Ngaba iiValve zeBhola zingasetyenziselwa iSteam: Isikhokelo esipheleleyo

Iivalvu zebhola zisetyenziswa kakhulu kwizicelo zoshishino, kodwa ukuhambelana kwazo neenkqubo zomphunga kudla ngokuphakamisa imibuzo. Eli nqaku liphonononga ukuba iivalvu zebhola ziyakwazi na ukumelana nomphunga, izibonelelo zazo, iintlobo ezifanelekileyo, kunye nendlela yokukhetha abavelisi abathembekileyo.

Yintoni iValve yeBhola

Ivalvu yebhola yivalvu ejika ngekota esebenzisa ibhola engenanto, eneembobo, ejikelezayo ukulawula ukuhamba kolwelo. Xa umngxuma webhola uhambelana nombhobho, ukuhamba kwawo kuvumelekile; ukuwujikelezisa ngama-90 degrees kuyawuvala ukuhamba kwawo. Zaziwa ngokuqina nokuvala ngokuqinileyo, iivalvu zebhola zithandwa kakhulu kwimizi-mveliso yeoyile, igesi, amanzi kunye neekhemikhali.

Iimpawu zeSteam

Umphunga yigesi enamandla aphezulu eveliswa ngamanzi ashushu. Iimpawu zayo eziphambili ziquka:

• Ubushushu obuphezuluIinkqubo zomphunga zihlala zisebenza kwi-100°C–400°C.
• Ukutshintshatshintsha koxinzelelo: Imigca yomphunga inokuba notshintsho olukhawulezileyo kuxinzelelo.
• Ukugqwala: Ukungcola emanzini kunokubangela i-condensate erhabaxa.

Ezi mpawu zifuna iivalvu ezinezixhobo eziqinileyo, uzinzo lobushushu, kunye nokutywinwa okuthembekileyo.

Iingenelo zeevalvu zebhola kwiinkqubo zomphunga

1. Ukusebenza ngokukhawuleza: Ukujika kweedigri ezingama-90 kwenza ukuba ucime ngokukhawuleza, nto leyo ebaluleke kakhulu xa ukhupha umphunga ngequbuliso.
2. Ukutywina Okugqwesileyo: Izitulo ze-PTFE okanye ze-graphite ziqinisekisa ukusebenza okungenamanzi phantsi koxinzelelo oluphezulu.
3. Ukuqina: Ulwakhiwo lwentsimbi engenasici okanye i-alloy lumelana nokugqwala kunye noxinzelelo lobushushu.
4. Ukugcinwa Okuphantsi: Uyilo olulula lunciphisa ukuguguleka kunye nexesha lokungasebenzi.

Iintlobo zeeValve zeBhola ezilungele iSteam

Ayizizo zonke iivalvu zebhola ezihambelana nomphunga. Iindidi eziphambili ziquka:

1. Iivalvu zeBhola eziPheleleyo: Nciphisa ukwehla koxinzelelo kwimigca yomphunga ohamba ngamandla.
2. Iivalvu zeBhola ezidadayo: Ilungele iinkqubo zomphunga ezinoxinzelelo oluphantsi ukuya koluphakathi.
3. Iivalvu zeBhola ezifakwe kwiTrunnion: Phatha umphunga oxinzelelweyo ophezulu nge-torque ephantsi yokusebenza.
4. Iivalvu zobushushu obuphezulu: Izihlalo eziqinisiweyo (umz., ezifakwe isinyithi) kunye neziqu ezinde ukuze zikhusele izitywini.

Abavelisi beValve yeBall Steam ehamba phambili

Abavelisi abadumileyo baquka:

• I-Spirax Sarco: Igxile kwizinto ezisetyenziswa kwinkqubo yomphunga.
• Velan: Inika iivalvu zebhola ezinoxinzelelo oluphezulu, ezinobushushu obuphezulu.
• I-Swagelok: Yaziwa ngeevalvu ezenziwe ngobuchule obuchanekileyo.
• UEmerson (uFisher): Ibonelela ngezisombululo zomphunga ezikumgangatho wemizi-mveliso.
• I-Newsway Valve (NSW): Enye yeIimpawu ezilishumi eziphezulu zeValve zaseTshayina

Ukukhetha iFektri yeValve yeSteam Ball

Xa ukhethaumenzi wevalvu yebhola, cinga:

1. Iziqinisekiso: ISO 9001, API 6D, okanye ukuthobela i-PED.
2. Umgangatho wezinto eziphathekayoIivalvu kufuneka zisebenzise intsimbi engagqwaliyo okanye ii-alloys ze-ASTM.
3. Imigangatho yoVavanyo: Qinisekisa ukuba iivalvu zivavanyelwa ukujikeleza kwe-hydrostatic kunye ne-thermal.
4. Ukwenziwa ngokwezifiso: Khangela iifektri ezibonelela ngoyilo olukhethekileyo lwezicelo zomphunga ezikhethekileyo.
5. Inkxaso Emva KokuthengisaIziqinisekiso kunye noncedo lobuchwephesha zibalulekile.

Isiphelo

Iivalvu zebhola zingasetyenziselwa iinkqubo zomphunga xa zenziwe ngezinto ezishushu kakhulu kunye nokuvala okuqinileyo. Ukukhetha uhlobo olufanelekileyo kunye nomenzi othembekileyo kuqinisekisa ukhuseleko, ukusebenza kakuhle, kunye nobude bexesha kwiindawo ezifuna umphunga. Soloko uqinisekisa iinkcukacha nomthengisi wakho ukuze uhambelane nokusebenza kwevalvu neemfuno zenkqubo yakho.
