1. Maloba ya ebandeli .
Solenoïde valve ezali composant ya base ya automation oyo esalelamaka mpo na ko contrôler fluide, oyo ezali ya actionneur; Ezali kaka te na hydraulique mpe na pneumatique. Ba valves ya solenoïde esalemaka pona ko contrôler direction ya débit hydraulique. Masini ya izini etambwisamaka mingimingi na ba cylindres hydrauliques, yango wana basalelaka ba soupapes ya solenoïde.
2. Makambo oyo ezali na kati .
Ekoki kosala normalement na vide, pression négative, mpe pression zéro, kasi diamètre en général eleki 25 mm te. Ekoki mpe kosala na nse ya bokeseni ya pression zéro, vide, to pression makasi, kasi nguya ezali monene, mpe esengeli kotya yango na ndenge ya horizontal. Limite ya likolo ya esika ya pression ya fluide ezali relativement eleki, mpe ekoki kozala installé arbitrairement (personnalisation esengeli), kasi esengeli kokokisa condition ya différence ya pression ya fluide.
Misato, etinda .
Solenoïde pneumatique ezali na cavité fermée na ba trous na ba positions différentes. Libulu moko na moko ya valve ya solenoïde pneumatique ememaka na tube ekeseni. Na katikati ya cavité ezali na valve. Na ngambo nyonso mibale ezali na ba électromagnés mibale. Mopanzi nini ya bobine ya aimant ezali na nguya wapi nzoto ya valve ekobendama;
The pneumatic solenoid valve blocks or leaks different oil discharge holes by controlling the movement of the valve body, and the oil inlet hole is normally open, the hydraulic oil will enter the different oil discharge pipes, and then the pressure of the pneumatic solenoid valve oil Push the piston of Yugang so that the mechanical movement of the entire solenoid valve is controlled by controlling the current of the electromagnet of the pneumatic solenoid valve.
Ya minei, principe ya fonctionnement ya valve ya solenoïde pneumatique .
Position ya mosala ya solenoïde pneumatique (open to fermé) ezali vraiment ko référer na position ya bobine ya solenoïde pneumatique.
Bobine ezali na position A tango bobine ezali énergisée te, mpe na position B tango bobine ezali energisée. Ntango bobine ya solenoïde pneumatique ezali na ba positions ekeseni, interface moko na moko na nzoto ya valve ekangami to ekangami. Ndakisa, valve ya mibale-Position Solenoïde elakisi ete bobine ya valve ya solenoïde ezali na ba positions mibale ya mosala ekeseni (efungwami to ekangami). Mpo na solenoïde pneumatique, ezali état électrifié ya valve solenoïde mpe de-état énergisé; Mpo na valve, etambwisaka yango ezali kofungola mpe kokanga valve. Mibale-Nzela mpe misato-Ba valves ya solenoïde ya nzela elakisi ete ezali na ba ports mibale to misato ya passage na nzoto ya valve ya solenoïde pneumatique. Mibale-esika mibale-Poloid-nzela ya nzela ezali na ba canaux mibale, moko na kati mpe moko libanda, mpe ezali valve ya solenoïde pneumatique oyo emonanaka mingi; Mibale-Position misato-Solenoïde ya nzela ezali na ba canaux misato na moko na kati mpe mibale libanda, mibale kati na yango ezali ko correspondre connexion ezali normalement ouverte mpe normalement ekangami. Ndenge moko mpe, misato-Nzela, minei-Nzela, mpe mitano-Nzela nyonso ezali kolobela motango ya banzela ya mai na nzoto ya valve.
motoba, etinda ya mosala ya valve ya solenoïde pneumatique .
Na esika ya ebandeli, 1 ezali esika oyo mopɛpɛ ekɔtaka, 2 ezali esika oyo mopɛpɛ ekɔtaka (normalement efungwami), mpe 3 ezali esika oyo mopɛpɛ ekɔtaka (normalement ekangami). 3 mpe 5 ezali mabulu ya kofungola mopɛpɛ. Tango bobine ya valve solenoïde ezali na énergie, noyau ya fer ezuaka force électromagnétique mpo na kosala que valve pilote esala. Salelá mabulu 2 mpe 4 mpo na kobongola nzela, mpe bwaka gaz na mabulu 2. Valve solenoïde esalelamaka mpo na ko contrôler automatisation ya fluide. Ba composants ya base ezali ya actionneur; Bazali kosuka kaka na hydraulique mpe na pneumatique te. Ba valves ya solenoïde esalemaka pona ko contrôler direction ya débit hydraulique. Ba machines ya usine e contrôlé mingi na acier hydraulique, yango wana ba soupapes solenoïdes esalemaka.
Principe ya mosala ya valve ya solenoïde, valve ya solenoïde ezali na cavité fermée na ba trous na ba positions différentes, mpe libulu moko na moko ememaka na tube différent. Na katikati ya cavité ezali na valve. On both sides are two electromagnets, which side is the magnet coil The energized valve body will be attracted to which side, by controlling the movement of the valve body to block or leak out the different drain holes, and the oil inlet hole is normally open, the hydraulic oil will enter the different drain pipes and then pass The oil pressure pushes the oily piston, the piston drives the piston rod, and the piston rod drives the mechanical device mpo na kokende kofanda esika mosusu. Na ndenge wana, mouvement mécanique ezali contrôlé na ko contrôler courant ya électromagnet.
Tracing the development history of solenoid valves, so far, solenoid valves at home and abroad are divided into three major categories in principle, and the differences in the structure and material of the valve disc and the differences in principle are divided into six sub-categories ( Direct-acting diaphragm structure, step-by-step structure, pilot diaphragm structure, direct-acting piston structure, Etape-Na-Etape direct-Kosala structure ya piston, structure ya piston ya pilote).
Solenoïde pneumatique, lokola moko ya ba accessoires communs ya valve pneumatique, e jouaka rôle moko très important, oyo esalemaka mingi mingi pona problème ya retour ya source d'air ya valve pneumatique.
Among them (2/5) two-position five-way solenoid valve is used in conjunction with double-acting pneumatic valves, (2/3) two-position three-way solenoid valve is used in conjunction with single-acting pneumatic valves, and explosion-proof coils can be selected according to the working conditions, Mpo na kozua effet ya explosion-Prignoi, explosion-grade ya préprises ya bobine oyo ezali type encapsulé : ex m ii t4, oyo ekoki kosala normalement na température ambiante ya -20~60 degrés . Ba valves ya solenoïdes ya retour pneumatique ekoki kozala monté na montage to tube selon ba conditions réelles na ba besoins ya valve. Installation yango ezali na boyokani na namur standard mpe na VDI/VDE3845 double libulu, milieu ezali filtré 50 microns, lubrifié, to air comprimé non lubrifié. Interface ya source ya gaz ezali pipe G1/4.
