A gas accumulator and blaster apparatus including a pressure tank (12) and a quick release valve (14). The quick release valve includes an elongated outer sleeve (22), an end cap (28), a check valve (32), a shouldered guide member (38), a cup shaped piston (56), and an annular seat member (68). The
A gas accumulator and blaster apparatus including a pressure tank (12) and a quick release valve (14). The quick release valve includes an elongated outer sleeve (22), an end cap (28), a check valve (32), a shouldered guide member (38), a cup shaped piston (56), and an annular seat member (68). The tank is filled with a gas by means of a conduit (36). The gas accumulated in the tank is quickly exhausted through a second end (26) of the quick release valve and into a storage bin as and when gas is exhausted from interior of the piston, guide member, and conduit. The piston quickly returns to a closed position as and when the flow of air from said tank stops.

A gas accumulator and blaster apparatus for selectively and intermittently fluidizing granular material being contained in storage bins, said apparatus including: (a) a pressure tank for storing a compressed gas, said pressure tank having a selectively located inlet port and a selectively located outlet port; (b) a quick release valve adapted for removable mounting in said outlet port, said quick release valve having a selected portion interior of said pressure tank, said quick release valve including: (b1) an elongated outer sleeve member, said outer sleeve member having a first end a second end, said first end having an end cap fastened thereon in a substantially fluid-tight relationship, said first end also having a check valve provided therein and thereon for allowing uni-directional flow of a pressurized gas from interior of said first end of said outer sleeve member into said pressure tank. (b2) a guide member adapted for being retained interior of said outer sleeve member at a selectively spaced relationship with said end cap, said guide member including a first diameter portion, and a shouldered portion, said first diameter portion adapted for providing a substantially fluid-tight seal with an interior surface of said outer sleeve member, said shouldered portion having a selectively sized second diameter, said shouldered portion projecting from an end of said first diameter portion in a direction distal said end cap, said guide member having a selectively sized circular passageway therethrough, said first diameter portion, said second diameter of said shouldered portion, and said passageway being in a substantially concentric alignment; (b3) a movable substantially cup-shaped piston member, said piston member including a selectively sized outside diameter, a hollow recess, and a nose portion, said nose portion having a selectively angled chamfered edge, said hollow recess being selectively sized to provide a sliding fit with said shouldered portion of said guide member, said hollow recess having a selected depth for allowing said piston member to telescopically move a predetermined amount onto said shouldered portion of said guide member, said outside diameter being selectively sized to provide a clearance fit with said interior surface of said outer sleeve member; (b4) an annular seat member selectively located intermediate said first end and said second end of said outer sleeve member, said seat member adapted for being removably retained within said outer sleeve member, a sealing means for providing a substantially air-tight connection between said annular seat member and said outer sleeve member, said seat member having a selectively sized bore therethrough, said bore having at least one chamfered end, said chamfered end being adapted to mate with the chamfered edge of said nose portion of said piston member for providing a substantially fluid-tight seal as and when desired; (b5) at least one transverse aperture in and through the wall of said sleeve member, said transverse aperture being located in a selected relationship with said chamfered end of said seat member; (c) a conduit member for connecting said inlet port with a through aperture located in said end cap, said conduit member providing a substantially fluid-tight conduit for selectively filling said accumulator and blaster apparatus with said gas and then subsequently exhausting said gas from interior of said piston member and said guide member; and (d) wherein said quick release valve is disposed for allowing said cup shaped piston member to rest on said chamfered end of said annular seat member by gravity for stopping gaseous communication between said transverse aperture and said selectively sized bore in said seat member, said quick release valve further adapted for providing a greater seating force between said piston member and said seat member as and when a gas under pressure is introduced into said guide member and into said hollow recess in said piston member, said quick release valve adapted for quickly urging said piston member away from said seat member as and when said gas under pressure is exhausted from said recess, said guide member, and said conduit; said urged away piston member providing gaseous communication between said transverse aperture and said through bore of said seat member, said communication allowing for any gas under pressure in said pressure tank to escape through said second end.
