Ma valve a Solenoid amagawidwa malinga ndi momwe amakhalira, mtundu wa ntchito, ndi ntchito yozungulira. Zonsezi ziyenera kufotokozedwa posankha valavu yatsopano ya solenoid ndikuyiphatikiza mu dongosolo lomwe liripo. Monga mtundu wina uliwonse wa ma valve oyambira okha, ma valve a solenoid nthawi zambiri amagawidwa molingana ndi momwe amakhalira (mphamvu-yozimitsa). Izi zikuwonetsanso kulephera kwake{4}}malo otetezeka. Mphamvu ikadulidwa, kasupe mkati mwa valavu ya solenoid imabwezeretsa plunger pamalo ake onse.
1. Nthawi zambiri valavu yotsegula ya solenoid
Valavu yotseguka ya solenoid imatsegulidwa mphamvu ikazima. Yambitsani valavu ya solenoid kuti mutseke valavu. Izi ndizothandiza kwambiri pakugwiritsa ntchito komwe mpweya kapena mpweya uyenera kusungidwa mudongosolo panthawi yamagetsi.
2. Nthawi zambiri kutsekedwa solenoid valve
Mosiyana ndi valavu yotseguka ya solenoid, yotsekedwa nthawi zambiri imatanthawuza kuti yatsekedwa pamene sikugwira ntchito. Valavu imatsegulidwa potumiza magetsi kudzera mu valve solenoid. Nthawi zambiri ma valve a solenoid otsekedwa amakhala ochulukirapo kuposa otseguka. Ntchito zambiri zimafuna kuzimitsidwa kapena kudzipatula kwa mapaipi adongosolo pakalephereka kwadongosolo.
3. Vavu ya Bistable solenoid
Nthawi zambiri ma valve otseguka komanso otsekedwa amakhala ngati ma valve okhazikika. Kumbali ina, ma valve a bistable solenoid ali ndi valavu yachiwiri ya solenoid m'malo mwa njira yobwerera masika. Alibe malo abwinobwino. Akamayamba, amakhalabe momwemo ngakhale magetsi azima.
Gulu lina la ma valve solenoid ndi mtundu wa ntchito. Iwo akhoza adamulowetsa kudzera njira ziwiri zazikulu. Mtundu woyamba ndi zochita zachindunji, zomwe zimadalira kwathunthu mphamvu yamagetsi yopangidwa ndi solenoid. Chotsatira ndicho kugwiritsa ntchito mphamvu yoperekedwa ndi payipi yoyendetsa ndege kudzera mu njira yosadziwika. Njirazi zitha kuphatikizidwanso kuti apange valavu yoyendetsedwa ndi mphamvu yamagetsi yamagetsi komanso kuthamanga kwa mapaipi.
4. Chindunji-valavu ya solenoid
Kwa mtundu uwu wa valve solenoid, kuthamanga kwa static kumawonjezeka ndi kuwonjezeka kwa kukula kwa orifice. Kuwonjezeka kwa static pressure kumafuna mphamvu yamphamvu ya valve solenoid. Choncho, mphamvu ya maginito ndi yamphamvu. Izi zikutanthauza kuti pamlingo wina wa kupsyinjika kwa pneumatic, kuthamanga kwakukulu kumafuna solenoid yaikulu. Ndiye kuthamanga ndi kuthamanga kwa kuthamanga kumayenderana ndi kukula kwa solenoid. Mtundu uwu wa valavu ya solenoid nthawi zambiri umagwiritsidwa ntchito ndi maulendo ang'onoang'ono othamanga ndi zovuta zogwirira ntchito.
5. Valavu yamkati yoyendetsa solenoid
Pogwiritsa ntchito-kuthamanga kwambiri komanso kuthamanga kwambiri{1}}mavavu oyendetsa oyendetsa amkati amagwiritsidwa ntchito. Mu mtundu uwu wa valve, valve imatsegulidwa kapena kutsekedwa ndi kuthamanga kwa madzi. Kuti izi zitheke, potsegula dzenje kapena dzenje lolinganiza anaikidwa. Mapangidwe anthawi zonse amaphatikizapo kutsekereza kwapakati pa orifice. Vavu ikatsekedwa, mpweya umadutsa m'mphepete mwake ndipo kupanikizika kumapangidwira mbali zonse za diaphragm. Malingana ngati mpweya watsekedwa, mphamvu yotseka idzapangidwa chifukwa cha malo akuluakulu ogwira ntchito pamwamba pa diaphragm. Vavu ikatsegulidwa, pachimake cha valve chidzatsegula chotulukapo, potero kumasula kupanikizika pamwamba pa diaphragm. Ndiye kuthamanga kwa payipi kumatsegula valavu.
6. Valavu yakunja yoyendetsa solenoid
Valavu yamtunduwu imatenga lingaliro lofanana ndi valavu yoyendetsa mkati, koma kupanikizika komwe kumagwiritsidwa ntchito kuyendetsa valavu kumachokera ku mpweya woperekedwa kunja. Mpweya wosiyana umaphatikizidwa mu valve kudzera pa doko lowonjezera. Mavavu onse amkati ndi akunja oyendetsa solenoid amatchedwa mavavu osalunjika kapena a servo-mavavu othandizidwa, ndipo mphamvu yawo yayikulu imachokera ku kusiyana pakati pa mapaipi okwera ndi otsika a valve.
7. Semi-chindunji-valavu ya solenoid
Semi-chinthu chachindunji chimaphatikiza mfundo za mavavu achindunji ndi osalunjika. Kuphatikiza pa mphamvu ya maginito yochokera ku solenoid, kusiyana kwapakati pa malekezero onse a valve kumathandiza kutsegula kapena kutseka valve. Pamene plunger yatsegulidwa, diaphragm imakwezedwa kuti atsegule valve. Panthaŵi imodzimodziyo, kutseguka kwa dzenje limodzi kumapangitsa kuti mphamvu yomwe ili pamwamba pa diaphragm ituluke. Kutseka dzenje kudzera pa plunger kumapangitsa kuti pakhale kuthamanga kwambiri pamwamba pa diaphragm, potero kutseka valavu. Pomaliza, ma valve solenoid amagawidwanso molingana ndi ntchito zawo zozungulira. Atha kukhala ngati valavu yosavuta yodzipatula, yopereka chithandizo chanjira imodzi yoyenda. Ntchito zina zimafuna maulendo angapo. Chitsanzo chimodzi ndi silinda yomwe imafuna njira zoponderezedwa komanso zotulutsa mpweya.
8. Mavavu-awiri a solenoid (2/2 way valve) :
Mitundu iyi ya ma valve solenoid ili ndi doko lakumtunda ndi doko lakumunsi. Ndiwo mitundu yofunikira kwambiri, yomwe imagwiritsidwa ntchito kutsekereza kapena kulola kuyenda kwa mpweya. Mavavu awiri-a njira ya solenoid amapezeka m'mapangidwe awiri: nthawi zambiri amakhala otseguka komanso otsekedwa.
9. Vavu -yanjira zitatu (3/2-way valve) :
Mavavu atatu-wanjira ya solenoid ali ndi madoko atatu: cholowera (chotsekera), chotulutsa ndi chotuluka (cholowera). Iwo ali ndi zigawo ziwiri. Mayiko awiriwa amagwiritsa ntchito mosinthana ndikutulutsa mphamvu kuchokera ku actuator kapena zida zapansi.
Njira zitatu-vavu ya solenoid imathanso kukhazikitsidwa kuti ikhale yotseguka komanso yotsekedwa, ndikuwonjezera ntchito yapadziko lonse lapansi. Kwa vavu yotseguka-yanjira zitatu, valavu itazimitsidwa-yamphamvu, mpweya umayenda kuchokera polowera mpweya kupita kolowera, ndipo khomo lotulutsa mpweya limatsekedwa. Akayatsidwa, cholowera mpweya chimatsekedwa ndipo cholumikizira mpweya chimalumikizidwa ndi doko lotulutsa mpweya. Mkhalidwe wa ma valve omwe nthawi zambiri amatsekedwa ndi zosiyana. Kumbali inayi, ntchito yayikulu imagwiritsidwa ntchito posankha kusintha koyenda kuchokera ku doko lina kupita ku lina.
10. Vavu -wanjira 4/2):
Ma valavu anayi-wanjira anayi ali ndi madoko anayi: cholowera chimodzi (chitseko chopondereza), madoko awiri otulutsa kapena ma actuator, ndi khomo limodzi lotulutsa mpweya. Magawo awiri a valve iyi amalola kuti kupanikizika kuyendetsedwe kuchokera ku doko loponderezedwa kupita kumodzi mwa madoko otulutsira, ndikutulutsa mphamvu kuchokera ku doko lina kupita ku doko lotulutsa mpweya. Palibe malo omwe amakhala otseguka kapena otsekedwa. Amagwira ntchito ngati ma valve owongolera.
11. Vavu -yanjira zisanu (5/2-way valve)
Valovu ya five-way solenoid ndi yofanana ndi four-valavu, kupatula kuti ili ndi khomo lowonjezera lachiwiri. Amagwiranso ntchito ngati ma valve owongolera, omwe amalola kuyenda papaipi imodzi ndikutuluka kwina. Paipi iliyonse imakhala ndi doko lodziyimira palokha. Chifukwa cha kuthamanga kwa mpweya wosiyanasiyana wa mizere iwiriyi, njira zisanu-zovala za solenoid ndizopambana kuposa zinayi-valavu ya solenoid. Mukagwiritsidwa ntchito pawiri-pawiri, kuthamanga kwa silinda (kapena kufutukula) kwa silinda kumatha kukhala kwachangu kuposa liwiro lokulitsa.
12. Vavu -yanjira zisanu ndi imodzi yokhala ndi malo apakati (vavu yanjira 5/3) :
Mitundu iyi ya ma valve solenoid ndi ofanana ndi ma valve wamba a 5/2-way, koma amakhala ndi malo owonjezera pamikhalidwe yabwinobwino. Ali ndi ma solenoids awiri ndi njira ziwiri zobwerera masika kuti alole actuator kubwerera. Mitundu yosiyanasiyana ya mavavu a 5/3-way amagawidwa molingana ndi ntchito zawo pansi pazikhalidwe zabwinobwino. Nthawi zambiri, mkhalidwe wabwinobwino ndi "malo osasunthika" a valavu omwe amasunga chowongolera kuti chikhale pamalo.
Pamwambapa pali Mitundu ya ma valve a pneumatic solenoid ndi ntchito zake, kuti mudziwe zambiri zokhudzana ndi izi zikupezeka pa https://www.joosungauto.com/.
