Inivalveubunjineli, ixabiso leCv (i-Flow Coefficient) yolawuloivalveibhekiselele kwisantya sokuhamba komthamo okanye isantya sokuhamba kobunzima bombhobho ophakathi ngevalve ngexesha leyunithi kunye naphantsi kweemeko zovavanyo xa umbhobho ugcinwa kuxinzelelo olungagungqiyo. Oko kukuthi, umthamo wokuhamba wevalve.
Ukuphakama kwexabiso lokuhamba kwe-coefficient, iphantsi ilahleko yoxinzelelo njengoko ulwelo luhambaivalve.
Ixabiso le-Cv yevalve kufuneka igqitywe ngokuvavanya nokubala.
ICVixabisoyiparameter yobugcisa ebalulekileyo elinganisa umthamo wokuhamba kwevalve yokulawula phantsi kweemeko ezithile. Ixabiso le-CV alibonisi kuphela ukusebenza kwe-valve ngokwayo, kodwa ihambelana ngqo noyilo kunye nokusebenza kakuhle kwenkqubo yokulawula ulwelo.
Inkcazo idla ngokusekelwe kule miqathango ilandelayo: iivalveivuleke ngokupheleleyo, umahluko woxinzelelo yi-1 lb/in² (okanye 7KPa) eziphelweni, kwaye ulwelo yi-60°F (15.6°C) yamanzi acocekileyo, ngelo xesha umthamo wolwelo (kwiigaloni zase-US) odlula kwivalve ngomzuzu lixabiso le-Cv yevalvu. Kufuneka kuqatshelwe ukuba i-coefficient yokuhamba e-China isoloko ichazwa kwi-metric system, kunye nesimboli se-Kv, kunye nobudlelwane kunye nexabiso le-Cv yi-Cv=1.156Kv.
Indlela yokumisela umgangatho wevalve ngexabiso leCv
1. Bala ixabiso leCV elifunekayo:
Ngokweemfuno ezithile zenkqubo yokulawula ulwelo, njengokuhamba, ukunyanzeliswa koxinzelelo, okuphakathi kunye nezinye iimeko, ixabiso leCv elifunekayo libalwa ngokusebenzisa ifomyula ehambelanayo okanye isofthiwe. Eli nyathelo lithathela ingqalelo izinto ezifana neempawu ezibonakalayo zolwelo (umzekelo, i-viscosity, ubuninzi), iimeko zokusebenza (umzekelo, ubushushu, uxinzelelo), kunye nendawo yevalve.
2. Khetha idiameter yevalvu echanekileyo:
Ngokwexabiso elifunekayo le-Cv elifunekayo kunye nexabiso le-Cv elilinganisiweyo levalve, i-diameter yevalve efanelekileyo ikhethiwe. Ixabiso le-Cv elilinganisiweyo le-valve ekhethiweyo kufuneka lilingane okanye lincinci ngaphezu kwexabiso le-Cv elifunekayo ukuze kuqinisekiswe ukuba i-valve inokuhlangabezana nemfuno yangempela yokuhamba. Ngexesha elifanayo, kuyimfuneko ukuqwalasela ezinye izinto ezifana nezinto eziphathekayo, isakhiwo, ukusebenza kokutywinwa, kunye nemodi yokusebenza yevalve ukuqinisekisa ukuba ukusebenza ngokubanzi kwevalve kuhlangabezana neemfuno zenkqubo.
3. Ukuqinisekiswa kunye noLungiso:
Emva kokhetho lokuqala lweivalvei-caliber, ukuqinisekiswa okuyimfuneko kunye nohlengahlengiso kufuneka lwenziwe. Oku kubandakanya ukuqinisekisa ukuba ukuhamba kwevalve kuhlangabezana neemfuno zenkqubo ngokusebenzisa izibalo zokulinganisa okanye uvavanyo lwehlabathi lokwenene. Ukuba ukuphambuka okukhulu kufunyenwe, kunokufuneka ukubala kwakhona ixabiso le-Cv okanye ulungelelanise i-diameter yevalve.
Isishwankathelo
Kwinkqubo yokubonelela ngamanzi kwisakhiwo, ukuba i-valve yokulawula ayihambisani nexabiso le-CV efunekayo, ipompo yamanzi inokuqalisa kwaye imise rhoqo okanye iqhube kumthwalo ophezulu ngamaxesha onke. Oku akukona nje inkcitho yamandla ombane, kodwa ngenxa yokuguquguquka rhoqo koxinzelelo, kunokukhokelela ekudibaneni kwemibhobho evulekileyo, ukuvuza, kwaye kunokubangela umonakalo kwimpompo ngenxa yokugqithiswa kwexesha elide.
Isishwankathelo, ixabiso leCv yevalve yokulawula liyisalathisi esibalulekileyo sokulinganisa umthamo wayo wokuhamba. Ngokubala ngokuchanekileyo ixabiso le-Cv kunye nokumisela i-valve caliber efanelekileyo esekelwe kuyo, ukuzinza kunye nokusebenza kakuhle kwenkqubo yokulawula umbane kunokuqinisekiswa. Ngoko ke, kwinkqubo yokukhetha i-valve, ukuyila inkqubo kunye nokusebenza kakuhle, ingqalelo epheleleyo kufuneka ihlawulwe ekubaleni kunye nokusetyenziswa kwexabiso leCv.
