[0017] Example embodiments will now be described more fully with reference to the accompanying drawings. However, example embodiments can be implemented in many forms and should not be construed as limited to the examples set forth herein; rather, these embodiments are provided so that this disclosure will be more thorough and complete and will fully convey the concepts of the example embodiments to those skilled in the art.

[0018] See also Figure 1The figure shows a schematic structural diagram of the accumulator charging pressure gauge assembly provided by the present invention, comprising a charging valve 1, a pressure gauge 2, and a housing 3. The housing 3 is provided with a channel 1 31 along the axial direction. One end of the channel 1 31 is sealedly connected to the pressure gauge 2, and the other end is provided with a charging port 33. The housing 3 is also provided with a channel 2 32 and a groove 34. One end of the channel 2 32 is connected to the channel 1 31, and the other end is connected to the groove 34. The charging valve 1 avoids the channel 2 32 and is sealed with the groove 34. One end of the channel 1 31 is a stepped channel that cooperates with the probe end of the pressure gauge 2. The probe end of the pressure gauge 2 is placed in the channel 1 31, and the end with the larger diameter is connected to the channel 1 31 by a thread. A spring washer 21 and an adjustment washer 22 are provided between the pressure gauge 2 and the housing 3. The end with the smaller diameter of the pressure gauge 2 probe end is provided with a protective ring 23 and a sealing ring 24. There are two protective rings 23, one at each end of the sealing ring 24. The groove 34 is sealed with the charging port hole axis of the charging valve 1. The threaded connection between the pressure gauge 2 and the channel 1 31 is coated with anaerobic thread fastening glue.

[0019] When the charging valve 1 is inflated, the gas enters the channel 1 31 through the channel 2 32 and then passes through the charging port 33 to charge the system accumulator with air pressure energy. The probe end of the pressure gauge 2 detects the current accumulator pressure value in real time, closes the charging valve 1, and seals the hole shaft to achieve the sealing function of the product.

[0020] The integrated charging valve 1 and pressure gauge 2 enable forward charging and reverse shutoff. Pressure gauge 2 is always connected to the accumulator, displaying the current accumulator pressure in real time. The seal between pressure gauge 2 and housing 3 utilizes a bore-shaft seal, enhancing product sealing. The sealing structure between charging valve 1 and housing 3 utilizes the valve's own sealing ring 11 for end-face sealing.
