purpose

Used in water supply and drainage, flood prevention, water conservancy and hydropower engineering to cut off and dredge water flow. Especially in scenic areas, road engineering, and structures, it is not suitable to install and use exposed cast iron inlaid copper gates.

Structure and Characteristics

The equipment consists of door frame, door panel sealing ring, transmission nut, and adjustable wedge block and other components. It has the characteristics of simple structure, durability, easy installation, and good concealment.

Main technical parameters

1. The gate is installed on the wall, and the door panel is usually set on the upstream side (one-way); Can withstand a maximum pressure of 0.1MPa, and can withstand water pressure on both sides of the door panel (in both directions): can withstand a maximum reverse pressure of 0.03 MPa

2. The maximum forward leakage of the sealed working surface is ≤ 1.25L/min · m. Reverse leakage rate ≤ 2.5L/min. m
