Agaciro CV bivuze iki? Nigute ushobora guhitamo valve igenzurwa na Cv agaciro?

Inindangaubwubatsi, agaciro ka Cv (Coefficient Flow) yo kugenzuraindangabivuga umuvuduko wijwi cyangwa umuvuduko mwinshi wumuyoboro unyuze muri valve mugihe cyumwanya no mugihe cyibizamini mugihe umuyoboro ubitswe kumuvuduko uhoraho. Nukuvuga, ubushobozi bwo gutembera bwa valve.

Iyo hejuru ya coefficient yagabanutse, niko igabanuka ryumuvuduko nkuko amazi atembera muriindanga.

Cv agaciro ka valve igomba kugenwa mugupima no kubara.

CVagacironi ikintu cyingenzi cya tekiniki gipima ubushobozi bwo gutembera kwa valve igenzura mubihe byihariye. Agaciro CV ntigaragaza gusa imikorere ya valve ubwayo, ariko kandi ifitanye isano itaziguye nigishushanyo mbonera nuburyo bukoreshwa bwa sisitemu yo kugenzura amazi.

Ubusanzwe ubusobanuro bushingiye kubintu bisanzwe bikurikira :.indangairakinguye rwose, itandukaniro ryumuvuduko ni 1 lb / in² (cyangwa 7KPa) kumpera, naho amazi ni 60 ° F (15,6 ° C) yamazi meza, icyo gihe ubwinshi bwamazi (muri gallon yo muri Amerika) anyura muri valve kumunota nigiciro cya Cv. Twabibutsa ko coefficient de coiffure mubushinwa ikunze gusobanurwa muri sisitemu ya metero, hamwe nikimenyetso Kv, kandi isano nigiciro cya Cv ni Cv = 1.156Kv.

Nigute ushobora kumenya kalibiri ya valve nagaciro ka Cv

1. Kubara agaciro CV yifuza:

Ukurikije ibisabwa byihariye bya sisitemu yo kugenzura amazi, nkurugendo, umuvuduko utandukanye, urwego rwo hagati nibindi bihe, agaciro ka Cv gasabwa kibarwa ukoresheje formulaire cyangwa software ihuye. Iyi ntambwe izirikana ibintu nkibintu bifatika byamazi (urugero, ubukonje, ubucucike), imiterere yimikorere (urugero, ubushyuhe, umuvuduko), hamwe na valve.

2. Hitamo diameter iburyo ya valve:

Ukurikije ibarwa ryifuzwa rya Cv nigiciro cya Cv cyapimwe cya valve, diameter ikwiye yatoranijwe. Igipimo Cv cyapimwe cya valve yatoranijwe igomba kuba ingana cyangwa irenze gato agaciro gasabwa Cv kugirango tumenye neza ko valve ishobora kuzuza ibyifuzo byukuri. Muri icyo gihe, birakenewe kandi gutekereza ku bindi bintu nkibikoresho, imiterere, imikorere ya kashe, nuburyo bwo gukora bwa valve kugirango tumenye neza ko imikorere rusange ya valve yujuje ibisabwa na sisitemu.

3. Kugenzura no Guhindura:

Nyuma yo gutoranya kwambere kwaindangakalibiri, kugenzura no guhindura ibikenewe bigomba gukorwa. Ibi birimo kugenzura niba imikorere ya valve ikora yujuje ibyangombwa bya sisitemu binyuze mu kubara kwigana cyangwa kwipimisha kwisi. Niba gutandukana kwinshi kuboneka, birashobora kuba ngombwa kongera kubara agaciro ka Cv cyangwa guhindura diameter ya valve.

Incamake

Muri sisitemu yo gutanga amazi yinyubako, niba valve igenzura itujuje agaciro ka CV isabwa, pompe yamazi irashobora gutangira no guhagarara kenshi cyangwa ikorera mumitwaro myinshi igihe cyose. Ntabwo ari uguta ingufu z'amashanyarazi gusa, ahubwo kubera guhindagurika k'umuvuduko ukabije, birashobora gutuma imiyoboro ihuza imiyoboro idatemba, igatemba, ndetse ishobora no kwangiza pompe kubera kurenza igihe kirekire.

Muncamake, Cv agaciro kokugenzura valve nikimenyetso cyingenzi cyo gupima ubushobozi bwayo. Muguharura neza agaciro ka Cv no kumenya kalibiri ikwiye ishingiye kuri yo, umutekano hamwe nuburyo bwiza bwa sisitemu yo kugenzura amazi. Kubwibyo, murwego rwo guhitamo valve, sisitemu yogushushanya no gukora neza, hagomba kwitonderwa byuzuye kubara no gushyira mubikorwa agaciro ka Cv.
