Valve ea Bolo ea ho Weld ea Solvent ke eng?
A valve ea bolo ea weld ea solvente sebelisa bond ea fusion ea lik'hemik'hale ho e-na le ho tjheseletsa ka mocheso ho hokahanya likarolo tsa valve ka ho sa feleng le litsamaiso tsa liphaephe. Ho fapana le li-valve tsa setso tse tjheselitsoeng, ho tjheseletsa ka tharollo ho qhala likarolo tse ka holimo tsa thepa ea PVC/CPVC, ho etsa manonyeletso a sa lutleng ka ho tjheseletsa ka limolek'hule.
Likarolo tsa Sebopeho sa Motheo
– Kaho e sa dutleng: Ho kopanngoa ha lik'hemik'hale ho etsa hore ho be le dikgokelo tsa monolithic
– Ho hanyetsa mafome: E loketse bakeng sa mecha ea phatlalatso e mabifi (li-acid, li-solvents)
– Moralo oa tlhokomelo e se nang letho: Manonyeletso a sa feleng a felisa ho senyeha ha tiiso
– Ho kenya ho nyane: 40% e bobebe ho feta mekhoa e meng e nang le di-flange
– Phallo e tletseng: Ho fokotseha ho fokolang ha khatello liphaepheng
Litšebeliso tsa Bohlokoa
1. Ts'ebetso ea Lik'hemik'hale: HCl, H₂O₂, le mela ea phetisetso ea solvent
2. Phekolo ea Metsi: Mekhoa ea chlorine le li-unit tsa ho sefa
3. Meriana: Ho sebetsana le mokelikeli o lumellanang le USP Class VI
4. Tlhahiso ea Semiconductor: Kabo ea metsi a hloekileng haholo
Ho Wellisa ka Solvent khahlanong le ho Wellisa ka Setso
| Ntlha | Ho tjheseletsa Solvent | Ho tjheseletsa ka mocheso |
| Mokhoa oa Khokahano | Ho kopanngoa ha lik'hemik'hale | Ho qhibiliha ha tšepe |
| Ho lumellana ha thepa | PVC/CPVC feela | Tšepe le metsoako e kopantsoeng |
| Khanyetso ea Mocheso | 60°C (140°F) tekanyo e phahameng | 400°C+ (750°F+) |
| Bokhoni ba ho Kenya | Ho hlokahala koetliso e tlase | Ho hlokahala motjhini ea nang le setifikeiti |
NSW: Moetsi oa Valve ea Bolo ea Weld e Tšepahalang
E leSetifikeiti sa API 6Dmoetsi oa li-valve tsa bolo tse tjhitsitsoeng, NSW e fana ka:
–Mefuta e felletseng ea boholo: ½” ho isa ho 60″ di-valve tsa bolo ya weld ya solvent
–Litekanyetso tsa khatello: Sehlopha sa 150 ho isa ho Sehlopha sa 900
–Dikgetho tsa thepa: Meaho ea PVC, CPVC, PP, le PVDF
–Meralo e ikhethileng:
– Di-diverter tsa ditsela tse 3
– Mefuta e sireletsehileng mollong (API 607)
– Mehlala ea Cryogenic (-196°C)
– Li-actuator tsa ISO 5211 tse khahlanong le ho tsitsa
*Temoho ea Indasteri*: Li-valve tsa ho tjheseletsa tse qhibilihang li laola 78% ea litsamaiso tsa liphaephe tsa lik'hemik'hale tsa PVC tsa Amerika Leboea ka lebaka la litiiso tsa tsona tsa ho se hlahise metsi le bophelo ba tšebeletso ea lilemo tse 25 (tse lumellanang le ASME B31.3).
