ʻO ke kumu o ka hoʻohana ʻana i kahi valve nānā, ʻo ia ke pale aku i ke kahe hope o ka medium, a ua hoʻokomo pinepine ʻia kahi valve nānā ma ka puka o ka pamu. Eia kekahi, pono e hoʻokomo ʻia kahi valve nānā ma ka puka o ka compressor. I ka pōkole, i mea e pale aku ai i ke kahe hope o ka medium, pono e hoʻokomo ʻia kahi valve nānā ma nā lako, hāmeʻa a i ʻole ka pipeline.
Ma keʻano laulā, hoʻohana ʻia nā kiwikā hōʻoia hāpai kū pololei ma nā paipu ʻaoʻao me ke anawaena inoa o 50mm. Hiki ke hoʻokomo ʻia ka kiwikā hōʻoia hāpai pololei ma nā paipu ʻaoʻao a me ke kū pololei. Hoʻokomo wale ʻia ka kiwikā lalo ma ka paipu kū pololei o ke komo ʻana o ka pamu, a kahe ka waena mai lalo a luna.
Hiki ke hana ʻia ka valve hōʻoia Swing i ke kaomi hana kiʻekiʻe loa, hiki i ka PN ke hiki i ka 42MPa, a hiki ke hana ʻia ʻo DN i mea nui loa, hiki ke piʻi i ka nui ma mua o 2000mm. Wahi a nā mea like ʻole o ka pūpū a me ke sila, hiki ke hoʻopili ʻia i kekahi mea hana a me kekahi pae mahana hana. ʻO ka mea hana he wai, mahu, kinoea, mea ʻino, aila, meaʻai, lāʻau lapaʻau, a pēlā aku. ʻO ka mahana hana o ka mea hana ma waena o -196 ~ 800 ℃.
ʻAʻole i kaupalena ʻia ke kūlana hoʻonohonoho o ka valve nānā swing, ua kau pinepine ʻia ma ka pipeline ākea, akā hiki ke kau ʻia ma ka pipeline kū pololei a i ʻole ka pipeline inclined.
ʻO ke kumu kūpono o ka valve nānā pepeke he haʻahaʻa ke kaomi a me ke anawaena nui, a ua kaupalena ʻia ka manawa hoʻonohonoho. No ka mea, ʻaʻole hiki ke kiʻekiʻe loa ke kaomi hana o ka valve nānā pepeke, akā hiki ke nui loa ke anawaena inoa, hiki ke piʻi i mua o 2000mm, akā ʻaʻole ma lalo o 6.4MPa ke kaomi inoa. Hiki ke hana ʻia ka valve nānā pepeke i ʻano wafer, kahi 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 valve nānā pulelehua, hiki ke hoʻokomo ʻia ma ka pipeline ʻākea, ka pipeline kū a i ʻole ka pipeline hilig.
He kūpono ka valve nānā diaphragm no nā paipu e pili ana i ka hāmare wai. Hiki i ka diaphragm ke hoʻopau maikaʻi i ka hāmare wai i hoʻokumu ʻia e ke kahe hope o ka medium. ʻOiai ua kaupalena ʻia ka mahana hana a me ke kaomi hana o nā valve nānā diaphragm e ka mea diaphragm, hoʻohana nui ʻia lākou i nā pipelines haʻahaʻa a me ka mahana maʻamau, ʻoi aku hoʻi no nā pipelines wai piula. Ma ke ʻano laulā, ʻo ka mahana hana o ka medium ma waena o -20 ~ 120 ℃, a ʻoi aku ka liʻiliʻi o ke kaomi hana ma mua o 1.6MPa, akā hiki i ka valve nānā diaphragm ke hoʻokō i kahi anawaena nui aʻe, a ʻo ka DN kiʻekiʻe loa hiki ke ʻoi aku ma mua o 2000mm.
Ua hoʻohana nui ʻia ka valve nānā diaphragm i nā makahiki i hala iho nei ma muli o kāna hana wai ʻole maikaʻi loa, ka hoʻolālā maʻalahi a me ke kumukūʻai hana haʻahaʻa.
Loaʻa i ka valve nānā pōpō ka hana sila maikaʻi, ka hana hilinaʻi a me ke kūpaʻa maikaʻi o ka hāmare wai no ka mea he poepoe i uhi ʻia me ka laholio ka sila; a no ka mea hiki i ka sila ke lilo i pōpō hoʻokahi a i ʻole nā pōpō he nui, hiki ke hana ʻia i loko o kahi anawaena nui. Eia nō naʻe, ʻo kona sila he poepoe hakahaka i uhi ʻia me ka laholio, ʻaʻole kūpono no nā paipu kaomi kiʻekiʻe, akā kūpono wale nō no nā paipu kaomi waena a me ke kaomi haʻahaʻa.
ʻOiai hiki ke hana ʻia ka mea pūpū o ka valve nānā pōpō i ke kila kila, a hiki ke uhi ʻia ka poepoe hakahaka o ke sila me ka plastik ʻenekinia PTFE, hiki ke hoʻohana ʻia i nā pipelines me nā mea ʻino maʻamau.
ʻO ka mahana hana o kēia ʻano valve hōʻoia ma waena o -101 ~ 150 ℃, ʻo ke kaomi maʻamau he ≤4.0MPa, a ʻo ka laulā o ke anawaena maʻamau ma waena o 200 ~ 1200mm.
