Kutheni ukhetha iivalvu zebhola

1. Kulula ukuyisebenzisa kwaye ikhawuleza ukuyivula nokuyivala.

Jikelezisa nje isiphatho okanye i-actuator ngama-90 degrees (ikota yokujika) ukuze utshintshe ukusuka ekuvulekeni ngokupheleleyo ukuya ekuvalekeni ngokupheleleyo okanye ngokuphambeneyo. Oku kwenza ukusebenza kokuvula nokuvala kube lula kakhulu, kwaye kufanelekile ngakumbi kwiimeko apho kufuneka ukuvulwa nokuvalwa rhoqo okanye ukuvalwa okungxamisekileyo.

2. Ukusebenza kakuhle kokutywina

Xa ivaliwe ngokupheleleyo, ibhola idibana ngokuqinileyo nesihlalo sevalvu, inika isitywino esijikelezayo (singatywina nokuba i-medium iphuma kweliphi icala), ithintela ngokufanelekileyo ukuvuza. Iivalvu zebhola ezisemgangathweni ophezulu (ezifana nezo zinezitywino ezithambileyo) zinokungaphumi manzi, zihlangabezane nemigangatho engqongqo yokhuseleko lokusingqongileyo kunye nokhuseleko.

3. Inokumelana nokugeleza okuphantsi kakhulu kwaye inomthamo omkhulu wokugeleza.

Xa ivalvu ivuliwe ngokupheleleyo, ububanzi betshaneli ngaphakathi komzimba wevalvu budla ngokufana nobubanzi bangaphakathi bepayipi (ebizwa ngokuba yivalvu yebhola egcweleyo), kwaye itshaneli yebhola ikwimo ethe tye. Oku kwenza ukuba i-medium idlule phantse ngaphandle kokuphazanyiswa, ine-coefficient ephantsi kakhulu yokumelana nokuhamba kwamanzi, okunciphisa ukulahleka koxinzelelo kunye nokonga ukusetyenziswa kwamandla kweepompo okanye iicompressor.

4. Ulwakhiwo oluncinci kunye nomthamo omncinci

Xa kuthelekiswa neevalvu zesango okanye iivalvu zeglobe ezinobubanzi obufanayo, iivalvu zebhola zinesakhiwo esilula, esincinci kwaye zinobunzima obuphantsi. Oku kusindisa indawo yokufaka kwaye kuluncedo ngakumbi kwiinkqubo zemibhobho ezinesithuba esincinci.

5. Uluhlu olubanzi lwezicelo kunye nokuguquguquka okunamandla

• Ukulungelelaniswa kweendaba:Ingasetyenziswa kwiindawo ezahlukeneyo ezifana namanzi, ioyile, igesi, umphunga, iikhemikhali ezirhabaxa (kufuneka kukhethwe izinto ezifanelekileyo kunye nezitywino).
• Uluhlu loxinzelelo kunye nobushushu:Ukusuka kwi-vacuum ukuya kuxinzelelo oluphezulu (ukuya kuthi ga kumakhulu aliqela eeBha), ukusuka kubushushu obuphantsi ukuya kubushushu obuphakathi ukuya phezulu (kuxhomekeke kwizinto zokutywina, izitywino ezithambileyo zihlala zi-≤ 200℃, ngelixa izitywino eziqinileyo zinokufikelela kubushushu obuphezulu). Isebenza kuzo zonke ezi zigaba.
• Uluhlu lobubanzi:Ukususela kwiivalvu ezincinci zezixhobo (iimilimitha ezimbalwa) ukuya kwiivalvu ezinkulu zepayipi (ngaphezulu kwemitha e-1), kukho iimveliso ezivuthiweyo ezifumanekayo kuzo zonke iisayizi.
