Chidziwitso - Vacuum Valves

I. Kuyambitsa vavu
Vacuum valve ndi gawo la vacuum system lomwe limagwiritsidwa ntchito posintha momwe mpweya umayendera, kusintha kukula kwa gasi, kudula kapena kulumikiza payipi mu vacuum system.Mbali zotsekera za vacuum vacuum zimasindikizidwa ndi chisindikizo cha rabara kapena chisindikizo chachitsulo.

II.Kugwiritsa ntchito vacuum vacuum wamba.
Mavavu a vacuum
Imagwiritsidwa ntchito pazida zapamwamba kapena zapamwamba kwambiri pamene vacuum iyenera kusamalidwa munjira yotsekera vacuum.Ma vacuum valves amagwiritsidwa ntchito kuwongolera kutuluka kwa mpweya kulowa mchipinda chochotseramo, kudzipatula, kutulutsa mpweya, kupereka kuchepetsa kuthamanga kapena kuwongolera.Mavavu a zipata, ma valve olowera mkati ndi ma angle valves ndi mitundu yodziwika bwino ya vacuum vacuum yomwe imagwiritsidwa ntchito popanga vacuum apamwamba kapena okwera kwambiri.Mitundu yowonjezera ya valavu imaphatikizapo ma valve a butterfly, ma valve osinthira, ma valve a mpira, ma valve a pendulum, ma valve azitsulo zonse, vacuum vacuum, ma valve a aluminiyumu, ma valve otsekemera a Teflon ndi ma valve owongoka.

Mavavu a butterfly
ndi mavavu otsegula othamanga okhala ndi ma disc achitsulo kapena ma vavu omwe amapindika m'makona akumanja kupita komwe akudutsa mupaipi ndipo akamazungulira pama axis awo, mavavuwo amasindikiza mpando wa ma valve.

Mavavu osinthira (mavavu ampata amakona anayi)
Ma valve olekanitsa oyenera kugwiritsidwa ntchito pakati pa zipinda zotsekera zotsekera ndi zipinda zosinthira, komanso pakati pa zipinda zosinthira ndi zipinda zopangira zida zopangira semiconductor.

Ma Vacuum Ball Valves
ndi ma valve oyenda mozungulira kotala okhala ndi zotsekera zozungulira zokhala ndi mipando yozungulira yofananira yosindikiza kupsinjika kofanana.

Ma valve a pendulum
ndi valavu yaikulu throttle woyikidwa pakati ndondomeko vacuum chipinda ndi turbomolecular mpope polowera.Mavavu a vacuum pendulum amapangidwa ngati ma valve a chipata kapena pendulum kuti agwiritse ntchito kuphatikiza OLED, FPD ndi PV mafakitale opanga makina.

Mavavu azitsulo zonse
Zapangidwa kuti zigwiritsidwe ntchito m'malo otsekemera kwambiri omwe kutentha kwambiri sikulola kugwiritsa ntchito ma elastomers ndi zitsulo za cryogenic gasket.Mavavu azitsulo zonse zophika amapereka kusindikiza kodalirika kwa kutentha kuchokera mumlengalenga mpaka pansi pa 10-11 mbar.

Mavavu a vacuum
Imagwira ntchito modalirika pamakina opanga ma semiconductor komanso m'mapulogalamu okhala ndi mankhwala komanso kuipitsidwa ndi tinthu.Atha kugwiritsidwa ntchito m'malo opanda vacuum, vacuum yayikulu kapena malo otsekemera kwambiri.

Aluminium angle valves
Kulowetsa ndi kutuluka kwa mavavuwa kuli pa ngodya zabwino kwa wina ndi mzake.Ma valve a ngodya awa amapangidwa ndi aluminiyumu A6061-T6 ndipo amagwiritsidwa ntchito popanga zida za semiconductor ndi zida, R&D ndi makina ochotsera vacuum m'mafakitale kuti agwiritse ntchito kwambiri vacuum.

Vavu ya Vacuum ya Teflon ndi chida chopangidwa bwino ndi chitsulo chosapanga dzimbiri chokhala ndi zokutira zolimba komanso zosagwira mankhwala.

III.Makhalidwe a vacuum valves.
Kupanikizika kuli pansi pa mphamvu ya mumlengalenga ndipo kutsika kwapakati pa valve ya valve sikungathe kupitirira 1 kg mphamvu / masentimita.Kutentha kogwira ntchito kwa sing'anga kumadalira ndondomeko ya chipangizo chogwiritsidwa ntchito.Kutentha nthawi zambiri sikudutsa -70 ~ 150 ° C.Chofunikira kwambiri pa ma valve oterowo ndikuwonetsetsa kuti pali kulumikizana kwakukulu komanso kulimba kwa kapangidwe kake ndi gasket.

Malinga ndi sing'anga kuthamanga vakuyumu mavavu akhoza kugawidwa m'magulu anayi.
1) Mavavu otsekemera otsika: kuthamanga kwapakati p = 760 ~ 1 mmHg.
2）Mavavu apakatikati: p=1×10-3 mmHg.
3) Mavavu apamwamba kwambiri: p=1×10-4 ~1×10-7 mmHg.
4）Vavu yovumbulutsa kwambiri: p≤1 × 10-8 mmHg.

Monga valavu yotsekedwa yokhala ndi m'mimba mwake yosakwana 250 mm, tsinde lomwe limagwiritsidwa ntchito kwambiri ndi vacuum bellows shut-off valve ndi kayendedwe ka mzere.Ma valve a zipata, komabe, amakhala oletsedwa kwambiri, koma izi ndizomwe zimakhala zazikulu kwambiri.Zomwe ziliponso ndi ma valavu ozungulira (mavavu a mpira), mavavu a plunger ndi agulugufe.Mavavu opangira ma vacuum vacuum sanakwezedwe chifukwa amafunikira mafuta opaka mafuta, zomwe zimapangitsa kuti mpweya wamafuta ulowe mu vacuum system, zomwe siziloledwa.Mavavu otsekemera amatha kuwongoleredwa pamanja komanso patali m'munda, komanso magetsi, ma elekitirodi (ma valve solenoid), pneumatically ndi hydraulically.
