ʻO ke kumu o ka hoʻohana ʻana i kahi valve nānā, ʻo ia ke pale ʻana i ke kahe hope o ka wai. Ma ke ʻano laulā, pono e hoʻokomo ʻia kahi valve nānā ma ka puka o ka pamu. Eia kekahi,pono e hoʻokomo ʻia kahi valve nānā ma ka puka o ka compressorI ka pōkole, i mea e pale ai i ke kahe hope o ka medium, pono e hoʻokomo ʻia kahi valve nānā ma nā lako, hāmeʻa a i ʻole pipeline. Ma ke ʻano laulā, hoʻohana ʻia kahi valve nānā hāpai kū pololei ma kahi pipeline ākea me ke anawaena inoa o 50mm. Hiki ke hoʻokomo ʻia nā valve nānā hāpai pololei ma nā pipelines ākea a me ke kū. Hoʻokomo wale ʻia ka valve lalo ma ka pipeline kū pololei ma ke komo ʻana o ka pamu, a kahe ka medium mai lalo a luna. Hiki ke hana ʻia ka valve nānā swing i kahi kaomi hana kiʻekiʻe loa, hiki i ka PN ke hiki i 42MPa, a hiki i ka DN ke nui loa, a hiki i ka 2000mm a ʻoi aku paha. Ma muli o ka mea o ka pūpū a me ke sila, hiki ke hoʻohana ʻia no kekahi medium hana a me kekahi pae mahana hana. ʻO ka medium he wai, mahu, kinoea, medium corrosive, aila, meaʻai, lāʻau lapaʻau, a pēlā aku. ʻO ka pae mahana hana waena ma waena o -196 ~ 800 ℃. ʻAʻole i kaupalena ʻia ke kūlana hoʻonohonoho o ka valve nānā swing. Hoʻokomo pinepine ʻia ma ka pipeline ākea, akā hiki ke hoʻokomo ʻia ma ka pipeline kū pololei a i ʻole ka pipeline inclined.

Nā manawa kūpono o kakiwikā nānā pulelehuahe haʻahaʻa ke kaomi a me ke anawaena nui, a ua kaupalena ʻia nā 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 ma mua o 2000mm, akā ʻo ke kaomi inoa ma lalo o 6.4MPa. Hiki ke hana ʻia ka valve nānā pepeke i ʻano clamp, kahi i hoʻokomo pinepine ʻia ma waena o nā flanges ʻelua o ka pipeline, me ka hoʻohana ʻana i ke ʻano pili clamp. ʻAʻole i kaupalena ʻia ke kūlana hoʻonohonoho o ka valve nānā pepeke. Hiki ke hoʻokomo ʻia ma ka pipeline ākea, a i ʻole ma ka pipeline kū pololei a i ʻole ka pipeline inclined.
He kūpono ka valve nānā diaphragm no nā pipelines i maʻalahi 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. Ma muli o ka palena o ka mahana hana a me ke kaomi hoʻohana o ka valve nānā diaphragm e ka mea diaphragm, hoʻohana nui ʻia ia i nā pipelines haʻahaʻa a me ka mahana maʻamau, kūpono loa no nā pipelines wai piula. ʻO ka mahana hana maʻamau ma waena o -20 ~ 120 ℃, a ʻo ke kaomi hana he <1.6MPa, akā hiki ke hana ʻia ka valve nānā diaphragm i ke anawaena nui aʻe, a hiki i ka DN kiʻekiʻe ke hiki aku ma mua o 2000mm. Loaʻa i nā valve nānā diaphragm ke kūpaʻa maikaʻi loa i ka hāmare wai, ka hoʻonohonoho maʻalahi a me ke kumukūʻai hana haʻahaʻa, no laila ua hoʻohana nui ʻia lākou i nā makahiki i hala iho nei.
Mai ka hōʻailona o kaʻO ka valve nānā pōpō he poepoe i uhi ʻia me ka laholio, he hana sila maikaʻi kona, hana hilinaʻi a me ke kūpaʻa maikaʻi i ka hāmare wai; a no ka mea hiki i ka sila ke lilo i hoʻokahi pōpō 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 no nā paipu kaomi waena a me ke haʻahaʻa wale nō. ʻOiai hiki ke hana ʻia ka mea pūpū o ka valve nānā pōpō i ke kila kila, a hiki ke uhi ʻia ka sphere hakahaka o ka sila me nā plastics ʻenekinia polytetrafluoroethylene, hiki ke hoʻohana ʻia i nā pipelines me nā media corrosive maʻamau. ʻO ka mahana hana o kēia ʻano valve nānā ma waena o -101 ~ 150 ℃, ʻo ke kaomi inoa ʻo ≤4.0MPa, a ʻo ka laulā anawaena inoa ma waena o 200 ~ 1200mm.
