purpose
Commonly used in water conservancy projects such as water supply, drainage, and flood prevention.

structure and characteristics
This equipment is mainly composed of door frames, gate plates, sealing rings, and adjustable wedge-shaped pressure blocks. After long-term wear and tear of the gate, its sealing surface can be adjusted by wedge-shaped pressure blocks to ensure normal operation. It has a reasonable and sturdy structure, strong wear and corrosion resistance, and reliable performance; Features such as easy installation, debugging, use, and maintenance.

Main technical parameters
1. The gate should be installed in the position shown in the diagram, and the gate should be set on the upstream face;
2. The gate allows for other high pressures of 0.1MPa when pressed against the door frame;
3. The gate can be pressed away from the door frame with a maximum pressure of 0.02MPa;
4. The leakage rate of the sealed working area shall not exceed 1.25L/min m.
