Ngaba ivalve yokukhangela kufuneka ifakwe phambi okanye emva kwevalve yokuphuma?

Kwiinkqubo zemibhobho, ukukhethwa kunye nokufakwa kwendawo yeevalvu kubalulekile ekuqinisekiseni ukuhamba kakuhle kwamanzi kunye nokhuseleko lwenkqubo. Eli nqaku liza kuphonononga ukuba ngabakhangela iivalvekufuneka zifakwe phambi okanye emva kweevalvu zokuphuma, kwaye nixoxeiivalve zesangokwayeIzihluzi ze-Y.

Okokuqala, kufuneka siqonde umsebenzi we-akhangela ivalve. Ivalve yokutshekisha yivalve yendlela enye esetyenziselwa ukuthintela ukubuya umva. Xa ulwelo luhamba ngevalve yokutshekisha, i-disc iyavula, ivumela ulwelo ukuba luhambe. Xa i-fluid igeleza kwicala elichaseneyo, i-disc ivala, ikhusela umva. Olu phawu lwenza ukuba iivalvu zetshekhi zibaluleke kakhulu kwiinkqubo ezininzi zemibhobho, ngakumbi ukuthintela ukubuya umva kwiimpompo kunye nezixhobo zokukhusela.

Xa uqwalasela indawo yokufaka ikhangela ivalve, kukho iinketho ezimbini ngokubanzi: ngaphambi okanye emva kwevalve yokuphuma. Inzuzo ephambili yokufaka i-valve yokujonga phambi kokuba i-valve yokuphuma kukuba ikhusela ngokufanelekileyo ukubuyisela umva, ukukhusela izixhobo ezisezantsi kumonakalo. Olu lungelelwaniso lubaluleke kakhulu kwiinkqubo ezifuna ukuhamba ngokulinganayo. Ngokomzekelo, ukufakela i-valve yokujonga kwindawo yokuphuma kwempompo kuthintela umva emva kokuba umpompo umisiwe, unokuba yingozi kwimpompo.

Ngakolunye uhlangothi, ukufaka i-valve yokukhangela emva kwevalve yokuphuma nayo ineenzuzo zayo ezizodwa. Kwezinye iimeko, ivalve yokuphuma ingafuna ukulungiswa okanye ukutshintshwa. Ukufaka i-valve yokukhangela emva kokuba i-valve yokuphuma ivumela ukufikelela lula ngaphandle kokuphazamisa ukusebenza kwenkqubo yonke. Ngaphaya koko, kwiinkqubo zemibhobho entsonkothileyo, ukutshintsha phakathi kweendlela ezahlukeneyo zolwelo kungafuneka. Ukufaka i-valve yokukhangela emva kwevalve yokuphuma inika ukuguquguquka okukhulu.

Ukongeza kwi-valve yokukhangela,iivalve zesangokwayeY-izihluzizikwayinto eqhelekileyo kwiinkqubo zombhobho. Iivalve zesango zisetyenziselwa ukulawula ukuhamba kwamanzi kwaye zisetyenziswa ngokuqhelekileyo kwizicelo apho indlela yokuhamba kufuneka ivulwe ngokupheleleyo okanye ivalwe. Ngokungafaniyo neevalve zokujonga, iivalve zesango azikuthinteli ukubuyela ngasemva. Ke ngoko, xa uyila isixokelelwano semibhobho, kubalulekile ukuqwalasela ngokuchanekileyo ezi ntlobo zimbini zevalvu ukuqinisekisa ukusebenza ngokukhuselekileyo nangokusebenzayo.

I-Y-type strainers isetyenziselwa ukucoca ukungcola kumanzi, ukukhusela ukusebenza okuqhelekileyo kwezixhobo ezisezantsi. Xa ufaka i-aIsihluzi se-Y, ngokuqhelekileyo kucetyiswa ukuba uyifake phambi kokuba i-valve yokutshekisha ukuqinisekisa ukuba i-fluid ehluziweyo inokuhamba kakuhle kwizixhobo ezisezantsi. Oku kuthintela ngokufanelekileyo ukungcola kwizixhobo ezonakalisayo kunye nokuphucula ukuthembeka kwenkqubo.

Isishwankathelo, indawo yokufakela i-valve yokutshekisha kufuneka imiselwe ngokusekelwe kwiimfuno ezithile zenkqubo yokubhobhoza. Ingaba ifakwe ngaphambi okanye emva kwevalve yokuphuma, iimpawu zolwelo lwenkqubo, iimfuno zokukhusela izixhobo, kunye nokulula kokugcinwa kufuneka kuqwalaselwe ngokubanzi. Ngaphezu koko, ukucwangciswa okufanelekileyo kweevalve zesango kunyeIzihluzi ze-Yiya kuphucula ukusebenza kakuhle kunye nokhuseleko lwenkqubo yonke yemibhobho. Xa uyila kwaye ufaka inkqubo yokubhobhoza, kuyacetyiswa ukuba udibane neengcali ukuqinisekisa ukucwangciswa kwevalve efanelekileyo.
