Ua kapa ʻia hoʻi ka valve ʻoki ʻia ʻo ka valve cut-off.ʻO ia ka valve i hoʻohana nui ʻia.ʻO ke kumu i kaulana ai ʻo ia ka liʻiliʻi o ka friction ma waena o nā wahi hoʻopaʻa i ka wā o ka wehe ʻana a me ka pani ʻana i ke kaʻina hana, he ʻano lōʻihi, ʻaʻole nui ke kiʻekiʻe o ka wehe, maʻalahi ka hana, a maʻalahi ka mālama., ʻAʻole kūpono wale no ka haʻahaʻa haʻahaʻa a me ke kiʻekiʻe.
ʻO ke kumu hoʻopau o ka valve honua ʻo ia ka hilinaʻi ʻana i ke kaomi o ke kumu valve e hoʻopili pono ai ka ʻili hoʻopaʻa o ka disc a me ka ʻili hoʻopaʻa ʻana o ka noho valve e pale aku i ke kahe ʻana o ke kahe.
ʻO ka pahu pani pani wale nō ka mea e hiki ai ke kahe i ke ala hoʻokahi a ke kuhikuhi ʻia ke kau ʻia.ʻOi aku ka lōʻihi o ka lōʻihi o ka valve pani ʻia ma mua o ka valve puka, a ʻoi aku ka nui o ke kūpaʻa wai, a ʻaʻole ikaika ka hilinaʻi sealing i ka wā lōʻihi.
ʻEkolu ʻano o nā kiwi poʻo honua: nā kiwi poʻo poʻo poʻo pololei, nā kiwi poʻo poʻo poʻo ʻākau a me nā kiwi honua oblique pololei.
ʻO ka pōmaikaʻi ʻoi aku ka maikaʻi ʻo ia i ka wā o ka wehe ʻana a me ka pani ʻana, ʻoi aku ka liʻiliʻi o ka friction ma waena o ka disc a me ka ʻili hoʻopaʻa ʻana o ke kino valve ma mua o ko ka valve puka, no laila ua paʻa ke aahu.ʻO ke kiʻekiʻe o ka wehe ʻana he 1/4 wale nō o ke anawaena o ke ala noho valve, no laila ʻoi aku ka liʻiliʻi ma mua o ka valve puka.ʻO ka maʻamau, hoʻokahi wale nō ili hoʻopaʻa ma ke kino valve a me ka flap valve, no laila ua maikaʻi a maʻalahi ke kaʻina hana.
Nominal pressure or pressure level of stop valve: PN1.0-16.0MPa, ANSI CLASS150-900, JIS 10-20K, nominal diameter a caliber: DN10 ~ 500, NPS 1/2 ~ 36″, hooki i ke ala pili valve: flange , ʻO ka hoʻoheheʻe ʻana i ka butt, ke kaula, a me nā mea ʻē aʻe, pili i ka wela: -196 ℃ ~ 700 ℃, hoʻopau i ke ʻano hoʻokele valve: manual, bevel gear drive, pneumatic, electric, hydraulic, gas-liquid linkage, electro-hydraulic linkage, valve body material: WCB , ZG1Cr18Ni9Ti , ZG1Cr18Ni12Mo2Ti, CF8 (304), CF3 (304L), CF8M (316), CF3M (316L), Ti.Hoʻohana ʻia nā mea like ʻole no ka valve stop, hiki ke hoʻohana ʻia no ka wai, ka mahu, ka aila, ka waikawa nitric, ka waikawa acetic, a me ka media oxidizing., Urea a me nā mea hoʻolaha ʻē aʻe.
ʻO Nortech kekahi o nā mea hana valve ʻoihana nui ma Kina me ka palapala hōʻoia ISO9001.
