Poppet shear protection apparatus and system

A shear protection system, said system comprising:

• a cylinder for containing a compressed gas or liquid;
• a valve connected to said cylinder, said valve including an inlet;
• and
• a shear protection device intermediate said cylinder and said valve, said shear protection device including:
• a poppet, said poppet including a bore and wherein said poppet includes first and second openings at distal ends of said poppet;
• a retainer plug attached to the second opening of said poppet, said retainer plug enclosing said poppet bore;
• a seat plug disposed in said poppet bore, wherein said seat plug is moveable within said poppet bore;
• said poppet and said retainer plug being constructed and arranged to envelope said seat plug;
• a shear tube with first and second ends extending through said first opening of said poppet, said first end abutting said seat plug through said first opening of said poppet and wherein said shear tube displaces said seat plug from the top of said poppet bore, and wherein the second end of said shear tube attaches to the inlet of said valve;
• said shear tube being constructed and arranged to secure said set plug against said retainer plug;
• wherein said compressed gas or liquid passes through said poppet into said valve;
• and
• wherein said seat plug forcibly engages the top of said poppet bore when said shear tube is removed, blocking the flow of said compressed gas or liquid.

A shear protection device, said shear protection device comprising:

• a poppet, said poppet including a bore and wherein said bore includes at least two diameters and wherein said poppet includes at least one ventilation opening and wherein said poppet includes first and second openings at distal ends of said poppet;
• a seat plug disposed in the poppet bore, wherein said seat plug is moveable within said poppet bore;
• a retainer plug attached to the second opening of the poppet, said retainer plug enclosing said poppet bore and wherein said poppet and said retainer plug envelope said seat plug, wherein said retainer plug includes at least one ventilation shaft;
• a shear tube with first and second ends extending through said first opening of said poppet, said first end abutting said seat plug and said second end attached to a valve and wherein said shear tube engages said seat plug against said retainer plug when attached to the valve;
• wherein said poppet is attachable to the valve, when attached, a compressed gas or liquid can pass through said poppet into the valve;
• wherein said seat plug is forcibly engaging the top of said poppet bore when said shear tube is removed and wherein said seat plug blocks the flow of said compressed gas or liquid.
