Abstract
The utility model discloses an overpressure automatic releasing air valve which belongs to the technical field of the air valve. The utility model is composed of an air valve, a valve core in the air valve and a sealing ring, wherein the valve core comprises a valve core body, a valve core rod on the valve core body, a sealing spring and a sealing nut. The utility model is characterized in that the valve core is also provided with an overpressure automatic releasing mechanism composed of an overpressure releasing sealing ring, an overpressure releasing holder, an overpressure releasing spring and an overpressure releasing nut. The air valve can be provided with a screw thread on the end part of a valve base or the air valve to be provided with the valve core with the overpressure automatic releasing mechanism. By selecting or adjusting the matched combination with different elastic force of the sealing spring and the overpressure releasing spring, the set values of different pressure of an inner cavity of a vehicle wheel can be obtained correspondingly. Whenever an overpressure is produced, the pressure of the inner cavity of the vehicle wheel is automatically deflated to release the overpressure so as to ensure the safety of the vehicle wheel and the traffic. The improved overpressure automatic releasing air valve has the advantages of simple structure and convenient fabrication and installation, which can replace the existing air valve and can be popularized and applied to vehicle wheels of various vehicles.
Description
One. technical field
The disclosed valve cock that unloads superpressure automatically of the utility model belongs to the valve cock technical field.Be specifically related to a kind ofly can when wheel inner chamber superpressure, unload the valve cock of superpressure by automatic deflation.
Two. background technique
Wheel such as wheel for motor vehicle (car-wheel), manpower wheel's (bicycle quick) etc. of inflation have plenty of the air of filling certain pressure with the inner tube of a tyre, have plenty of the air that the inner chamber that forms with cover tire and wheel rim driving fit is filled certain pressure.Every performance of the wheel of inflation and the gas pressure that fills in it are closely related.Along with the increase of interior pressure, can obtain bigger load-carrying ability.But the air pressure that fills in the wheel increases, and can produce shock-absorbing capacity reduction, Sheng Regao, heat radiation and wait the result slowly.Too high at the interior air pressure that fills, when surpassing the pressure set points that inner chamber can carry, will influence the safety of wheel, accidents such as explosion, explosion appear.If can guarantee technically that chamber pressure is no more than setting value, can limit car load on the one hand can not overload, the safety of tire in the time of can increasing for a long time operation continuously on the one hand.
People know that the wheel inflation inner chamber and the passage of extraneous exchange are valve cocks.Used valve inside structurally is an one-way valve, and the wheel inflation time is opened, and charges that the gas valve inside resets and keep airtight under gas pressure.Its venting promotes the valve core bar by external force and finishes.The valve cock that the present invention is designed when keeping former valve cock function, has been done improvement on the structure.When the valve cock after the improvement surpasses setting value at the inner chamber gas pressure, can unload the superpressure venting automatically, make the wheel chamber pressure still remain on the pressure work down of setting.Obviously improved this valve cock is suitable, safer more, is worthy of popularization.
Three. summary of the invention
