UKUSETSHENZISWA KWE-VALVE

Ukuze kuhlangatshezwane nezidingo zohlelo lokuqoqa amanzi oluklanywe kahle, kusetshenziswa izinhlobo ezahlukene zamavalvu.Balawula lapho izinhlobo ezahlukene zamanzi zingaya khona futhi zingakwazi ukuya khona.Izinto zokwakha ziyahlukahluka ngokwemithetho yendawo, kodwa i-polyvinyl chloride (PVC), insimbi engagqwali, nethusi/ithusi yizona ezivame kakhulu.

Sengikushilo lokho, kukhona okuhlukile.Amaphrojekthi aklanyelwe ukuhlangabezana "Nenselelo Yokwakha Okuphilayo" adinga izindinganiso eziqinile zokwakha eziluhlaza futhi avimbele ukusetshenziswa kwe-PVC nezinye izinto ezibhekwa njengengozi emvelweni ngenxa yezinqubo zokukhiqiza noma izindlela zokulahla.

Ngaphezu kwezinto zokwakha, kunezinketho zokuklama nohlobo lwe-valve.Okunye kwalesi sihloko kubheka imiklamo evamile yesistimu yokuqoqa amanzi emvula kanye namanzi ampunga nokuthi zisetshenziswa kanjani izinhlobo ezahlukene zamavalvu kumklamo ngamunye.

Ngokuvamile, ukuthi amanzi aqoqiwe azophinde asetshenziswe kanjani nokuthi amakhodi endawo asetshenziswa kanjani kuzothinta uhlobo lwevalvu esetshenzisiwe.Elinye iqiniso elicutshungulwayo ukuthi inani lamanzi atholakalayo ukuze kuqoqwe lingase linganele ukuhlangabezana nezidingo zokuphinda zisetshenziswe ngo-100%.Kulesi simo, amanzi asekhaya (amanzi okuphuza) angase afakwe ohlelweni ukuze kulungiswe ukuntuleka.

Okukhathaza kakhulu izikhungo ezilawula impilo yomphakathi kanye namapayipi ukuhlukanisa imithombo yamanzi asekhaya ekuxhumekeni kwamanzi aqoqiwe kanye nokungcoliswa okungaba khona kwamanzi okuphuza asekhaya.

ISITOREJI/UKUNGCOLA

Ithangi lamanzi lansuku zonke lingasetshenziselwa ukugeza izindlu zangasese kanye neziqukathi zokubulala amagciwane ukuze kusetshenziswe ezinye izinto zokupholisa zombhoshongo.Ezinhlelweni zokuchelela, kuvamile ukumpompa amanzi ngokuqondile echibini ukuze aphinde asetshenziswe.Kulesi simo, amanzi angena ngokuqondile esinyathelweni sokugcina sokuhlunga kanye nokuthuthwa kwendle ngaphambi kokushiya ama-sprinklers wesistimu yokunisela.

Ama-valve ebhola ngokuvamile asetshenziselwa ukuqoqwa kwamanzi ngoba angavula futhi avale ngokushesha, abe nokusabalalisa okuphelele kokugeleza kwechweba kanye nokulahlekelwa kwengcindezi ephansi.Idizayini enhle ivumela okokusebenza ukuthi kube yedwa ukuze kulungiswe ngaphandle kokuphazamisa lonke uhlelo.Isibonelo, umkhuba ojwayelekile uwukusebenzisaama-valve ebholaemibhobho yethangi ukulungisa okokusebenza ezansi nomfula ngaphandle kokuthulula ithangi.Iphampu ine-valve yokuhlukanisa, evumela ukuthi iphampu ilungiswe ngaphandle kokukhipha wonke amapayipi.I-valve yokuvimbela ukuphuma emuva (hlola i-valve) ibuye isetshenziswe ohlelweni lokuzihlukanisa (Umfanekiso 3).

UKUVIMELA UKUNGCOLA/UKWELASHWA

Ukuvimbela ukubuyela emuva kuyingxenye ebalulekile yanoma yiluphi uhlelo lokuqoqa amanzi.Ama-valve okuhlola ayindilinga ngokuvamile asetshenziselwa ukuvimbela ukugeleza kwepayipi emuva lapho iphampu ivaliwe futhi umfutho wesistimu ulahlekile.Ama-valve okuhlola nawo asetshenziselwa ukuvimbela amanzi asekhaya noma amanzi aqoqiwe ukuthi angabuyeli emuva, okungabangela ukuthi amanzi angcole noma ahlasele lapho kungekho muntu owafuna khona.

Lapho iphampu yokulinganisa ingeza i-chlorine noma amakhemikhali odayi okwesibhakabhaka emugqeni ocindezelwe, kusetshenziswa ivalvu yokuhlola encane ebizwa ngokuthi i-injection valve.

I-wafer enkulu noma i-disc yokuhlola i-valve isetshenziswa nesistimu yokuchichima ethangini lokugcina ukuvimbela ukugeleza emuva kwendle kanye nokungena kwamagundane ohlelweni lokuqoqa amanzi.

17 sum water fig5 Amavalvu ovemvane asebenza ngesandla noma ngogesi asetshenziswa njengamavalvu okuvala amapayipi amakhulu (Umfanekiso 5).Ukufakwa ngaphansi komhlaba, ama-valve ovemvane asebenza ngegiya asetshenziswa ukuvala ukugeleza kwamanzi ethangini lamanzi, ngokuvamile elingabamba amakhulu ezinkulungwane zamalitha amanzi, ukuze iphampu emthonjeni omanzi ilungiswe ngokuphepha futhi kalula. .Isandiso se-shaft sivumela ukulawula ama-valve angaphansi komthambeko ukusuka ezingeni le-slope.

Abanye abaklami baphinde basebenzise ama-valve ovemvane ohlobo lwe-lug, angasusa amapayipi angezansi komfula, ukuze i-valve ibe ivalvu yokuvala.Lawa ma-valve butterfly ama-lug aboshelwe kuma-flange okukhwelana ezinhlangothini zombili zevalvu.(I-wafer butterfly valve ayiwuvumeli lo msebenzi).Qaphela ukuthi ku-Figure 5, i-valve nesandiso kutholakala emthonjeni omanzi, ngakho-ke i-valve ingakwazi ukuseviswa ngaphandle kwebhokisi le-valve.

Lapho izinhlelo zokusebenza ezisezingeni eliphansi ezifana nokugeleza kwethangi lamanzi zidinga ukushayela i-valve, i-valve kagesi ayiyona into esebenzayo ngoba i-actuator kagesi ivame ukuhluleka lapho kukhona amanzi.Ngakolunye uhlangothi, ama-valve womoya ngokuvamile awafakwa ngenxa yokushoda komoya ocindezelweyo.Amavalvu asebenza ngama-hydraulic (hydraulic) ngokuvamile ayisixazululo.I-solenoid yomshayeli kagesi etholakala ngokuphephile eduze kwephaneli yokulawula ingaletha amanzi acindezelwe ku-actuator evamise ukuvaleka ye-hydraulic, engavula noma ivale i-valve ngisho nalapho i-actuator icwile emanzini.Kuma-actuator asebenza ngogesi, ayikho ingozi yokuthi amanzi ahlangane ne-actuator, okuyisimo esinjalo ngama-activator kagesi.

Ekuphetheni
Amasistimu okusebenzisa kabusha amanzi esizeni awahlukile kwamanye amasistimu okumele alawule ukugeleza.Iningi lezimiso ezisebenza kuma-valve nezinye izinhlelo zokuhlanza amanzi ngomshini zivele zamukelwe ngezindlela ezahlukene ukuze kuhlangatshezwane nezidingo eziyingqayizivele zale nsimu evelayo yemboni yamanzi.Noma kunjalo, njengoba ikhwelo lezakhiwo ezizinzile likhula nsuku zonke, le mboni kungenzeka ibaluleke embonini yamavalvu.
