Valavu ya Mpira wa Pneumatic Three-way

Valavu ya mpira wa pneumatic ya njira zitatu imagwiritsidwa ntchito makamaka poyendetsa kapena kulamulira kulumikizana kwa media mu dongosolo la mapaipi, yoyenera njira zokha zomwe zimafuna kusinthana kwa kayendedwe ka ...
Fomu ya njira ya valve ball channel ingasankhidwe ngati L, T kapena Y malinga ndi zosowa za njira, kuti ikwaniritse zofunikira za njira zosiyanasiyana zoyendera komanso njira zowongolera. Kapangidwe ka njira koyenera kamalola valve kusunga njira yoyenda bwino komanso yodalirika panthawi yopatuka kapena kusakanikirana, zomwe zimathandiza kuchepetsa chiopsezo cha kusagwira ntchito bwino kwa dongosolo.
Malo olephera a actuator amatha kusankhidwa malinga ndi zofunikira pa njira ndi chitetezo, ndipo amatha kukhazikitsidwa ngati malo otsegulira zolakwika, kutseka zolakwika kapena malo ogwirira zolakwika. Valavu imathandizira ntchito yakomweko ndi yowongolera kutali, ndipo imatha kukhazikitsidwa ndi malo oimikapo magalimoto, ma switch oletsa, ma solenoid valves ndi ma module olumikizirana kuti athandize kulumikizana ndi machitidwe a DCS kapena PLC, zomwe zimathandiza kuyang'anira pakati ndi kuyang'anira momwe ntchito ikuyendera.
Nthawi yogwirira ntchito ya valavu imatha kusankhidwa malinga ndi momwe zinthu zilili, yoyenera nthawi zonse ziwiri zomwe zimafuna kusinthana mwachangu komanso njira zomwe zimafunikira kuti kusinthana kukhale koyenera. Ikagwiritsidwa ntchito ngati valavu yosinthira kapena valavu yolumikizirana, imatha kukulitsa kusinthasintha ndi kudalirika kwa magwiridwe antchito a dongosolo.
