Product structure characteristic :
The oxygen pipeline hinders the firearm and adopts special copper alloy and stainless steel to weld . Can prevent the " compressing adiabatically " apt to take shape while suddenly opening of pipeline valve of oxygen effectively , some temperature rises suddenly, become and catch fire energy; Can prevent from around valve pigeonholing difference under the function, material of sport not high-speed particle (such as iron rust, dust, weld dreg,etc.) with after valve pipeline rub, lasted spark of producing and become not lasting energy. The use which hinders the firearm can block the fire source rapidly , stop to fire the emergence of the accident in the pipeline.
