A kiwikā pepekehe mea hoʻokele wai. Hoʻohana ia i kahi wili 1/4 e kāohi i ke kahe o nā media i nā kaʻina hana like ʻole. He mea nui ka ʻike ʻana i nā mea a me nā hana o nā ʻāpana. Kōkua ia i ke koho ʻana i ka valve kūpono no kahi hoʻohana kikoʻī. Loaʻa i kēlā me kēia ʻāpana, mai ke kino valve a i ke kumu valve, kahi hana kikoʻī. Hana ʻia lākou me nā mea kūpono no ka noi. He kuleana koʻikoʻi ko lākou āpau i ka hōʻoia ʻana i ka hana pono a me ka mālama ʻana. Hiki i ka hoʻomaopopo pono ʻana i kēia mau ʻāpana ke hoʻomaikaʻi i ka hana o ka ʻōnaehana a me ke ola lawelawe. Hoʻohana ʻia nā valves butterfly ma nā ʻano he nui ma muli o ko lākou versatility. ʻO nā ʻoihana e like me ka mālama ʻana i ka wai, ka hana kemika, a me ka meaʻai a me ka mea inu e hoʻohana i kēia mau valves. Hiki i nā valves butterfly ke lawelawe i nā kaomi a me nā mahana like ʻole. No laila, kūpono lākou i nā wahi kiʻekiʻe a me nā wahi haʻahaʻa. Eia kekahi, ʻo ke kumukūʻai haʻahaʻa a me ka maʻalahi o ke kau ʻana e hoʻokaʻawale iā ia i waena o nā valves he nui.
1. Inoa ʻĀpana o ka Pāpale Pepeiao: Kino Pāpale
He pūpū ke kino o ka valve pepeke. Kākoʻo ia i ka disc valve, ka noho, ke kumu, a me ka mea hoʻāla. ʻO kakino kiwikā pepekehoʻohana ʻia e hoʻopili i ka pipeline e mālama i ka valve ma kona wahi. Eia kekahi, pono ke kino valve e kū i nā kaomi a me nā kūlana like ʻole. No laila, he mea koʻikoʻi kona hoʻolālā no ka hana.
Mea kino kiwikā
ʻO ke ʻano o ke kino kiwikā e pili ana i ka paipu a me nā mea hana. Pili nō hoʻi ia i ke kaiapuni.
Eia nā mea i hoʻohana pinepine ʻia.
-Hao hao, ke ʻano kiwikā pepeke metala makepono loa. Loaʻa iā ia ke kūpaʻa maikaʻi i ka ʻaʻahu ʻana.
-Hao hao, i hoʻohālikelike ʻia me ka hao i hoʻolei ʻia, ʻoi aku ka ikaika, ke kūpaʻa i ka ʻaʻahu a me ka ductility maikaʻi. No laila kūpono ia no nā noi ʻoihana maʻamau.
-Kila kohu ʻole, he kūpaʻa maikaʻi loa a me ke kūpaʻa i ka pala. ʻOi aku ka maikaʻi no nā wai ʻino a me nā hoʻohana hoʻomaʻemaʻe.
-WCB,me kona paʻakikī a me ka ikaika kiʻekiʻe, kūpono ia no nā noi kiʻekiʻe-kaomi, wela kiʻekiʻe. A hiki ke hoʻoheheʻe ʻia.
2. Inoa ʻĀpana o ka Pāpale Pepeiao: Pāpale Valve
ʻO kapā kiwikā pepekeAia ma waenakonu o ke kino valve a hoʻohuli e wehe a pani paha i ka valve butterfly. Aia ka mea i ka pilina pololei me ke wai. No laila, pono e koho ʻia ma muli o nā waiwai o ka medium. ʻO nā mea maʻamau e komo pū me ka sphere nickel plating, nylon, rubber, stainless steel, a me ka alumini keleawe. Hiki i ka hoʻolālā lahilahi o ka disc valve ke hōʻemi i ke kū'ē ʻana o ke kahe, no laila e mālama i ka ikehu a hoʻomaikaʻi i ka pono o ka valve butterfly.
nā ʻano diski valve.
ʻAno diski valve: Aia kekahi mau ʻano diski valve no nā noi like ʻole.
-Kīwila valve concentricua kūlike me ke kikowaena o ke kino valve. He maʻalahi a kūpono hoʻi ke kumukūʻai.
-ʻO ka pāpaʻi kiwikā eccentric pāluahe ʻāpana laholio i hoʻokomo ʻia ma ka lihi o ka pā valve. Hiki iā ia ke hoʻomaikaʻi i ka hana sila.
ʻO ka disc eccentric ʻekoluhe metala. ʻOi aku ka maikaʻi o ke sila ʻana a emi ka ʻaʻahu ʻana, no laila maikaʻi ia no nā wahi me ke kaomi kiʻekiʻe.
3. Inoa ʻĀpana o ka Pāpale Pepeiao: Kumu
Hoʻohui ke kumu i ka mea hoʻomaka pahu disc. Hoʻoili ia i ka wili a me ka ikaika e pono ai e wehe a pani paha i ka valve butterfly. He kuleana koʻikoʻi kēia ʻāpana i ka hana mechanical o ka valve butterfly. Pono ke kumu e kū i ka nui o ka torque a me ke kaumaha i ka wā o ka hana. No laila, kiʻekiʻe nā koi mea e pono ai.
ʻO ka mea kumu valve
Hana pinepine ʻia ke koʻokoʻo me nā mea ikaika, e like me ke kila kila a me ka alumini keleawe.
-Kila kohu ʻolehe ikaika a kūpaʻa i ka pala.
-Keleawe aluminikakū'ē maika'i loa ia. Hō'oia'i'o lākou i ka hilina'i lō'ihi.
-Nā mea hana ʻē aʻehiki ke hoʻokomo i ke kila kalapona a i ʻole nā mea hoʻohui. Ua koho ʻia lākou no nā koi hana kikoʻī.
4. Inoa ʻĀpana o ka Pāpale Pepeiao: Noho
Hoʻokumu ka noho i loko o ka valve butterfly i kahi sila ma waena o ka disc a me ke kino valve. Ke pani ʻia ka valve, ʻomi ka disc i ka noho. Pale kēia i ka liki ʻana a mālama i ka ʻōnaehana pipeline.
ʻO kanoho kiwikā pepekepono e kū i nā ʻano kaomi a me nā mahana like ʻole. ʻO ke koho ʻana o ka mea noho e pili ana i ka noi kikoʻī. ʻO ka laholio, silicone, Teflon a me nā elastomers ʻē aʻe nā koho maʻamau.
Nā ʻano noho valve
Aia kekahi mau ʻano noho e hoʻokō ai i nā noi like ʻole. ʻO nā ʻano maʻamau:
-Nā noho kiwikā palupaluHana ʻia me ka laholio a i ʻole Teflon, he palupalu a paʻa hoʻi. He kūpono kēia mau noho no nā noi haʻahaʻa haʻahaʻa, mahana maʻamau e pono ai ka pani paʻa.
-ʻO nā noho kiwikā hao a pau: hana ʻia me nā metala, e like me ke kila kila. Hiki iā lākou ke kū i nā mahana kiʻekiʻe a me nā kaomi. He kūpono kēia mau noho valve no nā wahi koi e pono ai ke kūpaʻa.
-Nā noho valve multi-layerHana 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, hoʻokō kēia noho multi-layer i kahi kaulike ma waena o ka maʻalahi a me ka ikaika. ʻO kēia mau noho valve no nā noi sila hana kiʻekiʻe. Hiki iā lākou ke sila ʻoiai ke ʻaʻahu ʻia.
5. Mea hoʻoikaika
ʻO ka actuator ka mīkini e hoʻokele i ka valve butterfly. Hoʻohuli ia i ka papa valve e wehe a pani paha i ke kahe. Hiki i ka actuator ke manual (lima a i ʻole ka worm gear) a i ʻole automatic (pneumatic, uila, a hydraulic paha).
Nā ʻano a me nā mea hana
-ʻAuʻau:Hana ʻia me ke kila a i ʻole ka hao i hoʻolei ʻia, kūpono no nā kiwikā pulelehua o DN≤250.
-Mea hana no nā ilo:Kūpono no nā kiwikā pepeke o kēlā me kēia ʻano, mālama hana a me ke kumu kūʻai haʻahaʻa. Hiki i nā pahu kia ke hāʻawi i kahi pono mechanical. Hoʻomaʻalahi lākou i ka hoʻohana ʻana i nā kiwikā nui a kiʻekiʻe paha.
- Nā mea hoʻoikaika pneumatic:e hoʻohana i ka ea i hoʻopaʻa ʻia e hoʻokele i nā kiwikā. Hana pinepine ʻia lākou me ka alumini a i ʻole ke kila.
- Nā mea hoʻoikaika uila:hoʻohana i nā motika uila a ua hoʻokomo ʻia i loko o nā hale i hana ʻia me nā mea e like me ka alumini a i ʻole ke kila kila. Aia nā ʻano hoʻohui a me nā ʻano akamai. Hiki ke koho ʻia nā poʻo uila pale wai a me ka pahū no nā wahi kūikawā.
Nā mea hoʻoikaika hydraulic:e hoʻohana i ka ʻaila hydraulic e hoʻokele i nā kiwikā pepeke. Hana ʻia ko lākou mau ʻāpana i ke kila a i ʻole nā mea ikaika ʻē aʻe. Ua māhele ʻia i nā poʻo pneumatic hana hoʻokahi a me nā poʻo pneumatic hana pālua.
6. Nā Bushings
Kākoʻo a hōʻemi nā bushings i ka friction ma waena o nā ʻāpana e neʻe ana, e like me nā kumu valve a me nā kino. Hōʻoiaʻiʻo lākou i ka hana maʻalahi.
Nā Mea Hana
- PTFE (Teflon):haʻahaʻa haʻalulu a me ke kūpaʻa kemika maikaʻi.
- Keleawe:ikaika kiʻekiʻe a me ke kūpaʻa maikaʻi o ka ʻaʻahu.
7. Nā Gaskets a me nā O-rings
He mau mea sila nā Gaskets a me nā O-rings. Pale lākou i ka liki ʻana ma waena o nā ʻāpana valve a ma waena o nā valves a me nā pipelines.
Nā Mea Hana
- EPDM:hoʻohana pinepine ʻia i nā hana wai a me ka mahu.
- NBR:kūpono no nā hana ʻaila a me nā wahie.
- PTFE:Ke kūpaʻa kemika kiʻekiʻe, hoʻohana ʻia i nā noi kemika hoʻouka kaua.
- Viton:Ua ʻike ʻia no kona kūpaʻa ʻana i nā mahana kiʻekiʻe a me nā kemika hoʻouka kaua.
8. Nā ʻūmiʻi
Hoʻopaʻa pū nā ʻūmiʻi i nā ʻāpana o ka valve butterfly. Hōʻoiaʻiʻo lākou i ka ikaika o ka valve a pale i ka leaka.
Nā Mea Hana
- Kila kohu ʻole:Makemake ʻia no kona kūpaʻa i ka pala a me ka ikaika.
- Ke kila kalapona:Hoʻohana ʻia i nā wahi ʻino ʻole.
9. Nā pine
Hoʻohui nā pine i ka diski i ke kumu, e ʻae ana i ka neʻe ʻana o ka wili maʻalahi.
Nā Mea Hana
- Kila kohu ʻole:Ke kūpaʻa i ka palaho a me ka ikaika kiʻekiʻe.
- Keleawe:ʻO ke kūpaʻa o ka ʻaʻahu 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 Hana
- Ke kila:Ikaika kiʻekiʻe a me ka paʻakikī.
- Alumini:Kūpono no nā hana māmā.
11. Nā uhi a me nā uhi
Mālama nā liners a me nā uhi i ke kino valve a me nā ʻāpana mai ka pala, ka ʻino, a me ke komo ʻana.
- Nā uhi laholio:E like me EPDM, NBR, a i ʻole neoprene, i hoʻohana ʻia i nā noi corrosive a abrasive paha.
- Uhi PTFE:ke kūpaʻa kemika a me ka haʻalulu haʻahaʻa.
12. Nā hōʻailona kūlana
Hōʻike ka hōʻailona kūlana i ke kūlana hāmama a pani ʻia paha o ka valve. Kōkua kēia i nā ʻōnaehana mamao a i ʻole nā ʻōnaehana hana ponoʻī e nānā i ke kūlana o ka valve.
Nā ʻano
- Mekanika:he mea hōʻike mechanical maʻalahi i hoʻopili ʻia i ke kumu valve a i ʻole ka actuator.
- Uila:he mea ʻike
13. Hopena
ʻO nā ʻāpana i helu ʻia ma luna nei e hana i kahi kiwikā pepeke piha. ʻO nā mea like ʻole i hoʻohana ʻia no kēlā me kēia ʻāpana e hoʻoholo ai i ka hope loawahi hanao kēia kiwikā pulelehua.
Inā ʻino ke kaiapuni o waho, pono e hoʻohana ʻia nā kino valve kiʻekiʻe. Inā ʻoi loa ka waena, pono e hoʻomaikaʻi ʻia ke ʻano o ka noho valve, ka disc valve, a me ke kumu valve.
