Njengomvelisi ophambili weevalvu ezikumgangatho ophezulu, iZFA ihlala ifumana imibuzo malunga nomahluko phakathi kweentlobo ezahlukeneyo zevalve. Umbuzo oqhelekileyo ngulo: Yintoni umahluko phakathi kwe-aivelufa butterflykunye aivelufa yokujonga ibhabhathane? Ngelixa babelana ngamagama afanayo kwaye bobabini basebenzisa uyilo lohlobo lwediski, imisebenzi yabo, imisebenzi, kunye nokusetyenziswa kwahluke kakhulu.
Esi sikhokelo siqwalasela ezi yantlukwano zingundoqo, sitsalela kubuchwephesha beZFA. Siza kugubungela iziseko-ezifana nengcaciso, uyilo, kunye nemigaqo yokusebenza. Nokuba uyinjineli, ingcali yokuthengwa kwempahla, okanye ingcali kwishishini, eli nqaku liza kukunceda wenze isigqibo esinolwazi.
1. Yintoni iValve yeButterfly?
Ivalve yebhabhathane yivalve ejikelezayo yekota esetyenziswa ikakhulu ukulawula ukuhamba okanye ukwahlula kwimibhobho. Ibonisa i-disc ejikelezayo malunga ne-axis ephakathi ukuvula okanye ukuvala indlela yokuhamba.
1.1 Isebenza njani iValve yebhabhathane
I-valve isebenza ngokujikeleza i-disc ye-90 degrees: ivule ngokupheleleyo, ivumela ukuhamba okungahambiyo, okanye ivaliwe, ivimba indlela yokuhamba. Ukujikeleza ngokuyinxenye kuvumela i-throttling, iyenze ilungele ukulawula ukuhamba.
1.2 Izicelo eziqhelekileyo
- Amaziko okucoca amanzi
- Iinkqubo zeHVAC
- UkuLungiswa kwemichiza
- Ishishini lokutya kunye nesiselo
2. Yintoni iButterfly Check Valve?
Ivalve yokukhangela ibhabhathane, ekwaziwa ngokuba yivalve yokujonga idiskhi ephindwe kabini, yivalve engabuyiyo okanye enye indlela ethintela ukubuya umva kwimibhobho. Ngokungafaniyo neevalvu zebhabhathane, isebenza ngokuzenzekelayo ngaphandle kokusebenza kwangaphandle.
2.1 UMmiselo wokuSebenza
Ukuqukuqela phambili kutyhala idiskhi ivuleke, yoyise ukuxinana kwentwasa hlobo. Xa ukuhamba kuyeka okanye ukubuyisela umva, intwasahlobo ivala ngokukhawuleza i-disc, idala itywina eliqinileyo ukukhusela umva. Lo msebenzi ozenzekelayo awufuni ungenelelo lomntu.
2.2 Izicelo eziqhelekileyo
- Imigca yokukhupha impompo
- Iinkqubo zeCompressor
- IiPlatform zaseLwandle kunye ne-Offshore
- Ulawulo lwamanzi amdaka
3. Umahluko oPhambili phakathi kweeValuvu zeButterfly kunye neButterfly Check Valves
Ngelixa bobabini besebenzisa indlela yediski, izicelo zabo eziphambili zahlukile. Nalu uthelekiso olusecaleni:
| Umba | Ivalve yebhabhathane | Butterfly Khangela iValve |
| Umsebenzi oPhambili | Ukulawulwa kokuhamba kunye nokwahlula | Uthintelo lokubuyela umva |
| Ukusebenza | Ujikelezo olwenziwa ngesandla okanye oluqhutywayo | Iyazenzekela (ilayishwe entwasahlobo) |
| Uyilo lweDiskhi | Idiski enye kwi-shaft | Iipleyiti ezimbini ezineehenjisi kunye nemithombo |
| Umkhombandlela wokuHamba | I-Bidirectional (ngokutywinwa ngokufanelekileyo) | Unidirectional kuphela |
| Ukuhlohla | I-Wafer, i-lug, okanye i-flanged | I-Wafer, i-lug, okanye i-flanged |
Le theyibhile igxininisa izizathu zokukhetha enye ngaphezu kwenye: iivalve zebhabhathane zokulawula, iivalve zokukhangela ukukhusela.
6. Isando samanzi kunye nesantya sokuphendula
Ihamile yamanzi ngokuqhelekileyo iyenzeka xa ukuhamba kwamanzi kuyekwa ngokukhawuleza, njengaxa ivalve ivalwe ngokukhawuleza okanye impompo ivalwe ngokukhawuleza. Oku kubangela ukuba amandla e-kinetic aguqulwe abe yi-pressure wave esasaza ecaleni kombhobho. Olu sothuko lunokubangela ukugqabhuka kombhobho, ukukhululeka kweflange, okanye ukonakala kwevalvu. Iivalve zebhabhathane kunye neevalvu zokukhangela ibhabhathane ziyahluka kubuchule bazo bokuphatha ihamile yamanzi ngenxa yoyilo kunye neendlela zokusebenza.
6.1 Iivalvu zeButterfly kunye neHammer yaManzi
Isantya evalwa ngaso ivalve yebhabhathane sixhomekeke kwindlela elisebenza ngayo (i-manual, i-pneumatic, okanye i-electric). Ukuvala ngokukhawuleza kunokubangela isando samanzi, ngakumbi kwiinkqubo ezinezinga eliphezulu lokuhamba okanye uxinzelelo oluphezulu. Oku kufuna ingqalelo ekhethekileyo kwiinkqubo zempompo.
Iivalve zebhabhathane azenzelwanga ukuthintela ukuphuma ngasemva. Ukuba kukho umngcipheko wokubuyela umva kwinkqubo, isando samanzi sinokugqithiswa ngokubuyela umva.
6.2 Iivalvu zeButterfly Check neHammer yaManzi
Iivalvu zokujonga ibhabhathane (iivalvu zokujonga idiskhi ephindwe kabini) zivale ngokuzenzekelayo zisebenzisa iidiski ezimbini ezilayishwe entwasahlobo ukuthintela ukubuya umva. Zenzelwe ukuphendula ngokukhawuleza kwiinguqu kwindlela yokuhamba kunye nokuqinisekisa ukuvala ngokukhawuleza xa umbane uyeka okanye ujika, ukukhusela inkqubo kumonakalo wokubuyela umva. Nangona kunjalo, oku kuvalwa ngokukhawuleza kunokubangela ihamile yamanzi.
7. FAQ
Ndinokwahlula njani ngokukhawuleza phakathi kwevalve yebhabhathane kunye nevalve yokukhangela?
Iivalve zebhabhathane zinee-actuators, ngelixa iivalve zetshekhi zingenazo.
Ngaba ivalve yebhabhathane ingasetyenziswa njengevalve yokutshekisha?
Hayi, kuba ayinayo indlela yokuvala ezenzekelayo. Okuchaseneyo nako kuyinyaniso.
Ingaba ezi zivalo zifuna ulondolozo olunjani?
Iivalve zebhabhathanezifuna ukuhlolwa kwesihlalo rhoqo;khangela iivalvezifuna ukuhlolwa kwentwasahlobo rhoqo emva kweenyanga ezi-6-12.
