ʻOiai ʻo ia ka valve i hoʻohana nui ʻia, ʻo ka valve pōpō kekahi ʻano valve i ʻoi aku ka nui. Hoʻokō nā ʻano like ʻole i ka noi a ka mea hoʻohana i nā manawa waena like ʻole, nā ʻano mahana like ʻole a me nā koi hana like ʻole i ke kaʻina hana maoli. Ma lalo nei e hoʻolauna ʻia nā ʻano o kekahi mau valve pōpō maʻamau e like me nā valve pōpō lana, nā valve pōpō paʻa, nā valve hapalua pōpō eccentric, nā valve pōpō ʻano V a me nā valve pōpō i hoʻopaʻa ʻia me ka fluorine.
Ma muli o ke ʻano a me ka hana, hiki ke māhele ʻia i:
1. Aia kekahi mau ʻano o nā kiwikā poepoe. He aha nā kiwikā poepoe lana: Hoʻohana ʻia nā kiwikā poepoe lana e like me nā sila a lana ka poepoe. Hoʻohana ia i ke kaomi o ka medium e hoʻokuke i ka poepoe e neʻe i ka mamao a ʻomi i ka noho kiwikā elastic e hoʻokō i ka hopena sila. He nui ke kū'ē ʻana o kēia ʻano kiwikā lana a kūpono wale nō ia no nā pipelines a me nā lako me ka caliber o DN "200 a me ke kaomi o PN "100. Inā nui loa ke anawaena o ka poepoe, e kulou ia i ke kino kiwikā a hāʻule ma lalo o ke kaomi o ka medium; inā kiʻekiʻe loa ke kaomi, e ʻomi ʻia ka kiwikā poepoe a elastic a e hoʻololi mau ʻia ka noho kiwikā elastic, hiki ke hōʻino i ka sila a hoʻopilikia i ke ola o ka kiwikā poepoe.
2. Hoʻopaʻa ʻia ka valve pōpō paʻa e ʻelua mau kumu o luna a me lalo. Ua lako ka noho valve me kahi puna lau a i ʻole kahi puna wili cylindrical. Ke hoʻolako ʻia, ua hoʻopaʻa ʻia ka puna o ka noho valve e hana i kahi ikaika paʻa mua e hoʻokō ai i ke sila mua o ka valve. Hoʻokuke ke kaomi i ka valve i ka wā e hoʻohana ai. Neʻe ka noho i ka pōpō e hoʻokō ai i kahi sila. No ka mea, ʻaʻole neʻe ka pōpō, ua kapa ʻia ʻo ia he valve pōpō paʻa. ʻOi aku ka hilinaʻi o kēia ʻano hoʻopaʻa ʻana ma mua o nā valve pōpō lana ma muli o kona hilinaʻi sila. Hiki ke hoʻohana ʻia ma kahi ākea ākea, ʻaʻole wale no nā anawaena liʻiliʻi haʻahaʻa haʻahaʻa, akā no nā anawaena nui kiʻekiʻe. Akā ʻoi aku ka paʻakikī o kona ʻano.
, He kiʻekiʻe ke kumukūʻai, i ke koho ʻana, pono ʻoe e koho e like me nā pono maoli.
3. ʻO ka valve hemispherical eccentric. Hoʻohana kēia ʻano valve pōpō i kahi ʻano eccentric. ʻO ke kumu o ke ʻano like me ke ʻano o ka valve butterfly paʻakikī eccentric multi-layer. ʻAʻohe ʻaʻahu o ka noho valve a me ka pōpō a he hana sila paʻa. ʻO ka pōpō he 1/4 wale nō o ka valve pōpō maʻamau. He ʻili piʻo kona, māmā ke kaumaha a haʻahaʻa ke kumukūʻai. Loaʻa iā ia kahi hopena shearing a hiki ke hoʻohana ʻia i loko o kahi pipeline waena me nā olonā lōʻihi me ka ʻole o ka jamming.
4. ʻOi aku ka nui o ka flange o ka valve ball insulation thermal ma mua o ka valve ball flange maʻamau. Hoʻohana ia i kahi kino valve integral a me kahi hoʻolālā pōpō i kau ʻia ma ka ʻaoʻao. Hoʻopili ʻia kahi ʻaʻahu metala ma waena o nā flanges i hoʻonui ʻia ma waho o ke kino valve. Ua kapa ʻia hoʻi he valve ball jacketed. Hoʻokomo ʻia nā interfaces Jacketed ma nā ʻaoʻao ʻelua o ke kino valve, hiki ke holoi ʻia me ka mahu a i ʻole ke kinoea wela ʻē aʻe e pale aku i ka medium mai ka paʻa ʻana a i ʻole ka crystallization ma ka mahana o ka lumi. Hoʻohana nui ʻia nā valves ball insulation thermal i nā pipelines a me nā mea hana i maʻalahi ke crystallize a koi i ka insulation thermal i ka petroleum, kemika, metallurgical, a me nā ʻōnaehana lāʻau lapaʻau.
5. ʻO ka valve pōpō ʻano-V kahi valve pōpō hoʻoponopono. He ʻokoʻa loa ka puka kahe o ka pōpō mai ka puka pololei o ka valve pōpō maʻamau. He ʻano V ka pōpō a hoʻohana pinepine i kahi ʻano paʻa me ʻelua mau kumu o luna a me lalo.
6. Hoʻohana pinepine ʻia ka valve pōpō i hoʻopaʻa ʻia me ka fluorine i nā pipelines lako medium haʻahaʻa a me ka corrosive ikaika. Hoʻopaʻa ʻia kēia ʻano valve pōpō me nā plastics ʻenekinia pale corrosion e like me PFA a i ʻole FEP ma nā ʻāpana āpau o ke kahawai kahe e pili ana me ka medium. Hiki iā ia ke pani i ke kila kila pipiʻi a me Hastelloy ma lalo o ke kūlana o ka ʻole e ʻoi aku ma mua o ka mahana lawelawe o ka rubber fluorine i loko o ka pipeline haʻahaʻa haʻahaʻa. , Monel alloy, No. 20 alloy, e hoʻoponopono i ka pilikia o ka lawe ʻana i nā media corrosive kiʻekiʻe i nā pipelines petrochemical a me ke kemika

ʻO Nortech kekahi o nā mea hana valve ʻoihana alakaʻi ma Kina me ka palapala hōʻoia maikaʻi ISO9001.
