BS5163 E Resilient e Lutseng Setho se sa Phahameng Se Lahleleng Valofo ea Heke ea tšepe
TLHOKOMELO MOKHOPO
● Moralo le Tlhahiso e Lumellana le BS5163
● Maemo a Flange a Lumellana le EN1092-2 PN10,PN16,PN25
● Litekanyo tsa Sefahleho le Sefahleho li Lumellana le BS5163
● Testing Conform to BS5163、EN12266-1
● Mokhoa oa ho khanna: lebili la letsoho, sekoahelo sa lisekoere
Ho kenya le ho hlokomela valve ea heke ho tla ela hloko lintlha tse latelang:
Lebili la letsoho, mofeng le mochine oa phetiso ha lia lumelloa ho sebelisoa bakeng sa ho phahamisa, 'me ho thulana ho thibetsoe ka thata.
Li-valve tsa liheke tse peli li tla kengoa ho ea holimo (ke hore, kutu e eme e otlolohileng 'me lebili la letsoho le ka holimo).
Sephahla sa heke se nang le valve ea bypass se tla bula valve ea bypass pele e buloa (ho leka-lekanya phapang ea khatello sebakeng sa ho kena le ho tsoa le ho fokotsa matla a ho bula).
Valve ea heke e nang le mochini oa phetisetso e tla kenngoa ho latela lipehelo tsa bukana ea ts'ebetso ea sehlahisoa.
Haeba valve e atisa ho buloa le ho koaloa, e tlotse bonyane hang ka khoeli.
Ho ea ka mokhoa oa ho khanna oa valve, e arotsoe ka valve ea heke ea motlakase, valve ea heke ea pneumatic le valve ea heke ea manual.
