By installing sealing gaskets and sealing rings, the overall sealing of the fire hydrant body 1 can be enhanced, which can effectively prevent rainwater and other objects from penetrating into the fire hydrant body 1, and the sealing surface adopts a bevel seal to enhance the sealing performance, which can effectively protect the internal structure of the fire hydrant body 1. By using a powder spraying process to coat the surface of the fire hydrant body 1, the service life of the fire hydrant body 1 can be extended. By adding an air intake valve 41 to the fire hydrant body 1, the drain valve function is ensured to be effective. When the water is used, KWS6 5 When the water outlet cover 36 is installed back to its original position, a vacuum is formed on the plug body, and the drain valve fails to discharge the remaining water. At this time, the air inlet valve 41 works to introduce external air into the plug body, so that the drain valve continues to work, and the remaining water in the plug body is completely drained. The rubber valve disc is installed in an embedded manner to prevent the valve disc from being squeezed and deformed, effectively extending the service life of the valve disc sealing gasket. When the valve is in a closed state, the valve disc is in a compressed state. When the sealing gasket is installed in an embedded manner, the valve disc is in a protective state when the sealing gasket is under pressure, preventing the sealing gasket from being continuously compressed, thereby protecting the service life of the sealing gasket. In addition, since the valve disc 11, the connecting rod 14, the connector 20, and the valve stem 27 are all made of stainless steel corrosion-resistant materials, the overall service life of the fire hydrant body 1 can be extended.
