Valve flow flow features curve uye classification valve flow features, iri muvharuvhu kumagumo ese emusiyano wepressure inoramba iine mamiriro ezvinhu, iyo yepakati inoyerera kuburikidza nevhavha hama inoyerera uye kuvhura kwayo pakati pehukama pakati pekuyerera kwemaitiro evharuvhu chinhu chakakosha chehunyanzvi zviratidzo uye parameter muchirongwa chekushandisa vharafu kuita sarudzo chaiyo ine kukosha kwakakosha.

Chimiro chevharuvhu chinoyerera chinogona kutsanangurwa se: kuyerera kwehukama hwepakati inodzorwa kuburikidza nevharuvhu, uye hukama pakati pekuvhurwa kwehama (chikafu chinosimuka) chevharuvhu nevharuvhu kunonzi kuyerera hunhu hwevhavha inotonga. Kazhinji kutaura, yakakamurwa kuita mhando ina: mutsara wakatwasuka, wakaenzana muzana (logarithm), parabola uye nekukurumidza kuvhurika! Tsanangudzo chaiyo uye zvakanakira ndezvizvi:

Kutanga, chimiro chemutsara chinoreva hukama hwemutsara pakati pehuwandu hwekuyerera kwevharuvhu uye kuvhurwa kwehama, ndiko kuti, kuenderera kwekuchinja kwekuyerera kunokonzerwa nekushandurwa kwekuvhurwa kweyuniti. Kufamba kwakabatana kwemaitiro emutsara kuri muhukama hwakatwasuka nechiyero chekuyerera. Kuchinja kwehuwandu hwekuyerera kunokonzerwa nekushandurwa kwechikwata chechikwata chinogara chiripo. Kana chiyero chekuyerera chiri chikuru, kukosha kwehuwandu hwehuwandu hwehuwandu hunochinja hudiki, uye huwandu hwekuyerera hushoma, kukosha kwehuwandu hwehuwandu hunochinja zvikuru.

Chechipiri, iyo yakaenzana muzana yemaitiro (logarithm) inoreva kuti kutenderera kunoenderana nekushanduka kunokonzerwa nekushandurwa kwekuvhura kweyuniti kunoenzana nechiyero chekuyerera kweiyo poindi, ndiko kuti, iyo amplification coefficient yevhavha yekudzora iri kushanduka, uye inowedzera nekuwedzera kweiyo kuyerera. Chirwere chehukama uye kuyerera kwehuwandu hwehuwandu hwehuwandu hwehuwandu huri muhutano hwemutsara, uye kuchinja kwekuyerera kunokonzerwa nekushandurwa kwechikwata chechikwata pane imwe neimwe nzvimbo yekurohwa kunoenzanirana nehuwandu hwekuyerera panguva ino, uye chikamu chekuchinja kwekuyerera kwakaenzana. Nokudaro, ruzivo rwayo nderokuti kuyerera kuduku, kushanduka kushanduka kuduku, uye kana kuyerera kwakakura, kuyerera kunoshanduka zvikuru, ndiko kuti, ine kururamisa kwakafanana mukuzarura kwakasiyana.

Chetatu, hunhu hweparabolic (parabolic character) hunoreva kushanduka kwechikafu chinoitwa neshanduko yekuvhurika kwechikamu muchikamu chakananga kumudzi wepakati wekuyerera ukoshi hwepano. Muyero wekuyerera unosiyana zvichienderana nemativi maviri esitiroko, ane humiro hwepakati hwemutsara uye yakaenzana muzana maitiro.

Chechina, kukurumidza kuvhura kuyerera hunhu kunoreva kuyerera kwakakura kana kuvhurwa kuri kudiki, nekuwedzera kwekuvhura, chiyero chekuyerera chinogona nekukurumidza kusvika pakakwirira, uyezve kuwedzera kuvhura, kuyerera kwekuchinja kudiki kwazvo, saka kunonzi kukurumidza kuvhura hunhu.

Kuyerera kwemaitiro e diaphragm mavharuvhu ari padyo neanokurumidza kuvhura maitiro, maitiro ekuyerera kweshavishavi mavharuvhu ari pedyo neakaenzana muzana maitiro, kuyerera kwemaitiro emagedhi mavharuvhu ane mutsara maitiro, kuyerera kwemaitiro ebhora mavharuvhu mitsara yakatwasuka pakati pekuvhura nekuvhara nhanho, uye yakaenzana muzana maitiro ari pakati pekuvhura.

Kazhinji, bhora mavharuvhu uyebutterfly mavharuvhuhaiwanzo kushandiswa kugadzirisa, kana yakashandiswa kugadzirisa, asiwo munyaya yekuvhura kudiki kuita basa mumutemo, kazhinji inogona kuverengerwa semhando yekukurumidza kuvhura, uye iyo chaiyo semutemo weakawanda epasi globe vharafu, iyo yevhavha yemusoro inogadziriswa kuita senge parabolic cone, spherical, nezvimwewo, ichashandisa akasiyana curve maitiro, anowanzo shandiswa seyakanyanya kurongeka maitiro, anowanzo shandiswa seyakanyanya kurongeka hunhu.
