Description

Technical Field

[0002] Most wastewater treatment plants are equipped with regulating reservoirs, and the hydraulic gate valve is the main control equipment for the influent of the regulating reservoir, and it is an imported device. For example... Figure 1 As shown, the automatic opening and closing of the hydraulic gate 1 is mainly based on the water level in the inlet channel. Hydraulic cylinders 2 are installed on both sides of the hydraulic gate 1, each containing a position sensor to ensure synchronization during opening and closing. However, the position sensors have a high failure rate during operation. If the positional error of the hydraulic cylinders 2 on both sides exceeds 20mm, the hydraulic gate 1 will fail to open and close properly, severely affecting the normal operation of the regulating reservoir.

[0003] Hydraulic gates typically employ a drive system using hydraulic cylinders on both sides. However, in practical applications, this method often results in the hydraulic cylinders on both sides being out of sync, severely impacting the stability and reliability of the gate's opening and closing, and posing safety hazards.
