Hao kinipopokiwi waihe ʻano valve i hoʻohana ʻia i loko o nā ʻōnaehana pipeline, nona ka hana nui e pale aku i ke kahe mai ke kahe hou ʻana i ka pipeline, ʻoiai e pale ana i ka ʻōnaehana a me ka pipeline mai ka pōʻino i hana ʻia e ka hāmare wai. Hāʻawi ka mea hao ductile i ka ikaika maikaʻi a me ka pale ʻana i ka corrosion, kūpono ia no nā kūlana hana like ʻole.

ʻO ke kumu hana o ka ductile iron non return valve e pili ana i ka ʻokoʻa kaomi i hana ʻia e ke kahe o ka mea waena. Ke holo ka waena i mua, wehe ka valve, e hiki ai i ka wai ke hele i loko. Ke ho'āʻo ka mea waena e kahe i hope, hoʻokuʻu ʻia ka pōleʻa i loko o ka pahu i ka noho kiwi ma lalo o ke kaomi ʻana o ka mea waena, a laila e pani ai i ka valve a pale i ke kahe i hope. Mālama kēia hoʻolālā i ka hana maʻalahi o ka valve me ka ʻole o kahi kumu mana waho.

ʻO nā mea maikaʻi o ka ductile iron non return check valve me:

1. Hoʻolālā paʻa: Ke hoʻohālikelike ʻia me nā kiwi loiloi maʻamau, ʻoi aku ka pōkole o ka lōʻihi o ka lōʻihi o ka lōʻihi, ka liʻiliʻi liʻiliʻi, ke kaumaha māmā, a maʻalahi ke hoʻouka a mālama.

2. Hana maika'i ke sila: me ka ho'ohana 'ana i nā pōpō omaka o ka lā'au e hā'awi i ka hopena sila maika'i a ho'emi i ka leakage.

3. Hoʻopau ʻana: Ke hoʻopau ʻia, hiki iā ia ke hōʻemi i nā nalu hāmare wai, haʻahaʻa haʻahaʻa, a pale i ka ʻōnaehana pipeline.

4. Wear resistance: He maikaʻi ka elasticity a me ke kū'ē kū'ē i ka papa hoʻopili o ka pōʻai, e hoʻonui i ke ola lawelawe o ka valve.

5. Hoʻohana ikaika: Hiki ke hoʻohana ʻia no nā ʻano media like ʻole e like me ka wai anuanu, ka wai wela, ka ʻoihana a me ka hoʻoheheʻe hale, a kūpono no ka hoʻonohonoho ʻana a i ʻole ke kū pono.

6. E ho'ēmi i ka hopena hāmare wai: ʻO ka hoʻolālā ʻana o ka pani wikiwiki e kōkua i ka hōʻemi ʻana i ka hanana hammer wai a pale i ka ʻōnaehana pipeline.

7. Mālama maʻalahi: liʻiliʻi nā ʻāpana, wehe maʻalahi, a hoʻemi i nā kumukūʻai mālama.

No laila, ma muli o ke kiʻekiʻe o ka wela, ke kiʻekiʻe kiʻekiʻe, a me ka corrosive environment, ductile iron check valve 8 inches ua hoʻohana nui ʻia i ka ʻoihana petrochemical e pale i ka backflow medium a hōʻoia i ka palekana a me ka paʻa o ke kaʻina hana. I loko o ka ʻōnaehana inlet a me ka ʻōnaehana wai hānai o ka turbine mahu, hiki i nā ductile iron check valves ke pale i ka hoʻohuli ʻana o ka mahu a me ka wai hānai, e pale ana i ka hana maʻamau o ka ʻāpana. ʻO nā ʻoihana ʻē aʻe e pili ana i ka lako wai kūloko a me nā ʻōnaehana hoʻoheheʻe, nā ʻoihana kemika a me nā lāʻau lapaʻau, ʻoi aku hoʻi i ka ʻoihana mālama wai kaiapuni. I nā ʻōnaehana hoʻomaʻemaʻe wai, hiki i nā kiwi hoʻopaʻa hao ductile ke pale pono i ka hoʻoheheʻe ʻana i hope a hōʻoia i ka palekana o ka wai.

He loea ʻo Jinbin Valve i ka hana ʻana i nā valves no 20 mau makahiki. Ma keʻano he mea hana valve Kina, ke nānā nei mākou i ka noiʻi a me ka hoʻomohalaʻana, e alualu i ka hana hou, a e hana i nā mea a pau e hoʻolako i nā mea kūʻai i nā hopena kūpono. ʻO kā mākou huahana nui e pili ana i ka valve puka maʻamau,kiwi puka puka wai,ʻea damper valve, nā kiwi lele lele nui, nā ʻīpuka puka nui, nā kīwī kīwila kila kila, a me nā mea hou aku. Inā loaʻa iā ʻoe nā pono pili valve, e ʻoluʻolu e kelepona mai iā mākou ma lalo nei. Manaʻo mākou e hana pū me ʻoe!
