Abstract
The utility model relates to an opening and closing device for an air valve on a vehicle tyre, which is composed of a valve body and a valve core. When inflating, the air valve is sealed by the valve core in the air valve; when inflation is end, the valve core automatically seal an air outlet hole by the pushing of a spring of the air valve. The utility model overcomes the shortage that the prior art is easy to leak when inflating. When in use, the opening and closing device for an air valve saves time and labor. As the utility model has simple structure and convenient operation, the opening and closing device for an air valve can be widely used for inflating automobiles, motorcycles, and bicycles.
Description
The utility model belongs to vehicular traffic tyre inflation instrument, particularly a kind of valve valve switch.
The various vehicles of modern society have become the indispensable instrument of mankind's activity, the tire of automobile, motorcycle or bicycle all needs inflation just can travel, existing technology inflation method is divided into direct aeration: promptly earlier the venting valve on the valve is backed out, and then be connected on the valve venting valve of screwing on again after the inflation with the inflator joint; Another kind method is the joint aeration: be screwed in above the vehicle tyre valve with a joint earlier, and then be connected on the valve with the valve joint, after gas is full of, back out joint, the shortcoming that above-mentioned two kinds of methods exist is to work as to turn on charging air inlet, when inflating, tire will be exitted, to become flat after being full of gas, like this, time-consuming effort again, do not reach promising result, and the utility model designed can be air tight at gas replenishment process, be full of the valve valve switch that does not become flat behind the gas, be not reported.
A kind of gastight valve valve switch that the utility model purpose provides in order to overcome above-mentioned shortcoming just.
The utility model is achieved in that
Illustrated below in conjunction with accompanying drawing
Accompanying drawing: valve valve switch structure schematic representation
It is made up of valve body 1 and spool 2.
Using steel material that the profile of valve body 1 is made diameter one end during manufacturing is thick shape, in addition One end is the shape of thin shape, and has the circular hole of M8 * 0.8-7Y-S6 millimeter at butt end, Taper end has 22 millimeters apertures of 3 millimeters deep, and two holes communicate, and the taper end profile is the swallow-wing shape, Spool 2 these spool shapes are housed in the butt end circular hole are convex shape, it is 1 that the centre has diameter The through hole of millimeter communicates with the through hole of valve body 1 the inside after the assembling, and the material of this spool is used rubber Glue material is made.
When the utility model uses, earlier the valve valve switch is screwed on the cranked tire valve, this The time valve and valve switch be in sealing state, the sealing gasket (spool 2) in the valve switch Boss contacts with valve, so gas can not overflowed in the tire; When inflating, because Gas pressure is greater than car body valve spring pressure, but the gas unseat the valve inflate, when Sealing gasket contacts with sealing gasket again under the bounce effect of spring when not inflating, thereby rises To sealing function.
Advantage of the present utility model is to use this device, and is air tight in the time of can ensuring to tyre inflation, is full of the gas rear tyre and do not become flat, and during use, saves time and laborsaving, overcome the existing technology inflator shortcoming of gas leakage easily.
Claims (2)
1, a kind of valve valve switch that is used for the vehicular traffic tire is made up of valve body (1) and spool (2); It is characterized in that described valve body external diameter one end is thick, the other end is thin, have the circular hole of M8 * 0.8-7Y-S6 millimeter in the butt end position, thin end has 3 millimeters of , dark 22 millimeters apertures, two holes communicate, thin end profile is the swallow-wing shape, and spool 2 is housed in the butt end circular hole, and the spool shape is convex shape, it is 1 millimeter through hole that the centre has diameter, and the assembling back communicates with the through hole of valve body 1 the inside.
2, valve valve switch according to claim 1 is characterized in that valve body is copper material, and spool is made for the rubber material.
