Loaʻa i ka valve puka nā hiʻohiʻona o ke kūpaʻa wai liʻiliʻi, ke kaomi pili, ka pae wela, a me nā mea ʻē aʻe, ʻo ia kekahi o ka valve cut-off i hoʻohana pinepine ʻia, i hoʻohana ʻia e ʻoki a hoʻopili i ka waena i ka pipeline.Hiki i ke anawaena shrinkage ke ho'ēmi i ka nui o nā'āpana, e ho'ēmi i ka ikaika e pono ai no ka weheʻana a me ka paniʻana, a hoʻonui i ka laulā noi o nā'āpana.Eia naʻe, piʻi ka poho o ka wai ma hope o ka emi ʻana o ke anawaena.ʻO ka pahu puka puka haʻahaʻa haʻahaʻa ma Kina i hana ʻia me ka hao hao, he mau pilikia koʻikoʻi e like me ka hāʻule ʻana o ke kino a me ka hāʻule ʻana o ka pā pā.ʻO ke kumu kila kalapona o ka pahu puka hao hoʻoheheʻe ʻia he maʻalahi ke ʻōpala, ʻaʻole maikaʻi ka maikaʻi o ka pahu pahu pahu, a ʻoi aku ka nui o ka leaka o loko a me waho.PN10 haʻahaʻa puʻupuʻu kalapona kila puka pāpaʻi i hana ʻia e Shanghai Hugong Valve Factory e pani ana i ka ʻīpuka hao maʻamau, e hoʻoponopono pono i nā pilikia e like me ka maʻalahi o ka pahu o ka puka hao hao e maʻalahi a paʻa, maʻalahi ka hāʻule ʻana o ka pā pā, He maʻalahi ka ʻōpala valve, a ʻaʻole hilinaʻi ka hana sila.

1, ke kaumaha māmā: ua hana ʻia ke kino me ka hao ʻeleʻele ʻeleʻele kiʻekiʻe, ʻo ke kaumaha ma kahi o 20% ~ 30% ka liʻiliʻi ma mua o ke kaumaha o ka ʻīpuka maʻamau, maʻalahi ka hoʻonohonoho ʻana a me ka mālama ʻana.

2. Hoʻopili holoʻokoʻa: hoʻohana ka ʻīpuka i ka pāpaʻi kiʻekiʻe no ka pahu holoʻokoʻa o loko a me waho.ʻO ka ʻenehana vulcanization ʻenehana papa mua o ʻEulopa e hōʻoia i ka nui geometric pololei o ka puka vulcanized, a ʻo ka hipa a me ka ductile hoʻolei ʻana i hilinaʻi, ʻaʻole maʻalahi e hāʻule a loaʻa ka hoʻomanaʻo elastic maikaʻi.

3, ʻano pāpaʻi pāpaʻi poloka: holoi pinepine ka puka kahiko i ka paipu i ka wai ma hope o nā mea o waho e like me ka pōhaku, ka lāʻau, ka sima, ka hao hao, nā ʻano sedimentation ma lalo o ka valve e like me nā puka, maʻalahi ke kumu ʻaʻole hiki ke pani paʻa. a hana lohi, ma ka lalo o ka sila o ka elastic base noho puka kiwikā me ka wai paipu me ka palahalaha manao, 'aʻole maʻalahi ke kumu debris deposition, hana i ka holo unimpeded.

4, hoʻolei kālā hoʻolele kino: ʻae ke kino valve i ka hoʻolei pololei ʻana, ʻo ka nui geometric kūpono e hana ai i ke kino valve me ka ʻole o ka pau ʻana e hiki ke hōʻoia i ka sila ʻana o ka valve.
