I-valve ebizwa ngokuba yivalve yokulawula ukuhamba kwentyatyambo, njengoko igama layo lithetha, yindawo yokulawula enomthamo wokujikeleza kancinci.

Umthamo wokuhamba kwevali ye-valve yisalathiso se-valve phantsi kweemeko ezidityaniswe. I-China imelwe yixabiso le-C. Ichazwa njenge: Xa ivalve evuliwe ngokupheleleyo, xa uxinzelelo lungaphambi nasemva kwevalve yi-1kg / cm2 kunye nobunzima obuphakathi yi-1G Ngolwenzi olungeyomfuneko, phantsi kwemeko yophando opheleleyo (xa inani le-reynolds likhulu ngokwaneleyo, i-5 5 lamanzi; retall; retall)

Phi:

△ Umahluko we-P-uxinzelelo ngaphambi nasemva kwe-valve (kg / cm2) the-υ-ephakathi (G / CM3)

Ukuhamba kwe-q-media (m3 / h)

I-United States kunye namanye amazwe basebenzisa ixabiso le-C ukubonisa ubungakanani bevalve. I-I, I-E kunye neMigangatho ye-C inxulumene nombane osebenzisa ixabiso le-AV ukubonisa ubungakanani bokuhamba kweevila. Ulwalamano lokuguqula phakathi kwabo lulandelayo:

I-CV = 1 .17 C CV = 10 6 / 24av c = 10 6 / 28av

Umthamo wokuhamba kwevelu ixhomekeke kuphela kwi-valve uqobo. Xa kubalwa isikhundla esifunekayo sokuhamba kwe-valve, kufuneka siqatshelwe ukuba imeko yokuhamba kwevalve iya kwahluka kakhulu xa i-Medium yahlukile okanye iimeko zokuhamba ziye zahlukile.

Kwimeko yexabiso elincinci lokuhamba, ngakumbi ulwelo lwe-viscous kunye noxinzelelo oluphantsi, isithintelo esiphambili se-fluid ihlala i-lamid okanye imeko edityanisiweyo ye-laminar kunye nokuhamba kwesiphithiphithi. Ngexesha lokuhamba kwe-laminar, kukho ubudlelwane obuncinci phakathi kokuhamba okuphakathi kwivalve kunye noxinzelelo loxinzelelo ngaphambi nasemva kwevali. Kwimeko edibeneyo yokuhamba kwe-laminar kunye nokuhamba kwesiphithiphithi, ngokunyuka kwenani le-reynolds, nokuba uxinzelelo loxinzelelo luhlala, ubunzima be-dielectric ovuthuzayo buyonyuka. Kwisiphango esipheleleyo, iqondo lokuhamba alitshintshi kwinombolo yeReynolds. Nangona kunjalo, ukukhetha ivalve encinci yokuhamba kweenyawo isaqhutywa ziindlela zemveli kunye nefomula yeBanga. Nangona kunjalo, ixabiso lokubala liphambuka kakhulu kwixabiso elifanelekileyo. Ngokwedatha, xa i-CV ingaphantsi kwe-CV = 0.01, isetyenziswa kuphela njengesalathiso somsebenzi kwaye sibalulekile. Esona sikhundla sijikelezwe sigqityiwe ngokwe
