Tivalvua ti tirhisiwi ngopfu eka tiindasitiri to hambana-hambana ntsena, kambe ti tlhela ti tirhisa tindhawu to hambana-hambana, naswona tivalvu tin’wana eka tindhawu to tirhela to tika ti tala ku va ni swiphiqo. Tanihi leswi tivalvu ti nga switirhisiwa swa nkoka, ngopfu-ngopfu eka tivalvu tin’wana letikulu, swa tika swinene ku ti lunghisa kumbe ku ti cinca loko se ku ri ni xiphiqo. Hikwalaho, i swa nkoka ngopfu-ngopfu ku endla ntirho lowunene wa ku lunghisa ni ku lunghisa siku na siku. A hi languteni switsundzuxo swin’wana mayelana ni ku hlayisa valve.
1. Ku hlayisiwa na ku kamberiwa ka siku na siku kati- valve
1. Valve yifanele ku hlayisiwa eka kamara leri omeke naswona ri nghenaka moya, naswona makumu hamambirhi ya ndlela ya fanele ku pfariwa.
2. Tivalvuleyi hlayisiweke nkarhi woleha yifanele ku kamberiwa nkarhi na nkarhi, thyaka rifanele ku susiwa, naswona mafurha ya anti-rust yafanele ku cheriwa ehenhla ka ndzhawu yo lulamisa.
3. Endzhaku ko veka, ku fanele ku endliwa ku kamberiwa nkarhi na nkarhi, naswona swilo leswikulu swo kambela hi leswi:
(1) Ku onhaka ka ndhawu yo pfalela.
(2) Ku onhaka ka thyaka ra trapezoidal ra nsinya na nati ya nsinya.
(3) Ku nga khathariseki leswaku filler yi hundzeriwile hi nkarhi naswona a yi tirhi, loko yi onhakile, yi fanele ku cinciwa hi nkarhi.
(4) Endzhaku ka loko valve yi lulamisiwile no hlanganisiwa, ku fanele ku endliwa xikambelo xa matirhelo ya ku pfalela.
2. Ntirho wo hlayisa loko valve yi cheriwile mafurha
Ku hlayisiwa ka xiphurofexinali kavalveemahlweni na le ndzhaku ka ku welda na vuhumelerisi swi tlanga xiave xa nkoka eka vukorhokeri bya valve eka vuhumelerisi na matirhelo, naswona ku hlayisiwa lokunene na loku hlelekeke na loku tirhaka ku ta sirhelela valve, ku endla leswaku valve yi tirha hi ntolovelo na ku lehisa vutomi bya vutirheli bya valve. Ku hlayisa tivalvu swi nga ha vonaka swi olova, kambe a swi tano. Hakanyingi ku ni swiyenge leswi honisiwaka swa ntirho.
1. Loko valve yi cheriwa mafurha, xiphiqo xa ku cheriwa mafurha hakanyingi a xi honisiwa. Endzhaku ka loko xibamu xo chela mafurha xi cheriwile mafurha, mutirhisi u hlawula valve na ndlela yo hlanganisa ku chela girisi ku endla ntirho wo chela girisi. Kuna swiyimo swimbirhi: hi tlhelo rin’we, nhlayo ya grease injection i yitsongo, grease injection ayi enelangi, naswona ndzhawu yo pfalela yi hatlisa ku ambala hikokwalaho ka ku pfumaleka ka lubricant. Hi hala tlhelo, ku cheriwa ka mafurha ku tlula mpimo swi vanga thyaka. Leswi swivangiwa hikuva akuri na xibalo lexi kongomeke xa vuswikoti byo pfalela bya ti valve tohambana hambana kuya hi muxaka wa muxaka wa valve. Vuswikoti byo pfalela byi nga hlayiwa kuya hi vukulu na muxaka wa valve, kutani nhlayo leyi faneleke ya mafurha yinga cheriwa hindlela leyi ringaneleke.
Tlhandlakambirhi, loko valve yi cheriwa mafurha, hakanyingi xiphiqo xa ntshikelelo xa honisiwa. Hi nkarhi wa ntirho wa grease injection, ntshikelelo wa grease injection wu cinca nkarhi na nkarhi eka tinhlohlorhi na minkova. Ntshikelelo wu le hansi swinene, ntshikelelo wa ku vupfa kumbe ku tsandzeka ka seal wu le henhla swinene, ndhawu yo chela girisi yi pfalekile, girisi eka seal yi nonokile, kumbe ring yo pfalela yi pfaleriwile hi bolo ya valve na valve plate. Hi ntolovelo, loko ntshikelelo wa ku cheriwa ka mafurha wuri ehansi swinene, mafurha lawa ya cheriweke ngopfu ngopfu ya khulukela ehansi ka xigwitsirisi xa valve, leswi hi xitalo swihumelelaka eka ti valve letintsongo ta gede. Loko ntshikelelo wa ku cheriwa ka girisi wu ri ehenhla swinene, hi tlhelo rin’we, kambela nozzle yo chela girisi, kutani u yi cinca loko khumbi ra girisi ri pfalekile; Hi hala tlhelo, ku nonon’hwa ka girisi, laha ku tirhisiwaka xitofu xo basisa ku olovisa mafurha yo pfalela lama tsandzekeke hi ku phindha-phindha ivi ku siviwa hi girisi leyintshwa. Ku engetela kwalano, muxaka wo pfalela na switirhisiwa swo pfalela switlhela swi khumba ntshikelelo wa mafurha, swivumbeko swohambana hambana swo pfalela swina ntshikelelo wohambana wa mafurha, hiku angarhela, ntshikelelo wa mafurha ya hard seal wule henhla kutlula soft seal.
Ku endla ntirho lowu nga laha henhla ku tshembiwa leswaku swi pfuna swinene eka ku lehisa vutomi bya vutirheli bya...valve, naswona hi nkarhi lowu fanaka, swi nga tlhela swi hunguta swiphiqo swo tala leswi nga lavekiki.
