Hiki ke hoʻololi ʻia ka pahu hoʻopaʻa kaomi hoʻoluhi kaomi DLF08-00

ʻO ka valve puka o ka valve relief e pili ana i ka valve puka e pani (puka) a neʻe pololei ma ka laina waena. Hoʻohana ʻia ka valve puka no ka wehe ʻana i ka pipeline. ʻO ka valve puka he mea hoʻohana nui ʻia. Hoʻohana maʻamau ia no nā mea ʻoki ʻoki me DN≥50 mm.. I kekahi manawa, hoʻohana ʻia nā ʻīpuka puka no nā mea ʻoki liʻiliʻi. Loaʻa nā pōmaikaʻi o nā ʻīpuka puka: ① Keakea wai liʻiliʻi. ② He liʻiliʻi ka ikaika o waho e wehe a pani i ka pahu hoʻomaha. (3) ʻaʻole i kaupalena ʻia ke kuhikuhi o ka mea. (4) i ka wā e wehe piha ʻia ai, ʻoi aku ka liʻiliʻi o ka ʻili o ka sila e nā mea hana ma mua o ka ʻoki ʻoki. ⑤ He maʻalahi loa ke kiʻi a maikaʻi ke kaʻina hana forging. He mau hemahema kekahi o na kiwi puka puka: ① ʻO ke kiʻekiʻe kiʻekiʻe a me ke kēkelē wehe. ʻO ka lumi o loko e pono ai no ka hui ʻana he nui. ② I ka wā o ka wehe ʻana a me ka pani ʻana i ka hana, aia ka piliki pili ma waena o nā wahi hoʻopaʻa paʻa, kahi maʻalahi ke kumu o ka friction. ③ Loaʻa i ʻelua mau ʻāpana hoʻopaʻa ʻana i nā ʻīpuka puka, he paʻakikī ke hana, hana, wili a mālama. Hiki ke hoʻokaʻawale ʻia nā ʻīpuka puka i: ​​(1) nā ʻīpuka paʻa like: ʻo nā ʻili hoʻopaʻa e like me ke axis vertical, ʻo ia hoʻi, ʻo nā ʻaoʻao hoʻopaʻa ʻelua e like me kekahi. I loko o nā ʻīpuka pāpaʻi like, ʻo ke ʻano me ka wedge thrust he mea maʻamau loa ia, ʻo ia hoʻi, aia ʻelua mau wili pahu ma waena o nā ʻīpuka ʻelua. He kūpono kēia ʻīpuka kiwi no nā ʻīpuka puka me ke anawaena liʻiliʻi (DN40-300mm) i ka haʻahaʻa haʻahaʻa. Aia kekahi pā puna ma waena o nā hipa kāne ʻelua, a hiki i ka pūnāwai torsion ke hana i ka ikaika pre-tightening, kahi mea e pono ai i ka hoʻopaʻa ʻana i ka pā kīwaha electromagnetic relief. (2) Wedge gate valve: ʻo ka ili hoʻopaʻa i kahi kihi me ke axis vertical, ʻo ia hoʻi, ʻo nā ʻaoʻao hoʻopaʻa ʻelua e hoʻokumu i kahi kiwi puka wedge. ʻO nā kihi nānā oblique o ka ʻili hoʻopaʻa maʻamau maʻamau 2 52', 3 30', 5, 8, 10, a me nā mea ʻē aʻe. Ma keʻano laulā, ʻoi aku ka kiʻekiʻe o ka mahana, ʻoi aku ka nui o ka ʻike maka e hōʻemi i ka hiki ke hoʻopaʻa ʻia ke hoʻololi ka mahana.
