ʻO ka Wedge Gate Valve no ka ʻaila En1984 hale hana Kina
He aha ka Gate valve no ka ʻaila?
E like me nā kiwikā puka wedge maʻamau, ʻo nā ʻāpana wehe a pani o ka kiwikā Gate no ka ʻaila he puka, ma ke ʻano o kahi wedge, ʻo ia ke kumu i kapa ʻia ai lākou he kiwikā puka wedge. Hiki ke wehe piha ʻia ka kiwikā puka wedge a pani piha ʻia a ʻaʻole hiki ke hoʻoponopono ʻia a hoʻopaʻa ʻia. Ua hoʻolālā ʻia ka kiwikā puka e hoʻohana ʻia i ka wehe piha ʻana a i ʻole ka pani piha ʻana, no ka mea, ma muli o ke ʻano o kāna mau obturators i loaʻa ke ʻano o kahi wedge, inā e hana ʻia me ka wehe hapa ʻana, e nui ka pohō o ke kaomi a e hōʻino ʻia ka ʻili sila ma lalo o ka hopena o ke wai.ʻO ka hiʻohiʻona nui o ka valve puka wedge DIN-EN ʻo kona ʻili sila ma waena o ka "puka" a me kona noho he pālahalaha, kahi e hopena ai i ka pohō kaomi liʻiliʻi loa.
Kiwikā puka no ka ʻaila
- 2) Kūlike nā Flanges me EN1092-1, a he alo i ka maka EN558-1 a i ʻole ke kūlana Kelemania mua ʻo DIN3202
- 3) Hoʻāʻo ʻia a hoʻāʻo ʻia e like me EN12266, BS6755 a me ISO5208
Nā hiʻohiʻona nui o ka Gate valve no ka ʻaila
Nā Hiʻohiʻona Nui
- ʻO ka wedge palupalu me ka pilina haʻahaʻa o ke kumu-wedge waena, ma CA15 paʻa (13Cr) a i ʻole i hoʻopaʻa ʻia me 13Cr, SS 316, Monel a i ʻole Stellite Gr.6. Ua wili ʻia ka wedge a hoʻopaʻa ʻia i kahi ʻano aniani a alakaʻi paʻa ʻia e pale aku i ka huki ʻana a me ka hōʻino ʻana o ka noho.
- Nā Flanges: EN1092-1, PN10-16-25-40-63-100, a i ʻole nā ana flanges ʻē aʻe i noi ʻia
- Loaʻa nō hoʻi kahi ʻāpana Stellite hardfaced CF8M wedge ma ke noi ʻana.
- ʻO ke kū'ē liʻiliʻi o ke kahe a me ka pohō kaomi, ma muli o ke ala pololei o ke kahe a me ka wedge hāmama piha.
- ʻAno liʻiliʻi, hoʻonohonoho maʻalahi, e maʻalahi ai ka hana ʻana a me ka mālama ʻana, a me ka laulā o ka noi.
- ka manawa lōʻihi e pani ai a lohi i ka neʻe ʻana o ka wedge, ʻaʻohe hanana hāmare wai no nā kiwikā puka wedge.
