ʻO ke kumu o ka hoʻohana ʻana i ka valve check ka mea e pale ai i ka hoʻohuli ʻana i ke kahe o ka waena, a ua hoʻokomo pinepine ʻia kahi pahu nānā ma ka puka o ka pamu. Eia kekahi, pono e hoʻokomo ʻia kahi valve check ma ka puka o ka compressor. I ka pōkole, i mea e pale ai i ka hoʻohuli ʻana o ka mea waena, pono e hoʻokomo ʻia kahi valve check ma luna o nā mea hana, mea hana a i ʻole pipeline.
ʻO ka maʻamau, hoʻohana ʻia nā ʻūhā hoʻokiʻekiʻe kiʻekiʻe ma luna o nā pipeline ākea me ke anawaena inoa o 50mm. Hiki ke hoʻokomo ʻia ka valve check lift straight-through ma nā laina paipu ākea a me ke kūpaʻa. Hoʻokomo wale ʻia ka valve lalo ma ka pipeline kūpaʻa o ka inlet pump, a kahe ka waena mai lalo a luna.
Hiki ke hana ʻia ka swing check valve i ke kaomi hana kiʻekiʻe loa, hiki i ka PN ke hiki i ka 42MPa, a hiki ke hana ʻia ka DN i mea nui loa, hiki ke piʻi ka nui ma mua o 2000mm. E like me nā mea likeʻole o ka pūpū a me ke sila, hiki ke hoʻohanaʻia i kēlā me kēiaʻano hana hana a me ke ana wela hana. He wai, mahu, kinoea, corrosive medium, aila, meaʻai, lāʻau lapaʻau, a me nā mea ʻē aʻe. ʻO ka mahana hana o ka waena ma waena o -196 ~ 800 ℃.
ʻAʻole i kaupalena ʻia ke kūlana hoʻonohonoho o ka swing check valve, ua hoʻokomo pinepine ʻia ma ka pipeline horizontal, akā hiki ke kau ʻia ma ka pipeline vertical a i ʻole ka pipeline inclined.
He haʻahaʻa haʻahaʻa a me ke anawaena nui ka manawa kūpono o ka valve check butterfly, a ua kaupalena ʻia ka manawa hoʻokomo. No ka mea, ʻaʻole hiki ke kiʻekiʻe loa ke kaomi hana o ka valve check butterfly, akā hiki ke nui ke anawaena nominal, hiki ke piʻi aku ma mua o 2000mm, akā aia ke kaomi nominal ma lalo o 6.4MPa. Hiki ke hana ʻia ke ʻano wafer, i hoʻokomo pinepine ʻia ma waena o nā flanges ʻelua o ka pipeline ma ke ʻano o ka pilina wafer.
ʻAʻole i kaupalena ʻia ke kūlana hoʻonohonoho o ka butterfly check valve, hiki ke kau ʻia ma ka pipeline horizontal, pipeline vertical a i ʻole pipeline inclined.
He kūpono ia no nā paipu e pili ana i ka hāmare wai. Hiki i ka diaphragm ke hoʻopau maikaʻi i ka hāmare wai ma muli o ke kahe ʻana o ka mea waena. No ka mea ua kaupalena ʻia ka mahana hana a me ke kaomi hana ʻana o nā kīwaha nānā diaphragm e ka mea diaphragm, hoʻohana maʻamau lākou i nā paipu haʻahaʻa haʻahaʻa a me ka wela maʻamau, ʻoi aku hoʻi no nā paipu wai paipu. ʻO ka maʻamau, ʻo ka mahana hana o ka waena ma waena o -20 ~ 120 ℃, a ʻoi aku ka liʻiliʻi o ke kaomi hana ma mua o 1.6MPa, akā hiki i ka diaphragm check valve ke loaʻa i kahi anawaena nui aʻe, a ʻo ka DN kiʻekiʻe hiki ke ʻoi aku ma mua o 2000mm.
Ua hoʻohana nui ʻia ʻo Diaphragm check valve i nā makahiki i hala iho nei ma muli o kāna hana wai maikaʻi loa, ʻano maʻalahi ke ʻano a me ke kumu kūʻai haʻahaʻa.
He maikaʻi ka hana hoʻopaʻa ʻana o ke kinipōpō, ka hana hilinaʻi a me ke kū ʻana o ka hāmare wai maikaʻi no ka mea ʻo ka sila he pōʻai i uhi ʻia me ka lāʻau; a no ka mea hiki i ka sila ke pōpō hoʻokahi a i ʻole nā pōpō lehulehu, hiki ke hana ʻia i ke anawaena nui. Eia nō naʻe, ʻo kona sila he poʻo puʻupuʻu i uhi ʻia me ka rubber, ʻaʻole kūpono ia no nā pipeline kiʻekiʻe, akā kūpono wale no nā pipelines medium a haʻahaʻa.
No ka mea hiki ke hana ʻia nā mea pūpū o ka pahu hoʻopaʻa pōleʻa me ke kila kila, a hiki ke uhi ʻia ke poʻo o ka sila me ka plastik ʻenekini PTFE, hiki ke hoʻohana ʻia i nā pipeline me nā media corrosive maʻamau.
ʻO ka mahana hana o kēia ʻano o ka valve check ma waena o -101 ~ 150 ℃, ʻo ke kaomi nominal ʻo ≤4.0MPa, a ʻo ke anawaena nominal ma waena o 200 ~ 1200mm.
