E nānā i nā kiwipono e kau ʻia ma luna o nā mea hana, nā mea hana a me nā pipeline i mea e pale ai i ka countercurrent medium.
ʻO ka haʻahaʻa haʻahaʻa haʻahaʻa haʻahaʻa o ka valve check he 0.002-0.004mpa.
E nānā i nā kiwikūpono no ka hoʻomaʻemaʻe ʻana i ka media, ʻaʻole no ka media i loaʻa nā ʻāpana paʻa a me ka viscosity kiʻekiʻe.
ʻO kakapuaʻi wāwaeua hoʻokomo pinepine ʻia ma ka pipeline kūpaʻa o ka inlet pump, a kahe ka waena mai lalo a luna.
ʻOi aku ka maikaʻi o ka hana hoʻopaʻa ʻana ma mua o ke ʻano kowali, a ʻoi aku ka nui o ke kūpaʻa wai.Pono e hoʻokomo ʻia ke ʻano horizontal i ka pipeline ākea, a ʻo ke ʻano kūpaʻa e hoʻokomo ʻia i ka pipeline vertical.
ʻAʻole i kaupalena ʻia ke kūlana hoʻonohonoho o ka swing check valve.Hiki ke hoʻokomo ʻia i loko o nā pipelines horizontal, vertical a inclined pipelines.Inā hoʻokomo ʻia i loko o nā paipu kū pololei, pono ke kahe ʻana o ka waena mai lalo a luna.
ʻO nā pahu hoʻopaʻapaʻa hoʻoluliʻAʻole pono e hana ʻia i loko o nā pahu liʻiliʻi liʻiliʻi, a hiki ke hana i ke kaomi hana kiʻekiʻe.Hiki i ke kaomi nominal ke hiki i ka 42 MPa, a hiki i ke anawaena nominal ke nui, a hiki i 2000 mm.Hiki ke hoʻohana ʻia i kēlā me kēia ʻano hana a me nā pae wela hana e like me ka mea o ka pūpū a me ke sila.ʻO ka wai, ka mahu, ke kinoea, ke kino kino, ka aila, ka lāʻau lapaʻau, a pēlā aku.
He kūpono ka swing check valve no ke kaomi haʻahaʻa a me ka caliber nui, a ua kaupalena ʻia kāna kau ʻana.
ʻAʻole i kaupalena ʻia ke kūlana hoʻonohonoho o ka pahu wafer check valve.Hiki ke hoʻokomo ʻia i loko o ka pipeline horizontal a i ʻole i ka pipeline vertical a inclined.
Nā pahu hoʻopaʻa kinipōpōkūpono no nā paipu haʻahaʻa haʻahaʻa a hiki ke hana ʻia i ka liʻiliʻi nui.
Hiki ke hana ʻia nā mea pūpū o ka pahu hoʻopaʻa pōleʻa me ke kila kila, a hiki ke hoʻopili ʻia ke poʻo o ka sila i loko o nā plastik ʻenehana PTFE.No laila, hiki ke hoʻohana ʻia i nā pipelines o ka media corrosive maʻamau.ʻO ka mahana hana ma waena o - 101 - 150 C, ʻoi aku ka nui o ke kaomi nominal ma mua o 4.0 MPa, a ʻo ka pae koho nominal ma waena o DN200 - DN1200.
E nānā i nā kiwipono e like me ka nui.Pono nā mea hoʻolako valve e hāʻawi i ka ʻikepili i nā nui i koho ʻia e ʻike ai i ka nui o nā kiwi i ka wā e wehe piha ai lākou i kahi kahe kahe i hāʻawi ʻia.
No ke kiʻekiʻe a me ke kaumahanā pahu hopuma lalo o DN50mm,nā kiwi hoʻokiʻekiʻe kiʻekiʻea ma ohoʻokiʻekiʻe kiwi kiwipono e koho.
No ke kaomi haʻahaʻanā pahu hopuma lalo o DN50mm,nā kīwaʻi nānā waferanā kiwi hoʻokiʻekiʻe kiʻekiʻepono e koho.
No ke kiʻekiʻe a me ke kaumahanā pahu hopume DN ʻoi aʻe ma mua o 50 mm a emi ma lalo o 600 mm,swing check valvespono e koho.
No ke kaomi waena a me ka haʻahaʻanā pahu hopume DN ʻoi aku ka nui ma mua o 200 mm a me ka liʻiliʻi ma mua o 1200 mm, ʻaʻahu ʻolekiwi pōlelepono e koho.
No ke kaomi haʻahaʻanā pahu hopume DN ʻoi aʻe ma mua o 50 mm a emi iho ma mua o 2000 mm,nā kīwaʻi nānā waferpono e koho.
No nā paipu e koi ana i ka hāmare liʻiliʻi a i ʻole ka hāmare wai i ka wā e pani ai, pono ke koho ʻia i ka valve nānā kowali lohi.
