The invention discloses a novel bottleneck adapter of an internal thread water agent type fire extinguisher. The novel bottleneck adapter comprises a bottleneck adapter body, the bottleneck adapter body comprises an upper circular ring and a lower circular ring, the lower end of the upper circular ring extends into an upper port of the lower circular ring, and the outer wall of the upper circularring is connected with the inner wall of the lower circular ring; and first internal threads are arranged on the inner wall of the upper circular ring from top to bottom, second internal threads are arranged at the positions, between a lower end opening of the lower circular ring and a lower end opening of the upper circular ring, on the inner wall of the lower circular ring, and the internal threads can be prevented from being corroded by water agents by replacing an internal thread bottle with an external thread bottle. The adapter for converting the external threads into the internal threadis made of copper and cannot be corroded by water in a bottle, the requirement that the water agent type fire extinguisher needs to use the internal threads is met, and the time efficiency of the fire extinguisher is guaranteed; and installation is simple, and the adapter is reliable and practical.
Description
technical field [0001] The invention relates to a conversion joint, and more specifically, relates to a new bottle-mouth conversion joint of a water-type fire extinguisher with internal teeth, and belongs to the field of fire-fighting equipment. Background technique [0002] During the handling and storage of internal tooth water-based fire extinguishers, the water agent often penetrates into the internal thread and corrodes the thread. After a long time, it is easy to cause air leakage or even liquid leakage due to damage to the internal thread, which makes the fire extinguisher invalid in advance. Contents of the invention [0003] In order to solve the above-mentioned problems in the prior art, the present invention provides a new type of bottle-mouth adapter for water-based fire extinguishers with simple structure, reliability and practicality. [0004] In order to achieve the above object, the present invention is achieved through the following technical solutions: ...
