Embodiment Construction

[0025] The present invention will be described in detail below with reference to the accompanying drawings and examples.

[0026] as attached figure 1 As shown, the present invention provides a sealing and locking member for high-pressure filling. The two ends of the sealing and locking member are cylindrical sections, and the part between the cylindrical sections is a hexagonal structure and a section of threaded section. The hexagonal structure is used to communicate with The external air inlet joint assembly cooperates to realize the transmission of rotational torque, and the threaded section is used to realize threaded connection with the bottle mouth of the bottle body 7; wherein, the diameter of the cylindrical section corresponding to one side of the hexagonal structure is smaller than the length of the opposite side of the hexagonal structure, and the threaded section one The diameter of the cylindrical section corresponding to the side is less than the diameter of the...

Abstract

The invention discloses a seal locking piece achieving high-pressure filling. The two ends of the seal locking piece are cylinder sections, the portion between the cylinder sections is of a hexagonalstructure and a threaded section, the hexagonal structure is used for being matched with an external air inlet connector assembly to achieve running torque transmission, and the threaded section is used for achieving threaded connection with a bottle mouth of a bottle body; the diameter of the cylinder section corresponding to one side of the hexagonal structure is shorter than the length of the opposite edge of the hexagonal structure, the diameter of the cylinder section corresponding to one side of the threaded section is shorter than the diameter of the threaded section, and the end facesof the cylinder sections form sealed faces of the sealed bottle body; and a groove is machined in the hexagonal structure and the threaded section in the axial direction, and the groove penetrates through the hexagonal structure and the threaded section. According to the seal locking piece achieving high-pressure filling, a channel can be provided for meeting the requirements for filling in the filling process, and the channel is sealed by utilizing the self displacement after filling is completed.

Description

technical field [0001] The invention relates to a part for realizing high-pressure pouring, in particular to a part for pouring high-pressure gas or liquid from a liquid (gas) tank into a closed container, and belongs to the technical field of valve sealing structures. Background technique [0002] The high-pressure fire extinguisher is usually filled by a filling mechanism during the filling process. In order to meet the sealing and safety during filling, the bottle body of the high-pressure fire extinguisher must be processed with a filling structure that matches the filling equipment. Currently, the commonly used filling structure is It will occupy relatively large axial and radial spaces on the bottle body, resulting in an excessively large volume of the fire extinguisher. In addition, the existing filling structure is also very complicated, which increases the difficulty of processing and also increases the production cost. [0003] In order to simplify the complexity o...
