ʻO ke ʻano valve mea kanu kemika a me kahi hoʻohana (me ke ʻano efficacy)

ʻO ke ʻano valve mea kanu kemika a me kahi hoʻohana (me ke ʻano efficacy)

Ma hope o ka hana ʻia ʻana o nā ʻenekini mahu, i nā makahiki he iwakālua a kanakolu paha i hala, no ka pono o ka aila maʻemaʻe, nā mea kanu kemika, nā mea kanu mana, nā ʻoihana metallurgical, nā moku, nā mana nuklea, aerospace a me nā ʻāina ʻē aʻe, ua hōʻike maopopo ʻia nā mea ʻoi aku ka maikaʻi. no nā kiwikā, a me nā ʻano ʻano ʻano like ʻole o nā ʻano hana ʻenehana.Like valvee hoʻolauna i ke kahua hoʻohana a me ka pono o ka mea kanu kemika.

He ʻano valve mea kanu kemika a me ka hoʻohana ʻana

1. Hoʻokaʻawale e like me ka efficacy a me ke kahua noi

(1) wehe i ka pahu: ʻike ʻia ka ʻoki ʻoki ʻia ʻo ke kelepona kikohoʻe TELEVISION valve, a ʻo kona hopena ʻo ke komo ʻana a i ʻole ka wehe ʻana i ke kikowaena i loko o ka pipeline. Loaʻa i nā ʻoki ʻoki ʻia nā kīwaha honua, nā kīwaha honua, nā kiwi palaka, nā kiwi, nā kīwaha disc a me nā diaphragms.

(2) nānā valve: ʻike ʻia ka valve check he throttle valve a i ʻole check valve, ʻo kona hopena ke pale aku i ka waena o ka pipeline upstream. ʻO ka pauma Centrifugal hygroscopic off pump bottom valve no ka papa check valve.

(3) valve: ʻo ka hana o ka papa valve palekana e pale aku i ke kaomi hana o ka medium i ka pipeline a i ʻole nā ​​​​mea hana i ʻoi aku ka kiʻekiʻe ma mua o ka waiwai i kuhikuhi ʻia, i hiki ai ke hoʻokō i ka pahuhopu o ka palekana palekana.

(4) hoʻoponopono valve: hoʻoponopono i ka papa valve e pili ana i ka valve hoʻoponopono, hoʻokahi ala throttle valve a me ke kaomi hoʻoponopono valve, ʻo kona hopena e hoʻoponopono i ke kaomi hana o ka waena, ka holo holoʻokoʻa a me nā ʻekolu ʻē aʻe.

(5) separation valve: ʻo ka shunt valve category e loaʻa ana i nā ʻano ʻano like ʻole a me nā ʻāpana mahu, a me nā mea ʻē aʻe.

2. Hoʻokaʻawale ʻia e ka papa paona

(1) Vacuum valve: e pili ana i ka valve nona ka emi iho o ke kaomi o ka lewa ma'amau.

(2) Haʻahaʻa voltage valve: pili i ka paona papa PN ¡Ü 1.6mpa valve.

(3) puʻe puʻe haʻahaʻa: e pili ana i ke kaomi nominal PN he 2.5, 4.0, 6.4Mpa valve.

(4) High pressure valve: pili i ka valve me ke kaomi hana PN o 10 ~ 80Mpa.

(5) kiʻekiʻe kaomi valve: pili i ka valve o PN¡Ý100Mpa.

3. Hoʻokaʻawale e like me ka mahana hana

(1) low temperature valve: for medium operating temperature t (1) ha'aha'a wela wela: no ka wela wela t

(2) haʻahaʻa haʻahaʻa haʻahaʻa haʻahaʻa: waena wela hana -100¡æ¡Ü T ¡Ü-40¡æ valve.

(3) Puka wela maʻamau: ka wela hana maʻamau -40¡æ¡Ü T ¡Ü120¡æ valve.

(4) Medium wela valve: no ka mahana hana ma waena o 120¡æ

(5) kiʻekiʻe wela wela: no ka mea wela wela T >450¡æ kiwi.

4. Hoʻokaʻawale e like me ke ʻano hoʻolaha

(1) ʻAʻole ʻo ka valve aunoa ka ikaika o waho e hoʻolaha ai, akā me ka mana o ke kikowaena ponoʻī e hana i ke kūlana valve o ka valve. E like me ka valve, ka pahu hoʻoponopono kaomi, ka pahele mahu, ka pahu hoʻopaʻa, ka valve mana a me nā mea'ē aʻe.

(2) Ka hoʻokele mana hoʻokele: hiki ke hoʻohana i nā ʻano mana mana e hoʻolaha ai.

ʻO ka valve mana uila: e hilinaʻi ana i ka ʻenehana mana e hoʻolaha i ka valve.

Pneumatic valve: ka pahu i hoʻokele ʻia e ka hoʻoemi ʻana i ka ea.

Hydraulic valve: ka pahu i alakaʻi ʻia e ke kaomi o ka wai e like me ka ʻaila.

Eia kekahi, aia kekahi mau ʻāpana o nā ʻano o ka hoʻokele kaʻa i luna, e like me nā valve hoʻoponopono gas-electric.

(3) ʻO ka valve manual: pili ka valve manual i ka spindle, rocker, rod bar, sprocket chain, e nā kumuwaiwai kanaka e hoʻomalu i ka posture valve. Ke ʻano nui ka wehe ʻana a me ka pani ʻana o ka valve, hiki ke hoʻonohonoho ʻia ka huila a i ʻole ka mea hoʻemi ilo ma waena o ka spindle a me ka noho. Inā pono, hiki ke hoʻohana ʻia nā hui cardan a me nā shaft rotating no ka hana hoʻokō lōʻihi.

5, e like me ka helu anawaena nominal anawaena

(1) Li'ili'i anawaena valve: nominal anawaena DN¡Ü40mm valve.

(2) Medium diameter valve: nominal diameter DN o 50 ~ 300mm valve.

(3) Nui anawaena valve: nominal diameter valve DN o 350 ~ 1200mm valve.

6. Hoʻokaʻawale e like me ke ʻano o ka hale

(1) ke ʻano o ka valve: ʻo ka wehe a me ka pani pani ʻana (piston valve) e alakaʻi ʻia e ka noho ma ke koʻi o ka ʻīpuka paʻa kiʻekiʻe e hoʻoponopono i ka neʻe ʻana o ke kino;

(2) hoʻopili i ke ʻano o ka valve: ʻo ka wehe ʻana a me ka pani pani ʻana (globe valve) ua hoʻokuʻu ʻia e ka noho valve ma ka ʻaoʻao o ka axis kiʻekiʻe e hoʻopololei ana i ke kaomi kiʻekiʻe no ka hoʻoponopono ʻana i ka neʻe ʻana o ke kino;

(3) pahu pahu: wehe a pani ʻia nā ʻāpana (cone plug a pōpō paha) a puni kona axis rotation;

(4) kiwi wili: ʻo ka wehe a me ka pani pani (piston valve) pili paʻa a puni ke kumu ma waho o ka hoʻololi noho;

(5) ka lālani butterfly: ʻo ka wehe a me ka pani ʻana o nā ʻāpana (disk) e hoʻohuli paʻa a puni ka lāʻau paʻa paʻa i loko o ka pahu kiʻekiʻe kiʻekiʻe;

(6) Rotary plate pump line: ʻo ka wehe ʻana a me ka pani ʻana o nā ʻāpana e ʻōwili ʻia ana i ke ala o ke kahawai palekana bisector vertical.

7. Hoʻokaʻawale e like me ke ʻano pili

(1) Flanged pili valve: aia i loko o ke kino valve ke kaula a i ʻole ke kaula paipu, i hoʻopili ʻia me ka flange paipu.

(2) Flanged pili valve: aia i loko o ke kino valve ka flange plate, pili me ka pipeline flange.

(3) uila kuʻihao kuʻihao hookui kiwikā: i loko o ke kino kuʻihao uila kuʻihao kuʻihao kuʻihao, a me ka wili paipu pili.

(6) Wafer pili valve: ʻo ke ʻano hoʻohui e hoʻopili koke ʻia ai ka pahu a me nā laina paipu ma nā ʻaoʻao ʻelua me ka pōleʻa honua.

8, e like me ka mea kino valve

(1) Metal valve: ua hana ʻia ke kino valve a me nā ʻāpana ʻē aʻe i nā mea metala. E like me ka pahu hao puaʻa, ka pahu kila kalapona, ka pahu kila kila, ka pahu keleawe keleawe, ka pahū kōpili alumini, ka pahu alumini alumini, ka pahu titanium, ka pahu pahu Monel, etc.

(2) non-metallic valve: ʻo ke kino valve a me nā ʻāpana ʻē aʻe i hana ʻia i nā mea non-metallic. E like me ka pahu palaki, ka valve ceramic, ka valve lined, FRP anticorrosive valve, etc.

(3) mea metala valve kino lining valve: valve kino hiʻona hoʻolālā no ka mea metala, hale i loko kahi e pili ai me ka mea waena ka nui o ka uhi ʻana o ka ʻili, e like me ka mea hoʻolaha aila, ka pahu palaki, ka valve ceramic, etc.

ʻElua, efficacy mea kanu kemika

ʻAno wehe a pani: wehe a kamaʻilio paha i ka wai o ka wai i loko o ka paipu ac;

Keʻano hoʻololi: hoʻololi i ka holoʻokoʻa holoʻokoʻa a me ka holo wikiwiki i loko o ka paipu;

ʻAno pahu throttle: hana i ka wai e like me ka valve ma hope o ka hana ʻana i ke kaomi kinoea nui loa;

Nā ʻano ʻē aʻe: a. ka wehe 'akomi piha a me ka pani 'ana B. ka malama 'ana i ke kaomi hana 'ana C. ka paipu 'a'ai 'ana i ka mahu.
