Nūhou - Manual hana a mālama ʻana o nā pahu hōʻoia

1. Ka laulā

Aia nā pae DN i ka DN15mm ~ 600mm (1/2"~ 24") a me nā pae PN mai PN1.6MPa ~ 20MPa (ANSI CLASS150~1500) i hoʻopaʻa ʻia, flanged, BW a me SW swing a hāpai i ka valve check.

2. hoʻohana:

2.1 ʻO kēia valve ka mea e pale ai i ke kahe ʻana o ka waena i hope i ka ʻōnaehana paipu.

2.2 Koho ʻia nā mea valve e like me ka waena.

2.2.1WCB kiwi he kūpono no ka wai, mahu a me ka aila waena etc.

He kūpono ka 2.2.2SS valve no ka corrosion medium.

2.3 Ka wela:

2.3.1 He kūpono ka WCB maʻamau no ka mahana -29 ℃ ~ + 425 ℃

2.3.2Alloy valve kūpono no ka temperature≤550℃

He kūpono ka 2.3.3SS valve no ka mahana-196 ℃ ~ + 200 ℃

3. Hoʻolālā a me nā hiʻohiʻona hana

3.1 ʻO ke ʻano kumu ma lalo nei:

4. Manao hana

Wehe 'akomi 'o Check valve a pani i ka diski no ka pale 'ana i ke kahe 'ana i hope ma o ke kahe waena.

5. Nā kūlana valve kūpono akā ʻaʻole i kaupalena ʻia i:

（1）API 6D-2002 （2）ASME B16.5-2003

（3）ASME B16.10-2000 （4）API 598-2004

6. Ka mālama ʻana a me ka mālama ʻana a me ka hoʻokomo ʻana a me ka hana

6.1 Pono e mālama ʻia ka valve i loko o kahi lumi maloʻo a maikaʻi hoʻi.

6.2 Pono e nānā ʻia a hoʻomaʻemaʻe ʻia nā kiwi ma lalo o ka mālama ʻana i ka manawa lōʻihi, ʻoi aku ka nui o ka noho noho ʻana i mea e pale ai i ka pōʻino o ia mea, a pono e uhi ʻia ka maka noho me ka ʻaila hoʻokaʻawale.

6.3 Pono e nānā ʻia ka mākaʻikaʻi ʻana no ka hoʻohana ʻana.

6.4 Pono e nānā ʻia ka lua valve a me ka ʻili o ka sila ma mua o ke kau ʻana a wehe i ka lepo inā loaʻa.

6.5Pono ke kuhikuhi arrow me ke ala kahe.

6.6 E hoʻokomo pono i ka pahu hoʻopaʻa disiki kū i luna i ka paipu. Pono e hoʻokomo ʻia ka pahu hoʻopaʻapaʻa hoʻopaʻapaʻa hoʻāla i ka paipu.

6.7 Pono e nānā ʻia ka haʻalulu a e ʻike ʻia ka hoʻololi ʻana o ka pipeline medium pressure e pale ai i ka hopena wai.

ʻO nā pilikia, nā kumu a me nā ana hoʻoponopono

Nā Pilikia Hiki	Nā kumu	Ana Hooponopono
ʻAʻole hiki ke wehe a pani paha ka diski	Paʻa loa ka lima pōhaku a me ke kumu pine a paʻa paha kekahi mea Poka lepo i loko o ka valve E nānā i ke kūlana hoʻokūkū Wehe i ka lepo
Leakage	ʻAʻole paʻa ʻo Bolt ʻO ka ʻili o ka ʻili flange sila ʻinoʻino ʻinoʻino Paʻa like Hoʻoponopono E hoʻololi i ka pahu hou
Ka walaʻau a me ka haʻalulu	ʻO ka valve kokoke loa i ka pamu ʻAʻole paʻa ka paʻi haʻahaʻa E hoʻoneʻe i nā kiwikā Wehe i ka loli kaomi

8. Palapala Kauoha

Ma hope o ka hoʻohana ʻia ʻana o ka valve, ʻo 12 mau mahina ka manawa hōʻoia o ka valve, akā ʻaʻole iʻoi aku ma mua o 18 mau mahina ma hope o ka lā hoʻopuka. I loko o ka wā hoʻopaʻa, e hāʻawi ka mea hana i ka lawelawe hoʻoponopono a i ʻole nā ʻāpana ʻokoʻa me ka uku ʻole no ka pōʻino ma muli o ka waiwai, ka hana a i ʻole ka pōʻino inā pololei ka hana.
