Tinhla ta Nkoka ta Swihlawulekisi swa ku Vekiwa ka Valve ya Tiphayiphi

I. Ku lunghiselela ka le mahlweni ka ku vekiwa

1. Languta modele wa swihlawulekisi swa valve, levele ya ntshikelelo, na ku tivisiwa ka tlhelo ra ku khuluka ku tiyisisa leswaku swi fikelela swilaveko swa dizayini.

2. Languta ku basa ka xigwitsirisi xa miri wa valve naswona susa switirhisiwa swo sirhelela ku paka na swilo swa matiko mambe.

3. Ti valve to hlanganisa ta butt welding tifanele ku endliwa ka ha ri emahlweni na ti grooves, naswona ti flange connection valves tifanele ku kambela vutshembeki bya sealing surface.

II. Vulawuri bya Nkongomiso wa ku Vekiwa

1. Valava ya globe navalve yo kambela ku tlakusa loku yimisiwekeyifanele ku vekiwa hiku hetiseka eka tlhelo leri kombisiweke hi museve eka miri wa valve.

2. Hi ku ya hi nsinya wa nawu, .valve ya nsinya lowu nga tlakukiki, muxaka wa mati ya phaphatani valve, naswona tivalvu ta bolo ti nga vekiwa eka matlhelo hamambirhi, kambe nyingiso wu fanele ku nyikeriwa leswaku ku olova ku tirha.

3. Ti valve ta gezi / pneumatic ti lava ku hlayisa ndzhawu yo tirha na ku hlayisiwa ka actuator.

III. Swihlawulekisi swa ku Vekiwa ka Welding

1. Valve ya butt welding yifanele ku tshama yi pfulekile hafu hinkarhi wa welding kuva yi sivela ku jamming loku vangiwaka hi thermal deformation.

2. Tirhisa argon arc welding ku endla base, naswona lawula mahiselo ya interlayer leswaku yanga hundzi mahiselo lawa ya ringanyetiweke ya valve.

3. Endzhaku ko welda, valve yifanele ku kamberiwa hindlela ya ntirho ku tiyisisa leswaku yi pfula naku pfala hindlela ya ntolovelo.

IV. Tinhla ta Nkoka ta Swihlanganisi swa Flange

1. Swiphemu swo pfalela swa flange swi tshama swi ri parallel, naswona ku hambuka lokukulu loku pfumeleriwaka a ku hundzi 0.15% wa dyayimeta ya le handle ya flange.

2. Gasket yifanele ku vekiwa exikarhi, ti bolts tifanele ku tiyisiwa hi symmetrically naku ringana, naswona torque leyi ringanyetiweke yifanele ku fikeleriwa kanharhu.

3. Ti boluti to hlanganisa ta ti valve ta mahiselo yale henhla tifanele ku tiyisiwa kambirhi eka xiyimo xo hisa.

V. Vulawuri bya Khwalithi

1. Xikambelo xa matimba na xikambelo xo pfalela swa laveka endzhaku ka ku vekiwa.

2. Loko u hlantswa sisiteme, valve yo lawula, flow meter na switirhisiwa swin’wana swifanele ku hundza.

3. Tata rhekhodo ya ku vekiwa, ku katsa na datha ya nkoka yo fana na nomboro ya xiyimo xa valve, ntshikelelo wa xikambelo, torque yo tirha, na swin’wana.

Xiya: Valve ayi fanelanga kutirhisiwa tani hi ndzhawu yo seketela phayiphi. Ti valve letikulu ti lava furemu yo seketela leyi hambaneke. Endzhaku ko vekiwa, valve yifanele kuva yiri eka xiyimo xo pfala hiku hetiseka naswona yi sirheleriwa kuva yi papalata ku onhaka ka cross-operation.
