Detailed Description
The following description of preferred embodiments of the present utility model is provided in connection with the accompanying drawings, and it is to be understood that the preferred embodiments described herein are for the purpose of illustration and explanation only and are not intended to limit the utility model thereto.
As shown in fig. 1, the dual-air-pressure detection type tire inflation device comprises an air source 1, an inflation valve 2 and a controller 3, wherein the air outlet end of the air source 1 is connected with the air inlet end of the inflation valve 2 through a first air passage 4, and the air outlet end of the inflation valve 2 is connected with a tire through a second air passage 5, so that the tire is inflated.
The first air passage 4 is connected with a first pressure sensor 61 in an air passage way, the second air passage 5 is connected with a second pressure sensor 62 and an exhaust valve 7 in an air passage way, the controller 3 is connected with the charging valve 2, the first pressure sensor 61, the second pressure sensor 62 and the exhaust valve 7 in an electric circuit way at the same time, the on-off of the charging valve 2 and the exhaust valve 7 is controlled, and the first pressure sensor 61 detects the air pressure of the first air passage 4 and the second pressure sensor 62 detects the air pressure of the second air passage 5.
Thus, when the inflation valve 2 is opened, if the pressure value detected by the first pressure sensor 61 is greater than the first preset value and/or the pressure value detected by the second pressure sensor 62 is greater than the second preset value, this indicates that there is a possibility of component failure at this time, that is, damage to the air path may occur, or damage to the inflation valve 2 occurs, and at this time, the exhaust valve 7 needs to be opened to perform pressure relief to prevent excessive inflation of the tire.
When the inflation valve 2 is opened, if the pressure difference between the first pressure sensor 61 and the second pressure sensor 62 is greater than the third preset value, it is determined that the first pressure sensor 61 and/or the second pressure sensor 62 are/is malfunctioning at this time, and the exhaust valve 7 can be opened to release pressure at this time, so as to prevent excessive inflation of the tire.
In the above scheme, set up pressure sensor respectively between air supply 1 and inflation valve 2, inflation valve 2 and tire and carry out atmospheric pressure detection to two gas circuits, and the difference between two data and the two data that detect compares with the default, whether the whole aerating device has the component to take place to damage to the analysis judgement, after closing inflation valve 2, can also detect the pressure of air supply through pressure sensor, can avoid the tire to take place the risk of overshooting, spreading value is high.
Further, the inflation valve 2 can be provided with a plurality of in parallel in this scheme, through the break-make of the inflation valve 2 of control different quantity, can realize the regulation to the inflation volume, can reach quick inflation, accurate effect of inflating, and when one of them inflation valve 2 takes place to damage, also can use other inflation valves 2 to aerify, ensured the inflation efficiency.
