Ivalve ye-Civil edla ngokusetyenziswa ngoku yesiqhelo ivalve yesango losapho, ivalve yebhola, ivalve engunxantathu kunye nezinye iimo, ezenziwe ngokubanzi ngentsimbi okanye ubhedu.

Ngenxa iimpawu ezintle mechanical of ingxubevange yobhedu, kunye iingenelo akulula ukuba umhlwa, ukumelana umhlwa, ngoko ke iivalvu zobhedu ziye ngokuthe ngcembe endaweni ivalve yentsimbi.Umphezulu wevalve engunxantathu isetyenziswa ngokusisiseko kwi-electroplating, indima yayo ayikona nje ukulawula ukuhamba kwemithombo yeendaba, kodwa ikwadlala indima yokuhombisa.Ivalve engunxantathu idibanisa umbhobho kunye nombhobho wokungena kwamanzi kwimpompo yamanzi, isitya samanzi sendlu yangasese, sinawo umbhobho wokudibanisa kunye nombhobho wokungena kwamanzi ukwenzela unikezelo lwamanzi lwesifudumezi.

Iivalve zesango zisetyenziselwa ukudibanisa imibhobho kwiimitha zamanzi.

Iivalvu zebhola zisetyenziselwa ukudibanisa imibhobho kwizifudumezi zamanzi.

Ngenxa yokuba ivalve yebhola ivula kwaye ivale kunokuba ivalve yesango ikulungele, okwangoku umbhobho kunye noqhagamshelo lwemitha yamanzi lukwasebenzisa kakhulu ivalve yebhola.

UKhetho kunye noThengo lweeValufa zasekuhlaleni:

Iindidi ezahlukeneyo zeevalvu zoluntu kufuneka zikhethwe ngokweemfuno ezahlukeneyo zabasebenzisi:

1. Xa ukhetha kunye nokuthenga i-valve, akufanele kubekho umngxuma wesanti phezu komhlaba;umphezulu we-plating kufuneka ube ne-glossy kunye ne-uniform, kwaye ingqalelo kufuneka ihlawulwe ukuba ngaba kukho iziphene ezifana nokuxobula, ukuqhekeka, ukutshisa, ukukhupha, ukukhupha, indawo emnyama kunye neepockmarks ezicacileyo, njl. ezinye iziphene.Ezi ziphene zichaphazela ngqo ubomi benkonzo yevalve.

2. Umtya wombhobho wevalve udityaniswe nombhobho.Xa ukhetha kwaye uthenge, jonga ngokubonakalayo umphezulu wentambo kwiziphene ezicacileyo ezifana ne-dent, izinyo eliphukile, njl.Eyona nto ibaluleke kakhulu kukuba ubude obusebenzayo bentambo yombhobho kunye nesiqwenga sokudibanisa buya kuchaphazela ukuthembeka kokutywinwa ingqalelo ubude obusebenzayo bentambo yombhobho xa kuthengwa.Ubude obusebenzayo be-DN15 intambo yombhobho we-cylindrical malunga ne-10mm.

3. Ivalve yesango, ivalve yebhola ngokubanzi emzimbeni wayo okanye isiphatho esiphawulwe ngoxinzelelo lwegama, ukuthengwa kunokusekelwe kwiimfuno zabo.

4. Xa utshintsha isango elikhoyo okanye ivalve yebhola, qinisekisa ubude besakhiwo sevalve ukwenzela ukuba ingafakwa emva kokuthenga.

5. Kukho iindidi ezimbini zombhobho wevalve yevalve engunxantathu, intambo yangaphakathi kunye nentambo yangaphandle.Kufuneka sikhethe kwaye sithenge ngokweemfuno zethu.Kufuneka kwakhona sinikele ingqalelo kwivalve engunxantathu eyenziwe nge-alloy ye-zinc kwimarike ngoku.

Kufuneka uzame ukuthenga kwivenkile yezinto zokwakha eziqhelekileyo, ivenkile, ukwenzela ukuba umgangatho weemveliso uqiniseke ngakumbi.
