ES288741U - Electrovalvula of diaphragm (Machine-translation by Google Translate, not legally binding) - Google Patents

Abstract

Diaphragm solenoid valve, essentially characterized by being constituted from a casing, preferably made of plastic material, obtained by the functional combination of a body and a lid, duly fixed to each other, an inlet line and an outlet line being established in the body, independent by means of an intermediate partition determining an orthogonal bend for the inlet conduit and a circular hole with axis perpendicular to said inlet conduit and determining a valve seat on which an obturator assembly housed in a cylindrical extension extends. Coaxial body with the valve seat itself and through which said body receives the lid, with the particularity that said lid has a lateral expansion, in correspondence with the outlet line, on which is placed and fixed an electromagnet whose core mobile acts as a shutter for an established driving ent a defined chamber within said expansion in which said movable core plays, and the outlet conduit, while said chamber, by another lateral conduction, is related to the chamber established above the membrane or diaphragm of the valve, located in correspondence with the connection plane between the body and the lid, with the particular feature that said chamber superior to the diaphragm, in a closed valve situation, communicates with the inlet line, in order to recover the closing situation upon deexcitation the electromagnet, through an axial hole in the obturator assembly.
