Paunenge uchisarudza iyo vharafu yakakodzera yeindasitiri, yekurima, kana yekutengesa pombi masisitimu, kunzwisisa mutsauko uripolug butterfly mavharuvhuuyekaviri flange butterfly mavharuvhukwakakosha. Ose mavharuvhu anoshandiswa zvakanyanya mukurapa kwemvura, kugadzirwa kwemakemikari, HVAC, uye maindasitiri emafuta negasi nekuda kwekugadzira kwawo compact, mutengo-unoshanda, uye kuyerera kuyerera kwekutonga. Nekudaro, dhizaini yavo, nzira dzekuisa, uye mamiriro ekushandisa anosiyana, zvichiita kuti imwe neimwe ikwane kune chaiwo mamiriro. Ichi chinyorwa chinoongorora misiyano yakakosha, zvakanakira, zvazvakaipira, uye mashandisirwo erug uye maviri flange butterfly mavharuvhu kutungamira maitiro ako ekuita sarudzo.
1. Lug Butterfly Valve: Dhizaini uye Zvimiro
Lug butterfly mavharuvhu anoratidzirwa neakaiswa shinda, kana "malugi," pamutumbi wevharuvhu, izvo zvinobvumira kusungirira kwakananga kune pombi flanges. Iyi dhizaini inoshandisa maseti maviri emabhaudhi akazvimirira asina nzungu, semabhaudhi akananga mumakumbo. Kurongeka kwakadaro kwakanakira magumo-e-mutsara zvikumbiro, uko rimwe divi repombi rinogona kubviswa pasina kukanganisa rimwe.
Zvinhu Zvikuru zveLug Butterfly Valves
-Threaded Lugs: Lugs anopa akasimba ekumisikidza mapoinzi, achigonesa vharafu kuti ichengetedzwe yakazvimirira kune yega pombi flange.
- Compact Dhizaini: Yakareruka uye ipfupi pakureba, lug mavharuvhu anochengetedza nzvimbo, akanakira masisitimu ane kamuri shoma.
-Kuyerera kweBidirectional: Mavharuvhu akapfava-akavharirwa anotsigira kuyerera munzira ipi neipi, achipa kuita zvakasiyana.
- Easy Maintenance: Iyo lug kumisikidzwa inobvumira rimwe divi repombi kuti ribviswe kuti rigadziriswe pasina kukanganisa rimwe.
- Pressure Rating: Kazhinji inokodzera yakaderera kusvika yepakati-kudzvanywa maapplication, kunyangwe kudzvanywa ratings kunogona kuderera mukupera-kwe-mutsara sevhisi.
- Material Versatility: Inowanikwa mumidziyo senge ductile iron, WCB, kana simbi isina tsvina, ine zvigaro zvingasarudzwa seEPDM kana PTFE yemakemikari kuramba.
2. Double Flange Butterfly Valve: Dhizaini uye Zvimiro
Mavharuvhu eshavishavi maviri eflange ane maflange akabatanidzwa pamativi ese emuviri wevharuvhu, akabhaurirwa zvakanangana nepombi flanges. Iyi dhizaini inovimbisa kubatanidza-kuvuza-chiratidzo, ichiita kuti ive yakakodzera kune yakakwirira-kumanikidza uye yakakura-dhayamita maapplication. Kuvakwa kwayo kwakasimba kunoshingirira masimba makuru.
Zvinhu Zvikuru zveDouble Flange Butterfly Valves
- Yakabatanidzwa Flanges: Flanges pamativi ese ari maviri anobatana kune pombi flanges kuburikidza nemabhoti, kuve nechokwadi chakachengeteka kukwana.
- Yakasimba Chimiro: Yakagadzirwa kubva kune yakasimba zvinhu seWCB, ductile iron, kana simbi isina tsvina.
-Kuisa Chisimbiso Chepamusoro: Dhizaini yeFlange inovimbisa chisimbiso chakasimba, ichidzikisa njodzi dzekuvuza mumashandisirwo akakosha.
-Kuyerera kweBidirectional: Kufanana nemavharuvhu egugi, mavharuvhu maviri eflange anotsigira kuyerera mumativi ese.
- Yakakura Diameter: Inotora madhayamita akakura achienzaniswa nemavharuvhu.
3. Lug Butterfly Valve vs. Double Flange Butterfly Valve
Kuti uite sarudzo ine ruzivo, zvakakosha kunzwisisa misiyano yakakosha pakati pelug nekaviri flange butterfly valves. Pazasi kuenzanisa kwakadzama kwezvinhu zvakakosha:
3.1 Zvakafanana Zvimiro
-Kuiswa Kuchinjika: Ose anobvumira rimwe divi repombi kuti ribviswe pasina kukanganisa rimwe, rakanakira masisitimu anoda kugara achigadziriswa kana kuparadzaniswa kwechikamu.
- Mutengo Uchienzaniswa neWafer Mavharuvhu: Nekuda kwemalugs akarukwa kana maviri maflange, ese ari maviri anodhura kupfuura mavharuvhu.
- Hunhu hwakagovaniswa:
- Bidirectional Flow Tsigiro: Mavharuvhu ese ari maviri anogadzika kuyerera mune chero nzira, akakodzera masisitimu ane akasiyana emvura nzira.
- Material Variety: Zvese zvinogona kugadzirwa kubva kuzvinhu zvakafanana senge kabhoni simbi, ductile iron, kana Stainless simbi, ine zvigaro zvingasarudzwa (semuenzaniso, EPDM kana PTFE) zvakagadzirirwa kumvura yakaita semvura, makemikari, kana magasi.
3.2 Misiyano Yakakosha
3.2.1 Kuisa Mechanism
- Lug Butterfly Valve: Inoshandisa mabhaudhi emusoro-mumwe kubatanidza kune pombi flanges. Iwo tambo dzakarukwa dzinobvumira seti mbiri dzemabhaudhi kuchengetedza vharafu yakazvimirira isina nzungu, ichitsigira nyore kupera-kwe-mutsara sevhisi uye kugadzirisa.
-Kaviri Flange Butterfly Valve: Mamiriro akasanganiswa maflange pamativi ese, anoda kurongeka nepombi flanges uye bolting. Izvi zvinovimbisa kubatana kwakasimba asi kunonetsa kuchengetedza.
3.2.2 Installation Flexibility
- Lug Butterfly Valve: Inopa kuchinjika kukuru, sezvo rimwe divi rinogona kubviswa pasina kukanganisa rimwe, rakanakira masisitimu anoda kugara achigadziriswa kana kutsiviwa.
-Kaviri Flange Butterfly Valve: Inoda kurongeka uye bhaudhi pamativi ese, kugadzira kuisirwa uye kubvisa kunotora nguva. Inopa kushomeka kwekugadzirisa kuchinjika asi yakachengeteka yekubatanidza.
3.2.3 Anoshanda Diameters
- Lug Butterfly Valve: Kazhinji kubva kuDN50 kusvika kuDN600.Single flange mavharuvhuinogona kuva imwe nzira yenzvimbo-yakamanikidzwa masisitimu.
-Kaviri Flange Butterfly Valve: Kubva kuDN50 kusvika kuDN1800. Kune madhayamita akakura, mhinduro dzetsika dzinowanikwa pakukumbira.
3.2.4 Mutengo uye Huremu
- Lug Butterfly Valve: Yakawedzera kudhura-inoshanda nekuda kwekureruka kwayo dhizaini, kuderedza mari yekuisa.
-Kaviri Flange Butterfly Valve: Inorema uye inodhura zvakanyanya nekuda kweakasanganiswa maflange uye zvimwe zvinhu. Hombe-diameter mbiri flange mavharuvhu angada imwe rutsigiro nekuda kwehuremu hwawo.
3.2.5 Maintenance uye Disassembly
- Lug Butterfly Valve: Zviri nyore kuparadzanisa uye kuchengetedza, sezvo rimwe divi rinogona kubviswa pasina kukanganisa rimwe.
-Kaviri Flange Butterfly Valve: Yakawedzera kushanda-yakanyanya kuparadzanisa nekuda kweakawanda mabhaudhi uye chaiyo kurongeka zvinodiwa.
4. Mhedziso
Chisarudzo pakati pechinyoro-chakavharwalug butterfly valveuye akaviri flange butterfly vharafuzvinoenderana nezvido zvehurongwa hwako. Lug butterfly mavharuvhu anokunda mumaapplication anoda kugara achigadziriswa uye kuisirwa compact. Mavharuvhu eshavishavi maviri eflange, ane chisimbiso chawo chakasimba, anokodzera zvirinani mapaipi makuru-dhayamita uye maapplication akakosha. Nekuongorora zvinhu zvakaita sekumanikidza, kuchengetedza, nzvimbo, uye bhajeti, unogona kusarudza vharafu inokwirisa mashandiro uye mutengo-kubudirira.
