Indlela Yokukhetha I-Storm Valve Efanele Ye-Marine

Ukukhetha okufaneleivalvu yesiphephongoba umkhumbi wakho ubalulekile ekugcineni ukuphepha nokusebenza kahle komkhumbi, ikakhulukazi ekuvimbeleni ukungena kwamanzi olwandle ngesikhathi sezulu esibi. Nazi izinto ezibalulekile okufanele uzicabangele lapho ukhetha ivalvu yesiphepho efanele

1. Uhlobo lwe-Valve kanye nokucushwa

Ama-valve esiphepho afika ngezinhlobo ezahlukene kanye nokucushwa, ngalinye lifanele izinhlelo zokusebenza ezithile

• Iphethini Eqondile (Eqondile): Kulungele ukufakwa lapho ipayipi lihamba khona liqonde phezulu.
• Iphethini ye-engela: Kufanelekela amapayipi ashintsha indlela, ngokuvamile nge-engeli engama-degree angu-90.

Khetha ukucushwa okuhambisana nokwakheka kwamapayipi omkhumbi wakho ukuqinisekisa ukusebenza kahle kakhulu.

2. Usayizi kanye nezindinganiso zokuxhuma

Qinisekisa ukuthi usayizi we-valve ufana nobubanzi bombhobho wakho. Osayizi abavamile basukela ku-DN50 kuya ku-DN300. Ngaphezu kwalokho, qinisekisa ukuthi ukuxhumana kwe-flange ye-valve kuyahambisana nezindinganiso zesistimu yakho, njenge-PN16 noma i-JIS-5K/JIS-10K flanges.

3. Ukukhethwa Kwezinto Ezibalulekile

Izinto zokwakha kufanele zikhethwe ngokusekelwe endaweni yokusebenza

• Umzimba: Insimbi ethambile noma ithusi yokumelana nokugqwala.
• Idiski kanye nesiqu: Ithusi noma insimbi engagqwali ukumelana nezimo zasolwandle.
• Izimbonakaliso: I-NBR (i-Nitrile Butadiene Rubber) yokuvala nokuqina okuphumelelayo.

Ukukhetha izinto ezifanele kuthuthukisa isikhathi eside kanye nokuthembeka kwevalvu.

4. Izilinganiso Zokucindezela Nokushisa

Qinisekisa ukuthi izilinganiso zokucindezela kanye nokushisa kwevalvu ziyahambisana nezidingo zesistimu yakho. Isibonelo, amanye amavalvu esiphepho alinganiswa ngokucindezela okuphezulu kokusebenza okungu-4 bar kanye namazinga okushisa asukela ku--10°C kuya ku-60°C.

5. Indlela Yokuvala

Ama-valve esiphepho ngokuvamile anendlela yokuvala ukuvimbela ukugeleza kwamanzi emuva

• Isondo Lesandla Eliphathwayo: Ivumela ukusebenza ngesandla ukuvula noma ukuvala ivalvu njengoba kudingeka.
• Ukuvalwa Okuzenzakalelayo: Amanye ama-valve aklanyelwe ukuvala ngokuzenzakalelayo ngaphansi kwezimo ezithile.

Khetha indlela efanelana nezintandokazi zakho zokusebenza kanye nezinqubo zokuphepha.

6. Ukuthobela imithetho kanye nesitifiketi

Qinisekisa ukuthi ivalvu yesiphepho ihambisana nezindinganiso kanye nezitifiketi zemboni yasolwandle, njenge-DIN 87101 Form B noma izinhlangano ezifanele zokuhlela njenge-Lloyd's Register noma i-DNV. Ukuthobela imithetho kuqinisekisa ukuthi ivalvu ihlangabezana nezindinganiso zokuphepha kanye nekhwalithi.

7. Ukugcinwa Nokuhlolwa

Khetha ama-valve okulula ukuwanakekela nokuwahlola. Ukulungiswa njalo, okuhlanganisa nokuhlolwa kwe-hydrostatic, kubalulekile ukuqinisekisa amandla e-valve kanye nokuqina kwayo.
