Indlela yokukhetha iValve yeStorm efanelekileyo yoLwandle

Ukukhetha inketho efanelekileyoivalvu yesiphephokuba inqanawa yakho ibalulekile ekugcineni ukhuseleko lwenqanawa kunye nokusebenza kwayo kakuhle, ingakumbi ekuthinteleni ukungena kwamanzi olwandle ngexesha lemozulu embi. Nazi izinto ezibalulekileyo ekufuneka uziqwalasele xa ukhetha ivalvu yesaqhwithi efanelekileyo.

1. Uhlobo lweValve kunye noCwangciso

Iivalvu zesiphepho ziza ngeentlobo ezahlukeneyo kunye noqwalaselo, nganye ifanelekile kwizicelo ezithile

• Ipateni Ethe Tye (Ethe Tye): Ilungele ukufakwa apho umbhobho usebenza ngokuthe nkqo.
• Iphethini ye-engile: Ifanelekile kwiipayipi ezitshintsha icala, ngesiqhelo kwi-engile ye-90-degree.

Khetha ubume obuhambelana noyilo lwemibhobho yenqanawa yakho ukuqinisekisa ukusebenza kakuhle.

2. Ubungakanani kunye neMigangatho yoQhagamshelo

Qinisekisa ukuba ubungakanani bevalvu buhambelana nobubanzi bombhobho wakho. Ubungakanani obuqhelekileyo buqala kwi-DN50 ukuya kwi-DN300. Ukongeza, qinisekisa ukuba uqhagamshelo lweflange yevalvu luyahambelana nemigangatho yenkqubo yakho, njengeeflange zePN16 okanye zeJIS-5K/JIS-10K.

3. Ukukhetha Izinto

Izinto ezisetyenziswayo mazikhethwe ngokusekelwe kwimeko yokusebenza

• Umzimba: Isinyithi esithambileyo okanye ubhedu ukuze simelane nokugqwala.
• Idiski kunye neStem: Ibronzi okanye intsimbi engatyiwayo ukumelana neemeko zaselwandle.
• Izitywino: I-NBR (iNitrile Butadiene Rubber) yokuvala nokuqina okusebenzayo.

Ukukhetha izixhobo ezifanelekileyo kuphucula ixesha elide kunye nokuthembeka kwevalvu.

4. Uvavanyo loxinzelelo kunye nobushushu

Qinisekisa ukuba umlinganiselo woxinzelelo kunye nobushushu bevalvu uyahambelana neemfuno zenkqubo yakho. Umzekelo, ezinye iivalvu zesiphepho zilinganiswa ngoxinzelelo oluphezulu lokusebenza oluyi-4 bar kunye nobushushu obuqala kwi--10°C ukuya kwi-60°C.

5. Indlela Yokuvala

Iivalvu zesiphepho zihlala zinendlela yokuvala ukuthintela ukubuya kwamanzi

• Ivili lesandla elenziwe ngesandla: Ivumela ukusebenza ngesandla ukuvula okanye ukuvala ivalvu njengoko kufuneka.
• Ukuvalwa Okuzenzekelayo: Ezinye iivalvu zenzelwe ukuvala ngokuzenzekelayo phantsi kweemeko ezithile.

Khetha indlela ehambelana neemfuno zakho zokusebenza kunye neenkqubo zokhuseleko.

6. Ukuthobela imithetho kunye nesiqinisekiso

Qinisekisa ukuba ivalvu yesiphepho iyahambelana nemigangatho kunye neziqinisekiso zoshishino lolwandle, njenge-DIN 87101 Form B okanye imibutho efanelekileyo yokwahlulahlula efana ne-Lloyd's Register okanye i-DNV. Ukuthobela imithetho kuqinisekisa ukuba ivalvu iyahlangabezana nemigangatho yokhuseleko kunye nomgangatho.

7. Ukugcinwa kunye noVavanyo

Khetha iivalvu ezilula ukuzigcina nokuzivavanya. Ukugcinwa rhoqo, kuquka novavanyo lwe-hydrostatic, kubalulekile ukuqinisekisa amandla evalvu kunye nokuxinana kwayo.
