Wedge Gate Valve no ka hale hana ʻaila En1984 Kina
He aha ke kīpē puka no ka ʻaila?
e like me nā ʻīpuka ʻīpuka maʻamau, ʻo ka wehe ʻana a me ka pani ʻana o ka ʻāpana ʻīpuka no ka ʻaila ʻo ia ka puka, ma ke ʻano o ka wedge, ʻo ia ke kumu i kapa ʻia ai lākou he kīpē puka wedge.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.ʻO ka hiʻohiʻona nui o ka DIN-EN wedge gate valve, ʻo ia ka mea e hoʻopaʻa ʻia ai ma waena o ka "puka" a me kona noho he palahalaha, kahi e hopena ai i ka poho liʻiliʻi loa.
Puka puka no ka aila
- 2) Kūlike nā flanges me EN1092-1, a he alo a he alo i ka EN558-1 a i ʻole ma mua o Kelemānia DIN3202
- 3) Hoʻāʻo ʻia a nānā ʻia e like me EN12266, BS6755 a me ISO5208
ʻO nā hiʻohiʻona nui o ka puka kīpē no ka ʻaila
Nā hiʻohiʻona nui
- ʻO ka wili hikiwawe me ka hoʻopili haʻahaʻa i waena o ka ʻāʻī, ma ka CA15 paʻa (13Cr) a i ʻole ka ʻaoʻao 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.
- Nā Flanges: EN1092-1, PN10-16-25-40-63-100, a i ʻole nā ʻāpana flanges ʻē aʻe i noi ʻia
- Loaʻa nō hoʻi kahi wedge CF8M paʻakikī Stellite ma ke noi.
- Liʻiliʻi kahe kū'ē a me ka puʻe poho, ma muli o ke ala pololei a me ka piha hamama wedge.
- ʻO ke ʻano paʻa, ʻano maʻalahi, maʻalahi ia no ka hana ʻana a me ka mālama ʻana, a me ka laulā o ka noi.
- manawa lōʻihi e pani a hoʻolohi i ka neʻe ʻana o ka wedge, ʻaʻohe mea hāmare wai no nā ʻīpuka ʻīpuka.
