He aha ka Cast steel gate valve?
ʻO nā ʻāpana wehe a pani ʻana o ka ʻīpuka Cast steel gate valve, ʻo ia ke ʻano o ka wedge, ʻo ia ke kumu i kapa ʻia ai lākou ma ke ʻano he wedge gate valve.Hiki ke wehe piha ʻia ka ʻīpuka pāpaʻa a paʻa loa a ʻaʻole hiki ke hoʻoponopono ʻia a hoʻopaʻa ʻia. , inā e hoʻohana ʻia ʻo ia me ka hāmama hapa, e nui ka poho o ke kaomi a e pōʻino ka ʻili o ka sila ma lalo o ka hopena o ka wai.
Hoʻolei ʻia ka pahu kila kila, i hoʻolālā ʻia a hana ʻia e like me ka American standard API600, ASME B16.34, flanged end i ASME B 16.5, a hoʻāʻo ʻia e like me API598, loaʻa kahi hana kikoʻī a kaohi ʻia e hoʻokuʻu a pale i ke kahe o nā ʻano wai like ʻole i loko. paipu.
ʻO nā hiʻohiʻona nui o Cast steel gate valve
Nā hiʻohiʻona nui
- ʻOki maʻamau: Loaʻa ka ʻoki API 1(13Cr), ʻoki 5 (Stellite Gr.6 i mua i ka wepa a me ka noho) a me ka ʻoki 8 (Stellite Gr.6 i alo ma ka noho).
- Nui ka nui a hiki i 72", a me ke kaomi hana kiʻekiʻe 2500lbs
- wili hikiwaweme ka hoʻopili haʻahaʻa waena kumu-wedge, i loko o CA15 paʻa (13Cr) a i ʻole i paʻa me 13Cr, SS 316, Monel a i ʻole Stellite Gr.6.Hoʻopili ʻia ka wedge a hoʻopaʻa ʻia i kahi aniani a alakaʻi paʻa ʻia e pale i ka huki ʻana a me ka pōʻino o ka noho.
- Liʻiliʻi kahe kū'ē a me ka puʻe poho, ma muli o ke ala pololei a me ka piha hamama wedge.
- Sila ʻaoʻao ʻelua
- manawa lōʻihi e pani a hoʻolohi i ka neʻe ʻana o ka wedge, ʻaʻohe mea hāmare wai no nā ʻīpuka ʻīpuka.
- ʻO ke ʻano paʻa, ʻano maʻalahi, maʻalahi ia no ka hana ʻana a me ka mālama ʻana, a me ka laulā o ka noi.
- Pono ʻia ka torque liʻiliʻi i ka wā e wehe ai a pani ʻia. no ka wehe ʻana a i ʻole pani ʻia, pili ka neʻe ʻana o ka wedge i ke ala kahe o ka waena.
