MULTIFUNCTIONAL EXTERNAL INFLATING VALVE AND MOUNTING METHOD FOR LOADING DEVICE OF INFLATING VALVE

The present invention provides a multifunctional external inflating valve and a mounting method for a loading device. An inflating valve body of the inflating valve is provided with a three-way through main body, and the main body is through from a side surface by means of a side surface connecting part; the side surface connecting part is used for connecting a loading device; a valve core is arranged in an axial middle hole; a hole cavity is formed in the front portion of the axial middle hole of the main body and used for being connected to an original tire inflating valve; an outer conical surface is arranged on the front portion of the valve core; the front portion, comprising the outer conical surface, of the core protrudes out of the front end of the hole cavity of the main body; and an core conical surface sealing rubber pipe is mounted on the outer conical surface of the core and used for sealing the core and a conical hole sealing surface of a tire inflating valve inner hole cavity. According to the present invention, the problem of an external inflating valve in the past can be avoided, the tire pressure leakage is effectively prevented, the distance between a loading structure and the axis of the inflating valve is closer, and the dynamic balance performance is improved.
