A i-valve yonyawoyin ahlola i-valvelokho kuvumela kuphela ukugeleza ohlangothini olulodwa. I-valve yonyawo isetshenziswa lapho kudingeka khona iphampu, njengalapho amanzi edinga ukudonswa emthonjeni ongaphansi komhlaba. I-valve yonyawo igcina iphampu ivuliwe, ivumela amanzi ukuthi agelezele ngaphakathi kodwa ingawavumeli ukuthi abuyele emuva, okuyenza ilungele ukusetshenziswa emachibini, emachibini nasemithonjeni.

Isebenza kanjani i-valve yonyawo
Njenge-valve evumela ukugeleza kwendlela eyodwa kuphela, i-valve yonyawo ivula indlela eyodwa futhi ivale lapho ukugeleza kuphambene. Lokhu kusho ukuthi ekusetshenzisweni okufana nemithombo, amanzi angakhishwa kuphela emthonjeni. Noma yimaphi amanzi asele epayipini awavunyelwe ukuthi abuyele emuva ngevalvu eya emthonjeni. Ake siyibhekisise le nqubo.

Emithonjeni yamanzi angaphansi angajulile, ukusetshenziswa kwama-valve onyawo kuhilela lokhu okulandelayo:

Okokuqala, cabangela isikhundla se-valve yonyawo. Ifakwe ekugcineni kweqoqo lombhobho (ukuphela emthonjeni lapho kukhishwa khona amanzi). Itholakala eduze naphansi komthombo.
Lapho ipompo isebenza, ukumuncwa kwenziwa, kudonswa amanzi ngepayipi. Ngenxa yokucindezela kwamanzi angenayo, i-valve engezansi iyavuleka lapho amanzi egeleza phezulu.
Lapho iphampu icishiwe, umfutho okhuphukayo uyama. Uma lokhu kwenzeka, amandla adonsela phansi azosebenza emanzini asele epayipini, ezama ukuwahlehlisa abuyele emthonjeni. Nokho, i-valve yonyawo ivimbela lokhu ukuthi kungenzeki.
Isisindo samanzi epayipini siphusha i-valve engezansi phansi. Ngenxa yokuthi i-valve engezansi iyindlela eyodwa, ayivuleki iye phansi. Esikhundleni salokho, ukucindezela okuvela emanzini kuvala i-valve ngokuqinile, ukuvimbela noma yikuphi ukugeleza okubuyela emuva emthonjeni nokusuka empompini kubuyele ku-sump.

Kungani udinga i-valve yonyawo?
Ama-valve ezinyawo ayazuzisa njengoba avimbela ukulimala okungenzeka kwipompo ngenxa yokungenzi lutho futhi ayeke ukumosha amandla.

Lawa ma-valve ayingxenye ebalulekile yanoma yiluphi uhlelo lokumpompa. Isibonelo esingenhla sichaza ukuthi i-valve yonyawo isebenza kanjani esikalini esincane kakhulu. Cabangela umthelela wokungasebenzisii-valve yonyawoezimweni ezinkulu, ezisezingeni eliphezulu.

Endabeni yokupompa amanzi kusuka ku-sump emhlabathini kuya ethangini elingaphezulu kwesakhiwo, kuyadingeka ukusebenzisa ipompo enamandla kagesi. Njengezibonelo, lawa maphampu ngokuvamile asebenza ngokudala ukumunca okuphoqa amanzi ukuthi akhuphuke ngamapayipi aye ethangini elifunekayo.

Lapho ipompo isebenza, kunekholomu yamanzi ehlala njalo epayipini ngenxa yokumunca okukhiqizwa. Kodwa lapho iphampu icishiwe, ukumunca akusekho futhi amandla adonsela phansi athinta ikholomu yamanzi. Uma i-valve yonyawo ingafakiwe, amanzi azogeleza phansi epayipini futhi abuyele emthonjeni wawo wokuqala. Amapayipi azobe engenawo amanzi, kodwa agcwaliswe umoya.

Khona-ke, lapho iphampu ivuliwe futhi, umoya osepayipini uvimba ukugeleza kwamanzi, futhi ngisho noma iphampu ivuliwe, amanzi ngeke ageleze epayipini. Uma lokhu kwenzeka, kungabangela idling futhi, uma kungabhekwanga ngokushesha, kungalimaza iphampu.

I-valve engezansi ixazulula ngempumelelo le nkinga. Uma iphampu ivaliwe, ayikuvumeli ukugeleza kwamanzi emuva. Iphampu ihlala ilungele ukusetshenziswa okulandelayo.

Inhloso ye-valve yonyawo
I-valve yonyawo iyivalvu yokuhlola esetshenziswa nepompo. Asetshenziswa ezimweni ezahlukahlukene ezizungezile ekhaya nakwezinye izinhlelo zokusebenza zezimboni. Amavalvu ezinyawo angasetshenziswa namaphampu ampompa uketshezi (okuthiwa amaphampu adonsa amanzi) (njengamanzi) noma izinto ezisetshenziswa ezimbonini (njengamagesi) (okuthiwa amaphampu womoya).

Ekhaya, ama-valve onyawo asetshenziswa emachibini, emachibini, emithonjeni, nanoma yikuphi okunye okunepompo. Ezilungiselelweni zezimboni, lawa ma-valve asetshenziswa kumaphampu okuthuthwa kwendle, amaphampu okungenisa umoya asetshenziswa emifuleni nasemachibini, imigqa yamabhuleki omoya amaloli entengiso, nezinye izinhlelo zokusebenza lapho kusetshenziswa khona amaphampu. Basebenza kahle endaweni yezimboni njengoba besebenza echibini elingemuva kwendlu.

I-valve yonyawo iklanyelwe ukugcina iphampu igxilile, ivumela uketshezi ukuthi lugeleze ngaphakathi, kodwa lungaphumi. Kunezihlungi ezivala ukuvuleka kwe-valve futhi zingavala ngemva kwesikhashana - ikakhulukazi uma zisetshenziselwa ukukhipha amanzi emthonjeni noma echibini. Ngakho-ke, kubalulekile ukuhlanza njalo i-valve ukuze uyigcine isebenza kahle.

Khetha i-valve yonyawo lwesokudla
i-valve yonyawo lwethusi ohlangothini

I-valve yonyawo iyadingeka ezimweni eziningi. Noma kunini lapho kunesicelo esidinga ukugeleza kwe-liquid unidirectional, i-valve yonyawo iyadingeka. Ivalvu yonyawo yekhwalithi isiza ukonga amandla futhi ivikele iphampu emonakalweni, yelule isikhathi sayo sonke sempilo. Khumbula ukuthi kubalulekile ukusebenzisa ivalvu yonyawo yekhwalithi engcono kakhulu ngangokunokwenzeka, njengoba kungaba nzima ukufinyelela lapho isifakiwe.
