Oxyhydrogen Flashback Arrestor Torch (OHT-1)
In order that there is no flashback appeared when user closes valve, the torch adopts the precise manufacturing technology like watch-maker to built in a flashback arrestor between the valve and nozzle.

5. The features of the oxyhydrogen flashback arrestor torch:
The flashback arrestor, which is installed in the gas out end of valve, can keep from backfire and protect the sealing ring of
valve when there is any back-fire. Therefore it can extend the service life of valve sealing ring.
Some torches in the present market cannot keep the machine from backfire, the sealing ring of torch valve will lost effectivenessafter using some time so that it will cause back-fire. Some install the flashback arrestor in the gas-in end of valve, therefore, it will hurt the sealing ring when there is any back-fire, let back-fire enter into the gas-out end of flashback arrestor, it may cause that the flame is still burning in the exit of flashback arrestor after closed valve so thatit will damage the torch.
As a result, our oxyhydrogen torch has installed a flashback arrestor in the front of valve. If there is any back-fire when closing the valve, the flashback arrestor will stop back-fire entering into the valve automatically. So the flashback arrestor will flame out automatically because of no gas, the flame won't reach to the valve forever and sealing ring will get the efficient protection.
