Iivalvu zokuhlola, ezaziwa ngokuba ziivalvu ezingabuyisiyo (ii-NRV), ziyinxalenye ebalulekileyo yayo nayiphi na inkqubo yemibhobho yemizi-mveliso okanye yezindlu. Zisetyenziselwa ukuthintela ukubuya kwamanzi, ukuqinisekisa ukusebenza kakuhle kwenkqubo kunye nokuthintela umonakalo.

Iivalvu zokujonga zisebenza ngokulula. Uxinzelelo oludalwa lulwelo oluhamba kwinkqubo yepayipi luvula ivalvu, kwaye naluphi na ujikelezo olubuyela umva luvala ivalvu. Ivumela ulwelo ukuba luhambe ngaphandle kokuthintelwa kwicala elinye kwaye luzivale ngokuzenzekelayo xa uxinzelelo lunciphile. Nangona oku kulula, kukho iintlobo ezahlukeneyo zeevalvu zokujonga ezinemisebenzi eyahlukeneyo kunye nezicelo. Uyazi njani ukuba loluphi uhlobo lwevalvu yokujonga omawuyisebenzise emsebenzini okanye kwiprojekthi yakho? Ukukunceda wenze ukhetho olufanelekileyo, nazi ezinye iinkcukacha ngeentlobo eziqhelekileyo zeevalvu zokujonga.

Ivalvu yokujonga iswing
I-White PVC Swing CheckSwing Check Valve isebenzisa idiski ngaphakathi kwivalvu ukuvumela okanye ukumisa ukuhamba kwenkqubo yemibhobho. Xa ulwelo luhamba kwicala elifanelekileyo, uxinzelelo lunyanzela idiski ukuba ivuleke kwaye ihlale ivulekile. Njengoko uxinzelelo luncipha, idiski yevalvu iyavalwa, ithintele ukuhamba kwakhona kolwelo. Iivalvu ze-Swing check ziyafumaneka kwiintlobo ngeentlobo zezinto, kubandakanya i-PVC, i-CPVC, i-clear, kunye ne-industrial.

Kukho iintlobo ezimbini zeevalvu zokujonga i-swing ekufuneka sigxile kuzo:

• I-Top Hinged – Kule valve yokujonga ukujika, idiski incamathiselwe kumphezulu ongaphakathi wevalvu nge-hinge evumela idiski ukuba ivuleke kwaye ivale.

• I-Swashplate – Le valve yokujonga ukujika yenzelwe ngendlela evumela ivalvu ukuba ivuleke ngokupheleleyo kwaye ivale ngokukhawuleza xa uxinzelelo lokuhamba kwamanzi luphantsi. Ikwenza oku isebenzisa idiski enomfanekiso wedome enentwasahlobo ukuvumela ivalvu ukuba ivale ngokukhawuleza kunevalvu ene-hinged ephezulu. Ukongeza, idiski ekule valve yokujonga iyadada, ngoko ke ulwelo luhamba phezulu nasezantsi komphezulu wediski.
Olu hlobo lweevalvu zokujonga lusetyenziswa kakhulu ukuthintela ukukhukula kwiinkqubo zamanzi amdaka kunye nezicelo zokukhusela umlilo. Zisetyenziswa kwiinkqubo ezihambisa ulwelo, iigesi kunye nezinye iintlobo zemidiya.

Nyusaivalvu yokujonga
Iivalvu zokujonga ilifti zifana kakhulu neevalvu zeglobe. Zisebenzisa iipiston okanye iibhola endaweni yeediski ezisetyenziswa ziivalvu zokujonga ezijikelezayo. Iivalvu zokujonga ilifti zisebenza ngcono ekuthinteleni ukuvuza kuneevalvu zokujonga ezijikelezayo. Makhe sijonge ezi valve zimbini zokujonga ilifti:

• Ipiston – Olu hlobo lwevalvu yokujonga ikwabizwa ngokuba yivalvu yokujonga iplagi. Ilawula ukuhamba kolwelo kwiinkqubo zemibhobho ngokuhamba okuthe ngqo kwepiston ngaphakathi kwigumbi levalvu. Ngamanye amaxesha ipiston inesipilingi esiqhotyoshelweyo, esinceda ukuba ihlale ivaliwe xa ingasetyenziswa.

Ivalvu yeBhola yokujonga iBhola yePVC ecacileyo • Ivalvu yeBhola – Ivalvu yokujonga iBhola isebenza ngokulula ngokusebenzisa amandla angaphantsi komhlaba. Xa kukho uxinzelelo olwaneleyo kulwelo, ibhola iyaphakanyiswa, kwaye xa uxinzelelo lunciphile, ibhola iyaqengqeleka ize ivale ukuvulwa. Iivalvu zokujonga iBhola ziyafumaneka kwiintlobo ngeentlobo zezinto kunye neentlobo zesitayile: I-PVC: ecacileyo nengwevu, i-CPVC: edibeneyo yokwenyani kunye nencinci.

Nyusaiivalvu zokujongaZisetyenziswa kwiindawo ezininzi zokusebenza kumashishini amaninzi. Uza kuzifumana kwiindawo zokuhlala nakwiindawo zoshishino. Zisetyenziswa kumashishini okutya neziselo, kumashishini eoyile negesi, nakwishishini lezolwandle, ukubala ezimbalwa.

Ivalvu yokujonga ibhabhathane
Ivalvu yokujonga ibhabhathane ikhethekile kuba idiski yayo igoba embindini ukuze kuvunyelwe ulwelo ukuba luhambe. Xa ukuhamba kujika, la macala mabini avuleka kwakhona ukuze kutywinwe ivalvu evaliweyo. Le valve yokujonga, eyaziwa ngokuba yivalvu yokujonga ipleyiti ephindwe kabini okanye ivalvu yokujonga idiski egoqekayo, ifanelekile kwiinkqubo zolwelo oluphantsi koxinzelelo kunye neenkqubo zepayipi yegesi.

Ivalvu yokujonga iglobe
Iivalvu zokujonga ezivaliweyo zikuvumela ukuba uqale kwaye uyeke ukuhamba kwenkqubo yemibhobho. Zahlukile kuba zikuvumela ukuba ulawule ithrafikhi. Ivalvu yokujonga iglobe ngokusisiseko yivalvu yokujonga enolawulo lokugqitha olumisa ukuhamba nokuba kuhamba ngayiphi na indlela okanye uxinzelelo. Xa uxinzelelo luphantsi kakhulu, ivalvu yokujonga ivala ngokuzenzekelayo ukuthintela ukuhamba kwakhona. Olu hlobo lwevalvu yokujonga lungasebenza ngokusebenzisa ulawulo lwangaphandle endaweni yolawulo lokugqitha, oko kuthetha ukuba ungayiseta ivalvu kwindawo evaliweyo nokuba kuhamba ngayiphi na indlela.

Iivalvu zokujonga iglobe zisetyenziswa kakhulu kwiinkqubo zebhoyila, kwizikhululo zamandla, kwimveliso yeoyile nakwizicelo zokhuseleko oluphezulu.

Iingcinga Zokugqibela malunga neeValve zokujonga
Xa kufikwa ekuthinteleni ukubuya kwamanzi, akukho ndlela ngaphandle kwevalvu yokujonga. Ngoku ekubeni usazi kancinci ngeentlobo ezahlukeneyo zeevalvu zokujonga, kuya kufuneka ukwazi ukugqiba ukuba yeyiphi efanelekileyo kwisicelo sakho.
