Iimpawu zokuhamba kwevalve ijika kunye neempawu zokuhamba kwevalve, ikwivalve kwiziphelo zombini zomahluko woxinzelelo ihlala ikwimeko engaguqukiyo, ukuhamba okuphakathi kwi-valve yesalamane kunye nokuvulwa kwayo phakathi kobudlelwane phakathi kweempawu zokuhamba kwevalve luphawu olubalulekileyo lwezalathi zobugcisa kunye neeparameters kwinkqubo yesicelo sevalve ukwenza ukhetho oluchanekileyo lubaluleke kakhulu.

Uphawu lokuhamba kwevalve lunokuchazwa ngolu hlobo: ukuhamba okuzalanayo kwendawo elawulwayo ngevalve, kunye nobudlelwane phakathi kokuvula okuzalanayo (ukufuduswa okuzalanayo) kwevalve kunye nevalve ibizwa ngokuba luphawu lokuhamba lwevalve elawulayo. Ngokuqhelekileyo, yahlulwe yaba ziindidi ezine: umgca othe ngqo, ipesenti elinganayo (logarithm), iparabola kunye nokuvula ngokukhawuleza! Inkcazo ethile kunye neenzuzo zezi zilandelayo:

Okokuqala, uphawu lomgca lubhekiselele kubudlelwane bomgca phakathi kwesantya sokuhamba kwe-valve kunye nokuvulwa okuhambelanayo, oko kukuthi, ukuguquka kokutshintsha kokuhamba okubangelwa ukuguqulwa kweyunithi yokuvula. Ukuhamba okuhambelanayo kweempawu zomgca kubudlelwane bomgca othe ngqo kunye nesantya sokuhamba. Utshintsho kwisantya sokuhamba okubangelwa ukutshintshwa kweyunithi ye-stroke ihlala njalo. Xa isantya sokuhamba sikhulu, ixabiso elihambelanayo lezinga lokuhamba litshintsha lincinci, kwaye izinga lokuhamba lincinci, ixabiso elihambelanayo lexabiso lokuhamba litshintsha kakhulu.

Okwesibini, ipesenti elinganayo (i-logarithm) ithetha ukuba utshintsho oluhambahambayo olubangelwa utshintsho lokuvula iyunithi lulingana nesantya sokuhamba kwenqanaba, oko kukuthi, i-coefficient yokukhulisa i-valve yokulawula iyatshintsha, kwaye iyanda ngokunyuka kokuhamba okuhambelanayo. I-stroke ehambelanayo kunye nokuhamba okuhambelanayo kweempawu zeepesenti ezilinganayo azikho kubudlelwane bomgca, kwaye ukuguqulwa kokuhamba okubangelwa ukuguqulwa kweyunithi yeyunithi kwinqanaba ngalinye le-stroke lilingana nesantya sokuhamba kweli nqanaba, kwaye ipesenti yokutshintsha ukuhamba kuyalingana. Ngako oko, inzuzo yayo kukuba isantya sokuhamba sincinci, utshintsho lokuhamba luncinci, kwaye xa ukuhamba kukhulu, izinga lokuhamba litshintsha kakhulu, oko kukuthi, linokuchaneka kokulungelelaniswa okufanayo kwiindawo ezahlukeneyo zokuvula.

Okwesithathu, uphawu lwe-parabolic lubhekiselele kutshintsho lokuhamba okuhambelanayo okubangelwa ukuguqulwa kokuvulwa kweyunithi ngokulinganayo ngokuthe ngqo kwingcambu yesikwere sexabiso lokuhamba elihambelanayo le ngongoma. Izinga lokuhamba liyahluka ngokulinganayo kumacala amabini e-stroke, kunye neempawu eziqikelelwayo eziphakathi kweempawu zomgca kunye neepesenti ezilinganayo.

Okwesine, uphawu lokuhamba ngokukhawuleza lokuvula lubhekisela ekuhambeni okukhulu xa ukuvulwa kuncinci, kunye nokwanda kokuvula, izinga lokuhamba ngokukhawuleza linokufikelela kwinqanaba eliphezulu, kwaye emva koko kwandiswe ukuvuleka, utshintsho lokuhamba luncinci kakhulu, ngoko lubizwa ngokuba luphawu lokuvula ngokukhawuleza.

Iimpawu zokuhamba kweevalve ze-diaphragm zisondele kwiimpawu zokuvula ngokukhawuleza, iimpawu zokuhamba kweevalve zebhabhathane zisondele kwiimpawu zepesenti ezilinganayo, iimpawu zokuhamba kwee-valve zesango ziyimpawu ezihambelanayo, iimpawu zokuhamba kweevalve zebhola ziyimigca ethe tye kwinqanaba eliphakathi lokuvula kunye nokuvala, kunye neempawu zeepesenti ezilinganayo kwindawo yokuvula phakathi.

Ngokubanzi, iivalve zebhola kunyeiivalve butterflyzidla ngokungasetyenziselwa uhlengahlengiso, ukuba zisetyenziselwa uhlengahlengiso, kodwa nakwimeko yokuvula okuncinci ukudlala indima kulawulo, ngokubanzi zinokuhlelwa njengohlobo lokuvula ngokukhawuleza, kunye neyokwenyani njengommiselo wobuninzi bevalve yeglowubhu esisiseko, ukusetyenzwa kwentloko yevalve kwi-cone yeparabolic, spherical, njl.
