Yintoni iValve yeBhola yePneumatic Actuator
A ivalvu yebhola ye-actuator yomoyasisixhobo esibalulekileyo sokulawula ukuhamba kwamanzi esidibanisa ivalvu yebhola kunye ne-actuator ye-pneumatic ukuze zenze ukulawulwa kolwelo, iigesi, okanye umphunga kwiinkqubo zoshishino kube ngokuzenzekelayo. Eli nqaku lichaza izinto zalo, iintlobo, iingenelo, kunye nendlela elahluke ngayo kwezinye iintlobo zeevalvu.
Yintoni i-Pneumatic Actuator
A isixhobo somoyasisixhobo soomatshini esisebenzisa umoya ocinezelweyo ukuvelisa intshukumo yeevalvu zokusebenza. Iimpawu eziphambili ziquka:
- Umsebenzi:Iguqula uxinzelelo lomoya (ngesiqhelo i-4–7 bar) ibe yintshukumo ejikelezayo okanye ethe tye.
- Izinto ezisetyenziswayo:Isilinda, i-piston, iigiya kunye nezipringi.
- Iintlobo:
–Ii-actuators zomoya ezisebenza kabini:Funa uxinzelelo lomoya ukuze uvule kwaye uvale
-Ukubuya kweNtwasahloboii-actuators zomoya:Sebenzisa umoya kwenye into kunye nesipilingi kwenye (uyilo olukhuselekileyo).
Ii-actuators zomoya zixatyiswa ngesantya sazo, ukuthembeka kwazo, kunye nokufaneleka kwazo kwiindawo ezinokuqhuma okanye ezinobushushu obuphezulu.
Yintoni iValve yeBhola
A ivalvu yebholailawula ukuhamba kwamanzi isebenzisa ibhola ejikelezayo enembobo (umngxuma) embindini wayo. Xa ihambelana nombhobho, ivumela ukuhamba kwamanzi; xa ijikeleziswa ngama-90 degrees, ivala ukuhamba kwamanzi. Iimpawu eziphambili:
- Uyilo:Iinketho eziqinileyo, ezigcweleyo okanye ezincitshisiweyo.
- Ukutywina:Ivaliwe ngokuqinileyo ngezihlalo ze-PTFE okanye zesinyithi.
- Ukuqina:Ilungele ukusetyenziswa koxinzelelo oluphezulu kunye nobushushu obuphezulu.
Iintlobo zeeValve zeBhola zePneumatic Actuator
Iivalvu zebhola ze-pneumatic zahlulwe ngokoyilo kunye nomsebenzi:
1. Ngulwakhiwo lweValve:
–Ivalvu yebhola egcweleyo:Ibholo ihambelana nobubanzi bombhobho ukuze ikwazi ukumelana nokugeleza kwamanzi kancinci.
–Ivalvu yebhola ekhutshiweyo:Imbobo encinci ukuze kubekho ukuchaneka okuphezulu kokulawula ukuhamba kwamanzi.
–Ivalvu yebhola ye-V-port:Imbobo enomfanekiso ongu-V ukuze ikwazi ukugoba kakuhle.
2. Ngokwe-Actuation:
–Ukusebenza kabini:Ifuna umoya ovulwayo xa ivula kwaye ivala.
–Ukubuya kwentwasahlobo:Ibuyela ngokuzenzekelayo kwindawo ekhuselekileyo xa umoya ulahlekile.
Iingenelo zePneumatic Actuator Ball Valves
1. Ukutywina Okugqwesileyo:Ukuvala okuqinileyo, nokuba kuphantsi koxinzelelo oluphezulu.
2. Ukusebenza ngokukhawuleza:Ukujikeleza nge-90-degree kwenza kube lula ukuvula/ukuvala imijikelo ngokukhawuleza.
3. Ulondolozo oluphantsi:Uyilo olulula oluneendawo ezimbalwa eziguga lula.
4. Ukuguquguquka:Iyahambelana neendaba ezinobundlongondlongo (ii-asidi, iigesi, umphunga).
5. Ubomi beNkonzo ende:Ayimelani nokugqwala kunye namaqondo obushushu aphezulu.
Ivalvu yeBhola yePneumatic Actuator vs. Ezinye iiValve
| Uhlobo lweValve | Umahluko oPhambili |
| Valve yeButterfly yomoya | Ilula kwaye ingabizi kakhulu kodwa ayisebenzi kakuhle ekutywineni ngoxinzelelo oluphezulu. |
| I-Valve yeSango le-Pneumatic | Ukusebenza kancinci; ilungele ukuhamba ngokupheleleyo, hayi ukugoba. |
| Ivalvu yeGlobe yePneumatic | Ingcono xa isetyenziswa ngendlela echanekileyo kodwa iphantsi kakhulu xa ixinzelelwa kwaye iyinkimbinkimbi. |
| I-ESDV (iValvu yoKuvala iXakeka) | Ibeka phambili ukuvalwa okukhawulezileyo kokhuseleko; idla ngokudityaniswa neevalvu zesango/zebhola. |
Ukusetyenziswa kweeValve zeBhola zePneumatic Actuator
1. Ioyile kunye neGesi:Ukuvala nokulawula imibhobho, iindawo zokucoca, kunye nezityalo ze-LNG.
2. Ukucubungula iikhemikhali:Phatha ulwelo olubolayo kunye nemidiya ecocekileyo kakhulu.
3. Unyango lwamanzi: Lawula amanzi okusela, amanzi amdaka, kunye neenkqubo zokunkcenkceshela.
4. Ukuveliswa koMbane:Lawula umphunga kunye namanzi okupholisa kwiiturbines.
5. Amayeza:Uyilo lwezempilo lokuphatha ulwelo olungenazintsholongwane.
Isiphelo
Iivalvu zebhola ze-actuator ze-pneumatic zibalasele kwiindawo ezinoxinzelelo oluphezulu, ubushushu obuphezulu, kunye nezokubola, zibonelela ngokutywinwa nokuthembeka okungenakuthelekiswa nanto. Ukuziqhelanisa kwazo kumashishini kuzenza zibe sisiseko seenkqubo zanamhlanje zokulawula ukuhamba kwamanzi.
