[0029] The right sides of the second pressure regulator 9 and the first pressure regulator 10 are both fixedly connected with a secondary three-way joint 11 through a pipeline, and the top side of the secondary three-way joint 11 is fixedly connected with a bleed valve component 12 through a pipeline. The secondary three-way joint 11 receives the regulated airflow from the first pressure regulator 10 and the second pressure regulator 9, and guides the airflow to the bleed valve component 12. The bleed valve component 12 can release excess air pressure when the system pressure is too high to ensure the safe operation of the system. The main bracket 2 is fixedly connected to the right end of the top side of the base 1, and the reinforcing plate 3 is fixedly connected to the right end of the top side of the base 1. The right side of the reinforcing plate 3 is fixedly connected to the left side of the main bracket 2, and is fixed and stands on the base 1 through the main bracket 2 and the reinforcing plate 3. The inner wall of the main bracket 2 is fixedly connected with a magnetic seat 4, and the left side of the magnetic seat 4 is fixedly connected with a turbocharger body 5. The magnetic seat 4 provides a stable fixing point to ensure that the turbocharger body 5 remains stable during operation and reduces the accuracy loss caused by vibration or movement.

[0030] Reference Figure 1 and Figure 4 The left side of the main bracket 2 is fixedly connected to the right side of the turbocharger body 5, and the top side of the turbocharger body 5 is fixedly connected to the bottom side of the air release valve component 12 to provide support for subsequent components. The top side of the turbocharger body 5 is fixedly connected with a fixing component for providing support for subsequent components. The fixing component includes an air release valve bracket 14, the bottom side of the air release valve bracket 14 is fixedly connected to the top side of the turbocharger body 5, and the top side of the magnetic seat 4 is fixedly connected with a fixing rod. The top side of the fixing rod is fixedly connected with a dial indicator 13 through a pipeline, which provides an intuitive pressure reading for the operator, making the pressure regulation more accurate. The right end of the rear side of the air release valve bracket 14 is fixedly connected with a rocker arm 15, and the rear end of the fixed component is fixedly connected with an air release valve adjustment sleeve 17. The interior of the rocker arm 15 is fixedly connected to the exterior of the air release valve adjustment sleeve 17, and the inner wall of the air release valve adjustment sleeve 17 is fixedly connected with an air release valve stem 16, and the right side of the air release valve stem 16 is fixedly connected with a dial indicator 13.

[0031] Working principle: The gas is guided into the inside of the two air pipes 18 through the main three-way joint 6, and then the two air pipes 18 guide the air flow to the first pressure regulator 10 and the second pressure regulator 9 respectively. The two pressure regulators are independently controlled by the first switch 7 and the second switch 8, so as to achieve precise adjustment of the turbocharger pressure. The pressure-regulated air flow is sent to the bleed valve component 12 through the secondary three-way joint 11. When the system pressure is too high, the bleed valve component 12 can release excess air pressure to ensure the safe operation of the system. In order to improve stability and reduce the impact of vibration on accuracy, the turbocharger body 5 is firmly fixed on the base 1 through the cooperation of the magnetic seat 4, the main bracket 2 and the reinforcement plate 3. The bleed valve bracket 14 and the rocker arm 15 are combined with the bleed valve adjustment sleeve 17 to provide support for the bleed valve and allow its position to be precisely adjusted. The dial gauge 13 is installed on the bleed valve stem 16, directly displaying the pressure value for accurate pressure regulation. During the pressure regulation process, the operator first adjusts the pressure to a preset value lower than the required pressure through the pressure regulating valve, which is calculated based on the pressure increment corresponding to each millimeter displacement of the valve stem. Then, close the corresponding switch and observe the reading on the dial gauge 13. If it is consistent with the expectation, it is confirmed that the preload pressure is set correctly; if there is a deviation, the position of the bleed valve adjustment sleeve 17 needs to be readjusted. It makes it efficient to set and test the pressure of each machine, because the value of the digital pressure regulating valve does not need to be adjusted again after the first setting, which greatly simplifies the setting process of subsequent machines. The design of the entire pneumatic device not only ensures the accuracy of the adjustment, but also improves the operating efficiency, and meets the needs of quickly setting the turbocharger pressure.
