He mea hana ʻoihana ʻo Zhongfa Valve i nā ʻāpana valve butterfly a me nā valve butterfly, i hoʻokumu ʻia i ka makahiki 2006, e hāʻawi ana i nā ʻāpana valve a me nā ʻāpana butterfly valve i nā ʻāina ʻoi aku ma mua o 20 o ka honua, aʻe, e hoʻomaka ʻo Zhongfa Valve i kahi kikoʻī kikoʻī o nā ʻāpana valve butterfly.
ʻO ka valve butterfly nā ʻāpana aʻe, ʻo ka inoa o nā ʻāpana butterfly he kino valve, valve Disc, valve shaft, valve seat, sealing surface, and operation actuator, i kēia manawa, e hoʻolauna mākou i kēia mau ʻāpana valve butterfly.
# 1 Nā ʻāpana kiwi kīpē--Kino kiwi
Kūkākūkā mākou i ke kino valve e pili ana i ka pilina a me nā mea
1. ʻO ka ʻōlelo maʻamau, e like me nā ʻano pili like ʻole, loaʻa nā ʻano ʻano flange o nā ʻūhā lele, ke ʻano wafer, a me ke ʻano lug, a hōʻike ʻia nā ʻano pili i ke kiʻi.No kēlā me kēia ʻano pili, aia nā ʻokoʻa maʻalahi e like me nā ʻano like ʻole, e like me ka wafer butterfly valve, aia nā Zhongfa Valve i nā ʻāpana maʻamau.
2. E like me ka mea, nā mea maʻamau he ductile hao kino, carbon kila kino, kuhiliʻole kino kino, keleawe kino, a super duplex kino kino.
# 2ʻO nā ʻāpana valve butterfly--Puke Kiwi
ʻO ke ʻano o ka disc valve kekahi ʻokoʻa, pin disc, pinless disc, disc me ka rubber, Disc me Nylon, Electroplated Disc, a pēlā aku, ʻO ka mea maʻamau, koho ʻia ka disc valve e like me nā kūlana hana a me ke ʻano.
No ka disiki pinless, Aia kahi ma waena a me ka hapalua hapalua, disc me ka ʻole o kahi pine e hoʻemi i ka pilikia o ka leakage, no ka Disc me kahi pine, aia paha ua ʻā a i ʻole ka ʻōpala ma hope o ka manawa lōʻihi. Media mai ka pine ma ka diski e hoʻokahe ai i ka lua kumu.Makemake mākou e koho i kahi disc pinless no kā mākou mea kūʻai.
# 3 Nā ʻāpana kiwi kīpē--Valve Spindle
ʻO ka spindle valve butterfly i kapa ʻia ʻo ke kumu, hoʻohana ʻia no ka hoʻouna ʻana, pili ʻia i ka actuator a i ʻole ka lima, ʻo ia ka mea e alakaʻi pololei ai i ka huli ʻana o ka pā valve, i mea e hoʻokō ai i ka hoʻololi ʻana a i ʻole ka hana hoʻoponopono.
1. Mai ka mea: ʻO ka mea spindle ka mea maʻamau i hana ʻia me ke kila kila a me ke kila kalapona, a ʻo kāna code: stainless steel (2cr13, 304, 316, 316L), carbon steel (35, 45, Q235).
2. Mai ke kaila: butterfly valve ma ke kumu (hema) a butterfly valve double half shaft ('ākau).
a: Ma ke ʻano o ke kumu kūʻai: ʻoi aku ka maikaʻi o ka hapalua hapalua ʻoi aku ka maikaʻi ma mua o ka through-shaft.
b: Ma ke ʻano o ka hoʻohana ʻana: hiki ke hana i ka hapalua hapalua ʻelua ma mua o DN300, a hiki i ke kumu ma waena ke hana iā DN800.
c: Hiki ke hoʻohana ʻia nā mea hoʻopili ma waena o ka lāʻau ma luna o nā kiwi pepeke i hoʻopaʻa ʻia me ka haʻahaʻa haʻahaʻa.Hiki ke hoʻohana ʻia i ʻelua mau pahu lele semi-shaft, a ʻoi aku ka kiʻekiʻe o ka ʻōpala.
d: Hui: ma waena o ka shaft me ka pine ʻole ke ʻano kumu i ka hoʻolālā ʻana, ka hoʻolālā maʻalahi, ka hoʻoili ʻana i ka shaft, nā pilikia hana ʻelua hapalua-shaft, maʻamau i hoʻokaʻawale ʻia i ka ʻaoʻao luna, a me ke kumu lalo.
# 4 Nā ʻāpana kiwi kīpē--Noho kiwi
Hiki ke hoʻokaʻawale ʻia ka noho lāʻau o ka pahu paʻa paʻa paʻa i ka noho hoʻopaʻa hope a me ka noho hoʻopaʻa hope, a ʻo ka noho o ka pahu paʻa paʻa paʻa paʻa ka nui o ke sila pono a me ka sila multi-level.
ʻO ka ʻokoʻa ma waena o kahi noho kaʻa paʻa paʻa a me kahi noho ʻōpala palupalu o ka valve butterfly: ua kaomi ʻia ka noho paʻa paʻa ma ke kino valve me nā abrasives, ʻaʻole hiki ke hoʻololi iā ia iho a koi i kahi flange kūikawā no ka valve butterfly. ;hana ʻia ka noho ʻūlū palupalu e ke kumu hoʻohālike, hiki ke hoʻololi iā ia iho a hiki ke hoʻohana ʻia me kahi flange ʻaʻole kūikawā no ka valve butterfly.
Ma ke ʻano o ke ola lawelawe o ka noho lāʻau, ʻoi aku ka lōʻihi o ke ola lawelawe o ka noho hope palupalu ma mua o ka noho hope paʻakikī, ʻo ia ka hale ākea ākea.ʻO ke kaʻina hana kiwi lōʻihi ka hoʻohana ʻana i ke kaʻina hoʻopau noho.Hoʻopau ka leaka ʻana o ke kumu noho kiwi ma hope o ke kahe ʻana o ka wai noho hope i waho o ke ʻano leakage kino.Akā ʻaʻole ʻike ʻia ke kua palupalu i kēia kūlana.
# 5 Nā ʻāpana kīpē kupu--paʻa ʻili
aia nā sila palupalu a me ka sila paʻakikī,ʻO ke koho o nā mea hoʻopaʻa paʻa paʻa:
1, Rubber (me ka butadiene rubber, EPDM rubber, etc.), i hoʻohana nui ʻia i nā paipu haʻahaʻa haʻahaʻa ma luna o ka aila a me ka wai.
2、Plastic (PTFE, nylon, a me nā mea ʻē aʻe), ʻoi aku no ka corrosive media i ka pipeline.
ʻO ke ʻano hana: lima, turbo, uila, pneumatic, hydraulic
Ke koho ʻana i nā mea sila paʻakikī:
1, Copper alloy (no nā puʻu haʻahaʻa haʻahaʻa)
2、Kōmeʻa kila kila (no ke kiʻekiʻe a me ka maʻamau kaomi kiwikā)
3、Stellite alloy (no ke kiʻekiʻe wela a me ke kiʻekiʻe-press valves ikaika corrosive kiwikā)
4、Nikikeli i hoʻopaʻa ʻia (no ka corrosive media)
# 6 Nā ʻāpana kīwī pēpē--Operation Actuator
Hoʻohana maʻamau ʻia nā kīwaha Butterfly i kēia, Lever Hand, Worm Gear, Pneumatic Actuator.
Hana ʻia nā lepa lima me ka ʻoʻoleʻa, mālama ʻia me ke kemika, a me ka pauda.Loaʻa i ka lima lima ka lima a me ka lever interlocking, He kūpono ia no DN40-DN250.
He kūpono ke kāʻei ilo no nā valve lele nui.Hoʻohana maʻamau ka pahu pahu worm no nā nui nui ma mua o DN250, aia nō nā pahu turbine ʻelua a me ʻekolu.
Hoʻokaʻawale ʻia nā mea hoʻokele pneumatic i ʻelua mau ʻāpana, hoʻokahi-hana a me ʻelua-hana pneumatic actuators.
Hiki ke hoʻokaʻawale ʻia nā mea hoʻokele uila i nā ʻano huli nui a me nā ʻano ʻāpana.ʻOi aku ka nui o ka huli ʻana ma mua o 360° no ka wehe ʻana a pani ʻana i ka valve aʻo ka huli ʻana o ke ʻano ʻāpana-huli ma ke ʻano maʻamau 90° e wehe a pani i ka pahu.
A laila, e nānā kākou pehea e hoʻokomo pū ai i nā ʻāpana valve butterfly
