Agaciro ka CV bivuze iki? Ni gute wahitamo valve igenzura ukurikije agaciro ka Cv?

Invalveubwubatsi, agaciro ka Cv (Flow Coefficient) k'ubugenzuzivalveyerekeza ku gipimo cy'amazi atemba cyangwa umuvuduko w'amazi menshi anyura muri vali kuri buri gice cy'umuyoboro kandi mu gihe cy'igeragezwa iyo umuyoboro uguma ku gitutu kidahinduka. Ni ukuvuga ubushobozi bw'amazi atemba bwa vali.

Uko igipimo cy'umuvuduko w'amazi kirushaho kuba kinini, niko igihombo cy'umuvuduko kigabanuka uko amazi atembera muvalve.

Agaciro ka Cv k'imvange kagomba kugenwa hakoreshejwe isuzuma n'ibarura.

CV (CV)agacironi igipimo cy'ingenzi cya tekiniki gipima ubushobozi bwo gutembera kwa valve igenzura mu bihe runaka. Agaciro ka CV ntikagaragaza gusa imikorere ya valve ubwayo, ahubwo gafitanye isano itaziguye n'imiterere n'imikorere myiza ya sisitemu igenzura amazi.

Ubusanzwe ibisobanuro bishingiye ku bintu bisanzwe bikurikira:valveifunguye neza, itandukaniro ry'umuvuduko ni 1 lb/in² (cyangwa 7KPa) ku mpera, kandi amazi ni 60°F (15.6°C) y'amazi meza, aho ingano y'amazi (muri galoni za Amerika) anyura muri valve ku munota ari yo gaciro ka Cv ka valve. Tugomba kumenya ko coefficient y'amazi mu Bushinwa ikunze kugaragazwa muri sisitemu ya metric, hamwe n'ikimenyetso cya Kv, kandi isano n'agaciro ka Cv ni Cv = 1.156Kv.

Uburyo bwo kumenya ingano ya valve ukurikije agaciro ka Cv

1. Kubara agaciro ka CV wifuza:

Dukurikije ibisabwa byihariye bya sisitemu yo kugenzura amazi, nko gutembera, umuvuduko utandukanye, ubushyuhe buciriritse n'ibindi, agaciro ka Cv gakenewe kabarwa hakoreshejwe formula cyangwa porogaramu bihuye. Iyi ntambwe ireba ibintu nk'imiterere y'amazi (urugero: ubushyuhe, ubucucike), imiterere y'imikorere (urugero: ubushyuhe, umuvuduko), n'aho valve iri.

2. Hitamo umurambararo wa valve ukwiye:

Dukurikije agaciro ka Cv kabazwe n'agaciro ka Cv ka valve, umurambararo wa valve ukwiye uratoranywa. Agaciro ka Cv ka valve yatoranijwe kagomba kuba kangana cyangwa karenze gato agaciro ka Cv gakenewe kugira ngo valve ishobore guhaza ibyifuzo nyabyo by'umuvuduko. Muri icyo gihe, ni ngombwa kandi gusuzuma ibindi bintu nk'ibikoresho, imiterere, imikorere yo gufunga, n'uburyo valve ikora kugira ngo harebwe ko imikorere rusange ya valve ihuye n'ibisabwa muri sisitemu.

3. Igenzura n'Ivugurura:

Nyuma yo guhitamo bwa mberevalvecaliber, igenzura n'ivugurura bikenewe bigomba gukorwa. Ibi birimo kugenzura ko imikorere y'umuyoboro w'amashanyarazi ihuye n'ibisabwa na sisitemu binyuze mu kubara simulation cyangwa isuzuma ry'ibintu nyabyo. Iyo habonetse itandukaniro rinini, bishobora kuba ngombwa kongera kubara agaciro ka Cv cyangwa guhindura umurambararo wa valve.

Incamake

Mu buryo bwo gutanga amazi mu nyubako, iyo valve igenzura itujuje agaciro ka CV gasabwa, pompe y'amazi ishobora gutangira no guhagarara kenshi cyangwa igakoresha umutwaro mwinshi igihe cyose. Ibi si ugupfusha ubusa ingufu z'amashanyarazi gusa, ahubwo biterwa no guhinduka k'umuvuduko kenshi, bishobora gutuma imiyoboro y'amazi itakaza umurongo, amazi ava, ndetse bishobora no kwangiza pompe bitewe n'umuvuduko mwinshi w'igihe kirekire.

Muri make, agaciro ka Cv ka valve igenzura ni ikimenyetso cy'ingenzi cyo gupima ubushobozi bwayo bwo gutembera. Mu kubara neza agaciro ka Cv no kumenya neza urwego rwa valve ikwiye ishingiyeho, uburyo bwo kugenzura amazi bushobora guhagarara neza kandi bugatanga umusaruro. Kubwibyo, mu gihe cyo guhitamo valve, imiterere ya system no kunoza imikorere, hakwiye kwitabwaho cyane kubara no gukoresha agaciro ka Cv.

Tianjin Tanggu Amazi-Ikidodo Valve Co, ltdahanini bitanga ubushobozi bwo kwicara nezavalve y'ikinyugunyugu, valve y'irembo, Umusuguro wa Y, valve yo kuringaniza, valve yo kugenzura, valve yo kuringaniza, irinda amazi gusohoka inyuma n'ibindi.
