A springless shear protection device for use with a valve, the device comprising a poppet, the poppet including a bore. The poppet including first and second openings at distal ends of the poppet. A seat plug is disposed in the poppet bore, the seat plug is moveable within the poppet bore. A shear tube with first and second ends extending through the first opening of the poppet, the first end abutting the seat plug through the first opening of the poppet and the shear tube displacing the seat plug from the top of the poppet bore. The poppet is attachable to the valve and when attached a compressed gas or liquid passes through the poppet into the valve. When the shear tube is removed, the seat plug forcibly engages the top of the poppet bore and the seat plug blocks the flow of the compressed gas or liquid.

We claim the following invention: 1. A shear protection device for use with a valve, the device comprising: 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
We claim the following invention: 1. A shear protection device for use with a valve, the device comprising: 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 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; said shear tube being constructed and arranged to secure said seat plug against said retainer plug; wherein when said poppet is attachable to the valve, a compressed gas or liquid passes through the poppet into the valve; and wherein said compressed gas or liquid causes said seat plug to forcibly engage the top of said poppet bore when said shear tube is removed and wherein said seat plug blocks the flow of the gas or liquid. 2. The shear protection device of claim 1, wherein said bore of said poppet includes at least two diameters. 3. The shear protection device of claim 1, wherein said poppet includes at least one ventilation opening. 4. The shear protection device of claim 3, wherein said poppet includes ventilation openings around the periphery of said poppet. 5. The shear protection device of claim 4, wherein said ventilation openings around the periphery of said poppet are opposed across said poppet bore. 6. The shear protection device of claim 5, wherein said ventilation openings opposed-include four sets of ventilation openings. 7. The shear protection device of claim 1, wherein said poppet includes an O-ring positioned in said poppet bore. 8. The shear protection device of claim 7, wherein said retainer plug at least one ventilation shaft. 9. The shear protection device of claim 1, wherein said shear tube includes a second end attached to the valve. 10. The shear protection device of claim 9, wherein said second end of said shear tube is press fit to the valve. 11. The shear protection device of claim 1, wherein said shear tube is made from brass. 12. The shear protection device of claim 1, wherein the valve includes a relief device. 13. The shear protection device of claim 12, wherein said relief device operates to release said compressed gas or liquid. 14. The shear protection device of claim 1, wherein said poppet is manufactured from stainless steel. 15. The shear protection device of claim 1, wherein said second end of said shear tube is fixedly attached to the valve. 16. 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. 17. The shear protection system of claim 16, wherein said valve includes a relief device. 18. The shear protection system of claim 16 further including a mobile trailer connected to said cylinder, said mobile trailer for the transportation of said cylinder, said valve and said shear protection device. 19. The shear protection system of claim 16 further comprising a second shear protection device connected to said valve. 20. The shear protection system of claim 19, wherein said second shear protection device is located in series with said first shear protection device. 21. The shear protection system of claim 19, wherein said second shear protection device-includes: a second poppet, said second poppet including a bore and wherein said second poppet includes first and second openings at distal ends of said second poppet; a second seat plug disposed in said second poppet bore, wherein said second seat plug is moveable within said second poppet bore; a second shear tube with first and second ends extending through said first opening of said second poppet, said first end of the second shear tube abutting said second seat plug through said first opening of said second poppet and wherein said second shear tube displaces said second seat plug from the top of said second poppet bore; wherein compressed gas or liquid passes through said second poppet into said valve; and wherein said second seat plug forcibly engages the top of said second poppet bore when said second shear tube is removed, blocking the flow of said compressed gas or liquid. 22. The shear protection system of claim 21, wherein the first and second shear protection devices are on substantially the same axis. 23. The shear protection system of claim 16, wherein said first shear protection device mates directly with said cylinder. 24. The shear protection system of claim 16 further including a bullplug between said cylinder and said first shear protection device, wherein said bullplug includes first and second threaded connections, wherein said first threaded connection mates with said cylinder. 25. The shear protection system of claim 24, wherein a diameter of said first threaded connection is larger than the diameter of said second threaded connection. 26. 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.
