Abstract
A novel air valve structure for an inner pipe air cylinder comprises a piston seat, piston rings mounted in upper ring grooves in the outer part of the piston seat, sealing rings mounted in middle ring grooves in the outer part of the piston seat, piston cups with downward mouth openings, and self-tapping screws for fixing the piston seat which is inversely inserted into the upper end of an air cylinder inner pipe, wherein the piston cups penetrate through lower ring grooves in the outer part of the piston seat. The novel air valve structure is simple in structure, less in components, and less in sealing parts. According to the air valve structure, the assembling of the piston rings, the sealing rings, the piston cups and the like with the piston seat is simple, convenient, fast and efficient, an assembled air valve assembly is inversely inserted into the upper end of the air cylinder inner pipe through the piston seat, and then is fixed through the self-tapping screw, sealing between the air valve assembly and the inner pipe is realized through the sealing rings mounted in the middle ring grooves in the outer part of the piston seat to complete the combination of the air valve assembly and the air cylinder inner pipe, then the upper end of the inner pipe and the air valve assembly mounted at the upper end of the inner pipe are inserted into an outer pipe of an air cylinder, and other procedures for inner pipe air cylinder production are carried out, so that inner pipe air cylinder products can be produced quickly, and the air cylinder production capacity of enterprises is greatly improved.
Description
Technical field
The present invention relates to a kind of novel interior pipe inflator air valve structure, is that the one of internal pipe inflator air valve structure is improved.
Background technique
Inflator is used for for various tire and some gas ball objects inject or fill into air, so far the indispensable instrument of the one having developed into people's daily life from coming out, its evolution experienced by by the revolution of leather cup type inflator to interior pipe inflator, the interior pipe inflator of nowadays the present inventor's design has become the main flow on market, but the present inventor recent studies have found that: to be designed by the present inventor and pipe inflator (number of patent application 00201090.9) also comes with some shortcomings in applying for a patent in 2000, problem is by spool, valve body, valve pad, the air valve structure component that piston seat and seal ring combination are formed are many, Sealing is many, production and assembly efficiency is low, the serious reduction of obstruction cost of production and the development of enterprise.
Summary of the invention
The object of the invention is to overcome above-mentioned the deficiencies in the prior art, and provide the Novel valve structure that a kind of structure of interior pipe inflator is simple, component are few, Sealing is few, simple and convenient assembly is quick, manufacturing efficiency is high, i.e. a kind of novel interior pipe inflator air valve structure.
Object of the present invention can be realized by such technological scheme: this structure is simple, component are few, Sealing is few, simple and convenient assembly is quick, the novel interior pipe inflator air valve structure that manufacturing efficiency is high, it comprises piston seat, be contained in the piston ring in annular groove on piston seat outside, be contained in the seal ring in piston seat outside in annular groove and the downward piston cup of dehiscing by the outer subordinate's annular groove device of piston seat, and be inserted in thread tapping fixing after pipe upper tip in inflator for piston seat, described piston seat outside offers the air inlet breach communicated between annular groove with the upper-end surface of piston seat, logical piston seat upper-end surface is set in the body of piston seat, the air flue of the sidewall in lower logical piston seat outside between annular groove and lower annular groove.Interior pipe inflator air valve structure like this: the parts such as piston ring, seal ring, piston cup and piston seat simple and convenient assembly quick, valve assembly after assembling is inserted in the upper tip of pipe in inflator by piston seat, then fix with thread tapping, namely by being contained in the seal ring realization in piston seat outside in annular groove and the sealing between interior pipe, complete the combination of pipe in valve assembly and inflator, afterwards the valve assembly that interior pipe upper end and interior pipe upper end are installed is inserted in the outer tube of inflator, again through other operations that interior pipe inflator is produced, interior pipe inflator product can be produced fast.And the interior pipe inflator product manufactured: when outer tube is upwards mentioned, the piston ring be contained on piston seat outside in annular groove can be subject to the effect of outer tube friction promotion upwards and outer tube inner air and outer air Negative Pressure Difference and upward sliding, sealing between piston seat and outer tube is opened, make ambient air can enter in outer tube via the air inlet breach that annular groove on the gap between piston seat and outer tube, piston seat outside and piston seat outside are offered between annular groove and piston seat upper-end surface, complete the gas storage in outer tube, when outer tube is pressed downward, the piston ring be contained on piston seat outside in annular groove can be subject to again the effect of the downward friction promotion of outer tube and outer tube inner air and outer air positive differential pressure and slide downward, gap between piston seat and outer tube is closed, make the air in outer tube can only via the upper airway flow arranged in piston pedestal to annular groove in piston seat outside and the sidewall between lower annular groove and the gap between interior pipe, proceed to the piston cup of dehiscing downward of the outer subordinate's annular groove device of piston seat behind, along with outer tube is pressed down further, piston cup behind air pressure increases, after piston cup is pressed towards internal strain, the air flue of the pressurized air stored in outer tube namely by arranging in piston pedestal, in piston seat outside, the sidewall between annular groove and lower annular groove and the gap between interior pipe enter interior pipe, and then be that needs inject or fill into the tire of air or gas ball objects is inflated by the band of gas that is communicated with interior pipe and charging air inlet.
This novel interior pipe inflator air valve structure structure provided by the present invention is simple, component are few, Sealing is few, simple and convenient assembly is quick, efficiency is high, the inflator throughput of enterprise can be increased substantially, to reduction inflator cost of production, the improving product market competitiveness and promoting enterprise development are all significant.
