ʻO ka ʻike maʻamau o nā valves

Ke kumu ʻāpapa
1. ʻO nā palena kumu o ka valve: PN nominal pressure a me DN nominal diameter
2. ʻO ka hana kumu o ka valve: e ʻoki i ka mea i hoʻopili ʻia, hoʻoponopono i ka kahe kahe, a hoʻololi i ke ala kahe
3, ʻo nā ala nui o ka pili valve: flange, thread, welding, wafer
4, ke kaomi o ka valve —— ka pae wela e hōʻike ana: ʻokoʻa nā mea like ʻole, nā mahana hana ʻokoʻa, ʻokoʻa ka palena kiʻekiʻe i ʻae ʻia ʻaʻohe hopena o ka hana.
5. ʻElua mau ʻōnaehana nui o ka flange standard: ʻEulopa mokuʻāina a me ʻAmelika mokuʻāina.
He ʻokoʻa loa ka pili o ka flange pipe o nā ʻōnaehana ʻelua a ʻaʻole hiki ke hoʻohālikelike ʻia;
ʻOi aku ka maikaʻi o ka hoʻokaʻawale ʻana ma ke kiʻekiʻe o ke kaomi:
ʻO ka ʻōnaehana mokuʻāina ʻEulopa ʻo PN0.25,0.6, 1.0, 1.6, 2.5, 4.0, 6.3, 10.0, 16.0, 25.0, 32.0, 40.0MPa;
ʻO ka ʻōnaehana mokuʻāina ʻo US ʻo PN1.0 (CIass75), 2.0 (CIass150), 5.0 (CIass300), 11.0 (CIass600), 15.0 (CIass900), 26.0 (CIass1500), 42.0 (CIass2500) MPa.
ʻO nā ʻano nui o ka flange paipu ʻo: integral (IF), plate flat welding (PL), neck flat welding (SO), neck butt welding (WN), socket welding (SW), screw (Th), butt welding apo loose sleeve (PJ / SE) / (LF / SE), flat welding apo loose sleeve (PJ / RJ) a me flange uhi (BL), etc.
ʻO ka flange sealing surface type ka mea nui: piha mokulele (FF), protrusion surface (RF), concave (FM) convex (M) surface, apo connect surface (RJ), etc.

ʻO nā kiwi maʻamau (maʻamau).
1. Z, J, L, Q, D, G, X, H, A, Y, S i kēlā me kēia o ke ʻano o ka valve type code e hōʻike ana: ʻīpuka ʻīpuka, kīwī hoʻokuʻu, kiwi puʻupuʻu, kiwi pōlele, kiwi lele, kiwipili diaphragm, kiwi hoʻopili, kiwi hoʻopaʻa, kiwi palekana, kiwi hoʻohaʻahaʻa kaomi a me ka pahu wai.
2, Ua ʻōlelo ʻia ka helu helu pili valve 1,2,4,6,7: 1-loko loko, 2-waho, 4-flange, 6-weld, 7-pair clip
3, ʻO ke ʻano o ka hoʻouna ʻana o ke code valve 9,6,3 i ʻōlelo ʻia: 9-electric, 6-pneumatic, 3-turbine worm.
4, ʻO ke kino kīpē mea helu Z, K, Q, T, C, P, R, V i ʻōlelo ʻia: hao hina hina, hao malleable, hao ductile, keleawe a me ka hao, carbon steel, chromium-nickel nickel stainless steel, chromium-nickel-molybdenum stainless steel, chromium-molybdenum vanadium steel.
5, Seal seal or lining code R, T, X, S, N, F, H, Y, J, M, W kēlā me kēia: austenitic stainless steel, copper alloy, rubber, plastic, nylon plastic, fluorine plastic, Cr stainless steel, hard alloy, lining rubber, moner alloy, valve body material.

6. He aha nā kumu nui ʻekolu e noʻonoʻo ʻia i ke koho ʻana i kahi mea hoʻokani?
1) E ʻoi aku ka nui o ka hoʻopuka ʻana o ka mea hana ma mua o ka ukana o ka valve hoʻoponopono a e hoʻohālikelike pono ʻia.
2) No ka nānā ʻana i ka hui maʻamau, ʻo ka ʻokoʻa kaomi ʻae ʻia i kuhikuhi ʻia e ka valve hoʻoponopono e hoʻokō i nā koi kaʻina. Pono e helu ʻia ka ikaika kaulike ʻole o ke kumu valve i ka wā o ka ʻokoʻa nui.
3) Inā hoʻokō ka wikiwiki pane o ka mea hana i nā koi o ke kaʻina hana, ʻoi aku ka nui o ka mea hana uila.
7, hiki i ka hui valve TWS ke hāʻawi i ka valve i?
Puka lele lele noho Rubber: kiwikā wafer butterfly, lug butterfly valve,pāpū lele lele; kiwi puka; hoʻopaʻa pahu;pahu hoʻolikelike, pahu kinipopo, etc.
Ma Tianjin Tanggu Water Seal Valve Co., Ltd., haʻaheo mākou iā mākou iho i ka hāʻawi ʻana i nā huahana papa mua e kū ana i nā kūlana ʻoihana kiʻekiʻe. Me kā mākou ākea ākea o nā valves a me nā pono, hiki iā ʻoe ke hilinaʻi iā mākou e hāʻawi i ka hopena kūpono no kāu ʻōnaehana wai. E kelepona mai iā mākou i kēia lā e aʻo hou e pili ana i kā mākou huahana a pehea e hiki ai iā mākou ke kōkua iā ʻoe.
