Iimpawu eziphambili kunye nokusetyenziswa kweevali zeBhola

I-valves yebholaLuhlobo lwe-valve yekota yekota esebenzisa i-hollow, i-ireyithwe, kunye nebhola ehlekisayo yokulawula ukuhamba kweembiza okanye igesi kuyo. Xa ivalve ivulekile, umngxunya kwibhola uhambelana nolwalathiso lokuhamba, ukuvumela i-medium sele idlulise. Xa ivalve ivaliwe, ibhola ijikelezwe i-90 degrees, ke umngxunya ujikelezile ukuhamba, ukuyivala. Isibambo okanye i-lever isetyenziselwa ukusebenza ivalve idla ngokuhambelana nendawo yomngxunya, ukubonelela ngokuboniswa okuqinisekileyo kwemeko ye-valve.

Zeziphi izinto eziphambili zeevalves zebhola:

1. Ukuqina: I-valve yebhola yaziwa ngobomi babo obude kunye nokuthembeka, kwanamathuba okuhlala ixesha elide lokuchitha.
2. Ukusebenza ngokukhawuleza: Bangavulwa okanye bavaliwe ngokukhawuleza nge-90-degree dep.
3. Ukutywinwa ngokuqinileyo: IVils zeBhola ibonelela ngeepropathi ezibalaseleyo zokutywina, ezenza bafaneleke kwizicelo ezifuna ukuvuza kwe-zero.
4. Uqwalaselo: Banokuphatha uluhlu lwemithombo yeendaba, kubandakanya ulwelo, igesi, kunye nokutyibilika.
5. Ulondolozo olusezantsi: Ngenxa yoyilo lwabo olulula, i-valve yebhola ifuna ulondolozo oluncinci.

Iindidi zeevalva zeBhola:

1. Ivalve yebhola epheleleyoUbungakanani bobuqhetseba bufana nombhobho, kubangela ilahleko encinci. Ilungele izicelo ezifuna ukuhamba okungazibandakanyi.
2. I-Port yeBhola yePort yePort: Ubungakanani bobuqhetseba buncinci kunombhobho, onokubangela isithintelo sokuhamba kodwa sinengqondo ngakumbi kwaye ineendleko.
3. I-V-Port yeBholve yebholaIbhola ine-v-bored ye-v-i-v, ivumela ulawulo lokuhamba oluchanekileyo. Ihlala isetyenziswa kwizicelo zokupheka.
4. I-valve yebhola yebhola: Ibhola ayilungiswanga kwaye ibanjelwe kwiindawo zevalve. Ifanelekile kwizicelo zoxinzelelo oluphantsi.
5. I-Trunnion Ibhotile yebholaIbhola ibambekele phezulu nangaphezulu, iyenza ilungele uxinzelelo oluphezulu kunye nokusetyenziswa kwedayam.
6. I-Potli-Port Polve yeBhola yePort: Inika izibuko ezininzi (zihlala zintathu okanye ezine) zokuphambukisa okanye zokuxuba.

Izicelo:

I-valves ichibi zisetyenziswa ngokubanzi kumashishini ahlukeneyo, kubandakanya:

-Ioyile kunye negesi: Ukulawula ukuhamba kweoyile ye-crude, irhasi yendalo, kunye nezinye ii-hydrocarbons.
-Unyango lwamanzi: Kwimibhobho yamanzi okusela, amanzi amdaka, kunye neenkqubo zonkcenkceshelo.
-Ukuqhubekeka kwamachiza: Ukuphatha iichemicals ezinobungozi kunye nezinobungozi.
-HvacUkufudumeza, umoya ovuthuzayo, kunye neenkqubo zomoya.
-Amayeza: Iinkqubo ezingenamsebenzi necocekileyo.
-Ukutya kunye nesiselo: Ukuqhubela phambili kunye nemigca yokupakisha.

IZIBONELELO ZOKWENZA IVULWO ZABALA:

-Ukusebenza ngokulula: Ilula kwaye ikhawuleza ukuvula okanye ukuvala.
-Uyilo lweClamputha: Kuthatha indawo encinci xa kuthelekiswa nezinye iintlobo ze-veli.
-Uxinzelelo oluphezulu kunye nokunyamezelana kobushushu: Ilungele iindawo ezifuna izinto.
-Ukuhamba kwe-bidirectial: Ngaba unokuphatha ukuhamba kwezinto zombini.

Izinto ezingalunganga:

-Ayilungelanga i-throttling: Ngelixa zinokusetyenziselwa ukuphosa, ukusebenzisa ixesha elide kwizikhundla ezivulekileyo ezivulekileyo kunokubangela ukunxiba kunye nokukrazula.
-Ukulawulwa okunqongophelelo ngokuchanekileyo: Xa kuthelekiswa ne-globe okanye i-Inaliti, ivalves yeBhola inikezela ngolawulo lokuhamba kancinci.

IZIPHUMO ZOBUCHULE BENKONZO:

I-valve zebhola zenziwa ngeendlela ezahlukeneyo, kubandakanya:

-Yenziwe ngentsimbi eshayinayo: Ukuxhathisa i-corrosion kunye nokuqina.
-Ubhedu: Izicelo zeenjongo ngokubanzi.
-I-pvc: Kwindawo ezonakalisayo kunye nezicelo zoxinzelelo oluphantsi.
-I-carbon yensimbi: Ukufumana uxinzelelo oluphezulu kunye nosetyenziso oluphezulu lobushushu.

Ukuqwalaselwa kokukhetha:

Xa ukhetha ivalve yebhola, cinga ngezinto ezinje:

-Inqanaba loxinzelelo: Qinisekisa ivalve inokuphatha uxinzelelo lwenkqubo.
- Uluhlu lobushushu: jonga ukuhambelana kwe-valve kunye neqondo lokushisa.
-Imithombo yeendaba: Qinisekisa ukuba izinto zeValve zihambelana nolwelo okanye igesi ikhutshiwe.
-Usayizi kunye nohlobo lwezibuko: Khetha ubungakanani obufanelekileyo kunye nohlobo lwezibuko zesicelo sakho.

I-valves yebhola kukhetho oluqinisekileyo noluthembekileyo kwizicelo ezininzi zolawulo lwamanzi, ukuhambisa ibhalansi yokusebenza, ukuqina, kunye nokusetyenziswa ngokulula.
