Njengomvelisi ophambili weevalvu ezikumgangatho ophezulu, i-ZFA idla ngokufumana imibuzo malunga nomahluko phakathi kweentlobo ezahlukeneyo zeevalvu. Umbuzo oqhelekileyo ngulo: Yintoni umahluko phakathi kwe-aivalvu yebhabhathanekunyeivalvu yokujonga ibhabhathaneNangona zabelana ngamagama afanayo kwaye zombini zisebenzisa uyilo lohlobo lwediski, imisebenzi yazo, imisebenzi, kunye nezicelo zahlukile kakhulu.
Esi sikhokelo sijonga la mahluko aphambili, sisebenzisa ubuchule be-ZFA. Siza kugqiba ngezinto ezisisiseko—ezifana nenkcazo, uyilo, kunye nemigaqo yokusebenza. Nokuba ungunjineli, ingcali yokuthenga, okanye ingcali kushishino, eli nqaku liza kukunceda wenze isigqibo esinolwazi.
1. Yintoni iValve yeBhabhathane?
Ivalvu yebhabhathane yivalvu ejikelezayo ejikelezayo ngekota esetyenziselwa ukulawula ukuhamba okanye ukwahlukanisa imibhobho. Inediski ejikeleza ngeenxa zonke ze-axis ephakathi ukuvula okanye ukuvala indlela yokuhamba.
1.1 Indlela esebenza ngayo iValve yeBhabhatha
Ivalvu isebenza ngokujikeleza idiski ngee-degrees ezingama-90: ivuleke ngokupheleleyo, ivumela ukuhamba okungaphazanyiswanga, okanye ivalwe, ivale indlela yokuhamba. Ukujikeleza okungaphelelanga kuvumela ukugoba, okwenza ifaneleke ukulawula ukuhamba.
1.2 Izicelo Eziqhelekileyo
- Izityalo Zokucoca Amanzi
- Iinkqubo ze-HVAC
- Ukucubungula iikhemikhali
- Ishishini lokutya neziselo
2. Yintoni iValve yokujonga iButterfly?
Ivalvu yokujonga ibhabhathane, eyaziwa ngokuba yivalvu yokujonga idiski ezimbini, yivalvu engabuyiyo okanye ivalvu yendlela enye ethintela ukubuya kwamanzi kwimibhobho. Ngokungafaniyo neevalvu zebhabhathane, isebenza ngokuzenzekelayo ngaphandle kokusebenza kwangaphandle.
2.1 Umgaqo Wokusebenza
Ukuhamba phambili kutyhala idiski ivuleke, yoyisa uxinzelelo lwentwasahlobo. Xa ukuhamba kuyeka okanye kubuya umva, intwasahlobo iyayivala ngokukhawuleza idiski, idale isitywino esiqinileyo ukuthintela ukubuya kwamanzi. Olu sebenzi oluzenzekelayo aludingi kungenelela komntu.
2.2 Izicelo Eziqhelekileyo
- Imigca yokukhupha iipompo
- Iinkqubo zeCompressor
- Amaqonga oLwandle noLwandlekazi
- Ulawulo lwamanzi amdaka
3. Umahluko oPhambili phakathi kweeValve zeButterfly kunye neeValve zeButterfly Check
Nangona zombini zisebenzisa indlela yediski, usetyenziso lwazo oluphambili lwahlukile. Nantsi intelekelelo ecaleni kwelinye:
| Umbono | Ivalvu yebhabhathane | Ivalvu yokujonga ibhabhathane |
| Umsebenzi oPhambili | Ulawulo lokuhamba kwamanzi kunye nokwahlulwa | Ukuthintela ukubuyela umva |
| Umsebenzi | Ukujikeleza ngesandla okanye okuqhutywa yinkqubo | Okuzenzakalelayo (ilayishwe entwasahlobo) |
| Uyilo lweDiski | Idiski enye kwi-shaft | Iipleyiti ezimbini ezineehinji kunye nezipringi |
| Isikhokelo sokuhamba komoya | Icala eliya kwicala elibini (ngokutywinwa okufanelekileyo) | Icala elinye kuphela |
| Ufakelo | Iwafer, ilug, okanye iflanged | Iwafer, ilug, okanye iflanged |
Le theyibhile igxininisa izizathu zokukhetha enye kunenye: iivalvu zebhabhathane zokulawula, jonga iivalvu zokukhusela.
6. I-Water Hammer kunye nesantya sokuphendula
Ihamile yamanzi idla ngokwenzeka xa ukuhamba kolwelo kuyeka ngequbuliso, njengaxa ivalvu ivalwa ngokukhawuleza okanye ipompo ivalwa ngequbuliso. Oku kubangela ukuba amandla e-kinetic aguqulwe abe yi-pressure wave esasazeka ecaleni kombhobho. Olu xinzelelo lunokubangela ukugqabhuka kombhobho, ukukhululeka kweflange, okanye umonakalo wevalvu. Iivalvu zeButterfly kunye neevalvu zokujonga ibhabhathane zahlukile kubuchule bazo bokuphatha ihamile yamanzi ngenxa yoyilo kunye neendlela zokusebenza kwazo.
6.1 Iivalvu zebhabhathane kunye neHammer yamanzi
Isantya esivalwa ngaso ivalvu yebhabhathane sixhomekeke kwindlela esebenza ngayo (ngesandla, ngomoya, okanye ngombane). Ukuvala ngokukhawuleza kunokubangela ihamile yamanzi, ingakumbi kwiinkqubo ezinezinga eliphezulu lokuhamba kwamanzi okanye uxinzelelo oluphezulu. Oku kufuna ingqalelo ekhethekileyo kwiinkqubo zepompo.
Iivalvu zebhabhathane azenzelwanga ukuthintela ukubuya kwamanzi. Ukuba kukho umngcipheko wokubuyela kwamanzi kwinkqubo, ihamile yamanzi inokwenziwa mandundu kukubuyela kwamanzi kwakhona.
6.2 Iivalvu zokujonga iiButterfly kunye neHammer yamanzi
Iivalvu zokujonga ibhabhathane (iivalvu zokujonga iidiski ezimbini) zivaleka ngokuzenzekelayo kusetyenziswa iidiski ezimbini ezinespring-loaded ukuthintela ukubuya kwamanzi. Zenzelwe ukuphendula ngokukhawuleza kutshintsho kwicala lokuhamba kwamanzi nokuqinisekisa ukuvalwa kwangoko xa ulwelo luyema okanye lujika, lukhusela inkqubo ekonakaleni kokubuya kwamanzi. Nangona kunjalo, olu kuvalwa ngokukhawuleza lunokubangela ihamile yamanzi.
7. Imibuzo Ebuzwa Rhoqo
Ndingawuhlula njani ngokukhawuleza phakathi kwevalvu yebhabhathane kunye nevalvu yokujonga?
Iivalvu zebhabhathane zinezixhobo zokulawula umbane, ngelixa iivalvu zokujonga umbane zingenazo.
Ngaba ivalvu yebhabhathane ingasetyenziswa njengevalvu yokujonga?
Hayi, kuba ayinayo indlela yokuvala ezenzekelayo. Okuchasene noko kuyinyaniso.
Zifuna ukulungiswa njani ezi valve?
Iivalvu zebhabhathanekufuneka ihlolwe rhoqo isihlalo;iivalvu zokujongakufuneka ihlolwe rhoqo emva kweenyanga ezi-6-12.
