Valve tani hi xitirhisiwa yi velekiwile kuringana magidi ya malembe

Valve ya konai xitirho lexi tirhisiwaka eku hundziseni ni le ku lawuleni ka gasi ni mati lexi nga ni matimu ya kwalomu ka gidi ra malembe.

Sweswi, eka sisiteme ya tiphayiphi ta mati, valve yo lawula i elemente yo lawula, naswona ntirho wa yona lowukulu i ku hambanyisa switirhisiwa na sisiteme ya tiphayiphi, ku lawula ku khuluka, ku sivela ku tlhelela endzhaku, ku lawula na ku humesa ntshikelelo. Leswi swinga swa nkoka swinene ku hlawula valve yo lawula leyi faneleke swinene eka sisiteme ya tiphayiphi, switlhela swiva na nkoka swinene ku twisisa swihlawulekisi swa valve xikan’we na magoza na xisekelo xo hlawula valve.

Ntshikelelo wa vito wa valve

Ntshikelelo wa vito wa valve wu kombetela eka dizayini leyi nyikiweke ntshikelelo lowu fambelanaka na matimba ya michini ya swiphemu swa tiphayiphi, hi leswaku, i ntshikelelo wo tirha lowu pfumeleriwaka wa valve eka mahiselo lawa ya boxiweke, leswi fambelanaka na swilo swa valve. Ntshikelelo wa ntirho awu fani, hikokwalaho, ntshikelelo wa vito i parameter leyi titshegeke hi material ya valve naswona yi fambelana na mahiselo lawa ya pfumeleriwaka yo tirha na ntshikelelo wo tirha wa material.

Valve i xitirhisiwa eka medium circulation system kumbe pressure system, leyi tirhisiwaka ku lulamisa ku khuluka kumbe ntshikelelo wa medium. Mintirho yin’wana yi katsa ku pfala kumbe ku pfula media, ku lawula ku khuluka, ku cinca tlhelo ra ku khuluka ka media, ku sivela ku tlhelela endzhaku ka media, na ku lawula kumbe ku humesa ntshikelelo.

Mintirho leyi yi fikeleriwa hiku lulamisa ndzhawu ya ku pfala ka valve. Ku lulamisiwa loku ku nga endliwa hi voko kumbe hi ku tisungulela. Ku tirha hi voko swi tlhela swi katsa ntirho wo lawula drive hi voko. Ti valve leti tirhisiwaka hi mavoko ti vuriwa ti manual valves. Valve leyi sivelaka ku tlhelela endzhaku yi vuriwa check valve; leyi lawulaka ntshikelelo wa relief yi vuriwa safety valve kumbe safety relief valve.

Kufikela sweswi, indasitiri ya ti valve yi kotile ku humelerisa nxaxamelo lowu heleleke wati valve ta gede, tivalvu ta globe, tivalvu ta throttle, tivalvu ta tiplagi, tivalvu ta bolo, tivalvu ta gezi, tivalvu to lawula diaphragm, tivalvu to kambela, tivalvu ta vuhlayiseki, tivalvu to hunguta ntshikelelo, swirhalanganyi swa mpfula na tivalvu to pfala hi xihatla. Switirhisiwa swa valve swa swiyenge swa 12, ku tlula 3000 wa timodeli, na ku tlula 4000 wa swihlawulekisi; ntshikelelo lowukulu wo tirha i 600MPa, diameter yale henhla ya nominal i 5350mm, mahiselo yale henhla yo tirha i 1200°C, mahiselo ya le hansi yo tirha i -196°C, naswona xitirhisiwa lexi tirhaka i Mati, mpfula, oyili, gasi ya ntumbuluko, switirhisiwa swo tiya leswi onhaka (ku fana na nitric acid leyi hlanganisiweke, sulphuric acid ya le xikarhi, na swin’wana).

Nyikela nyingiso eka ku hlawuriwa ka valve:

1. Leswaku ku hungutiwa vuenti lebyi funengetaka misava bya phayiphi, .valve ya phaphatanihi ntolovelo yi hlawuriwa eka phayiphi ya dyayimeta leyikulu; ku pfumaleka lokukulu ka valve ya phaphatani hileswaku pulati ya phaphatani yi teka xiphemu xo karhi xo tsemakanya xa mati, leswi engetelaka ku lahlekeriwa ko karhi ka nhloko;

2. Tivalvu leti tolovelekeke ti katsati valve ta phaphatani, ti valve ta gede, ti valve ta bolo na ti plug valve, na swin’wana na swin’wana Nxaxamelo wa ti valve leti tirhisiwaka eka netiweke ya mphakelo wa mati wu fanele ku tekeriwa enhlokweni eka ku hlawuriwa.

3. Ku hoxiwa na ku lulamisiwa ka ti ball valves na ti plug valves swa tika naswona swa durha, naswona hi ntolovelo swi lulamerile eka tiphayiphi letintsongo na ta le xikarhi. Valve ya bolo na valve ya plug swi hlayisa swipfuno swa valve ya gede yin’we, ku lwisana na ku khuluka ka mati lamantsongo, ku pfariwa loku tshembekaka, goza ro olova, matirhelo yo olova na ku hlayisiwa. Valve ya plug na yona yina swipfuno leswi fanaka, kambe xiphemu xo hundza mati ahi xirhendzevutani lexi hetisekeke.

4. Loko swi nga ri na vuyelo byintsongo eka vuenti bya misava yo funengeta, ringeta ku hlawula valve ya gede; ku tlakuka ka valve ya gede ya gezi valve ya gede yo yima ya dyayimeta leyikulu ku khumba vuenti lebyi funengetaka misava bya phayiphi, naswona ku leha ka valve ya gede leyi nga etlhelo ka dyayimeta leyikulu ku engetela ndhawu leyi nga etlhelo leyi tekiweke hi phayiphi naswona ku khumba malunghiselelo ya tiphayiphi tin’wana ;

5. Emalembeni ya sweswinyana, hikokwalaho ka ku antswisiwa ka thekinoloji yo hoxa, ku tirhisiwa ka resin sand casting swinga papalata kumbe ku hunguta ku lulamisiwa ka michini, hindlela yaleyo swihunguta ku durha, hikokwalaho ku koteka ka ti ball valves leti tirhisiwaka eka tiphayiphi ta diameter leyikulu swifanele ku lavisisiwa. Loko kuri demarcation line ya caliber size, yifanele ku tekeriwa enhlokweni no avanyisiwa kuya hi xiyimo xokarhi.
