A ivalve yonyawoyikhangela ivalveoko kuvumela kuphela ukuhamba kwicala elinye. Ivalve yeenyawo isetyenziswa apho kufuneka impompo, njengaxa amanzi efuna ukutsalwa kwiqula elingaphantsi komhlaba. Ivalve yeenyawo igcina impompo ivuliwe, ivumela amanzi ukuba angene ngaphakathi kodwa ingawavumeli ukuba abuyele umva, iyenze ilungele ukusetyenziswa kumachibi, amachibi kunye namaqula.

Isebenza njani ivalve yonyawo
Njengevalve evumela kuphela ukuhamba kwendlela enye, ivalve yonyawo ivula indlela enye kwaye ivale xa ukuhamba kukwicala elichaseneyo. Oku kuthetha ukuba kwizicelo ezifana namaqula, amanzi anokukhutshwa kuphela equleni. Nawaphi na amanzi ashiywe kumbhobho akavumelekanga ukuba abuyele emva kwivalve ukuya equleni. Makhe sihlolisise le nkqubo.

Kwimithombo yamanzi aphantsi komhlaba angenzulu, ukusetyenziswa kweevalvu zeenyawo kubandakanya oku kulandelayo:

Okokuqala, qwalasela indawo yevalve yonyawo. Ifakwe ekupheleni kokuqokelela kombhobho (isiphelo kwiqula apho kukhutshwa khona amanzi). Ibekwe kufuphi nomzantsi wequla.
Xa ipompo isebenza, ukufunxa kwenziwa, ukutsala amanzi ngombhobho. Ngenxa yoxinzelelo lwamanzi angenayo, i-valve ephantsi ivula xa amanzi ephuma phezulu.
Xa impompo icinyiwe, uxinzelelo oluphezulu luyayeka. Xa oku kusenzeka, umxhuzulane uya kusebenza kumanzi ashiywe kumbhobho, uzama ukuwubuyisela ezantsi equleni. Nangona kunjalo, ivalve yonyawo iyayithintela le nto ukuba yenzeke.
Ubunzima bamanzi kumbhobho butyhala ivalve esezantsi ezantsi. Ngenxa yokuba ivalve esezantsi ikwindlela enye, ayivuleki ijonge ezantsi. Endaweni yoko, uxinzelelo oluvela emanzini luvala ivalve ngokuqinileyo, luthintele nakuphi na ukubuyela umva equleni kunye nokusuka kwimpompo ukuya kwi-sump.

Kutheni ufuna ivalve yonyawo?
Iivalvu zeenyawo ziluncedo njengoko zithintela umonakalo onokwenzeka kwimpompo ngenxa yokungasebenzi kunye nokuyeka ukuchitha amandla.

Ezi zivalo ziyinxalenye ebalulekileyo yayo nayiphi na inkqubo yokumpompa. Lo mzekelo ungasentla uchaza indlela ivalve yonyawo esebenza ngayo kwinqanaba elincinci kakhulu. Qwalasela impembelelo yokungasebenzisiivalve yonyawokwiimeko ezinkulu, eziphezulu.

Kwimeko yokupompa amanzi kwi-sump yomhlaba kwi-tank phezulu kwesakhiwo, kuyimfuneko ukusebenzisa ipompo yombane enamandla. Njengemizekelo, ezi mpompo zisebenza ngokubanzi ngokwenza ukufunxa okunyanzela amanzi ukuba anyuke ngemibhobho ukuya kwitanki efunwayo.

Xa ipompo isebenza, kukho ikholamu yamanzi rhoqo kumbhobho ngenxa yokufunxa okwenziwayo. Kodwa xa impompo icinyiwe, ukufunxa kuphelile kwaye umxhuzulane uchaphazela ikholamu yamanzi. Ukuba i-valve yeenyawo ayifakwanga, amanzi aya kuhamba kumbhobho aze abuyele kumthombo wawo wokuqala. Imibhobho ayiyi kuba namanzi, kodwa izaliswe ngumoya.

Emva koko, xa impompo iphinda ivuliwe, umoya okumbhobho uvala ukuhamba kwamanzi, kwaye nokuba impompo ivuliwe, amanzi akayi kuhamba kumbhobho. Xa oku kusenzeka, kunokubangela idling kwaye, ukuba ayilungiswanga ngokukhawuleza, inokonakalisa impompo.

Ivalve engezantsi iyisombulula ngempumelelo le ngxaki. Xa impompo icinyiwe, ayivumeli nakuphi na ukuphuma kwamanzi ngasemva. Umpompo uhlala ulungele ukusetyenziswa okulandelayo.

Injongo yevalve yonyawo
Ivalve yonyawo yivalve yokukhangela esetyenziswa ngempompo. Zisetyenziswa kwiimeko ezahlukeneyo ezijikeleze ikhaya kunye nakwezinye iinkqubo zoshishino. Izivalo zeenyawo zingasetyenziswa kunye neempompo ezimpompa ulwelo (ezibizwa ngokuba ziimpompo zehydraulic) (ezifana namanzi) okanye usetyenziso lwamashishini (olufana neegesi) (ezibizwa ngokuba ziimpompo zomoya).

Ekhaya, iivalve zeenyawo zisetyenziswa kumachibi, amachibi, amaqula, nakuyo nayiphi na enye indawo enempompo. Kwiimeko zoshishino, ezi zivalo zisetyenziselwa iimpompo zamanzi amdaka, iimpompo zokungenisa umoya ezisetyenziswa kwimilambo kunye namachibi, imigca yokuqhawula umoya kwiilori zorhwebo, kunye nezinye izicelo apho iipompo zisetyenziswa khona. Basebenza kanye kwindawo yoshishino njengoko besenza kwidama elingasemva kwendlu.

Ivalve yonyawo yenzelwe ukugcina impompo iphambili, ivumela ulwelo ukuba lungene ngaphakathi, kodwa lungaphumi. Kukho izihluzi ezivala ukuvulwa kwevalve kwaye zinokuvala emva kwexeshana - ngakumbi ukuba zisetyenziselwa ukutsala amanzi equleni okanye echibini. Ngoko ke, kubalulekile ukucoca rhoqo i-valve ukuyigcina isebenza ngokufanelekileyo.

Khetha ivalve yonyawo lwasekunene
ivalve yonyawo lobhedu olusecaleni

Ivalve yeenyawo iyafuneka kwiimeko ezininzi. Nanini na xa kukho isicelo esifuna ukuhamba kolwelo unidirectional, ivalve yeenyawo iyafuneka. Ivalve yenyawo esemgangathweni inceda ukonga amandla kwaye ikhusele impompo emonakalweni, yandisa ubomi bayo bonke. Khumbula ukuba kubalulekile ukusebenzisa eyona valve yeenyawo esemgangathweni kangangoko, njengoko kunokuba nzima ukufikelela xa sele ifakiwe.
