Specific embodiment
Below in conjunction with attached drawing, elaborate to a preferred embodiment of the utility model.But the guarantor of the utility model
Shield range is not limited to following embodiments, i.e., in every case with simple made by present utility model application the scope of the patents and description
Equivalent changes and modifications all still belong within the utility model patent covering scope.
Refering to fig. 1-5, it is a kind of high-pressure gas seal poppet described in the utility model, including is set to same valve body 1
Two interior and separated with partition 15 valve plate units, each valve plate unit include solid set on the intracorporal circular valve plate 2 of valve, upper end
Due to the valve plate center valve rod 4 and be fixed on outside the valve body downside and connect the cylinder 6 of the valve rod lower end, the valve
The peripheral position that the valve plate is corresponded on the upper side of body is equipped with circular gas storage outer ring 101 and gas storage inner ring 102 forms gas storage
Ring 16, the side valve plate 14 of the valve body are equipped with pressurized gas interface 7 and are connected to the gas storage ring 16.The opening of the poppet and
