Kungani ukhetha ama-ball valve

1. Kulula ukuyisebenzisa futhi kulula ukuyivula nokuyivala.

Mane nje ujike isibambo noma i-actuator ngama-degree angu-90 (ukujika kwekota) ukuze ushintshe kusuka ekuvulekeni ngokuphelele uye ekuvalekeni ngokuphelele noma ngokuphambene nalokho. Lokhu kwenza ukusebenza kokuvula nokuvala kube lula kakhulu, futhi kufaneleka kakhulu ezimweni lapho kudingeka khona ukuvulwa nokuvalwa njalo noma ukuvalwa okuphuthumayo.

2. Ukusebenza okuhle kakhulu kokuvala

Uma ivaliwe ngokuphelele, ibhola lithintana ngokuqinile nesihlalo sevalvu, linikeze uphawu oluqondile (lungavala kungakhathalekile ukuthi i-medium iphuma kuluphi uhlangothi), livimbele ngempumelelo ukuvuza. Amavalvu ebhola asezingeni eliphezulu (njengalawo anezivikelo ezithambile) angafinyelela ukuvuza okungekho, ahlangabezane nezindinganiso eziqinile zokuvikelwa kwemvelo kanye nokuphepha.

3. Inokumelana nokugeleza okuphansi kakhulu kanye nomthamo wokugeleza oqinile.

Uma ivalvu ivuliwe ngokugcwele, ububanzi besiteshi ngaphakathi komzimba wevalvu buvame ukufana nobubanzi bangaphakathi bepayipi (okubizwa ngokuthi ivalvu yebhola egcwele), futhi isiteshi sebhola sisesimweni esiqondile. Lokhu kwenza i-medium idlule cishe ngaphandle kokuvinjelwa, ine-coefficient ephansi kakhulu yokumelana nokugeleza, okunciphisa ukulahleka kwengcindezi kanye nokonga ukusetshenziswa kwamandla kwamaphampu noma ama-compressor.

4. Isakhiwo esincane kanye nomthamo omncane

Uma kuqhathaniswa nama-valve esango noma ama-valve e-globe anobubanzi obufanayo, ama-valve ebhola anesakhiwo esilula, esincane futhi anesisindo esilula. Lokhu kusindisa isikhala sokufaka futhi kuzuzisa kakhulu izinhlelo zamapayipi ezinesikhala esilinganiselwe.

5. Uhla olubanzi lwezicelo kanye nokuguquguquka okunamandla

• Ukuzivumelanisa nezimo kwemidiya:Ingasetshenziswa ezintweni ezahlukahlukene ezifana namanzi, uwoyela, igesi, umusi, amakhemikhali agqwalisayo (izinto ezihambisanayo kanye nezisimbozo kudingeka zikhethwe).
• Uhla lokucindezela kanye nokushisa:Kusukela ku-vacuum kuya ku-high pressure (kufika ku-Bar engamakhulu amaningana), kusukela ekushiseni okuphansi kuya ekushiseni okuphakathi-phezulu (kuye ngokuthi yini evalwe ngayo, izivalo ezithambile ngokuvamile zi-≤ 200℃, kuyilapho izivalo eziqinile zingafinyelela amazinga okushisa aphezulu). Isebenza kuzo zonke lezi zigaba.
• Ububanzi bebanga:Kusukela kumavalvu amancane ezinsimbi (amamilimitha ambalwa) kuya kumavalvu amakhulu epayipi (ngaphezu kwemitha eli-1), kunemikhiqizo evuthiwe etholakalayo yabo bonke osayizi.
