Yini auvemvane valve?
Ivalve yovemvane ibizwa ngokuthi i-butterfly valve ngoba umumo wayo ufana novemvane.I-actuator izungezisa i-valve plate ngo-0-90 degrees ukuze ivule futhi ivale i-valve, noma ukulungisa kafushane izinga lokugeleza.
Yini ai-valve yebhola?
Amavalvu ebhola nawo asetshenziswa kumapayipi ukulawula amavalvu alawula ukugeleza koketshezi.Ngokuvamile basebenzisa i-sphere enembobo ukulawula ukugeleza koketshezi, olungadlula noma luvinjwe njengoba i-sphere iphenduka.
Njengezingxenye zokulawula uketshezi, amavalvu ovemvane namavalvu ebhola angasetshenziswa kokubili ukuxhuma nokusika okuphakathi epayipini.Uyini umehluko, izinzuzo kanye nokubi?Ngezansi siyayihlaziya kusukela esakhiweni, ububanzi bokusetshenziswa, kanye nezidingo zokutywinwa.
1. Isakhiwo nesimiso
- Ingxenye yokuvula neyokuvala ye-valve uvemvane, ipuleti le-valve, njengoba negama lisho, iyisiqephu esimise okwepuleti esinogqinsi oluthile, kuyilapho ingxenye yokuvula nokuvala ye-valve yebhola iyindilinga.
- Ama-valve e-butterfly alula futhi anesakhiwo esihlangene, ngakho-ke anesisindo esincane;kuyilapho ama-valve ebhola enomzimba omude futhi adinga indawo enkulu lapho evula futhi evala.Zivame ukuba zinkulu futhi zibe nzima.
- Lapho i-valve yovemvane ivuleke ngokugcwele, ipuleti levalvu lizungeza liqondane lapho ligeleza khona, livumela ukugeleza okungakhawulelwe.Lapho i-valve ye-butterfly ivaliwe, ipuleti ye-valve i-perpendicular isiqondiso sokugeleza okuphakathi, ngaleyo ndlela ivimbele ngokuphelele ukugeleza.
- Uma i-valve yebhola egcwele ngokugcwele ivuleke ngokugcwele, izimbobo zihambisana nepayipi, zivumela uketshezi ukuba ludlule.Futhi lapho ivaliwe, ibhola lizungeza ama-degree angu-90, livimbele ngokuphelele ukugeleza.I-valve yebhola egcwele inciphisa ukwehla kwengcindezi.
2. Ububanzi besicelo
- Ama-valve ovemvane angasetshenziswa kuphela ukugeleza kwezindlela ezimbili;ama-valve ebhola angasetshenziswa futhi njengama-diverter wezindlela ezintathu ngaphezu kokugeleza kwezindlela ezimbili.
- Ama-valve ovemvane alungele ukulawula/ukuvala imidiya yamapayipi anomfutho ophansi;ama-valve ebhola angasetshenziselwa ukulawula ukugeleza okunembile ekushiseni okuphezulu nezimo zengcindezi.
- Ama-valve e-Butterfly asetshenziswa kakhulu ekuhlanzeni indle, ukucubungula ukudla, izinhlelo ze-HVAC, izinhlelo zokupholisa umoya nezinye izinkambu;ama-valve ebhola asetshenziswa kakhulu ku-petroleum, igesi yemvelo, imboni yamakhemikhali, i-metallurgy, amandla kagesi nezinye izimboni.
3. Ukubekwa uphawu
- Amavalvu uvemvane avala ngokuthambile ancike ezihlalweni zamavalvu ezinwebekayo njengerabha noma i-PTFE ukwenza isivalo ngokucindezela eduze kwepuleti levalvu.Kunethuba elithile lokuthi lolu phawu luzowohloka ngokuhamba kwesikhathi, okungase kubangele ukuvuza.
- Amavalvu ebhola ngokuvamile afaka izigxivizo zensimbi-kuya-zensimbi noma ezithambile ezinikeza uphawu oluthembekile ngisho nangemva kokusetshenziswa isikhathi eside.
Kafushane, ama-valve ovemvane nama-valve ebhola ngayinye inezinzuzo zayo kanye nokubi, futhi iyiphi i-valve okufanele ikhethwe incike ezimweni ezithile zohlelo lokusebenza kanye nezidingo.
I-ZFA Valve Company iyifekthri egxile ekukhiqizeni ama-valve ovemvane ahlukahlukene.Uma unemibuzo, sicela ukhululeke ukuxhumana nathi.
