Hlawula nsinya wa ntirho wa valve, ku hlawuriwa na switsundzuxo swa ku veka

Ndlela leyi check valve yi tirhaka ha yona

Ku...valve yo kambela yi tirhisiwa eka sisiteme ya tiphayiphi, naswona ntirho wa yona lowukulu i ku sivela ku tlhelela endzhaku ka xitirhisiwa, ku rhendzeleka ka pompo na movha wa yona wo chayela, na ku humesiwa ka xitirhisiwa eka xigwitsirisi.

Ku kambela ti valve yinga tlhela yitirhisiwa eka tilayini leti phakelaka tisisiteme to pfuneta laha ntshikelelo wunga tlakukaka ehenhla ka ntshikelelo wa sisiteme leyikulu. Ti check valves tinga cheriwa eka tiphayiphi ta ti media to hambana hambana kuya hi switirhisiwa swohambana hambana.

Valve yo kambela yi vekiwa eka phayiphi naswona yi hundzuka xin’wana xa swiphemu swa mati swa phayiphi leyi heleleke. Endlelo ro pfula na ku pfala ra valve disc ri khumbeka hi xiyimo xa ku khuluka ka xinkarhana xa sisiteme leyi yi kumekaka eka yona; hi ku tlhelela, swihlawulekisi swo pfala swa disk ya valve i Yi na vuyelo eka xiyimo xa ku khuluka ka mati.

Languta ku hlawuriwa ka ti valve

1. Swing valve yo kambela

Disiki ya swing check valve yina xivumbeko xa disc naswona yi rhendzeleka eka shaft ya valve seat channel. Hikuva channel eka valve yi streamlined, flow resistance yitsongo kutlula ya lift check valve. Yi lulamerile eka ti flow rates tale hansi xikan’we naku cinca lokunga talaka eka ku khuluka. Hambiswiritano, ayi ringanelanga eka ku khuluka ka pulsating, naswona matirhelo ya yona yo pfalela aya kahle kufana na ya muxaka wa ku tlakusa.

Valve yo kambela swing yi avanyisiwile hi tinxaka tinharhu: muxaka wa single-lobe, muxaka wa double-lobe na muxaka wa multi-lobe. Swivumbeko leswi swinharhu ngopfu ngopfu swi avanyisiwile kuya hi diameter ya valve.

2. Tlakusa valve yo kambela

Valve yo kambela leyi eka yona disc ya valve yi rhetaka kuya hi layini yale xikarhi leyi yimisiweke ya miri wa valve. Valve yo kambela ku tlakusa yinga vekiwa ntsena eka phayiphi leyi nga horizontal, naswona bolo yinga tirhisiwa eka disc ya valve eka valve yo kambela ya ntshikelelo wale henhla ya diameter leyintsongo. Xivumbeko xa miri wa valve ya lift check valve xifana na xa globe valve (yinga tirhisiwa hiku fana na globe valve), hikokwalaho fluid resistance coefficient ya yona yikulu. Xivumbeko xa yona xifana na globe valve, naswona miri wa valve na disc swifana na globe valve.

3. Valve yo kambela phaphatani

Valve yo kambela leyi eka yona disc yi rhendzelekaka yi rhendzela pini leyi nga exitulwini. Valve yo kambela disc yina xivumbeko xo olova naswona yinga vekiwa ntsena eka phayiphi leyi nga horizontal, naswona matirhelo yo pfalela aya kahle.

4. Valava yo kambela tiphayiphi

Valve leyi eka yona disc yi rhetaka hi layini ya le xikarhi ya miri wa valve. Valve yo kambela tiphayiphi i valve leyintshwa. Yitsongo hi vukulu, yi vevuka hi ntiko naswona yikahle eka thekinoloji yo lulamisa. I yin’wana ya tindlela ta nhluvukiso wa check valve. Hambiswiritano, fluid resistance coefficient yikulu nyana kutlula ya swing check valve.

5. Valava yo kambela ntshikelelo

Muxaka lowu wa valve wutirhisiwa tani hi boiler feed water na steam cut-off valve, yina ntirho lowu hlanganisiweke wa lift check valve na globe valve kumbe angle valve.

Ku engetela kwalano, kuna ti check valve tin’wana letinga ringanelangiki eka ku vekiwa ka pump outlet, kufana na foot valve, muxaka wa spring, muxaka wa Y, na swin’wana.
