Njengomkhiqizi oholayo wama-valve ekhwalithi ephezulu, i-ZFA ivame ukuthola imibuzo mayelana nomehluko phakathi kwezinhlobo zama-valve ahlukahlukene. Umbuzo ojwayelekile uthi: Uyini umehluko phakathi kwe-auvemvane valvekanye ai-valve yokuhlola uvemvane? Ngenkathi babelana ngamagama afanayo futhi bobabili basebenzisa idizayini yohlobo lwediski, imisebenzi yabo, ukusebenza, kanye nezinhlelo zokusebenza kuhluke kakhulu.
Ugwalo lolu ludingisisa umehluko oqakathekileyo lo, lusebenzisa ubungcitshi beZFA. Sizofaka izinto eziyisisekelo—ezifana nencazelo, idizayini, nezimiso zokusebenza. Kungakhathaliseki ukuthi ungunjiniyela, uchwepheshe wokuthengwa kwempahla, noma uchwepheshe wemboni, lesi sihloko sizokusiza wenze isinqumo unolwazi.
1. Iyini i-Butterfly Valve?
I-butterfly valve iyivalvu ejikelezayo yekota esetshenziselwa ngokuyinhloko ukulawula ukugeleza noma ukuhlukaniswa kwamapayipi. Ihlanganisa idiski ezungeza i-eksisi emaphakathi ukuze ivule noma ivale indlela yokugeleza.
1.1 Isebenza kanjani i-Butterfly Valve
I-valve isebenza ngokuzungeza i-disc 90 degrees: ivule ngokugcwele, ivumela ukugeleza okungavinjelwe, noma ivaliwe, ivimbela indlela yokugeleza. Ukuzungezisa kancane kuvumela ukunyakazisa, okuyenza ifaneleke ukulawula ukugeleza.
1.2 Izicelo Ezijwayelekile
- Izitshalo Zokuhlanza Amanzi
- HVAC Systems
- Chemical Processing
- Imboni Yokudla Neziphuzo
2. Iyini i-Butterfly Check Valve?
I-valve yokuhlola uvemvane, eyaziwa nangokuthi i-valve yokuhlola i-double disc, iyivalvu engabuyi noma indlela eyodwa evimbela ukugeleza emuva kumapayipi. Ngokungafani nama-valve ovemvane, isebenza ngokuzenzakalelayo ngaphandle kokusebenza kwangaphandle.
2.1 Umgomo Wokusebenza
Ukugeleza phambili kuphusha idiski livuleke, kunqobe ukushuba kwesimo sasentwasahlobo. Lapho ukugeleza kuma noma kuhlehla, isiphethu sivala ngokushesha i-disc, senze uphawu oluqinile ukuze kuvinjelwe ukugeleza emuva. Lokhu kusebenza okuzenzakalelayo akudingi ukungenelela komuntu.
2.2 Izicelo Ezijwayelekile
- Imigqa Yokukhipha Iphampu
- Compressor Systems
- Izinkundla Zasolwandle Nasolwandle
- Ukuphathwa kwamanzi angcolile
3. Umehluko Obalulekile Phakathi Kwamavalvu Ovemvane namaVave Okuhlola I-Butterfly
Ngenkathi bobabili besebenzisa indlela yediski, izinhlelo zabo zokusebenza eziyinhloko zihlukile. Nasi isiqhathaniso sezinhlangothi:
| Isici | I-Butterfly Valve | I-Butterfly Check Valve |
| Umsebenzi Oyinhloko | Ukulawulwa kokugeleza kanye nokuhlukaniswa | Ukuvimbela ukubuyela emuva |
| Ukusebenza | Ukuzungezisa okwenziwa ngesandla noma okucushiwe | Okuzenzakalelayo (kulayishwa intwasahlobo) |
| Idizayini yeDiskhi | I-Single disc ku-shaft | Amapuleti amabili anamahinge neziphethu |
| Flow Direction | I-Bidirectional (ngokuvalwa kahle) | I-unidirectional kuphela |
| Ukufakwa | I-wafer, i-lug, noma i-flanged | I-wafer, i-lug, noma i-flanged |
Leli thebula liqokomisa izizathu zokukhetha elinye phezu kwelinye: amavalvu ovemvane okulawula, hlola amavalvu ukuze avikeleke.
6. Isando samanzi kanye nesivinini sokuphendula
Isando samanzi ngokuvamile senzeka lapho ukugeleza koketshezi kumiswa ngokuzumayo, njengalapho ivalvu ivalwa ngokushesha noma iphampu ivaleka kungazelelwe. Lokhu kubangela ukuthi amandla e-kinetic aguqulwe abe igagasi lokucindezela elisakazeka eduze kwepayipi. Lokhu kushaqeka kungabangela ukuqhuma kwamapayipi, ukuxega kwe-flange, noma ukulimala kwevalvu. Ama-valve ovemvane nama-valve okuhlola uvemvane ayahluka ekhonweni lawo lokuphatha isando samanzi ngenxa yokuklama kwawo nezindlela zokusebenza.
6.1 Amavavu Ovemvane Nesando Samanzi
Isivinini lapho i-valve uvemvane ivala khona sincike endleleni esebenza ngayo (ngesandla, esomoya, noma ngogesi). Ukuvala ngokushesha kungabangela isando samanzi, ikakhulukazi kumasistimu anamazinga aphezulu okugeleza noma izingcindezi eziphezulu. Lokhu kudinga ukunakwa okukhethekile ezinhlelweni zamaphampu.
Ama-valve ovemvane awaklanyelwe ukuvimbela ukugeleza emuva. Uma kukhona ubungozi bokubuyela emuva ohlelweni, isando samanzi singabhebhetheka ngokugeleza emuva.
6.2 Amavavu Okuhlola Uvemvane Nesando Samanzi
Ama-valve okuhlola i-Butterfly (ama-valve okuhlola ama-double-disc) avala ngokuzenzakalelayo kusetshenziswa ama-disc alayishwe entwasahlobo ukuze avimbele ukubuyela emuva. Zenzelwe ukuphendula ngokushesha ezinguqukweni zokugeleza kanye nokuqinisekisa ukuvala ngokushesha lapho uketshezi luma noma luhlehla, kuvikela isistimu emonakalweni wokubuyela emuva. Nokho, lokhu kuvaleka ngokushesha kungabangela isando samanzi.
7. Imibuzo Evame Ukubuzwa
Ngingakwazi kanjani ukuhlukanisa ngokushesha phakathi kwevalve uvemvane nevalve yokuhlola?
Ama-valve ovemvane anama-actuator, kuyilapho ama-valve okuhlola engenawo.
Ingabe i-valve uvemvane ingasetshenziswa njengevalufu yokuhlola?
Cha, ngoba ayinayo indlela yokuvala ezenzakalelayo. Okuphambene nakho kuyiqiniso.
Lawa ma-valve adinga kunakekelwa ini?
Ama-valve e-Butterflyzidinga ukuhlolwa kwesihlalo njalo;hlola ama-valvezidinga ukuhlolwa kwentwasahlobo njalo ezinyangeni ezi-6-12.
