I kēia mau lā aku nei, he pūʻulu onā kiwikā poepoemai ka hale hana ʻo Jinbin e hoʻouna ʻia aku, me kahi kikoʻī o DN100 a me kahi kaomi hana o PN16. ʻO ke ʻano hana o kēia pūʻulu o nā kiwikā pōpō he manual, me ka hoʻohana ʻana i ka ʻaila pama ma ke ʻano he medium. E hoʻolako ʻia nā kiwikā pōpō āpau me nā lima e pili ana. Ma muli o ka lōʻihi o nā lima, ʻaʻole lākou e hoʻokomo ʻia ma ka4 ʻīniha poepoe kiwikāno ka lawe ʻana, akā e hoʻopili ʻokoʻa ʻia.

ʻO ka limaʻaoʻao kiwikā pōpōhe ʻano kino valve lōʻihi aʻe, a ʻo ke ʻano o ke kumu valve a me ka lima he paʻa nō hoʻi e hoʻokō i nā koi o ka pilina flange a me ka torque hana nui aʻe. Ua hoʻolālā kūikawā ʻia ke ʻano noho valve e hōʻoia i ka hana sila ʻana i nā wahi kiʻekiʻe a me nā wahi wela kiʻekiʻe.

Ke hoʻohālikelike ʻia me nā ʻano hana ʻē aʻe, ʻo ka valve pōpō flange lima lima nā pono penei: (Flanged Ball Valve Pn16)

1. Hana sila maikaʻi

ʻO ke ʻano hoʻohui flange o ka valve ball flange lima e hōʻoiaʻiʻo i kahi pilina paʻa ma waena o ke kino valve a me ka pipeline, me ka hana sila maikaʻi loa, hiki ke pale pono i ka leakage waena. ʻOi aku ka hilinaʻi o kāna hana sila ma lalo o nā kūlana o ke kaomi kiʻekiʻe, ke mahana kiʻekiʻe, a i ʻole nā ​​​​​​mea corrosive.

2. Ka torque hana liʻiliʻi

ʻO ka hoʻolālā i hoʻonohonoho pono ʻia o ka noho kiwikā a me ke ʻano o ke koʻokoʻo e hōʻemi ana i ka torque hana o ka lima, e maʻalahi ai a maʻalahi hoʻi ke wehe a pani i ka kiwikā. ʻOiai ma nā kiwikā pōpō nui aʻe, he maʻalahi hoʻi ka hana lima.

3. Hoʻohana ākea

Ma muli o kāna hana sila maikaʻi loa a me ke kūpaʻa ikaika i ke kaomi, kūpono ka valve pōpō flange lima no nā ʻano media like ʻole, me ka wai, ke kinoea, ka ʻaila, ka mahu, a me nā media corrosive. I ka manawa like, hoʻohana nui ʻia ia ma nā ʻano ʻoihana like ʻole, e like me ka petroleum, kemika, ke kinoea kūlohelohe, ka mālama wai, a pēlā aku.

4. Mālama maʻalahi

Ke hoʻohālikelike ʻia me ka ʻoihana wiliwili Ball Valve, ʻoi aku ka maʻalahi o ke ʻano hoʻohui flange o nā valves pōpō flange lima e mālama a hoʻololi. E wehe wale i nā bolts e wehe i ka valve pōpō mai ka pipeline no ka mālama ʻana a i ʻole ke hoʻololi ʻana, e mālama nui ana i ka manawa mālama a me nā kumukūʻai.

5. Hilinaʻi kiʻekiʻe

He paʻa ke ʻano o ka valve pōpō flange lima, maikaʻi loa ka mea, a he hilinaʻi kiʻekiʻe a me ke ola lawelawe. I ka wā o ka hoʻohana lōʻihi, hiki iā ia ke mālama i ka hana paʻa a hōʻemi i nā hōʻemi hana a me nā ulia palekana i hoʻokumu ʻia e ka hemahema o ka valve.

→Inā he mau pono kūpono kāu, hiki iā ʻoe ke waiho i kahi leka ma lalo nei e hoʻokaʻaʻike mai iā mākou, a e loaʻa iā ʻoe kahi pane i loko o 24 mau hola!
