Valve A 5/2Ndi mtundu wa valavu ya chibayo yomwe imawongolera kuwongolera kwa mpweya mkati mwa chida cha chibayo, makamaka kuti mupange masilinda. The "asanu" amatanthauza kuchuluka kwa madoko (kulumikizana), ndipo "2" amatanthauza kuchuluka kwa maudindo (akuti valavu ikhoza kukhala). Momwe Umagwirira Ntchito:
Zigawo zazikuluzikulu za falve zisanu ndi ziwiri:
Madoko 5:
P (kupsinjika): doko logwirizana ndi mpweya.
Yankho: Port yolumikizidwa ndi gawo limodzi la silinda (kapena womugwira).
B: Part yolumikizidwa ndi nkhope yotsutsana ndi silinda (kapena womugwira).
EA (TOMWE A): Dongosolo lotulutsa mpweya lomwe limapangitsa wochita seweroli pomwe valavu imasuntha munjira imodzi.
Eb (tulud b): Dongosolo lotulutsa mpweya lomwe limapangitsa sewerolo pomwe valavu imasuntha.
Maudindo awiri:
Valavuyo ili ndi maudindo awiri omwe amasintha njira yoyandama, kuwongolera momwe mpweya umalowamo ndikutulutsa wochita setiotor.
Momwe zimagwirira ntchito:
malo 1 (omasuka / de {{1}
Chigwachi chikaperekedwa (kapena "pumula"), madoko amakonzedwa motere:
Port P (Kutumiza kwa mpweya) kumalumikizana ndi doko la disili (imodzi ya silinda).
Port B (mbali ina ya silinda) imasungidwa mpaka poct eya, yomwe imalola mpweya kuti mutuluke makinawo.
Port Eb yatsekedwa, kuyimitsa mpweya kuti asathawe padoko B.
Kusintha kumeneku kumakankhira pisitoni mkati mwa cylinder kupita ku 1 gawo (mwachitsanzo, kuwonjezera piston).
Maudindo awiri (malo ophatikizika / omwe ali ndi mphamvu):
Pomwe valavu imalimbikitsidwa (mwachitsanzo, pamene alnoid idayambitsidwa), njira yamkati imasandulika valavu pachilango chake, ndikusintha njira:
Port p (mpweya wa ndege) tsopano amalumikizana ndi doko B, kutumiza mpweya mbali ina ya silinda.
Port A tsopano amalumikizidwa ndi port eb, kuloleza mpweya kuti athetse kuchokera mbali ina ya silinda.
Port EA yatsekedwa.
Kuchita izi kumapangitsa pistoni mkati mwa njira yosemphana (mwachitsanzo, kuvomereza pisitoni).
Glo Hide Valve a 5/2 valavu:
Cholinga cha valavu ya 5/2 ndikuwongolera kupita ndi mpweya m'njira yomwe imatsitsimutsa njira ya siyilesi yowonjezera iwiri {{}}:
Pa gawo 1, mpweya umangolowera gawo limodzi la silinda (lolani kuti anene doko), ndi mpweya panjira ina (padoko b) watopa thru e.
Pofika 2, njira ya Airflow imabwezeretsedwa: Air imalumikizidwa mbali ina ya cylinder (thru padoko b), ndipo mpweya mbali inayo ya silinda imatopa kudzera pa Eb.
Ntchito Zofala:
Pawiri -} valani ya 5/2}}}
Zojambula zamagetsi: Ma valves asanu / awiri amatsimikiziridwa mu zida zokha ngati zopangira, zopereka, zongoyang'anira, pomwe kuyenda mobwerezabwereza kumafunikira.
Masitaelo a Protution Wa Valave A 5/2:
Buku: Othandizidwa ndi thandizo la wotsogolera lever, batani, kapena kusamutsa.
Solenodoid {{0} yoyendetsedwa: yokonzedwa pogwiritsa ntchito coil wa solenoid, zomwe nthawi zambiri zimayendetsedwa bwino.
Chizindikiro cha chibayo: chimachita chizindikiritso china cha ma pneumatic china (nthawi zambiri chimatchedwa kuti woyendetsa {0 {0} adayendetsa kapena woyendetsa ndege {
Makina: Atha kuchitidwa pogwiritsa ntchito njira zamakina, kuphatikiza masika kapena makina a Cam.
Zochita za opareshoni:
Chipinda cha 57 chitsogozo chimatsogolera ku Airfflow madoko ogulitsa, kuwongolera kayendedwe ka skillinder iwiri {}}.
Pamalo amodzi, mpweya umayenda mbali imodzi ya silinda imodzi, kukankhira pisitoni munjira imodzi ngakhale mpweya wolimba kuchokera mbali inayo.
Mwa mbali inayo, mpweyawo umasinthidwa, kulola pisitoni kuti isunthire m'njira zosiyanasiyana.
Valavu iyi imalola kusintha zida zoyenera zamagetsi mu maluso okhalitsa kudzera pakusintha njira ya ochita ndege kwa ochita opaleshoni.
