A ivalvu yonyawokuyintoivalvu yokuhlolaokuvumela ukugeleza ohlangothini olulodwa kuphela. Ivalvu yonyawo isetshenziswa lapho kudingeka khona iphampu, njengalapho amanzi edinga ukudonswa emthonjeni ongaphansi komhlaba. Ivalvu yonyawo igcina iphampu ivuliwe, ivumela amanzi ukuthi ageleze ngaphakathi kodwa ingawavumeli ukuthi ageleze emuva, okwenza ifaneleke ukusetshenziswa emachibini, emachibini nasemigodini.

Indlela i-valve yonyawo esebenza ngayo
Njengevalvu evumela ukugeleza kwendlela eyodwa kuphela, ivalvu yonyawo ivula indlela eyodwa bese ivala uma ukugeleza kuphambene. Lokhu kusho ukuthi ezisetshenziswayo ezifana nemithombo, amanzi angakhishwa kuphela emthonjeni. Noma imaphi amanzi asele epayipini awavunyelwe ukugeleza abuyele emuva ngevalvu aye emthonjeni. Ake sibheke le nqubo ngokuningiliziwe.

Emithonjeni yamanzi angaphansi komhlaba angajulile, ukusetshenziswa kwama-valve ezinyawo kuhilela okulandelayo:

Okokuqala, cabanga ngokuma kwevalvu yonyawo. Ifakwe ekugcineni kwepayipi (isiphetho emthonjeni lapho amanzi akhishwa khona). Itholakala eduze kwephansi lomthombo.
Uma ipompo isebenza, kudalwa ukumunca, kudonswe amanzi ngepayipi. Ngenxa yokucindezela kwamanzi angenayo, ivalvu engezansi iyavuleka lapho amanzi egeleza phezulu.
Uma ipompo icishiwe, ukucindezela okuphezulu kuyama. Uma lokhu kwenzeka, amandla adonsela phansi azosebenza emanzini asele epayipini, azame ukuwahambisa phansi abuyele emthonjeni. Kodwa-ke, ivalvu yonyawo iyakuvimbela lokhu ukuthi kwenzeke.
Isisindo samanzi epayipini sisunduzela phansi ivalvu engezansi. Ngenxa yokuthi ivalvu engezansi iyindlela eyodwa, ayivuli phansi. Esikhundleni salokho, ingcindezi evela emanzini ivala ivalvu ngokuqinile, ivimbele noma yikuphi ukubuyela emuva emgodini kanye nokusuka epompo kuya emfuleni.

Kungani udinga i-valve yonyawo?
Ama-valve ezinyawo ayasiza njengoba evimbela umonakalo ongaba khona ephampini ngenxa yokungaqhubeki kahle futhi ayeke ukuchitha amandla.

Lawa ma-valve ayingxenye ebalulekile yanoma yiluphi uhlelo lokupompa. Isibonelo esingenhla sichaza indlela i-valve yonyawo esebenza ngayo ngezinga elincane kakhulu. Cabanga ngomthelela wokungasebenzisiivalvu yonyawoezimweni ezinkulu nezinamandla aphezulu.

Uma kupompa amanzi kusuka epayipini lomhlabathi kuya ethangini eliphezu kwesakhiwo, kuyadingeka ukusebenzisa iphampu kagesi enamandla. Njengasezibonelweni, la maphampu ngokuvamile asebenza ngokudala ukumunca okuphoqa amanzi ukuthi akhuphuke ngepayipi aye ethangini elifunekayo.

Uma iphampu isebenza, kuba nekholomu yamanzi engaguquki ephayiphini ngenxa yokumunca okukhiqizwayo. Kodwa uma iphampu icishiwe, ukumunca kuyaphela futhi amandla adonsela phansi athinta ikholomu yamanzi. Uma ivalvu yonyawo ingafakwanga, amanzi azogeleza ephayiphini abuyele emthonjeni wawo wokuqala. Amaphayiphi azobe engenamanzi, kodwa agcwaliswe umoya.

Ngemuva kwalokho, uma ipompo ivulwa kabusha, umoya osepayipini uvimba ukugeleza kwamanzi, futhi noma ipompo ivuliwe, amanzi ngeke ageleze ngepayipini. Uma lokhu kwenzeka, kungabangela ukungasebenzi kahle futhi, uma kungaxazululwa ngokushesha, kungalimaza ipompo.

Ivalvu engezansi ixazulula ngempumelelo le nkinga. Uma iphampu icishiwe, ayivumeli noma yikuphi ukugeleza kwamanzi emuva. Iphampu ihlala ilungele ukusetshenziswa okulandelayo.

Inhloso yevalvu yonyawo
I-valve yonyawo iyi-valve yokuhlola esetshenziswa nephampu. Isetshenziswa ezimweni ezahlukahlukene ekhaya kanye nakwezinye izinhlelo zokusebenza zezimboni. Ama-valve onyawo angasetshenziswa namaphampu ampompa uketshezi (olubizwa ngokuthi amaphampu e-hydraulic) (njengamanzi) noma izinhlelo zokusebenza zezimboni (ezifana namagesi) (olubizwa ngokuthi amaphampu e-pneumatic).

Ekhaya, ama-valve onyawo asetshenziswa emachibini, emachibini, emithonjeni, nanoma yikuphi okunye okunepompo. Ezindaweni zezimboni, la ma-valve asetshenziswa kumaphampu endle, amaphampu okungenisa umoya asetshenziswa emifuleni nasemachibini, imigqa yamabhuleki omoya yamaloli ezentengiselwano, kanye nezinye izinhlelo zokusebenza lapho kusetshenziswa khona amaphampu. Asebenza kahle endaweni yezimboni njengoba enza echibini elingemuva kwendlu.

I-valve yonyawo yenzelwe ukugcina ipompo iqinile, ivumela uketshezi ukuthi lugeleze ngaphakathi, kodwa lungaphumi. Kunezihlungi ezimboza ukuvulwa kwe-valve futhi ezingavaleka ngemva kwesikhathi - ikakhulukazi uma zisetshenziselwa ukukhipha amanzi emthonjeni noma echibini. Ngakho-ke, kubalulekile ukuhlanza i-valve njalo ukuze iqhubeke isebenza kahle.

Khetha ivalvu yonyawo lwesokudla
i-valve yonyawo lwethusi oluseceleni

I-valve yonyawo iyadingeka ezimweni eziningi. Noma nini lapho kukhona uhlelo lokusebenza oludinga ukugeleza koketshezi okuqondile, i-valve yonyawo iyadingeka. I-valve yonyawo esezingeni eliphezulu isiza ukonga amandla futhi ivikele ipompo ekulimaleni, yandise isikhathi sayo sokuphila. Khumbula ukuthi kubalulekile ukusebenzisa i-valve yonyawo esezingeni eliphezulu ngangokunokwenzeka, njengoba kungaba nzima ukuyifinyelela uma isifakiwe.
