Intsimbi yebholaivalvu yokujonga amanziluhlobo lwevalvu esetyenziswa kwiinkqubo zemibhobho, umsebenzi wayo ophambili kukuthintela ukuba i-medium ingabuyeli emva kwipayipi, ngelixa ikhusela ipompo kunye nenkqubo yemibhobho kumonakalo obangelwa yihammer yamanzi. Izinto zentsimbi ezithambileyo zinika amandla agqwesileyo kunye nokumelana nokugqwala, okwenza ukuba ifaneleke kwiimeko ezahlukeneyo zokusebenza.

Umgaqo wokusebenza wevalvu yentsimbi ethambileyo engabuyiyo usekelwe kumahluko woxinzelelo oluveliswa kukuhamba kwesixhobo. Xa isixhobo sihamba phambili, ivalvu iyavuleka, ivumela ulwelo ukuba ludlule. Xa isixhobo sizama ukuhamba ngasemva, ibhola engaphakathi kwevalvu ityhalelwa kwisihlalo sevalvu phantsi koxinzelelo lwesixhobo, ngaloo ndlela ivala ivalvu kwaye ithintele isixhobo ukuba singabuyeli umva. Olu yilo luqinisekisa ukusebenza ngokuzenzekelayo kwevalvu ngaphandle kwesidingo somthombo wamandla wangaphandle.

Iingenelo zevalvu yokujonga i-ductile iron non return ziquka:

1. Ulwakhiwo oluncinci: Xa kuthelekiswa neevalvu zokujonga zemveli, iivalvu zokujonga isinyithi esithambileyo zinobude obufutshane bolwakhiwo, umthamo omncinci, ubunzima obuphantsi, kwaye kulula ukuzifaka nokuzilungisa.

2. Ukusebenza kakuhle kokutywina: ukusebenzisa iiflephu zebhola ye-foreskin yerabha ukubonelela ngesiphumo esihle sokutywina nokunciphisa ukuvuza.

3. Ukuthulisa: Xa icinyiwe, inokunciphisa amaza ehammer yamanzi, yehlise ingxolo, kwaye ikhusele inkqubo yemibhobho.

4. Ukumelana nokuguguleka: Umaleko oncamathelayo wesphere unokuqina okuhle kunye nokumelana nokuguguleka, nto leyo eyandisa ubomi benkonzo yevalvu.

5. Isebenza kakuhle: Ingasetyenziselwa izinto ezahlukeneyo ezifana namanzi abandayo, amanzi ashushu, amanzi amdaka emizi-mveliso nasekhaya, kwaye ifanelekile ukufakwa ngokuthe tye okanye ngokuthe nkqo.

6. Ukunciphisa isiphumo sehammer yamanzi: Uyilo lokuvala ngokukhawuleza lunceda ekunciphiseni ukwenzeka kwehammer yamanzi kunye nokukhusela inkqubo yemibhobho.

7. Ukulungiswa okulula: iindawo ezimbalwa, kulula ukuziqhaqha, kunye neendleko zokulungisa ezincitshisiweyo.

Ngenxa yobushushu obuphezulu, uxinzelelo oluphezulu, kunye nendawo egqwalisayo, ivalvu yokujonga isinyithi esithambileyo i-8 intshi isetyenziswa kakhulu kwishishini le-petrochemical ukuthintela ukubuya kwamanzi okuphakathi kunye nokuqinisekisa ukhuseleko kunye nokuzinza kwenkqubo yemveliso. Kwinkqubo yokungena kunye nenkqubo yamanzi okutya ye-turbine yomphunga, iivalvu zokujonga isinyithi esithambileyo zinokuthintela ukuhamba okungasemva komphunga kunye namanzi okutya, zikhusela ukusebenza okuqhelekileyo kweyunithi. Amanye amashishini aquka iinkqubo zokubonelela ngamanzi kunye nemibhobho kamasipala, amashishini eekhemikhali kunye namayeza, ngakumbi kwishishini lokucoca amanzi okusingqongileyo. Kwiinkqubo zokucoca amanzi, iivalvu zokujonga isinyithi esithambileyo zinokuthintela ngokufanelekileyo amanzi amdaka ukuba abuye kwaye ziqinisekise ukhuseleko lomgangatho wamanzi.
