I kēia mau lā, he pūʻulu okiwi poepoemai ka hale hana Jinbin e hoʻouna ʻia, me kahi kikoʻī o DN100 a me kahi kaomi hana o PN16. ʻO ke ʻano hana o kēia puʻupuʻu pōleʻa he manual, me ka hoʻohana ʻana i ka ʻaila pāma ma ke ʻano. E hoʻolako ʻia nā kiwi pōpō a pau me nā lima kūpono. Ma muli o ka lōʻihi o nā lima, ʻaʻole lākou e kau ʻia ma ka4 'īniha kinipōpō pōleleno ka lawe ʻana, akā e hoʻopaʻa ʻia ma kahi kaʻawale.

ʻO ka limaʻāhiu pōlele pōleleHe ʻoi aku ka lōʻihi o ke kino valve, a ʻo ka hoʻolālā ʻana o ke kumu valve a me ka paʻa he paʻa nō hoʻi e hoʻokō i nā koi o ka pili flange a me ka torque hana nui. Ua hoʻolālā kūikawā ʻia ke ʻano o ka noho valve e hōʻoia i ka hana sealing ma nā wahi kiʻekiʻe a me nā wela wela.

Ke hoʻohālikelike ʻia i nā ʻano hana ʻē aʻe, ʻo ka pahu flange ball valve ka mea e pono ai: (Flanged Ball Valve Pn16)

1. Hana maikaʻi ke sila

ʻO ke ʻano o ka hoʻopili ʻana o ka flange ball valve e hōʻoia i ka pilina paʻa ma waena o ke kino valve a me ka pipeline, me ka hana hoʻopaʻa sila maikaʻi, hiki ke pale pono i ka leakage waena. Ma lalo o nā kūlana o ke kaomi kiʻekiʻe, ka wela kiʻekiʻe, a i ʻole ka media corrosive, ʻoi aku ka hilinaʻi o kāna hana sila.

2. Li'ili'i hana torque

ʻO ka hoʻolālā maikaʻi ʻia o ka noho valve a me ka hoʻokumu ʻana i ke kumu e hōʻemi ana i ka torque hana o ka lima, e maʻalahi a maʻalahi hoʻi e wehe a pani i ka valve. ʻOiai ma luna o nā kiwi pōpō anawaena nui, ʻoluʻolu hoʻi ka hana lima.

3. Hoʻohana ākea

Ma muli o kāna hana hoʻopaʻa sila maikaʻi a me ke kūpaʻa ikaika o ka puʻuwai, kūpono ka pahu flange ball valve no nā ʻano media like ʻole, me ka wai, ke kinoea, ka aila, ka mahu, a me nā media corrosive. I ka manawa like, hoʻohana nui ʻia ia i nā ʻoihana ʻoihana like ʻole, e like me ka petroleum, kemika, ke kinoea maoli, ka mālama wai, etc.

4. Mālama maʻalahi

Hoʻohālikelike ʻia me ka Ball Valve Industry, ʻo ke ʻano pili pili flange o ka mālama ʻana i nā valve ball flange e ʻoi aku ka maʻalahi o ka mālama ʻana a me ka hoʻololi ʻana. E hoʻoneʻe wale i nā kī no ka wehe ʻana i ka pahu pōpō mai ka pipeline no ka mālama ʻana a i ʻole ke pani ʻana, e mālama nui ana i ka manawa mālama a me nā koina.

5. hilinaʻi kiʻekiʻe

He paʻa ke ʻano o ka valve ball flange, ʻoi aku ka maikaʻi o ka mea, a he hilinaʻi kiʻekiʻe a me ke ola lawelawe. I ka wā lōʻihi o ka hoʻohana ʻana, hiki iā ia ke mālama i ka hana paʻa a hōʻemi i ka hoʻopau ʻana i ka hana a me nā pōʻino palekana i hoʻokumu ʻia e nā hemahema o ka valve.

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