AI Technical Summary
Traditional bidirectional pressurization devices for pressure chambers are complex in structure and expensive, making it difficult to achieve continuous pressurization and pressure maintenance over long periods. Furthermore, their slow pressure regulation response leads to poor stability in high-pressure environments.
It adopts a single electromagnetic reversing valve and a double-headed piston system. The electromagnetic reversing valve automatically regulates the sealing ring and pressure sensor feedback to achieve long-term pressurization and pressure maintenance of a single system. Pressure fluctuations are offset by pressure monitoring and dynamic adjustment in the moving chamber to ensure pressure stability.
It simplifies the operation process, achieves long-term pressure stability and efficient pressure regulation, reduces equipment complexity and maintenance costs, and improves the stability and accuracy in high-pressure environments.
