摘要：A 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 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 gas or liquid.
