Gucomeka-muri hydraulic valve ladrv-10

biranga

Uwitwa Valve ntoya yo kugenzura, nkuko izina ryaryo ribivuga, ni uguhuza valve ufite ubushobozi buto.

Ubushobozi bwurukundo bwa valve nigikoresho cya valve kubushobozi busanzwe. Ubushinwa bugereranywa na C agaciro. Isobanurwa nka: Iyo valve yafunguwe byuzuye, mugihe itandukaniro ryungunike mbere na nyuma ya valve ari 1kg / cm2 hamwe nuburemere buciriritse, misa-) gutemba binyuze muri valve buri saha. Kubintu bidahuye, munsi yimiterere yuzuye (mugihe umubare wa Reynolds uhagije, re> 10 5 kumazi; re> 5.5 × 104 kumuyaga)

Aho:

△ p-igitutu itandukaniro mbere na nyuma ya valve (kg / cm2) ½ ubukana (g / cm3)

Q-Media Flow (M3 / H)

Amerika nibindi bihugu bikoresha agaciro ka C kugirango werekane ubushobozi bwurute. Ku rwego mpuzamahanga, e na c amahame ajyanye n'amashanyarazi akoresha av agaciro kerekana ubushobozi bw'ikirango. Umubano wo guhindura muri bo ni utya:

Cv = 1 .17 c cv = 10 6/4AV c = 10 6/18AV

Ubushobozi bwurutero bwa valve gusa biterwa nimiterere ya valve ubwayo. Mugihe cyo kubara ubushobozi bukenewe bwa valve, byakagombye kumenya ko leta igenda muri valve izaba itandukanye cyane mugihe gisobanura ibitandukanye cyangwa ibiranga ikirundo biratandukanye.

Kubireba igipimo gito cyurugendo, cyane cyane amazi ya virusiki hamwe nigitutu gito, imbogamizi nyamukuru ya fluid ikunze kubura laminari cyangwa imiterere yimitako. Muri laminari, hari isano yumurongo hagati yuburyo bunyura muri valve hamwe nigitandukaniro nigikoresho cyagenwe mbere na nyuma ya valve. Muri leta ivanze yintara zigenda zitemba, hamwe no kongera umubare wa Reynolds, nubwo itandukaniro ryungunike rihoraho, imirire itemba binyuze muri valve iziyongera. Muduruvaye wuzuye, igipimo cyuruzi ntigihinduka numero ya reynolds. Nubwo bimeze bityo, guhitamo guhagarika valve ntoya biracyakorwa nuburyo gakondo na formulaire. Ariko, agaciro kabazwe utandukana cyane nagaciro nyako. Dukurikije amakuru, mugihe CV iri munsi ya CV = 0.01, ikoreshwa gusa nkurutonde rwubushobozi kandi ifite akamaro ka reference. Ubushobozi bwo kuzenguruka bugomba kugenwa nkuko
