Ivalve yeSango le-GB

Ivalve yesango ibhekisa kwivalve yolawulo esona siqwenga sokuvala (isango) sihamba kwicala elithe nkqo ecaleni kombindi wepaseji.Kwimibhobho, umlawuli we-brake angasetyenziselwa kuphela ukuvulwa ngokupheleleyo kunye nokuvalwa ngokupheleleyo, kwaye akanakusetyenziselwa ukulawulwa kunye ne-throttling.

Xa isango livaliwe, indawo yokutywina inokutywinwa kuphela ngoxinzelelo oluphakathi, oko kukuthi, indawo yokutywina yeplate icinezelwe kwisihlalo sevalve kwelinye icala ngoxinzelelo oluphakathi ukuqinisekisa ukutywinwa kwendawo yokutywina, okubizwa ngokutywinwa okumhlophe.Uninzi lwabalawuli besango bamkela ukutywinwa okunyanzeliswayo, oko kukuthi, xa i-valve ivaliwe, amandla angaphandle afunekayo ukunyanzela inkunzi yegusha icinezele ukulungelelanisa isihlalo ukuze kuqinisekiswe ukuqina kwendawo yokutywina.

Xa uvula i-valve, kwaye ukuphakama kwenkunzi yegusha kufana ne-1: 1 amaxesha ububanzi be-valve yokulawula, i-valve ye-fluid ihlanjululwa ngokupheleleyo, kodwa esi sikhundla asikwazi ukujongwa ngexesha lokusebenza.Ekusetyenzisweni okwenyani, i-vertex ye-valve pole ithathwa njengophawu, oko kukuthi, indawo apho ingenako ukuvulwa ithathwa njengendawo evulekileyo epheleleyo.Ukuze kuqwalaselwe umcimbi wokutshixa ngenxa yokutshintsha kweqondo lokushisa, ngokuqhelekileyo ukubuyisela umva i-1/2 ukuya kwi-1 xa i-valve ivulwa kwindawo yenqaku lenqaku njengendawo yokuvula ngokupheleleyo i-valve.Ngoko ke, indawo evulekileyo epheleleyo yevalve imiselwe yindawo yenkunzi yegusha (oko kukuthi, ukubetha).
