Abakhiqizi bama-valve okuhlola bakholelwa ukuthi ama-valve okuhlola avamile avala ngokushesha futhi athambekele ekusandoni samanzi, okuphumela ekwenyukeni okungazelelwe kokucindezela, ukulimala kwamapayipi nezinto zokusebenza, nomsindo omkhulu.I-valve yokuhlola yokuvala kancane kancane ixazulula izinkinga ezibangelwa ukuvala ngokushesha kwama-valve okuhlola avamile.Isetshenziswa ekuhlinzekeni kwamanzi okuqondile kanye nezinhlelo zokudonsa amanzi ezimbonini nasezimayini kanye nezakhiwo eziphakeme kakhulu, zinganciphisa ukwenzeka kwesando samanzi nesando samanzi futhi kufinyelele umphumela wokuvala ngokuphephile.
1. Izici zesakhiwo sevalvu yokuhlola evala kancane ukumelana ne-micro-resistance:
I-valve eyodwa ifakwe phambi kwe-valve, futhi i-valve eyodwa ifakwe ngemuva kwe-valve, ekulungele ukulungiswa.Faka isihlungi phambi kwe-valve ukuvimbela ukungcola ohlelweni lwamapayipi ekungeneni ku-valve yokuhlola.Abakhiqizi be-valve yokuhlola bakholelwa ukuthi i-valve yokuhlola evala kancane kufanele ifakwe ivundlile.Uma i-valve ifakwe emthonjeni, kufanele kube nendawo yokulungisa.I-valve yokukhipha umoya othomathikhi kufanele ifakwe epayipini ngokuvumelana nemininingwane efanele ukuze kuqinisekiswe ukugeleza okuqhubekayo kwekholomu yamanzi.
2. Umgomo wokusebenza wevalvu yokuhlola evala kancane ukumelana ne-micro-resistance:
Lapho iphampu yamanzi iqalwa: umenzi we-valve yokuhlola ukholelwa ukuthi ukucindezela endaweni yokungena kwe-valve kubangela ukuba i-disc ye-valve ivuleke ngokushesha ngokumelene namandla asentwasahlobo, futhi okuphakathi nendawo ekungeneni kwe-valve enkulu ingena ekamelweni eliphezulu le-diaphragm nge-valve yenaliti. kanye ne-valve yokuhlola.Lungisa ukuvuleka kwe-valve yenaliti, ukuze okuphakathi nendawo okungena ekamelweni eliphezulu le-diaphragm kusebenze kupuleti lokucindezela kwe-diaphragm, futhi amandla okusabela akhiqizwa kudiski ye-valve ukuqinisekisa ukuthi i-disc ye-valve ivuleka kancane.Lungisa ukuvulwa kwe-valve yenaliti endaweni yokungena ye-valve eyinhloko, lawula isivinini sokuvula se-valve, futhi uqinisekise ukuthi isikhathi sokuvula i-valve eyinhloko side kunesikhathi sokuqala se-pump motor, ukuze iphampu iqale. ngaphansi komthwalo okhanyayo futhi uvimbele injini yokuqala yamanje ekubeni inkulu kakhulu.
Lapho ipompo yamanzi ivaliwe: umenzi we-valve yokuhlola ukholelwa ukuthi ukucindezela endaweni yokungena kwe-valve kuncipha ngokuzumayo, futhi i-valve flap izovala ngokuzumayo ngaphansi kwengcindezi ekuphumeni, okuholela ekukhuphukeni okungazelelwe kokucindezela endaweni yokuphuma kwe-valve.Ngalesi sikhathi, kulula ukwenzeka isando samanzi, sibangele ukulimala kwepayipi nezinto zokusebenza ezingemuva kwevalvu, futhi sikhiphe umsindo omkhulu.
Umkhiqizi we-valve yokuhlola ukholelwa ukuthi ngenxa yokuthi uhlelo lokubuyisela lufakwe ekugcineni kwe-valve, i-medium ngemva kokuba i-valve ingena ekamelweni eliphezulu le-diaphragm nge-valve yebhola.Ngenxa yomsebenzi wokuhlola we-valve yokuhlola, i-medium ayikwazi ukungena ekugcineni kwe-inlet, futhi igumbi eliphansi le-diaphragm libuye ligcwaliswe phakathi.Nakuba ingcindezi ye-medium ekamelweni eliphezulu ikhuthaza ukuvala i-valve flap, i-medium ekamelweni elingaphansi ayikwazi ukukhishwa ngokushesha ngaphansi kwesenzo sokugubha imbobo encane yesihlalo se-diaphragm, okuholela enkambisweni yokuvimbela, okuvimbela isivinini sokuvala se-valve flap futhi sifinyelela ukuvala kancane.Umthelela oyisimungulu uvimbela ukwenzeka kwesando samanzi.Ngokulungisa ukuvuleka kwe-valve yebhola, isivinini sokuvala se-valve disc (okungukuthi isikhathi sokuvala se-valve) singalawulwa ngempumelelo.
Umkhiqizi we-valve yokuhlola ukholelwa ukuthi i-valve yokuhlola evala kancane kancane inezici zobuchwepheshe zokuvula kancane nokuvala kancane nokuqeda isando samanzi, eqaphela ukuqala komthwalo wokukhanya wepompo futhi ivimbele ukwenzeka kwesando samanzi lapho iphampu. imisiwe.Ngemuva kokuthi injini yephampu iqalisiwe, i-valve izovuleka futhi ivale ngokuzenzakalelayo ngokuya ngohlelo lokusebenza lwephampu.I-valve yokuhlola isho i-valve evula ngokuzenzakalelayo futhi ivale i-valve flap ngokugeleza kwe-medium ngokwayo ukuvimbela ukubuyela emuva kwe-medium.
Abakhiqizi be-valve yokuhlola bakholelwa ukuthi i-valve yokuhlola i-valve ezenzakalelayo, futhi umsebenzi wayo oyinhloko ukuvimbela ukubuyela emuva kwe-medium, ukuvimbela ukujikeleza okuphambene kwepompo kanye ne-drive motor, nokukhulula okuphakathi esitsheni.Amavalvu okuhlola angasetshenziswa futhi ekunikezeni amapayipi amasistimu asizayo lapho ukucindezela kungase kukhuphuke ngaphezu kokucindezela kwesistimu.Ama-valve okuhlola angahlukaniswa abe ama-valve okuhlola ama-swing (ajikelezayo ngokuya phakathi nendawo ye-gravity) kanye nama-valve okuhlola okuphakamisa (ahamba nge-eksisi).
