I-valve iyithuluzi eliwumshini lokulawula ukugeleza koketshezi noma igesi ekugelezeni kwenqubo.I-valve yokuphepha iwukwehluleka kokuvikela, inhloso yayo ukuqinisekisa ukuphepha kwepayipi.Isibonelo, i-valve yokukhulula ingcindezi (i-PRV) njengolunye uhlobo lwevalvu yokuphepha ededela ngokuzenzakalelayo okokusebenza kumkhumbi ocindezelayo, kubhayela, noma enye isistimu lapho ingcindezi noma izinga lokushisa lidlula umkhawulo osethiwe.

Imakethe yama-valve okuphepha ingahlukaniswa ngezinto ezibonakalayo, usayizi, imboni kanye nesifunda.Ngokwezinto ezahlukahlukene ezisetshenziswayo, imakethe yama-valve okuphepha ingahlukaniswa ngensimbi engagqwali, insimbi eyinsimbi, izinga lokushisa eliphansi, ingxubevange nezinye izinhlobo, ingasetshenziswa kabanzi kuwoyela negesi, amandla, amandla, amanzi kanye nokwelashwa kwamanzi angcolile, amakhemikhali, imithi. , izimayini zensimbi, izimboni zokudla neziphuzo.

Iqhaza elibalulekile le-valve yokuphepha enqubweni yezimboni, ukwanda kwesidingo embonini kawoyela negesi, kanye nokukhula kokukhiqizwa kwamandla enuzi yizici ezibalulekile zokukhuthaza ukukhula kwemakethe yamavalvu okuphepha.Imakethe yamavalve okuphepha ekhulayo iqhutshwa yisidingo esiqhubekayo sokushintsha ama-valve okuphepha kanye nokusetshenziswa kwamaphrinta e-3D emigqeni yokukhiqiza.Ngakolunye uhlangothi, izindleko eziphezulu zokukhiqiza zizothikameza ukwanda kwale makethe.

I-COVNA futhi ihlale ithuthukisa futhi isungula izinto ezintsha ukuze ikhiqize futhi inikeze amavalvu okuphepha ekhwalithi ephezulu ukuze andise imakethe yamazwe ngamazwe.
