Medical oxygen cylinder pressure gauge valve universal

Medical oxygen cylinder pressure gauge valve has universal. The main switch of the medical oxygen cylinder is located in the upper part of the cylinder, with a hand wheel that can be rotated by hand, it is appropriate to rotate the hand wheel half a circle in the counterclockwise direction, the opening angle is too small, which will lead to the pressure can not be completely released, the reading on the oxygen meter may be inaccurate, and it is meaningless to open it too large. When closing, rotate the valve in the clockwise direction, the switching direction of the cylinder is the same as the faucet, you can use the method of switching the faucet to memorize. Whether the oxygen cylinder is closed or not can be confirmed by the pressure gauge on the oxygen meter. After closing the cylinder valve the pressure on the oxygen meter will show a gradual decrease (with the flow regulator switch in the on state) When the pressure gauge shows 0 the bubbles inside the thickening cylinder will gradually decrease to none, which indicates that the oxygen cylinder switch has been closed. After closing the oxygen pressure gauge will gradually return to zero, the humidification bottle will still bubble for a while this is a normal phenomenon.
