Nhlamuselo ya vuxokoxoko bya ndlela leyinene yo tirhisa valve

Ku lunghiselela ku nga si endliwa vuhandzuri

Loko unga se tirhisa valve, ufanele ku hlaya swiletelo swaku tirhisa hi vukheta. Loko unga se tirha, ufanele kuva uri erivaleni hi tlhelo ra ku khuluka ka gasi, ufanele ku nyikela nyingiso ku kambela swikombiso swa ku pfula na ku pfala ka valve. Languta ku languteka ka valve ku vona loko valve yi tsakamile, loko kuri na ndzhongho lowu faneleke ku endliwa drying treatment; loko ku kumiwa leswaku ku na swiphiqo swin’wana leswi faneleke ku langutisiwa hi nkarhi, a swi nge tirhisiwi hi ku tsandzeka. Loko valve ya gezi yinga tirhi kuringana kutlula 3 wa tinhweti, clutch yifanele ku kamberiwa loko yinga se sungula, tiyisisa leswaku handle yile ka xiyimo xa manual, kutani u kambela insulation, steering na wiring ya gezi ya motor.

Ku Tirha Hi Ndlela Leyi Faneleke Ka Tivalvu Ta Manual

Ti valve ta manual i ti valve leti tirhisiwaka ngopfu, naswona mavhilwa ya tona ya mavoko kumbe swikhomo swi endliwe hiku landza matimba ya vanhu lawa ya tolovelekeke, ku tekeriwa enhlokweni matimba ya ndzhawu yo pfalela xikan’we na matimba lawa ya lavekaka yo pfala. Hikwalaho, a wu nge tirhisi lever yo leha kumbe voko ro leha ku fambisa pulati. Vanhu van’wana va toloverile ku tirhisa voko ra plate, va fanele ku nyikela nyingiso lowukulu eka ku pfuleka ka valve ku fanele ku tirhisiwa ku sindzisa ku olova, ku papalata matimba yo tlula mpimo, leswi endlaka leswaku ku pfuleka na ku pfala ka valve, matimba ya fanele ku va ya rhetela, ku nga ri ku khumbeka. Ku pfuriwa kun’wana ka impact naku pfala swiphemu swa valve ya ntshikelelo wale henhla swi tekiwile tani hi impact leyi naswona ti valve totala tinga ringani na Gang.

Loko valve yi pfulekile hiku hetiseka, handwheel yifanele ku hundzuriwa nyana, leswaku ti threads exikarhi ka tight, leswaku kunga olovi ku onhaka. Swativalvu ta gede ya nsinya leti tlakukeke, .ku tsundzuka ku pfuleka hiku hetiseka naku pfala hiku hetiseka loko xiyimo xa nsinya, ku papalata ku pfuleka hiku hetiseka loko ku khumbeka eka dead center. Naswona swa olova ku kambela loko swi tolovelekile loko swi pfariwile hi ku helela. Loko hofisi ya valve yi timiwile, kumbe spool seal leyi nghenisiweke exikarhi ka swilo leswikulu, xiyimo xa nsinya lexi pfalekeke hiku hetiseka xifanele ku cinciwa. Ku onhaka ka vuandlalo byo pfalela valve kumbe handwheel ya valve.

Xikombiso xa ku pfuleka ka valve: valve ya bolo, .valve ya phaphatani leyi nga exikarhi, plug valve stem top surface groove parallel na channel, leswi kombisaka leswaku valve eka xiyimo lexi pfulekeke hi ku helela; loko nsinya wa valve wu rhendzeleka 90 ° kuya eximatsini kumbe exineneni, groove yi perpendicular eka channel, leswi kombaka leswaku valve yi le ka xiyimo lexi pfalekeke hi ku helela. Ti valve tin’wana ta bolo, ti butterfly valves, ti plug valves kuya eka wrench na channel parallel kuya eku pfulekeni, vertical for closed. Ti valve ta tindlela tinharhu, ta mune tifanele ku tirhisiwa kuya hi ku funghiwa ka ku pfula, ku pfala na ku tlherisela endzhaku. Endzhaku ka loko vuhandzuri byi hetiwile, xikhomela lexi fambafambaka xifanele ku susiwa.

Ku tirha kahle ka ti check valves

Leswaku ku papalatiwa matimba ya le henhla ya ku khumbeka lama vumbiweke hi nkarhi wo pfalavalve yo kambela leyi tshameke hi rhaba, valve yifanele ku pfala hiku hatlisa, xisweswo ku sivela kuvumbiwa ka rivilo lerikulu ra backflow, leswinga xivangelo xa ntshikelelo wa impact lowu vumbiwaka loko valve yi pfariwile hi xitshuketa. Hikokwalaho, rivilo ro pfala ra valve rifanele ku fambelanisiwa kahle na decay rate ya downstream medium.

Loko rivilo ra xitirhisiwa lexi khulukaka ri hambana eka ndzhawu yo anama, rivilo ra le hansi ra ku khuluka a ri enelanga ku sindzisa elemente yo pfala ku yima leyi tiyeke. Eka xiyimo lexi, ku famba ka elemente yo pfala ku nga hungutiwa eka mpimo wo karhi wa xitsalo xa yona. Ku rhurhumela hi xihatla ka elemente yo pfala swinga endla leswaku swiphemu leswi fambafambaka swa valve swi hatlisa ngopfu, leswi endlaka leswaku valve yi tsandzeka ka ha ri na nkarhi. Loko medium yi ri karhi yi ba, ku rhurhumela hi xihatla ka elemente yo pfala na kona ku vangiwa hi ku kavanyeteka lokukulu ka medium. Kun’wana na kun’wana laha leswi swinga tano, ti check valves tifanele kuva laha kunga hungutiwa ku kavanyeteka kale xikarhi.
