Pehea e koho pono ai i ka valve i laweia mai

(Ka wehewehe hōʻuluʻulu manaʻo)ʻO nā pahu i lawe ʻia mai e pili ana i nā pahu mai nā ʻāina ʻē, ʻo ka nui o ʻEulopa, ʻAmelika a me Iapana.

ʻO nā pahu i lawe ʻia mai e pili ana i nā pahu mai nā ʻāina ʻē, ʻo ka nui o ʻEulopa, ʻAmelika a me Iapana. ʻO nā ʻano huahana o nā valves ka mea nui i lawe ʻia i nā kīpē pōleʻa i lawe ʻia mai, i lawe ʻia i nā kīwaha hoʻomaha, i lawe ʻia i nā kīwī hoʻoponopono, i lawe ʻia i nā kīwaha butterfly, i lawe ʻia mai nā puʻupuʻu hoʻohaʻahaʻa hoʻohaʻahaʻa, nā kiwi solenoid lawe ʻia, etc. , keʻano o ka pilina, keʻano hana, a me nā mea'ē aʻe. Pono e koho i ka valve kūpono e like me nā pono maoli a me nāʻano huahana.
1. ʻO nā hiʻohiʻona o ka valve i lawe ʻia mai nā hiʻohiʻona hoʻohana a me nā ʻano hana

1. E hoʻohana i nā hiʻohiʻona o nā valve i lawe ʻia mai

Hoʻoholo nā hiʻohiʻona hoʻohana i ka hana hoʻohana nui a me ka laulā o ka valve. ʻO nā hiʻohiʻona hoʻohana o ka valve ka: valve category (paʻa kaapuni valve, hoʻoponopono valve, palekana palekana, etc.); ʻano huahana (puka valve, globe valve, butterfly valve, ball valve, etc.); ʻO ka valve Material o nā ʻāpana nui (ke kino kiwi, ka pāpale, ka pahu pahu, ka disc valve, ka ʻili o ka sila); ʻano hoʻoili valve, etc.

2. Nā hiʻohiʻona hoʻolālā

ʻO nā hiʻohiʻona hoʻolālā e hoʻoholo i kekahi mau hiʻohiʻona o ka hoʻonohonoho valve, hoʻoponopono, mālama a me nā ʻano hana ʻē aʻe. ʻO nā hiʻohiʻona hoʻolālā e like me: ka lōʻihi o ke kūkulu ʻana a me ke kiʻekiʻe holoʻokoʻa o ka valve, ke ʻano pili me ka pipeline (pili flange, pili pili, pili pili, pili pili waho, pili hope welding, etc.); ke ʻano o ka ili hoʻopaʻa (ke apo inlay, apo threaded, surfacing, spray welding, valve body); ka hoʻokumu ʻana o ka valve stem (rooting rod, lifting rod), etc.

ʻO ka lua, nā ʻanuʻu e koho i ka valve

E wehewehe i ke kumu o ka valve i loko o nā mea hana a mea paha, a hoʻoholo i nā kūlana hana o ka valve: pili pono, kaomi hana, wela hana, etc.; no ka laʻana, inā makemake ʻoe e koho i kahi pahu pani LIT Kelemania, e hōʻoia i ka mahu ka waena, a ʻo ka loina hana ʻo 1.3Mpa, ʻo ka mahana hana he 200 ℃.

E hoʻoholo i ke anawaena inoa a me ke ʻano pili o ka pipeline i pili i ka valve: flange, thread, welding, etc.; no ka laʻana, koho i ka pahu komo komo a hōʻoia i ke ʻano o ka hoʻopili ʻana i flanged.

E hoʻoholo i ke ala e hana ai i ka valve: manual, electric, electromagnetic, pneumatic or hydraulic, electro-hydraulic linkage, etc.; no ka laʻana, koho ʻia ka pahu pani pani -

E hoʻoholo i nā mea o ka pūpū valve i koho ʻia a me nā ʻāpana o loko e like me ke ʻano, ke kaomi hana a me ka mahana hana o ka pipeline: ke kila kila, ke kila kalapona, ke kila kila, ke kila kila, ka waiʻawaʻawa-ke kila kūpaʻa, ka hao hina, ka hao malleable. , hao ductile, keleawe Alloy, etc.; e like me ka mea kila kila i koho ʻia no ka valve honua.

E koho i ke ʻano o ka valve: ka valve kaapuni paʻa, ka valve hoʻoponopono, ka valve palekana, etc.;

E hoʻoholo i ke ʻano o ka valve: ka valve puka, ka valve globe, ball valve, butterfly valve, throttle valve, safety valve, pressure reduced valve, steam trap, etc.;

E hoʻoholo i nā palena o ka valve: No nā valves 'akomi, e hoʻoholo mua i ke kū'ē kahe e'āponoʻia, ka hoʻokuʻuʻana i ka mana, ke kaomi hope, a me nā mea'ē aʻe e like me nā pono likeʻole, a laila e hoʻoholo i ke anawaena nominal o ka pipeline a me ke anawaena o ka puka noho valve;

E hoʻoholo i nā ʻāpana geometric o ka valve i koho ʻia: ka lōʻihi o ke kūkulu ʻana, ke ʻano o ka pili flange a me ka nui, ka nui o ke kiʻekiʻe o ka valve ma hope o ka wehe ʻana a me ka pani ʻana, ka hoʻohui ʻana i ka nui o ka puka bolt a me ka helu, ka nui o ka outline outline valve, etc.;

E hoʻohana i ka ʻike i loaʻa: nā papa inoa huahana valve, nā laʻana huahana valve, a pēlā aku e koho ai i nā huahana valve kūpono.

ʻO ke kolu, ke kumu no ke koho ʻana i nā valves

ʻO ke kumu, nā kūlana hana, a me nā ʻano kaohi o ka valve i koho ʻia;

ʻO ke ʻano o ke ʻano hana: ke kaomi hana, ka mahana hana, ka hana corrosion, inā he mau mea paʻa i loko, inā he mea ʻawaʻawa, inā he mea puhi ahi a pahū paha, ka viscosity o ka medium, etc.; no ka laʻana, inā makemake ʻoe e koho i ka valve solenoid i lawe ʻia mai LIT, ʻo ka medium Ma waho aʻe o ka pōʻaiapuni a me nā mea pahū, koho maʻamau ka pahū-proof solenoid valve; ʻO kekahi laʻana, ʻo ia ke koho ʻana i ka pahu pōpō o German Lit LIT. Aia nā ʻāpana paʻa i loko o ke kikowaena, a ua koho maʻamau ʻia ke ʻano V-like hard-sealed ball valve.

Nā mea e pono ai no nā hiʻohiʻona wai o ka valve: ke kahe o ke kahe, ka hoʻokuʻu ʻana, nā hiʻohiʻona kahe, ka pae sealing, etc.;

ʻO nā koi no nā ana hoʻokomo a me nā ana o waho: ke anawaena nominal, ke ʻano pili a me nā ana pili me ka pipeline, nā ana waho a i ʻole nā ​​palena kaumaha, etc.;

Nā koi hou aʻe no ka hilinaʻi o ka huahana valve, ke ola lawelawe, a me ka pahū - hōʻoia i ka hana o nā mea uila (e nānā i ke koho ʻana i nā ʻāpana: Inā e hoʻohana ʻia ka valve no nā kumu hoʻomalu, pono e hoʻoholo ʻia nā ʻāpana ʻē aʻe: ke ʻano hana, ka palena kiʻekiʻe a me ka liʻiliʻi. nā koi , ʻO ka hāʻule kaomi o ke kahe maʻamau, ka hāʻule o ke kaomi i ka wā e pani ai, ka palena kiʻekiʻe a me ka liʻiliʻi o ke kaomi inlet o ka valve).

E like me ka mea i ʻōlelo ʻia ma luna aʻe a me nā ʻanuʻu no ke koho ʻana i nā kiwi, pono e loaʻa ka ʻike kikoʻī o ke ʻano o loko o nā ʻano ʻano like ʻole i ke koho ʻana i nā kiwikā me ke kūpono a me ka pololei, i hiki ai ke hoʻoholo pololei i ka valve i makemake ʻia.

ʻO ka mana hope loa o ka pipeline ka valve. ʻO ka wehe ʻana a me ka pani ʻana o ka valve e hoʻomalu i ke ala kahe o ka waena ma ka pipeline. ʻO ke ʻano o ke ala kahe o ka valve e loaʻa i ka valve kekahi ʻano kahe. Pono e noʻonoʻo ʻia kēia i ke koho ʻana i ka valve kūpono loa no ka ʻōnaehana pipeline.
E hōʻuluʻulu a hōʻuluʻulu i kekahi mau mea nui o ke koho: e hoʻoholo i ka hana o ka valve e koho ai, e hōʻoia i ka mahana a me ke kaomi o ka waena, e hōʻoia i ka kahe kahe o ka valve a me ke anawaena e pono ai, e hōʻoia i ka mea o ka valve, a me ke ʻano hana;
