AI Technical Summary
The existing electric check valves have a safety hazard because the power box socket and power plug are connected by a wiring harness. They are susceptible to corrosion, which can lead to problems such as leakage and poor contact.
The power input plug is integrated into the outer wall of the control box, and a low-voltage electrical connection is used. The drive components and the circuit board are electrically connected through the plug-in part, which simplifies the structure and avoids poor contact and wear of the wiring harness connection.
It significantly improves the safety and reliability of the product, reduces safety hazards caused by wire harness connections, and simplifies the product structure.
