Bronze Gate for Wastewater Plant|Cast Iron Flow Control|Cast Iron Bronze-Seated Square Gate

Working Principle

When the hoist drives the threaded stem to rotate, the gate moves vertically. Upon closing, the wedge blocks on the gate plate press tightly against the bronze seat on the frame. The equipment uses an adjustable wedge design. Even if long-term use causes wear, you can simply tighten the bolts to press the plate against the bronze seat again, ensuring a long-lasting, leak-free seal.

Application Fields

1.Sewage interception wells: interception in combined sewer systems to prevent direct discharge into rivers.
2.Pump station inlets: protecting pumps and precisely controlling inlet flow.
3.Equalization and settling tanks: isolation for maintenance and effective water level regulation.
4.Industrial wastewater treatment: isolation of collection tanks in electroplating and printing/dyeing plants.

FAQ

Q1: The wastewater plant environment is highly corrosive. Is this gate rust-proof?
A: Yes. The body and frame are made of high-quality cast iron with an epoxy resin coating. The lifting stem in contact with water is stainless steel. Most importantly, the sealing face is inlaid with tin bronze, which is not only wear-resistant but also highly resistant to corrosion. A Bronze Gate for Wastewater Plant maintains a long service life even when dealing with complex water quality.

Q2: Can this square gate close completely?
A: With the bronze sealing face and wedge compression mechanism, the leakage rate upon closing is extremely low (typically less than 1.25 liters/min·meter), achieving excellent shut-off. If slight leakage occurs, it can be re-sealed by adjusting the wedges.

Q3: Can it be equipped with an electric actuator?
A: Yes. The top of the gate has a standard flange. In addition to the manual handwheel, an electric hoist can be specified to tie into the wastewater plant's automated control system.
