Flow rate thiab velocityvalveFeem ntau yog nyob ntawm txoj kab uas hla ntawm lub valve, thiab tseem muaj feem xyuam rau qhov tsis kam ntawm cov qauv ntawm lub valve mus rau qhov nruab nrab, thiab tib lub sijhawm muaj qee qhov kev sib raug zoo nrog lub siab, qhov kub thiab txias ntawm qhov nruab nrab ntawm lub valve.

Qhov chaw ntws channel ntawm lub valve yog ncaj qha ntsig txog tus nqi ntws thiab tus nqi ntws, thiab tus nqi ntws thiab tus nqi ntws yog ob qhov sib cuam tshuam. Thaum tus nqi ntws tsis tu ncua, qhov khiav ceev yog qhov loj, thiab qhov chaw ntws channel tuaj yeem me dua; Yog tias qhov khiav ceev me me, qhov chaw khiav yuav loj dua. Ntawm qhov tsis sib xws, qhov chaw ntws channel yog qhov loj, thiab nws qhov nrawm nrawm me me; Qhov chaw ntws channel yog me me, thiab nws qhov ntws nrawm yog loj. Tus nqi ntws ntawm qhov nruab nrab yog qhov loj, thiab lub valve txoj kab uas hla tuaj yeem me dua, tab sis qhov kev tiv thaiv tsis zoo yog qhov loj, thiab lub valve yog yooj yim rau kev puas tsuaj. Tus nqi ntws yog qhov loj, uas yuav tsim cov nyhuv electrostatic ntawm cov khoom siv hluav taws xob thiab cov khoom tawg, ua rau muaj kev phom sij; Tus nqi ntws tsawg dhau, tsis muaj txiaj ntsig thiab tsis muaj nyiaj txiag. Rau cov khoom uas muaj kuab heev thiab tawg, yuav tsum tau noj me me. Tus nqi ntws ntawm cov roj thiab cov kua dej nrog cov viscosity siab yog xaiv raws li viscosity, uas feem ntau yog 0.1 ~ 2m / s.
Feem ntau, tus nqi ntws tau paub, thiab tus nqi ntws tuaj yeem txiav txim siab empirically.
Tus nqi ntws ntawm ntau yam xov xwm tau qhia hauv Table 2-2. Lub nominal txoj kab uas hla ntawm lub valve tuaj yeem xam los ntawm tus nqi ntws thiab tus nqi ntws.
Covvalvetxoj kab uas hla yog tib yam, nws cov qauv sib txawv, thiab cov kua dej kuj sib txawv. Raws li cov xwm txheej zoo ib yam, qhov ntau dua qhov kev tiv thaiv coefficient ntawm lub valve, qhov ntau thiab qhov ntws ntawm cov kua los ntawm lub valve txo; Qhov me me ntawm qhov tsis kam coefficient ntawm lub valve, qhov tsawg dua tus nqi thiab cov dej ntws ntawm lub valve yuav txo qis.
