Ku nghenelela eka matirhiselo, switirhisiwa leswikulu na swihlawulekisi swa xivumbeko xa valve yo kambela wafer

Ku kambela valve swivula valve leyi pfulaka hiku tisungulela naku pfala valve flap hiku titshega hi ku khuluka ka medium hi yoxe ku sivela ku tlhelela endzhaku ka medium, leyi tivekaka tani hivalve yo kambela, valve ya ndlela yin’we, valve ya ku khuluka ka le ndzhaku na valve ya ntshikelelo wa le ndzhaku. Ku...valve yo kambelai valve ya otomatiki leyi ntirho wa yona lowukulu ku nga ku sivela ku tlhelela endzhaku ka xitirhisiwa, ku rhendzeleka ka pompo na movha lowu chayelaka endzhaku, na ku humesiwa ka xitirhisiwa eka xigwitsirisi. Ti check valves tinga tlhela titirhisiwa eka ti layini leti phakelaka ti auxiliary systems laha ntshikelelo wunga tlakukaka ehenhla ka ntshikelelo wa system.

1.The ku tirhisa valve yo kambela wafer:

Ku...valve yo kambela yi vekiwile eka sisiteme ya tiphayiphi, naswona ntirho wa yona lowukulu i ku sivela ku tlhelela endzhaku ka xitirhisiwa. Ku...valve yo kambelai valve ya automatic leyi pfuriwaka no pfala kuya hi ntshikelelo wale xikarhi.Valve yo kambela wafer yi lulamerile eka ntshikelelo wa vito PN1.0MPa ~ 42.0MPa, Class150 ~ 25000; dyayimeta ya vito DN15 ~ 1200mm, NPS1 / 2 ~ 48; Ku khuluka ka le ndzhaku ka le xikarhi. Hiku hlawula switirhisiwa swohambana hambana, yinga cheriwa eka switirhisiwa swohambana hambana swofana na mati, steam, mafurha, nitric acid, acetic acid, strong oxidizing medium na uric acid.

2.The swilo leswikulu swavalve yo kambela wafer:

Kuna nsimbi ya khaboni, nsimbi ya mahiselo yale hansi, nsimbi ya swiphemu swimbirhi (F51/F55), titanium alloy, aluminium bronze, INCONEL, SS304, SS304L, SS316, SS316L, chrome molybdenum nsimbi, Monel (400/500), 20# alloy, Hastelloy na switirhisiwa swin’wana swa nsimbi.

3. Swihlawulekisi swa xivumbeko xavalve yo kambela wafer:

A. Ku leha ka xivumbeko i ko koma, naswona ku leha ka xivumbeko xa xona i 1/4~1/8 ntsena ya valve ya ndhavuko ya flange check

B. Vukulu byintsongo na ntiko wo vevuka, ntiko wa yona i ntsena 1/4 ~ 1/20 ya ndhavuko wa flange check valve

C. Disiki ya valve yi pfala hiku hatlisa naswona ntshikelelo wa hammer ya mati i wutsongo

D. Havumbirhi bya tiphayiphi leti nga horizontal kumbe tiphayiphi leti yimisiweke tinga tirhisiwa, swa olova ku ti veka

E. Flow channel yi rhetela naswona ku tiya ka fluid i kutsongo

F. Sensitive action na matirhelo ya kahle yo pfalela

G. Ku famba ka valve disc swi komile naswona matimba ya ku khumbeka yo pfala i matsongo

H. Xivumbeko hinkwaxo xa olovile naswona xi hlangana naswona xivumbeko xa xona xa saseka

I. Vutomi byo leha bya ntirho na matirhelo yo tshembheka

4.The swihoxo leswi tolovelekeke swa valve yo kambela hi leswi:

A. Disiki ya valve yi tshovekile

Ntshikelelo wa medium emahlweni na le ndzhaku ka check valve wu le ka xiyimo xa le kusuhi na balance na mutual “saw”. Disiki ya valve yitala ku biwa hi xitulu xa valve, naswona valve disc leyi endliweke hi swilo swin’wana leswinga brittle (kufana na cast iron, brass, na swin’wana) ya tshoveka. Ndlela yo sivela iku tirhisa check valve leyingana disc tani hi ductile material.

B. Ku khuluka ka le ndzhaku ka le xikarhi

Vuandlalo byo pfalela byi onhakile; thyaka ri pfaleriwile. Hiku lunghisa ndzhawu yo pfalela xikan’we naku basisa thyaka, ku tlhelela endzhaku swinga siveriwa.
