Li-valve tsa Ball ea Port e Felletseng khahlanong le tse Fokolitsoeng: Liphapang tsa Bohlokoa le Tataiso ea Khetho
Li-valve tsa bolo ke likarolo tsa bohlokoa litsamaisong tsa taolo ea mokelikeli, tse arotsoeng ka mefuta e 'meli e meholo: kou e felletseng (bore e felletseng) le kou e fokotsehileng (bore e fokotsehileng). Ho utloisisa liphapang tsa tsona ho netefatsa ts'ebetso e ntle le katleho ea litšenyehelo lits'ebetsong tsa indasteri.
Ho Hlalosa Li-Valve tsa Bolo ea Port e Felletseng khahlanong le tse Fokolitsoeng
-Belofo e Felletseng ea Bolo ea Port: Bophara ba kahare ba valve bo tsamaellana le ≥95% ea bophara bo tloaelehileng ba phaephe (mohlala, valve ea lisenthimithara tse 2 e na le tsela ea phallo ea 50mm).
Malebela: Ha o kgetha valve ya bolo, valve ya bolo ya 2 Inch e tletseng mokoti e na le boholo ba valve bo ngotsweng e le NPS 2.
- Valofo ea Bolo ea Kou e Fokolitsoeng: Bophara ba kahare ke ≤85% ea bophara bo tloaelehileng ba phaephe (mohlala, valve ea lisenthimithara tse 2 e na le tsela ea phallo ea ~38mm).
Keletso: Ha o kgetha valve ya bolo, valve ya bolo ya 2 Inch e fokoditsweng e na le boholo ba valve bo ngotsweng e le NPS 2 x 1-1/2.

Mokhoa oa ho Khetha Valve ea Ball e Nepahetseng
Beha Bore e Felletseng Pele Haeba:
1. Ho sebetsana le metswako e hlabang/e boreledi kapa ho hloka ho hlatsuwa.
2. Sistimi e hloka phallo e phahameng ka ho fetisisa ka tahlehelo e fokolang ea khatello.
3. Ho hlwekisa/ho hlokomela diphaephe ke ntho e tlwaelehileng.
Khetha Bore e Fokolitsoeng Ha:
1. Ho sebetsa ka likhase kapa maro a nang le viscosity e tlase.
2. Ho na le lithibelo tsa tekanyetso; li-valve tse bobebe lia khethoa.
3. Taolo ea phallo le ntlafatso ea sebaka ke tsa bohlokoa.
Lebaka Leo e Leng la Bohlokoa
1. Li-valve tse Felletseng tsa Bore li felisa lithibelo tsa phallo, li fokotsa litšenyehelo tsa matla lipalangoangng tsa maeto a malelele.
2. Li-valve tse Fokolitsoeng tsa Bore li fana ka phokotso ea litšenyehelo (ho fihlela ho 1/3 theko e tlase) le taolo e sebetsang ea phallo bakeng sa litsamaiso tse nyane, ha ka nako e ts'oanang li fokotsa moroalo oa sebopeho liphaepheng.
