Ku hambana exikarhi ka swisirhelelo swo olova na swo tiya swa tivalvu:

Xo sungula, hambi ku ri valve ya bolo kumbe avalve ya phaphatani, na swin’wana, kuna swisirhelelo swo olova na swo tiya, teka valve ya bolo tani hi xikombiso, ku tirhisiwa ka swisirhelelo swo olova na swo tiya swa ti valve ta bolo swihambanile, ngopfu ngopfu hi xivumbeko, naswona swipimelo swa vumaki bya ti valve aswi fambelani.

Xo sungula, endlelo ra xivumbeko

Xisirhelelo xo tiya xa valve ya bolo i xisirhelelo xa nsimbi ku ya eka nsimbi, naswona bolo yo pfalela na xitulu i nsimbi. Ku lulama ka michini xikan’we na maendlelo ya tika swinene, naswona hi xitalo yitirhisiwa eka ntshikelelo wale henhla, hi ntolovelo kutlula 35MPa. Soft seals i ti seals exikarhi ka tinsimbi na letinga riki tinsimbi, kufana na nylon\PTFE, naswona swipimelo swa vumaki swafana.

Xa vumbirhi, nchumu wo pfalela

Xisirhelelo xo olova na xo tiya i xitirhisiwa xo pfalela xitulu xa valve, naswona xisirhelelo xo tiya xi endliwe hi muchini hi ku kongoma na xitirhisiwa xa xitulu xa valve ku tiyisisa ku fambelana lokunene na valve core (bolo), hi xitalo stainless steel na copper. Soft sealing swivula leswaku xitirhisiwa xo pfalela lexi nghenisiweke eka xitulu xa valve i nchumu lowu nga riki wa nsimbi, hikuva soft sealing material yina elasticity yokarhi, hikokwalaho swilaveko swa ku pakanisa ka processing switava ehansi kutlula swa hard sealing.

Xa vunharhu, endlelo ro endla swilo

Hikwalaho ka indasitiri yotala ya tikhemikhali, ndzhawu yo tirhela eka yona ya indasitiri ya michini yi rharhanganile swinene, yotala yina mahiselo yale henhla xikan’we na ntshikelelo wale henhla, ku tiya ka friction ka medium i kukulu, naswona ku bola ka matimba, sweswi thekinoloji yiyile emahlweni, kutirhisiwa ka switirhisiwa swohambana hambana swa antswa, naswona ku lulamisiwa na swin’wana swinga fambisana, leswaku valve ya bolo leyingana hard seal yi hlohleteriwile swinene.

Entiyisweni, nsinya wa nawu wa valve ya bolo ya hard seal wu fana na wa soft seal, kambe hikuva ku ri xisirhelelo exikarhi ka tinsimbi, swa laveka ku tekela enhlokweni vuxaka bya ku tiya exikarhi ka tinsimbi, xikan’we na swiyimo swa ntirho, leswaku i medium yihi leyi faneleke ku famba, na swin’wana na swin’wana Hi ntolovelo, ku nonoka swa laveka, naswona bolo na xitulu swi tshama swi ri karhi swi gayeriwa ku fikelela ku pfariwa. Xirhendzevutani xa vuhumelerisi bya hard seal ball valve xi lehe, ku lulamisiwa ka yona swi rharhanganile swinene, naswona aswi olovi ku endla ntirho wa kahle wa hard seal ball valve.

Xa vumune, swiyimo swa ku tirhisiwa

Ti soft seals hi xitalo tinga fikelela ti seals tale henhla, kasi ti hard seals tingava e henhla kumbe ehansi kuya hi swilaveko; Ti soft seals tifanele kuva tinga ngheniwi hi ndzilo, hikuva eka mahiselo yale henhla, swilo swa soft seal swita vupfa, kasi hard seal ayi na xiphiqo lexi; Hi ntolovelo swisirhelelo swo tiya swinga endliwa hi ntshikelelo wale henhla, kambe swisirhelelo swo olova aswinga endliwi; Hikokwalaho ka xiphiqo xaku khuluka ka medium, soft seal ayi tirhisiwi eka swiendlakalo swin’wana (kufana na swin’wana swa corrosive media); Valve yo hetelela ya hard seal hi xitalo yi durha kutlula valve ya soft seal. Loko kuri vumaki, akuri na ku hambana lokukulu exikarhi ka leswimbirhi, nchumu lowukulu i ku hambana exikarhi ka switulu swa valve, soft seal ayi na nsimbi, naswona hard seal i nsimbi.

Xa vuntlhanu, eku hlawuleni ka switirhisiwa

Ku hlawuriwa ka ti soft na hard seal ball valves swiseketeriwe ngopfu eka process medium, mahiselo na ntshikelelo, general medium yina ti solid particles kumbe yina ku onhaka kumbe mahiselo yale henhla kutlula 200 degrees, swikahle ku hlawula ti hard seals, diameter yi tlula 50, ku hambana ka ntshikelelo wa valve i kukulu, naswona torque ya fixed hard seal ball valve yifanele ku hlawuriwa loko fixed hard seal ball valve yifanele ku hlawuriwa torque yikulu, kunga khathariseki ti seals to olova na to tiya, levele ya sealing yinga fika eka level 6.
