Abstract

The invention discloses a vacuum plug for LNG liquefied natural gas bottle, relates to the technical field of liquefied natural gas equipment, and comprises a C-shaped sealing ring, a first O-shaped sealing ring and several second O-shaped sealing rings; the plug seat is hollow Cylindrical structure, the inside is divided into a first opening chamber, a connecting chamber and a second opening chamber from inside to outside, and the diameters of the first opening chamber and the second opening chamber are larger than the diameter of the connecting chamber; the plug The body is a cylindrical structure, and the diameter of the plug body is adapted to the diameter of the second opening chamber; a first annular groove and several second annular grooves are opened on the plug body; a column is also arranged inside the plug body Plug body, the diameter of the plunger body matches the diameter of the connecting chamber; a third annular groove is opened on the plunger body; the C-shaped sealing ring is clamped in the third annular groove; the first O-shaped sealing ring It is clamped in the first annular groove; each second O-ring is clamped in a corresponding second annular groove.

Description

technical field [0001] The invention relates to the technical field of liquefied natural gas equipment, in particular to a vacuum plug for LNG liquefied natural gas cylinders. Background technique [0002] The vacuum plug of the LNG liquefied natural gas cylinder is the only part to ensure the lasting and stable vacuum degree of the interlayer of the LNG liquefied natural gas cylinder. The vacuum plugs of the original LNG liquefied natural gas cylinders all adopt a single-stage sealing structure, which has problems such as low sealing efficiency, poor stability, and high difficulty in manufacturing operations. With the continuous development and innovation of vehicle-mounted LNG liquefied natural gas cylinder processing technology, the requirements for the rationality and reliability of vehicle-mounted LNG liquefied natural gas cylinder structure technology continue to increase. In order to meet more scientific, reasonable, safe and reliable application requirements for veh...
