Kodi CV imatanthauza chiyani? Kodi mungasankhe bwanji valavu yowongolera pogwiritsa ntchito Cv?

Invalavuuinjiniya, mtengo wa Cv (Flow Coefficient) wa ulamulirovalavulimatanthauza kuchuluka kwa kayendedwe ka madzi kapena kuchuluka kwa madzi omwe amayenda mu chitoliro kudzera mu valavu pa nthawi iliyonse komanso pansi pa mikhalidwe yoyesera pamene chitolirocho chimasungidwa pa mphamvu yosalekeza. Ndiko kuti, mphamvu ya madzi yomwe valavu imayendera.

Mtengo wa flow coefficient ukakwera, kutayika kwa kuthamanga kwa magazi kumachepa pamene madzi akuyenda kudzera muvalavu.

Mtengo wa Cv wa valavu uyenera kudziwika poyesa ndi kuwerengera.

CVmtengondi chizindikiro chofunikira kwambiri chaukadaulo chomwe chimayesa mphamvu ya valavu yowongolera pansi pa mikhalidwe inayake. Mtengo wa CV sumangowonetsa momwe valavuyo imagwirira ntchito, komanso umagwirizana mwachindunji ndi kapangidwe ndi magwiridwe antchito a makina owongolera madzi.

Tanthauzo nthawi zambiri limachokera pazikhalidwe zotsatirazi:valavuIli yotseguka kwathunthu, kusiyana kwa kuthamanga ndi 1 lb/in² (kapena 7KPa) kumapeto, ndipo madzi ndi 60°F (15.6°C) ya madzi oyera, pomwe kuchuluka kwa madzi (mu magaloni aku US) omwe amadutsa mu valavu pamphindi ndi Cv ya valavu. Tiyenera kudziwa kuti flow coefficient ku China nthawi zambiri imafotokozedwa mu metric system, yokhala ndi chizindikiro cha Kv, ndipo ubale ndi Cv value ndi Cv=1.156Kv.

Momwe mungadziwire kuchuluka kwa valavu ndi mtengo wa Cv

1. Werengani mtengo wa CV womwe mukufuna:

Malinga ndi zofunikira zenizeni za dongosolo lowongolera madzi, monga kuyenda, kupanikizika kosiyana, sing'anga ndi zina, Cv yofunikira imawerengedwa pogwiritsa ntchito fomula kapena mapulogalamu ogwirizana. Gawoli limaganizira zinthu monga mawonekedwe enieni a madzi (monga kukhuthala, kuchuluka), momwe amagwirira ntchito (monga kutentha, kupanikizika), ndi malo a valavu.

2. Sankhani valavu yolondola:

Malinga ndi mtengo wa Cv womwe ukufunidwa komanso mtengo wa Cv womwe waikidwa pa valavu, m'mimba mwake woyenera wa valavu umasankhidwa. Mtengo wa Cv womwe waikidwa pa valavu womwe wasankhidwa uyenera kukhala wofanana kapena wokulirapo pang'ono kuposa mtengo wa Cv womwe ukufunidwa kuti valavuyo ikwaniritse kufunikira kwenikweni kwa madzi. Nthawi yomweyo, ndikofunikiranso kuganizira zinthu zina monga zipangizo, kapangidwe kake, magwiridwe antchito otsekera, ndi momwe valavu imagwirira ntchito kuti zitsimikizire kuti magwiridwe antchito onse a valavuyo akukwaniritsa zofunikira za dongosolo.

3. Kutsimikizira ndi Kusintha:

Pambuyo pa kusankha koyamba kwavalavucaliber, kutsimikizira ndi kusintha kofunikira kuyenera kuchitika. Izi zikuphatikizapo kutsimikizira kuti magwiridwe antchito a valavu akukwaniritsa zofunikira za dongosololi kudzera mu kuwerengera koyerekeza kapena kuyesa zenizeni. Ngati papezeka kusiyana kwakukulu, kungakhale kofunikira kuwerengeranso mtengo wa Cv kapena kusintha dayamita ya valavu.

Chidule

Mu dongosolo loperekera madzi la nyumba, ngati valavu yowongolera siikukwaniritsa CV yofunikira, pampu yamadzi imatha kuyamba ndikuyima pafupipafupi kapena kugwira ntchito modzaza kwambiri nthawi zonse. Sikuti izi ndi kungowononga mphamvu zamagetsi zokha, komanso chifukwa cha kusinthasintha kwa kuthamanga kwa mpweya pafupipafupi, zimatha kubweretsa kulumikizidwa kwa mapaipi otayirira, kutuluka madzi, komanso kungayambitse kuwonongeka kwa pampu chifukwa cha kuchuluka kwa madzi kwa nthawi yayitali.

Mwachidule, mtengo wa Cv wa valavu yowongolera ndi chizindikiro chofunikira poyesa mphamvu yake yoyendera. Mwa kuwerengera molondola mtengo wa Cv ndikupeza caliber yoyenera ya valavu kutengera iyo, kukhazikika ndi kugwira ntchito bwino kwa dongosolo lowongolera madzi kumatha kutsimikizika. Chifukwa chake, pakusankha valavu, kapangidwe ka dongosolo ndi kukonza magwiridwe antchito, chisamaliro chonse chiyenera kuperekedwa pakuwerengera ndi kugwiritsa ntchito mtengo wa Cv.

Malingaliro a kampani Tianjin Tanggu Water-Seal Valve Co., Ltdmakamaka kupanga olimba okhala pansivalavu ya gulugufe, valavu ya chipata, Chotsukira cha Y, valavu yolinganiza, valavu yowunikira, valavu yolinganiza, choletsa kuyenda kwa madzi kumbuyo ndi zina zotero.
