(1) Mavavu a mpira wa pneumatic
Valavu ya mpira wa pneumatic imakhala ndi valavu ya mpira ndi chowongolera pneumatic.Nthawi zambiri imayenera kugwiritsidwa ntchito molumikizana ndi zida kuphatikiza maginito valve, air treatment FRL, limit switch, ndi positioner kuti ziziwongoleredwa kutali komanso kwanuko komanso kuti zitsegulidwe ndikutsekedwa muchipinda chowongolera.Imawongolera chitetezo, makamaka imapulumutsa mtengo wazinthu za anthu ndi nthawi, ndikupanga kuwongolera pamanja pamalopo, pamwamba pa nthaka komanso m'malo owopsa osafunikiranso.
(2) Magulu a ma valve a mpira wa pneumatic
Malinga ndi nkhaniyi, mavavu mpira pneumatic akhoza kugawidwa mu zitsulo zosapanga dzimbiri pneumatic mpira mavavu, pulasitiki pneumatic mpira mavavu, ukhondo pneumatic mavavu mpira, mpweya zitsulo pneumatic mavavu mpira, kuponyedwa chitsulo pneumatic mavavu mpira, etc.
Malinga ndi njira yolumikizira, mavavu a mpira wa pneumatic amatha kugawidwa kukhala mavavu a mpira wa pneumatic flanged, screw ulusi pneumatic ball valves, welded pneumatic valves, etc.
Malinga ndi kukakamizidwa, mavavu a mpira wa pneumatic amatha kugawidwa kukhala mavavu otsika othamanga a pneumatic, ma valve apakati apakati komanso ma valve othamanga kwambiri.
Malinga ndi malo a tchanelo, mavavu a mpira wa pneumatic amatha kugawidwa kukhala mavavu a mpira wa pneumatic, ma valve a mpira anjira zitatu ndi ma valve akumanja akumanzere.
Malinga ndi mawonekedwe a mpira, mavavu a mpira wa pneumatic amatha kugawidwa kukhala mavavu oyandama a mpira ndi ma valve a mpira wa trunnion.
Mpira woyandama
Mpira wa valavu ya mpira woyandama ukuyandama.Pansi pa kupanikizika kwapakatikati, mpirawo umasuntha ndikukanikizidwa mwamphamvu pamalo osindikizira kumapeto kuti zitsimikizire kusindikiza komaliza.
Mpira wokhazikika
Mpira wa valavu ya mpira wa trunnion umakhazikika, ndipo sudzasuntha pambuyo popanikizidwa.Ma valve onse a trunnion mpira ali ndi mpando wa valve woyandama.Pansi pa kupanikizika kwapakati, valavu imayamba kusuntha kuti mphete yosindikizira isindikizidwe pa mpira kuti zitsimikizire kuti kusindikiza kumagwira ntchito.
(3) Mipira yamagetsi yamagetsi
Valve yamagetsi yamagetsi imapangidwa ndi actuator ndi valavu ya mpira.Ndi mtundu wa chipangizo chimene ntchito mapaipi mu mafakitale zochita zokha ndi ndondomeko ulamuliro.Kunena zowona, nthawi zambiri amagwiritsidwa ntchito poyang'anira zowongolera zapaipi zapa media.
Malinga ndi tanthauzo la valavu yamagetsi yamagetsi mu "Glossary of terms for valves", valavu yamagetsi yamagetsi ndi mtundu wa valavu yomwe ma disks (mipira) imayendetsedwa ndi tsinde la valve, ndiyeno imazungulira kuzungulira kwa valve.Ma valve a mpira wamagetsi amagwiritsidwa ntchito kwambiri podula ndikudutsa pawailesi, kapena amagwiritsidwa ntchito kuwongolera ndi kuwongolera media pamapaipi.Ponena za valavu yolimba yosindikizidwa yooneka ngati V, pali mphamvu yamphamvu yometa ubweya pakati pa mpira wooneka ngati V ndi mpando wa valve wachitsulo wopangidwa ndi kuphimba simenti ya carbide.
(4) Kuyerekeza pakati pa ma valve a mpira wa pneumatic ndi ma valve a mpira wamagetsi
Mtengo
Valavu ya mpira wa pneumatic ili ndi katundu wolemetsa, koma ndiyotsika mtengo kuposa valavu yamagetsi yamagetsi.Chifukwa chake, kugwiritsa ntchito mavavu a mpira wa pneumatic kungachepetse mtengo waukadaulo.
Chitetezo chogwira ntchito
Ogwiritsa ntchito valavu ya mpira wa pneumatic amatha kuyatsa kapena kutseka valve.Pamene valavu yamagetsi yamagetsi ilibe mphamvu, imatha kukhala pamalo ake, yomwe imasonyeza kuti valavu ya mpira wa pneumatic ili ndi ubwino waukulu pa chitetezo.Chifukwa valavu yamagetsi ikatha mphamvu, imatseka kuti ipewe kumbuyo kwa fyuluta ndi spillover.Valavu ya mpira wa pneumatic safuna magetsi, pamene valve yamagetsi yamagetsi imagwiritsa ntchito 220V kapena magawo atatu a 460V.Ndiye kunena kuti, valavu yamagetsi yamagetsi ndi yowopsa kwambiri m'malo onyowa, pomwe valavu ya mpira wa pneumatic simakhudzidwa ndi chilengedwe chonyowa.Ponena za kukonza, n'zosavuta kusunga valavu ya mpira wa pneumatic chifukwa pali gawo limodzi lokha losuntha.Makina opangira magetsi a valve yamagetsi amagetsi amafunika kusamalidwa ndi akatswiri chifukwa cha mbali zambiri za magetsi.
Kachitidwe
Valavu ya mpira wa pneumatic imatha kusintha kuti ikhale yodzaza pafupipafupi.Vavu yamagetsi yamagetsi imakhala yochepa chifukwa cha kuchuluka kwa ma mota komanso nthawi zoyambira zoyambira pa ola limodzi.
Zozungulira moyo
Valavu ya mpira wa pneumatic imakhala ndi moyo wautali wokhala ndi zochita pafupifupi 2 miliyoni.Kubwereza kobwerezabwereza kwa valavu ya mpira wa pneumatic kumatha kuwongoleredwa molondola, komwe kumatha kufika pafupifupi 0.25%.
Kukana dzimbiri
Valavu ya mpira wa pneumatic yokhala ndi zokutira za epoxy mkati ndi kunja kwa pneumatic actuator imasinthasintha kwambiri ndi malo ogwirira ntchito.Imatha kuzolowera malo oyipa ogwirira ntchito monga kuyaka, kuphulika, fumbi, ferromagnetic, radioactive, vibratory environment, etc.
Mbali zina
Pamene valavu ya mpira wa pneumatic sikugwira ntchito bwino, ikhoza kukonzedwa kapena kusinthidwa popanda mphamvu kapena magwero a mpweya.Ponena za kukonza, valavu ya mpira wa pneumatic safuna mafuta, pamene valve yamagetsi yamagetsi imafuna mafuta ambiri.Ponena za ntchito yamanja, valavu ya mpira wa pneumatic imatha kugwiritsidwa ntchito popanda mphamvu.Ponena za liwiro, valavu ya mpira wa pneumatic imagwira ntchito ndikuyankha mwachangu kuti isinthe moyenera.Kuthamanga kwa valve yamagetsi yamagetsi kumakhala kosasintha ndipo sikungasinthidwe.
