5. Disc: ka disc o nā ʻāpana i pani ʻia a puni ke axis o ka noho;
6. Paheʻe kiwi: paheʻe ka ʻāpana pani ma ke ala pololei i ke kahawai.
ʻEkolu, e like me ka hoʻohana ʻana, e like me ka hoʻohana ʻana o ka valve hiki ke hoʻokaʻawale ʻia:
1. Hoʻohana hoʻohana ʻia: hoʻohana ʻia e hoʻokomo a ʻoki ʻia paha i ke ʻano o ka pipeline, e like me ka valve globe, valve gate, ball valve, butterfly valve, etc.
2. Nānā: hoʻohana ʻia e pale i ka hoʻihoʻi ʻana o ka media, e like me nā kiwi loiloi.
3 hoʻoponopono: hoʻohana ʻia e hoʻoponopono i ke kaomi a me ke kahe o ka waena, e like me ka hoʻoponopono ʻana i ka valve, ka hoʻohaʻahaʻa ʻana i ke kaomi.
4. Hoʻolaha: hoʻohana ʻia e hoʻololi i ke kahe o ka medium, medium distribution, e like me ka moa ala ʻekolu, ka valve distribution, slide valve, etc.
5 palekana palekana: i ka wā i ʻoi aku ka nui o ke kaomi waena ma mua o ka waiwai i ʻōlelo ʻia, hoʻohana ʻia ia e hoʻokuʻu i ke kikowaena nui e hōʻoia i ka palekana o ka ʻōnaehana pipeline a me nā lako, e like me ka valve palekana a me ka valve ulia pōpilikia.
6. ʻO nā hoʻohana kūikawā ʻē aʻe: e like me ka pahele pahele, ka puka makani, ka pahu wai, etc.
7.Four, e like me ke kaʻa kaʻa, e like me ka okoa kaʻa kaʻa hiki ke maheleia:
1. Manual: me ke kōkua o ka huila lima, ka lima, ka lever a i ʻole ka sprocket, a me nā mea ʻē aʻe, me ka hoʻokele kanaka, e hoʻokele i ka nui torque fashion worm gear, gear a me nā mea deceleration ʻē aʻe.
2. Uila: hoʻokele ʻia e kekahi kaʻa a mea uila ʻē aʻe.
3. Hydraulic: E hoʻokele me ke kōkua o (wai, aila).
4. Pneumatic: alakaʻi ʻia e ka ea paʻa.
ʻElima, e like me ke kaomi, e like me ke kaomi nominal o ka valve hiki ke hoʻokaʻawale ʻia:
1. Vacuum valve: ke kaomi piha < ʻO nā valve me ke kiʻekiʻe o 0.1mpa, a i ʻole 760mm hg, e hōʻike pinepine ʻia e ka mm hg a i ʻole mm kolamu wai.
2. ʻO ke kaomi haʻahaʻa haʻahaʻa: kaomi nominal PN≤ 1.6mpa valve (me ka PN≤ 1.6mpa steel valve)
3. Medium pressure valve: nominal pressure PN2.5-6.4mpa valve.
4. Kiʻekiʻe kiʻekiʻe kaomi valve: nominal kaomi PN10.0-80.0mpa valve.
5. Super kiʻekiʻe kiʻekiʻe puʻe kiwi: nominal kaomi PN≥ 100.0mpa valve.
ʻEono, e like me ka mahana o ka waena, e like me ka valve e hana ana i ka mahana wela hiki ke hoʻokaʻawale ʻia:
1. ʻO ka pahu maʻamau: kūpono no ka mahana wela -40 ℃ ~ 425 ℃ valve.
2. Kiʻekiʻe wela wela: kūpono no ka wela wela 425 ℃ ~ 600 ℃ valve.
3. Heat resistant valve: kūpono no ke ana wela ma luna o 600 ℃ valve.
4. Haʻahaʻa wela wela: kūpono no ka mahana wela -150 ℃ ~ -40 ℃ valve.
5. Ultra-haʻahaʻa wela wela: kūpono no ka mahana wela ma lalo -150 ℃ valve.
ʻEhiku, e like me ke anawaena nominal, e like me ke anawaena nominal o ka valve hiki ke hoʻokaʻawale ʻia:
1. Li'ili'i anawaena valve: nominal anawaena DN<40mm valve.
2. Medium diameter valve: nominal diameter DN50 ~ 300mm valve.
3. Nui anawaena valve: nominal anawaena DN350 ~ 1200mm valve.
4. Oversized anawaena valve: nominal anawaena DN≥1400mm valve.
Viii.Hiki ke hoʻokaʻawale ʻia e like me ke ʻano pili o ka valve a me ka pipeline:
1. Flanged kiwikā: kiwikā kino me flanged, a me ka paipu me flanged kiwikā.
2. Uila pilina pili: kino kiwi me ka lola loko a i ʻole ke kaula waho, ka valve pili pili me ka pipeline.
3. Welded pilina kiwikā: kiwikā kino me welds, a me na paipu me welded kiwikā.
4. Kiwikā pili pili: kino kiwikā me ka paʻa, a me ka paipu paʻa pili puwikā.
5. ʻO ka valve pili lima: pili ka valve me ka lima a me ka pipeline.
