Abstract
The utility model relates to an air valve without a rubber hose, which belongs to the field of a special one-way valve designed for inflation, particularly an air valve used for inflating a tyre. The utility model is composed of an air valve body, an air valve screw cap and a valve needle body, wherein, the center of the valve needle body is provided with a through hole in a processing way, and the middle part of the hole is in a tapered shape; a rubber end plug is matched with the taper hole, and the valve needle body is provided with an air inlet hole which is communicated with the central through hole; the lower part of the valve needle body is provided with an end socket, and spring is installed between the end socket and the rubber end plug. The utility model which has the advantages of simple structure, reliable performance and no need of a rubber hose solves the problem of the air valve leakage caused by the rubber hose; thus, the utility model is a permanent air valve.
Description
The utility model does not have the sebific duct valve and belongs to the one-way valve field that aims at the inflation design, especially for the valve of tyre inflation.
Existing bicycle, rickshaw valve are to be with elastic rubber tube on the conical surface of valve valve body lower portion, as Non-return air valve, and this sebific duct structure, make sebific duct easily be squeezed broken and leak gas, sebific duct is loose excessively, and sealing is poor, the corrosion-resistant of sebific duct, with the passing of time softening, elasticity reduces, and particularly under the cold climate condition, sebific duct is because of low temperature, elasticity obviously weakens, and phenomenon often leaks air.
The purpose of this utility model is to avoid the deficiencies in the prior art part and bicycle, rickshaw valve that a kind of reliable performance, no sebific duct are provided.
The purpose of this utility model reaches by following measure, it is by the valve main body, valve sieve cap, the valve needle body is formed, and is processed into through hole at valve needle body center, and there is a taper at the middle part, hole, that matches with cone shape hole has a rubber plug, the inlet hole that communicates with central through bore is arranged on the valve needle body, and end socket is arranged at valve needle body bottom, between end socket and the rubber plug spring is installed.In order to make the sealing between the gentle door main body of valve needle body more reliable, on the valve main body, be provided with a step, on the valve needle body, be provided with the spill annular groove, on spill annular groove and step, be provided with rubber seal.
The utility model is simple in structure, and reliable performance need not sebific duct, has solved the problem that causes valve blow-by because of sebific duct, is a kind of permanent valve.
Accompanying drawing is a structural representation of the present utility model.
Below in conjunction with accompanying drawing the utility model is further described.
As shown in drawings, the utility model is by valve main body (7), valve sieve cap (2), valve needle body (1) is formed, be processed into a through hole at valve needle body (1) center, there is a taper at the middle part, hole, that matches with cone shape hole has a rubber plug (4), the inlet hole (5) that communicates with central through bore is arranged on the valve needle body (1), end socket (8) is arranged at valve needle body (1) bottom, between end socket (8) and the rubber plug (4) spring (6) is installed, spring (6) withstands on rubber plug (4) in the cone shape hole, makes between inlet hole (5) and valve needle body (1) central through bore to seal, and valve needle body (1) is installed on the valve main body (7), on valve main body (7), be provided with a step, be provided with the spill annular groove on valve needle body (1), be provided with rubber seal (3) on the spill annular groove, rubber seal (3) is stuck on the platform joint of valve main body, valve sieve cap (2) is installed on the valve main body (7), fixedly valve needle body (1).During inflation, pressed gas acts on the rubber plug by central through bore, rubber plug moves down, pressure spring breaks away from rubber plug and cone shape hole, and gas enters tire by inlet hole, along with the increase of gas pressure or when stopping air inlet, rubber plug is return under the effect of air pressure and spring, and cone shape hole is blocked, and rubber seal, rubber plug play sealing.
Claims (2)
1, a kind of no sebific duct valve, it is by the valve main body, valve sieve cap, the valve needle body is formed, and it is characterized in that being processed into through hole at valve needle body center, and there is a taper at the middle part, hole, that matches with cone shape hole has a rubber plug, the inlet hole that communicates with central through bore is arranged on the valve needle body, and end socket is arranged at valve needle body bottom, between end socket and the rubber plug spring is installed.
2, no sebific duct valve according to claim 1 is characterized in that being provided with a step on the valve main body, is provided with the spill annular groove on the valve needle body, is provided with rubber seal on spill annular groove and step.
