Inani le-CV litjho ukuthini? Ungayikhetha njani ivalvu yokulawula ngenani le-Cv?

Inivalvuubunjiniyela, inani le-Cv (i-Flow Coefficient) yokulawulaivalvukutjho izinga lokugeleza kwevolumu nofana izinga lokugeleza kwesisindo sephayiphu nge-valve ngesikhathi seyunithi begodu ngaphasi kwemibandela yokuhlolwa lokha iphayiphi nayigcinwa isemfuthweni ongaguqukiko. Okutjho bona, umthamo wokugeleza wevalvu.

Nayiphezulu inani lokugeleza, ukulahlekelwa mfutho kuphansi njengoba uketshezi lugeleza phakathiivalvu.

Inani le-Cv levalvu kufanele linqunywe ngokuhlolwa nokubala.

I-CVukusizayipharamitha eqakathekileko yobuchwepheshe elinganisa amandla wokugeleza kwevalvu yokulawula ngaphasi kweemeko ezithileko. Inani le-CV alitjengisi ukusebenza kwevalvu ngokwayo kwaphela, kodwana lihlobene ngqo nokuklanywa nokusebenza kuhle kwehlelo lokulawula amanzi.

Ihlathululo ivamise ukusekelwe emibandeleni elandelako: iivalvuivulekile ngokupheleleko, umehluko womfutho ngu-1 lb/in2 (nofana 7KPa) emaphethelweni, begodu uketshezi ngu-60°F (15.6°C) wamanzi ahlanzekileko, lapho umthamo we-fluid (ngamalitha we-US) odlula nge-valve ngomzuzu inani le-Cv ye-valve. Kufanele kuqashelwe bona i-flow coefficient e-China ivamise ukuhlathululwa erherhweni le-metric, ngetshwayo elithi Kv, begodu ubudlelwano nenani le-Cv ngu-Cv=1.156Kv.

Indlela yokuthola izinga levalvu ngenani le-Cv

1. Bala inani le-CV elifunwako:

Ngokuya ngeemfuneko ezithileko zesistimu yokulawula uketshezi, njengokugeleza, umfutho ohlukileko, ubujamo obuphakathi nezinye, inani le-Cv elitlhogekako libalwa kusetjenziswa ifomula ehambelanako nofana isofthiwe. Igadango leli lithatha izinto ezifana nobujamo be-fluid (isib., ukuthamba, ukuminyana), ubujamo bokusebenza (isib., amazinga womtjhiso, umfutho), kanye nendawo yevalvu.

2. Khetha ububanzi bevalvu obufaneleko:

Ngokuya ngenani le-Cv elifunwako elibaliweko kanye nenani le-Cv elilinganisiweko levalvu, ububanzi bevalvu obufaneleko bukhethwa. Inani le-Cv elilinganisiweko le-valve ekhethiweko kufanele lilingana nofana libe likhulu kancani kunenani le-Cv elitlhogekako ukuqinisekisa bona i-valve ingahlangabezana nesidingo sokugeleza kwamambala. Ngesikhathi esifanako, kuyatlhogeka bona kuqalwe ezinye izinto ezifana nezinto, isakhiwo, ukusebenza kokuvala, kanye nendlela yokusebenza kwevalvu ukuqinisekisa bona ukusebenza kwevalvu kuhlangabezana neemfuneko zesistimu.

3. Ukuqinisekiswa nokulungiswa:

Ngemva kokukhethwa kokuthoma kweivalvuizinga, ukuqinisekiswa okutlhogekako nokulungiswa kufanele kwenziwe. Lokhu kufaka hlangana ukuqinisekisa bona ukusebenza kwevalvu kuhlangabezana neemfuneko zesistimu ngokusebenzisa ukubalwa kokulingisa nofana ukuhlolwa kwamambala. Nangabe kutholakala ukuphambuka okukhulu, kungaba nesidingo sokubala kabutjha inani le-Cv nofana ukulungisa ububanzi bevalvu.

Isirhunyezo

Ehlelweni lokuphakelwa kwamanzi esakhiweni, nangabe ivalvu yokulawula ayihlangabezani nenani elifunekako le-CV, ipompo yamanzi ingathoma begodu ijame kanengi nofana isebenze ngomthwalo omkhulu ngaso soke isikhathi. Lokhu akusikumosha kwamandla kagesi kwaphela, kodwana ngebanga lokutjhuguluka kwegandeleleko kanengi, kungadosela ekutheni amapayipi angakhululeki, ukuvuza, begodu kungabangela umonakalo epompini ngebanga lokuthwala isikhathi eside.

Ngokufingqa, inani le-Cv levalvu yokulawula liyinkomba eqakathekileko yokulinganisa amandla wayo wokugeleza. Ngokubala ngokunembileko inani le-Cv nokuthola i-valve caliber efaneleko ngokusekelwe kiyo, ukuzinza nokusebenza kuhle kwehlelo lokulawula amanzi kungaqinisekiswa. Ngalokho-ke, emsebenzini wokukhetha ivalvu, ukuklanywa kwehlelo nokwenza ngcono ukusebenza, kufanele kutjhejwe ngokuzeleko ukubalwa nokusetjenziswa kwenani le-Cv.
