Description

A kind of air charging system
Technical field
The present invention relates to a kind of air charging system for having pressure regulation and display function, it is suitable for from nitrogen (or oxygen) gas cylinder, to installation There is unidirectional inflation valve and need to accurately adjust inflation/deflation and the pressure regulation of the high pressure accumulator (or damper) of air pressure.Such as aviation field The inflation and pressure regulation of the accumulators such as the buffer or vehicular shock absorber of undercarriage.
Background technique
The similar inflatable high-voltage energy-storage such as undercarriage buffer or vehicular shock absorber of unidirectional inflation valve is installed Device often need to carry out energy storage by the gas of filling, to realize the buffering and damping when work.It is filled to inflatable accumulator Gas filling and accurate tune need to be realized when gas, between high pressure gas cylinder and unidirectional inflation valve by air charging system (or tool) Pressure.Due to the unidirectional inflation valve structure of this kind of accumulator dress is typical, using extensive, by such unidirectional inflation valve to filling Gas formula accumulator need when maintenance filling using easy, and flexible operation, the blowing pressure can reconcile displayable air charging system, Existing accumulator air charging system brings inconvenience to using due to filling, pressure adjusting structure complexity and inconvenient operation.
In addition, inflating excessively to accumulator in order to prevent, pressure regulator valve (relief valve) is generallyd use in the prior art, such as specially Sharp document 1(publication number: CN2864156Y) disclose a kind of pressure regulator valve of inflator pump, the pressure regulator valve be set to inflator pump with Between gas tube, including the ontology with T-shaped threeway, check valve sheet is arranged in interior side, and ontology separately forms surge pipe, Inside setting has the air valve column core of number through-hole, and sheathed spring, air valve seat are set on surge pipe thereon, and spring is located at air valve seat Inside, air valve seat center formed hole can steam supply valve column core wear, inclined-plane is formed on the inside of air valve seat, in being arranged valve on air valve column core Piece and buckle, valve piece, which is located at inclined-plane, to be positioned, and is had the lid in sequence hole in setting in air valve seat, is inflated in inflated object When, if inflated object is filled full, gas can enter surge pipe through check valve sheet, and the pressure of gas can open valve piece, It is released by the perforation of lid, is split or burst explosion with preventing from being inflated object again.However, this kind of pressure regulator valve there are the problem of It is that vent pressure is determined by the preset pressure of spring, as long as just starting when the blowing pressure is greater than the preset pressure Pressure release.Therefore, the blowing pressure that may be only available for being inflated object of this kind of pressure regulator valve is preset, single, nonadjustable, It can not be suitable for a variety of inflated objects of different the blowing pressures, bad adaptability.
