Njengomkhiqizi ohamba phambili wama-valve asezingeni eliphezulu, i-ZFA ivame ukuthola imibuzo mayelana nomehluko phakathi kwezinhlobo ezahlukene zama-valve. Umbuzo ovamile uthi: Uyini umehluko phakathi kwe-ivalvu yebhabhathanekanyeivalvu yokuhlola uvemvaneNakuba zabelana ngamagama afanayo futhi zombili zisebenzisa umklamo wohlobo lwediski, imisebenzi yazo, ukusebenza, kanye nezinhlelo zokusebenza zihlukile kakhulu.
Lo mhlahlandlela uhlola lo mehluko obalulekile, usebenzisa ubuchwepheshe be-ZFA. Sizohlanganisa izinto eziyisisekelo—njengencazelo, ukuklama, kanye nezimiso zokusebenza. Kungakhathaliseki ukuthi ungunjiniyela, uchwepheshe wokuthenga, noma uchwepheshe wemboni, lesi sihloko sizokusiza ukuthi wenze isinqumo esinolwazi.
1. Iyini i-Butterfly Valve?
I-butterfly valve iyi-valve ejikelezayo ejikelezayo esetshenziswa kakhulu ukulawula ukugeleza noma ukuhlukanisa amapayipi. Ine-disc ejikeleza i-axis ephakathi ukuvula noma ukuvala indlela yokugeleza.
1.1 Indlela I-Butterfly Valve Esebenza Ngayo
Ivalvu isebenza ngokujikeleza idiski ngamadigri angu-90: ivuleke ngokuphelele, ivumela ukugeleza okungavinjelwe, noma ivalwe, ivimbe indlela yokugeleza. Ukujikeleza okuyingxenye kuvumela ukugoba, okwenza ifanelekele ukulawula ukugeleza.
1.2 Izicelo Ezivamile
- Izitshalo Zokwelapha Amanzi
- Izinhlelo ze-HVAC
- Ukucubungula Amakhemikhali
- Imboni Yokudla Neziphuzo
2. Iyini i-Butterfly Check Valve?
Ivalvu yokuhlola i-butterfly, eyaziwa nangokuthi ivalvu yokuhlola i-double-disc, iyivalvu engabuyi noma ivalvu yendlela eyodwa evimbela ukubuyela emuva kwamapayipi. Ngokungafani namavalvu e-butterfly, isebenza ngokuzenzakalelayo ngaphandle kokusebenza kwangaphandle.
2.1 Isimiso Sokusebenza
Ukugeleza phambili kusunduza idiski livuleke, kunqobe ukucindezeleka kwentwasahlobo. Lapho ukugeleza kuma noma kubuyela emuva, intwasahlobo ivala idiski ngokushesha, idale ukuvala okuqinile ukuvimbela ukugeleza emuva. Lokhu kusebenza okuzenzakalelayo akudingi ukungenelela komuntu.
2.2 Izicelo Ezivamile
- Imigqa Yokukhipha Iphampu
- Izinhlelo zeCompressor
- Amapulatifomu asemanzini nawasogwini
- Ukuphathwa Kwamanzi Angcolile
3. Umehluko Obalulekile Phakathi Kwama-Butterfly Valve nama-Butterfly Check Valve
Nakuba zombili zisebenzisa indlela yediski, izinhlelo zazo eziyinhloko zihlukile. Nasi ukuqhathanisa okuseceleni:
| Isici | I-Butterfly Valve | I-valve yokuhlola ubhabhathane |
| Umsebenzi Oyinhloko | Ukulawulwa kokugeleza kanye nokuhlukaniswa | Ukuvimbela ukugeleza emuva |
| Ukusebenza | Ukuzungezisa ngesandla noma okuqhutshwayo | Okuzenzakalelayo (okulayishwe entwasahlobo) |
| Umklamo weDiski | Idiski eyodwa kushaft | Amapuleti amabili anamahinji neziphethu |
| Isiqondiso Sokugeleza | Izinhlangothi ezimbili (ngokuvala kahle) | Isiqondiso esisodwa kuphela |
| Ukufakwa | I-wafer, i-lug, noma i-flanged | I-wafer, i-lug, noma i-flanged |
Leli thebula liqokomisa izizathu zokukhetha elilodwa kunelinye: ama-butterfly valve okulawula, hlola ama-valve okuvikela.
6. Isando Samanzi kanye Nesivinini Sokuphendula
I-Water hammer ivame ukwenzeka lapho ukugeleza koketshezi kunqamuka ngokuzumayo, njengalapho i-valve ivalwa ngokushesha noma i-pump ivalwa ngokuzumayo. Lokhu kubangela ukuthi amandla e-kinetic aguqulwe abe yi-pressure wave esakazeka eceleni kwepayipi. Lokhu kushaqeka kungabangela ukuqhuma kwepayipi, ukukhululeka kwe-flange, noma ukulimala kwe-valve. Ama-Butterfly valve nama-butterfly check valve ahlukile ekhonweni lawo lokuphatha i-water hammer ngenxa yokwakheka kwawo kanye nezindlela zokusebenza.
6.1 Amavalvu Ovemvane Nesando Samanzi
Isivinini lapho ivalvu yebhabhathane ivala khona sincike endleleni yokusebenza kwayo (ngesandla, ngomoya, noma ngogesi). Ukuvala okusheshayo kungabangela isando samanzi, ikakhulukazi ezinhlelweni ezinezinga eliphezulu lokugeleza noma ukucindezela okuphezulu. Lokhu kudinga ukunakwa okukhethekile ezinhlelweni zephampu.
Amavalvu e-Butterfly awaklanyelwe ukuvimbela ukugeleza emuva. Uma kunengozi yokugeleza emuva ohlelweni, isando samanzi singaba sibi kakhulu ngokugeleza emuva.
6.2 Amavalvu Okuhlola Uvemvane kanye Nesando Samanzi
Ama-valve okuhlola ama-butterfly (ama-valve okuhlola ama-double-disc) avala ngokuzenzakalelayo kusetshenziswa ama-disc amabili agcwele intwasahlobo ukuvimbela ukugeleza emuva. Aklanyelwe ukusabela ngokushesha ezinguqukweni zendlela yokugeleza futhi aqinisekise ukuvalwa okusheshayo lapho uketshezi luyeka noma lubuyela emuva, okuvikela uhlelo ekulimaleni kokugeleza emuva. Kodwa-ke, lokhu kuvalwa okusheshayo kungabangela i-water hammer.
7. Imibuzo Evame Ukubuzwa
Ngingawuhlukanisa kanjani ngokushesha phakathi kwevalvu yebhabhathane nevalvu yokuhlola?
Amavalvu ebhabhathane anama-actuator, kuyilapho amavalvu okuhlola engenawo.
Ingabe ivalvu yebhabhathane ingasetshenziswa njengevalvu yokuhlola?
Cha, ngoba ayinayo indlela yokuvala ezenzakalelayo. Okuphambene nalokho nakho kuyiqiniso.
Yikuphi ukunakekelwa okudingekayo ngala ma-valve?
Amavalvu ebhabhathanedinga ukuhlolwa njalo kwesihlalo;ama-valve okuhlolazidinga ukuhlolwa kwentwasahlobo njalo ezinyangeni eziyi-6-12.
