Kodi Vavu ya Solenoid Ndi Chiyani Ndipo Imagwira Ntchito Motani?

General

Ma valve a Solenoid amagwiritsidwa ntchito kulikonse komwe madzi amadzimadzi amayenera kuwongoleredwa.Amagwiritsidwa ntchito pamlingo wokulirapo mumitundu yosiyanasiyana ya zomera ndi zida.Mitundu yosiyanasiyana yamitundu yosiyanasiyana yomwe ilipo imathandizira kuti ma valve asankhe kuti agwirizane ndi zomwe zikufunsidwa.

Zomangamanga

Ma valve a Solenoid ndi mayunitsi owongolera omwe, akakhala ndi mphamvu zamagetsi kapena achotsedwa mphamvu, amatseka kapena kulola kutuluka kwamadzi.The actuator amatenga mawonekedwe a electromagnet.Ikapatsidwa mphamvu, mphamvu ya maginito imawunikidwa yomwe imakoka chopondera kapena chopindika motsutsana ndi ntchito ya kasupe.Ikachotsedwa mphamvu, plunger kapena pivoted armature imabwezeretsedwa pomwe idayamba ndi kachitidwe kasupe.

Kuchita kwa Mtengo

Malingana ndi momwe ma actuation amachitira, kusiyana kumapangidwa pakati pa ma valve oyendetsa mwachindunji, ma valve oyendetsa mkati, ndi ma valve oyendetsa kunja.Chinthu chinanso chosiyanitsa ndi chiwerengero cha malumikizidwe a madoko kapena kuchuluka kwa mayendedwe ("njira").

Mavavu ochita molunjika

Ndi valavu ya solenoid yachindunji, chisindikizo chapampando chimamangiriridwa pachimake cha solenoid.Mu chikhalidwe cha de-energized, orifice mpando watsekedwa, umene umatsegula pamene valavu ipatsidwa mphamvu.

Direct-acting2-wayvalves

Mavavu anjira ziwiri ndi ma valve otseka okhala ndi khomo limodzi lolowera ndi khomo limodzi lotulukira.Mu chikhalidwe cha de-energized, kasupe wapakati, mothandizidwa ndi kuthamanga kwa madzi, amasunga chisindikizo cha valve pampando wa valve kuti atseke kutuluka.Mukapatsidwa mphamvu, pachimake ndi chisindikizo zimakokedwa mu coil ya solenoid ndipo valavu imatsegulidwa.Mphamvu yamaginito yamagetsi ndi yayikulu kuposa mphamvu yamasika yophatikizika komanso mphamvu zokhazikika komanso zosunthika zapakati.

Direct-acting3-wayvalves

Ma valve a njira zitatu ali ndi ma doko atatu ndi mipando iwiri ya valve.Chisindikizo chimodzi cha valve nthawi zonse chimakhala chotseguka ndipo chinacho chimatsekedwa mopanda mphamvu.Pamene coil ipatsidwa mphamvu, njirayo imabwerera.Valavu ya 3-way idapangidwa ndi plunger mtundu wapakati.Ntchito zosiyanasiyana za valve zingapezeke molingana ndi momwe sing'anga yamadzimadzi imalumikizidwa ndi madoko ogwira ntchito.Kuthamanga kwamadzimadzi kumawonjezeka pansi pa mpando wa valve.Ndi coil de-energized, kasupe wa conical amagwirizira chisindikizo cham'munsi mwamphamvu kumpando wa valve ndikutseka kutuluka kwamadzimadzi.Doko la A latopa kudzera mu R. Koyiloyo ikapatsidwa mphamvu pachimake chimakokedwa, mpando wa valve ku Port R umasindikizidwa ndi chisindikizo chapamwamba cha masika.Sing'anga yamadzimadzi tsopano imayenda kuchokera ku P kupita ku A.
