Ulwazi lweValve eqhelekileyo I

一 Ivalve yebhabhathane Idiskhi yevalve yebhabhathane yidiski, ejikeleza iaxis esitulweni. I-angle yokujikeleza yinqanaba lokuvula kunye nokuvala i-valve. Izibonelelo zayo zikhaphukhaphu, isakhiwo esilula, ukugcinwa kwezinto eziphathekayo xa kuthelekiswa nezinye iivalve, ukuvulwa ngokukhawuleza kunye nokuvala, ukusika kunye ne-throttling kunokusetyenziswa, ukuxhathisa ulwelo kuncinci, ukusebenza kukusindisa abasebenzi, kunokwenziwa kwikhariba enkulu. Iivalvu zebhabhathane zisetyenziswa kakhulu kwimibhobho yamanzi ashushu. Apho iivalve zebhabhathane zingasetyenziswa, kungcono ukuba ungasebenzisi iivalve zesango, kuba iivalve zebhabhathane zinoqoqosho ngakumbi kuneengcango zesango kwaye zinolawulo oluhle.二 Ivalve ye-diaphragm Ivalve ye-diaphragm isetyenziselwa ukwahlula indawo yomoya ngokucinezela ifilimu ye-elastomer ngokuqinileyo esitulweni ngesikhondo sevalvu. Ukujikeleza isondo lesandla kunokuqhuba isikhondo phezulu nasezantsi, ukuze i-diaphragm ishiye isihlalo ukuze uvule ivalve okanye wenze i-diaphragm icinezele ngokuqinileyo kwisitulo ukuvala ivalve. Izihlandlo zokusetyenziswa kwayo ngamanzi acocekileyo kakhulu, amanzi acocekileyo kakhulu akafuni i-engile efileyo kumbhobho wokuhamba; okwesibini, kukho ukungcola kwamanzi amdaka, isisombululo, njl., i-valve yebhola ye-particle kulwelo kulula ukuyinxiba kwaye ikrazule kwaye ivuze, ukuvalwa okuphezulu kunye nokusezantsi kwevalve ye-diaphragm kuphephe kakhulu le ngxaki, kwaye i-diaphragm inokutshintshwa emva kwexesha elide- ukusetyenziswa kwexesha.三 Ivalve ye-engile Umzimba wevalvu e-angular ujonge ekunene, umzimba wevalvu unesihlalo kunye nomphezulu wokutywina, ngokubanzi kwicala elisezantsi ngaphakathi nangaphandle. Imodeli esebenzayo ineenzuzo zesakhiwo esilula kunye nesiphumo esihle sokutywinwa. Ngomsebenzi wokuzihlambulula, umzimba we-valve awulula ukuqokelela ukungcola, awufanelekanga ukuplaga, ulungele ukulawula imidiya ye-viscosity ephezulu, ukuhluka koxinzelelo oluphezulu kunye neendaba eziqulethe izinto ezimisiweyo kunye ne-particulate matter. Ukungalungi kukuba ithande ukungazinzi kwi-valve core oscillation.四 iValve yokulawula ifilimu yomoya I-actuator yevalve yokulawula ifilimu yomoya ineziphumo ezihle nezibi. Isiphumo esihle kukuba xa uxinzelelo lukhula, i-valve stem ihla, kwaye uxinzelelo lungena kwigumbi lefilimu ngaphezu kwe-diaphragm edibeneyo. Ukusabela kuthetha ukuba xa uxinzelelo lukhula, isiqu sevalve sinyukela phezulu, kwaye uxinzelelo luyigumbi lefilimu phantsi kwediaphragm edibeneyo.
