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 kusakhiwo, ububanzi bokusebenza, kanye nezidingo zokuvala uphawu.
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 uma 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.
