Abstract
A tyre conversion valve is provided. The utility model utilizes French-type valve of bicycles for high-grade competitions, which comprises a valve plug in the valve and gland nut connected on the upper part of the valve by rotating. The valve has good air tightness but is inconvenient to charge by common inflator. The design is characterized in that: the original valve is connected with an inflation cap on the upper part by rotating and a sealing ring on the lower part, thus is convenient for the clips of the inflator to charge the tyre on the inflation cap and successfully solves the difficult problem that common French-type valves of the tyre can not be charged by common inflators.
Description
The utility model belongs to the inflation of tire valve.
At present, domestic high-grade bicycles such as racer, its charging valve all adopt a kind of French valve.This French valve is made up of the hold-down nut that valve the inside spool and spool top spin, and spool bottom and valve inner chamber boss contact position are provided with packing seal.When need are inflated, need earlier the hold-down nut on the spool to be unscrewed, spool can be pressed that to open valve promptly inflatable this moment downwards, charge gas and hold-down nut is screwed get final product.This charging valve has the advantage of good airproof performance than other valve.But because this gas nozzle structure can't block the clamp of common Floor Pump, the hose of Floor Pump can only be enclosed within outside the valve and and inflate, bring great inconvenience to use by another people's help.
The purpose of this utility model is that a kind of to be convenient to use common Floor Pump be the gas filed inflation of tire of this French valve conversion valve in design.
This aerated valve or title conversion valve promptly is to spin one on former valve top to inflate cap on the basis of former French valve, and establishes a seal ring between inflation cap and valve boss.
Accompanying drawing is the utility model scheme drawing.
In the accompanying drawing, 2 is French valve spool, and 3 for being screwed in the hold-down nut on spool top, 5 for be positioned at below the hold-down nut, the valve of spool outside, spool 2 bottoms and valve 5 inner chamber boss contact positions are provided with packing seal 6.Be connected with inflation cap 1 more than valve 5 outside boss, inflation cap 1 bottom and valve boss contact position are with seal ring 4.
This novel conversion valve should unclamp hold-down nut earlier when need are inflated, and presses spool downwards with hand, and valve is opened, and will inflate cap again and screw on, and at this moment just can use the clamp of common Floor Pump to block the inflation cap, inflates with Floor Pump.Inflation finishes, and unloads the inflation cap, hold-down nut is screwed to get final product again.The solution of this novel conversion valve success on the tire French valve inconvenience use the gas filed difficult problem of common Floor Pump, for good basis has been laid in the extensive application of French valve on high-grade bicycle of this good airproof performance.
