A lele lelehe mea hooponopono wai. Hoʻohana ʻo ia i ka huli ʻana o 1/4 e hoʻomalu i ke kahe o ka media ma nā ʻano hana like ʻole. He mea nui ka ʻike i nā mea hana a me nā hana o nā ʻāpana. Kōkua ia i ke koho ʻana i ka valve kūpono no kahi hoʻohana kikoʻī. ʻO kēlā me kēia mea, mai ke kino valve a hiki i ke kumu valve, he hana kūikawā. Hana ʻia lākou i nā mea kūpono no ka noi. He kuleana koʻikoʻi lākou a pau i ka hōʻoia ʻana i ka hana kūpono a me ka mālama ʻana. Hiki i ka ʻike kūpono o kēia mau ʻāpana ke hoʻomaikaʻi i ka hana ʻōnaehana a me ke ola lawelawe. Hoʻohana ʻia nā kīwaha Butterfly ma nā kula he nui ma muli o kā lākou versatility. Hoʻohana nā ʻoihana e like me ka mālama wai, ka hana kemika, a me ka meaʻai a me ka mea inu i kēia mau valve. Hiki i nā kiwi kīpē ke hoʻopaʻa i nā pilikia a me nā mahana like ʻole. No laila, kūpono lākou i nā kaiapuni kiʻekiʻe a haʻahaʻa. Eia kekahi, ʻo ke kumu kūʻai haʻahaʻa a me ka maʻalahi o ka hoʻonohonoho ʻana e kū i waena o nā valves he nui.
1. ʻAha ʻĀpana Papa inoa: kino kino
He pūpū ke kino o ka valve lele. Kākoʻo ia i ka disc valve, noho, stem, a me actuator. ʻO kakino kīpē lelehoʻohana ʻia e hoʻopili i ka pipeline e mālama i ka valve ma kona wahi. Eia kekahi, pono e kū i ke kino valve i nā ʻano paʻi a me nā kūlana. No laila, koʻikoʻi kona hoʻolālā i ka hana.
Mea kino kiwi
Pili ke kino o ka valve i ka pipeline a me ka media. Ma muli o ke kaiapuni.
ʻO nā mea maʻamau i hoʻohana ʻia ma lalo nei.
-Ka hao hao, ʻo ke ʻano haʻahaʻa loa o ka valve butterfly metal. Loaʻa iā ia ke kūpaʻa ʻaʻahu maikaʻi.
-Ka hao hao, i hoʻohālikelike ʻia me ka hao hoʻolei, ʻoi aku ka maikaʻi o ka ikaika, ke kūpaʻa a ʻoi aku ka maikaʻi o ka ductility. No laila ua kūpono ia no nā noi ʻoihana maʻamau.
-Kila kohu ʻole, he kūpaʻa nui a me ka pale ʻana i ka corrosion. ʻOi aku ka maikaʻi no nā wai corrosive a me ka hoʻohana maʻemaʻe.
-WCB,me kona paʻakikī kiʻekiʻe a me ka ikaika, kūpono ia no nā noi kiʻekiʻe, kiʻekiʻe-mehana. A hiki ke weldable.
2. Inoa Mahele o ka ʻĀpana Pepa: Disc
ʻO kadisc valve leleaia i waenakonu o ke kino kiwi a hoʻololi e wehe a pani paha i ka valve lele. Pili pololei ka mea me ka wai. No laila, pono ke koho ʻia e pili ana i nā waiwai o ka medium. ʻO nā mea maʻamau e pili ana i ka sphere nickel plating, nylon, rubber, stainless steel, a me ke keleawe aluminika. ʻO ka hoʻolālā lahilahi o ka disc valve hiki ke hōʻemi i ka pale ʻana i ke kahe, a laila e mālama i ka ikehu a hoʻomaikaʻi i ka pono o ka valve butterfly.
nā ʻano disc valve.
Ke ʻano disc valve: Nui nā ʻano disc valve no nā noi like ʻole.
-Vila kīpē concentricaligned me ke kikowaena o ke kino valve. He mea maʻalahi a me ke kumu kūʻai.
-Palua eccentric valve discua hoʻokomo ʻia kahi ʻōpala ma ka lihi o ka pā kiwi. Hiki iā ia ke hoʻomaikaʻi i ka hana sila.
ʻO ka disc eccentric triplehe metala. Hoʻopaʻa maikaʻi a ʻaʻahu liʻiliʻi, no laila maikaʻi ia no nā kaiapuni kiʻekiʻe.
3. Ka inoa o ka ʻāpana Butterfly: Stem
Hoʻopili ke kumu i ka mea hoʻokani pahu disc. Hāʻawi ia i ka ʻōwili a me ka ikaika e pono ai e wehe a pani paha i ka valve butterfly. He koʻikoʻi ko kēia ʻāpana i ka hana mechanical o ka valve butterfly. Pono ke kumu e pale i ka nui o ka torque a me ke kaumaha i ka wā o ka hana. No laila, kiʻekiʻe nā koi mea pono.
ʻO ke kumu pahu valve
Hana ʻia ke kumu i nā mea ikaika, e like me ke kila kila a me ke keleawe alumini.
-Kila kohu ʻoleikaika a kū i ka ʻino.
-Ke keleawe aluminipale maikaʻi loa. Hoʻopaʻa lākou i ka hilinaʻi lōʻihi.
-ʻO nā mea'ē aʻehiki ke hoʻokomo i ke kila kalapona a i ʻole nā mea hao. Ua koho ʻia lākou no nā koi pono hana.
4. Butterfly Valve Part Name: Noho
ʻO ka noho i loko o ka valve butterfly he sila ma waena o ka disc a me ke kino valve. Ke pani ʻia ka valve, kaomi ka disc i ka noho. Mālama kēia i ka leakage a mālama pono i ka ʻōnaehana pipeline.
ʻO kanoho kiwi lele lelepono e kū i nā ʻano pilikia a me nā mahana. ʻO ke koho o nā mea noho e pili ana i ka noi kikoʻī. ʻO ka Rubber, silicone, Teflon a me nā elastomers ʻē aʻe nā koho maʻamau.
Nā ʻano noho kiwi
Nui nā ʻano noho e hālāwai me nā noi like ʻole. ʻO nā ʻano maʻamau:
-Nā noho valve palupalu: Hana ʻia me ka ʻōpala a i ʻole Teflon, hiki ke maʻalahi a paʻa. He kūpono kēia mau noho no ka haʻahaʻa haʻahaʻa, nā mea wela maʻamau e pono ai ke pani paʻa.
-ʻO nā noho valve metala āpau: ua hana ʻia me nā metala, e like me ke kila kila. Hiki iā lākou ke pale i nā wela kiʻekiʻe a me nā pilikia. He kūpono kēia mau noho valve no nā kaiapuni koi e pono ai ka lōʻihi.
-ʻO nā noho valve multi-layer: Hana ʻia me ka graphite a me ka metala i hoʻopaʻa ʻia i ka manawa hoʻokahi. Hoʻohui lākou i nā ʻano o nā noho valve palupalu a me nā noho valve metala. No laila, Loaʻa i kēia noho multi-layer i kahi kaulike ma waena o ka maʻalahi a me ka ikaika. ʻO kēia mau noho valve no nā hana hoʻopaʻa kiʻekiʻe. Hiki iā lākou ke sila i ka wā e ʻaʻahu ʻia ai.
5. Mea hoʻokele
ʻO ka actuator ka mīkini e hoʻohana ai i ka valve butterfly. Hoʻohuli ia i ka pā valve e wehe a pani i ke kahe. Hiki i ka mea hoʻokele ke manual (lima a i ʻole nā mea hana worm) a i ʻole (pneumatic, uila, a hydraulic paha).
Nā ʻano a me nā mea
-Kalima:Hana ʻia me ke kila a i ʻole ka hao, kūpono no nā kiwi lele o DN≤250.
- ʻAi ilo:He kūpono no nā kiwi lele o kēlā me kēia caliber, mālama hana a me ke kumu kūʻai haʻahaʻa. Hiki i nā pahu pahu ke hāʻawi i kahi pono mechanical. Hiki iā lākou ke maʻalahi i ka hoʻohana ʻana i nā valve nui a i ʻole kiʻekiʻe.
- Nā mea hana pneumatic:e hoʻohana i ka ea compressed e hoʻohana i nā kiwi. Hana ʻia lākou i ka alumini a i ʻole ke kila.
- Nā mea hana uila:hoʻohana i nā kaʻa uila a hoʻokomo ʻia i loko o nā hale i hana ʻia me nā mea e like me ke alumini a i ʻole ke kila kila. Aia nā ʻano integral a naʻauao. Hiki ke koho ʻia nā poʻo uila pale wai a pahū no nā kaiapuni kūikawā.
Nā mea hana hydraulic:e hoʻohana i ka aila hydraulic e hana i nā kiwi lele. Hana ʻia kā lākou mau ʻāpana i ke kila a i ʻole nā mea ikaika ʻē aʻe. Hoʻokaʻawale ʻia ia i nā poʻo pneumatic hana hoʻokahi a me ʻelua.
6. Nā lāʻau ulu
Kākoʻo a hoʻemi ʻo Bushings i ka hakakā ma waena o nā ʻāpana e neʻe ana, e like me nā ʻōpala a me nā kino. Hoʻopaʻa lākou i ka hana maʻalahi.
Nā mea waiwai
- PTFE (Teflon):haʻahaʻa friction a maikaʻi kemika kū'ē.
- keleawe:ka ikaika kiʻekiʻe a me ke kūpaʻa maikaʻi.
7. ʻO nā Gaskets a me nā O-rings
ʻO nā Gaskets a me nā O-rings nā mea hoʻopaʻa. Pale lākou i ka leakage ma waena o nā ʻāpana valve a ma waena o nā valve a me nā pipeline.
Nā mea waiwai
- EPDM:hoʻohana mau ʻia i ka wai a me ka mahu.
- NBR:kūpono no ka aila a me ka wahie.
- PTFE:ʻO ke kūpaʻa kemika kiʻekiʻe, hoʻohana ʻia i nā noi kemika koʻikoʻi.
- Viton:ʻIke ʻia no kona kūpaʻa ʻana i nā wela kiʻekiʻe a me nā kemika hoʻopaʻapaʻa.
8. Nā kī
Hoʻopaʻa pū ʻia nā ʻāpana o ka valve butterfly. Hoʻomaopopo lākou i ka ikaika a me ka leak-proof ka valve.
Nā mea waiwai
- Kila kohu ʻole:Makemake ʻia no kona kūpaʻa ʻana a me ka ikaika.
- Ke kila kalapona:Hoʻohana ʻia i nā wahi ʻino ʻole.
9. Nā pine
Hoʻopili nā pine i ka diski i ke kumu, e ʻae ai i ka neʻe ʻana o ka ʻoni.
Nā mea waiwai
- Kila kohu ʻole:ʻO ke kūpaʻa kino a me ka ikaika kiʻekiʻe.
- keleawe:E hoʻohana i ke kūpaʻa a me ka machinability maikaʻi.
10. Nā iwi ʻaoʻao
Hāʻawi nā iwi ʻaoʻao i ke kākoʻo kūkulu hou i ka diski. Hiki iā lākou ke pale i ka deformation ma lalo o ke kaomi.
Nā mea waiwai
- Ke kila:Ka ikaika kiʻekiʻe a me ka ʻoʻoleʻa.
- Aluminum:Kūpono no nā noi māmā.
11. Lining a me ka uhi
Mālama nā laina laina a me nā uhi i ke kino valve a me nā ʻāpana mai ka ʻinoʻino, erosion, a me ka ʻaʻahu.
- Nā ʻili Rubber:E like me EPDM, NBR, a i ʻole neoprene, i hoʻohana ʻia i nā noi corrosive a i ʻole abrasive.
- ka uhi PTFE:pale kemika a me ka haʻahaʻa haʻahaʻa.
12. Nā hōʻailona kūlana
Hōʻike ka hōʻailona kūlana i ka wehe a pani ʻia paha o ka valve. Kōkua kēia i nā ʻōnaehana mamao a i ʻole nā polokalamu e nānā i ke kūlana valve.
Nā ʻano
- Mechanical:kahi hōʻailona mechanical maʻalahi i hoʻopili ʻia i ke kumu valve a i ʻole ka mea hana.
- Uila:he mea ike
