Bottle fill valve

Abstract

The invention discloses a charge-limiting cylinder valve. A diverting hole is formed in a flow chamber of the cylinder valve, a ferromagnetic sphere capable of sealing the upper end port of the diverting hole is arranged in the upper end of the diverting hole, the upper end port of the diverting hole is eccentrically arranged in the flow chamber, a space capable of accommodating the ferromagnetic sphere away from the upper end port of the diverting hole is formed in one side, drifting from the diverting hole of the flow chamber, the upper end face of the diverting hole, corresponding the space, is arranged in a manner of inclining downwards to the diverting hole, a flow guide plate capable of swaying up and down is mounted above the space, and the swaying end of the flow guide plate inclines downwards to the upper side of the ferromagnetic sphere and extends to guide the charging medium to the position between the ferromagnetic sphere to the cavity wall of one side, away from the accommodating space, of the flow chamber.. By the charge-limiting cylinder valve, smoothness of a charging flow path guaranteed, and illegal dumping can be effectively prevented.

Description

technical field [0001] The invention relates to the technical field of bottle valves, in particular to a bottle valve that can be applied to verification identification to restrict filling. Background technique [0002] Liquefied gas filling is an industry strictly regulated by the state. In order to facilitate industry management, identification has been used to strengthen the management of liquefied gas filling. Add identification tags to the steel cylinders respectively. When filling, the gas can only be inflated after the identification labels on the steel cylinders pass the identification of the identification device on the gas filling gun. coming security risks. [0003] In a published document (liquefied gas cylinder valve CN202188214U), it uses an inclined magnetized closure to open and close the diversion hole of the cylinder valve. When inflating, after the identification instrument on the inflating gun recognizes the logo of the steel cylinder, the electromagnet...

AI Technical Summary

Problems solved by technology

The unrecognized steel cylinder cannot start the electromagnetic generator, and the closure is in the state of closing the diversion hole and cannot be inflated

However, when this bottle valve is inflated, the inflation pressure will be too high. When the inflation pressure is greater than the electromagnetic force, it will press the opened closure to close the diversion hole, resulting in inability to inflate.

It can be seen that there are still defects in the use of this bottle valve, and it is difficult to ensure the smooth flow of the gas path when inflating

[0004] In the current liquefied gas filling industry, because the traditional bottle valve does not have an anti-dumping device, there are often staff who operate illegally and dump the filling medium in the bottle, which is not allowed by industry management
