He aha nā hemahema e pili ana i ka hoʻoheheʻe ʻana o nā valve?

1. ʻO ka stomata

He lua liʻiliʻi kēia i hoʻokumu ʻia e ke kinoea i ʻole e puka aku ke kaʻina hana paʻa metala i loko o ka metala. He laumania kona paia o loko a loaʻa iā ia ke kinoea, nona ka reflectivity kiʻekiʻe i ka nalu ultrasonic, akā no ka mea he poepoe a ellipsoid paha, he kīnā kiko ia, ka mea e hoʻopilikia ai i kona amplitude reflection. Hoʻopalahalaha ʻia ka lua ea i loko o ka ingot i loko o kahi kīnā wahi ma hope o ka forging a i ʻole ka ʻōwili ʻana, he mea maikaʻi ke loaʻa ma ka nānā ʻana o ka ultrasonic.

2. Ka huki ʻana a me ka lua wehe

Ke hoʻomaʻalili ʻia a paʻa ka hoʻolei ʻana a i ʻole ka ingot, pono e emi ka nui, a ʻaʻole hiki ke hoʻohui ʻia ka hemahema hakahaka e ka metala wai. ʻO nā vovities nui a paʻa i kapa ʻia he mau lua shrinkage, a ʻo nā hakahaka liʻiliʻi a hoʻopuehu ʻia ua kapa ʻia he wehe. Ma muli o ke kānāwai o ka hoʻonui wela a me ka ʻūlū anu, ua paʻa ka lua shrinkage, akā aia nā ʻano like ʻole, nā nui a me nā kūlana me nā ʻano hana like ʻole, a lilo ia i kīnā ke hoʻonui ʻia i ke kino hoʻolei a i ʻole ingot. Inā ʻaʻole ʻoki ka ingot i ka lua shrinkage maʻemaʻe a lawe mai i loko o nā ʻāpana forging, e lilo ia i lua shrinkage koena (lua shrinkage koena, paipu shrinkage koena).

3. ʻOkiʻoki i ka ʻōpala

ʻO ka ʻōpala i loko o ke kaʻina hana hoʻoheheʻe a i ʻole ka refractory ma ke kino umu e ʻili i loko o ka metala wai, a huki ʻia i loko o ka ingot hoʻolei a i ʻole ke kila i ka wā e ninini ana, e hana ana i ka hemahema slag clamp. ʻAʻole noho wale ka slag, pinepine i kahi kūlana mānoanoa a i ʻole i hoʻopuehu ʻia ma nā hohonu like ʻole, ua like ia me nā hemahema volume akā pinepine he linearity kekahi.

4. Hui pū ʻia

ʻO nā huahana hopena i ke kaʻina hana hoʻoheheʻe (e like me ka oxide, sulfide, a me nā mea ʻē aʻe) - nā hoʻokomo ʻole metala, a i ʻole ka mea i hoʻohui ʻia o kekahi mau ʻāpana i nā ʻāpana metala ʻaʻole i hoʻoheheʻe loa ʻia a noho mau e hana i nā hoʻokomo metala, e like me ke kiʻekiʻe o ka density, nā ʻāpana hoʻoheheʻe kiʻekiʻe - tungsten, molybdenum, a me nā mea ʻē aʻe.

5. Ka wehewehe ʻana

ʻO ka hoʻokaʻawale ʻana i ka hoʻolei ʻana a i ʻole ka ingot e pili ana i ka hoʻokaʻawale ʻāpana i hoʻokumu ʻia i ka hoʻolaha like ʻole o nā ʻāpana i ke kaʻina hana hoʻoheheʻe a i ʻole ke kaʻina hana hoʻoheheʻe o ka metala. ʻOkoʻa nā waiwai mechanical o ka wahi me ka hoʻokaʻawale ʻana mai nā waiwai mechanical o ka matrix metala holoʻokoʻa, a ʻo ka ʻokoʻa ma mua o ka pae maʻamau i ʻae ʻia e lilo i kīnā.

6. Ke hoʻolei ʻana i nā māwae

ʻO ke kumu nui o ka māwae i loko o ka hoʻolei ʻana, ʻo ia ke koʻikoʻi o ka hoʻomāalili ʻana o ka metala ma mua o ka ikaika hope loa o ka mea, pili ia i ke ʻano o ka hoʻolālā hoʻolei a me ke kaʻina hana hoʻolei ʻana, a pili pū kekahi i ka ʻike o ka haki ʻana o kekahi mau haumia i loko o nā mea metala (e like me ka nui o ka sulfur, ka brittleness anu, ka nui o ka phosphorus, a pēlā aku). I loko o ke koʻokoʻo, e loaʻa nō hoʻi nā māwae i loko o ke aniani koʻokoʻo, a i ka hana ʻana o nā billet ma hope, e noho mau ia i loko o ka hana ʻana ma ke ʻano he māwae kūloko o ka hana ʻana.

Eia kekahi, ʻo Tianjin Tanggu Water Seal Valve Co., Ltd. he ʻenehana holomua i ka noho elastic e kākoʻo ana i nā ʻoihana, ʻo nā huahanakiwikā peʻapeʻa noho laholio, kiwikā pulelehua lug, kiwikā pulelehua concentric flange pālua, flange pāluakiwikā pulelehua ʻano ʻē, kiwikā kaulike,kiwikā hōʻoia papa pālua wafer, Y-Strainer a pēlā aku. Ma Tianjin Tanggu Water Seal Valve Co., Ltd., haʻaheo mākou i ka hāʻawi ʻana i nā huahana papa mua e hoʻokō ana i nā kūlana ʻoihana kiʻekiʻe loa. Me kā mākou ākea o nā valves a me nā mea hoʻopili, hiki iā ʻoe ke hilinaʻi iā mākou e hāʻawi i ka hopena kūpono no kāu ʻōnaehana wai. E kāhea 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.
