AI Technical Summary
Technical Problem
Existing high-pressure rotary discharge valves rely on manual adjustment, resulting in slow response speed, low adjustment accuracy, easy leakage, and lack of real-time monitoring and emergency protection, leading to a high risk of seal failure.
Method used
The top pressure assembly is driven by a servo motor, and a closed-loop control system is formed by combining position, current, and pressure sensors with a controller to achieve automatic adjustment of the sealing torque, and an emergency protection is provided by an electromagnetic brake.
Benefits of technology
It achieves reliable and accurate sealing under high pressure, reduces wear on sealing strips, and improves the automation level and operational safety of the equipment.

Abstract
This utility model relates to an automatic high-pressure rotary discharge valve, which includes a valve body, a sealing strip disposed around the valve core, and a top-pressing assembly disposed within the valve core. The top-pressing assembly is driven by a drive assembly, which drives the top-pressing assembly to press against the sealing strip. The drive assembly is connected to a controller for controlling the output of the drive assembly. The controller is electrically connected to a position sensor, a current sensor, and a pressure sensor. This utility model has the effects of automatic regulation, reliable sealing, and precise control.
