Lug vs. Wafer Butterfly Valves: Ku hambana ka nkoka & Nkongomiso

Tivalvu ta phaphataniva hoxa xandla swinene eku lawuleni ka ku khuluka ka swilo swo hambana-hambana leswi nga ni mati ni tigasi. Exikarhi ka tinxaka tohambana hambana ta ti valve ta maphaphatani, ti valve ta lug butterfly na waferti valve ta phaphatanii swihlawulekisi swimbirhi leswi tirhisiwaka ngopfu. Tinxaka leti hatimbirhi ta ti valve tina mintirho yo hlawuleka naswona ti lulamerile eka switirhisiwa swokarhi.TWSyi ta kambisisa ku fana ka tona ni ku hambana ka tona eka xihloko lexi, hi ntshembo wa leswaku yi ta ku pfuna ku endla swiboho leswi nga ni vutivi loko u hlawula valve leyi faneleke.

I. Ku fana exikarhi ka vona.

1. Ku tirhaPrinciple.

Havumbirhi bya ti wafer type butterfly valves na lug type butterfly valves ti lawula ku khuluka ka medium hiku rhendzeleka ka valve disc. Angle yo rhendzeleka ya valve disc yingava ntsena exikarhi ka 0 kuya eka 90 degrees, sweswo swivula leswaku, valve yi pfulekile hiku hetiseka eka 90 degrees naswona yi pfariwile hiku hetiseka eka 0 degrees. Lowu i nsinya wa nawu lowu tirhaka wa ti valve ta maphaphatani.

2. Swi fanaKu langutana na xikandza

Valve ya wafer butterfly na lug butterfly valve swi endliwile tani hi muxaka wo olova, leswi tekaka ndzhawu yitsongo naswona swi lulamerile ku vekiwa eka sisiteme ya tiphayiphi leyingana ndzhawu leyintsongo.

3. Dizayini leyi ringaniseriweke:

Havumbirhi bya tona ti landzelela swipimelo swa matiko ya misava swa ti indasitiri, swa olova ku hlanganisa na ti flanges ta ntolovelo, naswona tinga cinciwa hiku olova eka tisisiteme letinga kona.

II.Yini's ku hambana ka kona?

Havumbirhi bya ti wafer type butterfly valves na lug type butterfly valves swivula xivumbeko xa vuhlanganisi bya ti butterfly valves, letingana ku leha ka xivumbeko lexi fanaka na swikongomelo leswi fanaka, kambe kuna ku hambana lokukulu eka dizayini, ku vekiwa, ku tirhisiwa, ntsengo, na swin’wana.

1. 1. .VukhavisiDswihlawulekisi

Lug butterfly valve: Makumu hamambirhi ya miri wa valve ya endliwe hi ti threaded lugs, leti pfunaka swinene ku lulamisa valve.

Wafer butterfly valve: Kuhambana na sweswo, ayi na ti threaded inserts, kambe yi clamped exikarhi ka ti flanges timbirhi, na ti bolts leti hundzaka eka pipeline flange na valve body kuva yi lulamisa. Hi leswaku, yi endliwe hi ntshikelelo wa tiboloti leti tsindziyelaka flange ya phayiphi.

2. 2. .Ku vekiwa ka swiloProcess.

• Lugvalve ya phaphatani: .

Ti valve ta lug butterfly ti lulamerile eka tiphayiphi leti lavaka ku hlayisiwa nkarhi na nkarhi kumbe ku tshamela ku hambanisiwa. Ti threaded inserts ta olova ku ti veka naku ti hambanyisa handle ko onha sisiteme hinkwayo ya tiphayiphi. Valve ya phaphatani leyi humelaka ehandle yinga vekiwa emakumu ka phayiphi naswona yitirhisiwa tani hi valve ya makumu.

- Tiyisisa leswaku ti lugs ti ringanisiwile kahle na ti flange bolts ku papalata ntshikelelo eka miri wa valve.

- Tirhisa switirhisiwa swa gasket leswi faneleke loko swilaveka ku sivela ku vupfa, ngopfu ngopfu eka tisisiteme ta ntshikelelo wa le xikarhi.

- Tiyisisa ti boluti hiku ringana ku hlayisa ntshikelelo lowu fanaka endzeni ka valve.

• Wafervalve ya phaphatani: .

Ti wafer butterfly valves ti lulamerile swinene ku hlanganisa makumu hamambirhi ya tiphayiphi eka swiyimo laha ndzhawu yinga ringanelangiki, kambe ati tirhisiwi tani hi ti terminal valves tani hileswi tinga hambanisiwaka.

- Tiyisisa ku fambisana ka flange (xikombiso ANSI, DIN) ku tiyisisa ku pfariwa.

- Papalata ku tiyisisa ngopfu ti flange bolts ku sivela ku onhaka ka miri wa muchini.

- Yi vekiwile eka sisiteme leyi nga na ku rhurhumela kutsongo ka tiphayiphi ku sivela ku olova.

3. Ndlela yo Pfala.

Valve ya lug butterfly yinyika xisirhelelo xo tiya hikokwalaho ka swihlanganisi swa threaded na ti safety bolts, kutiyisisa leswaku ku tirha handle ka leak xikan’we naku sivela ku tlhelela endzhaku ka fluid.

Kuhambana na sweswo, wafer type butterfly valve yititshege hi compression exikarhi ka ti flanges timbirhi kuva yi fikelela ku pfariwa loku tshembekaka, hikokwalaho yifanele ku vekiwa yi fambelana hiku hetiseka na phayiphi kuva yi papalata ku nga ringani na ku vupfa.

4. DN&PN

- Wafer eka ti valve ta maphaphatani hi ntolovelo yiva yitsongo kutlula DN600, naswona ti single flange butterfly valves tinga tirhisiwa eka ti diameters letikulu. Hi ntolovelo ti lulamerile eka swiyimo laha ntshikelelo wu nga ≤ PN16.

-Valva ya lug butterfly yina diameter leyikulu naswona yinga khoma swiyimo swale henhla swa ntshikelelo, kuya fika eka PN25, hikuva ku vekiwa ka valve ya lug butterfly swi sirhelelekile swinene.

5. Cost

Ti valve ta lug butterfly na ti valve ta wafer butterfly tihambana hiku durha.

Ti valve ta wafer butterfly hi ntolovelo ti durhi ngopfu hikuva tina ti design to olova, ti lulamisiwa hiku olova naswona tilava swilo swintsongo.

Valve ya lug butterfly yi lava ku threading, hikokwalaho endlelo ro endla hi muchini ri rharhanganile swinene.

III. Cku katsiwa

Havumbirhi bya ti lug butterfly valves na wafer butterfly valves switirhisiwa ku lawula ku khuluka ka mati, kambe kuna ku hambana lokukulu eka dizayini, ku vekiwa, ku pfariwa, diameter, pressure rating, na ntsengo exikarhi ka leswimbirhi. Loko ku hlawuriwa, swinga kumiwa kuya hi swilaveko swokarhi: loko ku laveka ku hambanisiwa nkarhi na nkarhi naku hlayisiwa, swakahle ku hlawula muxaka wa ndleve leyi humelaka ehandle; Loko ndzhawu yitsongo naswona ntsengo wuri xiphiqo, wafer on design yifaneleka swinene. Ku twisisa ku hambana loku swinga ku pfuna ku hlawula ti valve leti fambelanaka swinene naku fikelela vulawuri bya kahle naku tshembheka bya ku khuluka.TWSa hi mutirhisani la tshembekaka ntsena eka xiyimo xa le henhlati valve ta phaphatani, kambe yi tlhela yi va na nhlengeleto wo enta wa xithekiniki na swintshuxo leswi vupfeke eka tinsimu tati valve ta gede, ti valve to kambela, valve yo humesa moya, etc. Ku nga khathariseki leswaku vulawuri bya mati byi ku lava yini, hi nga ku nyika nseketelo wa valve ya xiphurofexinali na leyi heleleke ya xiyimo xin’we. Loko u ri na xikongomelo xo tirhisana kumbe ku burisana hi xithekiniki, hi kombela u ntshunxeka ku vulavurisana na hina nkarhi wihi na wihi.
