Ngokubanzi, kuyacetyiswa ukuba ivelve yamanzi itshintshwe rhoqo kwiminyaka emi-5 ukuya kwengama-10.

Okokuqala, indima yamanzi evali

Ivalve yamanzi yinxalenye ebalulekileyo yenkqubo yepayipi, eyona ndima kukulawula ukuhamba kwamanzi kumbhobho, kwaye ukuba kukho imfuneko, ukuvula ukuhamba kwamanzi.
Iivalve zamanzi zihlala zibandakanya i-plug, ivali yebhola, i-valve yebhabhathane kunye nezinye iintlobo, ezi valve zahlukile kwizixhobo, izakhiwo zahlukile kwizinto, kodwa ziyafana.

Okwesibini, ubomi bevalthi yamanzi
Ubomi bevaluni yamanzi buxhomekeke kwinani lezinto, kubandakanya nezinto, umgangatho, ukusetyenziswa rhoqo, njalo njalo. Phantsi kweemeko eziqhelekileyo, ivalve esemgangathweni esemgangathweni inokusetyenziselwa iminyaka engama-20, ngelixa iivalda ezisemgangathweni zinokusetyenziswa kuphela iminyaka embalwa.

Ezintathu, umjikelo wokutshintshwa kwe-valve
Kuba i-valve yamanzi ivezwa kukuhamba kwamanzi ixesha elide, zichaphazeleka kukungasebenzi, zinxibe kunye nokwaluphala. Ke ngoko, ukuqinisekisa ukusebenza okuqhelekileyo kwenkqubo yombhobho, kuyacetyiswa ukujonga imeko yevalve yamanzi kwaye ithathe indawo ngokweyona meko.
Ngokubanzi, kuyacetyiswa ukuba ivelve yamanzi itshintshwe rhoqo kwiminyaka emi-5 ukuya kwengama-10. Ukuba zihlala zisetyenziswa kwi-hards ezihamba kakhulu kunye nemeko yoxinzelelo oluphezulu, umjikelo wokutshintshwa unokuba mfutshane.

Ulondolozo lweVenkile
Phambi kokuba kutshintshwe i-velove ye-valve yamanzi, ukugcinwa rhoqo kunye nokugcinwa kwayo kuyimfuneko. Ngokubanzi, unokwenza la manyathelo alandelayo:
1. Hlambulula i-valve kunye nendawo ejikelezileyo ye-dill kunye ne-sediment.
I-2. Inyibilikisile ivalve eneoyile yokuthambisa okanye igrisi yokunciphisa ukunxiba.
3. Jonga ukuba i-valve ine-rocks, iskisformation kwaye inxibe iingxaki, kwaye ithathe indawo yayo ngexesha ukuba inyanzelekile.

Isishwankathelo

I-Valvers yamanzi licandelo elibalulekileyo kwinkqubo yokulinganisa, kunye nokuqinisekisa ukusebenza kwazo kunye nokhuseleko, kuyacetyiswa ukuba kuhlolwe rhoqo, kutshintsha indawo kwaye ugcine ivalve. Phantsi kweemeko eziqhelekileyo, kucetyiswa ukuba kuthathelwe indawo yonke iminyaka emi-5 ukuya kweli-10, kwaye ubomi benkonzo bayo bunokwandiswa ngamanyathelo okugcina.
