Abstract
Disclosed is a permanent air valve for bicycle. A through-hole thin cylinder which is made by brass material adopts a taper surface, a piston and a sealing rubber type unilateral valve airproof structure to make inflation convenient and smooth. After air entrance, the airproof effect is good and reliable. The structure can not influence the sealing performance because of the change of weather. The utility model is not easy to aging and can be used for a long term.
Description
The utility model relates to a kind of accessory of bicycle, exactly, relates to a kind of permanent valve valve that is used for bicycle tyre.
Present bicycle is to give Tyre inflating and prevent tire gas leakage with the soft rubber ring (claiming again: airtight core or valve inside) that valve and outside cover thereof are wrapped up in.This air valve structure is simple, it is easy to use to make, but also has not little defective: because that it is done with soft rubber ring is airtight, when weather was hot or cold, regular meeting melted or stiff gas leakage of enduring cold because of cushion rubber is heated, and can't ride.And this soft rubber ring is easy to wear out, and with how long not needing replacings, quite feels inconvenience.
The purpose of this utility model provides a kind of bicycle valve valve of novel structure, can use for a long time also can not leak gas or wear out, so claim permanent valve valve.
Structure of the present utility model as shown in Figure 1, it is made up of valve body, piston and seal ring, it is characterized in that valve body 1 is that a centre that makes of brass material is the thin cylindrical body of through hole, one section conical surface 2 is arranged in the hole within it, this conical surface 2 constitutes the one-way valve type airtight construction with the O-ring seal 4 in the T type piston 3 and the outside thereof, O-ring seal 5 also is equipped with in the outside of valve body 1, be provided with pore 6 at the valve body conical surface 2 lower end sidewalls, pore 7 also is equipped with in the valve body bottom, and the valve body upper end is provided with the thread 9 of positioning boss 8 and fastening location.
The utility model is discarded traditional flexible glue cast gas nozzle structure, and adopts cone, piston check valve structure.This structure inflation is convenient, unblocked, and under gas pressure, piston 3 and O-ring seal 4 are close to the conical surface 2 after the air inlet, and airtight effect is reliable, safety.Especially this one-way valve structures its sealability that can not be affected by climate change also is difficult for aging; 5 of O-ring seals are used for airtight between valve valve and the tire.The pore 7 of valve body bottom also has the stroke effect of limited piston 2 when air inlet except air inlet and degassing function.This pore is to shape by the rear end sidewall of valve body 1 being managed behind the v-notch to its central folding is curved again.This air valve long service life.
The utility model is manufactured experimently out a plurality of samples, tests enforcement on bicycle.The designing requirement that facts have proved it can both reach: air inlet is unobstructed, airtight tight.Can bring great convenience to the cyclist if popularize.This air valve structure also is applicable to motorcycle, three-wheel flat car and so on pneumatic tire.
Claims (2)
1, a kind of permanent valve valve that is used for bicycle, form by valve body, piston and seal ring, it is characterized in that valve body 1 is that a centre that makes of brass material is the thin cylindrical body of through hole, one section conical surface 2 is arranged in the hole within it, this conical surface 2 constitutes the one-way valve type airtight construction with the O-ring seal 4 in the T type piston 3 and the outside thereof, O-ring seal 5 also is equipped with in the outside of valve body 1, is provided with pore 6 at the valve body conical surface 2 lower end sidewalls.
2, the permanent valve valve that is used for bicycle as claimed in claim 1 is characterized in that the valve body bottom also is equipped with pore 7, and the valve body upper end is provided with the thread 9 of positioning boss 8 and fastening location.
