[0003] 1. Automated operation: The fully automatic device can automatically complete the pressure test process, including pressurization, pressure maintenance, pressure reduction, leak detection and other steps, without manual intervention, reducing the errors and labor intensity caused by manual operation.

[0004] 2. Improve test accuracy: The automatic control system can set the test pressure and test time more accurately, thereby improving the accuracy and repeatability of the test.

[0005] 3. Real-time monitoring: The equipment is usually equipped with real-time monitoring and data logging functions, which can display various parameters during the test in real time and record the test results for subsequent analysis and tracking. In general, fully automatic valve pressure testing equipment greatly improves the efficiency and accuracy of the pressure testing process and is an important equipment in modern valve production and maintenance.

[0006] However, most existing fully automatic valve pressure testing devices use fixed ends to perform pressure tests. While this method can perform normal pressure tests, excessive test pressures can cause the valve to move or become unstable, affecting test accuracy. To address this issue, we propose a fully automatic valve pressure testing device to address these issues. Utility Model Content
