摘要：NOVELTY - The valve has a valve rod fixed in an opening and connected with a valve core. An upper end of the valve rod extends out from the opening. A lower end of the valve rod and the opening is filled with filler. A filler gland bush is sleeved on the valve rod. A padding press cover is pressed above the filler and fixed with a valve body. An outer wall of a packing gland is formed with first groove along a circumferential direction. The first groove and a second groove are fixed at a hydrogen absorption reactor. A catalyst coating layer is exposed in the second groove. USE - Hydrogen gas leakage removing function featured hydrogen valve. ADVANTAGE - The valve has simple structure, and safely and effectively removes hydrogen leakage. DESCRIPTION OF DRAWING(S) - The drawing shows a sectional view of a hydrogen gas leakage removing function featured hydrogen valve.
