The upper face of the valve rod is bolted in the inside of valve rod mounting seat by screw thread, and the lower end of the valve rod is provided with flashboard, described
The upside that the bottom of valve rod is located at flashboard is provided with seal convexity, and the intracavity bottom of the butt tube is provided with sealing ring, the valve body
Inner chamber between two parties be provided with flashboard insertion groove.
It is preferred that, the butt tube is provided with seal washer with valve rod mounting seat contact position.
It is preferred that, the upper end of the valve rod, which is provided with the outside of handlebar stem, the handlebar stem, is socketed with handle sleeve.
It is preferred that, the butt tube is structure as a whole with valve body, and butt tube is connected with the inner chamber of valve body.
It is preferred that, the flashboard is shaped as wedge shape.
It is preferred that, the rounded distribution of the bolt, the bolt is to be placed equidistant.
Compared with prior art, the beneficial effects of the utility model are：The utility model is played by the setting of protective cover
To effect dust-proof inside valve rod mounting seat, pass through the setting of handlebar stem so that the rotation to valve rod is light so that valve rod is downward
When mobile, flashboard is finally inserted after flashboard insertion groove, can be brought into close contact completely with flashboard insertion groove, improves the sealing of flashboard,
Now, seal convexity is also inserted between sealing ring, further improves sealing.
