Valavu yowongolera ma pneumatic ili ndi zida zolumikizira zolondola ndi ntchito zowongolera, ndipo ndiyoyenera nthawi zosiyanasiyana zowongolera. Ili ndi ubwino wa coefficient yothamanga kwambiri, chiŵerengero chachikulu chosinthika, kusindikiza kwapamwamba, mawonekedwe ophatikizika, voliyumu yaying'ono, ndi kuyika kopingasa.
Mawonekedwe a pneumatic proportional control valve:
1. Valve yowongolera sichifunikira kukonzanso kwanthawi yayitali ndipo imakhala ndi moyo wautali wautumiki. Imakupatsirani valavu yomwe imatha kuwongolera momwe zinthu zilili moyenera komanso moyenera.
2. Makhalidwe abwino kwambiri osinthika: Valavu ya mpira yofanana ndi V ili ndi pafupifupi magawo ofanana akuyenda, ndipo chiŵerengero chosinthika ndi 300: 1. Choncho, valavu yagulugufe yooneka ngati V ikhoza kupereka kuwongolera kolondola pakusintha kosiyanasiyana.
3. Kuthamanga kwapamwamba kwa malire: Chifukwa cha streamlined layman ndi kulamulira kozungulira kozungulira kozungulira, malire apamwamba kwambiri akuyenda kwambiri, kutuluka kwake kumakhala kwakukulu kwambiri, ndipo kukana kothamanga kumakhala kochepa, kotero kuti valve yaying'ono ingagwiritsidwe ntchito pachuma. .
4. Mapangidwe amtundu wapawiri amavomerezedwa, ndi kukhazikika kwamakina apamwamba komanso kutsika koyambira koyambira, komwe kumatsimikizira kukhudzidwa ndi kufulumira kwa valve. Kudalirika (chitetezo): Thupi la valve ndi dongosolo lophatikizika la valve, lomwe ndi lolimba komanso lolimba. Kugwira ntchito kwa valavu ya pneumatic proportional control valve sikukhudzidwa ndi kukakamiza kwa mapaipi, komwe kungapewe kutulutsa kwa ma valve.
