High-pressure steel bottle sealing structure

Abstract

An improvement of a high-pressure steel bottle sealing structure mainly consists of a cover body, a rubber ring and a bottle head whereby the cover body is designed with a convex point at the horizontal bottom which diameter is smaller than that of the inner diameter of the bottle head, and a rubber ring is found at the vertical side edge of the cover body with a thinner diameter than that of the horizontal bottom; the rubber ring is found at the vertical side edge of the cover body stopping at the air passage in order to resist inverse pressure and to prevent air leaking; the bottle head is found at the top of the high-pressure steel bottle and a ring base is designed in the middle of the passage such that the cover body inside stops at the ring base by using the convex point, and an additional length is also left at the bottle head for sealing procedure. Hence, the present invention provides a very rapid air sealing procedure of N 2 O, O 2 or other special gas.

1 . An improvement structure of a high-pressure steel bottle sealing structure mainly consisting of a cover body, a rubber ring and a bottle head, wherein: 
 said cover body is designed with a convex point at the horizontal bottom which diameter is smaller than that of the inner diameter of the bottle head, further, a rubber ring is found at the vertical side edge of the cover body with a thinner diameter than that of the horizontal bottom;    said rubber ring is found at the vertical side edge of the cover body stopping at the air passage in order to resist inverse pressure and to prevent air leaking;    said bottle head is found at the top of the high-pressure steel bottle and a ring base is designed in the middle of the passage such that the cover body inside stops at the ring base by using the convex point, and an additional length is also left at the bottle head for sealing procedure, as characterized.
