Abstract

Gas injection valve pressure for installations materials pneumatic conveying powders, granules or similar, comprising: --a circular tubular outer body provided at both ends, sendas clamp and placed in an outdoor pipe radial position for gas inlet pressure, --a tubular body internal located inside the body and external introduces two wallonia circulares, near its ends and tightly arranged relative to the inner wall of the outer body presenting the valona --in downstream flow direction material a transportar-- longitudinal holes a series of willing coaxial and circumferentially; and delimiting an annular chamber between said circular and related surfaces wallonia interior and exterior outer body of the inner body, and the latter also has prolongations sendas axle tubular end, being placed the aguasarriba beveled on its inside, --a lid circular by way of clamp, whose central hole has, ranging from its front side to the rear, a first zone cilíndrica, a second tapered zone and a third zone cilíndrica larger diameter determining the latter a escalon with the largest base of the second zona frustoconical; and said cap presents a short pipe cylindrical axially projecting from its rear face has its free edge bevelled internal surface is part of the third area cilíndrica, and the outer diameter of said pipe is set to the diameter inside the end placed downstream outer body; and other delimiting annular space between the third zone circular cylinder cover with your escalon and the corresponding outer surface of the tubular extension of the internal body downstream with your valona; also delimiting an annular gap between zones first circular second cilindricay frustoconical central hole of the lid and the outer end surface of the tubular extension of the internal body downstream, 'and a stretch membrane cross shaped washer, superimposed supported against valona internal body provided with longitudinal holes a what is covered and is secured, circumferential and peripherally at a distance of said holes longitudinal between said valona and singing the edge free beveled pipe top acting this membrane springy as non-return valve.
