ʻIke Hoʻokomo Valve Maʻamau #1

Nānā ma mua o ka hoʻokomo ʻana i ka valve

① E nānā pono i kakiwikāʻO ke kumu hoʻohālike a me nā kikoʻī e kūpono i nā koi o ke kaha kiʻi.
② E nānā inā hiki ke wehe ʻia ke kumu valve a me ka disc valve me ka maʻalahi, a inā paʻa a wili paha.
③ E nānā inā ua pōʻino ka valve a inā pololei a paʻa ke kaula o ka valve threaded.
④ E nānā inā paʻa ka hui ʻana o ka noho valve a me ke kino valve, ka pilina ma waena o ka disc valve a me ka noho valve, ka uhi valve a me ke kino valve, a me ke kumu valve a me ka disc valve.
⑤ E nānā inā kūpono ka pahu valve, ka hoʻopili a me nā mea hoʻopaʻa (bolts) i nā koi o ka mea hana.
⑥ Pono e wehe ʻia ka pahu hoʻoluhi kaomi kahiko a lōʻihi paha, a hoʻomaʻemaʻe ʻia ka lepo, ke one a me nā ʻōpala ʻē aʻe me ka wai.
⑦ Wehe i ka uhi awa, e nānā i ke kēkelē hoʻopaʻa, a pono e pani paʻa i ka disc valve.

Ka ho'āʻo paʻi o ka valve

Pono e ho'āʻo i ka ikaika a me ka ho'āʻo paʻa, a me nā puʻupuʻu kila kila i ka nānāʻana o ka pūpū i kēlā me kēia, a pono e nānāʻia nā mea.

1. Ka ho'āʻo ikaika o ka valve
ʻO ka ho'āʻo ikaika o ka valve e ho'āʻo i ka valve ma ka moku'āina ākea e nānā i ka leakage ma kaʻili o waho o ka valve.No nā valve me PN≤32MPa, ʻo ka hoʻāʻo ʻana he 1.5 mau manawa o ke kaomi nominal, ʻaʻole emi ka manawa hoʻāʻo ma mua o 5min, a ʻaʻohe leakage ma ka pūpū a me ka ʻōpala paʻa e pono ai.

2. Ho'āʻo paʻa o ka valve
Hoʻokō ʻia ka hoʻāʻo me ka paʻa paʻa ʻana o ka valve e nānā inā he leakage ma ka ʻili hoʻopaʻa o ka valve.ʻO ke kaomi hoʻāʻo, koe naʻe no nā ʻūhā butterfly, nā kiwi nānā, nā kiwi lalo, a me nā kīwaha throttle, pono e hoʻokō maʻamau i ke kaomi nominal.Ke hoʻohana ʻia ke kaomi hana, hiki ke hoʻāʻo ʻia me 1.25 mau manawa o ke kaomi hana, a kūpono ia inā ʻaʻole leak ka ʻili o ka ʻili o ka valve.

E pili ana iā CVG Valve

CVG ValveHe mea kūikawā i ka hoʻomohala ʻana a me ka hana ʻana i nā kiwi lele lele haʻahaʻa a me waena, nā ʻīpuka puka, nā kiwi pōpō, nā kiwi nānā, nā ʻano o nā kiwi hana, nā kiwi hoʻolālā kūikawā, nā kiwi hoʻopilikino a me nā hui hoʻokaʻawale pipeline.ʻO ia hoʻi ke kumu hana nui o nā kīwaha butterfly nui mai DN 50 a 4500 mm.
