kino valve a me ka disc mai ka pala i nā kūlana wai ʻino.

4. Hoʻolālā liʻiliʻi
   Ke hoʻohālikelike ʻia me nā kiwikā puka, ʻoi aku ka māmā o nā kiwikā pepeke AWWA a emi mai ka wahi e lawe ai, he mea kūpono ia no nā hoʻonohonoho paʻa.

5. Ola lawelawe lōʻihi
   Me ka mālama pono ʻana, hiki i kēia mau kiwikā ke mau i nā makahiki he ʻumi i ka lawelawe ʻana, ʻoiai hoʻi i nā noi wai maʻemaʻe.

3.AWWA C504 VS AWWA C516

ʻOiaiAWWA C504uhi i nā kiwikā pulelehua i noho ʻia me ka laholio maʻamau, ʻo ka mea houAWWA C516nā helu wahinā kiwikā pulelehua hana kiʻekiʻe (HPBV), kūpono no ke kaomi kiʻekiʻe a me nā noi koi nui aʻe.

4.Pehea e koho ai i ka AWWA Butterfly Valve kūpono

1. Ka nui o ka paipu a me ka helu kaomi
   E hoʻohālikelike i ka nui a me ka papa o ka valve me nā koi o ka ʻōnaehana. Loaʻa nā valves AWWA i nā papa kaomi he nui (e laʻa, 150A, 150B).

2. Media lawelawe
   E hōʻoia i ka launa pū ʻana me ka wai, ka wai hoʻomaʻemaʻe, a i ʻole nā ​​​​​​wai ʻē aʻe.

3. Nā Kūlana Hana
   E loiloi i nā pae mahana, ke kaomi, a inā pono ka throttling a i ʻole ka hoʻokaʻawale ʻana.

4. Hoʻopau i nā pilina
   Loaʻa nā kiwikā pulelehua AWWA me nā wēlau hui flanged, grooved, a i ʻole mechanical.

5. ʻAno Hana
   E koho ma waena o ka hana kia manual, nā mea hoʻoikaika uila, nā ʻōnaehana pneumatic a hydraulic paha e pili ana i nā pono automation ʻōnaehana.

6. Nā Palapala Hōʻoia
   E hōʻoia i ka kūlike o ka valve me nā kūlana AWWA, a inā hoʻohana ʻia i nā ʻōnaehana wai inu, pono e hōʻoia ʻia e NSF 61.
