flashback arrestor

To prevent such a situation a flashback arrestor is usually employed.

Not to be confused with a flashback arrestor, a check valve is not designed to block a shock wave.

A flashback arrestor is installed in the device to avoid the explosimeter igniting the sample external to the device.

The flashback arrestor will remain switched off until someone resets it, in case the pressure wave created a leak downstream of the arrestor.

A "water torch" is a portable oxyhydrogen torch that combines a DC power supply and an electrolytic cell with a pressure gauge and flashback arrestor.

A flashback arrestor or flame arrestor is a device most commonly used in oxy-fuel welding and cutting to stop the flame from burning back up into the equipment and causing damage or explosions.

Ordinary check valves that normally prevent back flow can not stop a detonation wave as they are not capable of closing before the wave passes around the gate, and for that reason a flashback arrestor is needed.

Between the regulator and hose, and ideally between hose and torch on both oxygen and fuel lines, a flashback arrestor and/or non-return valve (check valve) should be installed to prevent flame or oxygen-fuel mixture being pushed back into either cylinder and damaging the equipment or making a cylinder explode.
