Ilaphu lerabhaivalvu yokujonga amanziIkakhulu yenziwe ngomzimba wevalvu, isigqubuthelo sevalvu, iflaphu yerabha kunye nezinye izinto. Xa i-medium isiya phambili, uxinzelelo oluveliswa yi-medium lutyhala iflaphu yerabha ukuba ivuleke, ukuze i-medium ikwazi ukudlula kakuhle kwivalvu engabuyiyo kwaye ihambe iye kwicala ekujoliswe kulo. Xa i-medium inendlela yokuhamba ebuyela umva, uxinzelelo olubuyela umva lwe-medium luya kwenza iflaphu yerabha ivaleke ngokukhawuleza kwaye iqine kwisihlalo sevalvu, ngaloo ndlela ithintela i-medium kwi-countercurrent kwaye iqinisekise ukuba i-medium ekwipayipi ihamba kwicala elinye kuphela.

Ivalvu yokujonga i-flap yerabha ineenzuzo ezininzi kunevalvu zokujonga eziqhelekileyo:

1. Ukusebenza okuhle kokutywina

I-flap yerabha inokuguquguquka okuhle kunye nokuguquguquka, kwaye ingafakwa ngokusondeleyo kwisihlalo ukuthintela ngokufanelekileyo ukuvuza kwemidiya, kwaye isiphumo sokutywina singcono kune-valve yokujonga i-metal fitting.

2. Ukumelana namanzi okuphantsi

I-flap yerabha inokulandela kakuhle indlela amanzi ahamba ngayo xa ivuliwe, kwaye imo yayo kunye nezinto zayo zenza ukuba ukuxhathisa kwamanzi kuncinci, oku kunokunciphisa ukulahleka kwamandla kunye nokuphucula ukusebenza kakuhle kwenkqubo yemibhobho.

3. Isiphumo esihle sokuthulisa

Izinto zerabha zinamandla athile okufunxa uvalo kunye nokusebenza kokunciphisa ingxolo, kwaye zinokunciphisa imeko yokufunxa amanzi kunye nengxolo xa ivalvu yokujonga engabuyiyo ivaliwe, kwaye zidale imeko yokusebenza ezolileyo kwinkqubo.

4. Ukumelana nokugqwala

Irabha inokumelana kakuhle nokugqwala, iyakwazi ukuziqhelanisa neentlobo ngeentlobo zendalo, kulula ukuyigqwala yi-asidi kunye ne-alkali kunye nezinye izinto ezigqwalisayo, yandisa ubomi benkonzo yevalvu yokujonga isinyithi.

Iivalvu zokujonga irabha zihlala zisetyenziswa kwiinkqubo zokuhambisa amanzi kunye nemibhobho yamanzi, kwizikhululo zokucoca amdaka, kwizikhululo zokumpompa amanzi, kwiinkqubo zomlilo nakwezinye iindawo. Kwinkqubo yokuhambisa amanzi kunye nemibhobho yamanzi, ukuhamba kwamanzi kwakhona kunokuthintelwa ukuqinisekisa uzinzo kunye nokhuseleko lokunikezelwa kwamanzi. Kwisikhululo sokucoca amdaka, sinokuqinisekisa ukuba amanzi amdaka ahamba kwicala elichaziweyo kwinkqubo yokucoca, kwaye kuthintelwe ukuxutywa kwamanzi amdaka kwizigaba ezahlukeneyo zokucoca, nto leyo echaphazela isiphumo sonyango.

Kwisitishi sokumpompa, inokuthintela ngokufanelekileyo ukuhamba kwamanzi xa kucinywa, kwaye ikhusele ipompo nezinye izixhobo ekonakalisweni. Kwinkqubo yokulwa nomlilo, ukusebenza kwayo okuthembekileyo kokujonga kunokuqinisekisa ukuba amanzi omlilo anokunikezelwa kakuhle xa kufuneka ukuqinisekisa inkqubela phambili ethe tye yomsebenzi wokulwa nomlilo.
