Nā ʻanuʻu koho valve:
1. E wehewehe i ka hoʻohana ʻana i ka valve i loko o nā mea hana a i ʻole nā mea hana, e hoʻoholo i nā kūlana hana o ka valve: kūpono kūpono, kaomi hana, ka mahana hana a pēlā aku.
2. E hoʻoholo i ke anawaena inoa a me ke ʻano pili o ka paipu e pili ana me ka valve: flange, thread, welding, jacket, fast-fixing, etc.
3. E hoʻoholo i ke ala e hana ai i ka valve: manual, electric, electromagnetic, pneumatic or hydraulic, electrical or hydraulic linkage, etc.
4. E like me ka mea i lawe ʻia e ka pipeline, ke kaomi hana a me ka mahana hana, ua koho ʻia nā mea o ka pūpū valve a me nā ʻāpana i loko: hao hina hina, hao malleable, hao nodular, hao kalapona, ke kila kila, ke kila kuhiliʻole. , hui keleawe, etc.
5. E koho i nā 'ano o ka valves: closed-circuit valves, regulatoring valves, safety valves, etc.
6. E hoʻoholo i ke ʻano o nā kiwi: nā ʻīpuka ʻīpuka, nā kīwaha honua, nā kiwi pōpō, nā kīwaha butterfly, nā kīwī throttle, nā kīwaha palekana, nā puʻupuʻu hoʻoluhi kaomi, nā pahele mahu, etc.
7. E hoʻoholo i nā palena o nā valves: No nā valves aunoa, ua hoʻoholo muaʻia ke kū'ēʻana o ke kahe, ka hoʻokuʻuʻana, ke kua, a me nā mea'ē aʻe, a laila ua hoʻoholoʻia ke anawaena inoa o ka pipeline a me ke anawaena o ka puka noho valve.
8. E hoʻoholo i nā palena geometric o ka valve i koho ʻia: ka lōʻihi o ke kūkulu ʻana, ke ʻano o ka pili flange a me ka nui, ke kuhikuhi kiʻekiʻe o ka valve ma hope o ka wehe ʻana a me ka pani ʻana, ka nui o ka puka bolt a me ka helu o nā pilina, ka nui o ke ʻano o ka valve holoʻokoʻa, etc.
9.E hoʻohana i ka ʻike i loaʻa: Valve product catalog, valve product samples, etc. e koho i nā huahana valve kūpono.
Kumu koho valve:
1. ʻO ka hoʻohana, nā kūlana hana a me ke ʻano mana o ka valve i koho ʻia.
2. Nā waiwai o ka mea hana: ke kaomi hana, ka mahana hana, ka hana ʻino, inā paha i loko o nā ʻāpana paʻa, inā he mea ʻawaʻawa ka mea, inā he mea puhi, pahū, ʻano viscosity a pēlā aku.
3. Nā mea e pono ai no nā hiʻohiʻona o ka wai valve: ke kahe ʻana o ke kahe, ka hoʻokuʻu ʻana, nā ʻano kahe, ka pae sealing, etc.
4. Ka nui o ka hoʻokomo ʻana a me ka nui o ka outline e pono ai: nominal diameter, mode pili me ka pipeline a me ka nui pili, outline dimension a i ʻole ka palena kaumaha, etc.
5. Nā koi hou aku no ka hilinaʻi o nā huahana valve, ke ola lawelawe a me ka hana pahū-hōʻoia o nā mea uila. (Pono e noʻonoʻo i ke koho ʻana i nā ʻāpana: inā e hoʻohana ʻia ka valve no nā manaʻo hoʻomalu, pono e hoʻoholo ʻia nā ʻāpana ʻē aʻe e like me kēia: ke ʻano hana, ka palena kiʻekiʻe a me ka liʻiliʻi o ka kahe ʻana, ka hāʻule o ke kahe maʻamau, ka hāʻule ʻana o ke kaomi i ka pani ʻana, ka nui a me ka palena iki o ka pahu komo.)
E like me ka mea i ʻōlelo ʻia ma luna a me nā ʻanuʻu no ke koho ʻana i nā valves, i ke koho ʻana i nā valves me ke kūpono a me ka pololei, pono e loaʻa kahi ʻike kikoʻī o ke ʻano o loko o nā ʻano ʻano like ʻole o nā valves i mea e hana ai i ke koho kūpono no nā valve i makemake ʻia. ʻO ka mana hope o ka pipeline ka valve. Hoʻoponopono ka mea wehe kiwi i ke ʻano kahe o ka waena ma ka pipeline. ʻO ke ʻano o ka valve runner e loaʻa i ka valve kekahi mau hiʻohiʻona kahe. Pono e noʻonoʻo ʻia kēia i ke koho ʻana i ka valve kūpono loa no ka hoʻokomo ʻana i ka ʻōnaehana pipeline.
