Apho Ungayithenga khona iValve yeBhola: Isikhokelo sabaNiki abaPhambili beHlabathi

Yintoni iValve yeBhola

A ivalvu yebholayivalvu ejika ngekota esebenzisa ibhola engenanto, eneembobo, nejikelezayo ukulawula ukuhamba kolwelo. Xa umngxuma webhola uhambelana nombhobho, ulwelo luyadlula; ukujikeleza ibhola ngama-90 degrees kuvala ukuhamba kwayo ngokupheleleyo. Yaziwa ngokuqina kwayo, ukusebenza kwayo ngokukhawuleza, kunye nokuvala ngokuqinileyo, iivalvu zebhola zisetyenziswa kakhulu kwiinkqubo zoshishino, zorhwebo, kunye nezokuhlala kwiindawo zolwelo, iigesi, kunye ne-slurry.

Iindidi eziqhelekileyo ziqukaIivalvu ezi-3 zendlela ezi-1 nezi-2(ukuze kuphambukiswe ukuhamba kwamanzi) kunyeIvalvu yebhola eyi-1 1 2(ilungele imibhobho ephakathi).

Indlela yokukhetha iValve yeBhola

1. Ngokobungakanani

Tshatisa ubungakanani bevalvu nobubanzi bombhobho wakho. Ubungakanani obuqhelekileyo buquka:

–Ivalvu yebhola eyi-1 1 2: Ilungele iipayipi eziyi-1.5 intshi.

–Iivalvu ezi-3 zendlela ezi-1 nezi-2: Isetyenziselwa ukuthuthwa kwamasebe kwiinkqubo ezincinci.

2. Ngoxinzelelo

Jonga umlinganiselo woxinzelelo lwevalvu (PSI/bar). Iinkqubo zoxinzelelo oluphezulu zifuna iivalvu zentsimbi ezenziwe ngobumba.

3. Ngokwezinto eziphathekayo

–Yenziwe ngentsimbi eshayinayo: Ayikwazi ukumelana nokugqwala kwiindawo ezinobungozi (jongaI-10 Stainless Ball Valve ephezulu).

–Intsimbi yobhedu: Ifikeleleka lula ngamanzi negesi.

–I-PVC: Ilula xa isetyenziswa ngamakhemikhali.

4. NguMkhiqizo

Khetha iimpawu ezithembekileyo ezifana ne-Emerson Valves (yehlabathi) okanyeUmvelisi weValve ye-NSW(eTshayina) ukuqinisekisa umgangatho.
