Abstract
The utility model discloses no rubber tube valve belongs to the special check valve field that designs for aerifing, especially is used for the inflated valve of tire, and it is by the valve main part, valve nut, and valve needle body is constituteed, processes into the through-hole at valve needle body center, and there is a toper hole at the hole middle part, and with bell mouth matched with there is a rubber end cap, have on the valve needle body with the communicating inlet port of central through-hole, there is the head valve needle body lower part, installs the spring between head and the rubber end cap. The utility model discloses simple structure, the dependable performance need not the rubber tube, has solved the problem that causes the valve gas leakage because of the rubber tube, is a permanent 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.
