Iinkqubo zokucima umlilo zibalulekile ekukhuseleni ubomi kunye nepropathi kwiingozi zomlilo. Inxalenye ebalulekileyo yezi nkqubo luluhlu lweevalvu ezisetyenziselwa ukulawula, ukulawula, kunye nokuhamba ngokuthe ngqo kwamanzi. Ukuqonda iintlobo ezahlukeneyo zeevalvu kunye neendima zazo ngaphakathi kwenkqubo yokukhusela umlilo kubalulekile kuyilo kunye nokugcinwa. Apha ngezantsi, siza kuphonononga ezinye zevalufa eziqhelekileyo ezisetyenziswa kwiinkqubo zokulwa nomlilo.
1. Iivalvu zeSango
Iivalve zesango ziphakathi kwezona zisetyenziswa kakhulu kwiinkqubo zokukhusela umlilo. Ezi zivalo zisebenza ngokuphakamisa isango (icwecwe elisicaba okanye elimise okwe wedge) ngaphandle kwendlela yokuhamba kwamanzi. Xa zivuleke ngokupheleleyo, iivalvu zesango zivumela ukuhamba kwamanzi okungathintelekiyo, nto leyo ezenza zibe zilungele ukwahlula amacandelo othungelwano lwemibhobho yokukhusela umlilo. Ngokuqhelekileyo zisetyenziswa kwizicelo apho ivalve ivuleke ngokupheleleyo okanye ivalwe ngokupheleleyo. Iivalvu zesango, ngakumbi ezo zine-OS & Y (Isikrufu sangaphandle kunye neYoke), zikhethwa ngenxa yokuba isimo sazo esivulekileyo okanye esivaliweyo sinokumiselwa ngokulula ngokuma kwesikrufu kunye nedyokhwe.
2. Jonga iiValves
Iivalvu zokukhangela zibalulekile ekuthinteleni ukubuya umva kwiinkqubo zokulwa nomlilo. Zivumela amanzi ukuba ahambe kwicala elinye kuphela, azivale ngokuzenzekelayo xa amanzi ebuyela umva. Lo msebenzi ubalulekile ekugcineni ingqibelelo yenkqubo kunye nokuthintela ukungcoliseka okanye umonakalo. Iivalve zokujonga i-Swing, kunye nediski yazo enehenjisi ejikelezayo xa amanzi ehamba ngendlela echanekileyo, isetyenziswa ngokuqhelekileyo kwiinkqubo zokukhusela umlilo ngenxa yokuthembeka kunye noyilo olulula.
3. Iivalvu zeBhola
Iivalvu zebhola zisebenzisa idiski engqukuva ("ibhola") ukulawula ukuhamba kwamanzi. Xa umngxuma webhola ulungelelaniswa nolwalathiso lokuhamba, i-valve ivulekile, kwaye xa ibhola lijikeleza i-90 degrees, i-valve ivaliwe. Iivalve zebhola ziyaziwa ngokuhlala kwazo kunye nezakhono zokutywina ezigqwesileyo, ezibenza zibe zilungele iimeko zokuvala ngokukhawuleza. Zihlala zisetyenziselwa kwiibhobho ezincinci ze-diameter ngaphakathi kweenkqubo zokukhusela umlilo kwaye zixabiswa ngokusebenza kwazo ngokukhawuleza kunye nokuthembeka.
4. Iivalve zebhabhathane
Iivalvu zebhabhathane lolunye uhlobo lwevalve yekota esebenzisa idiski ejikelezayo ukulawula ukuhamba. Zithandwa kakhulu kwiinkqubo zombhobho wobubanzi obukhulu ngenxa yoyilo lwazo oludibeneyo kunye nokusebenza ngokulula. Iivalvu zebhabhathane ngokuqhelekileyo zikhaphukhaphu kwaye zingabizi kakhulu kuneengcango zesango okanye zeglowubhu, zizenza zibe lukhetho olungabizi kakhulu lokulawula ukuhamba kwamanzi kwiinkqubo zokulwa nomlilo. Zihlala zisetyenziswa njengezivalo zodwa kwiinkqubo zokutshiza umlilo, apho imiqobo yendawo kunye neendleko ziqwalaselwa.
Ukuqukumbela
Uhlobo ngalunye lwe-valve kwinkqubo yokulwa nomlilo lusebenza ngenjongo ethile, igalelo ekukhuseleni ngokubanzi kunye nokusebenza kakuhle kwenkqubo. Ukuqonda iindima kunye nokusebenza kwezi zivalo kunokunceda ekuyilweni, ukukhetha, kunye nokugcinwa kweenkqubo zokukhusela umlilo. Ngokuqinisekisa ukuba iivalve ezifanelekileyo zisetyenziswa kwaye zigcinwe ngokufanelekileyo, umntu unokunyusa kakhulu ukusebenza kwenkqubo yokucima umlilo, ekugqibeleni ekhusela ubomi kunye nepropati kwimiphumo eyingozi yomlilo.
