| Summary: | The utility model discloses a tyre valve, comprising a vent pipe (1) and a valve pipe (2). The vent pipe (2) is connected with the valve pipe (1) in a thread mode, and the connecting position is sealed by a sealing ring (3). The inner wall of the vent pipe (2) is approach to the port of the vent pipe and is provided with an annular air valve (4), and an air valve plug with a thimble (7) with a handle shape is tightly pressed on the air valve (4). The port of the vent pipe (2) is sealed by the internal sealing pad (9) of an air valve cover (8). Therefore, if the valve is broken to leak air, the vent pipe only needs to be disassembled and replaced, and a tyre tube does not need to be replaced. The bore diameter of the air valve is enlarged, and inflating speed can be accelerated. The air valve cover is sealed twice, and the airtight performance is reliable. The tyre valve has simple structure and convenience for processing and manufacturing, and the tyre valve can be made of copper and iron materials. The tyre valve can reduce production cost. |
