Description

Technical Field

[0001] The utility model belongs to the technical field of external valves, and in particular relates to an external valve with a quick connection function. Background Art

[0002] An air compressor is a device used to compress gas. The structure of an air compressor is similar to that of a water pump. Most air compressors are reciprocating piston type, with rotating blades or rotating screws. When an air compressor is used, a valve is required to connect it. When the valve is installed externally, it may take a long time and the installation may be unstable. Therefore, an external valve that can be quickly connected is required.

[0003] For example, the Chinese patent with the publication number CN220037750U discloses a quick connection structure of a valve, including a valve body and two first connecting pieces, the inlet and outlet of the valve body are provided with threads. One end of the first connecting piece is provided with a threaded protrusion adapted to the threads at the inlet and outlet of the valve body, the edge of the other end of the first connecting piece is provided with a first connecting protrusion, and the two first connecting pieces are respectively screwed to the inlet and outlet of the valve body through the threaded protrusions. The end of the second connecting piece connected to the first connecting piece is provided with a second connecting protrusion adapted to the first connecting protrusion, a first clamp is installed at the connection between the first connecting protrusion and the second connecting protrusion, and the inner surface of the first clamp is provided with a groove for clamping the first connecting protrusion and the second connecting protrusion.

[0004] The patent has the following problems:

[0005] In the prior art documents, it is not convenient to quickly install and use the external valve when it is connected to the air compressor. There is no installation tool when installing the external valve, so the external valve cannot be quickly installed, thereby reducing the installation efficiency of the external valve. In addition, in the prior art documents, it is not convenient to connect and install the external valve with pipes of different models, thereby reducing the diversity and expansibility of the external valve connection. In view of this, we propose an external valve with a quick connection function. Utility Model Content
