Ua komo ʻo Knife gate valve i Kina i ka makahiki 1980.Ma lalo o 20 mau makahiki, ua hoʻonui ʻia kāna noi noi mai nā māla maʻamau a i kahi ākea ākea o nā ʻoihana, mai ka hoʻomākaukau ʻana i ka lanahu, ka hoʻokuʻu ʻana o ka gangue a me ka hoʻokuʻu ʻana o nā mea mana o koʻu mana a hiki i ka hoʻomaʻamaʻa ʻana i ke kūlanakauhale, mai ka ulu ʻana o ka pipeline ʻoihana nui i nā ʻōnaehana pipeline ʻoihana e like me meaʻai, olakino a me ka lāʻau lapaʻau.
ʻO nā ʻano hoʻokele o ka ʻīpuka puka pahi:
Manual, uila, pneumatic, hydraulic, bevel gear, electro-hydraulic a me ka pneumatic a me nā ʻano hoʻokele hydraulic.ʻO ke ʻano o ka ʻīpuka ʻīpuka pahi: ke kumu piʻi a me ke kumu piʻi ʻole.Mea o ka pahi kīpē puka: hao, hoolei kila, kalapona kila, kuhiliʻole kila, fluorine lining, etc. Pahi puka valve seal: paakiki sila, palupalu sila, hookahi-aoao sila, elua-aoao sila a me na mea e ae.
ʻO ke ʻano hoʻonohonoho kūpono ke kumu no ka hana maikaʻi o ka mīkini.Hoʻohana ka ʻīpuka paʻi i ka ʻenehana paʻakikī e like me ka mea nui no ka pani ʻana a me ka anti throttling scouring.I ka manawa like, ua hoʻolālā ʻia me kahi ʻano hana no ka anti throttling scouring.Loaʻa iā ia ka hana ʻelua o ka pani ʻana a i ʻole ka pani ʻana + throttling, a hiki i kona ola lawelawe ke hiki i 10 mau manawa o ka ʻīpuka metala maʻamau.
Me nā mea maikaʻi o ka liʻiliʻi liʻiliʻi, ke kahe liʻiliʻi, ke kaumaha māmā, ka maʻalahi o ka hoʻonohonoho ʻana a me ka wehe ʻana, hoʻoponopono ka ʻīpuka ʻīpuka ʻoi ʻoi i nā pilikia paʻakikī o ke kahe nui ʻana, ke kaumaha kaumaha, ka hoʻokomo paʻakikī a me kahi papahele nui o ka valve puka maʻamau, ka valve puka pā. , kiwi pōʻalo, kiwi hoʻopaʻa, kiwi hoʻoponopono a me kiwi lele.Ma hope o ka ʻike ʻia ʻana o ka ʻīpuka ʻīpuka pahi, ua hoʻololi ʻia kahi helu nui o nā ʻokiʻoki ākea a me nā ʻāpana hoʻoponopono.I kēia mau lā, hoʻohana ʻia ka nui o ka pahu pahu pahi ma ʻAmelika a me Iapana.

ʻO Nortech kekahi o nā mea hana valve ʻoihana nui ma Kina me ka palapala hōʻoia ISO9001.
