I. Izimiso ZokukhethaAmavalvu Ovemvane
1. Ukukhetha uhlobo lwesakhiwo
Ivalvu yebhabhathane ephakathi (uhlobo lomugqa ophakathi):Isiqu se-valve kanye nediski ye-butterfly kuyafana phakathi nendawo, kunesakhiwo esilula kanye nezindleko eziphansi. Ukuvalwa kuncike ekuvalekeni okuthambile kwerabha. Kufanelekile ngezikhathi lapho izinga lokushisa nengcindezi evamile ijwayelekile futhi kungekho zidingo eziqinile.
Ivalvu eyodwa yebhabhathane engavamile:Isiqu sevalvu sibekwe eceleni kusukela enkabeni yediski yebhabhathane, kunciphisa ukungqubuzana phakathi kwezindawo zokuvala ngesikhathi sokusebenza futhi kwandise isikhathi senkonzo. Ilungele ukusetshenziswa kokucindezela okuphakathi nokuphansi okudinga ukuvulwa nokuvalwa njalo.
Ivalvu yebhabhathane ephindwe kabili (ivalvu yebhabhathane esebenza kahle kakhulu):Isiqu se-valve sisuselwe kokubili kudiski ye-butterfly kanye nesikhungo sokuvala, okuvumela ukusebenza ngaphandle kokungqubuzana. Ngokuvamile sinesivalo sensimbi noma esihlanganisiwe. Silungele imidiya yokushisa okuphezulu, yokucindezela okuphezulu, ebolile, noma yezinhlayiya.
Ivalvu yebhabhathane enezinhlangothi ezintathu:Uma ihlanganisa ukungafani okubili nepheya lokuvala eliyindilinga eligobile, ifinyelela ukungqubuzana okungenalutho kanye nokuvuza okungenalutho, ngokumelana nokushisa okuphezulu kanye nokucindezela okuphezulu. Ilungele izimo zokusebenza ezinzima (isb. umusi, uwoyela/igesi, imidiya yokushisa okuphezulu).
2. Ukukhetha imodi yedrayivu
Incwadi Yemiyalelo:ngezimo zokusebenza ezincane (DN≤200), ukucindezela okuphansi, noma okungajwayelekile.
I-Worm gear drive:Ifanele ukusetshenziswa kobubanzi obuphakathi kuya kobukhulu obudinga ukusebenza okulula noma ukulawulwa kokugeleza.
Omoya/Ugesi:Ukulawula kude, izinhlelo zokwenza izinto ngokuzenzakalela, noma izidingo zokuvala ngokushesha (isb., izinhlelo ze-alamu yomlilo, ukuvala okuphuthumayo).
3. Izinto zokuvala kanye nezinto zokwakha
Isiciko esithambile (irabha, i-PTFE, njll.): ukuvala okuhle, kodwa ukumelana nokushisa okulinganiselwe kanye nokucindezela (ngokuvamile ≤120°C, PN≤1.6MPa). Kufanelekela amanzi, umoya kanye nemidiya yokugqwala ebuthakathaka.
Izivikelo zensimbi (insimbi engagqwali, i-carbide eqinisiwe): Ukumelana nokushisa okuphezulu (kufika ku-600°C), umfutho ophezulu, kanye nokumelana nokuguguleka nokugqwala, kodwa ukusebenza kokuvala kuphansi kancane kunezivikelo ezithambile. Kufanelekela imidiya yokushisa ephezulu kwezensimbi, izitshalo zikagesi, kanye namakhemikhali kaphethroli.
Izinto zomzimba: Insimbi ehlanganisiwe, insimbi yekhabhoni, insimbi engagqwali, insimbi ye-alloy, noma ulwelwesi lwepulasitiki/irabha kuye ngokuthi insimbi igqwala kangakanani.
4. Uhla lokucindezela kanye nokushisa:
Amavalvu ebhabhathane avaliwe ngokuthambile ngokuvamile asetshenziselwa i-PN10~PN16, enamazinga okushisa angu-≤120°C. Amavalvu ebhabhathane avaliwe ngensimbi amathathu angafinyelela ngaphezu kwe-PN100, enamazinga okushisa angu-≥600°C.
5. Izici Zethrafikhi
Uma kudingeka ukulawulwa kokugeleza, khetha ivalvu yebhabhathane enezici zokugeleza eziqondile noma ezilinganayo (isb., idiski enomumo ongu-V).
6. Isikhala sokufakwa kanye nesiqondiso sokugeleza:Ivalvu yebhabhathane inesakhiwo esincane, okwenza ifaneleke kumapayipi anesikhala esincane. Ngokuvamile, azikho imikhawulo yesiqondiso sokugeleza, kodwa kumavalvu ebhabhathane anezinhlangothi ezintathu, isiqondiso sokugeleza kumele sichazwe.
II. Izikhathi Ezifanele
1. Izinhlelo Zokulondolozwa Kwamanzi kanye Nokunikezwa Kwamanzi Nokukhipha Amanzi: Ukunikezwa kwamanzi emadolobheni, amapayipi okuvikela umlilo, kanye nokwelashwa kwendle: kuvame ukusetshenziswa amavalvu evemvane aphakathi nendawo avaliwe kahle, ashibhile futhi anokuvala okuthembekile. Ukuze uthole izindawo zokufaka amaphampu kanye nokulawulwa kokugeleza kwamanzi: khetha igiya lezikelemu noma amavalvu evemvane alawula ugesi.
2. Amapayipi e-Petrochemical kanye negesi yemvelo: Amavalvu e-butterfly aboshwe ngensimbi amathathu akhethiwe ukuze amelane nokucindezela okuphezulu kanye nokuvimbela ukuvuza. Imithombo yokugqwala (isb., ama-acid/ama-alkali): Kusetshenziswa amavalvu e-butterfly ane-fluorine noma amavalvu e-alloy amelana nokugqwala.
3. Kwemboni kagesi, izinhlelo zamanzi ezijikelezayo, kanye nokususwa kwe-flue gas: amavalvu ebhabhathane afakwe irabha aphakathi nendawo noma amabili. Kwemibhobho yomusi (isb., izinhlelo zemishini ezisizayo ezitshalweni zamandla): amavalvu amathathu ebhabhathane afakwe insimbi angavamile.
4. Izinhlelo zokujikeleza kwamanzi abandayo nashisayo ze-HVAC (Heating, Ventilation, and Air Conditioning): amavalvu ebhabhathane avaliwe kahle okulawula ukugeleza noma ukuvala.
5. Kobunjiniyela basolwandle kanye namapayipi amanzi olwandle: amavalvu e-butterfly ensimbi engagqwali angenawo ukugqwala noma amavalvu e-butterfly agcwele irabha.
6. Amavalvu ovemvane asezingeni lokudla kanye nelezokwelapha (insimbi engagqwali epholishiwe, izinto zokuxhuma ngokushesha) ahlangabezana nezidingo ezihlanzekile.
7. Uthuli kanye nemidiya yezinhlayiya ezimweni zokusebenza ezikhethekile: Kunconywa amavalvu ebhabhathane aqinile angagugi ayanconywa (isb., ukuthutha impuphu yemayini).
Uhlelo lwe-vacuum: I-vacuum ekhethekileivalvu yebhabhathanekuqinisekisa ukusebenza kokuvala.
III. Isiphetho
I-TWSakuyena nje umlingani othembekile wekhwalithi ephezuluamavalvu ebhabhathanekodwa futhi uziqhenya ngobuchwepheshe obuningi kanye nezixazululo ezifakazelwe kuamavalvu esango, ama-valve okuhlola, futhiamavalvu okukhipha umoya. Kungakhathaliseki ukuthi izidingo zakho zokulawula uketshezi ziyiziphi, sinikeza ukwesekwa kobuchwepheshe, kwe-one-stop valve. Uma ufuna ukusebenzisana noma imibuzo yobuchwepheshe, sicela ukhululeke ukuxhumana nathi nganoma yisiphi isikhathi.
