Air pressure visible air valve

The invention discloses an air pressure visible air valve which comprises a connector. An adjusting button is rotationally arranged at the top of the connector. An adjusting rod is fixedly connected to the adjusting button. A display window is formed in the side face of the adjusting rod. An air pressure identification block is arranged in the display window and slides in the display window. An air pressure quantity indicator lamp is further arranged on the side face of the adjusting rod. The display window is a narrow closed window. Due to the fact that the narrow display window is formed in the side face of the adjusting rod of the air pressure visible air valve and the sliding block capable of sliding according to the magnitude of the air pressure is arranged in the window, when the air pressure in a pipeline is changed, the position of the sliding block is changed, the change of the air pressure in the pipeline can be visually seen, and use of the air valve is greatly facilitated.
